Question

我有一个小部件可以在它想要的时候工作......好吧它没有！具体来说，如果我重新启动手机并点击小部件，就会发生类似的情况。也许有一段时间我可以继续点击小部件，一切正常。但最终（也许一小时？）它就停止了工作。从logcat开始，我的代码都没有被执行，所以就像点击从未发送到我的应用程序一样。我的思维过程是因为当这种情况发生时我的代码都没有执行，所以问题必须在清单中，或者是我不知道的其他内容。

这是logcat的工作原理。这里的最后一行来自我的代码：

这是logcat从不起作用的时候。

我没有看到任何突出的问题。

这是widgetProvider的清单部分：

 <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>

是的，我正在使用运行ICS的三星Galaxy S3。我的应用有minSdkVersion =“8”和targetSdkVersion =“8”

周末没有答案，但我做了一些故障排除。我仍有问题，但我确实有其他信息。

小部件确实从提供小部件文本的后台服务更新。但是，当小部件被点击时，小部件并不总是按照它们应该做的那样做。换句话说，即使没有正确处理点击，我仍然可以更新小部件中的文本，因此小部件不会完全被破坏，如果这有帮助的话。似乎点击响应来来去去。也就是说，重启后点击似乎工作了一段时间，然后可能会停止工作一段时间，然后再开始工作。我的AppWidgetProvider会覆盖onUpdate，onEnabled，onDeleted，onDisabled和onReceive方法，但我只使用onReceive方法并手动跟踪每个intent。 onReceive方法的第一行写入日志，所以我可以看到，当点击不起作用时，我的AppWidgetProvider中根本没有代码执行，所以我仍然认为问题不在我的AppWidgetProvider中，可能在我的清单???

这可能是权限问题吗？或者我没有正确注册接收器？

我终于明白了。旋转屏幕后禁用。这就是它似乎随机的原因。我从来没有将两者联系起来这篇文章让我看向正确的方向： Auto Screen Rotation Disabling Widget RemoteView onClick event

Android小部件有时不执行...
