How to lookup for a string translation on android?

Question

I need to translate error codes that i receive from one of owner servers.

So, instead of having a string id i have a string, the error code, and i need to check the resources for possible translation.

How can i perform a lookup?

Turns out that there is a function for that, getIdentifier.

private String getStringResourceByName(Resources res, String aString) {
    String packageName =   App.getInstance().getPackageName();
    int resId =  App.getInstance().getResources().getIdentifier(aString, "string", packageName);
    return res.getString(resId);
}

Trying on a simple test:

@Test
public void test(){

    Resources res = serviceFactory.getApplicationContext().getResources();

    Log.d(TAG, "default language: "+ getStringResourceByName(res,"LG")); //will print the default definition.

    Configuration conf = res.getConfiguration();
    conf.locale = Locale.FRENCH; //for instance
    res.updateConfiguration(conf, null); //

    Log.d(TAG, "French: "+ getStringResourceByName( res,"LG"));//will print definition of LG in french resource file

}
