        android:launchMode="singleTop"
        android:configChanges="orientation|keyboardHidden|screenLayout|screenSize" />

and i have declare android:launchMode="singleTop" all activity in android manifest file

Answer 1

android:launchMode="singleTop"

It means if the activity is already there on the top, it won't create an another instance. Instead onNewIntent() of an activity will get called with updated intent as a parameter.

@Override
public void onNewIntent(Intent intent) {
    // Deal with new Intent over here...
}
