Hi

I got an error message when i send a push message to my game in Android Oreo.
The game works well for all previous version of Android Oreo.
It only happens in Android Oreo.
I have searched many answers in this forum.
Some people say that i have to use FCM instead of GCM.
But I can't change my old Eclipse project to Android Studio because of many risks.
I use gcm.jar library.
Please help me & thanks in advance!

  • *I have searched many answers in this forum.* - you didn't search very well. I just copied your error and found the exact same question – Tim Dec 11 '17 at 12:41
  • many people tell me to refer to the manual of 'backround execution limits'. or they say that i have to use 'startForegroundService' instead of 'startService'. but i can't understand what to do. i just use '' in AndroidManifest.xml file. and i use 'public class GCMIntentService extends GCMBaseIntentService { ... }'. that's all. it works well for all version of android except android oreo. please give me an example code. – Ki Seok Kim Dec 11 '17 at 13:09
  • @KiSeokKim Have you got the example ? – mob_web_dev Dec 25 '17 at 10:55

Starting from Android O.

The startService() method now throws an IllegalStateException if an app targeting Android 8.0 tries to use that method in a situation when it isn't permitted to create background services.

By default, these restrictions only apply to apps that target O,but if user enable these restrictions for a particular app, then app will treated as same. For more info on topic read Background execution limits section here.

From API 26 onwords you won't be allow to start or destroy services in background.

https://developer.android.com/about/versions/oreo/background.html

for more detail read here.

There are so much limitations in API 26 for battery optimizations and some security reasons.
