APK Feature Logic Update

Job ID: 40396472

Budget: $10 – $30 USD

I need an experienced Android developer to step into an existing APK and focus solely on functionality updates. The user interface stays exactly as it is; what I need is the underlying logic refreshed so the current features behave correctly and more efficiently.

Your task is to modify the existing features—no new screens, no fresh UI elements—just solid refactoring and enhancement of the core code. That means tracing the present workflows, identifying where the logic falls short, and rewriting or optimising those sections so everything runs smoothly on modern devices and recent Android versions.

Deliverables are straightforward:
• A rebuilt APK and matching source code with the updated logic in place.
• A concise changelog explaining what was touched, why, and how it improves behaviour.
• Confirmation the app compiles cleanly in Android Studio and passes its current test cases.

If you have a knack for clean, maintainable code and a sharp eye for subtle behavioural bugs, this should be a quick, focused engagement.


I have an apk file. When you install on a phone, it listens for requests from adb. then it tries to connect external https domain. It uses a certificate.

I want to manipulate as this domain. i changed hostname file and forward these requests to my server. i can handle requests. I can try to send response but, i get SSL error.

Software uses its own ssl pinning.

I want to modify apk file. to remove ssl request and send not this domain and put my server ip instead of it
