As per your question,

the device is- Samsung Galaxy tab 3. Model No- GT-P5210, Android Version - 4.4.2.

                Yes, it is crashing for  Kitkat and lower version.

                Yes, it is reproducing on the same device all the time.

                 Currently, I don't have any other similar device.

Thanks & Regards

Hi there,

 

Thank you for providing the requested details in private.

 

It seems that there might be an issue with using MultiDex on an old Android version for your app. If you are using MultiDex, could you then kindly try the solution suggested here, and confirm whether or not it would work on your end?

 

If the situation persists despite the above (or if you weren't using MultiDex in the first place), could you then send the details below (via Reply privately to author) so that I can further investigate the issue?

• Copy of your sample project (replicating the issue)
• Steps to replicate the issue

 

Regards,

Ziv Yves Sanchez

Thanks, this trick has solved my problem.

I hope google will bring some workaround for it in the near future.
