I'm struggling to work out what you are trying to do...
Are you saying that you've got a keystore file already, but that you can't get your App, in B4A to use the keystore file that you've already created?
yes ,i you've got a b4a keystore, and build apk with b4a,signed with this keystore.
but someone use my app as his.
the app store get me a apk and let me to sign with my keystore to prove i was the owner of the keystroe to get my app back.
but i try to sign it like "
jarsigner -verbose -keystore d:\keystore -sigalg SHA1withDSA -signedjar d:\signed.apk d:\unsign.apk b4a
", the app store say that them can not match.
can you catch me?
