Getting telephone US local area code with Android - telephonymanager

Question

I would like to know how can i get the device/user area code from within my android app
I know there is a lib named TelephonyManager but i couldn't find the country code feature
To make myself clear:
I have an activity which asks the user to enter his phone number and i want the area code to be taken from the device (from his carrier?)
If i would open my app in new york i would get +212 as the code and a text box to enter my own number

Answer 2

Sorry to revive a dead thread, but I spent a while trying to solve this issue so hopefully my response will help someone else.
The example in the original question is confusing, you say you want to append the country code, but give New York area code 212 as an example; That is not a country code it is a local area code. The country code for USA is 1. So you would want the final number to look like "1-212-xxx-xxxx". My answer below explains how to determine the country code, not the local area code.
To get the country calling code for your own number, use getSimCountryIso(). Do not use getNetworkCountryIso(); getNetworkCountryIso will return the country that you are currently located in, but if you are travelling this will return the wrong country. For example if you are from Albania but are travelling in New York getSimCountryIso will return "al", but getNetworkCountryIso will return "us". Obviously if you use the country code for the USA, you have the wrong number.
Now you have a two character country code; for example Canada will be "ca". You can then use this as a lookup key for the table below (obtained from http://www.sikosoft.com/item/international_telephone_country_codes_in_xml_format_using_iso_639-1).
Since country codes don't ever change, it is acceptable to hard code a lookup table in your application. Unfortunately there doesn't seem to be a direct way to get the user's current country code.

Answer 3

This question helped me so much, I want to give you all a class that provide country code from phone code and viceversa.
Usage:
CountryCodes.getCode(String country) returns international code from country sign
CountryCodes.getCountry(String code) returns country signs from international code
An instance of this class can be provided as adapter to Views, for example in Activity onCreate:
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_layout); // your layout xml
Spinner s = ( Spinner )findViewById( R.id.spinner1 ); // id of your spinner
CountryCodes cc = new CountryCodes( this );
s.setAdapter( cc );
TelephonyManager man = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
int index = CountryCodes.getIndex( man.getSimCountryIso() );
if( index > -1 )
{
s.setSelection( index );
}
}
What follows is the class code CountryCodes.java
import java.util.ArrayList;
import java.util.Locale;
import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;
/**
* Call getCountry( String code ) to get matching country sign.
* Call getCode( String country ) to get matching phone code.
* It has been extended from BaseAdapter in order to make it compatible with Spinner,
* ListView and so on (just instance it and give it as adapter).
*
* This class is provided AS IS without any warranty.
*

I'm using it and seems to work but, you know, just death and taxes are certain. Feel free to customize it and suggest fixes.

Answer 4

Use compile 'com.googlecode.libphonenumber:libphonenumber:8.0.1' dependency. This makes the task easy and provides accurate result because it's by google.
Here you can know more about it.
The output I m getting is something like this:
Here I m using spinner.
1) I have created a custom Adapter CountryCodesAdapter:
package com.amitupadhyay.getcountrycode;

public String regionCode;
public int countryCode;
public String regionName;
#Override
public int compareTo(String another) {
return regionCode != null && another != null ? regionCode.compareTo(another) : 1;
}
#Override
public boolean equals(Object o) {
if (this == o)
return true;
if (o != null && o instanceof CountryCode) {
CountryCode other = (CountryCode) o;
return regionCode != null &&
regionCode.equals(other.regionCode);
}
return false;
}
#Override
public String toString() {
return regionCode;
}
}
public CountryCodesAdapter(Context context, int viewId, int dropdownViewId) {
this(context, new ArrayList<CountryCode>(), viewId, dropdownViewId);

mData.add(cc);
}
public void clear() {
mData.clear();
}
public void sort(Comparator<? super CountryCode> comparator) {
Collections.sort(mData, comparator);
}
#Override

else {

return (regionCode == null || regionCode.equals("ZZ") ||
regionCode.equals(PhoneNumberUtil.REGION_CODE_FOR_NON_GEO_ENTITY))
? "" : new Locale("", regionCode).getDisplayCountry(language);
}
}
2) Now the layout of my Activity where I am displaying the spinner of country code is:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:orientation="vertical">
<include layout="#layout/toolbar_simple"/>
<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scrollbars="vertical" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:orientation="vertical"
android:padding="18dip" >
<Spinner android:id="#+id/phone_cc"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:spinnerMode="dialog"/>
<EditText
android:id="#+id/phone_number"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="#string/hint_validation_number"
android:inputType="phone" />
<Button
android:id="#+id/button_validate"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:text="#string/button_validate" />
</LinearLayout>
</ScrollView>
</LinearLayout>
3) java Activity code is below:

Few extra features:
a) Your country will get automatically selected in the spinner.
To achieve I have used this:
Phonenumber.PhoneNumber myNum = getMyNumber(this);
if (myNum != null) {
CountryCode cc = new CountryCode();
cc.regionCode = util.getRegionCodeForNumber(myNum);
if (cc.regionCode == null)
cc.regionCode = util.getRegionCodeForCountryCode(myNum.getCountryCode());
mCountryCode.setSelection(ccList.getPositionForId(cc));
mPhone.setText(String.valueOf(myNum.getNationalNumber()));
}
else {
final TelephonyManager tm = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
final String regionCode = tm.getSimCountryIso().toUpperCase(Locale.US);
CountryCode cc = new CountryCode();
cc.regionCode = regionCode;
cc.countryCode = util.getCountryCodeForRegion(regionCode);
mCountryCode.setSelection(ccList.getPositionForId(cc));
}
I think this method is little better than other ways listed here. So I posted this. Hope someone may find it helpful :-)

Answer 5

in this case this would look like:
/**
* network iso code: referred and listed at:
* http://en.wikipedia.org/wiki/List_of_mobile_country_codes
*/
TelephonyManager manager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
Constants.DEVICE_COUNTRY = manager.getNetworkCountryIso();
So nobody has to look and double-check (context is a local variable of a valid Context object).
Constants.DEVICE_COUNTRY is of Type String :) (just a variable)

add these to the string.xml
Enjoy:)

Answer 7

If you happen to use Google's libphonenumber anyway, and if you work with phone numbers, it's rather likely you do, you can use its internal data that describes the same. It's not public, so you have to use reflection to reach it:
Map<Integer, List<String>> CountryCodeToRegionCodeMap_getCountryCodeToRegionCodeMap() {
try {
Method method = CountryCodeToRegionCodeMap.class.getDeclaredMethod("getCountryCodeToRegionCodeMap");
method.setAccessible(true);
return (Map<Integer, List<String>>) method.invoke(null);
}
catch (Exception e) {
Log.e(..., e.toString());
return null;
}
}
Then you can search or process that map to get the data you want.

Answer 8

I know it way too late. But I have a batter solution of it. Since doing it with the list of String and looping through it might slow it down. Using Hashmap would be a batter solution for it.
I wrote a PhoneUtil class for it. Here is code ( i only have 20 or so countries but you can add more to it )
import android.content.Context;
import android.telephony.TelephonyManager;
import java.util.HashMap;
/**
* Created by Dell on 1/19/2017.
*/
public class PhoneUtil {
public static String getCountryCode(Context context) {
TelephonyManager manager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
if (manager != null) {
return getCountryCodeFromMap(manager.getSimCountryIso().toUpperCase());
} else {
return null;
}
}
private static String getCountryCodeFromMap(String countryCode) {
HashMap<String, String> countryCodeMap = new HashMap<>();
countryCodeMap.put("TJ", "+992");
countryCodeMap.put("TZ", "+255");
countryCodeMap.put("TH", "+66");
countryCodeMap.put("TG", "+228");
countryCodeMap.put("TK", "+690");
countryCodeMap.put("TO", "+676");
countryCodeMap.put("TN", "+216");
countryCodeMap.put("TR", "+90");
countryCodeMap.put("TM", "+993");
countryCodeMap.put("TV", "+688");
countryCodeMap.put("AE", "+971");
countryCodeMap.put("UG", "+256");
countryCodeMap.put("GB", "+44");
countryCodeMap.put("UA", "+380");
countryCodeMap.put("UY", "+598");
countryCodeMap.put("US", "+1");
countryCodeMap.put("UZ", "+998");
countryCodeMap.put("VU", "+678");
countryCodeMap.put("VA", "+39");
countryCodeMap.put("VE", "+58");
countryCodeMap.put("VN", "+84");
countryCodeMap.put("WF", "+681");
countryCodeMap.put("YE", "+967");
countryCodeMap.put("ZM", "+260");
countryCodeMap.put("ZW", "+263");
countryCodeMap.put( "MY","+60");
countryCodeMap.put("PK","+92");
return countryCodeMap.get(countryCode);
}
}

Answer 9

In class TelephonyManager, I find a method public String getNetworkCountryIso (), this may be what you want. Also, there are some other method which can return more info about the phone. You may read http://en.wikipedia.org/wiki/List_of_mobile_country_codes to see which country is represented by a MCC.

Answer 10

This is code to put in your Main Activity to replace the code that Wais posted near the top of this page. Take the array that Wais posted and add that to your app in the resources. I might have slightly changed the name of the array to be stored in resources, other than that, this code should work well and be easier to read if you are learning:
public String getCountryCode()
{
String my_country_code_letters = getMyLocale().getCountry();
String[] country_codes = this.getResources().getStringArray(R.array.country_codes);
String my_country_code_number = null;
//------------------------------------------------------------------------------------------
for (int i=0; i < country_codes.length && i != (-1); i++)
{
/**split_code:
* 1) split_code[0] == numbers
* 2) split_code[1] == letters**/
String[] split_code = country_codes[i].split(",");
//--------------------------------------------------------------------------------------
if (split_code[1].matches(my_country_code_letters))
{
my_country_code_number = split_code[0];
break;
}
//--------------------------------------------------------------------------------------
}
//------------------------------------------------------------------------------------------
return my_country_code_number;
}
public Locale getMyLocale()
{
Log.i(TAG, "Running getMyLocale()");
Locale myLocale = "";
//------------------------------------------------------------------------------------------
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N)
{
myLocale = getBaseContext().getResources().getConfiguration().getLocales().get(0);
}
else
{
//noinspection deprecation
myLocale = getBaseContext().getResources().getConfiguration().locale;
}
//------------------------------------------------------------------------------------------
return myLocale;
}
