Problem with signing app

[sumo22]

Hi,
I have a big problem with signing my application. I cannot generate a new key.jks. When I do this, I always get an error saving the key. Android Studio and APK Editor Studio are affected. I cannot sign the application in any of these programs. I really don't know how to do this. All descriptions do not provide for the problems I have encountered. Additionally, there is a problem in Android Studio with the Gradle plugin which I cannot update. Attempts to reinstall the program do nothing. Any tips? I am not a programmer and I do everything by trial and error.

APK signing with Google Play

I am trying to publish a new AI2 APP like I already did 8 others in the past; I got this: “You imported a signed APK or Android App Bundle with a key that is also used to sign APKs given to users. Since you are registered with the Google Play app signing system, you must sign your APK or Android App Bundle with a new key before importing it.” • I haven’t change my Google account • I compiled the APP as usual • I understand that the keystore is built-in and we do not control • However in this A…

Ok. I finally found the solution. I found it on github, and it's:

Sign android app with new keystore file if you missing password or lost jks file.

1. Create new keystore.jks file with comand line (not android studio build menu)Linux: keytool -genkeypair -alias upload -keyalg RSA -keysize 2048 -validity 9125 -keystore keystore.jks Windows: "C:\Program Files\Android\Android Studio\jre\bin\keytool.exe" -genkeypair -alias upload -keyalg RSA -keysize 2048 -validity 9125 -keystore "C:\keystore_new.jks"
2. Generate a .pem file from new keystoreLinux: keytool -export -rfc -alias upload -file upload_certificate.pem -keystore keystore.jks Windows: "C:\Program Files\Android\Android Studio\jre\bin\keytool.exe" -export -rfc -alias upload -file "C:\upload_cert.pem" -keystore "C:\keystore_new.jks"
3. Use this support form, set "keystore problem" and with attachment add .pem file: General Play Console issues - Play Console Help
4. 12-48h you new keystore is enabled. Update your app on playstore with new apk signed with new keystore

Error al compilar mi aplicación! Keystore Personalizado!

MIT App Inventor default values for keystore and if you have anything else it will not work… Default Keystore Password - android Default Key Password - android Default Keystore Alias - androidkey
