I’m looking for an Android developer who can build a lightweight calculator that handles the four basic operations—addition, subtraction, multiplication and division—and nothing more. The interface can be straightforward; it just needs to look clean on both phones and tablets and pass Play Console requirements without extra permissions. I will give you my AdMob App ID and individual Ad Unit IDs. Please wire them up so ads display properly in the released build and comply with Google policy. When you hand the project back, I need: • A signed, release-ready APK • The corresponding AAB file for Play Console • The complete, well-organised Android Studio source code Everything should compile out of the box and be ready for direct upload to Google Play. Let me know how long you’ll need and your total price, then we can get started right away.
