Samples Crash

I cant get the samples to run on my device.I'm trying the image targets sample.I ran NDK build command and got a libs folder with

 subfolders.

Fired up eclipse > File > New Project > Android > From existing source.

Cleaned and refreshed and it doesnt show any errors.The QCAR_SDK_ROOT variable also exists.However,when I run the application on my connected device ,screen goes black for a sec and then a message pops up saying the process has stopped unexpectedly and it force closes.

My Device - Samsung Galaxy Royal

A week ago ,I did get this sample to run but was facing problems with other samples.Then something weird happened.The SFK manager wouldnt show my installed android sdks.I'd 2.3.3 and 4.0 installed and it wouldnt show them!So I've reinstalled eclipse (a different version) and android SDK but now I cant even get this to work.

Any help will be appreciated.

Thank you.
