Changing only Application ID, not package name

Question

I only want to change application id in gradle file, but dont want to change package name.
Is it possible?

It is not recommended to change your application id. What you can do is change your application suffix.

As an example, if your application id is com.example.my_app then add different suffixes for different build types, such as com.example.myapp.dev for debug.

Go to app/build.gradle file and on android block add the suffix you want:

buildTypes {
        release {
            applicationIdSuffix ".production"
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        debug {
            applicationIdSuffix ".dev"
            versionNameSuffix '-DEBUG'
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
