HTC EVO 3D Wallpaper Picker

Supported file formats: .jps, .mpo, .jpg, .png

FAQ:
- How do I set up this 3D wallpaper?

- What kind of images can be used?
Usually 3D images are stored as .jps or .mpo file.
When picking a background, make sure the image is Side-by-Side 3D and you select 'Use 3D'

- A black wallpaper is shown with a red exception in the center. What is it?

- Why do I have to set a live wallpaper?
The Live Wallpaper is a container for the selected 3D image you choose from the gallery. By using a Live Wallpaper container, the 3D mode can be enabled and disabled automatically.

- Do I need root access on my phone to get this app up and running?
For HTC Sense ROMs, root access is not needed. Non-sense ROMs however need root to enable the 3D display.

- Where can I post my findings or questions?
In the Play Store comments, but preferably here:
http://forum.xda-developers.com/showthread.php?t=1894753

- Where can I find 3D wallpapers?
Install Phereo 3D Photo, which will allow you to view and store a lot of 3D images. https://play.google.com/store/apps/details?id=com.phereo

- Your app is requesting su permissions. Why?
Setting the 3D mode using the HTC Sense framework failed, so a different way (fallback method) is used. (Framework confirmed working on Sense 3.6 and Sense 4.0

- Are there any known bugs?
1. If a 3D boot animation is installed, the last few seconds of the boot animation will be in 2D interlaced instead of 3D, as Android is already drawing the wallpaper. Because it's invisible, the script to disable 3D is called...
2. Sometimes the screen blacks out when switching from 3D to 2D view. Known fixes; A. Wait a few seconds to let it restore the backlight. B. Open the camera with the dedicated camera button, switch to 3D and after a few seconds back to 2D with the dedicated 2D-3D switch.
3. After setting the Live Wallpaper for the first time, the screen might not switch to 3D. Turn off the screen or open any app and switch back to the homescreen. It should now be enabled.

Thanks to Meine Toonen for the MPO decoding co-op
and jmztaylor for the 3D switch idea.
