Unable to run Linphone-android source code on actual device

Question

I have downloaded the Linphone-android source code using git clone. When I imported the source codes into eclipse, there were no errors found. I then tried to run the app on the actual device, however, the app was unable to load and it crashed. Here is the logcat of the errors. May I know how to resolve this issue? And what is causing this issue?
