Android進程間通信LocalSocket

進程間通信，肯定會有讀寫等耗時操作，所以要把代碼寫在子線程中。

一、服務端LocalServerSocket

1、創建服務端LocalServerSocket的對象

server = new LocalServerSocket ("ysy_data");

2、監聽連接，獲取服務端LocalSocket對象。

client = server.accept ();

3、獲取輸入輸出流。

os = new PrintWriter (client.getOutputStream ());
is = new BufferedReader (new InputStreamReader (client.getInputStream ()));

4、接收客戶端發過來的數據

String result = "";
while (true) try {
    result = is.readLine ();
    Log.i (TAG, "服務端接到的數據爲：" + result);
    //把數據帶回activity顯示
    Message msg = handler.obtainMessage ();
    msg.obj = result;
    msg.arg1 = 0x11;
    handler.sendMessage (msg);
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace ();
}

5、發送數據

//發數據
public void send (String data) {
    if (os != null) {
        os.println (data);
        os.flush ();
    }
}

6、關閉流，釋放資源

try {
    if (os != null) {
        os.close ();
    }
    if (is != null) {
        is.close ();
    }
    if (client != null) {
        client.close ();
    }
    if (server != null) {
        server.close ();
    }
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace ();
}

二、客戶端LocalSocket

1、創建客戶端對象

client = new LocalSocket ();

2、連接服務端

client.connect (new LocalSocketAddress (NAME));

3、獲取輸入輸出流

os = new PrintWriter (client.getOutputStream ());
is = new BufferedReader (new InputStreamReader (client.getInputStream ()));

4、讀取服務端發送過來的數據

String result = "";
while (true) {
    try {
        result = is.readLine ();
        Log.i (TAG, "客戶端接到的數據爲：" + result);
        //將數據帶回acitvity顯示
        Message msg = handler.obtainMessage ();
        msg.arg1 = 0x12;
        msg.obj = result;
        handler.sendMessage (msg);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace ();
    }
}

5、發送數據

//發數據
public void send (String data) {
    if (os != null) {
        os.println (data);
        os.flush ();
    }
}

6、關閉流，釋放資源

try {
    if (os != null) {
        os.close ();
    }
    if (is != null) {
        is.close ();
    }
    if (client != null) {
        client.close ();
    }
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace ();
}
