Question

Is there a way to access the Dialer/Contacts/Call Log of Android through an application?
I essentially want to add features/information, and I know that those databases are unable to be changed past queries and insertions, so I was wondering how to override the stock Dialer/Contacts/Call Log? Preferably, I’d only like to change one of those, but any info will help.

Query android.provider.CallLog.Calls.CONTENT_URI for getting Callogs as:

String[] strFields = {
        android.provider.CallLog.Calls.NUMBER, 
        android.provider.CallLog.Calls.TYPE,
        android.provider.CallLog.Calls.CACHED_NAME,
        android.provider.CallLog.Calls.CACHED_NUMBER_TYPE
        };
String strOrder = android.provider.CallLog.Calls.DATE + " DESC"; 

Cursor mCallCursor = getContentResolver().query(
        android.provider.CallLog.Calls.CONTENT_URI,
        strFields,
        null,
        null,
        strOrder
        );

and in manifest.xml add:

<uses-permission android:name="android.permission.READ_CONTACTS"></uses-permission>
