How to check if apk is debug or release signed?
Is there any direct adb command to verify apk signature?
Tried the following dumpsys and aapt commands, but I am not able to find the exact flag
adb shell dumpsys package <package name>
aapt dump badging <apk file>
How to find out the given apk is debug or release signed? How to know which builds (user, userdebug or eng) we can install this apk?
If you want to check whether the apk is debuggable use the below aapt command.
aapt dump badging /path/to/apk | grep -c application-debuggable
Outputs 1: Debuggable Outputs 0: Not Debuggable.
i've tried a lot of stuff and came upon the following solution:
adb shell dumpsys package <package name> | findstr flags
if the build is debuggable, the "flags" line will have "DEBUGGABLE" parameter present. If it's not there, the build is not debug
You seem to be confused. Apks usually have debug and release versions. And eng, userdebug and user build types are used for the whole firmware images.
You can find build information (if properly populated by builder) by using
adb shell getprop ro.build.fingerprint
