无法展开RemoteViews - 错误通知

Question

最近我收到越来越多的用户收到RemoteServiceException错误的报告.我每次给出的堆栈跟踪如下:

android.app.RemoteServiceException: Bad notification posted from package com.smithyproductions.fasttracks: Couldn't expand RemoteViews for: StatusBarNotification(pkg=com.smithyproductions.fasttracks id=311095 tag=null score=0 notn=Notification(pri=0 contentView=com.smithyproductions.fasttracks/0x7f03007d vibrate=null sound=null defaults=0x0 flags=0x62 kind=[null]) user=UserHandle{0})

我似乎永远无法在HTC Sensation或HTC One X上重现这个问题,这让我相信它可能是特定于设备的.我从以下设备收到了此错误的报告:

• 华为G610 U15
• bq Aquaris 5 HD
• 恩斯珀特楼梯
• JYT JY-G5

...而且他们都在运行Android 4.2.1 - 也许这个版本的Android存在错误？

我已经搜索过具有类似问题的人的互联网和StackOverflow,虽然有很多人在这个问题上有很多人因为不正确的资源ID或使用不受支持的视图RemoteViews.我不明白怎么可能会是我做错了,如果它适用于设备的98%,但我并不想告诉这些人的问题,有什么我可以做,要么.

就我创建通知的方式而言,我使用NotificationCompat.Builder类和自定义RemoteViews - 基本上它是一个音乐播放器通知,因此它上面也有一些ImageButtons.

这是我设置通知的代码:

PendingIntent pi = PendingIntent.getActivity(
                getApplicationContext(), 0, new Intent(getApplicationContext(), Showcase.class),
                PendingIntent.FLAG_UPDATE_CURRENT);

RemoteViews smallContentView = new RemoteViews(getPackageName(),
                R.layout.notif_layout);

nowPlayingNotification = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.notification_icon)
                .setContentTitle(
                        "Playing: "
                                + playbackManager.getCurrentTrack()
                                        .getName()).setContentIntent(pi)
                .setOngoing(true)
                .setWhen(System.currentTimeMillis())
                .setContent(smallContentView).build();

然后我设置RemoteViews按钮的所有回调:

Intent playIntent = new Intent(this, RemoteControlReceiver.class);
    playIntent.setAction(ACTION_TOGGLE_PLAYBACK);
    PendingIntent playPausePendingIntent = PendingIntent.getBroadcast(this,
            0, playIntent, 0);

    Intent nextIntent = new Intent(this, RemoteControlReceiver.class);
    nextIntent.setAction(ACTION_SKIP);
    PendingIntent nextPendingIntent = PendingIntent.getBroadcast(this, 0,
            nextIntent, 0);

    Intent stopIntent = new Intent(this, RemoteControlReceiver.class);
    stopIntent.setAction(ACTION_STOP);
    PendingIntent stopPendingIntent = PendingIntent.getBroadcast(this, 0,
            stopIntent, 0);

    nowPlayingNotification.contentView.setTextViewText(R.id.title,
            playbackManager.getCurrentTrack().getName());

    nowPlayingNotification.contentView.setProgressBar(
            android.R.id.progress, 100, mediaProgress, false);

    if (notificationIconMixBitmap != null)
        nowPlayingNotification.contentView.setImageViewBitmap(R.id.icon,
                notificationIconMixBitmap);
    else {
        nowPlayingNotification.contentView.setImageViewResource(R.id.icon,
                R.drawable.notification_icon);

    }

    nowPlayingNotification.contentView.setOnClickPendingIntent(
            R.id.playPause, playPausePendingIntent);

    if (playbackManager.getCurrentPlaybackState() == State.Paused) {
        nowPlayingNotification.contentView.setImageViewResource(
                R.id.playPause, R.drawable.play_icon_solid);
    } else {
        nowPlayingNotification.contentView.setImageViewResource(
                R.id.playPause, R.drawable.pause_icon_solid);
    }

    if (!playbackManager.isSkipAllowed()) {
        nowPlayingNotification.contentView.setImageViewResource(R.id.next,
                R.drawable.next_icon_disabled);
    } else {
        nowPlayingNotification.contentView.setImageViewResource(R.id.next,
                R.drawable.next_icon_solid);
    }

    if (playbackManager.getCurrentPlaybackState() == State.Preparing) {
        nowPlayingNotification.contentView.setProgressBar(
                android.R.id.progress, 100, mediaProgress, true);
    }

    nowPlayingNotification.contentView.setOnClickPendingIntent(R.id.next,
            nextPendingIntent);
    nowPlayingNotification.contentView.setOnClickPendingIntent(R.id.close,
            stopPendingIntent);

其次是

mNotificationManager.notify(NOTIFICATION_ID, nowPlayingNotification);

如果有人知道任何可以帮助的事情,也许是4.2.1中公认的错误,我将不胜感激!谢谢

我的手机也有同样的问题。

您使用以下代码创建通知：

nowPlayingNotification = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.notification_icon)
                .setContentTitle(
                        "Playing: "
                                + playbackManager.getCurrentTrack()
                                        .getName()).setContentIntent(pi)

如果您的挂起意图 -> 指定要启动的意图的 pi 设置为 null，则应用程序崩溃，如下所示：

  PendingIntent pi= PendingIntent.getActivity(
                getApplicationContext(),
                0,
                ***null***,
                0
            );

将 null 替换为 new Intent() 并测试是否解决了问题。

在 Gingerbread 上 .setcontentIntent(intent) 是强制性的，否则将抛出 IllegalArgumentException。但在 Jellybean 中，如果我们删除 .setcontentIntent(intent) ，则不会引发异常
