linux下使用方式如下

 将文件 libbz2.so.1.0.6  复制到 /usr/lib/
 [root@xsmdmgr bsdiff4.3-linux]#cp -rf ./libbz2.so.1.0.6 /usr/lib/
 创建连接 libbz2.so.1.0 指向 /usr/lib/libbz2.so.1.0.6
 [root@xsmdmgr bsdiff4.3-linux]#ln -s ./libbz2.so.1.0.6  libbz2.so.1.0
 [root@xsmdmgr bsdiff4.3-linux]# ldconfig 

 shell  命令测试
  [root@xsmdmgr bsdiff4.3-linux]# ./bsdiff old.apk new.apk patch.apk
  [root@xsmdmgr bsdiff4.3-linux]# ll
-rwxrwxrwx 1 root root 3092113 02-21 10:44 old.apk
-rwxrwxrwx 1 root root 3400660 02-21 10:44 new.apk
-rwxrwxrwx 1 root root   14102 02-21 10:44 bsdiff 
-rwxrwxrwx 1 root root   11463 02-21 10:44 bspatch 
-rw-r--r-- 1 root root 1863695 02-21 16:18 patch.apk
成功

windows 下使用方式如下

 bsdiff.exe app1.apk app2.apk patch.apk

java调用
