Android拍照且将图片上传至服务器

MainActivity如下:

package cc.cn;

import java.io.File;
import java.io.IOException;
import cc.cn.UploadImageThread.UploadImageListener;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.os.Environment;
import android.provider.MediaStore;
import android.view.View;
import android.widget.Button;

/**
 * Demo描述:
 * 利于httpmime-4.1.3.jar实现图片的上传
 */
public class MainActivity extends Activity {
	private Button mCameraButton;
	private File imageFile;
	private Context mContext;
	private UploadImageThread mUploadImageThread;
	private final int REQUEST_CAMERA = 9527;
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		init();
	}

	private void init() {
		mContext=this;
		mCameraButton = (Button) findViewById(R.id.button);
		mCameraButton.setOnClickListener(new View.OnClickListener() {
			@Override
			public void onClick(View v) {
				startCamera();
			}
		});
	}

	public void startCamera() {
		String state = Environment.getExternalStorageState();
		if (state.equals(Environment.MEDIA_MOUNTED)) {
			String saveDir = Environment.getExternalStorageDirectory()+ "/test";
			File imageDir = new File(saveDir);
			if (!imageDir.exists()) {
				imageDir.mkdir();
			}
			imageFile = new File(saveDir, "floor1.jpg");
			if (!imageFile.exists()) {
				try {
					imageFile.createNewFile();
				} catch (IOException e) {
					e.printStackTrace();
					return;
				}
			}
			Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
			intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(imageFile));
			startActivityForResult(intent, REQUEST_CAMERA);
		}

	}

	@Override
	protected void onActivityResult(int requestCode, int resultCode, Intent data) {
		super.onActivityResult(requestCode, resultCode, data);
		switch (requestCode) {
		case REQUEST_CAMERA:
			if (resultCode != RESULT_OK) {
				return;
			}
			if (imageFile != null && imageFile.exists()) {
				mUploadImageThread= new UploadImageThread(imageFile);
				mUploadImageThread.setUploadImageListener(new UploadImageListener(){
					@Override
					public void uploadImageFail() {
						System.out.println("----> 图片上传失败");
					}

					}});
				mUploadImageThread.start();
			}
			break;
		default:
			break;
		}
	}

}

UploadImageThread如下:

		mUploadImageListener=uploadImageListener;
	}
	
	public interface UploadImageListener{
		public void uploadImageFail();

	}

	@Override
	public void run() {
		HttpPost httppost = new HttpPost(serverURL);

		httpclient.getParams().setParameter
		(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);

		MultipartEntity entity = new MultipartEntity

		try {

		} catch (Exception e) {

	}
}

main.xml如下:
