@fenfenzhong 有没有统计游戏 FPS 的方法

这个版本是不是不能获取游戏的 FPS，有没有什么好办法可以获取到游戏的 FPS？

有什么方法可以获取游戏的 FPS 吗？

怎么通过这些信息来分析问题呢？
比如 ANR、性能问题？
有没有一些好的经验可以分享？

@kasi 有没有私聊的方式？

@kasi 卡斯是华为的？

@xuxu 多谢！

File app = new File(appDir, "ContactManager.apk");

app 设置是必须的吗？如果测试已经安装好的应用？

Sample-code 中 “android-simple”，我注掉：

// desired.app = require("./helpers/apps").androidApiDemos;

提示：

> info: [debug] Responding to client with error: {"status":33,"value":{"message":"A new session could not be created. (Original error: No app set; either start appium with --app or pass in an 'app' value in desired capabilities, or set androidPackage to launch pre-existing app on device)","origValue":"No app set; either start appium with --app or pass in an 'app' value in desired capabilities, or set androidPackage to launch pre-existing app on device"},"sessionId":null}

@test_skp @xuxu 有没有参考的脚本，谢谢

会提示错误：

注掉不行的，试过了

desired_caps['app'] = PATH('ContactManager.apk')

是必须的吗？

如果不需要安装，直接运行机器里已经安装好的应用，要怎么处理？

desired_caps['app'] = PATH('C:\Users\Stephen\Desktop\ContactManager.apk')
是必须的吗？
