rk3326 android 8.1 上傳sftp時候jsch類報錯（已解決）

https://blog.csdn.net/yhm2046/article/details/105034357

前兩天的問題已經解決，做個記錄

參考：https://bbs.csdn.net/topics/396196538

https://www.jianshu.com/p/b333f3718373 //Android代碼混淆

https://blog.csdn.net/forlong401/article/details/23539123  //ProGuard的作用、使用及bug分析

https://blog.csdn.net/ooo4561213/article/details/7287557 //android 混淆器的使用 proguard.flags

https://blog.csdn.net/zhelong111/article/details/84507657?depth_1-utm_source=distribute.pc_relevant.none-task&utm_source=distribute.pc_relevant.none-task  //Android不混淆第三方jar包

https://blog.csdn.net/wusj3/article/details/93460996  //解決Android 8.0及以上系統接收不到廣播的問題

原因：

1.android8.1默認開啓了混淆，導致找不到第三方jar包內的方法

2.jsch類網絡連接在wifi連接時候會有不流暢問題，加入sleep和for循環解決

原因1解決辦法：

修改\frameworks\base\packages\SystemUI\proguard.flags：加入紅色代碼
