how to return arabic translations to resource id?

I'm working on an app that contain sqlite database, the concept of the app is to enter and save data that translation part is the problem has two languages Arabic and English when the user insert new product he has to select the item type from spinner (which is translated to Arabic )when the user changes the device language the saved data (item type is not being translated) I've tried two methods to solve this but they are not working with Arabic language

The first method is returning wrong translated value (its return another arabic word not the the expected word ):

 public int getStringResourceByName(Context context, String name) {
    int id = 0;
    Field[] fields = R.string.class.getFields();
    for (Field field : fields) {

        try { //field.getName();
            id = field.getInt(name);

            return id;
        } catch (Exception ex) {
            break;
        }
    }

    return id;

}

The adapter code

textViewquantity.setText(context.getString(R.string.last_added_qty)+" " + repo.getQuantity() + " "+context.getResources().getString(mdatabase.getStringResourceByName (context, repo.getItemsType())));

the second method is working fine with English data but when I insert data in Arabic language the app crashes

The second method code

public static int getResId(String resName, Class<?> c) {

    try {
        Field idField = c.getDeclaredField(resName);
        return idField.getInt(idField);
    } catch (Exception e) {
        e.printStackTrace();
        return -1;
    }
}

the code in the adapter

 textViewquantity.setText(context.getString(R.string.last_added_qty)+" " + repo.getQuantity() + " " + context.getResources().getString(mdatabase.getResId(repo.getItemsType(),R.string.class)));

and it's giving me this result with Arabic language android.content.res.Resources$NotFoundException: String resource ID #0xffffffff

where did I go wrong with these methods, please help i've tried everything any suggestion !?
