Difference between signature versions - V1 (Jar Signature) and V2 (Full APK Signature) while generating a signed APK in Android Studio?

Question

Please select at least one of the signature versions to use in Android Studio 2.3

Now while generating a signed APK in Android Studio, it\'s showing

Answer 1

It is written here that "By default, Android Studio 2.2 and the Android Plugin for Gradle 2.2 sign your app using both APK Signature Scheme v2 and the traditional signing scheme, which uses JAR signing."

As it seems that these new checkboxes appeared with Android 2.3, I understand that my previous versions of Android Studio (at least the 2.2) did sign with both signatures. So, to continue as I did before, I think that it is better to check both checkboxes.

EDIT March 31st, 2017 : submitted several apps with both signatures => no problem :)
