Android only - PlatformException(-120, Trouble initializing Branch. Task exceeded timeout., null, null)

[gabidev89]

Description
When app starts, there's a throw that occurs. after that the app deeplink data is clear , FlutterBranchSdk.getLatestReferringParams() fails to retrieve the data, also FlutterBranchSdk.listSession().listen is never triggered.
Everything works on iOS. Happens only on android.

Steps to reproduce
Steps to reproduce the behavior:

1. Implement Flutter SDK for Android
2. Run debug on Android
3. Debug will pause due to SDK Throw
4. Continue debug
5. Try opening app from deeplink when app is in background
6. Deeplink data is empty

Expected behavior
Init should complete without throwing on android, listener should be called when app is opened by deeplink

Screenshots

Mobile:

• Flutter: version: 3.24.5
• flutter_branch_sdk version: 8.3.1
• OS: Android 15
• Device: Pixel 6A

[gabidev89]

Requested info was edited in, is there a fix on the way? any suggestions how can i workaround the issue? branch sdk completely crashes on android...

[RodrigoSMarques]

Are you running from an emulator?

Have you given internet permission in the AndroidManifest.xml for the app?

Have you checked if the device has internet access? Can it access pages via the browser?

This error message is returned by the Branch SDK, not the Flutter plugin.

Open a support ticket for Branch at the link or open an issue in the platform repository:

• Android: https://github.com/BranchMetrics/android-branch-deep-linking-attribution
• iOS: https://github.com/BranchMetrics/ios-branch-deep-linking-attribution

[gabidev89]

• Multiple real devices, samsung and pixel.
• Manifest has :
  <uses-permission android:name="android.permission.INTERNET" />
• App is running and working with server, no connectivity issues.

Is there any other required configuration for android support beside what is described in the readme that might be required.
Everything worked before...

[RodrigoSMarques]

Ad blockers interfere with the SDK's operation. I don't know if this is the case.

As I mentioned above. This is a message returned by the Native SDK.

I suggest you contact the Branch support team.

[gabidev89]

I've contacted the native team but no response...
I've updated to 8.3.2, there's a lot more logging...
