I place a "strings.xml" file in the StreamingAssets folder because I want to load some parameters from it. But I failed to load this .xml file. I tried to load this file by System.IO, the path of it is Application.streamingAssetsPath + "/XML/strings.xml", and failed. Also, I tried to load this file by WWW, the path of it is "file://"+Application.streamingAssetsPath + "/XML/strings.xml", and failed. Also, I notice that the WWW is already obsolete in Unity2018.3. So what's the best way to load this config file in Android(API>=24)?
