How do I find out if my current build is signed?

Question

I want to perform a code operation only under the assumption that the current build is a signed APK. Is there a way to programmatically find out?

Could this be the answer? https://stackoverflow.com/questions/32954404/verifying-an-apk-programmatically-using-jarsigner — Daniel, Mar 07 '18 at 15:13

You can check to see if you're running a debug build with BuildConfig.DEBUG. If this shows up as false, you're on a release build. For example:

if (BuildConfig.DEBUG) {
    Log.d(TAG, "This is a debug build");
} else {
    Log.d(TAG, "This is a release build");
}

The question is about signed/unsigned. not about release or debug. – Sreekanth Karumanaghat Apr 08 '20 at 09:14

PackageInfo.signatures contains the array of all signatures read from the package file. This can be obtained using PackageManager.getInstalledPackages() with GET_SIGNATURES flag.
