Android App keep crashing at run time and import issue

Android App keep crashing at run time and import issue

My application keeps generating "unfortunately app has stopped working" on
my device. I've looked at my code and can't see any errors but I believe I
may have identified what my logcat files are complaining about.
Here is my logcat:

I have a strong feeling that it is going to complaining about this import:
import com.example.bluetooth.le.R;
I think for the import to stop generating that error my applications name
should be in place of the .le. So in my case it would read:
import com.example.bluetooth.samplebletest.R;
But I get an error telling me that the import cannot be resolved.
Is my crash related to this import? How can I fix it?
