I need to view the certificate of an Android APK, however when I look in the META-INF folder, there is no CERT.RSA file. I know that somehow the APK must be signed, because I was able to put it on an android emulator and run it, and Android won't install any unsigned apps, so it must be signed. I just really need to actually see the signature but I cannot find it.
I am using Android Studio.
Any help would be greatly appreciated. Thanks!
