Hi Mohammed,

I have couple of questions with regards to the steps that you have followed:

1. Were you able to reproduce the same issue using our sample app? If not, can you send us a sample app that demonstrates the issue. 
2. Did you configure the Gradle file to reference Google Play Services as a dependency into the your project?  

Thanks,

Hi Veer,

A1. The sample is working fine with no issues.

A2. Yes I did configure the Gradle file to reference Google Play Services as a dependency into my project.

I'll try to send you a sample soon

thank you for your concern
