Unable to close all activities on android eclipse

Question

Assume i have four classes.Each class is having a button to do screen switching from one page to another page,well its working fine.But now im trying to close all the activi

Answer 1

I would insist to create an BaseActivity with a BroadCastReceiver that will notify when you want to finish all the Activities and extend all the Activity classes with this BaseActivity,

public static final String ACTION_FINISH = "ACTION_FINISH";
public class BaseActivity extends Activity {

public void onCreate(Bundle bundle, int resourceId) {
    super.onCreate(bundle);
    registerReceiver(finishActivitiesReceiver, 
                                          new IntentFilter(ACTION_FINISH));
}

protected void onDestroy() {
    super.onDestroy();
    unregisterReceiver(finishActivitiesReceiver);
}

BroadcastReceiver finishActivitiesReceiver = new BroadcastReceiver() {

        @Override
        public void onReceive(Context context, Intent intent) {
            finish();
        }
    };
}

Then you can just send BroadCast when you want to close all Activities using

sendBroadcast(new Intent(BaseActivity.ACTION_FINISH));
