Fast Android Networking Library

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 There are some libraries but they are outdated.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 build.gradle

implementation 'com.amitshekhar.android:android-networking:1.0.2'

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

implementation 'com.amitshekhar.android:jackson-android-networking:1.0.2'

// Then set the JacksonParserFactory like below
AndroidNetworking.setParserFactory(new JacksonParserFactory());

Making a GET Request

AndroidNetworking.get("https://fierce-cove-29863.herokuapp.com/getAllUsers/{pageNumber}")
                 .addPathParameter("pageNumber", "0")
                 .addQueryParameter("limit", "3")
                 .addHeaders("token", "1234")
                 .setTag("test")
                 .setPriority(Priority.LOW)
                 .build()
                 .getAsJSONArray(new JSONArrayRequestListener() {
                    @Override
                    public void onResponse(JSONArray response) {
                      // do anything with response
                    }
                    @Override
                    public void onError(ANError error) {
                      // handle error
                    }
                });

Making a POST Request

AndroidNetworking.post("https://fierce-cove-29863.herokuapp.com/createAnUser")
                 .addBodyParameter("firstname", "Amit")
                 .addBodyParameter("lastname", "Shekhar")
                 .setTag("test")
                 .setPriority(Priority.MEDIUM)
                 .build()
                 .getAsJSONObject(new JSONObjectRequestListener() {
                    @Override
                    public void onResponse(JSONObject response) {
                      // do anything with response
                    }
                    @Override
                    public void onError(ANError error) {
                      // handle error
                    }
                });

You can also post java object, json, file, etc in POST request like this.

User user = new User();
user.firstname = "Amit";
user.lastname = "Shekhar";

AndroidNetworking.post("https://fierce-cove-29863.herokuapp.com/createUser")
                 .addBodyParameter(user) // posting java object
                 .setTag("test")
                 .setPriority(Priority.MEDIUM)
                 .build()
                 .getAsJSONArray(new JSONArrayRequestListener() {
                    @Override
                    public void onResponse(JSONArray response) {
                      // do anything with response
                    }
                    @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()
                 .getAsJSONArray(new JSONArrayRequestListener() {
                    @Override
                    public void onResponse(JSONArray response) {
                      // do anything with response
                    }
                    @Override
                    public void onError(ANError error) {
                      // handle error
                    }
                });
                
AndroidNetworking.post("https://fierce-cove-29863.herokuapp.com/postFile")
                 .addFileBody(file) // posting any type of file
                 .setTag("test")
                 .setPriority(Priority.MEDIUM)
                 .build()
                 .getAsJSONObject(new JSONObjectRequestListener() {
                    @Override
                    public void onResponse(JSONObject response) {
                      // do anything with response
                    }
                    @Override
                    public void onError(ANError error) {
                      // handle error
                    }
                });

Using it with your own JAVA Object - JSON Parser

/*--------------Example One -> Getting the userList----------------*/
AndroidNetworking.get("https://fierce-cove-29863.herokuapp.com/getAllUsers/{pageNumber}")
                .addPathParameter("pageNumber", "0")
                .addQueryParameter("limit", "3")
                .setTag(this)
                .setPriority(Priority.LOW)
                .build()
                .getAsObjectList(User.class, new ParsedRequestListener<List<User>>() {
                    @Override
                    public void onResponse(List<User> users) {
                      // do anything with response
                      Log.d(TAG, "userList size : " + users.size());
                      for (User user : users) {
                        Log.d(TAG, "id : " + user.id);
                        Log.d(TAG, "firstname : " + user.firstname);
                        Log.d(TAG, "lastname : " + user.lastname);
                      }
                    }
                    @Override
                    public void onError(ANError anError) {
                     // handle error
                    }
                });
/*--------------Example Two -> Getting an user----------------*/
AndroidNetworking.get("https://fierce-cove-29863.herokuapp.com/getAnUserDetail/{userId}")
                .addPathParameter("userId", "1")
                .setTag(this)
                .setPriority(Priority.LOW)
                .build()
                .getAsObject(User.class, new ParsedRequestListener<User>() {
                     @Override
                     public void onResponse(User user) {
                        // do anything with response
                        Log.d(TAG, "id : " + user.id);
                        Log.d(TAG, "firstname : " + user.firstname);
                        Log.d(TAG, "lastname : " + user.lastname);
                     }
                     @Override
                     public void onError(ANError anError) {
                        // handle error
                     }
                 }); 
/*-- Note : YourObject.class, getAsObject and getAsObjectList are important here --*/

Downloading a file from server

AndroidNetworking.download(url,dirPath,fileName)
                 .setTag("downloadTest")
                 .setPriority(Priority.MEDIUM)
                 .build()
                 .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    
                    }
                });

Uploading a file to server

AndroidNetworking.upload(url)
                 .addMultipartFile("image",file)    
                 .addMultipartParameter("key","value")
                 .setTag("uploadTest")
                 .setPriority(Priority.HIGH)
                 .build()
                 .setUploadProgressListener(new UploadProgressListener() {
                    @Override
                    public void onProgress(long bytesUploaded, long totalBytes) {
                      // do anything with progress 
                    }
                 })
                 .getAsJSONObject(new JSONObjectRequestListener() {
                    @Override
                    public void onResponse(JSONObject response) {
                      // do anything with response                
                    }
                    @Override
                    public void onError(ANError error) {
                      // handle error 
                    }
                 });

Getting Response and completion in an another thread executor

(Note : Error and Progress will always be returned in main thread of application)

AndroidNetworking.upload(url)
                 .addMultipartFile("image",file)  
                 .addMultipartParameter("key","value")  
                 .setTag("uploadTest")
                 .setPriority(Priority.HIGH)
                 .build()
                 .setExecutor(Executors.newSingleThreadExecutor()) // setting an executor to get response or completion on that executor thread
                 .setUploadProgressListener(new UploadProgressListener() {
                    @Override
                    public void onProgress(long bytesUploaded, long totalBytes) {
                      // do anything with progress 
                    }
                 })
                 .getAsJSONObject(new JSONObjectRequestListener() {
                    @Override
                    public void onResponse(JSONObject response) {
                      // below code will be executed in the executor provided
                      // do anything with response                
                    }
                    @Override
                    public void onError(ANError error) {
                      // handle error 
                    }
                 });

Setting a Percentage Threshold For Not Cancelling the request if it has completed the given threshold

AndroidNetworking.download(url,dirPath,fileName)
                 .setTag("downloadTest")
                 .setPriority(Priority.MEDIUM)
                 .setPercentageThresholdForCancelling(50) // even if at the time of cancelling it will not cancel if 50% 
                 .build()                                 // downloading is done.But can be cancalled with forceCancel.
                 .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    
                    }
                });

Cancelling a request.

Any request with a given tag can be cancelled. Just do like this.

AndroidNetworking.cancel("tag"); // All the requests with the given tag will be cancelled.
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

      <com.androidnetworking.widget.ANImageView
          android:id="@+id/imageView"
          android:layout_width="100dp"
          android:layout_height="100dp"
          android:layout_gravity="center" />
          
      imageView.setDefaultImageResId(R.drawable.default);
      imageView.setErrorImageResId(R.drawable.error);
      imageView.setImageUrl(imageUrl);

Getting Bitmap from url with some specified parameters

AndroidNetworking.get(imageUrl)
                 .setTag("imageRequestTag")
                 .setPriority(Priority.MEDIUM)
                 .setBitmapMaxHeight(100)
                 .setBitmapMaxWidth(100)
                 .setBitmapConfig(Bitmap.Config.ARGB_8888)
                 .build()
                 .getAsBitmap(new BitmapRequestListener() {
                    @Override
                    public void onResponse(Bitmap bitmap) {
                    // 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.**
```
