MediaStyle：RemoteServiceException：从包发布的错误通知

Question

这是我的代码：

void startNotify(Context context, String playbackStatus, String title) {
    String titlesonge;
    String artist;
    try {
        titlesonge = StringUtils.substringBefore(title, " - ");
        artist = StringUtils.substringAfter(title, " - ");
    } catch (Exception e) {
        titlesonge = title.substring(0, title.indexOf(" - "));
        artist = title.substring(title.lastIndexOf(" - ") - 1);
    }
    int icon = R.drawable.ic_pause_white;
    Intent playbackAction = new Intent(service, RadioService.class);
    playbackAction.setAction(RadioService.ACTION_PAUSE);
    PendingIntent action = PendingIntent.getService(service, 1, playbackAction, 0);
    if (playbackStatus.equals(PlaybackStatus.PAUSED)) {
        icon = R.drawable.ic_play_white;
        playbackAction.setAction(RadioService.ACTION_PLAY);
        action = PendingIntent.getService(service, 2, playbackAction, 0);

    }
    Intent stopIntent = new Intent(service, RadioService.class);
    stopIntent.setAction(RadioService.ACTION_STOP);
    PendingIntent stopAction = PendingIntent.getService(service, 3, stopIntent, 0);

    Intent intent = new Intent(service, MainActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
            Intent.FLAG_ACTIVITY_SINGLE_TOP |
            Intent.FLAG_ACTIVITY_NEW_TASK);
    PendingIntent pendingIntent = PendingIntent.getActivity(service, 0, intent, 0);
    notificationManager.cancel(NOTIFICATION_ID);
    String PRIMARY_CHANNEL = "PRIMARY_CHANNEL_ID";
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        NotificationManager manager = (NotificationManager) service.getSystemService(Context.NOTIFICATION_SERVICE);
        String PRIMARY_CHANNEL_NAME = "PRIMARY";
        NotificationChannel channel = new NotificationChannel(PRIMARY_CHANNEL, PRIMARY_CHANNEL_NAME, NotificationManager.IMPORTANCE_LOW);
        channel.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);
        if (manager != null) {
            manager.createNotificationChannel(channel);
        }
    }
    NotificationCompat.Builder builder = new NotificationCompat.Builder(service, PRIMARY_CHANNEL)
            .setAutoCancel(false)
            .setContentTitle(titlesonge)
            .setContentText(artist)
            .setLargeIcon(BitmapFactory.decodeResource(resources, R.drawable.largeicon))
            .setContentIntent(pendingIntent)
            .setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
            .setSmallIcon(R.drawable.smallwidth)
            .setColor(ContextCompat.getColor(context, R.color.colorneeded))
            .addAction(icon, "pause", action)
            .addAction(R.drawable.ic_stop_white, "stop", stopAction)
            .setPriority(NotificationCompat.PRIORITY_HIGH)
            .setWhen(System.currentTimeMillis())
            .setStyle(new android.support.v4.media.app.NotificationCompat.MediaStyle()
                    .setMediaSession(service.getMediaSession().getSessionToken())
                    .setShowActionsInCompactView(0, 1)
                    .setShowCancelButton(true)
                    .setCancelButtonIntent(stopAction));
    service.startForeground(NOTIFICATION_ID, builder.build());
}

有谁能帮我解决这个问题吗

Answer 1

由于某种原因，使用.setstyle()方法时，带有Android 5.0的华为设备会崩溃，因此您有两种可能：

1-检测设备制造商是否为华为，是否具有Android5.0或以下版本

public boolean isLolliPopHuawei() {
    return (android.os.Build.VERSION.SDK_INT == Build.VERSION_CODES.LOLLIPOP_MR1 ||
            android.os.Build.VERSION.SDK_INT == Build.VERSION_CODES.LOLLIPOP) && Build.MANUFACTURER.equalsIgnoreCase("HUAWEI");
}

2-改用PlayerNotificationManager

void exoPlayerNotification(Context context, SimpleExoPlayer exoPlayer, String title) {
    String titlesonge;
    String artist;
    try {
        titlesonge = StringUtils.substringBefore(title, " - ");
        artist = StringUtils.substringAfter(title, " - ");
    } catch (Exception e) {
        titlesonge = title.substring(0, title.indexOf(" - "));
        artist = title.substring(title.lastIndexOf(" - ") - 1);
    }
    String finalArtist = artist;
    String finalTitlesonge = titlesonge;
    mPlayerNotificationManager = PlayerNotificationManager.createWithNotificationChannel(
            context,
            "PRIMARY_CHANNEL_ID",
            R.string.plaza,
            NOTIFICATION_ID,
            new PlayerNotificationManager.MediaDescriptionAdapter() {
                @Override
                public String getCurrentContentTitle(Player player) {
                    return finalArtist;
                }

                @Nullable
                @Override
                public PendingIntent createCurrentContentIntent(Player player) {
                    Intent intent = new Intent(service, MainActivity.class);
                    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                    return PendingIntent.getActivity(service, 0, intent,
                            PendingIntent.FLAG_UPDATE_CURRENT);
                }

                @Override
                public String getCurrentContentText(Player player) {
                    return finalTitlesonge;
                }

                @Nullable
                @Override
                public Bitmap getCurrentLargeIcon(Player player, PlayerNotificationManager.BitmapCallback callback) {
                    return BitmapFactory.decodeResource(service.getResources(), R.drawable.largeicon);
                }

                @Nullable
                @Override
                public String getCurrentSubText(Player player) {
                    return null;
                }
            }
    );
    mPlayerNotificationManager.setUseNavigationActions(false);
    mPlayerNotificationManager.setFastForwardIncrementMs(0);
    mPlayerNotificationManager.setRewindIncrementMs(0);
    mPlayerNotificationManager.setColorized(true);
    mPlayerNotificationManager.setColor(0xFFEEEEEE);
    mPlayerNotificationManager.setUseChronometer(true);
    mPlayerNotificationManager.setOngoing(true);
    mPlayerNotificationManager.setPriority(NotificationCompat.PRIORITY_MAX);
    mPlayerNotificationManager.setUsePlayPauseActions(true);
    mPlayerNotificationManager.setSmallIcon(R.drawable.smallwidth);
    mPlayerNotificationManager.setNotificationListener(new PlayerNotificationManager.NotificationListener() {
        @Override
        public void onNotificationStarted(int notificationId, Notification notification) {
            service.startForeground(notificationId, notification);
        }

        @Override
        public void onNotificationCancelled(int notificationId) {
            service.stopSelf();
            cancelNotify();
        }
    });
    mPlayerNotificationManager.setPlayer(exoPlayer);
}
