I didn't understand: "When I open another app from my app and then click default back button to go back my app".

Can you give me an example of an application being opened so I can try to reproduce the error?

[uyit14]

This is flow:

1. At "My App" click on a phone_number to open Phone app (the code is: launch('tel:${"84357xxxxxx"}');) -> Phone app opened
2. Click OS back button -> app crash with above information.

I added below code to FlutterBranchSdkPlugin.java and crash is not happen now.
public void success(final Object o) { handler.post(new Runnable() { @Override public void run() { if (eventSink != null) { eventSink.success(o); } } }); }

Hi @uyit14

A new release was planned tomorrow because of the new version of the SDK for iOS, I will include this fix in this release.

Thanks.
