title: Debugging application gives me a red line
body: <p>On Manifest, I get an error for Debugging </p>
  
  <pre><code>&lt;application
  android:allowBackup="true"
  android:icon="@drawable/ic_launcher"
  android:label="@string/app_name"
  android:debuggable="false"&gt;
  </code></pre>
  
  <p>I am trying click for apk in Android tools >> Export signed Application Package" but I don't know how I got an error.
  The Lint Warning for it "Avoid hardcoding the debug mode; leaving it out allows debug and release builds to automatically assign one"</p>
  
  <p>Can anyone help?</p>
