「onSaveInstanceState後無法執行此操作」刪除所有片段

我試圖刪除的onStop()中的所有片段，但是會引發異常：Can not perform this action after onSaveInstanceState。我怎麼能這樣做？「onSaveInstanceState後無法執行此操作」刪除所有片段

我正在試着這個。

我有這個問題，如果您在調用SaveInstaceState後調用getFragmentManager（），將會出現錯誤。

變化

@Override 
protected void onStop() { 
    PushControl.setIsVisible(false); 
    removeAllFrags(); 
    super.onStop(); 
}

到

@Override 
protected void onPause() { 
    PushControl.setIsVisible(false); 
    removeAllFrags(); 
    super.onPause(); 
}

請記住，根據有關的onSaveInstanceState的文檔「如果叫，會的onStop（）之前發生的這個方法。沒有關於是否會發生這保證在onPause（）之前或之後「。 http://developer.android.com/reference/android/app/Activity.html#onSaveInstanceState(android.os.Bundle） –

我改成了'fm.popBackStackImmediate（）'。非常感謝。 – FernandoPaiva

嘗試刪除

finish();

從removeAllFrags()方法;
