title: how to test and debug all android device
body: <p>A week ago,I developed a app and published to google play.
  <a href="https://play.google.com/store/apps/details?id=com.tiny.fakeapp" rel="nofollow" title="link">App Link</a></p>
  
  <p>This app use camera and activity-alias . It works fine in my phones(S1,S2,New One,Sony Xperia v). But after i published to google play , i found many problems,like HTC one x camera  or HTC butterfly activity-alias not working in my app . I dont have these phones ,so its hard to debug . </p>
  
  <p>Is there a good way to solve this situation ? I used some test websites like appThwack   and Keynote. But it only response me error message, I am hard to debug too,because it need to upload apk to test(spend long time).</p>
