Android Asynchronous Http Client

Motivation

In Android it is highly inadvisable to do heavy lifting in the UI thread. When you even try to do some networking stuff like fetching images from a web server you might get an

android.os.NetworkOnMainThreadException

I’ve also written about it here

To work around this issue you can use a third party library like android-async-http.

Gradle Dependency

dependencies {
    ...
    implementation 'com.loopj.android:android-async-http:1.4.9'
}

AsyncClient

AsyncHttpClient client = new AsyncHttpClient();

client.get(URL, params, new JsonHttpResponseHandler(){
    @Override
    public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
        super.onSuccess(statusCode, headers, response);
    }
});

Build Request Params

RequestParams params = new RequestParams();
params.put("lat", latitude);
params.put("lon", longitude);
params.put("appid", APP_ID);
