我正在尝试获取一个可以在Android手机上运行的应用程序。该应用程序在我的Macbook上运行良好。我只使用了预先安装了python或kivy的模块，但是仍然在加载图标出现在kivy启动器上后，应用立即崩溃。因此，我进行了一些挖掘，发现可以通过解锁手机上的开发人员选项并使用logcat来检查日志，但问题是，logcat吐出了很多信息供我解析。
有没有一种方法可以过滤logcat来专门为Kivy Launcher提取日志？我已经检查过所有内容，而且所有人都说您可以按应用名称过滤它，但是我尝试过
adb logcat“ application_or_tag_name：”“ ：S”
例如： adb logcat“ Kivy_Launcher：”“ ：S” adb logcat“ kivy_launcher：”“ ：S” adb logcat“ Kivy Launcher：”“ ：S”
但是它们似乎都不起作用。我已阅读以下链接：
https://logmatic.io/blog/a-how-to-guide-to-debugging-with-android-logcat/ https://developer.android.com/studio/command-line/logcat
我能够通过Android Studio获取一些日志，但是不确定这些日志是否是我为启动该程序而必须创建的“新应用”的日志，或者实际上是否是我手机上的日志？我启动了kivy启动器。这些是：
