使用解析的Android推送在一段時間後停止工作

Question

我正在使用解析在Android上發送目標推送通知。幾次（不眠之夜包括）跟着教程，它完美的作品，但是在某些不可預知的事件，應用程序的Android用戶停止接收通知。在Google Play上更新數小時後，肯定會發生這種情況。

爲了在不上載到Google Play的情況下進行復制，我縮小了範圍，直到從清單更新應用程序的版本號並重新運行而不刪除並重新安裝。但是，在清單中進行簡單的更改會使其再次起作用。然而，該解決方案並不可靠，因爲它會在上傳到生產後幾小時/之後再次停止工作。

我正在使用自定義的ParsePushBroadcastReceiver播放自定義聲音。我正在使用Google Play Services 5進行位置更新。我正在訂閱我在以後的活動中推廣的頻道。有什麼想法可能會導致這樣的問題？下面的代碼粘貼：

     // so add 1 to make it inclusive

UPDATE

這裏是我如何的時刻再現問題。我運行在調試模式下，它工作，然後我更改應用程序的版本號，並導出簽名的應用程序進行生產（無需運行）。我將該已簽名的APK安裝到設備上（刪除後）並且通知停止工作。似乎重寫ParsePushBroadcastReceiver與它無關。如果我刪除並以相同版本號的調試模式重新運行，直到我更改清單中的某些內容（如BroadcastReceiver）後纔會起作用。這是我設法重現它的方式，但通知到達Google Play時（無論如何都會停止工作）（現在再試一次）。我錯過了什麼？

Answer 1

在example implementation是這樣的評論：

// Check if app was updated; if so, it must clear the registration ID 
// since the existing registration ID is not guaranteed to work with 
// the new app version. 

我敢肯定，你遇到了這一點。因此解決方案是在更新後註冊您的應用程序。我想在你的情況下，最好的選擇是看看PACKAGE_REPLACED事件，在那裏你應該再次註冊你的應用程序。請檢查this question以查看它是如何工作的。
