Wow! Cool! 38-50fps with 100 Pandas on my Fly IQ441 (Android 4.0.4)
11thPenguin: what does your build support so far? If you’re willing to share the code, I can see if I can integrate useful bits into my own implementation.
All the 3rd party libraries I checked seem to have Android versions or can be compiled for it without too much effort.
When did mobiles get so powerful?
Anyway.
FMOD has android version: fmod.org/fmod-downloads.html
OpenAL has been compiled by some already: pielot.org/2010/12/14/openal-on-android/
Miles has Anodroid version: radgametools.com/msssdk.htm
Couldn’t find anything for ODE physics.
Bullet can be compiled: bulletphysics.org/Bullet/phpBB3/ … f=9&t=4158
PhysX 3.1 seems to support Android.
First page of libRocket GUI library shows an Android game using it. librocket.com/
If we don’t have a stripped down Panda support on Android with less features than Panda in my opinion will be a very attractive option for Android game developers.
100 pandas on Samsung galaxy s3: 40-60fps
(android 4.1.2)
For audio, we can simply implement OpenSL ES, which is supported since Android 2.3 and seems powerful enough by itself. It supports decoding audio as well, which is something that OpenAL does not do.
Many of the image loading and video decoding libraries don’t need to be ported, as we can use Android’s own decoding implementations for this. For instance, I recently finished implementing Android’s bitmap loader, which replaces the need for libpng and libjpeg.
We can also replace ffmpeg with Android’s own video decoder, OpenCV with Android’s Camera class, freetype with Android’s font loading mechanisms, etc.
Compiling the remaining libraries for Android should be relatively easy.
For anyone who wants to try it out, I’ve checked my stuff into CVS. Here’s an apk showing a JPEG-textured Panda loaded from Android’s asset storage:
rdb.name/PandaActivity-debug.apk
Requires arm architecture, Android 2.3+. Runs at around 25 FPS on my Samsung Galaxy Ace when animating, 45 when not.
Compiled using:
export NDK_ROOT=c:\cygwin\home\rdb\android-ndk-r8d
mkdir built
cp -R models built/assets
python makepanda/makepanda.py --everything --target=android --arch=arm --no-python --no-pandatool --no-sse2 --no-neon --optimize 4
# Replace -t 1 with the desired target from "android list target"
android.bat update project -t 1 -p built
(cd built && ant debug && ant installd)No thirdparty packages needed.
(If you have an ARMv7a device, you can use --arch=armv7a for a better build. If you have an x86 emulator, use --arch=x86)
Around 40 when animating and 60 when not.
BTW, was happy to see panda’s default font and gui on my phone 
Is there any way to debug why none of these would run on my tablet?
NenaMark2 runs on it at 16.9fps, so I think Panda should as well.
What are the specs of your tablet? Android version, CPU type, architecture, GPU?
Android 4.0.3, the rest is a bit of a mystery. The cpu could be either Action solution 1 Ghz or Cortex A8 Allwinner A13 1 GHz, gpu ‘Integrated Graphics 400 MHz’ (could be Mali 400 MP).
There are no specs in the manual, on the producers site there are 3 models with more or less the same name.
It’s the cheapest I could get (~70$)
One downside with using OS specific libraries I can think of is having different code which needs separate maintaining. Do you think it’s worth it?
Good to hear.
In most cases, the code is simple and small enough. I think that having to maintain several separate thirdparty libraries (libjpeg, libpng, especially ffmpeg) will cost much more effort than maintaining this sliver of code I have that converts an Android Bitmap object into a Panda PNMImage, etc. If the OS provides all of these features for us, I don’t see why we wouldn’t take advantage of them.
wezu, can you give a logfile? You can retrieve the logfiles on your computer using “adb logcat”. That said, that build of mine may have debug logging disabled, but maybe there’s a useful error message in there.
Alternatively, you can use an app such as Log Collector on your device to acquire and send the log file.
I think this part of the log is about panda:

@preusser: I meant having to maintain Android builds of that thirdparty package, ie, having to go through the effort of rebuilding it for four different architectures (often involving many fixes to the build system or source) every time the version changes.
Also, consider that the Panda Android build has to remain small. Right now, the apk I built is a little over 5 MB, but after adding a few thirdparty packages it’s easy to push that over the application limit.
@wezu: that looks like a mips system, instead of conventional arm. That’s just a matter of enabling a build option. I’ll include mips next time I upload a build, or perhaps I’ll make a separate build so that you can test it on mips.
Could you perhaps confirm that it is in fact a mips system, using an app like Dalvik Explorer? You should be able to find this information under “Build Details” > “CPU ABI” and also the processor stuff under “Device Details”.
It’s ‘mips’. I’m off to google what ‘mips’ is.

javax.obexIf the size of the app will get much bigger then a separate build for this exotic system seams a good idea.
It’s a CPU architecture, just like i386, amd64, ppc and arm. They are mostly incompatible with each other, so binaries built for one instruction set will not run on another (with the exception of i386, which is a subset of amd64). Android supports four instruction sets at the moment: arm, arm-v7a, mips, and x86, so we will be building for all four in order to support every Android device.
Oh, okay then, those are good reasons.
I guess we can update the Features page of the website when Android version is done to make it clear what the Android version uses, as well as the manual pages.
The resulting feature set will be more or less the same, so that may not be necessary. There may be some differences in the supported audio formats and video formats, but this also works in our favour - we also get support for webp and webm formats out of the box, for instance.
