Purpose of Android app signing and keystore contents
WHAT IT TESTS: App identity on Android. ANSWER OUTLINE: Signing proves authorship and integrity, enables same-key updates, and binds app identity; a keystore holds private keys and certificates.
WHAT IT TESTS: Whether you understand how Android establishes app identity and trust. ANSWER OUTLINE: A strong answer explains that signing proves authorship and ensures APK integrity; Android uses the certificate to enforce same-key updates and signature permissions; a keystore is a container that holds one or more private keys and public-key certificates. RED FLAG: Confusing signing with obfuscation, claiming the keystore stores passwords or APKs, or omitting the update-enforcement requirement.
