Post 6: Xamarin : Displaying the Call Log

Displaying the Call Log

Android Versions: Level 1 and above
Permissions: android.permission.READ_CONTACTS

All the call activities on your phone are logged in the call_log content provider. Therefore, if you want details about all the incoming, outgoing, or missed calls, you can query the content provider to get them. This post shows you how easy it is.

To get the call log details, query the call_log content provider, iterating through the results by using a Cursor object. The following code snippet retrieves all the call details and sorts them by date. It then prints out the details of each call — ID, phone number, date of call and type of call

 
public void  GetCallLogs(){

            // filter call logs by type = missed
            // string queryFilter = String.Format ("{0}={1}", CallLog.Calls.Type, (int)CallType.Missed);

            // filter in desc order limit by 3
            // string querySorter = String.Format ("{0} desc limit 3", CallLog.Calls.Date);

            // filter in desc order limit by no
            string querySorter = String.Format ("{0} desc ", CallLog.Calls.Date);

            // CallLog.Calls.ContentUri is the path where data is saved
            Android.Database.ICursor queryData = ContentResolver.Query (CallLog.Calls.ContentUri, null, null, null, querySorter);

            while(queryData.MoveToNext())
            {
                //---phone number---
                string callNumber = queryData.GetString(queryData.GetColumnIndex(CallLog.Calls.Number));

                //---date of call---
                string callDate =  queryData.GetString(queryData.GetColumnIndex(CallLog.Calls.Date));

                //---1-incoming; 2-outgoing; 3-missed---
                String callType = queryData.GetString(queryData.GetColumnIndex(CallLog.Calls.Type));
       }
        


} 

For Getting only Missed Call logs: 
public void  GetCallLogs(){

            // filter call logs by type = missed
            string queryFilter = String.Format ("{0}={1}", CallLog.Calls.Type, (int)CallType.Missed);

            // filter in desc order limit by 3
            // string querySorter = String.Format ("{0} desc limit 3", CallLog.Calls.Date);

            // filter in desc order limit by no
            string querySorter = String.Format ("{0} desc ", CallLog.Calls.Date);

            // CallLog.Calls.ContentUri is the path where data is saved
            Android.Database.ICursor queryData = ContentResolver.Query (CallLog.Calls.ContentUri, null, queryFilter, null, querySorter);

            while(queryData.MoveToNext())
            {
                //---phone number---
                string callNumber = queryData.GetString(queryData.GetColumnIndex(CallLog.Calls.Number));

                //---date of call---
                string callDate =  queryData.GetString(queryData.GetColumnIndex(CallLog.Calls.Date));

                //---1-incoming; 2-outgoing; 3-missed---
                String callType = queryData.GetString(queryData.GetColumnIndex(CallLog.Calls.Type));
            } 

For Getting only Incoming Call logs: 

string queryFilter = String.Format ("{0}={1}", CallLog.Calls.Type, (int)CallType.Incoming);


For Getting only outcoming Call logs: 

string queryFilter = String.Format ("{0}={1}", CallLog.Calls.Type, (int)CallType.Outgoing);


In the preceding code snippet, you check for missed calls that have not been acknowledged (i.e., that you have not called back) and print out their phone numbers.
In order to query the call_log content provider, you need to add the READ_CONTACTS permission to the AndroidManifest.xml file:

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