我真的不知道出了什么问题,但是我的如果小部件是由系统通过“APPWIDGET_UPDATE”更新的,它会引发以下异常。我尝试了几件事,导出接收器(真/假),我在模拟器和真机上尝试过,但它是一样的。我添加了几个intent-filters,但它没有工作。

11-06 20:10:10.279: W/ActivityManager(61): Permission denied: checkComponentPermission() reqUid=1000
11-06 20:10:10.279: W/ActivityManager(61): Permission Denial: broadcasting Intent { act=android.appwidget.action.APPWIDGET_UPDATE (has extras) } from com.ency.easychange (pid=1196, uid=10034) requires null due to receiver com.android.settings/com.android.settings.widget.SettingsAppWidgetProvider

我的 AppWidgetProvider 仅被声明,因为我试图消除可能性,但在ExchangeRateWidgetProvider.onReceive()调用之前抛出异常。

public class ExchangeRateWidgetProvider extends AppWidgetProvider {
    public static final String tag = "ExchangeRateWidgetProvider"; 

        @Override
        public void onUpdate(Context context, AppWidgetManager appWidgetManager,
                int[] appWidgetIds) {

        }   
}

我的清单:

            <action android:name="android.appwidget.action.APPWIDGET_CONFIGURE"/>
        </intent-filter>
    </activity>

</application>

如果你能看一下,我很感激......

您的问题出在您尝试发送android.appwidget.action.APPWIDGET_UPDATE广播的 Java 代码中。那是由操作系统而不是应用程序广播的,这就是它的意义Permission Denial所在。
