我正在编写一个 android 应用程序,它将图像发送到运行 java 应用程序的服务器,它以一种非常奇怪的方式工作!
这是我所做的
- 在桌面上编译并运行 Java 应用程序,接收部分充当服务器
- 编译、部署并运行必须将图像发送到服务器的 android 部分。android 应用程序完成执行,但 java 应用程序没有
- 运行具有再次发送图像的代码的 android 应用程序活动,这一次,android 应用程序进度对话框卡住了,但是,java 应用程序完成执行并且图像被成功传输...
以下是 Java 应用程序的 RECEIVE 部分的代码:
class ProjectServer
{
ServerSocket serSock;
Socket sock;
BufferedReader in;
PrintWriter out;
public static void main(String ar[])
{
try
{
ProjectServer cs=new ProjectServer();
cs.startServer();
}
catch(Exception e)
{
}
}
public void startServer()
{
try
{
serSock=new ServerSocket(8070);
System.out.println("Waiting for client...");
sock=serSock.accept();
System.out.println("Connections done");
//Accept File
System.out.println("Connected");
//receive code
int filesize=450660;
int bytesRead;
int current=0;
// receive file
byte [] mybytearray = new byte [filesize];
InputStream is = sock.getInputStream();
FileOutputStream fos = new FileOutputStream("C:\\Project Server\\Capture.png");
BufferedOutputStream bos = new BufferedOutputStream(fos);
bytesRead = is.read(mybytearray,0,mybytearray.length);
current = bytesRead;
do {
bytesRead =
is.read(mybytearray, current, (mybytearray.length-current));
if(bytesRead >= 0) current += bytesRead;
} while(bytesRead > -1);
bos.write(mybytearray, 0 , current);
bos.flush();
System.out.println("end-start");
}
catch(Exception e)
{
System.out.println(e);
e.printStackTrace();
}
}
}
以下是 Android 应用上 SEND 部分的代码:
package com.site.custom;
public class Act2 extends Activity
{
private ProgressDialog pd;
private String serverIP="58.146.100.187";
private BufferedReader in;
private PrintWriter out;
private String path;
private Socket cliSock;
public void onCreate(Bundle onCreateInstance)
{
super.onCreate(onCreateInstance);
setContentView(R.layout.act2);
this.setTitle("This has started");
path=getIntent().getStringExtra("path");
//Establish Connection
try
{
cliSock=new Socket(serverIP,8070);
in=new BufferedReader(new InputStreamReader(cliSock.getInputStream()));
((TextView)findViewById(R.id.tview)).setText(path);
}
catch(Exception e)
{
Log.v("MERA MSG",e.toString());
}
//Send file
ProgressDialog pd=ProgressDialog.show(this, "Sending image", "Image chosen:"+path.substring(path.lastIndexOf("//")+1),false,true);
try
{
File myFile = new File (path);
System.out.println((int)myFile.length());
byte[] mybytearray = new byte[450560];
FileInputStream fis = new FileInputStream(myFile);
BufferedInputStream bis = new BufferedInputStream(fis);
bis.read(mybytearray,0,mybytearray.length);
OutputStream os = cliSock.getOutputStream();
System.out.println("Sending...");
os.write(mybytearray,0,mybytearray.length);
os.flush();
System.out.println("Completed");
pd.dismiss();
System.out.println("Done");
}
catch(Exception e)
{
Log.v("MERA MSG",e.toString());
}
}
}
