GCM應用程序在模擬器上正常工作，但在Android設備上崩潰

-2

我開發了一個應用程序並實現了GCM（Google Cloud Messaging），它在模擬器上以及在bluestacks上都能很好地工作，但是當我在設備上運行它時，不幸的是，我無法得到原因。GCM應用程序在模擬器上正常工作，但在Android設備上崩潰

無論是如果您不提供更多詳細信息，請聯繫我們 – Henry

您需要什麼細節，完整的代碼或清單代碼 –

logcat輸出和相關的代碼。 – Henry

我相信這個問題是因爲你沒有在你的清單中定義MainActivity在此基礎上的logcat行：

14:55:27.034: E/AndroidRuntime(25344): Caused by: 
android.content.pm.PackageManager$NameNotFoundException: 
ComponentInfo{com.example.androiddemos/com.example.androiddemos.MainActivity} 01-09

你MainActivity引用作爲parentActivityName但在清單中根本沒有定義：

<activity 
    android:name=".ResultActivity" 
    android:parentActivityName=".MainActivity" > 
    <meta-data 
     android:name="android.support.PARENT_ACTIVITY" 
     android:value=".NotificationActivity" /> 
</activity>

如果你還在使用MainActivity你需要將它添加到清單：

<activity 
    android:name=".MainActivity"> 
</activity>
