PC客户端与Android实现图片传送

PC服务端，用于发送图片

import java.io.DataOutputStream;
import java.io.FileInputStream;
import java.io.IOException;
import java.net.InetSocketAddress;
import java.net.ServerSocket;
import java.net.Socket;


public class Server {
	public static void main(String[] args) {
		try {
			ServerSocket server = new ServerSocket();
			server.bind(new InetSocketAddress(33336));
			Socket socket = server.accept();
			//socket.getInetAddress();
			DataOutputStream dos = new DataOutputStream(socket.getOutputStream());
			FileInputStream fis = new FileInputStream("E:/workspace/android/Server/test.png");
			int size = fis.available();
			byte[] data = new byte[size];
			fis.read(data);
			dos.writeInt(size);
			dos.write(data);
			dos.flush();
			dos.close();
			fis.close();
			socket.close();
			server.close();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}

Android客户端用于接收图片并展示

package com.tw;

import java.io.ByteArrayOutputStream;
import java.io.DataInputStream;
import java.io.IOException;
import java.net.Socket;

import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.Bitmap.CompressFormat;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.os.Handler;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;

public class TestActivity extends Activity {

	private ImageView imageView = null;
	private Bitmap bmp = null;
	
	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);

		imageView = (ImageView) findViewById(R.id.imageView1);
		Button btn = (Button) findViewById(R.id.button1);
		btn.setOnClickListener(new OnClickListener() {
			public void onClick(View v) {

				Thread t = new Thread() {
					@Override
					public void run() {
						super.run();
						Socket socket = null;
						try {
							socket = new Socket("192.168.102.67", 33336);
							DataInputStream dataInput = new DataInputStream(
									socket.getInputStream());
							int size = dataInput.readInt();
							byte[] data = new byte[size];
							// dataInput.readFully(data);
							int len = 0;
							while (len < size) {
								len += dataInput.read(data, len, size - len);
							}

							ByteArrayOutputStream outPut = new ByteArrayOutputStream();
							bmp = BitmapFactory.decodeByteArray(data, 0,
									data.length);
							bmp.compress(CompressFormat.PNG, 100, outPut);
							//imageView.setImageBitmap(bmp);
							myHandler.obtainMessage().sendToTarget();
						} catch (IOException e) {
							e.printStackTrace();
						} finally {
							try {
								socket.close();
							} catch (IOException e) {
								e.printStackTrace();
							}
						}
					}
				};
				t.start();
			}
		});
	}
	
	private Handler myHandler = new Handler(){
		public void handleMessage(android.os.Message msg) {
			imageView.setImageBitmap(bmp);
		};
	};

}

你好，运行时出现如下问题：

E/Trace(15019): error opening trace file: No such file or directory (2)

E/PhonePolicy(15019): Could not preload class for phone policy: com.android.internal.policy.impl.PhoneWindow$ContextMenuCallback
请问，怎么解决

不好意思，我忘了改IP地址了，对的没问题。
