A Correct answer
Explanation

The statement is True. All Android APK files must be signed with a certificate held by the developer. This is a fundamental security requirement - the Android system will not install an unsigned APK. Debug builds use a debug certificate, while release builds use a developer's production certificate.

AI explanation

Android requires every APK to be digitally signed with a certificate before it can be installed, and the developer must hold the private key for that certificate — this proves the app's authenticity and allows verifying that updates come from the same source. Without this signing requirement, the platform couldn't verify app integrity or origin.
