TextView textPrompt;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textPrompt = (TextView)findViewById(R.id.prompt);

if(isInMultiWindowMode()){
textPrompt.setText("onCreate run In Multi Window Mode ");
}else{
textPrompt.setText("onCreate run NOT In Multi Window Mode ");
}
}

@Override

if(isInMultiWindowMode){
textPrompt.setText("It is In Multi Window Mode ");
}else{
textPrompt.setText("It is NOT In Multi Window Mode ");
}
}
}
