Expo: Invalid Filesystem URI

Created on 3 Oct 2017 · 3Comments · Source: expo/expo

Hello, i'm trying download a file using:

FileSystem.createDownloadResumable("http://remote-uri.com", `${FileSystem.documentDirectory}my_file.ext`)

In IOS it works very well, but in android i got this error:

 Invalid Filesystem URI 'file:///data/user/0/host.exp.exponent/files/ExperienceData/%2540my_user%252Fmy-react-native-app/my_file.ext', make sure it's in the app's scope.

What can i do?

Environment:

"expo": "^20.0.0",
"react": "16.0.0-alpha.12",
"react-native": "https://github.com/expo/react-native/archive/sdk-20.0.0.tar.gz",

I have a discussion here too

I found a solution. I create a folder inside document directory and after it works well.

ensureFolderExists () {
    const path = `${FileSystem.documentDirectory}MyFolder`
    return FileSystem.getInfoAsync(path).then(({exists}) => {
      if (!exists) {
        return FileSystem.makeDirectoryAsync(path)
      } else {
        return Promise.resolve(true)
      }
    })
  }

ensureFolderExists().then(() => {
  FileSystem.createDownloadResumable("http://remote-uri.com", `${FileSystem.documentDirectory}MyFolder/my_file.ext`).downloadAsync()
})

Any update here? From my debugging it seems like on android, you can access child directories of documentDirectory and cacheDirectory, but not either directory itself.

Example:
FileSystem.readDirectoryAsync(FileSystem.documentDirectory) // fails with 'invalid uri'

FileSystem.readDirectoryAsync(FileSystem.documentDirectory + 'cats/') // success

I just tested this at the root and it works, and I think this may be related to https://github.com/expo/expo/issues/739 so closing for now. Please comment if you face this again!
