Android: how to access the SIM contact table using the SDK?

Question

I am trying to use this query to read the contacts on the SIM.

            cur = managedQuery(Uri.parse("content://icc/adn")
                ,null
                ,null
                ,null
                ,null
                );

The application has READ_CONTACTS and WRITE_CONTACTS permissions. Yet, the query returns an exception.

What's wrong?

Alidus

content://icc/adn is not part of the Android SDK. – Penutian

Then, again, what is part of the Android SDK and gives access to the SIM contacts? The code was inspired by groups.google.com/group/android-developers/browse_thread/thread/… : the author uses content://icc/adn and claims he can read contacts (and insert, but not delete them). Also, replacing content://icc/adn with gibberish like content://icc/asdasd causes a different exception, something like "URI unknown": it means that content://icc/adn has some meaning. – Alidus

The same works on the Android emulator, not on a real phone. The URIs content://icc/fdn and content://icc/sdn work on both emulator and phone – Alidus

Just have a look at this link #15563290 This code works good – Shad

In IccProvider -> ADN (Abbreviated dialing number), FDN (Fixed dialer number), SDN (Service dialing number) – Clive

Answer 1

i have used the following code to get the simcard details..It works fine

Uri simUri = Uri.parse("content://icc/adn");
        Cursor cursorSim    = this.getContentResolver().query(simUri, null, null,null, null);

         while (cursorSim.moveToNext()) {           
             listName.          add(cursorSim.getString(cursorSim.getColumnIndex("name")));
             listContactId.     add(cursorSim.getString(cursorSim.getColumnIndex("_id")));      
             listMobileNo.      add(cursorSim.getString(cursorSim.getColumnIndex("number")));
            }

Here the name, _id, number are column names from the simcard table

are you sure that the content URI will stay the same in future releases? – Healthy

Answer 2

i got it,

String simUrl = "content://icc/adn";
Intent intent = new Intent();
            Log.d(TAG, "simUrl=" + simUrl);
            intent.setData(Uri.parse(simUrl));
            Uri uri = intent.getData();
            Cursor mCursor = context.getContentResolver().query(uri, null,
                    null, null, null);

and then, for(...){...}, you know

Unscrew

Cursor mCursor = context.getContentResolver().query(uri, null, null, null, null); causes the same exception in this case as well... – Alidus

OK, it maybe the environment problems, you have to get the sim card state in ("no known" || "ready"). before you run this, please restart your device. – Unscrew

I just implemented a small piece of code that used to display a list of contacts in SIM card. Hope that it can help you

private void displaySIMContacts() {
    try {
        String simPhoneId = null;
        String simPhoneNum = null;
        String simPhoneName = null;

        Uri simUri = Uri.parse("content://icc/adn");
        Cursor simCursor = getContentResolver().query(simUri, null, null, null, null);

        while(simCursor.moveToNext()) {
            simPhoneId = simCursor.getString(simCursor.getColumnIndex("_id"));
            simPhoneNum = simCursor.getString(simCursor.getColumnIndex("name"));
            simPhoneName = simCursor.getString(simCursor.getColumnIndex("number"));
            Log.v("!!!", " id = " + simPhoneId + " - name = " + simPhoneName
                + " - number = " +simPhoneNum);
        }
    }
    catch (Exception e) {
       e.printStackTrace();
    }
}
