[APP][4.0+] 500 Firepaper v3.00

500 Firepaper provides a live wallpaper and a daydream showing you the latest images from /r/EarthPorn throughout the day.

You never need to look at that boring old wallpaper again, or search for hours for a nice new one. This app will show you quality photographs from all over the world - different ones each day!

NOTICE: This app switched from using the 500px API to showing images from Reddit's /r/EarthPorn sub, as 500px is shutting down their API. Please read the statement on my G+ page - https://plus.google.com/+Chainfire/posts/W52tb4kp8zN

Configurable options include the refresh interval, brightness of the images, oversaturation, and blurring.

Please note that high resolution imagery and animation takes quite a bit of memory, so obviously this app is aimed at high-end devices.

If you are a Muzei user, 500 Firepaper also presents itself as an art source to Muzei.

FAQ

What does buying Pro get me?
I've already made all the features available to you for free. Supporting my developments is optional, but certainly appreciated.

Why is there no save feature ?
Not allowed per API terms

Three finger tap to go to the next image doesn't seem to work, what now ?
On some devices (like the HTC One) you need to put down your fingers one-by-one.

Why does this use so much RAM ?
High-resolution imagery takes a lot of memory in uncompressed form, and multiple buffers are required. But fear not, should your device need the memory while the wallpaper/daydream is not visible, the memory occupied by the app will automagically be released and repurposed.

Can the cached images be put somewhere else, like on my sd card ?
No, they cannot.

Do you want a balloon ?
No, but thanks for asking.


Notices

Why ? (you can skip this if not interested)

So this really isn't anything special and probably nobody cares about it. But here it is anyway.

I actually started writing something a little bit like this years ago (which was called Firepaper) which had loads of advanced options, but due to Android 2.x and the constant fighting with memory limitations, I never released anything. Then past February I thought about doing something with 500px, and wrote a lot of the code, but for some reason never finished it. This weekend I had some time to spare and didn't feel like working on any of my usual apps, and I was annoyed with the Nexus 5 wallpaper, so I finished this up (this is something I actually want for my own phone).

There's other live wallpapers and daydreams that do similar things. But due to the nature of background syncing, caching and transferring images I didn't really feel like trusting somebody else to get that right, and not drain my battery when I need it most or rake up the data charges. Not that I'm convinced I did it right, but it works for me so far
