Android only issue with initialising when no network

[bijuC1983]

I use Netinfo to monitor network connectivity and subscribe/unsubscribe to branch when the network connects/disconnects. The code snippet is here:

async componentDidMount() {
    const netState = await NetInfo.fetch();
    if(netState.isConnected === true){
      this.subscribeBranch();
    }
    this.unsubscribeNetInfo = NetInfo.addEventListener(state => {
      if (state.isConnected === false) {
        if (this.unsubscribeBranch !== null) {
          this.unsubscribeBranch();
        }
      } else if (
        state.isConnected === true 
      ) {
        setTimeout(()=>{
          this.subscribeBranch();
        },6000)
      }
    });
 }
subscribeBranch() {
    this.unsubscribeBranch = branch.subscribe(async ({error, params, uri}) => {
      if (error) {
        console.error('Error from Branch: ' + error);
        return;
      }

      // params will never be null if error is null

      if (params['+non_branch_link']) {
        const nonBranchUrl = params['+non_branch_link'];
        // Route non-Branch URL if appropriate.
        return;
      }

      if (!params['+clicked_branch_link']) {
        // Indicates initialization success and some other conditions.
        // No link was opened.
        return;
      }

      // A Branch link was opened.
      // Route link based on data in params, e.g.
    
    });
  }

In Android,

1. The app is killed
2. I disable all network and start the app
3. Since there is no data network and Wifi, branch subscribe is not called and ’No Internet Connection’ screen is displayed
4. Now if I enable the Wifi, branch subscribe in the NetInfo callback is called and we get the error seen in screenshot_1 attached with this mail. As you may see from the gist, I also delayed the subscribe call with a timer but to no avail.
5. The code in MainActivity.java is here :

@Override
    protected void onCreate(Bundle savedInstanceState) {
        // Use SplashTheme in AndroidManifest.xml for MainActivity, themes loads before layouts inflate
        setTheme(R.style.AppTheme); // Now set the theme from Splash to App before setContentView
        setContentView(R.layout.launch_screen); // Then inflate the new view
        SplashScreen.show(this, true);
        super.onCreate(savedInstanceState);
         if (!isTaskRoot()) {
            finish();
            return;
          }
    }

      // Override onStart, onNewIntent:
      @Override
      protected void onStart() {
          super.onStart();
          RNBranchModule.initSession(getIntent().getData(), this);
      }

      @Override
      public void onNewIntent(Intent intent) {
          super.onNewIntent(intent);
          setIntent(intent);
       }

This happens only for Android and iOS is working fine. I am on React Native: 0.61.5 and react-native-branch: 4.4.0

Did you ever find a workaround for this?

After some more testing it looks like the SDK becomes completely unresponsive if there is any error until the next time the app is foregrounded https://github.com/BranchMetrics/react-native-branch-deep-linking-attribution/issues/659

The unsubscribe function also doesn't work. It leaks a reference to your previous callback so two callbacks will be called next time you foreground the app.
