How to restart activity with singleInstance activity from other activity

Question

How to replace or restart activity with singleinstance from another activity.

i have two activity, ActivityA and ActivityB.

in manifest:

 <activity
    android:name=".ActivityA"
    android:label="@string/activityA"
    android:launchMode="singleInstance" >
</activity>
<activity
    android:name=".ActivityB"
    android:label="@string/activityB" />

My question, how to restart ActivityA from method in ActivityB. Mycode no in ActivityB is:

class ActivityB extends Activity{

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Button rButton = (Button) findViewById(R.id.restart);
        rButton.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                 restartActivityA();
            }
        });
    }

    public void restartActivityA() {
       Intent intent = new Intent(this, ActivityA.class);
       intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK|Intent.FLAG_ACTIVITY_CLEAR_TOP);
       startActivity(intent);
       this.finish();
    }
}

If i click the button, so not restart.

Thanks.

are you getting any error when running this code by start first activity as `startActivity(intent);` ? — ρяσѕρєя K, Jan 12 '13 at 12:51
@HaicalRams how do you calling `ActivityB` from `ActivityA`? — Pratik Sharma, Jan 12 '13 at 13:25
Intent intent = new Intent(this, ActivityB.class); startActivity(intent); — Dave Jackson, Jan 12 '13 at 13:36

Try to add this to your ActivityA :

    @Override
    protected void onNewIntent(Intent intent) 
    {
        super.onNewIntent(intent);           
    }

EDIT:

Call ActivityB like this :

Intent intent = new Intent(this, ActivityB.class); 
startActivity(intent);
finish();

Thanks.

try this may be it will help.

Intent intent = getActivity().getIntent();//it will return the intent for current activity

I have Log.d("MyLog","Activitystart"); in onCreate ActivityA to see what ActivityA start or not. – Dave Jackson Jan 12 '13 at 13:38
