Fix for FILEURIEXPOSEDEXCEPTION with cordova-plugin-camera on Android N
Karen Tran February 14, 2017
MobileFirst_Foundation Cordova cordova_plugin_camera Android_N
Starting in Android Nougat, file URIs are restricted to the scope of the same app. This access restriction causes a FileUriExposedException when you use the Cordova camera plugin with the Android platform. When the device’s camera app passes the file URI of a photo to the Cordova camera plugin, the plugin is not allowed to access the file URI. When the plugin tries to access the URI, the exception will be thrown and the app will crash.
Cordova has created a solution which utilizes the Android support libraries’ FileProvider class to create a custom URI for photos in place of file URI. Cordova’s solution fixes the issue, however, it requires adding the Android Support v4 library whenever the Cordova camera plugin is installed.
The solution has been backported to three versions of MobileFirst Foundation but requires additional setup from users who uses the Cordova camera plugin. Users who do not use the Cordova camera plugin do not need to do anything.
