how to know is signature of all versions is same or not?

Here is explain what happened: first I published my app(v1.0) in cafebazzar.ir store (my country's store). we works with debug version there. then I start to work for v1.1 but I corrupt app. so I deleted my project' directory and pasted it from Backup. then I make new version of my app and published it. but I don't know the signatures of versions is same or not? sorry for bad English.

Decompress your APK and get the file META-INF/CERT.RSA, than use keytool (you can find it inside bin directory of your JDK):

keytool -printcert -file META-INF/CERT.RSA

It returns the fingerprint of the certificate used to sign the APK
