Accessing tabhost's JSONObject or JSONArray

Question

All I am trying to do is have a JSONObject that can be accessible from children tabs, so that I can put info into it.

 public class Example extends TabActivity{
            private JSONObject testtt = new JSONObject();
        public void writeJSON(String key, String value) throws JSONException {
         testtt.put(key, value);
         }
        public String getJSON(){
            return testtt.toString();
        }
     public void onCreate(Bundle savedInstanceState) {
                    super.onCreate(savedInstanceState);
            setContentView(R.layout.example);
                    //Creating the tabs and everything
                    //Is Here
     }
    }

I have next/prev buttons than navigate the tabs back and forth one of the tabs:

public void onClick(View v) {
 //Pre-alertDialog.setmessage stuff here.
   alertDialog.setMessage(Example.this.getJSON());
// Example.this gives this error: No enclosing instance of the type Example is accessible in scope
}

I have tried a ton of alternative stuff, and have gotten to the point of asking for help (extremely rare for me). Its also probably obvious that I am relatively new to android development.

EDIT: when attempting global variable via Class extends Application{ logcat edited

I figured my own problem out... I was adding an to the manifest... when all I needed to do was add the name to the EXISTING tag. — Luke3butler, Apr 19 '12 at 21:54

Easiest thing to do is use an Application object: stick the JSON on a shared variable in the Application object and access it from there in your other Activities.

I tried that... got a force close (I added it as an application to the manifest too) – Luke3butler Apr 19 '12 at 20:48
What's the crash error? Add the entire exception trace from logcat. – Femi Apr 19 '12 at 20:55
this might take a while... stupid me deleted all that code instead of commenting out. – Luke3butler Apr 19 '12 at 20:57
logcat screenshot... it breaks at this line of code: Jason jason = (Jason)getApplicationContext(); – Luke3butler Apr 19 '12 at 21:31
