android oreo ui,java - Android Oreo Notification Crashes System UI

本文探讨了在Android Oreo系统中，应用创建通知导致System UI崩溃并重启的问题。作者分享了代码片段，重点在于NotificationCompat.Builder的使用和针对Oreo及以上版本创建通知渠道的方法。解决方案可能涉及检查宽高参数和正确配置Notification Channel。

I've managed to get notifications working in older API's, but not Oreo. Creating the notification causes my app to still work fine (no messages in logcat), however SystemUI crashes and reboots in an endless cycle while the Activity is running. The is the error in logcat for the systemui process:

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

My code:

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());

}

I initialised mNotificationUtils in the onCreate of the MediaPlayerService I created.

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")) {
