I need a fresh, fully-functional digital signing key that lets me compile and distribute my own Android apps without any “unknown publisher” warnings. Think of the certificate Google Play assigns when an APK is uploaded: that’s the result I’m after, but held entirely under my control.
What I expect from you
• A unique keystore file (.jks or .keystore) with its private key, never shared or reused elsewhere.
• Alias name, password, and SHA-1 / SHA-256 fingerprints so I can register the key with Firebase and other Google services.
• A brief, step-by-step note showing how to plug the file into Android Studio or a Gradle build and produce a properly signed APK/AAB.
• Proof the certificate is valid (for example, an unsigned test APK that you then sign with the key and install successfully).
Acceptance criteria
I’ll consider the job complete once I can build an app with the provided key, install it on a physical Android device, and see the install proceed without signature errors.
If you’re also able to generate a comparable certificate for iOS down the line, let me know—that could lead to a follow-up task, but right now the Android keystore is the priority.
