title: How to set buildConfigField for module from outside for android?
body: <p>I am developing in Android, and I have a submodule in my project.</p>
  
  <p>I have set <code>buildConfigField</code> like the following in <code>build.gradle</code> of Module</p>
  
  <pre><code>buildTypes {
      release {
          minifyEnabled false
          buildConfigField "String", "TestId", '"48"'
      }
      dev {
          buildConfigField "String", "TestId", '"88"'
      }
  }
  </code></pre>
  
  <p>And I use <code>TestId</code> in module.</p>
  
  <p>But I want to change the <code>TestId</code> from outside, like <code>build.gradle</code> of <code>app</code>.</p>
  
  <p>How to set the <code>buildConfigField</code> of module from <code>build.gradle</code> of <code>app</code> for Android ?</p>
  
  <p>Thanks in advance. </p>
