以下是我的代码：

    public class RetentionApplicationAddedBroadcastReceiver extends WakefulBroadcastReceiver {
    @Override
public void onReceive(Context context, Intent intent) {

    ComponentName comp = new ComponentName(context.getPackageName(),
            RetentionAddIntentService.class.getName());
    // Start the service, keeping the device awake while it is launching.
    startWakefulService(context, (intent.setComponent(comp)));
    setResultCode(Activity.RESULT_OK); //**LINE 18**
}

Answer 1

删除setResultCode()。这仅适用于有序广播，如the documentation for setResultCode()中所述。

Answer 2

修复它的干净方法如下：

if (isOrderedBroadcast()) {
    setResultCode(Activity.RESULT_OK);
}

BroadcastReceiver尝试在非有序广播期间返回结果 - 在Android中使用PACKAGE_ADDED
