title: Failed to install APK with INSTALL_FAILED_TEST_ONLY
body: <p>I'm using Android Studio 3.0.1 and the project I'm working on is using native code (C++).<br/>
  The problem is that the APK that Android Studio creates must be installed with -t (test) flag.<br/> I looked at <strong>Run</strong> view of Android Studio, and it's using -t and -r flag. With the -r flag I don't have problem, but how do I build <strong>Not</strong> test APK?<br/>
  I added android:testOnly="false" to the application tag in the Manifest, but it did not help.<br/><br/>
  Do you have any idea?<br/>
  Does it happen because I'm using native code?<br/>
  Can I add command to build.gradle to force it not to be test?</p>
