Use android:launchMode="singleTask" for your MainActivity in AndroidManifest.xml.

Which will keep only one instance of MainActivity if launched again this activity will come to top of the stack. And Use this code

Intent intent = new Intent( MainActvity2.this, MyActivity.class );
intent.setFlags( Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP );
current_activity.startActivity( intent );

This is why Android maintains states of each activity in a Stack, that's why when you will press that Back-button, you just have to clear all previous activities from the stack and then open MainActivity

Just you have to set flags before starting intent:

Intent intent = new Intent(MainActivity2.this,MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
finish();

call finish method after startIntent

something like this:

Intent intent = new Intent(MainActivity2.this,MainActivity.class);
startIntent(intent);
finish();

and put finish method in your activity

@Override
public void finish() {
    super.finish();
}

its very simple.. use finish();

Intent intent = new Intent(MainActivity2.this,MainActivity.class);
startIntent(intent);
finish();

bcz u create multi activity in mainActivity2. so u have to destroy your activity before u go to mainActivty.

otherwise when u open new many in mainactivity2. that time use finish.. bcz u must have to destroy first your mainActivity2.

if you not understand my answer then just post your whole code... i will edit...
