Try this:

 private class FetchData extends AsyncTask<Context, Void, Void> {
     protected Long doInBackground(Context... c) {
         Context myContext = c[0];
// Do your things here....
     }


     protected void onPostExecute() {
// Insert your post execute code here
     }
 }

You can call this AsyncTask by the following line - assuming you are in an activity:

 new FetchData().execute(this);

if You cannot change your AsyncTask deceleration, then you can try using a static variable - although it is not as efficient and pretty as AsyncTask deceleration. Try this:

Class myStatic{
private  static Context mContext;


static public void setContext(Context c);
mContext = c;
}

static public Context getContext(){
return mContext;
}

}

and in your main code, before you call AsyncTask, call this:

myStatic.setContext(this);

in your doInBackground method of your AsyncTask, add this:

Context myContext = myStatic.getContext();
