title: RingCaptcha SDK import into android studio shows two app icons
body: <p>I have added ringcaptcha sdk using android studio in my app. But after adding ring captcha sdk app shows two icons(My app and Ringcaptcha Sample).
  How can I remove second app icon?
  I have added following maven repository(url '<a href="http://ringcaptcha.github.io/ringcaptcha-android" rel="nofollow">http://ringcaptcha.github.io/ringcaptcha-android</a>').
  Also added dependencies (compile 'com.thrivecom:ringcaptcha:1.0.7@aar')</p>
