[Android] Sharing data uri silently fails without WRITE_EXTERNAL_STORAGE

Tried with RN 0.44, Android M & N.

I cannot get the url option to work to share an image. I’m using a data URI of an image. I’ve also tried the sample code in this repo.

• If I do Share.open and pick:
  • Gmail url is ignored. (subject and message work)
  • “Upload to Photos” I get a toast saying “Error, could not load media”
  • “Save to Drive” I get a toast saying “Upload was unsuccessful, request contained no data”

It seems like the url is dropped on the way. I’m going to see if I can step through the code in Android Studio to make sure the URL gets all the way to the intent.

(FWIW, this works great in iOS)

Thank you for sharing, tough I solved this by setting permissiosAndroid and writing the file I wanted on a external directory since its the only accepted path on all android apps.

How to write the file on an external directory? I am using react-native-fetch-blob to write the file,

addAndroidDownloads : {
            useDownloadManager : true, // <-- this is the only thing required
            // Optional, override notification setting (default to true)
            notification : true,
            // Optional, but recommended since android DownloadManager will fail when
            // the url does not contains a file extension, by default the mime type will be text/plain
            title:`xxx.pdf`,
            mime : 'application/pdf',
            description : 'File downloaded by download manager.',
            mediaScannable : true,
            path: RNFetchBlob.fs.dirs.DownloadDir+`xxx.pdf`           
          }

and share the pdf as

Share.share({
      title: 'xxx',
      url: `${path}`
      }
    )

Gmail still ingnore the url, can anyone help this?
