Android編程：GCMIntentService卡在WakeLock

我已經閱讀了關於在這裏找到的WakeLock的各種解決方案，比如在AndroidManifest.xml中添加Permission以及確保GCMIntentService的構造函數設置爲public。Android編程：GCMIntentService卡在WakeLock

然而，我的代碼還停留在「獲取激活鎖定」

完全相同的代碼工作seperately作爲一個單獨的Android應用程序。

我只是遇到這個錯誤後，我把它集成到我的主要應用程序。

以下是我對GCM意圖服務代碼：

代碼

最後但並非最不重要的，從logcat的

Registering app com.mp2012.ieatishootipostanalyzer of senders 74463753470 
onReceive: com.google.android.com.c2dm.intent.REGISTRATION 
GCM IntentService class: com.mp2012.ieatishootipostanalyzer.GCMIntentService 
Acquiring wakelock

和它掛....

由於錯誤！

保留主包裝中的所有GCM相關類別，即您在其中呼叫gcm註冊。像你的項目包名稱com.mp2012.ieatishootipostanalyzer一樣。

非常感謝！不能相信我的解決方案非常簡單，我花了整整一週的時間！ :) – user1859057

同樣在這裏:)謝謝隊友。 –

想給多個投票支持:) – Nizam

可能出現這樣的情況：主包下有很多包，並且GCM代碼需要放在另一個包中。例如com.mp2012.ieatishootipostanalyzer.notification。這也可以完成，但你需要編輯谷歌雲消息系統提供的GCM代碼。這是在GCMBroadcastReceiver：

protected String getGCMIntentServiceClassName(Context context) 
{ 
    String className = context.getPackageName() +".notification"+DEFAULT_INTENT_SERVICE_CLASS_NAME; 

    return className; 
}

該系統將工作。

因爲我正在修改build.gradle中的_applicationId_，而不是調用'getPackageName（）'，所以我必須對包名進行硬編碼，因爲前者返回_applicationId_而不是包名。沒有辦法以這種方式找到我的_GCMIntentService_類。 –
