问题描述
我在无障碍服务工作。我需要得到使用辅助服务的应用程序名称。我研究的辅助服务在Android的网站的开发者文档。但目前还没有得到关于使用辅助应用程序名称提及。

推荐答案
您无法获得应用程序的应用程序名。至少不可靠。该应用程序读取的字符串的东西之类的标题标题栏或应用程序图标下方的字符串。它从来没有真正直接要求它连接到应用程序的标题的框架。
You can't get the "app name" of the application. At least not reliably. The strings that the app reads out are things like the title of the Title Bar, or the string underneath the apps icon. It never actually directly asks the framework for the title of the app it is attached to.
您这样做，不过，可以访问应用程序包。
You do, however, have access to the application package.
someAccessibilityNodeInfo.getPackageName();
这唯一标识一个给定的AccessibilityNodeInfo被发送应用程序。
This uniquely identifies the application that a given AccessibilityNodeInfo was sent from.
您还可以考虑使用这样的：
You could also consider using this:
someAccessibilityService.getRootInActiveWindow();
和抓取下来寻找一个标题栏视图层次结构。
And crawl down the view hierarchy looking for a title bar.
