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.

Answer1:

Try to add this to your ActivityA :

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

<strong>EDIT:</strong>

Call ActivityB like this :

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

Thanks.

Answer2:

try this may be it will help.

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

hope this helps.
