Question

I am working with Android application to show network error.

NetErrorPage.java

package exp.app;  import android.app.Activity; import android.app.AlertDialog; import android.content.Context; import android.content.DialogInterface; import android.content.Intent; import android.net.ConnectivityManager; import android.net.NetworkInfo; import android.os.Bundle; import android.view.KeyEvent; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button;  public class NetErrorPage extends Activity implements OnClickListener {          @Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.neterrorlayout);         Button reload=(Button)findViewById(R.id.btnReload);         reload.setOnClickListener(this);             showInfoMessageDialog("Please check your network connection","Network Alert");      }      public void onClick(View arg0)                      {             if(isNetworkAvailable())             {                                    Intent myIntent = new Intent((Activity)NetErrorPage.this, MainActivity.class);                    myIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);                               ((Activity)NetErrorPage.this).startActivity(myIntent);                 finish();             }             else                 showInfoMessageDialog("Please check your network connection","Network Alert");     }      public void showInfoMessageDialog(String message,String title)        {         AlertDialog alertDialog = new AlertDialog.Builder(NetErrorPage.this).create();         alertDialog.setTitle("Network Alert");         alertDialog.setMessage(message);         alertDialog.setButton("OK",                 new DialogInterface.OnClickListener() {                     public void onClick(DialogInterface dialog,int which)                      {                            dialog.cancel();                     }                 });                     alertDialog.show();     }   private boolean isNetworkAvailable()     {         NetworkInfo ActiveNetwork;         @SuppressWarnings("unused")         String IsNetworkConnected;         @SuppressWarnings("unused")         String ConnectionType;         ConnectivityManager connectivitymanager;         connectivitymanager=(ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);                 try         {                        ActiveNetwork=connectivitymanager.getActiveNetworkInfo();             ConnectionType=ActiveNetwork.getTypeName();              IsNetworkConnected=String.valueOf(ActiveNetwork.getState());             return true;                                 }         catch(Exception error)         {                 return false;         }     }     }

I have searched more... but i don't have any right idea to clear this.

What i want is, when loading this page, layout should be added and dialog should be shown.

Please help me to clear this error

Note: I have tried this also

@Override     protected void onResume() {     super.onResume();         runOnUiThread(new Runnable() {             public void run() {                 showInfoMessageDialog("Please check your network connection","Network Alert");             }         });      } 

Answer 1

Thank you Guys to give me many suggestions. Finally I got a solution. That is i have started the NetErrorPage intent two times. One time, i have checked the net connection availability and started the intent in page started event. second time, if the page has error, then i have started the intent in OnReceivedError event. So the first time dialog is not closed, before that the second dialog is called. So that i got a error.

Reason for the Error: I have called the showInfoMessageDialog method two times before closing the first one.

Now I have removed the second call and Cleared error :-).
