Android Intent not kept in the history stack

If we start an intent but do not push on the history stack, this is pretty easy, we can use the setFlags function and set to FLAG_ACTIVITY_NO_HISTORY.

    Intent intent = new Intent();
    intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
    intent.setClass(this, cpr.class);
    startActivity(intent);

In the current activity, but we don't need to kept in the history stack. we should change the Manifest.xml

<activity android:name='current' android:noHistory='true'>
</activity>
