Call a function in every onFailure block in AndroidAsyncHTTP

Question

I'm using the android-async-http library in many locations in my app. My usual onFailure() block looks something like this:

APIClient.POST("/user/login", params, new JsonHttpResponseHandler() {
    public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
        // Do onSuccess stuff...
    }

    public void onFailure(int statusCode, Header[] headers, Throwable throwable, JSONObject error) {
        Toast.makeText(
            getApplicationContext(), 
            "Something Went Wrong!", 
            Toast.LENGTH_SHORT
        ).show();

        // Other onFailure stuff
    }
});

---

So I'm basically showing this Toast in every onFailure block. Isn't there a better way to do this? Can't I do something in the original APIClient.POST() method to do this for me every time? So, If I don't override the onFailure block for one call, it still shows this Toast. Here's my APIClient.POST method:

public static void POST(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
    // Maybe do somesthing with responseHandler here before passing it off to AsyncHttpClient?
    client.post(getAbsoluteUrl(url), params, responseHandler);
}

Appreciate any help I could get. Thanks!

You could do it like this, and use this class instead of the JsonHttpResponse:

public class MyJsonHttpResponseHandler extends JsonHttpResponseHandler {

    private Context context;

    public MyJsonHttpResponseHandler(Context context){
        super();
        this.context = context;
    }

    @Override
    public void onFailure(int statusCode, Header[] headers, Throwable throwable, JSONObject errorResponse) {
        Toast.makeText(
                context,
                "Something Went Wrong!",
                Toast.LENGTH_SHORT
        ).show();

    }
}

Use it like this

APIClient.POST("/user/login", params, new MyJsonHttpResponseHandler(getActivity()){ ....
