ImageViewer has a couple of bugs that I don't have the knowledge of how to fix.

• - Double tapping to reset the transform and the close button works only while interacting with the Rotate- Zoom- and RotateGestures.
• - Rotation gesture often wraps around, resulting in a rotation > 180°, instead of taking the shortest path.
• - A bunch of TODO comments and confusion regarding removed/renamed/deprecated features

Tested using Android preview, Fuse 0.26.0 (7741)

Hi!

When I export the Storage Example to my Android show this log and the app not open..

The GithubOAuth example uses OAuth2's authorization code grant.
This is fine if you can delegate the authorization to a server you own and store the client secret there, but this isn't the case here. The README instructs users to paste their client secret into the app. This is a very bad idea™, as these can very easily be extracted from the exported package.

To be fair, there is a security warning in the README, but "Note:" is not how you tell people about fundamental security flaws.

There does exist another OAuth flow, implicit grant, which doesn't require a client secret. GitHub does not support this, however.

We should either provide some basic server code, or switch to a different provider for this example.

I updated it to expose its service as a JS API, but it crashes on Android.

When fixed, please add it back to the README index.

Please see here:
https://github.com/fusetools/fuse-samples/tree/master/Samples/OSUI

If possible this would highlight how to override the default behaviours. Such as:

• Disabling swiping to toggle the menu
• Disabling dragging of menu panel when its active
• Applying alternative triggers

These questions come up a lot on Slack so thought I would post the request here.

Hi,

I am trying to run NativeFacebookLogin example on both iOS and Android. It is working on iOS but getting below error in Android.

Any idea how I can fix it?

The below code doesn't appear to be used in the example:

            exports.selectHour = function(args) {
                exports.hoursX.value = args.value%12
                exports.hoursY.value = Math.floor(args.value/12)
            }

            exports.selectMinute = function(args) {
                exports.minutes.value = args.value
            }

https://github.com/fusetools/fuse-samples/blob/master/Samples/Controls/Circular/MainView.ux

https://github.com/fusetools/fuse-samples/tree/master/Samples/FacebookLogin

The example appears to use a deprecated approach for including JS modules, causing it to fail with a misleading error message.

I think the fix amounts to:

• Remove from MainView.ux
• Add **.js:Bundle to the includes in the .unoproj

The readme no longer matches:
