I want to get the field name of class in android

I want to get the field name of class in android. for this I am using this code

public static String checkForNull(Object obj) {
    Class cls = obj.getClass();
    Field fields[] = cls.getDeclaredFields();
    for (Field field : fields) {
        Object object = null;
        try {
            object = field.get(obj);
        } catch (IllegalAccessException e) {
            return "The field " + field.getName() + " of " + cls.getSimpleName() + " is not accessible!";
        }
        if (object == null) {
            return "The field " + field.getName() + " of " + cls.getSimpleName() + " is null!";
        } else if (object instanceof String) {
            String string = (String) object;
            if (string.equals("")) {
                return "The field " + field.getName() + " of " + cls.getSimpleName() + " is empty!";
            }
        }
    }
    return null;
}

but this code return generic name of class field like a,b,c...etc. This code work fine in netbeans.

Looks like obfuscated names, most probably you have default settings for ProGuard and Android SDK performs some code obfuscation, see https://developer.android.com/studio/build/shrink-code.html

If you would like to see original field names, you should disable obfuscation either completely or for this particular class / package.
