Miscellaneous problems signing application signatures?

In my project, I created an application that was modified later, when I try to install a new application, it requests a complete uninstall of the application. of the previous application, but I can’t do the same coz I can’t reuse the data left by the previous application , I can’t fix the signatures of different applications. . I can install it on a device without unistallation.

I'm to retain application data

[2012-05-23 19:09:56 - iCam] Re-installation failed due to different application signatures.
[2012-05-23 19:09:56 - iCam] You must perform a full uninstall of the application. WARNING: This will remove the application data!
[2012-05-23 19:09:56 - iCam] Please execute 'adb uninstall iCam.Cam' in a shell.
