Question

我在Google Play中有一款Android应用。在开发者控制台中，我看到应用程序的onCreate of MainActivity中发生了很多崩溃。

我自己从未见过这种崩溃。仅限Google Play。

我真的不知道问题是什么，或者在哪个方向上搜索解决方案。

  at android.app.Instrumentation.callActivityOnCreate (Instrumentation.java:1126)
  at android.app.ActivityThread.performLaunchActivity (ActivityThread.java:2927)

MainActivity是应用程序的主要功能，它显示了一堆不同的片段。它扩展了LanguageActivity。 LanguageActivity扩展了android.support.v7.app.AppCompatActivity

MainActivity的onCreate看起来像

at be.gps.android73.activities.LanguageActivity.onCreate (LanguageActivity.java:23)
at be.gps.android73.activities.main.MainActivity.onCreate (MainActivity.java:117)

LanguageActivity看起来像

@Override
protected void onCreate(final Bundle savedInstanceState)
{
   super.onCreate(savedInstanceState); //this is line 117 from the stacktrace
   ...

任何可能导致此问题的线索或提示？
