About Fast Android Networking Library
Fast Android Networking Library is a powerful library for doing any type of networking in Android applications which is made on top of OkHttp Networking Layer.
Fast Android Networking Library takes care of each and everything. So you don't have to do anything, just make request and listen for the response.
Why use Fast Android Networking ?
- Recent removal of HttpClient in Android Marshmallow(Android M) made other networking libraries obsolete.
- No other single library does each and everything like making request, downloading any type of file, uploading file, loading image from network in ImageView, etc. There are some libraries but they are outdated.
- No other library provides simple interface for doing all types of things in networking like setting priority, cancelling, etc.
- As it uses Okio , No more GC overhead in android applications. Okio is made to handle GC overhead while allocating memory. Okio does some clever things to save CPU and memory.
- It uses OkHttp , more importantly it supports HTTP/2.

Requirements
Fast Android Networking Library can be included in any Android application.
Fast Android Networking Library supports Android 2.3 (Gingerbread) and later.
Using Fast Android Networking Library in your application
Add this in your settings.gradle:
maven { url 'https://jitpack.io' }
If you are using settings.gradle.kts, add the following:
maven { setUrl("https://jitpack.io") }
Add this in your build.gradle
implementation 'com.github.amitshekhariitbhu.Fast-Android-Networking:android-networking:1.0.4'
If you are using build.gradle.kts, add the following:
implementation("com.github.amitshekhariitbhu.Fast-Android-Networking:android-networking:1.0.4")
Do not forget to add internet permission in manifest if already not present
<uses-permission android:name="android.permission.INTERNET" />
Then initialize it in onCreate() Method of application class :
AndroidNetworking.initialize(getApplicationContext());
Initializing it with some customization , as it uses OkHttp as networking layer, you can pass custom okHttpClient while initializing it.
// Adding an Network Interceptor for Debugging purpose :
OkHttpClient okHttpClient = new OkHttpClient() .newBuilder()
.addNetworkInterceptor(new StethoInterceptor())
.build();
AndroidNetworking.initialize(getApplicationContext(),okHttpClient);
Using the Fast Android Networking with Jackson Parser
Add this in your build.gradle
implementation 'com.github.amitshekhariitbhu.Fast-Android-Networking:jackson-android-networking:1.0.4'
If you are using build.gradle.kts, add the following:
implementation("com.github.amitshekhariitbhu.Fast-Android-Networking:jackson-android-networking:1.0.4")
// Then set the JacksonParserFactory like below
AndroidNetworking.setParserFactory(new JacksonParserFactory());
Using the Fast Android Networking with RxJava2
Add this in your build.gradle
implementation 'com.github.amitshekhariitbhu.Fast-Android-Networking:rx2-android-networking:1.0.4'
If you are using build.gradle.kts, add the following:
implementation("com.github.amitshekhariitbhu.Fast-Android-Networking:rx2-android-networking:1.0.4")
Using the Fast Android Networking with RxJava
Add this in your build.gradle
implementation 'com.github.amitshekhariitbhu.Fast-Android-Networking:rx-android-networking:1.0.4'
If you are using build.gradle.kts, add the following:
implementation("com.github.amitshekhariitbhu.Fast-Android-Networking:rx-android-networking:1.0.4")

}
@Override
public void onError(ANError error) {
// handle error
}
});
JSONObject jsonObject = new JSONObject();
try {
jsonObject.put("firstname", "Amit");
jsonObject.put("lastname", "Shekhar");
} catch (JSONException e) {
e.printStackTrace();
}
AndroidNetworking.post("https://fierce-cove-29863.herokuapp.com/createUser")
.addJSONObjectBody(jsonObject) // posting json
.setTag("test")
.setPriority(Priority.MEDIUM)
.build()

AndroidNetworking.forceCancel("tag"); // All the requests with the given tag will be cancelled , even if any percent threshold is
// set , it will be cancelled forcefully.
AndroidNetworking.cancelAll(); // All the requests will be cancelled.
AndroidNetworking.forceCancelAll(); // All the requests will be cancelled , even if any percent threshold is
// set , it will be cancelled forcefully.
Loading image from network into ImageView

// do anything with bitmap
}
@Override
public void onError(ANError error) {
// handle error
}
});
Error Code Handling
public void onError(ANError error) {
if (error.getErrorCode() != 0) {
// received error from server
// error.getErrorCode() - the error code from server
// error.getErrorBody() - the error body from server
// error.getErrorDetail() - just an error detail
Log.d(TAG, "onError errorCode : " + error.getErrorCode());
Log.d(TAG, "onError errorBody : " + error.getErrorBody());
Log.d(TAG, "onError errorDetail : " + error.getErrorDetail());
// get parsed error object (If ApiError is your class)
ApiError apiError = error.getErrorAsObject(ApiError.class);
} else {
// error.getErrorDetail() : connectionError, parseError, requestCancelledError
Log.d(TAG, "onError errorDetail : " + error.getErrorDetail());
}
}
Remove Bitmap from cache or clear cache
AndroidNetworking.evictBitmap(key); // remove a bitmap with key from LruCache
AndroidNetworking.evictAllBitmap(); // clear LruCache
Prefetch a request (so that it can return from cache when required at instant)
AndroidNetworking.get("https://fierce-cove-29863.herokuapp.com/getAllUsers/{pageNumber}")
.addPathParameter("pageNumber", "0")
.addQueryParameter("limit", "30")
.setTag(this)
.setPriority(Priority.LOW)
.build()
.prefetch();
Customizing OkHttpClient for a particular request
OkHttpClient okHttpClient = new OkHttpClient().newBuilder()
.addInterceptor(new GzipRequestInterceptor())
.build();
AndroidNetworking.get("https://fierce-cove-29863.herokuapp.com/getAllUsers/{pageNumber}")
.addPathParameter("pageNumber", "0")
.addQueryParameter("limit", "3")
.addHeaders("token", "1234")
.setTag("test")
.setPriority(Priority.LOW)
.setOkHttpClient(okHttpClient) // passing a custom okHttpClient
.build()
.getAsJSONArray(new JSONArrayRequestListener() {
@Override
public void onResponse(JSONArray response) {
// do anything with response
}
@Override
public void onError(ANError error) {
// handle error
}
});
Making a conditional request (Building a request)
ANRequest.GetRequestBuilder getRequestBuilder = new ANRequest.GetRequestBuilder(ApiEndPoint.BASE_URL + ApiEndPoint.CHECK_FOR_HEADER);
if(isHeaderRequired){
getRequestBuilder.addHeaders("token", "1234");
}
if(executorRequired){
getRequestBuilder.setExecutor(Executors.newSingleThreadExecutor());
}
ANRequest anRequest = getRequestBuilder.build();
anRequest.getAsJSONObject(new JSONObjectRequestListener() {
@Override
public void onResponse(JSONObject response) {
// do anything with response
}
@Override
public void onError(ANError error) {
// handle error
}
});
ConnectionClass Listener to get current network quality and bandwidth
// Adding Listener
AndroidNetworking.setConnectionQualityChangeListener(new ConnectionQualityChangeListener() {
@Override
public void onChange(ConnectionQuality currentConnectionQuality, int currentBandwidth) {
// do something on change in connectionQuality
}
});
// Removing Listener
AndroidNetworking.removeConnectionQualityChangeListener();
// Getting current ConnectionQuality
ConnectionQuality connectionQuality = AndroidNetworking.getCurrentConnectionQuality();
if(connectionQuality == ConnectionQuality.EXCELLENT) {
// do something
} else if (connectionQuality == ConnectionQuality.POOR) {
// do something
} else if (connectionQuality == ConnectionQuality.UNKNOWN) {
// do something
}
// Getting current bandwidth
int currentBandwidth = AndroidNetworking.getCurrentBandwidth(); // Note : if (currentBandwidth == 0) : means UNKNOWN
Getting Analytics of a request by setting AnalyticsListener on that
AndroidNetworking.download(url,dirPath,fileName)
.setTag("downloadTest")
.setPriority(Priority.MEDIUM)
.build()
.setAnalyticsListener(new AnalyticsListener() {
@Override
public void onReceived(long timeTakenInMillis, long bytesSent, long bytesReceived, boolean isFromCache) {
Log.d(TAG, " timeTakenInMillis : " + timeTakenInMillis);
Log.d(TAG, " bytesSent : " + bytesSent);
Log.d(TAG, " bytesReceived : " + bytesReceived);
Log.d(TAG, " isFromCache : " + isFromCache);
}
})
.setDownloadProgressListener(new DownloadProgressListener() {
@Override
public void onProgress(long bytesDownloaded, long totalBytes) {
// do anything with progress
}
})
.startDownload(new DownloadListener() {
@Override
public void onDownloadComplete() {
// do anything after completion
}
@Override
public void onError(ANError error) {
// handle error
}
});
Note : If bytesSent or bytesReceived is -1 , it means it is unknown
Getting OkHttpResponse in Response
AndroidNetworking.get("https://fierce-cove-29863.herokuapp.com/getAnUserDetail/{userId}")
.addPathParameter("userId", "1")
.setTag(this)
.setPriority(Priority.LOW)
.setUserAgent("getAnUser")
.build()
.getAsOkHttpResponseAndParsed(new TypeToken<User>() {
}, new OkHttpResponseAndParsedRequestListener<User>() {
@Override
public void onResponse(Response okHttpResponse, User user) {
// do anything with okHttpResponse and user
}
@Override
public void onError(ANError anError) {
// handle error
}
});
Making Synchronous Request
ANRequest request = AndroidNetworking.get("https://fierce-cove-29863.herokuapp.com/getAllUsers/{pageNumber}")
.addPathParameter("pageNumber", "0")
.addQueryParameter("limit", "3")
.build();
ANResponse<List<User>> response = request.executeForObjectList(User.class);
if (response.isSuccess()) {
List<User> users = responseTwo.getResult();
} else {
//handle error
}
How caching works ?
- First of all the server must send cache-control in header so that is starts working.
- Response will be cached on the basis of cache-control max-age,max-stale.
- If internet is connected and the age is NOT expired it will return from cache.
- If internet is connected and the age is expired and if server returns 304(NOT MODIFIED) it will return from cache.
- If internet is NOT connected if you are using getResponseOnlyIfCached() - it will return from cache even it date is expired.
- If internet is NOT connected , if you are NOT using getResponseOnlyIfCached() - it will NOT return anything.
- If you are using getResponseOnlyFromNetwork() , it will only return response after validation from server.
- If cache-control is set, it will work according to the max-age,max-stale returned from server.
- If internet is NOT connected only way to get cache Response is by using getResponseOnlyIfCached().
Enabling Logging
AndroidNetworking.enableLogging(); // simply enable logging
AndroidNetworking.enableLogging(LEVEL.HEADERS); // enabling logging with level
Enabling GZIP From Client to Server
// Enabling GZIP for Request (Not needed if your server doesn't support GZIP Compression), anyway responses
// from server are automatically unGzipped if required. So enable it only if you need your request to be
// Gzipped before sending to server(Make sure your server support GZIP Compression).
OkHttpClient okHttpClient = new OkHttpClient().newBuilder()
.addInterceptor(new GzipRequestInterceptor())
.build();
AndroidNetworking.initialize(getApplicationContext(),okHttpClient);
IMPORTANT NOTE
- Use IMMEDIATE Priority with caution - use is at appropriate place only when 1 or 2 (at max 2)IMMEDIATE request is required at instant.Otherwise use HIGH Priority.
Known Bug : As present if you are using GZIP Interceptor from client to server, Upload progress is not working perfectly in Multipart.
If you are using Proguard with Gradle build system (which is usually the case), you don't have to do anything. The appropriate Proguard rules will be automatically applied. If you still need the rules applied in
proguard-rules.pro, it is as follows:-dontwarn okio.**
Fast Android Networking Library supports
- Fast Android Networking Library supports all types of HTTP/HTTPS request like GET, POST, DELETE, HEAD, PUT, PATCH
- Fast Android Networking Library supports downloading any type of file
- Fast Android Networking Library supports uploading any type of file (supports multipart upload)
- Fast Android Networking Library supports cancelling a request
- Fast Android Networking Library supports setting priority to any request (LOW, MEDIUM, HIGH, IMMEDIATE)
- Fast Android Networking Library supports RxJava
As it uses OkHttp as a networking layer, it supports:
- Fast Android Networking Library supports HTTP/2 support allows all requests to the same host to share a socket
- Fast Android Networking Library uses connection pooling which reduces request latency (if HTTP/2 isn’t available)
- Transparent GZIP shrinks download sizes
- Fast Android Networking Library supports response caching which avoids the network completely for repeat requests
Difference over other Networking Library
- In Fast Android Networking Library, OkHttpClient can be customized for every request easily — like timeout customization, etc. for each request.
- As Fast Android Networking Library uses OkHttp and Okio, it is faster.
- Single library for all type of networking.
- Supports RxJava, RxJava2 -> Check here
- Current bandwidth and connection quality can be obtained to decide logic of code.
- Executor can be passed to any request to get the response in another thread.
- Complete analytics of any request can be obtained.
- All types of customization are possible.
- Immediate Request really is immediate now.
- Prefetching of any request can be done so that it gives instant data when required from the cache.
- Proper request canceling.
- Prevents cancellation of a request if it’s completed more than a specific threshold percentage.
- A simple interface to make any type of request.
- Proper Response Caching — which leads to reduced bandwidth usage.
TODO
- Integration with other library
- And of course many many features and bug fixes
