Android 10 screen sharing crash[bug]

[hrxiang]

Crash when screen sharing is turned on for the first time. Restart the app as normal

第一次使用屏幕分享功能会闪退，重启app后不在闪退。 Android 10 . Flutter 3.3.3 compileSdkVersion 33 targetSdkVersion 30

java.lang.SecurityException:Media projections require a foreground service of type ServiceInfo.FOREGROUND_SERVICE_TYPE_MEDIA_PROJECTION
android.os.Parcel.createException(Parcel.java:2091)

It should be related to the first setting of FOREGROUND_SERVICE, can this issue be reproduced in client-sdk-flutter/example?

I did some investigation, maybe it's a bug of flutter_background, after the first execution of FlutterBackground.initialize( androidConfig: androidConfig); will throw an exception, when you wait for 1 second and then re-execute FlutterBackground.enableBackgroundExecution(); it will succeed. so I created an experimental fix

You can wait 1 second after the first exception and try again, and screen sharing will work as expected.
