body: <p>The following code returns this warning in Kotlin project using Android studio 3.0 on Mac.</p>
  
  <pre><code>private val REQUEST_CODE = 11 
  private val TAG = "RecentCallsActivity"
  </code></pre>
  
  <p>Private property name 'REQUEST_CODE' doesn't match regex '<code>_?[a-z][A-Za-z\d]*</code>' less... (⌘F1)
  <strong>Reports private property names that do not follow the recommended naming conventions.</strong></p>
  
  <p>What is the recommended naming convention ?</p>
  
  <p>I found , a similar <a href="https://stackoverflow.com/questions/38951610/local-variable-or-instance-field-name-doesnt-match-regex-a-z#">question</a>,  that answers how to disable the same.</p>

  <p><strong>Update:</strong> In some examples , I have seen this usage which removes the warning.</p>
  
  <pre><code>class KotlinExampleActivity : Activity() {
  
  companion object {
      val TAG: String = KotlinExampleActivity::class.java.simpleName
  }
  </code></pre>
