Quick Overview
Android Async HTTP is a popular asynchronous HTTP client library for Android. It provides a simple and efficient way to make HTTP requests in Android applications, handling threading and response parsing automatically.
Pros
- Easy to use with a simple and intuitive API
- Supports both synchronous and asynchronous requests
- Handles threading automatically, improving app performance
- Integrates well with Android's AsyncTask for background operations
Cons
- No longer actively maintained (last update in 2016)
- Lacks support for modern Android features and best practices
- May have security vulnerabilities due to lack of updates
- Limited compared to more modern networking libraries like Retrofit or OkHttp
Code Examples
- Making a GET request:
AsyncHttpClient client = new AsyncHttpClient();
client.get("https://api.example.com/data", new AsyncHttpResponseHandler() {
@Override
public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
// Handle successful response
}
@Override
public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
// Handle error
}
});
- Making a POST request with parameters:
RequestParams params = new RequestParams();
params.put("key", "value");
AsyncHttpClient client = new AsyncHttpClient();
client.post("https://api.example.com/submit", params, new JsonHttpResponseHandler() {
@Override
public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
// Handle JSON response
}
@Override
public void onFailure(int statusCode, Header[] headers, Throwable throwable, JSONObject errorResponse) {
// Handle error
}
});
- Setting request headers:
AsyncHttpClient client = new AsyncHttpClient();
client.addHeader("Authorization", "Bearer token123");
client.get("https://api.example.com/protected", new AsyncHttpResponseHandler() {
// Handle response
});
Getting Started
- Add the dependency to your
build.gradle
file:
dependencies {
implementation 'com.loopj.android:android-async-http:1.4.9'
}
- Add Internet permission to your
AndroidManifest.xml
:
<uses-permission android:name="android.permission.INTERNET" />
- Create an instance of AsyncHttpClient and make requests:
AsyncHttpClient client = new AsyncHttpClient();
client.get("https://api.example.com/data", new AsyncHttpResponseHandler() {
@Override
public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
String response = new String(responseBody);
// Process the response
}
@Override
public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
// Handle error
}
});

Code Comparison
Both repositories contain the same codebase, as they are mirrors of the same project. Here's a sample of how to make a GET request using android-async-http:
AsyncHttpClient client = new AsyncHttpClient();
client.get("https://api.example.com/data", new AsyncHttpResponseHandler() {
@Override
public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
// Handle successful response
}
@Override
public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
// Handle error
}
});
Since both repositories contain the same code, there are no differences to highlight in the code comparison.
It's worth noting that the android-async-http project has been largely superseded by more modern HTTP libraries for Android, such as OkHttp or Retrofit. These newer libraries offer more features, better performance, and ongoing maintenance.
Square’s meticulous HTTP client for the JVM, Android, and GraalVM.
Pros of OkHttp
- More actively maintained and updated
- Better performance and efficiency, especially for SPDY and HTTP/2
- Robust features like connection pooling, transparent GZIP, and caching
Cons of OkHttp
- Steeper learning curve for beginners
- Requires more setup and configuration for basic use cases
- Larger library size compared to Android Async HTTP
Code Comparison
android-async-http:
AsyncHttpClient client = new AsyncHttpClient();
client.get("https://api.example.com", new AsyncHttpResponseHandler() {
@Override
public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
// Handle success
}
});
OkHttp:
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder()
.url("https://api.example.com")
.build();
client.newCall(request).enqueue(new Callback() {
@Override
public void onResponse(Call call, Response response) throws IOException {
// Handle response
}
});
Both libraries offer asynchronous HTTP requests, but OkHttp provides more flexibility and control over the request and response handling. Android Async HTTP has a simpler API for basic use cases, while OkHttp offers more advanced features and customization options. OkHttp is generally considered more modern and efficient, especially for complex networking scenarios.
A type-safe HTTP client for Android and the JVM
Pros of Retrofit
- Type-safe API for HTTP requests, reducing runtime errors
- Annotation-based approach for defining API endpoints
- Seamless integration with popular libraries like OkHttp and RxJava
Cons of Retrofit
- Steeper learning curve due to its more complex architecture
- Requires more setup and configuration compared to android-async-http
Code Comparison
Retrofit:
public interface GitHubService {
@GET("users/{user}/repos")
Call<List<Repo>> listRepos(@Path("user") String user);
}
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("https://api.github.com/")
.build();
GitHubService service = retrofit.create(GitHubService.class);
Call<List<Repo>> repos = service.listRepos("octocat");
android-async-http:
AsyncHttpClient client = new AsyncHttpClient();
client.get("https://api.github.com/users/octocat/repos", new JsonHttpResponseHandler() {
@Override
public void onSuccess(int statusCode, Header[] headers, JSONArray response) {
// Handle JSON response
}
});
Retrofit offers a more structured and type-safe approach to API calls, while android-async-http provides a simpler, callback-based method. Retrofit's annotation-based system allows for cleaner code organization, but requires more initial setup. android-async-http is easier to get started with but may be more prone to runtime errors due to its lack of compile-time checks.
Pros of Volley
- Better performance through intelligent request dispatching and caching
- Easier request prioritization and cancellation
- Built-in support for request queueing and retry policies
Cons of Volley
- Steeper learning curve due to more complex API
- Less flexibility for custom implementations
- Larger library size, which may impact app size
Code Comparison
android-async-http:
AsyncHttpClient client = new AsyncHttpClient();
client.get("https://api.example.com", new AsyncHttpResponseHandler() {
@Override
public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
// Handle success
}
});
Volley:
RequestQueue queue = Volley.newRequestQueue(this);
StringRequest stringRequest = new StringRequest(Request.Method.GET, "https://api.example.com",
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
// Handle success
}
}, new Response.ErrorListener() { /* ... */ });
queue.add(stringRequest);
Both libraries offer asynchronous HTTP requests for Android, but Volley provides more advanced features like request prioritization and caching. android-async-http has a simpler API, making it easier to use for basic tasks. Volley is generally preferred for more complex applications with higher performance requirements, while android-async-http may be suitable for simpler projects or those requiring quick implementation.

@Override
public void onResponse(JSONObject response) {
// Handle response
}
});
android-async-http:
AsyncHttpClient client = new AsyncHttpClient();
client.get("https://api.example.com/data?key=value", new JsonHttpResponseHandler() {
@Override
public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
// Handle response
}
});
Both libraries offer similar functionality for making HTTP requests, but Fast-Android-Networking provides a more fluent API with method chaining. It also includes built-in support for various response types, while android-async-http requires separate response handlers for different data formats.
Fast-Android-Networking offers more modern features and better performance, but android-async-http may be preferred for simpler projects or by developers already familiar with its API.
