Dear team,

We are developing an application with Taplinx. And we got this error:

 This happens seconds after initialization and 

libInstance.isActivityRegistered() == true;

After a few seconds, and before any card intent, it crashes with the fatal error above.

Since the application will not be distributed online and the users' locations will be in Mainland China, we don't want to include Firebase in our application. Are there any methods to avoid this? Could you offer some suggestions on this error?

Thank you very much, and I look forward to your reply.

Warm regards,

Hello sir,

It is possible to avoid the use of Firebase but unfortunately, these implementations need to be done by your development team. I am very sorry but since TapLinx does depend on Firebase for some implementations, the removal of these dependencies will have to be done manually starting by a clean Android project and avid the imports of any google and firebase module.

I am very sorry but we don't have any guide for performing these changes.

Quick updates, I found the requirements of including the library of Firebase in the quickstart. Then I still need some suggestions on: If I include the Firebase in my project without access to Firebase (due to the internet restrictions), will this matter?

[Gralin]

Yes, it will work wihtout Firebase, but you need to include the library

com.google.firebase:firebase-core

On runtime, you may see these errors in logcat, but those are harmless
