How to get BuildConfig values from xml?

Question

I have a xml file. In the xml file I want to get a BuildConfig value. BuildConfig value is set in build.gradle.

   <?xml version="1.0" encoding="utf-8"?>
<resources>
   <string name="com_my_api_key">**REPLACE_WITH_YOUR_API_KEY**</string>
</resources>

I want to get that api Key from buildConfig, similar to how I get those values in the java code.

  public class MyApp extends Application{

      public String APPTIMIZE_KEY = BuildConfig.APPTIMIZE_KEY;

 }

Here is the value being set in build.gradle, its coming from an external file.

   release {
        buildConfigField "boolean", "APP_DEBUG", "false"
        buildConfigField "String", "APPTIMIZE_KEY", "\"${props.getProperty("apptimizeKey_App1")}\""

How do i reference this ---> BuildConfig.APPTIMIZE_KEY in the xml file to get it?

There is a lightly documented resValue counterpart to buildConfigField. I haven't tried it yet, but something along the lines of this would be where I would start:

resValue "string", "com_my_api_key", "\"${props.getProperty("apptimizeKey_App1")}\""

This would go alongside your existing buildConfigField, if you need/want that value to also be accessible from BuildConfig. You would no longer need to manually declare the string resource, but instead it would be generated for you.
