android的apk該如解壓縮

今日將cyberlink的clink210.jar丟到android project去跑時，出現錯誤如下

好像是找不到clink.jar裡的org.cybergarage.upnp.ControlPoint？上google查了一些資料(1,2)，也試過該如何import clink210.jar才是正確，但到目前為止都是相同錯訊息。於是就想去看看輸出的apk是否有將clink210.jar包進去？

解apk的步驟如下：
1.下載apktool.jar & apktool-install-windows
2.解壓縮apktool-install-windows至任意資料匣，apktool.jar也放在裡頭
3.apktool d xxx.apk output

解apk的結果，看到下列目錄
-res
-smali
AndroidManifest.xml
apktool.yml

找了一下，並無我想看到的，是否clink210.jar有包在裡頭。
