Signer ERROR (APK Signature Scheme v2 signer #0)



Hello Team,

I am facing an error when uploading a new version of my app on the Play
Store, whereas I have already successfully released previous version of
my app before.

Here is the error : You uploaded an APK with an invalid signature
(learn more about signing). Error from apksigner: ERROR (Jar signer
CERT.RSA): No APK Signature Scheme v2 signature from this signer ERROR
(APK Signature Scheme v2 signer #0): No JAR signature from this signer.

I am sure that my relase key is the right one, because this is the
one that I used to publish previous version. This issue is similar to #924
but this thread has not helped me fixing this issue. I havent changed
my Android Manifest since my last release except the
Following is how I am generating signed apk:

tns build android --release --key-store-path myApp.keystore
–key-store-password myPassword --key-store-alias myAlias
–key-store-alias-password myPassword --copy-to myAppp.apk
The app was made with NativeScript 3.4 Vanilla.

For Non Nativescript Android applications Android Studio gives you
option to select both V1 and V2 signatures but we don’t have a control
over these in nativescript. Is there any way how we can control this?

Can someone please guide me?



I had also raised this issue with Google Support team and they fixed this from their end so nothing to be done from Nativescript side.


but foe me it was working smooth on my android phone when it was running on android version 6.0.1 however as I have updated to android version 7.1.1 whenever now I am opening the app it only loads a blank screen on the start up and crashes after a while automatically. How do I fix it?
