How to get interesting data from Content Providers

We all know android has content provider, and we can access these data with content resolver,

1) add permission,

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

2) getContentResolver

        ContentResolver cr = getContentResolver();
        Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,

3) Enumerate and Query



For other data, for example, sms,etc,  it‘s similar, the only different is the uri, have fun!
