    Create a global variable like:

    Context mContext;
    

    Then add a constructor to your class, in which you accept a Context parameter and assign it to mContext like:

    public AgAppHelperMethods(Context context) {
          mContext = context;
    }
    

    Create an object in your Activity like:

    AgAppHelperMethods helper = new AgAppHelperMethods(getBaseContext());
    

    Finally, to show your Toast use:

     Toast.makeText(mContext, "error  server not responding " + e.getMessage(), Toast.LENGTH_LONG).show();
