Check out googlei18n/libaddressinput: Google’s postal address library, powering Android and Chromium. There are two modules in the project :android and :common. You should only need :common to format the address for locale aware display.

import android.location.Address;
import android.support.annotation.NonNull;
import android.text.TextUtils;
import com.google.i18n.addressinput.common.AddressData;
import com.google.i18n.addressinput.common.FormOptions;
import com.google.i18n.addressinput.common.FormatInterpreter;
...
public static String getFormattedAddress(@NonNull final Address address, 
                                         @NonNull final String regionCode) {
    final FormatInterpreter formatInterpreter
            = new FormatInterpreter(new FormOptions().createSnapshot());
    final AddressData addressData = (new AddressData.Builder()
            .setAddress(address.getThoroughfare())
            .setLocality(address.getLocality())
            .setAdminArea(address.getAdminArea())
            .setPostalCode(address.getPostalCode())
            .setCountry(regionCode) // REQUIRED
            .build());
    // Fetch the address lines using getEnvelopeAddress,
    List<String> addressFragments = formatInterpreter.getEnvelopeAddress(addressData);
    // join them, and send them to the thread.
    return TextUtils.join(System.getProperty("line.separator"),
            addressFragments);
}

NOTE: regionCode must be a valid iso2 country code, because this is where the format interpreter pulls the address format from. (See RegionDataConstants for the list of formats, if you're curious.)

Sets the 2-letter CLDR region code of the address; see AddressData#getPostalCountry(). Unlike other values passed to the builder, the region code can never be null.

Example: US

801 CHESTNUT ST
ST. LOUIS, MO 63101

Example: JP
