Question

Android

Hello. I am writing an android application that should display a list of all calls made, their date and time. Tell me, please, how can I access the data of the phone book and calls? Where do I begin?

From reading documentation

Cursor cursor = contentResolver.query(CallLog.Calls.CONTENT_URI,
    new String [] {Calls._ID, Calls.NUMBER, Calls.DURATION, Calls.TYPE},
    null, null, Calls.DATE + " DESC ");
