I’m looking for an experienced Android developer to build a small utility APK that does just three things: • Forward incoming calls to a number I can set inside the app • Send a custom SMS on demand (simple text field + send button) • Delete selected SMS threads from the device No user-login or authentication is needed—the app opens straight to the main screen where these actions are available. A clean, minimal UI is fine; reliability of the underlying telephony and SMS functions is the priority. Please target modern Android versions while keeping backward compatibility where practical, and deliver both the signed APK and full source code (Java or Kotlin) with brief build instructions so I can recompile if needed.
