Error reason:

If an application for Android 8.0 tries to use the startservice() function without allowing it to create a background service, the function will raise a IllegalStateException

The new context. Startforeroundservice() function will start a foreground service. Now, even if the application runs in the background, the system allows it to call context. Startforeroundservice() . However, the application must call the startforegroup() function of the service within five seconds after the service is created

For more information, see background execution restrictions

Solution:

In the place where the service was originally started, set startservice(); Replace with the following code

Intent intent = new Intent(context, MyService.class);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    context.startForegroundService(intent);
} else {
   context.startService(intent);
}

And add it in the class of service (this content can be ignored if it runs normally after adding the above code)

@Override
public void onCreate() {
    super.onCreate();
   if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
       startForeground(1,new Notification()); 
}
