Google play shows error code 504 for Android N preview

I developed an app and published it on the Play store, but some users experienced problem with install from store. They get an error code 504 during installation. The problem occurs only on Android N devices. Does anybody has same issue?

UPDATE:

After install Android N device gives me this log error:

-24 20:29:32.941 4736-6127/? E/PackageInstaller: Commit of session  1647022075 failed: Failed to collect certificates from    /data/app/vmdl1647022075.tmp/com.xxx: META-INF/CERT.SF indicates /data/app/vmdl1647022075.tmp/com.xxx is signed using APK Signature Scheme v2, but no such signature was found. Signature stripped?

but no such signature was found. Signature stripped?

Any ideas?

Add this to the app-level build.gradle:

android {
    signingConfigs {
        defaultConfig{
            v2SigningEnabled false
        }
    }
}

"defaultConfig" is the default product flavor. If you have other flavors, you should add them likewise:

android {
    signingConfigs {
        flavor1{
            v2SigningEnabled false
        }
        flavor2{
            v2SigningEnabled false
        }
    }
}

Not sure what flavors you have? You can discover them in Android Studio by clicking Build > Edit Flavors.They will be listed in the middle column.

Android N introduces APK Signature Scheme v2 and Android Studio 2.2 use it by default. If you have build problem as I do just add

v2SigningEnabled false

in the build.gradle app level file.
