Android: Crash on cold start when opening a universal link

[flochtililoch]

Our app handles links for two formats:

• our own app scheme (i.e. "myapp://")
• universal link (via Branch), via https scheme, (i.e. "https://myapp.app.link")

When opening a regular app link ("myapp://"), the app opens normally. However when opening a Branch link, we're seeing this crash:

AndroidRuntime: FATAL EXCEPTION: main

Here's how our links are configured:

AndroidManifest.xml, under application/activity:

      <!-- Deeplinks using myapp:// scheme -->
      <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data android:scheme="myapp" android:host="*" />
      </intent-filter>

      <!-- Branch links -->
      <intent-filter android:autoVerify="true">
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data android:scheme="https" android:host="myapp.app.link" />
      </intent-filter>

and how are MainActivity..onStart / MainActivity.handleIntentInIterable handler look like

   ...

   @Override
    protected void onStart() {
        super.onStart();

        RNBranchModule.initSession(this.getIntent().getData(), this);
        handleIntentInIterable(getIntent());
    }

    ...


    private void handleIntentInIterable(Intent intent) {
        if (Intent.ACTION_VIEW.equals(intent.getAction()) && intent.getData() != null) {
            IterableApi.getInstance().handleAppLink(intent.getDataString());
        }
    }

We're temporarily wrapping the failing statement (IterableApi.getInstance().handleAppLink(intent.getDataString());) into a try/catch block, but this is likely causing issues on our tracking.

Can you advise on what the issue might be? TIA

Some additional information:

• We're implementing Iterable SDK via react-native (using Iterable's wrapper "@iterable/react-native-sdk": "1.3.17")
• The version of the Iterable SDK that this wrapper pulls in is com.iterable:iterableapi:3.4.16

Our Java version:

% java --version
openjdk 17.0.8.1 2023-08-24
OpenJDK Runtime Environment Homebrew (build 17.0.8.1+0)
OpenJDK 64-Bit Server VM Homebrew (build 17.0.8.1+0, mixed mode, sharing)

Additional params from our build.gradle:

buildscript {
     ext {
        buildToolsVersion = "30.0.2"
        minSdkVersion = 23
        compileSdkVersion = 33
        targetSdkVersion = 33
        ndkVersion = "21.4.7075529"
        kotlinVersion = "1.8.21"
    }
