Unable to run my app from Android Gingerbread 2.3.9 Phone

Hi friends
I am using Android 10 Gingerbread 2.3.9 version . I have tested my app on Emulator using Eclipse it works fine . Now I want to test my app on real device. For 

that I have googled a lot and found that we need to Download the Google USB Driver package from SDK Manager. 

I have downloaded and Update my driver from Device manager then it says Your driver is Updated Successfully. When I plug my Phone to PC in device manager I got 2 options like Spreadtrum Phone and  a Android Phone I have updated the driver for Android Phone and for the Spreadtrum Phone it shows a Yellow bar near left bottom corner. I dono what it was and googled to find a driver to update it also but could not figured out. I left that part and tried in another way.

I have connected my Phone to my PC and then copy the .apk file into my SD Card and then unplug the cable from my pc. then I click on my .apk file. I was 

unable to run and it gives me a messages says "There was a problem in parsing the Package".

so I thought to try to debug the app from eclipse when phone is connected. I have chosen the option as "Allow me to Pick a device every time" from Run 

Configurations". But I am unable to see my device in my Devices list also I tried from Command prompt "adb devices" it is not listed my phone which I 

connected.  I have Checked 'Unknown Resources" and also Checked " Use Debugging" in Developement menu option. but nothing solves my problem.

I have tried a lot of code samples and every one is doing in the same way but I could not figure out the problem. 
Please friends tell me what is the problem as I am not able to debug from my eclipse I can't figure out the problem from LogCat also.

Thanks
Ganesh
