Reflection in Android?

Question

I'm little bit stuck on my current Android app project, the thing is that i have 84 variable on my AppPreference Class, now I'm required to get all those variables at one, to create packages and send the over bluetooth, i was thinking that maybe Reflections would help me do it, here is what I'm trying to do:

1.- Build a String out of my i and j variables:

for(int i=1;i <= 7;i++){
            for(int j = 1;j <=4;j++){

                String func ="getD"+i+"t"+j+"h";

  }
}

2.- My functions are the following:

    public class AppPreferences {

    public static final String NOZZ = "nozzles";
    public static final String TANK = "tank";
    public static final String SYNC ="sync";

3.- The instance of the class is called _appPreferences:

_appPrefs = new AppPreferences(getContext().getApplicationContext());

4.-I would like to do something like this:

public void syncData(){

        for(int i=1;i <= 7;i++){
            for(int j = 1;j <=4;j++){

                String func ="getD"+i+"t"+j+"h";
                String temp = _appPrefs.func;
            }
        }
    }

Is this even possible? I think its called Reflections, but i can find a good example since I'm new with reflections. Sorry for my English I'm not native english speaker. Thanks in advance.

Is that approach required ? Why you do not use map or list and add proper logic which will simplify things you want to do. — Rafal, Mar 06 '17 at 22:13
something like that http://stackoverflow.com/a/4896334/814304 ? — iMysak, Mar 06 '17 at 22:18
how would i populate the hashmap? it would require something like this too? the things is that all those values need to be saved for the user every time they open the app, the app is all about configuring an schedule to run on an Arduino. — Iñaki Pedroche Aramburu, Mar 06 '17 at 22:23
@iMysak already look into that, but is not too clear for me, as i said it before I'm not familiar with what they are proposing there. — Iñaki Pedroche Aramburu, Mar 06 '17 at 22:24
When I see something this tortured, I realize it must be getting done with the wrong tool. I think what you want in this case is a database. — Dale, Oct 18 '20 at 21:30

Lets assume you have:

  class AppPreferences {
    public void d2t3h() {
      System.out.println("helo");
    }
  }

Then try next code(working example, I used static nested class AppPreferences):

public static void main(String[] args) {
  AppPreferences preferences = new AppPreferences();
  for(int i=1;i <= 7;i++){
    for(int j = 1;j <=4;j++){
      try {
        String func ="getD"+i+"t"+j+"h";
        Method method = AppPreferences.class.getMethod(func);
        Object result = method.invoke(preferences);
        System.out.print(result);
      } catch (Exception e) {
        System.err.print(".");
      }
    }
}

I guess now you figure out how to use it next, If you want I can add more explanation here.

I you need to invoke method with parameters then you need to define them:

    Method method = AppPreferences.class.getMethod(func, String.class);
    Object result = method.invoke(a, "param");

what does "a" stands for in the method.invoke(a)? I'm really new with Reflections :C – Iñaki Pedroche Aramburu Mar 06 '17 at 22:43
