You need to use B4ABuilder to compile an unsigned apk.

"C:\Program Files (x86)\Anywhere Software\Basic4Android\B4ABuilder.exe" -Task=Build -NoSign=True -Obfuscate=true

Then you use jarsigner and zipalign.

Follow these steps:
- Close the IDE
- Go to: C:\Users\<user name>\AppData\Roaming\Anywhere Software\Basic4android
- Open the INI file
- Change the keystore alias (SignKeyAlias property)

There is no such a folder in my computer. My user name contains characters like ş and ı. This can be the reason? And where can I see this folder?

When I try to do item 6, I receive an error below. Can iı be because of wrong username? Or the problem is different? What should I do?

'jarsigner" is not recognized as an internal or external command
