title: Why android studio crashes automatically?
body: <p>My studio's current version is 0.9.9 (recently updated), now here is the history:</p>
  
  <p>There was some problems when I shifted eclipse to studio. The last problem happened when I updated it. My app became full of error. One of them was <code>cannot resolve Symbol ActionbarActivity</code>. And so many others. I spend a day behind it and gave up. I recreated my app from first to last with the same resources, then it became totally good to go. Three days later(today) again another problem raised. I turned on my laptop, opened Android studio and it says <code>Rendering problem No Android SDK found. Please configure an Android SDK.</code> But last night it was running fine. Now there is no design window. </p>
  
  <p>I am wondering that why the errors come automatically. I don't do anythings in the settings stuff of the studio. I just develop my app. I just write code and make my app. So whats wrong with the studio. It crashes without any reason and I have to waste the half of the time. Is this a kind of jokes? It too much irritating. Updating latest version is not the reason. The problem is occurring from whenever I downloaded the Android Studio and shifted from Eclipse to it. With 2 or 3 days intervals it comes with new problem.</p>
