Subject [jira] [Commented] (CB-11592) Crashes due to android 7.0 "file://" Handling "android.os.FileUriExposedException"

Christoph Brosdau commented on CB-11592:
----------------------------------------

As mentioned above - I can confirm that is happens in Camera (somehwere, a "file" URI seems
to be exposed), the complete File Plugin is based on the Idea of returning file:// URLs (mostly),
which should be avoided. inAppBrowser is not really a bug, I think - if i give it a file://
URI (e.g. for opening a PDF), then it will crash. But thats due to the fact, that I give it
a file:// URI for external purposes, and thats forbidden. I think, in Camera, there is a Bug.
In File Plugin, there should be a more general approach - how to deal with File URIs in future
Versions (implement a FileProvider, Content URI, Temporary Permissions etc - probably). But
thats really a huge amount of work to think of. (For our specific needs, I created a new local
Plugin, which handles PDF Download (still works with Cordova), but the opening (until 6.0
 simply via inAppBrowser) is now completely different (it uses Changes in Manifest, a local
FileProvider, Share Intents with temporary Permissions, as outlined by Google). So for sure
its possible, but far more complicated than before - at least in our case.
If the behaviour of inAppBrowser is really a bug - depends on your point of View, I would
say.

> Android 7.0 removes the "file://" Protocol or to be more precise, removes the possibility
to share URIs with "file://" Protocol outside the Scope of the own App. If some Code tries
this, the result is "android.os.FileUriExposedException".
> This affects a variety of Plugins:
> - inAppBrowser: opening a file:// URI (e.g. to show a downloaded PDF) crasehs the app,

> - Camera crashes immediately: opening a cached File by "ClipData.Item.getUri()"
> - possible a couple of the File Plugin Methods
