Android access to mobile phone records method _android

Android how to get phone records, this article for everyone to announce.

Get mobile phone call recording process:

1, to obtain contentresolver;

Contentresolver resolver = Getcontentresolver ();

2, Resolver.query (*);

URI:CallLog.Calls.CONTENT_URI that require incoming call records

3, the query to obtain the cursor data acquisition.

The main code is as follows:

Final Effect Diagram:

Attention:

Night God simulator does not seem to call the function, do not use the night God test this example
The moderator is using the Millet 4 true machine test, USB debugging process will crash directly, need to manually in the Security Center to give access to read call records. (depending on the personal machine situation, some machines may not need to be set manually)
