Android Question Keystore File

[gerredtor]

Hello,

My old Keystore File has the data format .dat, i cant choose it.
It doesnt show up in the File Dialog

Have you tried to rename the file and give it a new extension?
Change extension from .dat to .keystore

Yes but than comes the error:

Keystore was tampered

And we think the password is correct

did you update b4a to a newer version?
Maybe @Erel can give another help on this.

Yes my B4A version is the newest, but the key was created with PhoneGap

 

[DonManfred]

I don´t know whether those keys are compatible.

It seems that you need to sign your app the same way like phonegap did i guess.
i remember to read a post somewhere here in forum in the past where a user was searching for a way to sign his app with the key from a customer, not his own signkey.
But i don´t know exactly.... There is just "something, somewhere in my brain"

Edit: Look here. Maybe this is of help
