How can I exclude a folder upon compiling APK(Release)

just want to ask if how can I exclude a folder upon compiling a Release APK. I have this Resources folder filled with json files used for my simulations(Debug only) but would want to exclude this when compiling to a Release Apk.

Kindly see attached image Image.

You can use different assets folder, like:

app/src/main/assets
app/src/debug/assets
app/src/release/assets

Or you can define different src folders in the build.gradle file:

sourceSets {

        main.java.srcDirs = ['...']
        main.res.srcDirs = ['...']
        main.assets.srcDirs = ['...']
        debug.assets.srcDirs = ['...']
        flavor1.assets.srcDirs = ['...']
    }

To check the "debug" value you can use the default BuildConfig.DEBUG. In the same way you can define your own boolean value:

buildTypes {
        debug {
            buildConfigField "boolean", "MYVALUE", "true"
        }
        release {
            buildConfigField "boolean", "MYVALUE", "false"
        }
    }

The automatically-generated BuildConfig class will contain the following fields based on the directive above:

public class BuildConfig {
    // ... other generated fields ...
    public static final boolean MYVALUE = false;
}
