How to finish an android application?

Question

I need to finish an android application. For that i wrote

@Override public void onBackPressed() {     AlertDialog.Builder builder = new AlertDialog.Builder(this);     builder.setMessage("Are you sure You want to exit")         .setCancelable(false)         .setPositiveButton("YES"),         new DialogInterface.OnClickListener() {             // On             // clicking             // "Yes"             // button              public void onClick(DialogInterface dialog,int id) {                 System.out.println(" onClick ");                 closeApplication(); // Close Application method called             }         })         .setNegativeButton("NO"),         new DialogInterface.OnClickListener() {             // On             // clicking             // "No"             // button             public void onClick(DialogInterface dialog,int id) {                 dialog.cancel();             }         });          AlertDialog alert = builder.create();         alert.show();     }      private void closeApplication() {         System.out.println("closeApplication ");         this.finish();     } } 

But if any activity is not finished in the application, when i tried to exit the application that activity is finished first and the application is not exiting.. i tried 2 times to exit this application... How i can finish all the activities in an application when i need to exit... or is there any way to finish the entire application

Answer 1

To close application just call:

android.os.Process.killProcess(android.os.Process.myPid()); 

Otherwise due-to specific life-cycling of Android activities you can't be sure that application is closed/killed.

Answer 2

whenever you are starting a new activity use

myintent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); startActivity(myintent); 

and in manifest file mention that activity as

<activity android:name=".<Activity Name>" >         <intent-filter>         <action android:name="android.intent.action.VIEW"/>      <category android:name="android.intent.category.DEFAULT" />      </intent-filter>        </activity>
