You need permission to access contacts
Try adding

Syntax: [ Download ] [ Hide ]

Using xml Syntax Highlighting

<uses-permission id="android.permission.READ_CONTACTS" />
Parsed in 0.000 seconds,  using GeSHi 1.0.8.4

to the Androidmainfest file.
using permissions are documented here

There are no LocationProviders visible for your application ... and thats the reason why "providers.get(0)" leads to an error.

You need to add some some permissions to your AndroidManifest.xml to be allowed to use the gps-service:
