Android Java-無法銷毀活動：IndexOutOfBoundsException

Question

每當我關閉應用程序時，都會出現以下錯誤：

接觸我編寫的代碼的唯一部分是：

CompanyNavigation活動：

@Override
public void onDestroy() {
    super.onDestroy();
    getSpecificImpOfGenericPresenter().closeRealm();
}

及其超類GenericMvpActivity：

@Override
public void onDestroy() {
    super.onDestroy();
    //Unbind Butterknife bindings
    if(mUnbinder!=null) {
        mUnbinder.unbind();
    }
}

通過查看stacktrace，我可以看到它與片段相關，但這在Android代碼中。 該CompanyNavigationActivity有時確實包含許多片段， 但是無論是否創建它們都會發生錯誤 。

關於原因是什么？

編輯1

presenter類中的closeRealm方法僅刪除監聽器並關閉realm的presenters實例。

public void closeRealm() {
    this.mRealmDatabase.getInstance().removeAllChangeListeners();
    this.mRealmDatabase.close();
}

編輯2

經過進一步測試，似乎如果我在CompanyNavigationActivity中的viewpager中創建片段， 則不會發生此錯誤。 它似乎僅在活動中不存在任何片段時發生。

編輯3

我將其范圍縮小為一種特定的方法，該方法正在啟動前台服務。 更具體地說，startService調用。

     /**
     * If foreground location service is not running, start it
     */
    private void startLocationService() {
        if (!ForegroundLocationService.IS_SERVICE_RUNNING) {
            Intent service = new Intent(getSpecificImpOfGenericView().getApplicationContext(), ForegroundLocationService.class);
            service.setAction(ServiceConstants.ACTION.STARTFOREGROUND_ACTION);
            ForegroundLocationService.IS_SERVICE_RUNNING = true;
            getSpecificImpOfGenericView().getApplicationContext().startService(service);
        }
    }

當然，前台請求應該作為單獨的服務保留在前台中，並且不影響啟動它們的活動的破壞嗎？

Answer 1

您應該在super.onDestroy();之前完成所有工作super.onDestroy(); 在銷毀實例特定資源可能依賴的超類資源之前，請先銷毀實例特定資源。
