c ++控制台应用程序与android应用程序的连接 [英] c++ Console application connection to android app

问题描述

我必须在android应用程序和c ++控制台应用程序之间建立连接：
假设控制台应用程序是客户端，它具有4条命令来从服务器（即android设备）获取数据。换句话说，我需要在控制台应用程序中显示设备信息（BT / WIFI开/关，BATTERY LVL）。

我创建了客户端，我也有我必须检查的代码（例如BT是否已打开）。
我唯一缺少的是它们之间的连接，我没有服务器代码方面的经验，我需要您的帮助，这是如何完成的或教程的链接导致我找不到它们。 / p>

android代码：

  @Override 
受保护的无效onCreate（Bundle savedInstanceState）{
 super.onCreate（savedInstanceState）; 
 setContentView（R.layout.activity_main）; 
 
 // IMEI初始化
 TelephonyManager telephonyManager =（TelephonyManager）getSystemService（Context.TELEPHONY_SERVICE）; 
 IMEI = telephonyManager.getDeviceId（）; 
 
 //软件版本初始化
 PackageInfo pInfo = null; 
 try {
 pInfo = getPackageManager（）。getPackageInfo（getPackageName（），0）; 
} catch（PackageManager.NameNotFoundException e）{
 e.printStackTrace（）; 
} 
 int SoftwareVersion = pInfo.versionCode; 
 
 
 //电池lvl初始化
 battery = Library.getBatteryLevel（this）; 
 
 // android id初始化
 android_id = Secure.getString（this.getContentResolver（），
 Secure.ANDROID_ID）; 
 
 // Android可用性初始化
 internetaval = Library.isNetworkAvailable（this）; 
 
 //完成初始化< ~~ 
 
 
 
 
 TextView tv =（TextView）findViewById（R.id。电视1）； 
 tv.setText（ + internetaval）; 
 
 Library.setWifi（this，false）; 
 
 
} 
  

解决方案

尽管您的问题过于笼统，有待解决，但我将为您提供一个可以忽略的线索。

使用Java网络API（套接字编程），您应该选择一个端口号并开始监听。这里的关键是，您的Android设备和运行该C ++应用程序的计算机必须连接到同一网络（例如WLAN或LAN）。

在这种情况下两个设备都将分配两个唯一的IP地址，也可以手动设置它们。

在客户端（C ++）中，您应该创建一个TCP套接字并连接到指定端口号的Android设备的IP地址。因此，通过这种方式，您可以将C ++连接到在Android应用中运行的Java服务器。同样在另一面，您应该使用Java套接字API在Android应用中接受传入连接。

建议：请勿从头开始创建应用，请始终使用众所周知的图书馆。这使开发过程更快，更有趣。 ：）

I have to make a connection between android app and c++ console application: The console application is suppose to be the client side which has 4 commands to get data from the server which is the android device. In other words I need to display the device info (BT/WIFI on/off, BATTERY LVL) in the console application.

I created the client side and I also have the code for the things I have to check(if BT is on for example). The only thing I'm missing is the connection between these, I have no experience in server code, and I need your help with this, how is this done or links for tutorials cause I didn't find some.

the android code:

  @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    //IMEI init
    TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
    IMEI = telephonyManager.getDeviceId();

    //software version init
    PackageInfo pInfo = null;
    try {
        pInfo = getPackageManager().getPackageInfo(getPackageName(), 0);
    } catch (PackageManager.NameNotFoundException e) {
        e.printStackTrace();
    }
    int SoftwareVersion = pInfo.versionCode;


    //battery lvl init
    battery = Library.getBatteryLevel(this);

    //android id init
    android_id = Secure.getString(this.getContentResolver(),
            Secure.ANDROID_ID);

    //android availability init
    internetaval = Library.isNetworkAvailable(this);

    //finish init  <<~~




    TextView tv = (TextView) findViewById(R.id.tv1);
    tv.setText(" " + internetaval);

    Library.setWifi(this,false);


}

解决方案

Although your question is too broad and subject to being closed, I will give you an overlook clue to be implemented.

Using Java network APIs (socket programming) you should pick a port number and start listening on. The key thing here is that your Android device and your computer running that C++ app must be connected to the same network (for example a WLAN or LAN).

In this case both your devices will be assigned two unique IP address, you can also set them manually.

In your client side (C++), you should create a TCP socket and connect to IP address of your Android device given its port number. So, using this way you can connect your C++ to your Java server running in your Android app. Also in other side, you should accept incoming connects in your Android app using Java socket APIs.

• Java Networking Examples

Suggestion: Never create your apps from scratch, always use well-known libraries. This makes development process more quicker and also more enjoyable. :)
