Question: Let's say we have strings\_test.xml, which stores string values for testing and should be shown in a debug-release. When the apk gets build as a release version all values should be change to an empty string e.g. `<string name="test_some_card_text">@string/empty</string>`.

Is there a possibility to achieve this?

As always, thanks in advance.

Answer: 
It is not possible to change the string value after creation of the apk.
But you can assing the value to text or edittext ... etx dynamically after creation of the apk.
For those who come here looking for some way to apply a similar method to `raw` resources, I dealt with it using `buildConfigField`.

```
gradle
...
buildTypes {
    debug {
        ...

        buildConfigField "int", "shared_resource_name", 'R.raw.debug_resource_name'

        ...
    }
    prod {
        ...

        buildConfigField "int", "shared_resource_name", 'R.raw.prod_resource_name'

        ...
    }
}

```

Pay attention to the quotes. After that, place `BuildConfig.shared_resource_name` in the files wherever `R.raw.resource_value` used to be accessed directly.

This can be used to other resources I think.
