Understanding Code Transparency introduced in Android 13
The code transparency file is propagated to the base APK built from the app bundle (specifically to the main split of the base module).
It can then be verified that:
- The DEX files which are present in the files are checked.
- The public key which Google Play generates is acquired for step 3,
- When we combine the logic of both the DEX values and the public key which is available we can check if ever the signature was compromised or not.
Code Transparency For App Bundles in Android 13
Before shipping any new apps, you may want to have a better understanding of how things will work if you can have better code transparency to deliver your app bundles to the user. Perhaps a better signing mechanism or something like that in place. For apps released using the Android App Bundle, code transparency is an optional code signing and verification approach. It makes use of a signing key for code transparency that is only owned by the app developer. You can sign in your code with the native method which is built into the Android Studio, or you may alternatively enroll yourself in Google Play Signing, but altogether, you need to sign up your app before it gets to the public, and for that Android 13 can help you by adding more transparency. In this Geeks for Geeks article we will learn how you can adopt this new mechanism.
