title: Instant run doesn't work due to "multiple process"
body: <p>After having configured instant run, the run button has a small yellow thunderbolt.But while I run the app, Android Studio still performed a full build &amp; install, full message is listed in the picture.</p>
  
  <p>I've searched the official documents in <a href="http://tools.android.com/tech-docs/instant-run" rel="noreferrer">http://tools.android.com/tech-docs/instant-run</a> , but there wasn't anything about "multiple process".I wonder "multiple processes" means compiling or my android app.</p>
  
  <p>What should I configure to turn off multiple processes and experience instant run ?</p>
