Android RNFS.downloadFile only store file to root access directory

[adamnator92]

Environment

react: ^16.3.1 react-native: ^0.56.0 react-native-fs: ^2.11.18

Current behaviour

on android set the download file path toRNFS.DocumentDirectoryPath, but unfortunately it will only store to android root access directory /data/user/0/com.[appname]/files.

const ret = RNFS.downloadFile({
    fromUrl: url,
    toFile: RNFS.DocumentDirectoryPath + file.jpg,
});

any way i can save the downloaded file to public directory allow user to access from gallery?

• CachesDirectoryPath (String) The absolute path to the caches directory
• ExternalCachesDirectoryPath (String) The absolute path to the external caches directory (android only)
• DocumentDirectoryPath (String) The absolute path to the document directory
• TemporaryDirectoryPath (String) The absolute path to the temporary directory (falls back to Caching-Directory on Android)
