If you cannot sign the apk in Android Studio, manually signed it with

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my-release-key.keystore my_application.apk alias_name

if you not have the key, generated it with keytool -genkey -v -keystore my-release-key.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 10000

You also can manually signed as the manual do:

keytool -genkey -v -keystore my-release-key.jks-keyalg RSA -keysize 2048 -validity 10000 -alias app
zipalign -v -p 4 my-app-unaligned.apk my-app.apk
apksigner sign --ks my-release-key.jks my-app.apk

check the signed apk

apksigner verify my-app.apk
