既有适合小白学习的零基础资料，也有适合3年以上经验的小伙伴深入学习提升的进阶课程，涵盖了95%以上鸿蒙开发知识点，真正体系化！

由于文件比较多，这里只是将部分目录截图出来，全套包含大厂面经、学习笔记、源码讲义、实战项目、大纲路线、讲解视频，并且后续会持续更新

需要这份系统化的资料的朋友，可以戳这里获取

Fast Android Networking Library 可以包含在任何 Android 应用程序中。

Fast Android Networking Library 支持 Android 2.3 (Gingerbread) 及更高版本。

在您的应用程序中使用快速 Android 网络库

将此添加到您的 build.gradle

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

如果清单中不存在，请不要忘记在清单中添加互联网权限

<uses-permission android:name="android.permission.INTERNET" />

然后在应用类的 onCreate() 方法中初始化：

AndroidNetworking.initialize(getApplicationContext());

通过一些自定义对其进行初始化，因为它使用OkHttp作为网络层，您可以在初始化时传递自定义 okHttpClient。

// Adding an Network Interceptor for Debugging purpose :
OkHttpClient okHttpClient = new OkHttpClient() .newBuilder()
                        .addNetworkInterceptor(new StethoInterceptor())
                        .build();
AndroidNetworking.initialize(getApplicationContext(),okHttpClient);

使用带有 Jackson Parser 的快速 Android 网络

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


// Then set the JacksonParserFactory like below
AndroidNetworking.setParserFactory(new JacksonParserFactory());
发出 GET 请求
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
                    }
                });
发出 POST 请求
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
                    }
                });

您还可以像这样在 POST 请求中发布 java 对象、json、文件等。

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
                    }
                });
将它与您自己的 JAVA 对象一起使用 - 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 --*/

###从服务器下载文件

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    
                    }
                });

###上传文件到服务器

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 
                    }
                 });
在另一个线程执行器中获取响应和完成

（注意：错误和进度将始终在应用程序的主线程中返回）

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 
                    }
                 });

###如果请求已完成给定阈值，则设置不取消请求的百分比阈值

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    
                    }
                });

###取消请求。

任何带有给定标签的请求都可以被取消。就这样吧。

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.
从网络加载图像到 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);

###使用某些指定参数从 url 获取位图

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
                    }
                });

###错误代码处理

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());
   }
}

###从缓存中删除位图或清除缓存

AndroidNetworking.evictBitmap(key); // remove a bitmap with key from LruCache
AndroidNetworking.evictAllBitmap(); // clear LruCache
预取请求（以便在需要时立即从缓存中返回）
AndroidNetworking.get("https://fierce-cove-29863.herokuapp.com/getAllUsers/{pageNumber}")
                .addPathParameter("pageNumber", "0")
                .addQueryParameter("limit", "30")
                .setTag(this)
                .setPriority(Priority.LOW)
                .build()
                .prefetch();
为特定请求自定义 OkHttpClient
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
                    }
                });
提出条件请求（构建请求）

ConnectionClass Listener 获取当前网络质量和带宽
// 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
通过设置 AnalyticsListener 来获取请求的分析
