1 00:00:00,100 --> 00:00:05,920 Hire everyone in this tutorial we're going to go ahead and create another Android application. 2 00:00:05,940 --> 00:00:06,960 So just click on this. 3 00:00:06,990 --> 00:00:13,260 Start in your Android studio project here and then for the name of your application just type in here 4 00:00:13,270 --> 00:00:14,970 app 45. 5 00:00:15,240 --> 00:00:20,770 And here you can actually specify the company domain package name and product location and then click 6 00:00:20,770 --> 00:00:27,650 on next here for the minimum STK choose AP is 16 Android 4.1 jelly bean. 7 00:00:27,930 --> 00:00:30,000 And then click on next here. 8 00:00:30,210 --> 00:00:31,830 Choose an empty activity. 9 00:00:31,830 --> 00:00:32,490 OK. 10 00:00:32,670 --> 00:00:37,060 So not notice that we have a blank activity and an empty activity. 11 00:00:37,120 --> 00:00:40,630 Choose empty activity OK and then reconnect. 12 00:00:40,710 --> 00:00:42,730 Here don't change anything. 13 00:00:42,870 --> 00:00:44,280 And then we can finish. 14 00:00:44,400 --> 00:00:47,890 So now as you can see our project is actually created. 15 00:00:47,970 --> 00:00:49,770 So it's actually double click on these arrays. 16 00:00:49,770 --> 00:00:50,730 Folder here. 17 00:00:51,030 --> 00:00:56,270 And then double click on this layout folder and then double click on this activity underline main that 18 00:00:56,300 --> 00:00:56,710 examen. 19 00:00:56,730 --> 00:00:57,630 OK. 20 00:00:57,690 --> 00:01:00,270 So here as you can see this is our Excel file. 21 00:01:00,420 --> 00:01:05,380 So just click on this hell over that takes you here and then press on delete key on your keyboard. 22 00:01:05,490 --> 00:01:11,850 So it's actually drag a linearly out vertical at the center of this relatively OK. 23 00:01:12,000 --> 00:01:17,850 So just select this linearly as vertical here inside the layouts folder and then put it at the center 24 00:01:18,120 --> 00:01:20,090 of this relatively out. 25 00:01:20,100 --> 00:01:22,650 So here is our linearly out vertical. 26 00:01:22,650 --> 00:01:27,730 So now let's actually direct our button into this linearly at vertical. 27 00:01:27,780 --> 00:01:29,210 So just select this button here. 28 00:01:29,220 --> 00:01:35,110 Inside this we just fold there and then put it at the center of this linearly L2 vertical. 29 00:01:35,160 --> 00:01:35,780 OK. 30 00:01:36,120 --> 00:01:42,930 And then just for the layout is assigned a value match Pallant here and double click on this button 31 00:01:42,930 --> 00:01:45,810 here for the text just typing in here. 32 00:01:45,870 --> 00:01:54,090 Let's open UDMA that come OK. 33 00:01:54,150 --> 00:02:03,690 And for the idea to step in here of PTEN open you the me and then press on Enter key on your keyboard. 34 00:02:04,260 --> 00:02:10,110 And now let's actually drag and other a button into this linearly out vertical and for the layout. 35 00:02:10,110 --> 00:02:16,970 We've assigned a value match Pallant here and double click on it here for the text just typing here 36 00:02:16,980 --> 00:02:30,420 let's search the google and then for the ID just typing here Pythian search Google and then press on 37 00:02:30,630 --> 00:02:32,550 until key on your keyboard. 38 00:02:32,610 --> 00:02:36,960 So now it's actually drag another button into this linearly as vertical. 39 00:02:36,960 --> 00:02:43,550 So just put it at the center of this linearly alphabetical OK and for the layout we assign the value 40 00:02:43,560 --> 00:02:44,540 match parent. 41 00:02:44,580 --> 00:02:48,480 Here and Now double click on it. 42 00:02:48,480 --> 00:02:54,360 So now for the text just typing here let's call someone. 43 00:02:55,200 --> 00:03:01,030 And for the ID just type in here between call and then person Enter key on your keyboard. 44 00:03:01,170 --> 00:03:07,470 And now let's actually drag another repotted into this linearly out vertical and put it at the center 45 00:03:07,710 --> 00:03:10,050 of this linearly vertical OK. 46 00:03:10,290 --> 00:03:15,600 And for the layout we assign the value match parent and double click on it. 47 00:03:15,600 --> 00:03:27,620 So for the text just typing in here lets access the dial pad and for the ID just typing here between 48 00:03:27,900 --> 00:03:30,420 access dial pad 49 00:03:33,430 --> 00:03:37,220 OK and then a person Enter key on your keyboard. 50 00:03:37,730 --> 00:03:43,070 So now let's actually select all of these buttons here. 51 00:03:43,430 --> 00:03:44,080 OK. 52 00:03:44,450 --> 00:03:48,280 And now let's actually find out the background attributes. 53 00:03:48,290 --> 00:03:53,540 So here as you can see this is the the this is the background attribute that is related to all of these 54 00:03:53,930 --> 00:03:57,490 buttons here and here I want to actually assign a color. 55 00:03:57,530 --> 00:04:06,260 So here I just need to put in hash tag and put this value here at 0 0 F F F F and then press on until 56 00:04:06,260 --> 00:04:07,940 key on your keyboard. 57 00:04:07,940 --> 00:04:12,080 So now as you can see the color back in and color of these buttons changed. 58 00:04:12,200 --> 00:04:15,060 So now let's actually select this linearly or vertical. 59 00:04:15,140 --> 00:04:20,570 And here I want to actually change the background color of this linearly alphabetical. 60 00:04:20,600 --> 00:04:28,720 So here again just typing here hashtag and here just type in here 45 F F D 5. 61 00:04:29,120 --> 00:04:31,910 And then press on Enter key on your keyboard. 62 00:04:31,910 --> 00:04:38,050 So as you can see here now I actually changed the background color of this nearly 20 code. 63 00:04:38,180 --> 00:04:44,040 So now let's actually run our project and see the user interface of our application. 64 00:04:44,060 --> 00:04:49,570 So here it actually changed the image emulator to Nexus 5. 65 00:04:49,690 --> 00:04:50,110 OK. 66 00:04:50,180 --> 00:04:57,140 So here I just need to choose this lunch emulate it and then I can select between these emulators. 67 00:04:57,140 --> 00:05:05,390 So here I was Nexus 5 API 23 and then I actually checked the search box here that says Use Sainty file 68 00:05:05,440 --> 00:05:09,380 save device for future launches and then press on. 69 00:05:09,470 --> 00:05:10,580 OK here. 70 00:05:10,850 --> 00:05:14,650 So now it's going to actually launch the emulator for me. 71 00:05:15,050 --> 00:05:19,330 So now as you can see our application is running on this emulator. 72 00:05:19,430 --> 00:05:22,830 And here is the design of our application. 73 00:05:22,850 --> 00:05:27,640 So now let's actually go back to our main activity that java file here and here we can actually put 74 00:05:27,650 --> 00:05:29,230 in our own codes here. 75 00:05:29,480 --> 00:05:36,440 So first of all because we want to actually access the Internet and the Carleen feature of our device 76 00:05:36,470 --> 00:05:39,650 first mini to actually open the manifest file. 77 00:05:39,950 --> 00:05:46,070 And here after the application tag here we want to actually specify that we want to use some of the 78 00:05:46,070 --> 00:05:50,660 features of Android and we to actually use those permissions. 79 00:05:50,660 --> 00:05:58,340 So here I just need to open a tag here and here I can just type in users permission and here I want 80 00:05:58,340 --> 00:06:02,760 to specify that I want to actually call someone call someone. 81 00:06:02,780 --> 00:06:05,370 So here I can just type in call form. 82 00:06:05,570 --> 00:06:12,890 OK and then our press Enter key on my keyboard and in here I need to actually close this task here. 83 00:06:13,220 --> 00:06:19,340 So here I am actually specifying that you want to call a phone and you need to actually access that 84 00:06:19,340 --> 00:06:20,300 permission. 85 00:06:20,480 --> 00:06:28,100 Again I want to actually use another permission user's permission access network state. 86 00:06:28,100 --> 00:06:34,430 So here is the access network state permission and then he had to select it and then person and Turkey 87 00:06:34,460 --> 00:06:38,280 on my keyboard and then I need to actually close this take here. 88 00:06:38,840 --> 00:06:39,770 OK. 89 00:06:39,770 --> 00:06:43,200 And here again we want to actually access the Internet. 90 00:06:43,220 --> 00:06:52,610 So here I just need to open attack user's permission and here I am just typing Internet and then press 91 00:06:52,760 --> 00:06:55,940 enter key on my keyboard and then close the stack. 92 00:06:56,030 --> 00:06:56,930 OK. 93 00:06:56,930 --> 00:07:02,150 So here in our main activity that double file we need to actually again put putting some lines of code 94 00:07:02,150 --> 00:07:05,170 regarding the permission to phone call. 95 00:07:05,180 --> 00:07:05,670 OK. 96 00:07:05,810 --> 00:07:11,780 Because we want to actually call someone in our application we need to actually put some lines of code 97 00:07:11,780 --> 00:07:19,910 here in order to ask the user whether they want to actually application whether they allow the application 98 00:07:20,210 --> 00:07:22,850 to call someone else or not. 99 00:07:22,920 --> 00:07:29,060 OK so here I want to put those lines of code here and I'm going to paste them and then explain to you 100 00:07:29,060 --> 00:07:30,390 what's going on here. 101 00:07:30,410 --> 00:07:36,680 So here in our main activity class first of all we need to specify what is going to be the request code 102 00:07:36,830 --> 00:07:37,910 for our permission. 103 00:07:37,970 --> 00:07:38,510 OK. 104 00:07:38,600 --> 00:07:41,110 So here I'm going to paste in this line of code here. 105 00:07:41,150 --> 00:07:48,000 As you can see the access modifier of this of this constant is private. 106 00:07:48,050 --> 00:07:50,230 This constant is actually static. 107 00:07:50,350 --> 00:07:51,300 OK. 108 00:07:51,350 --> 00:07:58,340 And this is actually the final constant the data type of this constant is integer and the name of this 109 00:07:58,340 --> 00:07:59,640 constant is called. 110 00:07:59,660 --> 00:08:00,270 OK. 111 00:08:00,500 --> 00:08:03,420 And I assigned disvalue number one to this constant. 112 00:08:03,440 --> 00:08:11,390 So this is going to be the request code OK for our calling permission OK because we want to call someone 113 00:08:11,630 --> 00:08:17,320 we need to actually create our request code that is actually specific for that past. 114 00:08:17,330 --> 00:08:23,120 OK so whenever the user clicks on this for example on this button here let's call someone. 115 00:08:23,300 --> 00:08:27,040 This request code is specifically related to this. 116 00:08:27,050 --> 00:08:32,630 But in our case with this feature that I want to actually call that someone OK. 117 00:08:32,730 --> 00:08:39,780 So this is very important and now so because there are user interface components may want to actually 118 00:08:40,110 --> 00:08:49,080 access the call and call someone of any to actually provide specific request codes for those user interface 119 00:08:49,080 --> 00:08:50,070 components. 120 00:08:50,070 --> 00:08:57,300 But this man this using this call request called here is going to be only for these let's call them 121 00:08:57,300 --> 00:08:58,860 once someone butts in here. 122 00:08:58,860 --> 00:08:59,310 OK. 123 00:08:59,340 --> 00:09:06,750 So whenever the user touches this button here it is going to call someone OK it is going to access the 124 00:09:06,750 --> 00:09:12,660 card feature of the device and can someone and that's request code and that request could hear inside 125 00:09:12,690 --> 00:09:16,970 our main activity here is going to be only specific to that button. 126 00:09:17,040 --> 00:09:17,860 OK. 127 00:09:18,120 --> 00:09:24,420 So now I have a request code and the name of the request code is call and I assigned this value number 128 00:09:24,420 --> 00:09:27,340 one to this because it's called here to this constant. 129 00:09:27,630 --> 00:09:30,330 So here I'm going to paste in some lines of code here. 130 00:09:30,840 --> 00:09:34,920 So as you can see here I actually pasted these lines of code here. 131 00:09:34,980 --> 00:09:35,810 OK. 132 00:09:35,850 --> 00:09:37,900 And now I'm going to explain to you what's going on here. 133 00:09:38,070 --> 00:09:41,550 So here I actually created an array. 134 00:09:41,710 --> 00:09:41,880 OK. 135 00:09:42,030 --> 00:09:46,090 And array of type string and the name of my address is permissions. 136 00:09:46,110 --> 00:09:50,490 So as you can see here the access modifier of my address is private. 137 00:09:50,490 --> 00:09:52,190 My address is static. 138 00:09:52,260 --> 00:09:52,870 OK. 139 00:09:53,100 --> 00:09:58,320 And here inside inside my array I have only one value. 140 00:09:58,650 --> 00:10:02,090 OK manifest that permission that calls someone. 141 00:10:02,280 --> 00:10:04,530 OK so let me actually did that come here. 142 00:10:04,770 --> 00:10:09,070 So I have only one value one permission manifest that permission. 143 00:10:09,080 --> 00:10:09,640 That code. 144 00:10:09,660 --> 00:10:12,870 So I want to actually access the call feature of my device. 145 00:10:12,870 --> 00:10:13,280 OK. 146 00:10:13,350 --> 00:10:20,730 So here I need to ask the user whether they want to allow my application to access the call feature 147 00:10:20,760 --> 00:10:22,290 of the device or not. 148 00:10:22,560 --> 00:10:23,940 If they allow me. 149 00:10:24,030 --> 00:10:24,580 OK. 150 00:10:24,780 --> 00:10:28,180 If they allow me I can call someone if they don't allow me. 151 00:10:28,220 --> 00:10:30,230 I would not be able to call someone. 152 00:10:30,300 --> 00:10:30,760 OK. 153 00:10:30,810 --> 00:10:37,020 So here I have this method in order to ask the user whether they allow me to call someone or not.
