APK upload failed for Alpha version. Errors from apksigner: Digest algorithm and Signature Algorithm Which is not supported on API levels [[16, 17]]

问题

I had signed the APK by using keytool, jarsigner, and zipalign utlities.

I have used the following commands:

keytool -genkey -v -keystore myAppTransporterKey.keystore -alias myTransporter -keyalg RSA -keysize 2048 -validity 10000

cordova plugin rm cordova-plugin-console

cordova build --release android

jarsigner -verbose -keystore C:\Users\ali\Documents\transporterApp\myAppKey.keystore C:\Users\ali\Documents\transporterApp\platforms\android\build\outputs\apk\android-release-unsigned.apk myTransporter


jarsigner -verify C:\Users\ali\Documents\transporterApp\platforms\android\build\outputs\apk\android-release-unsigned.apk

After running:

jarsigner -verify -verbose -certs C:\Users\ali\Documents\transporterApp\platforms\android\build\outputs\apk\android-release-unsigned.apk

getting this message: jar verified

After running:

zipalign -v 4 C:\Users\ali\Documents\transporterApp\platforms\android\build\outputs\apk\android-release-unsigned.apk C:\Users\ali\Documents\transporterApp\platforms\android\build\outputs\apk\myTransporter-Final.apk

get the message: Verification succesful

After uploading to ALPAH in Google play console I am getting following error

Upload new APK to Alpha

Uploading

You have uploaded an APK with an invalid signature ( read more about signing ). Errors from apksigner: ERROR (Jar signer D2DTRANS.RSA): JAR signature META-INF / D2DTRANS.RSA uses digest algorithm 2.16.840.1.101.3.4.2.1 and Signature Algorithm 1.2.840.113549.1.1.1 Which is not supported on API levels [[16, 17]]

You need these stepps :

1) jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore C:\Users\ali\Documents\transporterApp\myAppKey.keystore C:\Users\ali\Documents\transporterApp\platforms\android\build\outputs\apk\android-release-unsigned.apk myTransporter

2) jarsigner -verify C:\Users\ali\Documents\transporterApp\platforms\android\build\outputs\apk\android-release-unsigned.apk

3) zipalign -v 4 C:\Users\ali\Documents\transporterApp\platforms\android\build\outputs\apk\android-release-unsigned.apk C:\Users\ali\Documents\transporterApp\platforms\android\build\outputs\apk\myTransporter-Final.apk

Hope this will help you ^^

You need these steps:

zipalign -v 4 C:\Users\ali\Documents\transporterApp\platforms\android\build\outputs\apk\android-release-unsigned.apk C:\Users\ali\Documents\transporterApp\platforms\android\build\outputs\apk\android-release-unsigned-aligned.apk

apksigner sign --ks C:\Users\ali\Documents\transporterApp\myAppKey.keystore --ks-pass pass:[PASSWORD] --key-pass pass:[PASSWORD] --out C:\Users\ali\Documents\transporterApp\platforms\android\build\outputs\apk\android-release-singned.apk C:\Users\ali\Documents\transporterApp\platforms\android\build\outputs\apk\android-release-unsigned-aligned.apk

To sign applications use the BuildTools 24.0.3

According to the official documentation, you can perform the following steps:

1. generate the .apk file
2. Align data: zipalign -v -p 4 my-app-unsigned.apk my-app-unsigned-aligned.apk
3. Sign the APK: apksigner sign --ks my-release-key.jks --out my-app-release.apk my-app-unsigned-aligned.apk

You may need to define the type of the keystore with the --ks-type option:

~/Android/Sdk/build-tools/26.0.2/apksigner sign --ks-type pkcs12 --ks ~/[…].p12 \
--out android-release-signed-aligned.apk android-release-unsigned-aligned.apk

回答4:

This is fixed in apksigner 0.8 which was released in Android SDK Build Tools 26.0.2.

If any issue persists, please report at Google issue tracker they will re-open to examine.
