兩部android設備通過服務器轉發實現通信簡單demo

編輯：關於Android編程

實現該通信的基本思路是：利用servlet服務器進行數據轉發，利用android設備（手機）長連接本文已定時器來模擬長連接，實現了兩部android手機內網通信。


1、作為終端的設備的設備主要是一個開機啟動後就啟動的一個服務，按照一定的時間間隔用http協議去請求服務器，查詢服務器的狀態，如果連接服務器，獲得的相應是開啟GPS信息收集，則在這個服務裡開啟已經安裝在該android手機上的GPS信息收集APP，然後通過Http的GET方式源源不斷的向服務器傳遞GPS信息。

關鍵代碼如下：

public class RunningServiceByPowerOn extends Service {
	private SharedPreferences mPreferences;
	public RunningServiceByPowerOn() {
		// TODO Auto-generated constructor stub
	}

	@Override
	public IBinder onBind(Intent intent) {
		// TODO Auto-generated method stub
		return null;
	}
	@Override
	public void onCreate() {
		// TODO Auto-generated method stub
		super.onCreate();
		mPreferences=getSharedPreferences("Config",MODE_PRIVATE);
		 timerTaskforGpsSwitch();
	}
	
	/**
	 * 每隔5s查詢一次
	 */
	private void timerTaskforGpsSwitch(){
		  Timer timer = new Timer();
		  Date d2 = new Date(System.currentTimeMillis());	
		  timer.schedule(new TimerTask() {
			
			@Override
			public void run() {
				Log.i("是否開啟GPS收集","定時器開啟");
				String spec="http://"+ConentValues.serverIp+":8080/MyServer/StartAction?mAction=find_gps_switcher1";
				URL url;
				 String str=null;
				try {
					url = new URL(spec);
					 str=HttpToServierUtils.connect(url);
					 if(str!=null&&str.equals("GPS_start")){
							//開啟GPS服務
						 Log.i("是否開啟GPS收集","開啟GPS信息收集服務");
							//Toast.makeText(getApplicationContext(),"開啟GPS信息收集服務",0).show();
						 //開啟一個應用
						 if(mPreferences.getBoolean("isStop", true)){
							 Intent intent = new Intent(Intent.ACTION_MAIN);
							 intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
							 intent.addCategory(Intent.CATEGORY_LAUNCHER);            
							 ComponentName cn = new ComponentName("com.yqq.gpsinfolocationstartreceiver", "com.yqq.gpsinfolocationstartreceiver.MainActivity");            
							 intent.setComponent(cn);
							 startActivity(intent);
							 mPreferences.edit().putBoolean("isStop", false).commit();
						 }
						 
						
						}
					 if(str!=null&&str.equals("GPS_stop")){
						 mPreferences.edit().putBoolean("isStop",true).commit();
					 }
						
				} catch (MalformedURLException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
				
			
				
			}
		},d2, 5000);
	}

}

Gps信息收集的關鍵代碼：

public class GpsInfoCollectionService extends Service {
	
	private Boolean D=true;
	private GPSinfoDao mGpSinfoDao;
	private LocationManager mLocationManager;
	private Location mLocation;
	Criteria criteria;
	private String provider;
	public GpsInfoCollectionService() {
		
	}

	@Override
	public IBinder onBind(Intent intent) {
		if(D){
			Log.i("GPS服務數據收集","IBinder()");
		}
		return null;
	}
	@Override
	public void onCreate() {
		if(D){
			Log.i("GPS服務數據收集","onCreate()");
		}
		super.onCreate();
 mLocationManager=(LocationManager)getSystemService(Context.LOCATION_SERVICE);  
 criteria = new Criteria();
 criteria.setAccuracy(Criteria.ACCURACY_FINE);//獲取精確的位置.
 criteria.setAltitudeRequired(true);
 criteria.setBearingRequired(true);
 criteria.setCostAllowed(true);
 criteria.setPowerRequirement(Criteria.POWER_LOW);
 criteria.setSpeedRequired(true);
        //判斷GPS是否正常啟動  
        if(!mLocationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)){  
            Toast.makeText(this, "請開啟GPS導航...", Toast.LENGTH_SHORT).show();  
          
            //返回開啟GPS導航設置界面  
            Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            startActivity(intent);   
		
	
        }
    	mGpSinfoDao=new GPSinfoDao(getApplicationContext());
    	timerTaskforGpsSwitch();
		
	}
	@Override
	public int onStartCommand(Intent intent, int flags, int startId) {
		if(D){
			Log.i("GPS服務數據收集","onStartCommand()");
		}
		  
	        
	         provider = mLocationManager.getBestProvider(criteria, true);
	         Log.i("<<<<",provider);
		
	     		
	        mLocationManager.requestLocationUpdates(provider, 300, 0.01f, new LocationListener() {
				
				@Override
				public void onStatusChanged(String provider, int status, Bundle extras) {
					// TODO Auto-generated method stub

					// TODO Auto-generated method stub
					
				}
				
				@Override
				public void onLocationChanged(Location location) {
					if(location==null){
						return;
					}
					//updateLocation(location);
					mLocation=location;
					new AsyncTask() {
						private String str=null;
						@Override
						protected Void doInBackground(Void... params) {
							
							String height=mLocation.getAltitude()+"";
							String longitude=mLocation.getLongitude()+"";
							String latitude=mLocation.getLatitude()+"";
							String name="Test";
							//http://172.22.122.1:8080/MyServer/MyTest?longitude=111&latitude=222&height=1000&name=Test

								mGpSinfoDao.addGpsInfo(info);
								info=null;*/
							return null;
						}
						@Override
						protected void onPostExecute(Void result) {
							
							
							Toast.makeText(getApplicationContext(), str,0).show();
							
						};
						
					}.execute();
	        
	    
				}
				
	        });
		return super.onStartCommand(intent, flags, startId);
	}
	
	@Override
	public void onDestroy() {
		if(D){
			Log.i("GPS服務數據收集","onDestroy()");
		}
		mGpSinfoDao=null;
		mLocationManager=null;
		mLocation=null;
		super.onDestroy();
	}
	
	/**
	 * 每隔5s查詢一次
	 */
	private void timerTaskforGpsSwitch(){
		  Timer timer = new Timer();
		  Date d2 = new Date(System.currentTimeMillis());	
		  timer.schedule(new TimerTask() {
			
			@Override
			public void run() {

					// TODO Auto-generated catch block
					e.printStackTrace();
				}
				
			
				
			}
		},d2, 5000);
	}

}

2、服務端利用servlet來處理各自的請求和響應

關鍵代碼：

（1）處理GPS信息上傳到服務器的servlet

public class MyTest extends HttpServlet {
	//private List infos;
	
	private GpsInfo info;
	@Override
	protected void doGet(HttpServletRequest req, HttpServletResponse resp)
			throws ServletException, IOException {
		doPost(req, resp);
	
	}

	@Override
	protected void doPost(HttpServletRequest req, HttpServletResponse resp)
			throws ServletException, IOException {
		req.setCharacterEncoding("UTF-8");
		resp.setContentType("text/html;charset=utf-8");
		resp.setCharacterEncoding("utf-8");
		PrintWriter  out=resp.getWriter();
		String nameAction=(String)req.getAttribute("nameAction");
		
		
		//String spec="http://"+ConentValues.serverIp+":8080/MyServer/MyTest?longitude="+longitude+"&latitude="+latitude+"&height="+height;			
		String longitude=req.getParameter("longitude");
		String latitude=req.getParameter("latitude");
		String height=req.getParameter("height");
		String name=req.getParameter("name");
		
		String mAction=req.getParameter("mAction");
		//查詢服務器端數據庫並獲得返回值
		
		
	
		if(mAction!=null&&mAction.equals("find_gps_switcher")){
			System.out.println("定時器服務查詢："+mAction);
		try {
			
			String result=DbUtis.getGPSStaus();
			if(result!=null&&result.equals("start_gps")){
				out.write("GPS_start");
				out.flush();
			}
			if(result!=null&&result.equals("end_gps")){
				out.write("GPS_stop");
				out.flush();
			}
		} catch (SQLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
			
				
				
				
			
		}
		
		try {
			 //上傳的服務器的數據
		
			
			
			if(longitude!=null&&latitude!=null&&height!=null){
				info=new GpsInfo();
				info.setLongitude(longitude);
				info.setLatitude(latitude);
				info.setHeight(height);
				info.setName(name);
				DbUtis.insertGpsInfos(info);
				System.out.println("游客終端上傳的數據："+info.toString());
				
				
			
			
			
				out.write("GPS數據已經上傳到服務器");
				
				
				out.flush();
			}
			
				
			
				
			
			
	
		} catch (SQLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}finally{
			/*if(out!=null){
				out.close();
			}*/
			
			
		}
		
	}

控制端主要是發送幾個GET方式的請求，這裡就不再貼代碼了。

幾個請求：

"http://"+ConentValues.serverIp+":8080/MyServer/MyTest?mAction=find_gps_switcher";

"http://"+ConentValues.serverIp+":8080/MyServer/StartAction?mAction=find_gps_switcher1";

http://172.22.122.1:8080/MyServer/MyTest?longitude=111&latitude=222&height=1000&name=Test

http://172.22.122.1:8080/MyServer/MyTest?namereq=Test
