Full Stack Developer Needed to Resolve Andriod App Code

I had made one Andriod app through one developer.

It was working fine.

Suddenly it Stopped Displaying some dynamic content such as total amount and dedication and all.

I have its source code.

I need A developer who live near Bhayander / Thane. Who can visit Office and complete the work and resolve the errors ..

Or

She / he can work through anydesk to solve the error.
