Update: July 30th: Alina has released version 3.0.2, which should fix the issue of exporting conversations to the Android Documents folder, and which provides the ability to drag a visble HUD on your screen to reposition it.
Lumiya, the go-to Second Life / Open Sim client for Android has been extensively updated, with version 3.0 released on Wednesday, July 27th, and a further 3.0.1 release with additional fixes, options and requests, hitting Google Play on Thursday, July 28th.
For those unfamiliar with Lumiya, it is an extensive Android client offering all the essential functionality found in the viewer: ability to chat, IM, carry out group functions, manipulate inventory and outfits, manage transactions, interact with objects (including viewing & editing scripts, permissions allowing), teleport to places, view the map, and so on. And, for those who wish a more immersive experience on their android device (providing it has the processing power), Lumiya provides a real-time scene rendering capability, allowing you to see the world and other avatars, touch objects, operate your camera, walk, fly, and so on.
With version 3, Alina Lyvette, Lumiya’s developer, has completely overhauled the client, and while there are still some little niggles, the result is once again quite astonishing.
The Interface
For regular Lumiya users the most obvious change is to the client’s UI. This has been completely re-worked top-to-bottom, offering a far more intuitive, mobile device style approach, incorporating things like pinch / zoom screen actions, sliding menus, and a much cleaner look and feel. By default, Lumiya now launches in its blue / white appearance, with the blue / black an option, alongside a new pink appearance option. In addition, the 3D mode has been overhaul to make use of mobile device gestures such as pinch / zoom and drag, and the buttons have been revised and improved to give the in-world view a much cleaner look.
The log-in screen retains much of the “old” look, with short cuts to select the details of any account previously used to log-in to SL with Lumiya & auto-populate the user name / password fields, and to access the client’s settings, together with a drop-down to access the grid selector (where you can also add new grids) or to show your password in text when logging-in.

Once logged-in, the UI is in conversation mode, with local chat open the conversation screen opens. This has two points of particular interest: the first is the Android menu icon in the top left corner of the screen (see above), which replaces the Lumiya icon. tapping this will display the Lumiya menu (which can also be displayed with a simple left-to-right swipe of the screen).
The second is that profile icons are now displayed in the chat and contact tabs throughout Lumiya – in the image above, for example, the profile picture for Preiddeu Annwn is displayed in the image above.

The new UI design does mean there are some significant changes to where some options might now be found which will take users a little time to get used to; however many of these changes make Lumiya feel more “viewer like” in its approach. For example, group options have all now been brought together under the group profile display, rather than various menu / drop-down options. What’s more, they now allow group roles to be created and assigned, and member’s abilities edited.
So, accessing a group profile is now a matter of clicking Group tab in the Chat window, then tapping the required group and tapping the Profile icon in the top right of the group message display. The group’s profile is displayed in a layout similar to that of many TPVs, with individual tabs accessing various options. Thus, people can be invited into the group from the Profile tab (providing you have the ability to invite new members); roles can be added / edited from the Roles tab; and members can be operated on from the Members tab.

Given the extend of changes to the IU, the easiest way to familiarise yourself with them is to spend time using Lumiya. Keep an eye out for changing icons, and things like the Android three vertical dots icon (generally top right of the Lumiya window), indicating when further options are available within in given screen.
The 3D View
The other very noticeable change to Lumiya for existing users is the 3D world view (Lumiya menu > 3D View). As noted above, this now uses Android pinch and drag gestures to manipulated the camera by default, leaving the (redesigned) on-screen buttons for avatar movement and flight. However, for those who prefer to toggle the movement buttons between avatar and camera movement, it can be reinstated via Lumiya menu > Settings > 3D View, and then checking Show Camera Button. note that even with the camera button enabled, you can still use Android gestures to manipulate the camera as well. For ease of reference, screen captures here show the camera button.

The two overlay buttons – Chat and Outfit – do just that: overlay the in-world view with your chat options or Outfit folder, allowing you to converse or change outfit, as per previous versions of Lumiya. However, the two buttons which are likely to be of particular interest in the new 3D view are the HUD button (lower left) and the Target Picker (top right of the Lumiya window).
