如何使用 React Native 检测 Android 手机中的电话？

Question

I'm building an app and I need to detect all phone calls, assuming my app is always in the background.

I've looked over react-native-call-detection package from https://www.npmjs.com/package/react-native-call-detection .

The question is, how do I make the listener global , meaning that it doesn't matter in which screen the user is or if the app is in background, how to detect incoming calls?

Answer 1

You could create a new class for the listener, than make a new class element in every screen. For example you create a class like, phoneCallListener, this class has a constructor, and a function which starts the detection, which name would be, startDetection(); Then in every activity you create a new element, like phoneCallListener myListener = new phoneCallListener(); , then you call the method and you are read, myListener.startDetection();

Another soluton is to make only one screen with fragments, so you will have one activity which's screen can change, so there will be a global class, and a fragment class.
