Go homeActivity with FLAG_ACTIVITY_CLEAR_TOP in android

It sets the FLAG_ACTIVITY_CLEAR_TOP flag on the Intent along with the HomeActivity.  This flag  launches a new instance of the activity if it isn’t currently running, and closes all the activities on top of it.

public static void goHome( Context ctx )
{
    if ( ! ( ctx instanceof HomeActivity ) )
    {
        Intent intent = new Intent( ctx, HomeActivity.class );
        intent.setFlags( Intent.FLAG_ACTIVITY_CLEAR_TOP );
        ctx.startActivity( intent );
    }
}
