Good morning, I am trying to compile my android project in Windows since the development of it was in Linux but when trying to run the application I get this message.
I do not know if something similar ever happened to someone.
Actually it is not a problem that affects your application, what happens is that the .apk that tries to upload to your device is different version to the installed, mainly it can be a signed version for production that tries to be replaced with a development application signed with the Keystore debug.
WARNING: Uninstalling will remove the application data!
Do you want to unistall the existing application?
Just select yes and replace it.
This is an example, I have an application installed from Google Play, signed with a specific Keystore for the store, but I try to upload the same application to my device (it's the same application when it has the same package id), it shows me the message:
When installing the application the next time I would not show the message. It even happens if the application was uploaded to another pc since it "signed" with another debug keystore.
