How to get ISO Country code in android applications?

Question

I am a new developer on android application. I would like to get the ISO Country code when I pass the mobile number with country code. If I pass the mobile number as 1-319-491-6338, can I get country ISO code as US / USA in android?

I have written the code as follows:

      TelephonyManager tm = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
      String countryCode = tm.getSimCountryIso();
      String mobileno="1-319-491-6338";

Here, where can I pass the mobile number?

Can anybody please help me ?

Thanks in advance

You may not be able to query the country code programmatically via the standard API but you could include a table in your app. Such a table is easily found via Google (e.g. http://countrycode.org/).

Danger Will Robinson!: However, one should ask yourself what question you are trying to answer. Implicit in your question is that assumption that there is a one-to-one mapping between international dialling codes and ISO country codes. This is not true. For example, both the USA and Canada have the international dialling code '1'.

Perhaps think about re-structuring your app's interface. Allow the user to select a country to associate with the phone number but use the table from http://countrycode.org/ to order the most likely candidates at the top?
