Android打ze模式会终止前卫媒体播放器服务

如何解决Android打ze模式会终止前卫媒体播放器服务

我一直在研究如何在后台（在线广播）中保持连续运行的音频播放活跃。最后，我为其提供了前台服务，并且可以在大多数手机上使用，但不能在Samsung Android P及更高版本上使用...（如“前台服务限制”一节中所示：https://proandroiddev.com/android-foreground-service-restrictions-d3baa93b2f70） 我听说有一个名为ExoPlayer的高级音频播放工具。这个lib可以帮我吗？

我已经尝试过以下解决方案：

每2秒
• ping google.com
• 请求电池优化忽略
• 使用以下方法为mediplayer设置唤醒锁：setWakeMode（context，PowerManager.PARTIAL_WAKE_LOCK）（仍在使用）

启动服务：

viewModel.isMusicControlServiceNeedToStart.observe(this,Observer {
        if (it) {
            val intent = Intent(this,MusicControlForegroundServiceImpl::class.java).apply { action = ACTION_SHOW_MUSIC_CONTROL }
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) startForegroundService(intent) else startService(intent)
        } else {
            stopService(Intent(this,MusicControlForegroundServiceImpl::class.java))
        }
    })

服务本身：

class MusicControlForegroundServiceImpl : Service(),KoinComponent {

private val notificationManager: NotificationManager by inject()
private val radioManager: RadioManager by inject()
private val context: Context by inject()
private val preferences: Preferences by inject()

override fun onStartCommand(intent: Intent?,flags: Int,startId: Int): Int {
    if (intent != null && intent.action == ACTION_SHOW_MUSIC_CONTROL) {
        val lastSelectedRadio = preferences.getJSON(Globals.LAST_SELECTED_RADIO_KEY,Radio::class.java)
                ?: return START_NOT_STICKY
        val notification = notificationManager.createMediaControlNotificationIfNeeded(context,lastSelectedRadio)
        startForeground(1,notification)
    }
    return START_NOT_STICKY
}

override fun onTaskRemoved(rootIntent: Intent?) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) startForegroundService(rootIntent) else startService(rootIntent)
    super.onTaskRemoved(rootIntent)
}

override fun onDestroy() {
    if (!notificationManager.musicControlServiceRestart) radioManager.release()
    synchronized(MUSIC_CONTROL_SERVICE_LOCK) { notificationManager.musicControlServiceRestart = false }
    synchronized(MEDIA_PLAYER_LOCK) { radioManager.lastPlayedMediaUrl = null }
    stopForeground(true)
    super.onDestroy()
}

override fun onBind(intent: Intent?): IBinder? = null

}

通知创建：

 override fun createMediaControlNotificationIfNeeded(context: Context,selectedRadio: Radio): Notification {
    val resultIntent = Intent(context,RadioDetailActivity::class.java)
    val resultPendingIntent: PendingIntent? = TaskStackBuilder.create(context).run {
        addNextIntentWithParentStack(resultIntent)
        getPendingIntent(0,PendingIntent.FLAG_UPDATE_CURRENT)
    }
    val playIntent = Intent(context,NotificationReceiver::class.java).apply {
        putExtra(MusicState::class.java.name,MusicState.PLAY)
    }
    val pauseIntent = Intent(context,MusicState.PAUSE)
    }

    val notificationManager = NotificationManagerCompat.from(context)

    @Suppress("DEPRECATION") val builder = NotificationCompat.Builder(context,CHANNEL_ID)
            .setSmallIcon(R.drawable.ic_notification_icon)
            .setContentTitle(selectedRadio.name)
            .setDefaults(0)
            .setOngoing(true)
            .setNotificationSilent()
            .addAction(
                    R.drawable.ic_notification_pause,context.getString(R.string.pause),PendingIntent.getBroadcast(context,1,pauseIntent,0)
            )
            .addAction(
                    R.drawable.ic_notification_play,context.getString(R.string.play),2,playIntent,0)
            )
            .setStyle(
                    androidx.media.app.NotificationCompat.MediaStyle().setMediaSession(
                            MediaSessionCompat(
                                    context,RadioDetailActivity::class.java.name
                            ).sessionToken
                    )
            )
            .setContentIntent(resultPendingIntent)

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        val channel = NotificationChannel(
                CHANNEL_ID,context.getString(R.string.app_name),NotificationManager.IMPORTANCE_LOW
        )
        notificationManager.createNotificationChannel(channel)
        builder.setChannelId(CHANNEL_ID)
    }

    return builder.build()
}

如果您需要任何其他资源，请让我知道并提供帮助！我已经为这个问题苦苦挣扎了好几个星期了..：（

更新 现在，我每隔2分钟会发出媒体控制通知以更新以前的内容，因此该应用程序在受影响的手机上可以像30分钟一样存活，但仍然无法正常工作...
