我正在尝试使用以下代码在我的应用中创建一个通知媒体控制器，该代码在所有使用 Android 5.0 的设备上都可以正常工作， Huawei P8 Lite 从Firebase测试实验室获取此错误日志：

service.startForeground(NOTIFICATION_ID, builder.build());
}
任何人都可以帮助我解决此问题

由于某些华为设备不支持MediaStyle，因此您需要在不设置样式的情况下构建通知。我在此机型Huawei P8 Lite和Huawei Y3II上遇到了这个问题。因此，请检查设备是否为华为和提及的SDK版本，并创建如下的简单通知。这个问题帮助我找到了解决方法Strange allow/deny question on Huawei 5.1 phone when showing notification 。无论如何，希望对某人有帮助
boolean isLollipopHuawei = (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");
if (isLollipopHuawei) {
builder
.setContentTitle(description.getTitle())
.setContentText(contentText)
.setOngoing(true)
.setContentIntent(createContentIntent())
.setLargeIcon(BitmapFactory.decodeResource(context.getResources(),
R.drawable.mobi_plc))
.addAction(R.drawable.ic_previous_outline_notification,
this.service.getString(R.string.next_station),
MediaButtonReceiver.buildMediaButtonPendingIntent(
this.service,
PlaybackStateCompat.ACTION_SKIP_TO_PREVIOUS))
.addAction(R.drawable.ic_next_outline_notification,
this.service.getString(R.string.next_station),
MediaButtonReceiver.buildMediaButtonPendingIntent(
this.service,
PlaybackStateCompat.ACTION_SKIP_TO_NEXT))
.setSmallIcon(R.drawable.ic_stat)
.setAutoCancel(false);
}

由于某些原因，使用.setStyle()方法时，装有Android 5.0的华为设备会崩溃，因此有两种可能：
1-检测设备制造商是否为华为，以及是否具有Android 5.0或更低版本
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);
}

我遇到了同样的问题，根本原因是无法设置setStyle，它只是在Huawei P8 Lite中给出了此异常，而在其他设备上则没有。
所以，我要做的是检查当前设备是否为android 5.0版本，其制造商为Huawei并删除setStyle属性。请检查以下代码
boolean isLollipopHuawei = (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");
if (Build.VERSION.SDK_INT == Build.VERSION_CODES.KITKAT || Build.VERSION.SDK_INT == Build.VERSION_CODES.LOLLIPOP_MR1 || Build.VERSION.SDK_INT == Build.VERSION_CODES.LOLLIPOP) {
if (isLollipopHuawei) {
return builder
.addAction(generateAction(android.R.drawable.ic_media_previous, "Previous", Constants.ACTION_PREVIOUS))
.addAction(action)
.addAction(generateAction(android.R.drawable.ic_media_next, "Next", Constants.ACTION_NEXT))
.setSmallIcon(R.mipmap.vpicon_grayscale)
.setContentTitle(getSongDataHelper().getTitle())
.setContentIntent(pendingIntent)
.setContentText(getSongDataHelper().getAlbum())
.setLargeIcon(getSongDataHelper().getAlbumArt())
//.setColor(color)
/* .setStyle(new androidx.media.app.NotificationCompat.MediaStyle()
.setShowActionsInCompactView(0, 1, 2)
.setMediaSession(mMediaSession.getSessionToken()))*/
.build();
} else {
return builder
.addAction(generateAction(android.R.drawable.ic_media_previous, "Previous", Constants.ACTION_PREVIOUS))
.addAction(action)
.addAction(generateAction(android.R.drawable.ic_media_next, "Next", Constants.ACTION_NEXT))
.setSmallIcon(R.mipmap.vpicon_grayscale)
.setContentTitle(getSongDataHelper().getTitle())
.setContentIntent(pendingIntent)
.setContentText(getSongDataHelper().getAlbum())
.setLargeIcon(getSongDataHelper().getAlbumArt())
//.setColor(color)
.setStyle(new androidx.media.app.NotificationCompat.MediaStyle()
.setShowActionsInCompactView(0, 1, 2)
.setMediaSession(mMediaSession.getSessionToken()))
.build();
}
}
