Downloading a file doesn't work on Android 7.
Trying to open a file with RNFetchBlob.android.actionViewIntent from react-native-fetch-blob we get:

We get similar issues when trying to send a file to another application with Share.open form react-native-share:

----------------------------------------------------
We are now following the Android 7.0 Behavior Changes instructions about file sharing using a content:// URI with temporary access permission granted through a FileProvider.
We needed to implement our own RNFileSharing native module for this purpose and also to properly handle the callback for deleting the downloaded file after the Send or View activity has been completed. Indeed:
- RNShareModule#open resolves the promise after having opened the chooser dialog but not after having acually sent the file to the other application.
- RNFetchBlob#actionViewIntent uses a LifecycleEventListener that is working on Android 6 but not on Android 7: the onHostResume method is called right away after having opened the other application, not waiting until it has been closed.
Using ReactContext#startActivityForResult with an ActivityEventListener without setting the Intent#FLAG_ACTIVITY_NEW_TASK on the intent to start solves it.
Note that this also solves:
