The error clearly states that you need to remove installed application from your device and install it again. If it doesn't work, try to enable proguard for your release/debug builds:

buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
    debug {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

You need to add this code into the build.gradle file, inside the section called android. More info on Gradle in Android Studio can be found here.
