Google Play console reporting crashes from unreleased applications

As we are interested in publishing only release applications, we may adopt following strategy to get rid of messing up crash reports :

./build.gradle :

android {
    ...
    defaultConfig {
        applicationId "my.app.package"
        ...
    }
    ...
    buildTypes {
        release {
            ...
        }
        debug {
            ...
            applicationIdSuffix ".dev"
        }
    }
...
}
