    text
    copied!<p>I have 2 applications which are communicating through an AsyncTask. The first application is a Java server, running on my PC. The second application is an Android Client.</p> <p>The server send to the client a message like that :</p> <blockquote> <p>" 1stMember , 2ndMember , 3rdMember , ... , 10thMember "</p> </blockquote> <p>Then, the Client retrieve this message in the innerclass <strong>connectTask</strong> from the client class. But the application is always crashing.</p> <p>This is my client <strong>MainActivity.java</strong> :</p> <pre><code>public class MainActivity extends FragmentActivity { private TCPClient tcpclient; protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // Connect to server - See innerClass connectTask below new connectTask().execute(""); } public class connectTask extends AsyncTask&lt;String, String, TCPClient&gt; { protected TCPClient doInBackground(String... message) { // Creation of TCPClient object... tcpclient=new TCPClient(new TCPClient.OnMessageReceived() { public void messageReceived(String message) { publishProgress(message); /*==&gt; publishProgress receive message, then notify onProgressUpdate*/ } }); tcpclient.runClient(); return null; } protected void onProgressUpdate(String...values) { super.onProgressUpdate(values); showMySelectedValues(values[0].toString()); } } public void showMySelectedValues(String values) { String[]selectedvalues=values.split(","); Log.i("LENGTH OF selectedvalues... : ",""+selectedvalues.length); Toast.makeText(getApplicationContext(),selectedvalues[3],Toast.LENGTH_SHORT).show(); Toast.makeText(getApplicationContext(),selectedvalues[5],Toast.LENGTH_SHORT).show(); } } </code></pre> <p>Before crashing, the application still shows me the toast. <strong>Here is my Logcat :</strong></p> <p><img src="https://i.stack.imgur.com/nc1Pl.png" alt="enter image description here"> </p> <pre><code>12-11 16:09:33.070: D/dalvikvm(11798): GC_FOR_ALLOC freed 5K, 12% free 9455K/10695K, paused 28ms, total 28ms 12-11 16:09:35.914: I/LENGTH OF selectedvalues... :(11798): 12 12-11 16:09:35.945: I/LENGTH OF selectedvalues... :(11798): 12 12-11 16:09:35.953: I/LENGTH OF selectedvalues... :(11798): 12 12-11 16:09:35.976: I/LENGTH OF selectedvalues... :(11798): 1 12-11 16:09:35.976: D/AndroidRuntime(11798): Shutting down VM 12-11 16:09:35.976: W/dalvikvm(11798): threadid=1: thread exiting with uncaught exception (group=0x4104f2a0) 12-11 16:09:35.984: E/AndroidRuntime(11798): FATAL EXCEPTION: main 12-11 16:09:35.984: E/AndroidRuntime(11798): java.lang.ArrayIndexOutOfBoundsException: length=1; index=3 12-11 16:09:35.984: E/AndroidRuntime(11798): at com.fiamm.tcpandroid.MainActivity.showMySelectedValues(MainActivity.java:154) 12-11 16:09:35.984: E/AndroidRuntime(11798): at com.fiamm.tcpandroid.MainActivity$connectTask.onProgressUpdate(MainActivity.java:145) 12-11 16:09:35.984: E/AndroidRuntime(11798): at com.fiamm.tcpandroid.MainActivity$connectTask.onProgressUpdate(MainActivity.java:1) 12-11 16:09:35.984: E/AndroidRuntime(11798): at android.os.AsyncTask$InternalHandler.handleMessage(AsyncTask.java:647) 12-11 16:09:35.984: E/AndroidRuntime(11798): at android.os.Handler.dispatchMessage(Handler.java:99) 12-11 16:09:35.984: E/AndroidRuntime(11798): at android.os.Looper.loop(Looper.java:137) 12-11 16:09:35.984: E/AndroidRuntime(11798): at android.app.ActivityThread.main(ActivityThread.java:4895) 12-11 16:09:35.984: E/AndroidRuntime(11798): at java.lang.reflect.Method.invokeNative(Native Method) 12-11 16:09:35.984: E/AndroidRuntime(11798): at java.lang.reflect.Method.invoke(Method.java:511) 12-11 16:09:35.984: E/AndroidRuntime(11798): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:994) 12-11 16:09:35.984: E/AndroidRuntime(11798): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:761) 12-11 16:09:35.984: E/AndroidRuntime(11798): at dalvik.system.NativeStart.main(Native Method) </code></pre> <p>Here is the <strong>Debuger</strong>: <img src="https://i.stack.imgur.com/WFNTH.png" alt="enter image description here"></p> <p>When I do this in onProgressUpdate(String...values), it is not crashing :</p> <pre><code>protected void onProgressUpdate(String...values) { super.onProgressUpdate(values); Toast.makeText(getApplicationContext(),selectedvalues[3],Toast.LENGTH_SHORT).show(); } </code></pre> <p>But when I <strong>make more than 1 toast</strong>, then the <strong>application is crashing again</strong>.</p> <p>I don't understand what is wrong in my code.
