About Fast Android Networking Library

Fast Android Networking is a third-party library that wraps OkHttp with fluent builders for GET/POST, file upload/download, image loading, and JSON parsing.

Historical reference — prefer a modern, Kotlin-first stack for new code. The library's last source-code release was v1.0.2 on 2018-07-10; the 1.0.3 and 1.0.4 tags published on 2024-08-18 bundle only Gradle/JitPack republishing changes — a git compare shows zero files under android-networking/src/ changed across the six-year gap. Every API on this page is a Java SAM-interface callback (JSONObjectRequestListener, DownloadListener, etc.) — there is no Kotlin or coroutine source in the repository, so the snippets below cannot be translated into idiomatic suspend-function form without reverting to the same callback shape. For new networking work on Android, prefer:

The remainder of this page is preserved as a reference for codebases that still depend on Fast Android Networking. Some snippets use try { ... } catch (JSONException e) { e.printStackTrace(); } — that pattern is illustrative of upstream sample code, not a recommended error-handling style; log via Log.e(...) or surface the failure to the caller in real code.

Requirements

The 1.0.4 module declares minSdkVersion 14 (Android 4.0, Ice Cream Sandwich) and compileSdkVersion 27 — see the pinned ext block in the root build.gradle at tag 1.0.4, unchanged since v1.0.2. Apps consuming it today are still bound by their own minSdkVersion and compileSdk.

Historical reference: using Fast Android Networking Library in your application

The library is distributed via JitPack. Add the JitPack repository to your top-level settings.gradle (or build.gradle if you still configure repositories there):

dependencyResolutionManagement {
    repositories {
        google()
        mavenCentral()
        maven { url 'https://jitpack.io' }
    }
}

Then add this in your module's build.gradle:

implementation 'com.github.amitshekhariitbhu.Fast-Android-Networking:android-networking:1.0.4'

Note: the older com.amitshekhar.android:android-networking artifact on Maven Central / JCenter has not been updated past 1.0.2. The 1.0.4 release is only published through JitPack with the com.github.amitshekhariitbhu.* coordinates above. See the upstream README.

For RxJava2 Support, check here.

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());

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", "Rohit");
    jsonObject.put("lastname", "Kumar");
} 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 
                    }
                 });

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());
   }
}
