Open file downloaded within React-Native app with another app - react-native

Question

I am trying to open files (images, pdfs, videos, etc) downloaded with my React-Native app from my server.
So I'm using RNFetchBlob to download the file then I'm doing the following depending if it's an iOS or Android device:
openFile = (item, path) => {
if (Platform.OS === 'ios') {
RNFetchBlob.ios.previewDocument(path)
} else {
// I've tried setting a real mimetype instead of / but it still doesn't work
RNFetchBlob.android.actionViewIntent(path, '/')
}
}
On iOS it works as expected but nothing happens on Android even though I have apps that can read images, pdfs or videos on the device I'm testing on.
Any ideas why this doesn't work or how I could make the same thing with another library ?

Answer 1

Found out the reason for this, it's a know bug of the library and has a PR waiting to be merged (no timeframe from the repo owner).
Here is the link to the PR: https://github.com/joltup/rn-fetch-blob/pull/317
So basically this needs to be added to line 122-123 of file android/src/main/java/com/RNFetchBlob/RNFetchBlob.java:
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
If above is not working do to the below step:
overwrite the 121 line in android/src/main/java/com/RNFetchBlob/RNFetchBlob.java:
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // 121 line
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); // 122 line
