1 00:00:00,180 --> 00:00:07,710 So and other threats click on this package here new job class and the name of this class is going to 2 00:00:07,710 --> 00:00:09,140 be iTunes. 3 00:00:10,000 --> 00:00:13,260 Hush city client. 4 00:00:13,740 --> 00:00:21,870 So remember our application our mobile device is going to be the client and it's the iTunes the iTunes 5 00:00:22,290 --> 00:00:24,210 Web service is going to be the server. 6 00:00:24,330 --> 00:00:27,720 So we are the client and we want to get the data from the server. 7 00:00:27,810 --> 00:00:32,430 So that's why I actually created this class this class is going to actually connect to the server and 8 00:00:32,430 --> 00:00:35,410 download those data and then click on OK here. 9 00:00:35,490 --> 00:00:41,060 So here now we are inside of these items how shitty like a typical day in class. 10 00:00:41,070 --> 00:00:47,700 So now I'm going to actually pasting some lines of code here inside this iTunes has shitty client class 11 00:00:48,000 --> 00:00:50,570 and then I'm going to explain to you what's going on here. 12 00:00:50,820 --> 00:00:55,680 So the first line of code that I want to actually paste in here is this line of code here as you can 13 00:00:55,680 --> 00:00:56,240 see. 14 00:00:56,550 --> 00:01:01,140 So as you can see the access modifier of these variable is actually private. 15 00:01:01,170 --> 00:01:06,180 This is actually a static variable data type of this variable is strange. 16 00:01:06,180 --> 00:01:07,730 So we have a string value. 17 00:01:07,860 --> 00:01:08,490 OK. 18 00:01:08,850 --> 00:01:12,850 And the name of this variable is based u r l. 19 00:01:12,930 --> 00:01:18,480 So this is going to be the U R L that you want to actually get the the items that are right so high 20 00:01:18,520 --> 00:01:27,960 shitty POS colon slash slash iTunes that Apple dot com slash search question mark and the term is Michael. 21 00:01:28,140 --> 00:01:29,320 Plus Jackson. 22 00:01:29,600 --> 00:01:36,120 OK so now I'm going to actually pasting MF at here and then I'm going to explain to you what's going 23 00:01:36,120 --> 00:01:37,090 on here. 24 00:01:37,500 --> 00:01:42,240 So as you can see here these are the lines of code that are actually pasted here. 25 00:01:42,240 --> 00:01:42,720 OK. 26 00:01:42,900 --> 00:01:47,290 So now I'm going to explain to you step by step what's going on here. 27 00:01:47,310 --> 00:01:52,560 So as you can see here first of all this is actually the MF it and the access modifier of this method 28 00:01:52,590 --> 00:01:53,670 is public. 29 00:01:53,970 --> 00:01:56,720 The return type of this method is string. 30 00:01:56,850 --> 00:02:00,310 So this is going to return an object of types 3. 31 00:02:00,480 --> 00:02:01,010 OK. 32 00:02:01,170 --> 00:02:05,330 And the name of this method is get iTunes stuff data. 33 00:02:05,430 --> 00:02:08,510 So this is the name of this method right. 34 00:02:08,550 --> 00:02:12,120 And here you can see this if it actually accepts a no arguments. 35 00:02:12,180 --> 00:02:12,800 OK. 36 00:02:13,170 --> 00:02:15,890 And here now am I to the inside of this method. 37 00:02:15,900 --> 00:02:22,270 So inside of this method I created an object of type husht RL connection. 38 00:02:22,410 --> 00:02:27,750 Ok this is very important because we want to connect to the iTunes Web service we need to create an 39 00:02:27,780 --> 00:02:37,130 object of type husht connection and I assign the value null to this object here and in line 23. 40 00:02:37,290 --> 00:02:43,920 I created an object of type input stream as you can see here the data type of this object is input stream 41 00:02:44,370 --> 00:02:47,510 and then I assign the value gnarl to this object. 42 00:02:47,540 --> 00:02:53,060 OK because we want to actually get the data and get those eight and put into our application. 43 00:02:53,160 --> 00:02:56,510 We need to create an object of type input stream. 44 00:02:56,550 --> 00:03:03,000 So here I have this try block here as you can see this try catch exception here as you can see here. 45 00:03:03,000 --> 00:03:06,390 So first of all I created this try block. 46 00:03:06,420 --> 00:03:07,260 So try. 47 00:03:07,410 --> 00:03:13,400 And now inside the curly braces of this a try here as you can see I have these lines of code. 48 00:03:13,520 --> 00:03:16,200 Ok I have this try block here. 49 00:03:16,470 --> 00:03:18,160 So insight is tripe block. 50 00:03:18,180 --> 00:03:20,040 This is very important. 51 00:03:20,280 --> 00:03:25,080 We have we are actually initialising we are actually adding somebody used to these husht that if you 52 00:03:25,080 --> 00:03:29,580 have a connection I am assigning a value to this hash to be a connection here. 53 00:03:29,590 --> 00:03:30,900 11:27. 54 00:03:30,900 --> 00:03:37,580 So I referred to the name of this husht that you are a connection object assignment operator. 55 00:03:37,650 --> 00:03:43,850 So as you can see here I am actually casting this value here to a husht to be your connection object. 56 00:03:43,860 --> 00:03:45,090 So I put this value here. 57 00:03:45,140 --> 00:03:50,430 It is the name of the class I should have your connection inside the practices in order to recast this 58 00:03:50,430 --> 00:03:54,720 value here to a husht you are a connection object. 59 00:03:54,780 --> 00:04:00,750 So here as you can see inside the Prentice's here I actually say the prentices I am actually creating 60 00:04:00,840 --> 00:04:02,560 an object new. 61 00:04:02,680 --> 00:04:06,960 You all as you can see here I am creating an object of type u r l. 62 00:04:07,100 --> 00:04:10,980 OK this is out of class and I am creating an object of type. 63 00:04:11,070 --> 00:04:14,630 You are a class and inside Apprentice's of this you are all here. 64 00:04:14,690 --> 00:04:16,070 This is the constructor of this. 65 00:04:16,130 --> 00:04:18,770 You are in a class right inside Apprentice's. 66 00:04:18,930 --> 00:04:21,910 I referred to the name of the base you are here. 67 00:04:22,110 --> 00:04:22,650 OK. 68 00:04:22,650 --> 00:04:26,850 So the base you are in is the you are at that all you want to actually get the data of the Michael Jackson 69 00:04:26,930 --> 00:04:27,230 right. 70 00:04:27,240 --> 00:04:28,480 As you can see here. 71 00:04:28,590 --> 00:04:33,530 So here I actually created an object of type u r l and I passed this u r l. 72 00:04:33,540 --> 00:04:38,450 This is actually a string value OK to this constructor of this class. 73 00:04:38,460 --> 00:04:40,730 So now I have a U R L object. 74 00:04:40,740 --> 00:04:41,350 OK. 75 00:04:41,750 --> 00:04:46,620 And now as you can see I use this data notation here on this object. 76 00:04:46,620 --> 00:04:52,110 So here as you can see I'm just creating this object without assigning this object to evaluate it to 77 00:04:52,130 --> 00:04:52,730 evaluate it. 78 00:04:52,750 --> 00:04:54,910 OK this is possible in Java. 79 00:04:55,020 --> 00:05:00,580 I'm just creating this object and here I use this notation so that connection. 80 00:05:00,610 --> 00:05:07,210 So this is actually an instance it inside the outer class so here we are we have a you are an object 81 00:05:08,020 --> 00:05:09,080 and this is the method. 82 00:05:09,100 --> 00:05:13,270 This is actually an instance method inside the you are a class open connection. 83 00:05:13,270 --> 00:05:16,520 So I am calling this open connection method and this you are in. 84 00:05:16,570 --> 00:05:21,630 So this means that it's going to actually open the connection that that is related to this. 85 00:05:21,730 --> 00:05:22,780 You are here. 86 00:05:23,010 --> 00:05:23,480 OK. 87 00:05:23,560 --> 00:05:28,320 And it's going to actually cast this value to a real connection object. 88 00:05:28,420 --> 00:05:28,980 OK. 89 00:05:29,170 --> 00:05:35,920 I actually assigned this value to this has to be your last connection and then again in line 28 I referred 90 00:05:36,010 --> 00:05:41,490 to the name of this has to be your connection object that set request method gets. 91 00:05:41,620 --> 00:05:46,830 So because we want to actually get the data from the Internet the said request if must be good with 92 00:05:46,840 --> 00:05:51,700 capital be capitalized to get as you can see here G.T. get. 93 00:05:51,910 --> 00:05:57,190 This is very important and disvalue must be inside double quotes because we want to get the data from 94 00:05:57,190 --> 00:05:57,680 the Internet. 95 00:05:57,700 --> 00:05:58,350 OK. 96 00:05:58,720 --> 00:06:05,140 And in line 29 as you can see husht it'll be your connection that said to input through and husht it 97 00:06:05,140 --> 00:06:07,670 to be your own connection that's set to output. 98 00:06:07,900 --> 00:06:16,060 So let's actually go to the Android documentation in order to see the docs of this has to be a collection 99 00:06:16,060 --> 00:06:16,930 class. 100 00:06:16,930 --> 00:06:19,020 So let's open our Web browser. 101 00:06:19,210 --> 00:06:24,880 So as you can see here this is actually the Android documentation so it is in the search bar here. 102 00:06:24,910 --> 00:06:32,980 I can actually search for husht DTP you RL connection class that is inside of the dot dot dot net package. 103 00:06:32,980 --> 00:06:38,200 So I just need to click on this here and rapee ice and then it's going to actually guide us to this 104 00:06:38,200 --> 00:06:40,520 page husht you all connection. 105 00:06:40,900 --> 00:06:44,060 And this class is actually an abstract class public. 106 00:06:44,350 --> 00:06:49,200 And this class actually extends from this RL connection class as you can see here. 107 00:06:49,480 --> 00:06:55,640 So if you have some descriptions here or you are a connection with support for husht TTP specific features. 108 00:06:55,860 --> 00:06:56,490 OK. 109 00:06:56,800 --> 00:07:03,820 Users of this class follow up pattern obtain a new husht TTP your collection by calling you Arel that 110 00:07:03,880 --> 00:07:08,200 open collection and casting the result to husht to put you on a collection. 111 00:07:08,350 --> 00:07:12,020 So that's that's that's exactly what we did here. 112 00:07:12,210 --> 00:07:13,190 OK. 113 00:07:13,900 --> 00:07:19,120 And then are prepared to request to primary the primary property of a request. 114 00:07:19,120 --> 00:07:20,020 Is it you or I. 115 00:07:20,080 --> 00:07:20,680 OK. 116 00:07:20,830 --> 00:07:27,810 Request headers may also include meta data such as credentials preferred content types and such cookies. 117 00:07:27,820 --> 00:07:28,570 OK. 118 00:07:28,990 --> 00:07:30,890 And these are some other descriptions. 119 00:07:31,120 --> 00:07:35,830 And as you can see here we have this response handling husht you are a connection. 120 00:07:35,830 --> 00:07:38,780 We'll follow up to five husht TTP directs. 121 00:07:38,950 --> 00:07:43,060 It will follow a directs from one origin search and other. 122 00:07:43,060 --> 00:07:49,480 This implementation does not follow redirects from husht TTP as to how she T-P or vice versa. 123 00:07:49,750 --> 00:07:53,730 If the husht response indicates that an error occurred. 124 00:07:53,920 --> 00:07:56,640 Get input stream and are no exception. 125 00:07:56,890 --> 00:08:00,450 Use get error is thrain to read the error response. 126 00:08:00,460 --> 00:08:08,370 The headers can be read in the normal way using the Get header fields and have performance OK. 127 00:08:08,530 --> 00:08:15,750 Handling network seinen as I can see here GTP of integration and some other descriptions. 128 00:08:15,820 --> 00:08:18,010 But for now we want to actually look at them effets. 129 00:08:18,190 --> 00:08:21,700 And now let's scroll down and here this is really important. 130 00:08:21,820 --> 00:08:23,370 Public methods. 131 00:08:23,500 --> 00:08:29,980 So as you can see here we have disconnect indicates that other requests to the server are unlikely in 132 00:08:29,980 --> 00:08:31,370 the near future. 133 00:08:31,390 --> 00:08:37,120 We have good Airstream returns the airstream if the connection failed but the server sent useful data 134 00:08:37,150 --> 00:08:37,950 nonetheless. 135 00:08:38,170 --> 00:08:42,480 As you can see here and as you can see we have some other methods. 136 00:08:42,820 --> 00:08:50,080 Good header field get header field DATE get instance followed redirects So it's important to actually 137 00:08:50,080 --> 00:08:53,230 look at these methods and read the descriptions of these. 138 00:08:53,260 --> 00:09:00,620 If it's OK and make sure that you actually read these descriptions OK this is really important. 139 00:09:00,670 --> 00:09:06,250 And as you can see here we have this search request Meffert set them at for the request one of good 140 00:09:06,280 --> 00:09:08,910 post head options put delete trace. 141 00:09:08,920 --> 00:09:12,330 So we use this get in order to get the data from the Internet. 142 00:09:12,340 --> 00:09:15,950 So now let's actually go back to our Android studio. 143 00:09:16,270 --> 00:09:18,710 So as you can see here we have this Misfit's set. 144 00:09:18,720 --> 00:09:23,490 Request Meffert is good because we want to get the entire information from the server. 145 00:09:23,800 --> 00:09:26,990 And here you are the connection that soote to input. 146 00:09:27,020 --> 00:09:34,240 True so because we want to actually get the data from the Internet and put that data put those information 147 00:09:34,450 --> 00:09:39,260 into our application we need to set this Meffert true set to input true. 148 00:09:39,280 --> 00:09:43,280 This is very important and inline filthy look at this line of code here. 149 00:09:43,390 --> 00:09:47,380 Hush GTP you Aurel connection that set to output true. 150 00:09:47,420 --> 00:09:50,850 OK this if it is actually for outputting data. 151 00:09:50,880 --> 00:09:53,750 As for actually posting data to the Internet. 152 00:09:53,770 --> 00:09:58,660 For example an application may want to actually upload some information to the server or post or post 153 00:09:58,770 --> 00:10:03,420 something to the Internet this Smurfette to output does that job for us. 154 00:10:03,420 --> 00:10:04,760 We don't need the Smurfette here. 155 00:10:04,770 --> 00:10:08,380 I'll just put that here in order to show you what this method does. 156 00:10:08,490 --> 00:10:12,260 We just want to get information from the Internet and put that in into our application. 157 00:10:12,360 --> 00:10:12,890 OK. 158 00:10:12,990 --> 00:10:17,790 We just live this one actually uploading or posting some data into the Internet. 159 00:10:17,790 --> 00:10:22,800 So we don't need this method here because we just want to get the data from the Internet and put that 160 00:10:22,800 --> 00:10:25,510 data into an application and show to the user. 161 00:10:25,620 --> 00:10:29,610 So we just we can't actually comment out this line of code here. 162 00:10:29,610 --> 00:10:31,970 I just wanted to show you what this Mivart does. 163 00:10:32,400 --> 00:10:37,370 And in line for Steven actually referred to the name of this object husht to be your whole connection 164 00:10:37,380 --> 00:10:38,280 that connect. 165 00:10:38,280 --> 00:10:40,490 So it's going to connect to the Internet. 166 00:10:40,530 --> 00:10:41,280 OK. 167 00:10:41,760 --> 00:10:43,240 This is very important. 168 00:10:43,320 --> 00:10:50,460 So and by the way in the future we will be creating more complex applications that involve Jason Parsees 169 00:10:50,490 --> 00:10:52,520 or posting data to the Internet. 170 00:10:52,530 --> 00:10:57,870 For now this is actually just the basic application in order to show you what is done and how to get 171 00:10:57,870 --> 00:10:59,170 decent data from the Internet. 172 00:10:59,190 --> 00:10:59,810 OK. 173 00:11:00,300 --> 00:11:04,070 So and here as you can see I created a comment. 174 00:11:04,350 --> 00:11:05,820 Let's read the response. 175 00:11:05,820 --> 00:11:10,990 So now that we actually connected to the Internet now we want to actually read the response so in line 176 00:11:11,020 --> 00:11:16,080 44 I created an object of type string buffer in order to read the response. 177 00:11:16,080 --> 00:11:16,520 OK. 178 00:11:16,620 --> 00:11:19,000 So the name of this object is a string buffer. 179 00:11:19,170 --> 00:11:25,030 Assignment operator new string buffer an inline 45 as you can see here. 180 00:11:25,080 --> 00:11:31,080 I referred to the name of this input stream object that I actually created inline to any free input 181 00:11:31,080 --> 00:11:33,840 stream assignment operator husht it. 182 00:11:33,860 --> 00:11:36,460 You are a collection that gets input stream. 183 00:11:36,660 --> 00:11:39,080 So now I want to actually get the input stream from. 184 00:11:39,150 --> 00:11:41,260 How should it be you are a connection object. 185 00:11:41,280 --> 00:11:45,450 This is very important because we want to actually read the data if we want to. 186 00:11:45,450 --> 00:11:49,110 We need to actually to initialize this input stream object in this way. 187 00:11:49,240 --> 00:11:49,800 OK. 188 00:11:50,040 --> 00:11:58,060 And then here in line for 86 I actually created an object of type buffer where the reader is slime and 189 00:11:58,080 --> 00:11:59,990 the name of this object is buffered. 190 00:12:00,120 --> 00:12:00,650 OK. 191 00:12:00,810 --> 00:12:07,570 Assignment operator and as you can see here I am initializing this object new Bufford reader at inside 192 00:12:07,570 --> 00:12:13,350 the prentices of these are constructed as you can see here new input stream B that I actually created 193 00:12:13,410 --> 00:12:19,860 an object of type in put simply there and then I passed this input strip object to this in with string 194 00:12:19,860 --> 00:12:20,590 reader here. 195 00:12:20,700 --> 00:12:24,410 OK this is very important because we want to actually read the data from the Internet. 196 00:12:24,420 --> 00:12:27,180 We need to create an object of type buffer every day. 197 00:12:27,180 --> 00:12:31,860 So let's actually open our Android documentation and here as you can see in the search search bar I 198 00:12:31,860 --> 00:12:38,930 can search for Barford buffer and reader class offered reader as you can see here inside the jobs that 199 00:12:38,960 --> 00:12:46,930 are your package and as you can see here it says read text from a character input stream baffling characters 200 00:12:47,140 --> 00:12:51,820 so as to provide for the efficient reading of characters arrows and lines. 201 00:12:51,820 --> 00:12:54,620 So let's go to our Andrex studio. 202 00:12:54,620 --> 00:12:59,860 So here I created an object of type Bufford reader assignment operator new Bufford reader and as you 203 00:12:59,860 --> 00:13:06,310 can see here I am actually creating an object of type input stream reader and I pass this input stream 204 00:13:06,370 --> 00:13:08,090 object to this input stream. 205 00:13:08,090 --> 00:13:08,870 Reader here. 206 00:13:08,890 --> 00:13:09,500 OK. 207 00:13:09,970 --> 00:13:11,100 And inline 47. 208 00:13:11,110 --> 00:13:18,070 I created an object of type string and I assign the value null to this object and the name of this object 209 00:13:18,070 --> 00:13:18,690 is a line. 210 00:13:18,780 --> 00:13:21,630 OK so I want to read the data line by line. 211 00:13:21,820 --> 00:13:29,320 So here I created this while actually while loop here while as you can see and again inside Apprentice's 212 00:13:29,530 --> 00:13:35,060 as you can see line I refer to this line here is string valuable assignment operator. 213 00:13:35,080 --> 00:13:40,210 So here you refer to the next to the name of this Spofford written object that read the line so it can 214 00:13:40,210 --> 00:13:42,560 actually read the data line by line. 215 00:13:42,610 --> 00:13:45,070 OK buffer every bit of that read line. 216 00:13:45,370 --> 00:13:48,880 And if this piece of code here is not equal to null. 217 00:13:49,030 --> 00:13:49,600 OK. 218 00:13:49,840 --> 00:13:53,940 If those information is going to be assigned to this line it's valuable. 219 00:13:53,950 --> 00:14:00,370 And if this piece of code here as you can see here is not equal to nonne and this means that we successfully 220 00:14:00,370 --> 00:14:06,490 got the data from the internet and inside the curly braces here then it's going to execute this line 221 00:14:06,490 --> 00:14:07,960 of what you're saying buffer. 222 00:14:08,110 --> 00:14:13,110 So here I referred to the name of this object string buffer that append. 223 00:14:13,470 --> 00:14:14,170 OK. 224 00:14:14,280 --> 00:14:15,850 Line as you can see here. 225 00:14:15,850 --> 00:14:22,430 So here we are actually assigning this value line by line to this line string value is invaluable. 226 00:14:22,450 --> 00:14:30,580 So line plus this is actually a newline character so we can actually delete this backward slash are 227 00:14:30,580 --> 00:14:31,390 here. 228 00:14:31,780 --> 00:14:32,320 OK. 229 00:14:32,500 --> 00:14:39,520 And back forth slash art is actually our carriage return which means that the cursor should move to 230 00:14:39,560 --> 00:14:41,020 the left leftmost column. 231 00:14:41,050 --> 00:14:41,440 OK. 232 00:14:41,530 --> 00:14:45,820 But this are back for a slash and it's actually a newline character. 233 00:14:45,910 --> 00:14:48,400 OK so we just need this character here. 234 00:14:48,420 --> 00:14:51,060 It can actually move the cursor to the next line. 235 00:14:51,160 --> 00:14:51,810 OK. 236 00:14:52,150 --> 00:14:58,810 So we just put this slash and here and now we are actually appending this value to the string buffer 237 00:14:59,050 --> 00:14:59,790 object. 238 00:14:59,950 --> 00:15:00,610 OK. 239 00:15:00,930 --> 00:15:04,330 And in line 43 we need to close this impled stream here. 240 00:15:04,330 --> 00:15:10,650 So input stream that close and in inline 44 as you can see here again we need to disconnect is how shitty 241 00:15:10,650 --> 00:15:12,520 your whole connection after getting the data. 242 00:15:12,530 --> 00:15:17,530 OK we need to close them and disconnected but how should it be you are a connection that disconnect. 243 00:15:17,530 --> 00:15:22,960 And we are returning this string buffer object so return String buffer that to a string. 244 00:15:22,990 --> 00:15:25,670 So remember this MF at here get iTunes stuff. 245 00:15:25,660 --> 00:15:29,100 Data is actually returning a value of type string. 246 00:15:29,110 --> 00:15:31,080 The return type of this Meffert is strange. 247 00:15:31,210 --> 00:15:36,730 So if you need to return the string value of the string above an object string buffer. 248 00:15:36,730 --> 00:15:38,630 That is strange. 249 00:15:38,680 --> 00:15:41,380 And we have a catch up block here. 250 00:15:41,380 --> 00:15:46,660 So in case that we cannot actually connect to the Internet or we don't have any internet connection 251 00:15:47,050 --> 00:15:53,090 it's going to catch the errors and then it's going to output the error to the console to the larg t 252 00:15:53,410 --> 00:15:54,660 that prints that trace. 253 00:15:54,670 --> 00:15:58,620 As you can see here and we have this finally block here. 254 00:15:58,690 --> 00:15:59,990 So this is very important. 255 00:16:00,040 --> 00:16:06,600 So if the application fails to execute these lines of code here or if the application fails to execute 256 00:16:06,600 --> 00:16:11,740 the try block here or the catch statement is going to finally execute these lines of code by putting 257 00:16:11,740 --> 00:16:19,000 this finally block here if are 100 percent sure that it can actually execute these lines of code inside 258 00:16:19,060 --> 00:16:22,210 is finally Blache so try and put in that close. 259 00:16:22,210 --> 00:16:27,180 So here inside this finally block we have this try catch block here. 260 00:16:27,430 --> 00:16:30,060 And again we are actually closing this input stream. 261 00:16:30,190 --> 00:16:35,950 So if the if the application fails to execute these lines of code here as you can see it's going to 262 00:16:35,950 --> 00:16:37,790 finally execute these things of course. 263 00:16:37,810 --> 00:16:43,400 And this means that we are we are now 100 percent sure that it's going to close the input stream. 264 00:16:43,750 --> 00:16:46,340 And how should we be sure that disconnect. 265 00:16:46,390 --> 00:16:50,300 OK so these lines of code are going to be executed anyway. 266 00:16:50,350 --> 00:16:55,910 So this is really important that you actually close the input stream and disconnect the connection. 267 00:16:56,050 --> 00:16:56,610 OK. 268 00:16:57,010 --> 00:17:02,150 And we have this catch block again in order to catch the errors and put them in the log. 269 00:17:02,380 --> 00:17:08,410 And yet at the end if the flow of the application returns to this line of code here as you can see it's 270 00:17:08,410 --> 00:17:14,670 going to return not what if the application succeeds to actually get the information from the Internet 271 00:17:14,670 --> 00:17:18,670 is going to actually return this string buffer the twisting value. 272 00:17:18,760 --> 00:17:22,110 So now let's actually paste in another Meffert. 273 00:17:22,120 --> 00:17:24,370 In order to download the image from the Internet. 274 00:17:24,370 --> 00:17:31,290 OK so remember we are actually getting the art form you are here in our iTunes in adjacent iTunes person 275 00:17:31,300 --> 00:17:35,140 as you can see if you are actually setting the artist view you are there. 276 00:17:35,140 --> 00:17:41,570 So you're getting this artwork here are for Twaddell So if you need to actually create another download 277 00:17:41,570 --> 00:17:43,390 the image from the Internet. 278 00:17:43,430 --> 00:17:48,030 So now I'm going to paste in MF at here and then I'm going to explain to you what's going on here.
