问题
After updating SDK and installing build tools etc I'm not able to update the app. Although it works after uninstalling and re-installing, but that seems odd to me for the customers.
I also checked AndroidManifest, everything is OKAY, VersionCode, VersionName and Package etc.
Here are the logs:

回答1:
I had the same problem when I built my app with only V2 (Full APK Signature) option in Studio. I have now selected V1 (Jar Signature) and V2 (Full APK Signature) and it works.
回答2:
Select both v1 and v2 signatures worked like a charm for me on Android 6 !
Thank you @Droid Chris
I found the reason why on the android.com website
In Android 7.0, APKs can be verified according to the APK Signature Scheme v2 (v2 scheme) or JAR signing (v1 scheme). Older platforms ignore v2 signatures and only verify v1 signatures.
