android之拷贝assets下的资源文件到SD卡中(可以超过1M)

见博客 http://www.cnblogs.com/wainiwann/p/3274386.html

private void copyBigDataToSD(String strOutFileName) throws IOException 
    {  
        InputStream myInput;  
        OutputStream myOutput = new FileOutputStream(strOutFileName);  
        myInput = this.getAssets().open("yphone.zip");  
        byte[] buffer = new byte[1024];  
        int length = myInput.read(buffer);
        while(length > 0)
        {
            myOutput.write(buffer, 0, length); 
            length = myInput.read(buffer);
        }

        myOutput.flush();  
        myInput.close();  
        myOutput.close();        
    }
