我正在尝试在模拟器上启动 android 应用程序。.apk 文件对我来说似乎很好，因为我可以在 emulator 上手动打开应用程序，但它无法通过 appium 打开。
下面是我的日志

所需的功能如下：`
File classpathRoot = new File(System.getProperty("user.home"));
File appDir = new File(classpathRoot,"Desktop/");
File app = new File(appDir.getCanonicalPath(),"AQ.apk");
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("deviceName","Android Emulator");
capabilities.setCapability("app",app.getAbsolutePath());
capabilities.setCapability("appActivity",".MainActivity");
capabilities.setCapability("fullReset",true);
` 我正在尝试测试一个反应原生应用程序，我已经生成了一个用于测试 android 应用程序的 .apk 文件。寻求建议/指导/帮助，谢谢
