Hello,
I have gone through your requirements, you want us to check in your code that if subscription functionality is working or not. as you tell there is 30 day free subscription trial.
So, Yes I am able to look into code & find if code is working or not.
I will lower that 30 days time period to some hour & can confirm that if its working or not
If not working than I will fix that issue & send you working model.
Let me tell you about myself, I am fresher on this platform but I have worked on more than 25 android applications in four and half years of my professional career.
I have expertise in android development, full knowledge of Android life cycle - Material design - REST api - Sqlite database - Payment integration - Third party library integration - Background services.
One more thing I am full time freelancer so will always available for support and communication.
Let me know if you are interested, I am ready to discuss everything before you award me this task.
Thanks,
Hardip
