title: Android Studio problems since the last update to 0.8 version
body: <p>I'm following the Google I/O conference and just a week before they announced that Android Studio 0.8 is available for downloading. Before that I used 0.6 and I was developing an application. Now I'm having both 0.6 and 0.8 on my Ubuntu. I added all the update from SDK for Android Watch and TV and all the Material Design stuffs. And today when I opened my project in the 0.8 version, after a few updates of some things, I'm receiving an error </p>
  
  <pre><code>Error:Execution failed for task ':app:processDebugManifest'.
  &gt; Manifest merger failed : uses-sdk:minSdkVersion 8 cannot be smaller than version L declared in library com.android.support:appcompat-v7:21.0.0-rc1
  </code></pre>
  
  <p>If someone has any idea what is this all about - share please. I tried to pull my project from my repository in GitHub, but without any result. Thank you.</p>
