Android权限拒绝:广播意图

Question

我真的不知道出了什么问题,但我的if小部件是由系统更新的"APPWIDGET_UPDATE"它抛出以下异常.我尝试了几件事,导出接收器(真/假),我在模拟器和真实手机上试过它,但它是一样的.我添加了几个intent-filters,但它没有用.

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只是声明,因为我试图消除可能性,但是在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) {

        }   
}

如果你能看看,我很感激...

你的问题出在什么地方你的Java代码,您正试图发送的android.appwidget.action.APPWIDGET_UPDATE广播.这是由操作系统广播,而不是由应用程序广播,这就是它的意义Permission Denial所在.
