Linking.getInitialURL() for android

[sajaddp]

Hi,
On Android Linking.getInitialURL() has a problem and not return anything.
More precisely, none of the following logs are executed.

  Linking.getInitialURL().then((url) => {
      console.log('Initial url is: ' + url);
  }).catch(err => console.error('An error occurred', err));

but when i change https://github.com/facebook/react-native/blob/master/Libraries/Linking/Linking.js#L86-L92
to:

  getInitialURL(): Promise<?string> {
    return NativeLinking.getInitialURL();
  }

the problem was fixed.

I can confirm that on Android, if the app is closed, InteractionManager.runAfterInteractions, will not work and then the getInitialURL will not return anything.

But if the app was opened, everything works just fine.

I removed the InteractionManager.runAfterInteractions and the deep linking on Android, when the app is closed, works again

Thanks @sajaddp

I fixed by that:

var NativeLinking=require("./node_modules/react-native/Libraries/Linking/NativeLinking").default;
NativeLinking.getInitialURL().then((url) => {
      console.log('Initial url is: ' + url);
  }).catch(err => console.error('An error occurred', err));

I'm also facing this issue on RN v0.59.8. I'm trying to use aws-amplify library and they make use of Linking.getInitialUrl() to listen to the Deeplink URL but it is always returning null. Can anyone suggest some solutions that I can try?

Same here iOS is working great but Android fails.

System:
    OS: macOS 10.15.2
    CPU: (8) x64 Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz
    Memory: 68.70 MB / 16.00 GB
Packages:
    react: 16.9.0 => 16.9.0
    react-native: 0.61.2 => 0.61.2
    react-native-cli: 2.0.1

We are seeing what we think is the same issue—works great on iOS, fails on Android cold starts. In particular, it fails on Android 10. It works on an old Android 7 phone I have.

Any update on this? Or workaround?

Interestingly, getInitialUrl works on Google Pixel XL2 but doesn't work on Samsung S9 - both running Android 10.

I even changed code to:
import NativeLinking from "react-native/Libraries/Linking/NativeLinking";
NativeLinking.getInitialURL().then(handleDeepLinking);
(^^ code is cut down, I actually went as far as to put url into state and display in a <Text> for debug build, but nothing)

But to no avail... Samsung S9 refuses to call the handleDeepLinking function from cold start :( Warm start is fine, and anyway warm start is handled by Linking.addEventListener("url", ev => {
