The process of obtaining mobile phone call records:
1. Get ContentResolver;
ContentResolver resolver = getContentResolver();
2、resolver.query(*);
URI for incoming call logs: CallLog.Calls.CONTENT_URI ("content://call_log/calls")
3. Obtain data from the Cursor obtained by the query.
The source code of the content provider responsible for storing call records is under the ContactsProvider project:
Source path: com/ Android /providers/contacts/ CallLogProvider.Java
The database used is: /data/data/com.android.providers.contacts/databases/contacts2.db
Table name: calls
View phone records:
CallLog.Calls.CONTENT_URI : Equivalent to: Uri.parse("content://call_log/calls");
Contact name for CallLog.Calls.CACHED_NAME query
CallLog.Calls.NUMBER phone number
CallLog.Calls.TYPE Phone Type
There are three types of call records: (Incoming calls: 1, Outgoing calls: 2, Missing calls: 3)
Incoming calls: CallLog.Calls.INCOMING_TYPE (constant value: 1)
Dialed: CallLog.Calls.OUTGOING_TYPE (constant value: 2)
Missed: CallLog.Calls.MISSED_TYPE (constant value: 3)
Date of the call (the millisecond value to be processed when the CallLog.Calls.DATE date is returned)
SimpleDateFormat simple = new SimpleDateFormat("yyyy-MM-dd "+"hh:mm:ss");
Date dates = new Date(Long.parseLong(date));
String time=simple.format(dates);
Query all records
ContentResolver resolver = getContentResolver();
resolver.query(CallLog.Calls.CONTENT_URI, null, null, null, null);
Query all records of a contact (by phone number)
resolver.query(CallLog.Calls.CONTENT_URI, null, "number=?", new String[]{"15101689022"}, null);
Query all missed call records of a contact (by phone number)
resolver.query(CallLog.Calls.CONTENT_URI, null, "number=? and type=3", new String[]{"15101689022"}, null);

Final renderings:
Notice:
The night god simulator does not seem to have the function of making calls. Do not use the night god test. In this example, the
moderator uses the Xiaomi Mi 4 real machine test. During the usb debugging process, it will crash directly. You need to manually assign the app to read the call record in the security center. permissions. (Depending on your personal machine, some machines may not require manual settings)
