AndroidStudio报错
W/System.err: java.lang.IllegalArgumentException: Failed to find configured root that contains /storage/emulated/0/.../Cache/P_20201118144205.jpg
如图：

解决方案
找到file_provider_paths.xml（每个项目的该xml的名字可能会有些许不同），在里面增加

 	<external-path
        name="app_provider_path_A10"
        path="." />

如果已经有了，就把path的值改为.或者/
