I have created two android apps that look the same. One was built using XML a few years ago, which I named app A. I also created a signing key for it to generate a signed build. The other one, app B, was built using Compose and I created it a few months ago.
Now, I would like to update app A with the Compose version, but I encountered an issue. Both projects have the same application ID, and I am using the same signing key for app B. I am able to generate a signed build for app B, but when I try to update the app, I receive an error message saying "Package 'com.test.test' signatures do not match the previously installed version," and the device displays "Something went wrong. App not installed."
Can anyone provide some assistance on how to resolve this issue? I would greatly appreciate any help.
