React-native-branch-deep-linking-attribution: Session initialization already happened

[export-mike]

I have this issue trending on Sentry for my project.

Warning. Session initialization already happened. To force a new session, set intent extra, "branch_force_new_session", to true.

Example details, its affected around 87 users, 102 events.

Are you calling reInitSession anywhere, e.g. in MainActivity.onResume? If so, you can remove that.

[sandeepsingh91]

I'm facing the same error, below is the code for MainActivity.java

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

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

React Native Package :: "react-native-branch": "^4.4.0",

Are you calling reInitSession anywhere, e.g. in MainActivity.onResume? If so, you can remove that.

Getting the same issue, the only two things we have are this (from https://help.branch.io/developers-hub/docs/react-native)

// MainApplication.java
// add onCreate() override
@Override
public void onCreate() {
  super.onCreate();
  RNBranchModule.getAutoInstance(this);
}

and

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

@dozoisch I was facing the same issue here until I realised I was missing the android:launchMode="singleTask" property on AndroidManifest.xml Are you including it?

[jamesholcomb]

Same issue...in 4.4 (Android only) with singleTask.

[dozoisch]

@jpgarcia thanks for reply

yep I do have android:launchMode="singleTask" on the activity so not sure what's up

[StarryFire]

Wow, i finally managed to integrate this library within my project and now this is happening. :/

[alexsoul95]

any solution to this? having the same issue. android:launchMode="singleTask" and no reInitSession in MainApplication

[SteveTro]

I have the same problem if i take a picture with react-native-image-crop-picker.
As soon as i select a image i get the error Session initialization already happened. To force a new session, set intent extra, "branch_force_new_session", to true.

I also have singleTask and no reInitSession

[CoryWritesCode]

Still dealing with this. Have singleTask and no reInitSession on react-native-branch v5

[Svarto]

same problem with expo-branch, singleTask is specified and reInitSession is not called by myself nor the expo-branch. This is breaking deep links for me, as the app crashes and restarts which results in the deep link being lost.

[Seamus1989]

+1

[fi-nik]

I noticed that reInitSession is called inside RNBranchModule.onNewIntent(intent). on newIntent

[Svarto]

Any update on this issue? Did anyone get it to work?

@SteveTro
Were you able to find a solution?

I found using react-native-image-crop-picker doesn't trigger onNewIntent() but does trigger onStart() twice.

Android lifecycle https://developer.android.com/guide/components/activities/activity-lifecycle

I found the code below prevented the error but I don't know if it is bad to force a new session onResume().

In MainActivity.java

      @Override
      protected void onResume() {
          super.onResume();
          Intent intent = getIntent();
          setIntent(intent);
          intent.putExtra("branch_force_new_session", true);
      }

If you do not need cropping react-native-image-picker doesn't trigger a new branch session

Edit forcing a new session also works onRestart().
But i don't think there is much difference only is onRestart is not called from when the app is closed.

Opening a deeplink from the background.
onRestart -> onStart -> onResume -> onNewIntent

Opening a deeplink from closed
onCreate -> onStart -> onResume

      @Override
      protected void onRestart() {
          Log.v("Test", "restart");
          super.onRestart();
          Intent intent = getIntent();
          setIntent(intent);
          intent.putExtras(this.getIntent());
          intent.putExtra("branch_force_new_session", true);
      }

[flochtililoch]

@jdee any solution to solve this issue? In our app, we never call reInitSession and are also experiencing this issue - this prevents deep links from working when the app is running in the background

[tylerweitzman]

+1 on this issue, also happens every time we reload the app while debugging. Should we be forcing a new session or not?

[AndrewMorsillo]

This is still happening on Android. I integrated the SDK exactly per the docs. Can anybody from branch weigh in here since this has been open over a year now?
