Camera fails on Android 8.0

[michaeloki]

The plugin doesn't return a JSON object on Android 8.0 this prevents the app from getting the image uri and the error message in the failed callback shows that the issue is related to fileprovider i.e. file:// vs content://
See https://developer.android.com/reference/android/os/FileUriExposedException.html as a guide and permission issues.

It works fine for me on the emulator...

It fails on a real device.

I have created a pull request for this fix.

Using target sdk 27 on android 8, i get this error here

Using this call:

cordovaPlugin.camera.getPicture(onGetPhotoSuccess, onGetPhotoFailed, {
          correctOrientation: true,
          destinationType: Camera.DestinationType.FILE_URI,
          sourceType: type,
          saveToPhotoAlbum: true,
          targetWidth: 2048,
          targetHeight: 2048
        });

When setting saveToPhotoAlbum: false, the problem does not happen

That bug appears to be caused by this:

On android eight we don't have access to the destination file shown in the screenshot above

Use the forked version I created. This issue was reported but one of the maintainers relied on an emulator instead of testing it on a real device.

It appears that replacing WRITE_EXTERNAL_STORAGE with READ_EXTERNAL_STORAGE inside CameraLauncher fixes the problem.
