我的应用程序小部件在升级到 targetSDk 到 28 后停止工作。
- 它可以在旧的 Targetsdk 设备上完美运行。
我收到以下错误:
W/BroadcastQueue: Background execution not allowed: receiving Intent { act=ch.corten.aha.worldclock.WIDGET_DATA_CHANGED flg=0x10 } to ch.corten.aha.worldclock/.WorldClockWidgetProvider
W/BroadcastQueue: Background execution not allowed: receiving Intent { act=ch.corten.aha.worldclock.WIDGET_DATA_CHANGED flg=0x10 } to ch.corten.aha.worldclock/.WeatherWidgetProvider
androidmanifest.xml文件内容如下-
<!-- clock widget -->
<receiver

android:exported="false"
android:label="@string/clock_widget_name" >
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />

</receiver>
和我的恢复类代码(
@Override
public void onReceive(Context context, Intent intent) {
super.onReceive(context, intent);
if (WIDGET_DATA_CHANGED_ACTION.equals(intent.getAction())
|| CLOCK_TICK_ACTION.equals(intent.getAction())) {
PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
if (pm.isScreenOn()) {
onClockTick(context);
}
}
}
时钟小部件提供程序正在扩展 AppWidgetProvider。
世界时钟活动
private static void sendWidgetRefresh(Context context) {
// send update broadcast to widget
Intent broadcast = new Intent(ClockWidgetProvider.WIDGET_DATA_CHANGED_ACTION);
context.sendBroadcast(broadcast);
}
project link以供参考。遵循了以前的帖子,但没有成功。
