The current version of the aurora push SDK does not support the startup service in the current mobile phone system. This is the problem that the old Aurora push SDK does not adapt to Android 8.0 mobile phones. At present, the new version of the aurora SDK does not have that problem, so the solution is to replace it with the latest Aurora SDK

Go to the official website to download the latest version of Aurora push SDK. Download address:
https://docs.jiguang.cn/jpush/resources/

Copy everything in the downloaded lib to the corresponding lib file of your project and rely on it,

Copy the file in res to the corresponding project res file (please check that the file in res of your project does not have the same name as it, otherwise it will be replaced, resulting in the loss of your project resource file)

Then configure the following code in Android manifest:

as
public class ExampleApplication extends Application {br/>@Override
public void onCreate() {
super.onCreate();
JPushInterface.setDebugMode(true);
JPushInterface.init(this);
}
}
