求教BinCompiler在安卓下的使用方法

[creamtank]

BinReader.java

package com.test;
 

import java.io.InputStream;
import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;




 
public class BinReader extends Activity {

	//读取指定文件并返回字节数组
	public byte[] readFile(String binfile, int pos)
	 {
	  byte buffer[];
	  int len;
	  try {
	   InputStream is = this.getClass().getResourceAsStream("/" + binfile);
	   is.skip(pos);
	   len  = (is.read() & 0xFF) << 24;
	   len  = (is.read() & 0xFF) << 16;
	   len  = (is.read() & 0xFF) << 8;
	   len  = (is.read() & 0xFF);
	   buffer = new byte[len];
	  
	   is.read(buffer, 0, buffer.length);
	   is.close();
	   is = null;
	  
	   System.gc();
	  } catch (Exception e) {
	   buffer = null;
	   e.printStackTrace();
	   System.gc();
	   return null;
	  }

	  return buffer;
	 } 

	/**************************************************************************************
	 * Reads a file from the BIN file and return data as an Image
	 **************************************************************************************/
	public Bitmap readImage(String binfile, long pos)
	{
		byte buffer[];
		int len;

		try {
			InputStream is = this.getClass().getResourceAsStream("/" + binfile);
			
			is.skip(pos);
			
			len  = (is.read() & 0xFF) << 24;
			len  |= (is.read() & 0xFF) << 16;
			len  |= (is.read() & 0xFF) << 8;
			len  |= (is.read() & 0xFF);

			buffer = new byte[len];
		
			is.read(buffer, 0, buffer.length);

			is.close();
			is = null;
		
			System.gc();
		} catch (Exception e) {
			buffer = null;
			e.printStackTrace();
			System.gc();
			return null;
		}

		return BitmapFactory.decodeByteArray(buffer, 0, buffer.length);
	}
}

Main.java中的调用方法

BinReader br;
Bitmap image;
br.readImage("image.bin", 0); 

我有2张png的图 用BinCompiler压成一个二进制bin文件[image.bin]
想在安卓程序中显示，不用xml布局，

实在是找不到多少文档，资源啥的，
特来跪求高人帮忙啊~~~~

难道没人知道么？？？？
