Android studio installing the app over another app

Question

I’ve been using the same apk to perfect it, went to the folder and gave a Ctrl v Ctrl c and started editing the new apk. I changed the name, the name of the folders, I changed some screens, only when I emulate on the phone it installs over what I had already done.

How to fix this?

Answer 1

What identifies the App is yours applicationId:

In his build.Gradle :

 defaultConfig {
        applicationId "com.me.pacote.exemplo"
        minSdkVersion 14
        targetSdkVersion 23
        versionCode 1
        versionName "1.0.0"
    }

Change the applicationId to manage another app.
