FileUriExposedException on Android 7+

So we have recently seen that Google will block updates from apps with `targetSdk` < 26. Our apps currently use SDK 23, which works fine. Since then, we were trying to update to Target SDK 26 and comply with Google's definition.

However this plugin does not work with SDK 24+, since it requires you to use `content://` addresses instead of `file:///`. I have tried to find some replacement and updated the plugin to version 6.0.1, but to no avail.

We are also using `@ionic-native/file`, which basically just wraps `cordova-plugin-file` and adds type definitions.

Whenever we try to copy a file to `cordova.file.externalApplicationStorageDirectory` the app crashes, closes, due to a `FileUriExposedException` from `ClipData.Item.getUri()`.

Is there any solution to this?

Reproduce the crash on Android 7+ with targetSdk 26 while copying a file to cordova.file.externalApplicationStorageDirectory, then inspect the plugin's copy operation and its Android URI handling. Done means the same copy completes without FileUriExposedException and remains compatible with the cordova-plugin-file 6.0.1 context.
