我有一个解决这个问题的办法。我已经在自己的应用(DAU超过30万)中验证了这一修复方法，它至少可以减少95%的这种崩溃，但仍然不能100%避免这个问题。

即使您确保在服务启动后调用start前台()，也会发生此问题。这可能是因为在很多情况下，服务创建和初始化过程已经花费了超过5秒的时间，那么无论何时何地调用startForeground()方法，这个崩溃都是不可避免的。

我的解决方案是确保start前台()将在startForegroundService()方法后的5秒内执行，无论您的服务需要创建和初始化多长时间。下面是详细的解决方案。

Do not use startForegroundService at the first place, use bindService() with auto_create flag. It will wait for the service initialization. Here is the code, my sample service is MusicService: final Context applicationContext = context.getApplicationContext(); Intent intent = new Intent(context, MusicService.class); applicationContext.bindService(intent, new ServiceConnection() { @Override public void onServiceConnected(ComponentName name, IBinder binder) { if (binder instanceof MusicBinder) { MusicBinder musicBinder = (MusicBinder) binder; MusicService service = musicBinder.getService(); if (service != null) { // start a command such as music play or pause. service.startCommand(command); // force the service to run in foreground here. // the service is already initialized when bind and auto_create. service.forceForeground(); } } applicationContext.unbindService(this); } @Override public void onServiceDisconnected(ComponentName name) { } }, Context.BIND_AUTO_CREATE); Then here is MusicBinder implementation: /** * Use weak reference to avoid binder service leak. */ public class MusicBinder extends Binder { private WeakReference<MusicService> weakService; /** * Inject service instance to weak reference. */ public void onBind(MusicService service) { this.weakService = new WeakReference<>(service); } public MusicService getService() { return weakService == null ? null : weakService.get(); } } The most important part, MusicService implementation, forceForeground() method will ensure that startForeground() method is called just after service start: public class MusicService extends MediaBrowserServiceCompat { ... private final MusicBinder musicBind = new MusicBinder(); ... @Override public IBinder onBind(Intent intent) { musicBind.onBind(this); return musicBind; } ... public void forceForeground() { // API lower than 26 do not need this work around. if (Build.VERSION.SDK_INT >= 26) { Notification notification = mNotificationHandler.createNotification(this); // call startForeground just after service start. startForeground(Constants.NOTIFICATION_ID, notification); } } } If you want to run the step 1 code snippet in a pending intent, such as if you want to start a foreground service in a widget (a click on widget button) without opening your app, you can wrap the code snippet in a broadcast receiver, and fire a broadcast event instead of start service command.

仅此而已。希望能有所帮助。祝你好运。

服务

class TestService : Service() {

    override fun onCreate() {
        super.onCreate()
        Log.d(TAG, "onCreate")

        val nBuilder = NotificationCompat.Builder(this, "all")
            .setSmallIcon(R.drawable.ic_launcher_foreground)
            .setContentTitle("TestService")
            .setPriority(NotificationCompat.PRIORITY_DEFAULT)
        startForeground(1337, nBuilder.build())
    }

    override fun onStartCommand(intent: Intent?, flags: Int, startId: Int): Int {
        val rtn = super.onStartCommand(intent, flags, startId)

        if (intent?.action == STOP_ACTION) {
            Log.d(TAG, "onStartCommand -> STOP")
            stopForeground(true)
            stopSelf()
        } else {
            Log.d(TAG, "onStartCommand -> START")
        }

        return rtn
    }

    override fun onDestroy() {
        Log.d(TAG, "onDestroy")
        super.onDestroy()
    }

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

    companion object {

        private val TAG = "TestService"
        private val STOP_ACTION = "ly.zen.test.TestService.ACTION_STOP"

        fun start(context: Context) {
            ContextCompat.startForegroundService(context, Intent(context, TestService::class.java))
        }

        fun stop(context: Context) {
            val intent = Intent(context, TestService::class.java)
            intent.action = STOP_ACTION
            ContextCompat.startForegroundService(context, intent)
        }

    }

}

测试人员

val nChannel = NotificationChannel("all", "All", NotificationManager.IMPORTANCE_NONE)
val nManager = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
nManager.createNotificationChannel(nChannel)

start_test_service.setOnClickListener {
    TestService.start(this@MainActivity)
    TestService.stop(this@MainActivity)
}

结果

D/TestService: onCreate
D/TestService: onStartCommand -> START
D/TestService: onStartCommand -> STOP
D/TestService: onDestroy

提醒一下，我在这上面浪费了太多时间。我一直得到这个异常，即使我调用start前台(..)作为onCreate(..)的第一件事。 最后，我发现这个问题是由于使用NOTIFICATION_ID = 0引起的。使用任何其他值似乎都可以解决这个问题。

我已经修复了用startService(intent)而不是context . start前台()启动服务的问题，并在super.OnCreate()之后立即调用start前台()。此外，如果您在引导时启动服务，您可以启动在引导广播时启动服务的Activity。虽然这不是一个永久的解决方案，但它是有效的。

此错误也发生在Android 8+服务时。start前台(int id, Notification Notification)在id设置为0时被调用。

id int:该通知的标识符，根据NotificationManager。通知(int、通知);一定不是0。

Android O API 26的问题

如果你立即停止服务(所以你的服务实际上并没有真正运行(措辞/理解)，并且你在ANR间隔之下，你仍然需要在stopSelf之前调用start前台

尝试了这种方法，但它仍然创建一个错误:-

if (Util.SDK_INT > 26) {
    mContext.startForegroundService(playIntent);
} else {
    mContext.startService(playIntent);
}

我正在使用这个，直到错误被解决

mContext.startService(playIntent);
