what i am doing wrong ?

Try with

SharedPreferences.Editor editor = sharedPrefs.edit();

or adding

import android.content.SharedPreferences.Editor;

(Untested, but I guess that at least one should work)

i have tried

#If Java
import android.content.Context;
import android.content.SharedPreferences.*;


private static String uniqueID = null;
private static final String PREF_UNIQUE_ID = "PREF_UNIQUE_ID";

public synchronized static String id(Context context) {
   if (uniqueID == null) {
      SharedPreferences sharedPrefs = context.getSharedPreferences(
         PREF_UNIQUE_ID, Context.MODE_PRIVATE);
      uniqueID = sharedPrefs.getString(PREF_UNIQUE_ID, null);
      if (uniqueID == null) {
         uniqueID = UUID.randomUUID().toString();
         Editor editor = sharedPrefs.edit();
         editor.putString(PREF_UNIQUE_ID, uniqueID);
         editor.commit();
      }
   }
    return uniqueID;
}


#End If

when i run

jo.RunMethod("id", Null)

i got runtime exception

java.lang.RuntimeException: Method: id not matched.
at anywheresoftware.b4j.object.JavaObject.RunMethod(JavaObject.java:130)

 

[JordiCP]

The method expects one parameter (context)

 

[Addo]

I am not sure what to pass in b4a

 

[JordiCP]

Try with

...
Dim JContext as JavaObject
JCOntext.initializeContext
JO.RunMethod("id", Array(JContext))
...
