How to remove a contact programmatically in android

Question

I try the following code to remove contact with a specified number:

private void removeContact(Context context, String phone) {
    //context.getContentResol         


        

Answer 1

ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
        null, null, null, null);
while (cur.moveToNext()) {
    try{
        String lookupKey = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY));
        Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_LOOKUP_URI, lookupKey);
        System.out.println("The uri is " + uri.toString());
        cr.delete(uri, null, null);
    }
    catch(Exception e)
    {
        System.out.println(e.getStackTrace());
    }
}

I have used this code to delete contacts.It will delete sim contacts as well phone contacts or only contacts stored in phone storage.
