Helluu there! 
I'm currently working on a Service, which reads all Contacts and their attributes (like name, phononumber, email, organization etc.) and writes them into a database.
I want the querying and writing to be done 1) the first time in the onCreate() Method and then 2) the next time whenever there is a change in the contacts list.
Now, how do I register a change? What can I use as a trigger to start the service?
Another example: For writing call-logs I used the trigger variable called 'PHONE_STATE' in the TelephonyManager class. The variable changes whenever a new call is made or comes in.
Comments and suggestions are welcome
