我有一个叫BroadcastReceiver
的服务。它工作正常,但在我更改后端系统以处理通知ID后,最终通知更新应更新通知以告知用户进程已完成。但是,除非我在处理这些通知的方法中在调试模式中放置断点,否则最终更新将无法通过。如果未放置断点或调试模式未激活,则不会发生最终通知更新,并且通知将显示其最后状态,该状态告知用户该进程尚未完成,但情况并非如此。
这是方法,Log.d()
s显示正确调用manager.notify()
方法来更新通知以表示该过程已完成。
@Override
public void onReceive(Context context, Intent intent) {
Download data = null;
try {
data = (Download) intent.getSerializableExtra(Commons.ARGS.DATA);
} catch (ClassCastException | NullPointerException e) {
e.printStackTrace();
}
switch (intent.getIntExtra(Commons.ARGS.RESULT, Commons.ARGS.FAILED)) {
case Commons.ARGS.DESTROY:
Log.w(TAG, "Service was destroyed");
if (notifications && manager != null) {
Download[] remaining = (Download[]) intent.getParcelableArrayExtra(Commons.ARGS.DATA);
if (remaining == null) break;
for (Download d : remaining) {
// Download has failed since service was destroyed; was never called and has no relations to this case. manager.notify() is called here to update the notification as "cancelled" btw
}
}
break;
case Commons.ARGS.ERR_LOAD:
Log.w(TAG, "Failed to load queue");
break;
}
if (data == null) return;
if (notifications) {
Intent i = new Intent(context, MainActivity.class);
NotificationCompat.Builder builder = new NotificationCompat.Builder(activity, Commons.Notif.DOWNLOAD_PROGRESS)
.setContentIntent(PendingIntent.getActivity(activity, 0, i, 0))
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setSmallIcon(R.drawable.ic_notif)
.setContentTitle(data.title)
.setColor(context.getResources().getColor(R.color.Accent))
.setGroupAlertBehavior(NotificationCompat.GROUP_ALERT_SUMMARY)
.setGroup(CHANNEL_ID);
if (manager == null) {
manager = (NotificationManager) activity.getSystemService(Context.NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel(CHANNEL_ID, "Downloads in Progress", NotificationManager.IMPORTANCE_DEFAULT);
channel.setDescription("All downloads are displayed here");
channel.enableLights(false);
channel.enableVibration(false);
manager.createNotificationChannel(channel);
}
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
builder.setChannelId(CHANNEL_ID);
}
// Notification builder styling is handled here
manager.notify(0, new NotificationCompat.Builder(activity, Commons.Notif.DOWNLOAD_PROGRESS)
.setChannelId(CHANNEL_ID)
.setSmallIcon(R.drawable.ic_notif)
.setGroup(CHANNEL_ID)
.setColor(activity.getResources().getColor(R.color.Accent))
.setGroupAlertBehavior(NotificationCompat.GROUP_ALERT_SUMMARY)
.setGroupSummary(true)
.setContentText("All downloads have finished.")
.setContentTitle("Done")
.build());
manager.notify(DOWNLOAD_BASE_ID | (data.id & 0x00FF_FFFF), builder.build());
Log.d(TAG, "Notification updated");
}
}
在此先感谢:P
我不知道究竟发生了什么,但在使用manager.cancel()
取消通知之前,使用成功/最终通知更新了问题。
int id = // Notification id
if (success) {
Log.d(TAG, "Success Notification updated");
manager.cancel(id);
} else Log.d(TAG, "Notification updated");
manager.notify(id, builder.build());
