I want to ‘open with’ my application when user wants to open pdf, so I added intent filters in manifest xml and created +native-intent.ts to get pdf path in FileProvider. It works when opening from ‘My Files’ which is default native file manager in Android.

But When I open the file from other apps, like Kakaotalk or Slack, and copy that content:// file into file:// which is in cache directory, the error below occurs.

I tried to make native module to call currentActivity.grantUriPermission(currentActivity.packageName, uri, Intent.FLAG_GRANT_READ_URI_PERMISSION), but it did not work (java.lang.SecurityException: UID 10874 does not have permission to content)

code where error occured

async function copySharedPathToUri(contentUri: string) {
  const destinationUri = FileSystem.cacheDirectory + "tempFile";
  await FileSystem.copyAsync({
    from: contentUri,
    to: destinationUri,
  });
  return destinationUri;
}

error

Error uploading file: [Error: Call to function 'ExponentFileSystem.copyAsync' has been rejected.
→ Caused by: java.lang.SecurityException: Permission Denial: reading androidx.core.content.FileProvider uri content://com.kakao.talk.FileProvider/external_files/emulated/0/Android/data/com.kakao.talk/contents/MTg=/2412.10468v1.pdf from pid=25200, uid=10858 requires the provider be exported, or grantUriPermission()]

+native-intent.ts

export function redirectSystemPath({
  path,
  initial,
}: {
  path: string;
  initial: string;
}) {
  try {
    console.log("redirectSystemPath", path, initial);
    return `/?sharedPath=${encodeURIComponent(path)}`;
  } catch {
    return "/";
  }
}
