二、核心架构设计：AIDL与OkHttpUtils的完美结合

2.1 整体架构图

2.2 进程间通信时序图

三、AIDL接口设计：标准化跨进程网络请求

3.1 AIDL接口定义（INetworkService.aidl）

// INetworkService.aidl
package com.zhy.http.okhttp.aidl;

import com.zhy.http.okhttp.aidl.RequestParams;
import com.zhy.http.okhttp.aidl.ResponseData;
import com.zhy.http.okhttp.aidl.INetworkCallback;

interface INetworkService {
    // 执行GET请求
    void get(String url, in RequestParams params, String requestId, INetworkCallback callback);
    
    // 执行POST请求
    void post(String url, in RequestParams params, String requestId, INetworkCallback callback);
    
    // 执行文件上传
    void uploadFile(String url, in RequestParams params, String requestId, INetworkCallback callback);
    
    // 执行文件下载
    void downloadFile(String url, String savePath, String requestId, INetworkCallback callback);
    
    // 取消请求
    void cancelRequest(String requestId);
    
    // 取消所有请求
    void cancelAllRequests();
    
    // 同步Cookie
    void syncCookie(String url, in List<String> cookies);
}

3.2 数据模型定义

RequestParams.aidl

// RequestParams.aidl
package com.zhy.http.okhttp.aidl;

parcelable RequestParams;

RequestParams.java

public class RequestParams implements Parcelable {
    private Map<String, String> headers;
    private Map<String, String> params;
    private Map<String, FileInfo> files; // 文件上传专用
    
    // Parcelable实现代码
    protected RequestParams(Parcel in) {
        headers = in.readHashMap(String.class.getClassLoader());
        params = in.readHashMap(String.class.getClassLoader());
        files = in.readHashMap(FileInfo.class.getClassLoader());
    }
    
    public static final Creator<RequestParams> CREATOR = new Creator<RequestParams>() {
        @Override
        public RequestParams createFromParcel(Parcel in) {
            return new RequestParams(in);
        }
        
        @Override
        public RequestParams[] newArray(int size) {
            return new RequestParams[size];
        }
    };
    
    @Override
    public int describeContents() {
        return 0;
    }
    
    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeMap(headers);
        dest.writeMap(params);
        dest.writeMap(files);
    }
    
    // Getter和Setter方法
}

ResponseData.aidl

// ResponseData.aidl
package com.zhy.http.okhttp.aidl;

parcelable ResponseData;

ResponseData.java

public class ResponseData implements Parcelable {
    private int code;
    private String data;
    private String message;
    private long networkTime;
    private float progress; // 进度信息，0-1
    private long totalSize; // 总大小，字节
    
    // Parcelable实现代码
    protected ResponseData(Parcel in) {
        code = in.readInt();
        data = in.readString();
        message = in.readString();
        networkTime = in.readLong();
        progress = in.readFloat();
        totalSize = in.readLong();
    }
    
    public static final Creator<ResponseData> CREATOR = new Creator<ResponseData>() {
        @Override
        public ResponseData createFromParcel(Parcel in) {
            return new ResponseData(in);
        }
        
        @Override
        public ResponseData[] newArray(int size) {
            return new ResponseData[size];
        }
    };
    
    @Override
    public int describeContents() {
        return 0;
    }
    
    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeInt(code);
        dest.writeString(data);
        dest.writeString(message);
        dest.writeLong(networkTime);
        dest.writeFloat(progress);
        dest.writeLong(totalSize);
    }
    
    // Getter和Setter方法
}

INetworkCallback.aidl

// INetworkCallback.aidl
package com.zhy.http.okhttp.aidl;

import com.zhy.http.okhttp.aidl.ResponseData;

interface INetworkCallback {
    // 请求成功回调
    void onSuccess(String requestId, in ResponseData response);
    
    // 请求失败回调
    void onFailure(String requestId, int errorCode, String errorMsg);
    
    // 进度更新回调
    void onProgress(String requestId, float progress, long total);
}

四、OkHttpUtils跨进程封装：核心实现

    @Override
    public void onCreate() {
        super.onCreate();
        // 初始化OkHttpUtils单例
        mOkHttpUtils = OkHttpUtils.getInstance();
        Log.d(TAG, "NetworkService onCreate: OkHttpUtils initialized");
    }
    
    private final INetworkService.Stub mBinder = new INetworkService.Stub() {
        @Override
        public void get(String url, RequestParams params, String requestId, INetworkCallback callback) {
            executeRequest(url, params, requestId, callback, RequestType.GET);
        }
        
        @Override
        public void post(String url, RequestParams params, String requestId, INetworkCallback callback) {
            executeRequest(url, params, requestId, callback, RequestType.POST);
        }
        
        // 其他方法实现...
        
        @Override
        public void cancelRequest(String requestId) {
            Call call = mRequestMap.remove(requestId);
            if (call != null && !call.isCanceled()) {

            }
            mCallbackMap.remove(requestId);
        }
    };
    
    private void executeRequest(String url, RequestParams params, String requestId, 
                               INetworkCallback callback, RequestType type) {
        // 保存回调
        mCallbackMap.put(requestId, callback);
        
        // 构建请求
        OkHttpRequestBuilder builder = type == RequestType.GET ? 
            OkHttpUtils.get() : OkHttpUtils.post();

4.3 主进程调用示例（MainActivity.java）

public class MainActivity extends AppCompatActivity {
    private NetworkClient mNetworkClient;
    private String mRequestId;
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        // 初始化网络客户端
        mNetworkClient = NetworkClient.getInstance(this);
        
        // 发起GET请求示例
        findViewById(R.id.btn_get).setOnClickListener(v -> sendGetRequest());
        
        // 发起POST请求示例
        findViewById(R.id.btn_post).setOnClickListener(v -> sendPostRequest());
        
        // 取消请求示例
        findViewById(R.id.btn_cancel).setOnClickListener(v -> cancelRequest());
    }
    
    private void sendGetRequest() {
        if (!mNetworkClient.isConnected()) {
            Toast.makeText(this, "网络服务未连接", Toast.LENGTH_SHORT).show();
            return;
        }
        
        // 生成唯一请求ID
        mRequestId = UUID.randomUUID().toString();

        RequestParams params = new RequestParams();
        Map<String, String> headers = new HashMap<>();
        headers.put("User-Agent", "OkHttpUtils-AIDL-Demo");

        queryParams.put("page", "1");
        queryParams.put("count", "20");
        params.setParams(queryParams);
        
        // 发起请求
        mNetworkClient.get("https://api.example.com/data", params, mRequestId, 
            new INetworkCallback.Stub() {
                @Override
                public void onSuccess(String requestId, ResponseData response) {
                    // 在UI线程处理成功结果
                    runOnUiThread(() -> {

                    runOnUiThread(() -> {
                        ProgressBar progressBar = findViewById(R.id.progress_bar);
                        progressBar.setProgress((int) (progress * 100));
                    });
                }
            });
    }
    
    private void sendPostRequest() {
        // 类似GET请求实现...
    }
    
    private void cancelRequest() {
        if (mRequestId != null && mNetworkClient.isConnected()) {
            try {
                mNetworkClient.cancelRequest(mRequestId);
                Toast.makeText(this, "请求已取消", Toast.LENGTH_SHORT).show();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }
    
    @Override
    protected void onDestroy() {
        super.onDestroy();
        // 取消当前请求
        cancelRequest();
    }
}

五、高级特性实现：解决跨进程通信难题

5.1 跨进程Cookie同步方案

PersistentCookieStore增强版

public class CrossProcessCookieStore implements CookieStore {
    private static final String PREFS_NAME = "CrossProcessCookiePrefs";
    private static final String COOKIE_KEY = "cookies";
    private final SharedPreferences mSharedPrefs;
    private final Context mContext;
    
    public CrossProcessCookieStore(Context context) {
        mContext = context;
        // 使用跨进程模式的SharedPreferences
        mSharedPrefs = context.getSharedPreferences(PREFS_NAME, 
            Context.MODE_PRIVATE | Context.MODE_MULTI_PROCESS);
    }
    
    @Override
    public void add(URI uri, HttpCookie cookie) {
        // 保存Cookie到共享偏好设置
        Set<String> cookies = getStoredCookies();
        cookies.add(encodeCookie(new SerializableHttpCookie(cookie)));
        mSharedPrefs.edit().putStringSet(COOKIE_KEY, cookies).apply();
        
        // 发送广播通知其他进程Cookie已更新

            HttpCookie cookie = decodeCookie(cookieString);
            if (shouldAcceptCookie(uri, cookie)) {

5.2 大文件上传/下载进度同步

带进度回调的FileCallback

public abstract class ProgressFileCallback extends FileCallBack {
    private final String mRequestId;
    private final INetworkCallback mCallback;
    
    public ProgressFileCallback(String destFileDir, String destFileName, 
                               String requestId, INetworkCallback callback) {
        super(destFileDir, destFileName);
        mRequestId = requestId;
        mCallback = callback;
    }
    
    @Override
    public void inProgress(float progress, long total, int id) {
        super.inProgress(progress, total, id);
        try {
            // 通过AIDL回调进度到主进程
            if (mCallback != null) {
                mCallback.onProgress(mRequestId, progress, total);
            }
        } catch (RemoteException e) {
            Log.e("ProgressCallback", "进度回调失败", e);
        }
    }
}

5.3 请求优先级与队列管理

优先级请求调度器

public class PriorityRequestQueue {
    private static final int MAX_RUNNING_REQUESTS = 3;
    private final PriorityBlockingQueue<RequestWrapper> mRequestQueue = 
        new PriorityBlockingQueue<>(10, new RequestComparator());
    private final List<Worker> mWorkers = new ArrayList<>();
    
    public PriorityRequestQueue() {
        // 初始化工作线程
        for (int i = 0; i < MAX_RUNNING_REQUESTS; i++) {
            Worker worker = new Worker();
            mWorkers.add(worker);
            worker.start();
        }
    }
    
    public void add(RequestWrapper request) {
        mRequestQueue.add(request);
    }
    
    public void cancel(String requestId) {
        // 遍历队列取消指定请求
        List<RequestWrapper> temp = new ArrayList<>();
        mRequestQueue.drainTo(temp);
        for (RequestWrapper wrapper : temp) {
            if (!wrapper.getRequestId().equals(requestId)) {
                mRequestQueue.add(wrapper);
            } else {
                wrapper.getCall().cancel();
            }
        }
    }
    
    private class Worker extends Thread {
        @Override
        public void run() {
            while (!interrupted()) {
                try {
                    RequestWrapper request = mRequestQueue.take();
                    if (!request.getCall().isCanceled()) {
                        request.getCall().enqueue(request.getCallback());
                    }
                } catch (InterruptedException e) {
                    interrupt();
                    break;
                }
            }
        }
    }
    
    private static class RequestComparator implements Comparator<RequestWrapper> {
        @Override
        public int compare(RequestWrapper lhs, RequestWrapper rhs) {
            // 优先级高的先执行
            return Integer.compare(rhs.getPriority(), lhs.getPriority());
        }
    }
    
    public static class RequestWrapper {
        private final Call mCall;
        private final Callback mCallback;
        private final String mRequestId;
        private final int mPriority;
        
        public RequestWrapper(Call call, Callback callback, String requestId, int priority) {
            mCall = call;
            mCallback = callback;
            mRequestId = requestId;
            mPriority = priority;
        }
        
        // Getter方法
    }
}

六、性能优化与最佳实践

6.1 跨进程通信性能优化策略

优化点	实现方案	性能提升
参数序列化	使用Parcelable替代Serializable	提升40-60%
回调管理	使用WeakReference引用回调	减少内存泄漏
请求合并	批量处理小请求	减少IPC次数30-50%
数据压缩	大响应数据压缩传输	减少带宽占用50-70%
Binder连接池	共享Binder连接	降低连接开销40%
异步回调	使用HandlerThread处理回调	避免阻塞主线程

6.2 异常处理与容错机制

public class NetworkErrorHandler {
    // 错误码定义
    public static final int ERROR_SERVICE_DISCONNECTED = 1001;
    public static final int ERROR_REQUEST_TIMEOUT = 1002;
    public static final int ERROR_PARCEL_EXCEPTION = 1003;
    
    // 错误处理映射表
    private static final Map<Integer, String> ERROR_MESSAGES = new HashMap<>();
    
    static {
        ERROR_MESSAGES.put(ERROR_SERVICE_DISCONNECTED, "网络服务已断开，请重试");
        ERROR_MESSAGES.put(ERROR_REQUEST_TIMEOUT, "请求超时，请检查网络");
        ERROR_MESSAGES.put(ERROR_PARCEL_EXCEPTION, "数据序列化失败");
    }
    
    public static void handleError(Exception e, String requestId, INetworkCallback callback) {
        try {
            if (e instanceof RemoteException) {
                callback.onFailure(requestId, ERROR_SERVICE_DISCONNECTED, 
                    ERROR_MESSAGES.get(ERROR_SERVICE_DISCONNECTED));
            } else if (e instanceof ParcelableException) {
                callback.onFailure(requestId, ERROR_PARCEL_EXCEPTION, 
                    ERROR_MESSAGES.get(ERROR_PARCEL_EXCEPTION));
            } else if (e instanceof SocketTimeoutException) {
                callback.onFailure(requestId, ERROR_REQUEST_TIMEOUT, 
                    ERROR_MESSAGES.get(ERROR_REQUEST_TIMEOUT));
            } else {
                callback.onFailure(requestId, 9999, "未知错误: " + e.getMessage());
            }
        } catch (RemoteException re) {
            Log.e("ErrorHandler", "处理错误时发生RemoteException", re);
        }
    }
    
    // 重试策略
    public static boolean shouldRetry(int errorCode, int retryCount) {
        // 只对特定错误码和重试次数小于3次的请求进行重试
        return (errorCode == ERROR_SERVICE_DISCONNECTED || errorCode == ERROR_REQUEST_TIMEOUT) && 
               retryCount < 3;
    }
    
    // 指数退避重试延迟计算
    public static long calculateRetryDelay(int retryCount) {
        return (long) (Math.pow(2, retryCount) * 1000); // 1s, 2s, 4s...
    }
}

6.3 内存泄漏防护措施

1. 使用弱引用保存AIDL回调

public class CallbackWrapper implements INetworkCallback {
    private final WeakReference<INetworkCallback> mCallbackRef;
    
    public CallbackWrapper(INetworkCallback callback) {
        mCallbackRef = new WeakReference<>(callback);
    }
    
    @Override
    public void onSuccess(String requestId, ResponseData response) throws RemoteException {
        INetworkCallback callback = mCallbackRef.get();
        if (callback != null) {
            callback.onSuccess(requestId, response);
        }
    }
    
    // 其他方法类似...
}

2. Activity生命周期管理

@Override
protected void onDestroy() {
    super.onDestroy();
    // 取消所有关联的请求
    if (mRequestId != null) {
        mNetworkClient.cancelRequest(mRequestId);
    }
    // 移除连接监听器
    mNetworkClient.removeConnectionListener(mConnectionListener);
}

七、完整项目结构与集成指南

7.1 项目模块划分

okhttputils-aidl-demo/
├── app/                      # 主应用模块(UI进程)
│   ├── src/main/
│   │   ├── java/com/zhy/demo/
│   │   │   ├── MainActivity.java
│   │   │   └── ...
│   │   └── aidl/com/zhy/http/okhttp/aidl/  # AIDL文件
│   └── build.gradle
│
├── networklibrary/           # 网络库模块(共享代码)
│   ├── src/main/
│   │   ├── java/com/zhy/http/okhttp/
│   │   │   ├── NetworkClient.java
│   │   │   ├── RequestParams.java
│   │   │   └── ...
│   │   └── aidl/com/zhy/http/okhttp/aidl/  # AIDL文件
│   └── build.gradle
│
└── networkservice/           # 网络服务模块(远程进程)
    ├── src/main/
    │   ├── java/com/zhy/http/okhttp/service/
    │   │   ├── NetworkService.java
    │   │   └── ...
    │   └── AndroidManifest.xml  # 声明独立进程
    └── build.gradle

7.2 配置独立进程

在networkservice模块的AndroidManifest.xml中声明独立进程：

<service
    android:name="com.zhy.http.okhttp.service.NetworkService"
    android:process=":network"  <!-- 独立进程 -->
    android:exported="false"
    android:permission="android.permission.INTERNET">
</service>

7.3 依赖配置

在app模块的build.gradle中添加依赖：

dependencies {
    implementation project(':networklibrary')
    implementation project(':networkservice')
    implementation 'com.squareup.okhttp3:okhttp:3.14.9'
    implementation 'com.google.code.gson:gson:2.8.9'
}

八、总结与扩展

8.1 本文核心要点回顾

• 跨进程网络请求架构采用AIDL+OkHttpUtils组合方案，实现网络请求集中管理
• AIDL接口设计需考虑参数序列化、回调机制和异常处理
• 通过服务端单例OkHttpUtils实例避免资源重复初始化
• 使用ConcurrentHashMap管理请求和回调，确保线程安全
• 实现Cookie跨进程同步、进度回调和请求优先级调度等高级特性
• 采用多种性能优化策略，包括数据压缩、请求合并和连接池等

8.2 进阶扩展方向

1. 请求拦截器链：实现跨进程的请求拦截器，支持日志记录、Token刷新等功能
2. 数据缓存策略：在远程进程实现二级缓存（内存+磁盘），减少重复网络请求
3. WebSocket支持：扩展AIDL接口支持WebSocket长连接，实现跨进程实时通信
4. 网络状态监听：在远程进程监听网络状态变化，自动重试请求
5. 性能监控：添加网络请求性能统计，输出请求耗时、成功率等指标
