Error in "Firing the intent" segment

something confusing is happening here:
At the beginning i wrote this code on the criminal Intent version in which i write the challenges segments, and this code did not work, later i wrote it again on the regular project and it worked.

maybe there is a problem with the manifest uses premission (which i added in Challenge 15 ) which i am not aware about ?

this is the exception which was showen:

help will be much appreciated

Can you please paste the AndroidManifest.xml file?
