installing non market app on samsung galaxy tab 10.1

---

Hi folks,

I'd developed an android app v2.2 using Eclipse 3.5 and it's running on Android Emulator.Now I want to test the same .apk on Samsung Galaxy Tab 10.1.How to install and run non market .apk on this device.

I've tried as you said but still I'm having following doubts.

1)Moved the apk to your phone via USB, and then installed it in the normal fashion.But it's being crashed on startup activity of my app while it's running properly on emulator.

2)Directly connected Tab via USB to my PC.But when I run 'adb devices',my Tab's not being listed while I can easily install and run it on emulator for the same.

Any other way to install apk using ADB to Tab?
Is there any possibility of having any OS versioning / memory issue?
(apk version's 2.2 while my Tab's having 3.1)

Kindly suggest solution for the same ASAP.
