java–Android Oreo Notification崩溃系统UI

概述我已经设法在较旧的API中使用通知,但不是Oreo.创建通知会导致我的应用程序仍能正常工作(logcat中没有消息),但是当Activity运行时,SystemUI会在无限循环中崩溃并重新启动.这是systemui进程的logcat错误：java.lang.IllegalArgumentException:widthandheightmustbe>0我的代

我已经设法在较旧的API中使用通知,但不是Oreo.创建通知会导致我的应用程序仍能正常工作(logcat中没有消息),但是当Activity运行时,systemUI会在无限循环中崩溃并重新启动.这是systemUI进程的logcat错误：

java.lang.IllegalArgumentException: wIDth and height must be > 0

我的代码：

private voID showPlayingNotification() {        NotificationCompat.Builder builder = mNotificationUtils.getAndroIDChannelNotification(this, "Play", mMediaSessionCompat);        if( builder == null ) {            Log.i("Play Notification","No notification found!");            return;        }        mNotificationUtils.getManager().notify(101,builder.build()); }

我在我创建的MediaPlayerService的onCreate中初始化了mNotificationUtils.

public class NotificationUtils extends Contextwrapper {    private notificationmanager mManager;    public static final String AUdio_CHANNEL_ID = "com.liftyourheads.dailyreadings.dailyReadingsAudio";    public static final String AUdio_CHANNEL_name = "Daily Readings Audio Stream";    public NotificationUtils(Context base) {        super(base);        createChannels();    }    public voID createChannels() {        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {            // create androID channel            NotificationChannel dailyReadingsAudioChannel = new NotificationChannel(AUdio_CHANNEL_ID,                    AUdio_CHANNEL_name, notificationmanager.importANCE_HIGH);            getManager().createNotificationChannel(dailyReadingsAudioChannel);        }    }    public notificationmanager getManager() {        if (mManager == null) {            mManager = (notificationmanager) getSystemService(Context.NOTIFICATION_SERVICE);        }        return mManager;    }    public NotificationCompat.Builder getAndroIDChannelNotification(Context context, String action, MediaSessionCompat mediaSession) {        if (action.equals("Play")) {            return MediaStyleHelper.from(context, mediaSession)                    .addAction(new NotificationCompat.Action(androID.R.drawable.ic_media_pause, "Pause", MediabuttonReceiver.buildMediabuttonPendingIntent(this, PlaybackStateCompat.ACTION_PLAY_PAUSE)))                    .setStyle(                            new androID.support.v4.media.app.NotificationCompat.MediaStyle()                                    .setShowActionsInCompactVIEw(0)                                    .setMediaSession(mediaSession.getSessionToken()))                    .setSmallicon(R.mipmap.ic_launcher)                    .setContentText("Content Text")                    .setContentTitle("Content Title")                    .setChannelID(AUdio_CHANNEL_ID);        } else if (action.equals("Pause")) {            return MediaStyleHelper.from(context, mediaSession)                    .addAction(new NotificationCompat.Action(androID.R.drawable.ic_media_play, "Play", MediabuttonReceiver.buildMediabuttonPendingIntent(this, PlaybackStateCompat.ACTION_PLAY_PAUSE)))                    .setStyle(                            new androID.support.v4.media.app.NotificationCompat.MediaStyle()                                    .setShowActionsInCompactVIEw(0)                                    .setMediaSession(mediaSession.getSessionToken()))                    .setSmallicon(R.mipmap.ic_launcher)                    .setContentText("Content Text")                    .setContentTitle("Content Title")                    .setChannelID(AUdio_CHANNEL_ID);        }        return null;    } }

解决方法:

从mipmap切换到drawable图标.有关更多信息,请参见this issue
