Dear Android community, I'm having a big problem with the application certificates and I haven't found any official info regarding the possibility of signing an application with more than one certificate. I have an application with package name "com.example.myapp" signed with certificate A and the same app with the same package name but signed with certificate B. The application signed with A comes preinstalled in device X and the app signed with B comes preinstalled in device Y.
Now I need to publish a the app in the Market with the next version. How can I publish this update so I don't leave any of my users hanging. If i sign the update with certificate A, only users with the device X will be able to install the update and the same thing with certificate B and device Y. I saw some posts from other developers in different forums and groups saying that it's possible to sign an apk with two certificates. When I try this I get the worst result possible, device X nor device Y can install the update. Another thing, is it possible to do some kind of device differentiation in the Market so users with device X can download one app and the users with device Y the other? Thank you all in advance. I hope you can help me with this issue. Cheers, Jalal -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
