老师您好，我这边运行Appium提示UiAutomator exited unexpectedly with code 255, signal null。场景是设备重启，然后要等重启完毕后再进行操作。脚本没有变化，之前运行并没有出现这个问题。

表面现象 去看有没有appiumbootstrap.jar，在/data/local/tmp下AppiumBootstrap.jar
如果没有，在appium的node_module目录下面的appium-android-bootstrap\bootstrap\bin找到AppiumBootstrap.jar，然后复制到/data/local/tmp就可00
