title: How to make sure an Android App works on most smartphones?
body: <p>How can i make sure that my android app works on majority of the devices in the market. What testing tools do i have to use? Obviously if there are 12 or more smartphones in the market then i cannot buy each of them to test my app.So what should i do? Wonder if "Dvice Anywhere"(<a href="http://www.deviceanywhere.com/" rel="nofollow noreferrer">http://www.deviceanywhere.com/</a>) can help us in this regard?</p>
  
  <p>Does firmware or OS version also matters (1.5,1.6, 2.0, etc.)? </p>
  
  <p>Please comment and explain.</p>
