在jar包下面找到兩個Ramdom類：
@aserver:~/rk3326_8.1_0320/frameworks/base/packages/SystemUI/libs$ jar -vtf jsch-0.1.56.jar | grep 'Random'
134 Sat Sep 03 18:41:46 CST 2016 com/jcraft/jsch/Random.class
774 Sat Sep 03 18:41:46 CST 2016 com/jcraft/jsch/jce/Random.class
加入引用還是一樣報錯：
import com.jcraft.jsch.jce.Random;
關鍵代碼：此代碼在android studio sdk25，27上編譯正常可以上傳，rk3288 7.1平臺也正常，就是在rk3326平臺報錯，更換jar包也一樣。相關jar包：http://gofile.me/4ZJ1m/E2uk9hzlw 密碼：123456

水平有限，找不出問題出在哪裏，請大家指點謝謝。
