1 00:00:00,390 --> 00:00:06,220 So as you can see here I also implemented this view that unclick eggless or remove it. 2 00:00:06,250 --> 00:00:07,760 And as you can see here. 3 00:00:08,140 --> 00:00:16,320 They did it about an object and the image view object or both of them actually are the subclass of The 4 00:00:16,320 --> 00:00:17,570 View class. 5 00:00:17,580 --> 00:00:18,120 OK. 6 00:00:18,210 --> 00:00:26,400 So we can refer to those objects as views OK because there is actually an is a relationship between 7 00:00:26,400 --> 00:00:27,810 these objects. 8 00:00:28,040 --> 00:00:36,330 And as you can see here I can just switch between the ideas of my for example a button and my image 9 00:00:36,330 --> 00:00:41,670 view I want to differentiate between Actually my button and my image view. 10 00:00:41,700 --> 00:00:47,490 So whenever the user clicks on my button case our thoughts are indeed bitty. 11 00:00:47,530 --> 00:00:51,230 And so if the user clicks on the button here. 12 00:00:51,330 --> 00:00:53,660 I actually created an intent object. 13 00:00:53,760 --> 00:00:54,240 OK. 14 00:00:54,240 --> 00:00:58,120 Intent and the name of this object is intent. 15 00:00:58,230 --> 00:00:59,660 New intent. 16 00:00:59,730 --> 00:01:00,470 OK. 17 00:01:00,700 --> 00:01:07,410 And here are for the constructor of this class as you can see here main activity that this first of 18 00:01:07,410 --> 00:01:08,870 all we need to actually specify. 19 00:01:08,880 --> 00:01:12,590 So this is going to be the class that we want to actually move from. 20 00:01:12,660 --> 00:01:17,600 OK main activity that this this is going to be are of first argument. 21 00:01:17,730 --> 00:01:18,250 OK. 22 00:01:18,480 --> 00:01:22,790 And our second argument is the class that you're going to actually transfer to. 23 00:01:22,880 --> 00:01:23,450 OK. 24 00:01:23,580 --> 00:01:28,260 We want to actually transfer from this activity the main activity to the second activity. 25 00:01:28,260 --> 00:01:28,800 OK. 26 00:01:29,190 --> 00:01:31,070 So how we can do that. 27 00:01:31,080 --> 00:01:34,690 So in order to do that we need to actually create an intent object. 28 00:01:34,820 --> 00:01:35,350 OK. 29 00:01:35,700 --> 00:01:39,700 And here you can see here we don't have the second activity class yet. 30 00:01:39,730 --> 00:01:42,270 That's why it is now showing us an error. 31 00:01:42,420 --> 00:01:45,390 So we it actually creates that class that class in a minute. 32 00:01:45,390 --> 00:01:51,180 So the first that we actually are talking about these lines of quote here and here I want to actually 33 00:01:51,180 --> 00:01:57,140 pass some information from the main activity class to the second and second activity class. 34 00:01:57,150 --> 00:02:01,590 So in order to do that I need to just refer to the name of this intent intent. 35 00:02:01,620 --> 00:02:04,040 Object that put extra. 36 00:02:04,470 --> 00:02:10,490 And here we need to actually specify the key of the value that you want to pass to and other activity. 37 00:02:10,620 --> 00:02:12,730 So this name is actually the key. 38 00:02:12,930 --> 00:02:13,430 OK. 39 00:02:13,530 --> 00:02:14,750 Inside is double quotes. 40 00:02:14,910 --> 00:02:15,350 OK. 41 00:02:15,360 --> 00:02:18,030 And as you can see here this value is capitalized. 42 00:02:18,090 --> 00:02:20,880 So always capitalized your keys. 43 00:02:20,940 --> 00:02:21,520 OK. 44 00:02:21,900 --> 00:02:27,960 So this is our key name and the second one is that the second argument is the value that you want to 45 00:02:27,960 --> 00:02:31,830 actually pass from this activity to the second activity. 46 00:02:31,860 --> 00:02:35,410 It is the name that takes the two strings. 47 00:02:35,580 --> 00:02:36,270 OK. 48 00:02:36,510 --> 00:02:39,550 So as you can see here in say this activity minute example. 49 00:02:39,690 --> 00:02:48,330 So whatever value the user enter is this text here is going to be actually passed from this value to 50 00:02:48,330 --> 00:02:49,140 another value. 51 00:02:49,140 --> 00:02:49,690 OK. 52 00:02:50,070 --> 00:02:51,250 So I have this value here. 53 00:02:51,270 --> 00:02:53,790 It is the name that takes that to a string. 54 00:02:54,210 --> 00:02:59,960 And here as you can see intent that put extra email. 55 00:02:59,970 --> 00:03:00,580 So here it is. 56 00:03:00,630 --> 00:03:02,700 This is going to be our key email. 57 00:03:02,970 --> 00:03:04,900 As you can see here this is capitalized. 58 00:03:05,100 --> 00:03:11,250 And for the second argument I'm want to actually I actually specified the value that I want to pass 59 00:03:11,250 --> 00:03:13,440 from this activity to another activity. 60 00:03:13,560 --> 00:03:16,730 EDT e-mail that get text twisting. 61 00:03:17,220 --> 00:03:22,440 Again I have this line of code here intent that extra that put extra. 62 00:03:22,650 --> 00:03:29,340 And here I am specifying the key user underline name and the second one is there actually is actually 63 00:03:29,380 --> 00:03:34,110 the value that I want to pass from this main activity class to the second activity class. 64 00:03:34,120 --> 00:03:37,690 It is a username that takes the two strings. 65 00:03:38,190 --> 00:03:45,930 And here again intent that put extra password this is alci it is password gettext that to a string. 66 00:03:46,380 --> 00:03:47,920 And here it is. 67 00:03:48,030 --> 00:03:49,380 That puts extra. 68 00:03:49,500 --> 00:03:54,320 And here as you can see here I am actually specifying the key gender type. 69 00:03:54,570 --> 00:03:56,730 And the second value is the gender's type. 70 00:03:56,730 --> 00:04:01,890 So here as you can see in our main activity class I have this string value. 71 00:04:01,920 --> 00:04:04,000 It is a variable gender type. 72 00:04:04,020 --> 00:04:04,560 OK. 73 00:04:04,890 --> 00:04:11,520 So now as you can see I am specifying that the key is going to be gender type and I want to pass that 74 00:04:11,940 --> 00:04:15,980 string value from this activity to the second activity class. 75 00:04:16,440 --> 00:04:24,540 And now as you can see here because I want to I want also to actually pass this image from this activity 76 00:04:24,540 --> 00:04:25,840 to another activity. 77 00:04:25,980 --> 00:04:29,800 I also need to actually do something with that image. 78 00:04:29,820 --> 00:04:30,350 OK. 79 00:04:30,510 --> 00:04:37,590 So in order to actually pass one image from one activity to another activity you need to actually convert 80 00:04:37,950 --> 00:04:41,510 that image to an array of bytes. 81 00:04:41,610 --> 00:04:42,150 OK. 82 00:04:42,270 --> 00:04:50,130 So for that specific job I need to actually create an object of type byte array output stream as I did 83 00:04:50,130 --> 00:04:50,720 here. 84 00:04:50,730 --> 00:04:56,770 Both are a output stream and the name of this object is Stream new byte at a output stream. 85 00:04:56,880 --> 00:04:59,530 So here I actually created an object of type byte. 86 00:04:59,540 --> 00:05:06,910 Ari with stream and here I actually fared to the name of this a bitmap object that I actually declared 87 00:05:07,320 --> 00:05:11,540 inside this mean activity class bitmap bitmap object. 88 00:05:11,610 --> 00:05:14,580 So here as you can see bitmapped does compress. 89 00:05:14,700 --> 00:05:18,440 So hit it because I want to actually pass this image to another other activity. 90 00:05:18,600 --> 00:05:25,950 I need to actually compress this image this bitmap object so bitmap that compress for the first argument 91 00:05:26,010 --> 00:05:31,350 I need to specify the format of the image that I want to pass from this activity to another activity 92 00:05:31,590 --> 00:05:34,670 bitmap that compress format that P and G. 93 00:05:34,680 --> 00:05:38,640 OK so our image is going to be at an IP and defined. 94 00:05:38,670 --> 00:05:39,300 OK. 95 00:05:39,690 --> 00:05:43,630 And for the second argument we need to specify the quality of our image. 96 00:05:43,680 --> 00:05:52,160 So 100 is good enough and for the first argument we need to specify the byte Aure outputs an object 97 00:05:52,230 --> 00:05:53,250 as you can see here. 98 00:05:53,400 --> 00:06:03,720 I assigned this object here for the first argument and here in line 82 I actually created an array of 99 00:06:03,720 --> 00:06:04,630 type byte. 100 00:06:04,680 --> 00:06:05,190 OK. 101 00:06:05,460 --> 00:06:12,960 And the name of this area is byte array assignment operator and here as you can see I referred to the 102 00:06:12,960 --> 00:06:15,150 name of this object byte. 103 00:06:15,180 --> 00:06:16,560 Are they out with the stream object. 104 00:06:16,560 --> 00:06:19,410 Stream dots to bite arii. 105 00:06:19,470 --> 00:06:26,160 So I am actually converting this stream object to actually to our bite array object and that I am assigning 106 00:06:26,190 --> 00:06:28,670 that value to despite the error here. 107 00:06:28,740 --> 00:06:29,580 As you can see. 108 00:06:29,680 --> 00:06:35,930 And here I am actually ascending this image to another activity intent that puts extra. 109 00:06:36,210 --> 00:06:36,580 OK. 110 00:06:36,630 --> 00:06:38,530 Intent does put extra. 111 00:06:38,550 --> 00:06:41,820 So for the first argument as against it see is going to be ARCI. 112 00:06:41,970 --> 00:06:45,530 So remember always capitalize your keys. 113 00:06:45,660 --> 00:06:47,170 So I just need to type in here. 114 00:06:47,210 --> 00:06:50,110 Peak sure as it against here. 115 00:06:50,460 --> 00:06:53,110 And our second argument is bytes at a. 116 00:06:53,110 --> 00:06:54,900 Here as you can see. 117 00:06:55,350 --> 00:07:03,040 And now as you can see here I am actually starting this activity here start the activity intense. 118 00:07:03,300 --> 00:07:08,400 So here are because I want to move from this activity to another activity I need to write this code 119 00:07:08,400 --> 00:07:10,170 here to start activity intent. 120 00:07:10,170 --> 00:07:13,980 So it is going to actually open the second activity and then it's going to actually pass these values 121 00:07:14,430 --> 00:07:16,660 from this activity to another activity. 122 00:07:17,010 --> 00:07:21,210 So now I need to actually create the second activity class. 123 00:07:21,240 --> 00:07:21,750 OK. 124 00:07:21,930 --> 00:07:28,710 So in order to do that because all you want to actually create an activity here I need to I can just 125 00:07:28,920 --> 00:07:30,640 click on this package here. 126 00:07:30,710 --> 00:07:33,970 That example that Matas or saw that that at 44 here. 127 00:07:34,170 --> 00:07:40,920 Just select this package and then click on File New and then click on activity. 128 00:07:40,950 --> 00:07:46,760 As you can see here we have this activity here and now a selectees empty activity here. 129 00:07:46,930 --> 00:07:49,830 You can actually you can actually select these activities here. 130 00:07:49,980 --> 00:07:54,220 But for our application just select this empty activity. 131 00:07:54,270 --> 00:07:57,800 And now we can actually specify the name of your activities. 132 00:07:57,820 --> 00:08:02,820 So just type in here a activity. 133 00:08:03,600 --> 00:08:06,780 Here as you can see it says generate a find. 134 00:08:06,900 --> 00:08:09,360 So make sure that this option is actually checked. 135 00:08:09,360 --> 00:08:15,870 So it's going actually to create a layout file for you for your activity and here this is going to be 136 00:08:15,870 --> 00:08:22,650 the name of our out activity the line segment and this is going to be our package that this activity 137 00:08:22,650 --> 00:08:24,170 is going to be inside it. 138 00:08:24,600 --> 00:08:32,310 So now click on finish and now as you can see our activity our second activity is actually created and 139 00:08:32,310 --> 00:08:37,740 here inside is lay out fight as you can see we have this activity underline say in that example here 140 00:08:38,190 --> 00:08:40,990 that is actually related to the second activity that goes up. 141 00:08:41,100 --> 00:08:44,320 So here as you can see we have dismasted set content view. 142 00:08:44,490 --> 00:08:47,590 Our thoughts lay out that activity the second segment. 143 00:08:47,640 --> 00:08:53,670 So this is our ASML fight that is related to this activity here second activity that of a fight and 144 00:08:53,700 --> 00:08:59,730 in our Android manifest here as you can see we also have this line of code here. 145 00:08:59,940 --> 00:09:05,940 So the idea is automatically generated this line of code for us activity and Royte name that second 146 00:09:05,940 --> 00:09:06,710 activity. 147 00:09:06,870 --> 00:09:07,630 OK. 148 00:09:07,830 --> 00:09:15,750 So now we also declared this our second activity in our manifest here and now. 149 00:09:15,750 --> 00:09:21,000 So first of all let's actually go back to our activity Underland second that example here and now I 150 00:09:21,000 --> 00:09:27,280 want to actually design the user interface of our second activity class. 151 00:09:27,390 --> 00:09:28,110 OK. 152 00:09:28,320 --> 00:09:36,810 So now OK now I want to actually design the user interface of our second activity so first of all let's 153 00:09:36,810 --> 00:09:41,690 actually track a linearly out vertical at the center of this relatively out here. 154 00:09:41,760 --> 00:09:42,240 OK. 155 00:09:42,240 --> 00:09:48,550 These are relatively out and I put this linearly out vertical at the center of this relatively out. 156 00:09:48,570 --> 00:09:54,480 OK so now let's actually drag an image view into this linearly out vertical. 157 00:09:54,540 --> 00:10:01,120 So as you can see here inside these widgets folder I have this image view here just selected at and 158 00:10:01,150 --> 00:10:04,670 put it at the center of this linearly outwards. 159 00:10:04,930 --> 00:10:12,460 And as you can see here let's actually assign the value hundred for the layout of this of this image 160 00:10:12,520 --> 00:10:14,090 view 200. 161 00:10:14,380 --> 00:10:19,010 And it's actually assigned the value 200 for the layout height of this image. 162 00:10:19,060 --> 00:10:21,290 And then press on until key on your keyboard. 163 00:10:21,670 --> 00:10:26,200 And as you can see here the layout gravity is centered horizontal. 164 00:10:26,480 --> 00:10:36,900 And now let's actually assign an ID to this image view our AMG animal received and then press on into 165 00:10:36,940 --> 00:10:37,990 here on your keyboard. 166 00:10:38,170 --> 00:10:41,940 So the idea of this image is all in the animal received. 167 00:10:42,040 --> 00:10:50,350 OK and now let's actually select this takes your large takes you inside these widgets folder and put 168 00:10:50,350 --> 00:10:52,770 it inside is linearly as vertical OK. 169 00:10:52,780 --> 00:10:53,690 Just put it here. 170 00:10:53,830 --> 00:11:01,270 Below these are image view and double click on it just deletes the text of this text view and for the 171 00:11:01,270 --> 00:11:10,210 ID just type in here takes the name or KTXA the name and then press on enter key on your keyboard. 172 00:11:10,730 --> 00:11:14,960 And that's actually assigned a value match Pallant for the layout. 173 00:11:14,980 --> 00:11:22,830 Which of these takes you so select this match parent here and now present enter key on your keyboard. 174 00:11:22,900 --> 00:11:23,530 OK. 175 00:11:23,830 --> 00:11:28,460 And then Arliss actually as you can see here the left gravity is centered horizontally. 176 00:11:28,600 --> 00:11:33,590 And now essentially find the gravity attribute that is related to the state's view. 177 00:11:33,700 --> 00:11:35,890 So this is our gravity attribute. 178 00:11:35,890 --> 00:11:36,500 Open it. 179 00:11:36,670 --> 00:11:41,470 And that's actually as you can see it this is our center horizontal attribute that is related to the 180 00:11:41,470 --> 00:11:45,090 space view just accelerated and checked is checkbooks. 181 00:11:45,160 --> 00:11:45,640 OK. 182 00:11:45,700 --> 00:11:51,730 So it's going to actually center the children of these states so that the children of this this is going 183 00:11:51,730 --> 00:11:53,490 to be the text of the state's view. 184 00:11:53,500 --> 00:11:57,500 So if it sticks you and just assign a text to the state's view. 185 00:11:57,640 --> 00:12:03,190 Now as you can see the text is actually at the center horizontal of this takes you here. 186 00:12:03,190 --> 00:12:04,020 OK. 187 00:12:04,330 --> 00:12:08,370 So it's a double click on it and deletes the text of this text view. 188 00:12:08,410 --> 00:12:13,270 Now let's actually write and order a text view into this linearly I-30 call. 189 00:12:13,300 --> 00:12:20,500 So just select it and put it below this takes you here and inside the city nearly out vertical and WTNH 190 00:12:20,860 --> 00:12:22,430 deletes the text of the state's view. 191 00:12:22,450 --> 00:12:29,950 And for the idea just typing here takes the email th the e-mail received and then our press Enter key 192 00:12:29,950 --> 00:12:31,560 on your keyboard. 193 00:12:32,350 --> 00:12:41,100 And then again for the lay out with assigned the value match Pallant and actually find the let's actually 194 00:12:41,100 --> 00:12:46,490 find the gravity attribute this is the gravity attribute that is related to the state's view and then 195 00:12:46,490 --> 00:12:49,340 our checked is our center horizontal here. 196 00:12:49,590 --> 00:12:50,660 As you can see. 197 00:12:50,850 --> 00:12:57,730 And let's actually right another large stakes into this linearly vertical and put it at the center horizontally 198 00:12:58,040 --> 00:13:01,220 OK of these are linearly aesthetical OK. 199 00:13:01,290 --> 00:13:06,500 Just put it at the center horizontal double clicked on it deletes the text of the state's view and for 200 00:13:06,510 --> 00:13:16,290 the ID just type in here TXI the user name and then press on entelechy on your keyboard and faultily 201 00:13:16,290 --> 00:13:16,750 outfit. 202 00:13:16,800 --> 00:13:20,520 Assign the value match parent match parent. 203 00:13:20,740 --> 00:13:23,640 And let's actually find that gravity attributes. 204 00:13:23,670 --> 00:13:30,470 This is the gravity attribute and then select the center horizontal here and check this checkbox. 205 00:13:30,480 --> 00:13:36,450 So now let's actually right and our other large takes you into this linearly as vertical and put it 206 00:13:36,480 --> 00:13:39,090 at the center horizontal of this linearly. 207 00:13:39,090 --> 00:13:39,950 I swear to god. 208 00:13:40,230 --> 00:13:45,630 So this is our last this year and I'm going to put it at the center horizontal of this linearly at Hollys 209 00:13:46,050 --> 00:13:47,380 linearly Ellsworthy Karl. 210 00:13:47,700 --> 00:13:54,150 Double click on it delete the text of this text view and for the ID just type in here takes the password 211 00:13:56,070 --> 00:13:59,810 and then press on Enter key on your keyboard again. 212 00:13:59,940 --> 00:14:06,960 Assign the value of match parent for the layout of this RTX the passport here. 213 00:14:07,200 --> 00:14:10,170 And let's actually find the gravity attribute here. 214 00:14:10,230 --> 00:14:12,510 As you can see this is the gravity attribute. 215 00:14:12,690 --> 00:14:20,070 And then let's actually check this center horizontal checkbox here and now. 216 00:14:20,280 --> 00:14:26,300 Let's actually go back to our main activity class here and here as you can see I am actually passing 217 00:14:26,550 --> 00:14:30,330 these values to that to the next activity to the second activity. 218 00:14:30,360 --> 00:14:33,000 And as you can see here this area is gone. 219 00:14:33,000 --> 00:14:36,490 Second activity that class and here I to actually pass these values. 220 00:14:36,510 --> 00:14:39,720 Name email username password gender type. 221 00:14:39,960 --> 00:14:46,410 And then here I am I am I truly I want to pass the image from this activity to another activity. 222 00:14:46,410 --> 00:14:47,070 OK. 223 00:14:47,370 --> 00:14:53,720 And I actually decided to convert that image to to actually a bite out of a output stream. 224 00:14:53,940 --> 00:14:57,090 And here as you can see it bitmap that compress. 225 00:14:57,120 --> 00:15:01,240 And here I am actually compressing that image bitmap. 226 00:15:01,500 --> 00:15:05,780 And here I created an array of type byte. 227 00:15:06,090 --> 00:15:14,310 And here I actually called these two byte RMF at on this string object here that is of type byte array 228 00:15:14,310 --> 00:15:15,310 out with STREAM. 229 00:15:15,390 --> 00:15:21,960 And then here I want to actually pass this a byte at a here to the second activity intense that put 230 00:15:21,960 --> 00:15:22,430 extra. 231 00:15:22,440 --> 00:15:24,890 This is going to be the key and point at me. 232 00:15:24,990 --> 00:15:30,450 So I actually converted my image to I got to actually a byte array. 233 00:15:30,730 --> 00:15:37,370 OK to an array of bytes and then I can actually pass this image from this activity to the second activity. 234 00:15:37,620 --> 00:15:42,740 And here I am actually starting the second activity start activity intense break. 235 00:15:43,110 --> 00:15:46,380 And as you can see here we have another case statement here. 236 00:15:46,400 --> 00:15:49,190 Case that ID that I am the animal. 237 00:15:49,470 --> 00:15:56,070 And here I created another intent object intent intent image new intent. 238 00:15:56,220 --> 00:16:00,210 And here I want to actually open this action. 239 00:16:00,240 --> 00:16:02,360 Intent that action gets content. 240 00:16:02,370 --> 00:16:09,150 So I want to actually open the photos of my actually device the photos application of my device and 241 00:16:09,150 --> 00:16:14,340 then I can actually access the images that are inside of my device. 242 00:16:14,340 --> 00:16:14,890 OK. 243 00:16:15,120 --> 00:16:19,540 So here I referred to this object intent image that said type. 244 00:16:19,800 --> 00:16:20,360 OK. 245 00:16:20,580 --> 00:16:26,560 So here I want to actually open the photos application image slash start. 246 00:16:26,640 --> 00:16:27,130 OK. 247 00:16:27,210 --> 00:16:32,550 So I need to put these values in so the double quotes and here are because I want to actually get an 248 00:16:32,550 --> 00:16:37,140 image from my Actually for my photos application in my device. 249 00:16:37,140 --> 00:16:41,280 I need to actually call this summer if it starts activity for resolved. 250 00:16:41,580 --> 00:16:41,950 OK. 251 00:16:41,970 --> 00:16:47,000 This is very important because we want to receive an image from my photos application in my device. 252 00:16:47,130 --> 00:16:52,470 I need to call the Smurfette start activity for resolved Internet image image request court. 253 00:16:52,650 --> 00:16:57,840 So as you can see here in our main activity class I created this constant. 254 00:16:57,970 --> 00:16:59,680 OK this is our image request. 255 00:16:59,870 --> 00:17:00,690 1000. 256 00:17:00,810 --> 00:17:01,410 OK. 257 00:17:01,680 --> 00:17:06,340 And this is our image request code that is related only to this image. 258 00:17:06,350 --> 00:17:11,970 I need you anymore object because whenever the user clicks on that image it's going to open the photo 259 00:17:12,030 --> 00:17:16,970 application and then we can actually select an image and then we can receive that image. 260 00:17:16,980 --> 00:17:23,700 And this is really important that we have a unique request code for that because there are components 261 00:17:23,760 --> 00:17:24,740 on my screen. 262 00:17:24,870 --> 00:17:31,530 May want to access the photos application but this requires code that determines the images that are 263 00:17:31,530 --> 00:17:33,830 actually received by clicking on this. 264 00:17:33,840 --> 00:17:40,630 I am the animal is going to be actually specifically for this I am the animal image for you. 265 00:17:40,800 --> 00:17:47,070 And here I actually tighten break so that it's going to actually break out of this sweet statement. 266 00:17:47,070 --> 00:17:55,620 So here because you want to actually want to receive an image from the photos application by clicking 267 00:17:55,710 --> 00:18:02,070 on this or by clicking on this image of you need to actually overwrite the activity of the activity 268 00:18:02,070 --> 00:18:02,950 results method. 269 00:18:03,000 --> 00:18:07,710 So now as you can see our application is actually running on this emulator. 270 00:18:07,710 --> 00:18:13,470 So let's actually click on this image here and now as you can see our photos application is actually 271 00:18:13,470 --> 00:18:13,940 opened. 272 00:18:13,950 --> 00:18:17,420 And I can actually select an image for here. 273 00:18:17,490 --> 00:18:24,090 So now I can actually select for example just this internal storage. 274 00:18:24,090 --> 00:18:29,370 So just a click on the menu he had menu button and then click on this internal storage. 275 00:18:29,370 --> 00:18:36,990 And here I can actually select these pictures directory as you can see here we have this we have these 276 00:18:36,990 --> 00:18:41,490 pictures directory and here inside these animal images. 277 00:18:41,490 --> 00:18:42,840 I have these images here. 278 00:18:42,840 --> 00:18:43,390 OK. 279 00:18:43,530 --> 00:18:46,580 So here I can just select the spirit that PND. 280 00:18:46,800 --> 00:18:49,610 And now you can see we don't see that image here. 281 00:18:49,620 --> 00:18:50,200 OK. 282 00:18:50,250 --> 00:18:56,370 So that's why we need to actually override the unactivated results method because we want to receive 283 00:18:56,580 --> 00:18:59,750 an image from the photos application in our device. 284 00:18:59,910 --> 00:19:04,920 So in order to do that I actually pasted some of it here and now I'm going to explain to you what's 285 00:19:04,920 --> 00:19:06,220 going on here. 286 00:19:06,240 --> 00:19:11,520 So as you can see here before the access modifier of this method is protected so only the subclasses 287 00:19:12,480 --> 00:19:20,880 of the so so so only are the subclasses of the activity class can actually can actually overwrite Smurfette 288 00:19:20,910 --> 00:19:22,370 or access this method. 289 00:19:22,650 --> 00:19:28,770 So the the the access modifier is protected and the return type is void. 290 00:19:28,770 --> 00:19:31,370 So this means that this is going to return nothing. 291 00:19:31,410 --> 00:19:32,140 OK. 292 00:19:32,520 --> 00:19:35,440 And the name of the Smurfette is an activity result. 293 00:19:35,640 --> 00:19:37,620 And we have free arguments here. 294 00:19:37,770 --> 00:19:38,350 OK. 295 00:19:38,430 --> 00:19:40,140 It requires code. 296 00:19:40,260 --> 00:19:45,520 OK so this is the request code an e-mail request quote that I actually declared here. 297 00:19:45,600 --> 00:19:49,130 As you can see Final in our image request code 1000. 298 00:19:49,140 --> 00:19:50,000 OK. 299 00:19:50,370 --> 00:19:55,510 And here as you can see into request code in result code in intent data. 300 00:19:55,740 --> 00:19:57,710 OK so we have these arguments. 301 00:19:57,750 --> 00:20:04,230 So whenever we want to actually receive some data from another application or from another activity 302 00:20:04,470 --> 00:20:07,530 we need to override this on activity resolved. 303 00:20:07,530 --> 00:20:07,810 OK. 304 00:20:07,830 --> 00:20:14,970 And then we also need to actually open that activity or open that application or by using this method 305 00:20:15,090 --> 00:20:16,880 start activity for result. 306 00:20:16,920 --> 00:20:24,270 Ok not this start activity start activity for result and then we need to pass the intent and our request 307 00:20:24,270 --> 00:20:24,660 code. 308 00:20:24,660 --> 00:20:25,140 OK.
