调用该方法出现如下错误：
org.openqa.selenium.WebDriverException: An unknown server-side error occurred while processing the command
望知道的人吼一嗓子
请详细描述，发 bug 也这么发么？
#1 楼 @lihuazhang
ecilpse 中用 java 调用 appiumDriver 的这个方法运行然后报错。
appium 控制台输出如下：
debug: Appium request initiated at /wd/hub/session/e64576a0-d47b-449b-909a-5ba62
be6ed92/appium/app/strings

你的 apk 不存在本地，device 上也没有，就报错了。
不是获得我启动的那个 apk 么？

这两个是说，你不是从本地重新安装 apk 的，你的 device 里面已经装好了。那你确认下，你的 device 里面装了 weibopro 没？
#8 楼 @lihuazhang
装了，且已经启动成功进入主界面。

#10 楼 @lihuazhang
adb shell am start -n com.sina.weibopro/.ui.HomeActivity
启动成功
分析 log 得知：
这个方法是获得 appium 事先放在手机端的临时目录里的 strings.json 文件里的数据，这个文件会在 case 初始化阶段在 PC 上解析你提供的 app 里的 strings.xml 文件，然后 push 到手机临时目录中的。所以不提供 app 路径是无法调用该方法的。
