echomtg_method_example.java

// auth example, would be inside an activity or fragment class method
SharedPreferences sharedPref;
sharedPref = getActivity().getPreferences(Context.MODE_PRIVATE);
String email = "your@email.com";
String pass = "asdfsbfsbsadfsa";
EchoMTGJavaAPIWrapper.getInstance(getActivity().getApplicationContext()).authRequest(new EchoMTGJavaAPIWrapper.EchoCallback(){
          @Override
          public void onSuccess(String result){
              JSONObject jsonObject= null;
              String token = null;
              try {

                  jsonObject = new JSONObject(result);
                  token = jsonObject.getString("token");

              } catch (JSONException e) {
                  e.printStackTrace();
              }


              Toast.makeText(getActivity().getApplicationContext(), "Successful Login", Toast.LENGTH_SHORT).show();

              SharedPreferences.Editor editor = sharedPref.edit();
              editor.putString(getString(R.string.token_reference), token);
              editor.commit();
          }
      },email,pass);
