Record activity: Starting multiple records results in an error.

[DeepakMuddha]

Like the older build we’re testing on the XO-1.75, you can start multiple records. The first record locks the camera and the subsequent records display a white screen. However unlike in the XO-1.75, quitting the first one and then the second one does not cause the second record to freeze.

To reproduce:

1.Open record activity.
2.Now go to home screen keeping the 1st record activity opened
3.Now open the record activity again for the 2nd time.

Result: Camera appears fine in 1st record and a white screen appears in the second record

I've written some patches to Sugar [1, 2] that implement a maximum_instances limit settable in activity.info. We need to add:

maximum_instances = 1

to Record.activity/activity/activity.info

However, these patches, while they are being pulled into AU 1B, are not yet upstreamed. Hopefully they will land in Sugar 102.

As this is fixed in AU image, I remove the AU1B keyword, keep it open until inclusion upstream.

​http://wiki.sugarlabs.org/go/Features/LaunchLimits landed in Sugar 100.

And a merge request was made to the Record activity. Until that merge lands, [3] is available.
