我有一個小部件，它的工作原理時，它不會......當它不！具體來說，如果我重新啓動手機並點擊小部件，東西就會發生。也許有一段時間，我可以繼續點擊小部件，一切正常。但最終（也許一個小時？）它只是停止工作。從logcat中，我的代碼根本沒有被執行，所以它就像從來沒有發送到我的應用程序。我的思考過程是，因爲在發生這種情況時，我的代碼都不會執行，所以問題必須在清單中，或者其他我不知道的東西。Android小部件不執行...有時
下面是logcat的工作原理。從這裏最後一行來自於我的代碼：

我沒有看到任何突出的問題。
下面是該widgetProvider清單部分：
<receiver android:name="com.skipmorrow.phca.PhcaAppWidgetProvider" >
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
<action android:name="com.skipmorrow.phca.PhcaAppWidgetProvider.WIDGET_CLICKED" />
<action android:name="com.skipmorrow.phca.PhcaAppWidgetProvider.VARIABLE_UPDATED" />
<action android:name="android.appwidget.action.APPWIDGET_DELETED"/>
<action android:name="CORRECT_PIN_ENTERED_FOR_WIDGET"/>
</intent-filter>
<meta-data android:name="android.appwidget.provider"
android:resource="@xml/phca_widget_info" />
</receiver>
順便說一句，我使用的是三星Galaxy S3運行ICS。我的應用程序有minSdkVersion =「8」和targetSdkVersion =「8」
週末沒有答案，但我做了一些故障排除。我仍然有問題，但我確實有其他信息。
小部件會從提供小部件文本的後臺服務中更新。但是，小部件並不總是按照他們點擊時應該做的事情做。換句話說，即使點擊沒有得到正確處理，我仍然可以更新小部件中的文本，所以小部件不會完全打破，如果有幫助的話。這似乎也是點擊響應來來去去。也就是說，重新啓動後，點擊似乎可以工作一段時間，然後可能會停止工作一段時間，然後再次開始工作。我的AppWidgetProvider重寫onUpdate，onEnabled，onDeleted，onDisabled和onReceive方法，但我只使用onReceive方法並手動跟蹤每個意圖。 onReceive方法的第一行寫入日誌，所以我可以看到當點擊不起作用時，根本沒有代碼在我的AppWidgetProvider中執行，所以我仍然不認爲問題出現在我的AppWidgetProvider中，並且可能在我的清單中？
難道這是一個權限問題？還是我沒有正確註冊接收器？
