Answer 1

我有完全相同的错误跟踪(从 InflateException 到 FileNotFoundException: res/color/primary_text_light.xml)并像这样解决它:

1. 我比较了res/drawable-hdpi和res/drawable的内容
2. 我将所有丢失的文件从 res/drawable-hdpi 复制到 res/drawable

所以我会说:确保您的每个 res/drawable* 文件夹包含相同数量的图像，具有相同的文件名。

注意:这很奇怪，因为我从未使用或添加任何名为 primary_text_light.xml 的文件，所以我不知道为什么 Android 首先会提示它。无论如何，我希望这会有所帮助:-)
