how to test and debug all android device

how to test and debug all android device

A week ago,I developed a app and published to google play. App Link
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 .
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).
