I am trying to use:

B4X:
private static Map convertToMap(HashMap<?, ?> javaMap) {
     Map m = new Map();
     m.Initialize();
     for (Entry<?, ?> e : javaMap.entrySet()) {
       m.Put(e.getKey(), e.getValue());
     }
     return m;
   }

However I am getting

java:721: error: cannot find symbol
Map m = new Map();
^

What is the include that I need?

Already doing this:
import anywheresoftware.b4a.BA;
import anywheresoftware.b4a.*;

Where do you put this code?
Based on the sub signature he is using it inside inline java or java i guess
B4X:
private static Map convertToMap(HashMap<?, ?> javaMap) {
}

It will be easier to help if you provide more context. Where do you put this code?

Based on the error it treats the Map as java.util.Map.

thank you, Solved:

B4X:
import anywheresoftware.b4a.BA;
import anywheresoftware.b4a.*;
import anywheresoftware.b4a.objects.collections.*;

import android.app.Activity;
import android.content.Context;

import java.util.HashMap;
import java.util.List;

public static Map convertToMap(HashMap<String, String> javaMap) {
     Map m = new Map();
     m.Initialize();
     for (HashMap.Entry<String, String> e : javaMap.entrySet()) {
       m.Put(e.getKey(), e.getValue());
     }
     return m;
}
