what are the steps to run the andriod appl on my mobile phone

i want to run the application i developed in eclipse on my mobile phone.i have installed the respective USB Drivers required.
what has to be done after that?

Not sure how Eclipse does it, but the SDK has the "adb" command for that: http://developer.android.com/guide/developing/tools/adb.html

In the same way you run it on the emulator. Go to run configuration from eclipse and then target, if your phone is attached and connected properly, it will show the phone there, select that and run, and probably you have to set the debuggable attribute to true in android manifest.

Try following these,

1. Enable USB Debugging in your phone. Settings -> Applications -> Developer -> USB Debugging
2. Don't mount your USB memory while connected to your PC
3. Check whether you have installed all the necessary drivers in your PC. (If not try using Samsung Kies if you are using a Samsung device)

Note : Don't forget to enable Manual run configuration in your Eclipse ;)
