So I developed a small 3d game on Android 1.6 with JPCT, the free 3d game engine Android version. It seems the frame rate is really low on emulator(5 frames per second).... Did I miss something to speed up the emulator or it is normal, I should test the game with real device?

I used the NDK and OpenGL ES 2.0 to display a frame as a texture on a GL_TRIANGLE_STRIP. This was done on a HTC Desire, same hardware as Nexus One. I tried to load multiple GL_RGBA textures and switch between the textures, because the normal fill rate with a single texture was disappointingly low:

I think even 30.32 fps RGBA is still too slow.
So is this the way to go to achieve the fastest 2D frame rate (with same quality)?
Any suggestions to speed it up?
Here is the relevant code, it is based on the hello-gl2 NDK example:

I am a n00b to all things android. But I'm up to speed on rooting. What I am not up to speed on is the frame rate.I want to keep this phone so bad because I love it. But you know what the one thing the iPhone has over us? Smooth transitions and stuff. I know that has to do with fps.I figure if it has been done before it can be done again. Has fps ever been lifted before? Or are we spitting in one hand and wishing in another?
View 4 Replies View RelatedI am trying to get a quite simple openGL ES 1 program run a smooth solid 60fps on a couple devices out there, and I get stuck on HTC desire. The phone itself is quick, snappy, powerful, and overall a breeze to use ; however, I can't seem to display anything fullscreen at 60fps with OpenGL. After getting stuck for a long time with my app, I decided to make a test app with code right out the sample code from the documentation.Here is what I am doing. Simple initialization code with GLSurfaceView. I have three versions of onDrawFrame, all dead simple. One is empty. One contains only glClear. One contains just enough state to only draw a fullscreen quad. Trace times before, and after. There is no view other than my GLSurfaceView in my program. I can't explain the times I get.In all cases, the onDrawFrame function itself always finishes under 2ms. But very often, onDrawFrame does not get called again before 30~40ms, dropping my frame rate all the way to 30fps or less. I get around 50fps with an empty onDrawFrame, 45 with glClear and 35 with a quad.
The same code runs at 60 fps on the HTC Magic, on the Samsung Galaxy S, on the Sharp ISO1. Sony Experia X10 caps at a solid 30fps because of its screen. I have been doing much more complicated scenes at a solid 60fps on the HTC Magic which is very underpowered compared to the Desire. I don't have a Nexus One in handy to test. Sure, I except buffer swapping to block for a couple milliseconds. But it just jumps over frames all the time.
Trying to find out what the phone is doing outside of the onDrawFrame handler, I tried to use Debug.startMethodTracing. There is no way I can get the trace to reflect the actual time the phone spends out of the loop. At the end of onDrawFrame, I use startMethodTracing then save the current time (SystemClock.uptimeMillis) in a variable. At the start of the next one I Log.e the time difference since the function last exited, and stopMethodTracing. This will get called over and over so I arrange for stopping once I get a trace for an iteration with a 40+ ms pause. The time scale on the resulting trace is under 2ms time, as if the system was spending 38ms outside of my program, I tried a lot of things. Enumerating EGL configs and try them all one after the other. Just to see if it changed anything, I switched to a render when dirty scheme requesting a redraw at each frame. To no avail. Whatever I do, the expected gap of 14~16ms to swap buffers will take 30+ms around half the time, and no matter what I do it seems like the device is waiting for two screen refreshes. ps on the device shows my application at around 10% cPU, and System_server at 35%. Of course I also tried the obvious, killing other processes, rebooting the device... I always get the same exact result.
I've been playing with OpenGL but am unable to get a steady framerate due to GC. When rendering 100 tiles each frame (in ortho mode), the GC needs to recover ~22000 objects every 3 seconds or so. Each collection is taking around 110 ms. Of course this means quite a framerate dip.
... D/dalvikvm( 9837): GC freed 21841 objects / 524272 bytes in 113ms D/dalvikvm( 9837): GC freed 21841 objects / 524272 bytes in 113ms D/dalvikvm( 9837): GC freed 21841 objects / 524272 bytes in 113ms D/dalvikvm( 9837): GC freed 21841 objects / 524272 bytes in 114ms ...
The rendering loop I tested with is not making any objects and is very simple;
while (super.running) { gl.glClear(GL10.GL_COLOR_BUFFER_BIT); gl.glBindTexture(GL10.GL_TEXTURE_2D, tex); for(x = 0 ; x < 100; x++) { gl.glVertexPointer(2, GL10.GL_FIXED, 0, tileCoords[x]); gl.glTexCoordPointer(2, GL10.GL_FIXED, 0, tileTexCoords[x]); gl.glDrawArrays(GL10.GL_TRIANGLE_STRIP, 0, 4); } egl.eglSwapBuffers(dpy, surface);
I am trying out the (latest) Android SDK, and noticed some strange behavior.I've written a skeletal SurfaceView app: Activity, SurfaceView and a rendering thread. It doesn't actually do any painting, and only writes out the framerate to logcat once a second. When it runs in portrait mode, I get around 60 fps. However, when I flip it to landscape the framerate drops to about 30 fps.
I have also tested it on the LunarLender sample, and got similiar results. All of the testing are done on the emulator, since I don't have a physical device.What's it all about? I can't seem to find any mentioning to this on Google, have anyone else experienced that? Is it just an emulator quirk or does it apply to physical hardware too?
I wanted to write an application that makes use of the camera taking extremely slow frame-rate video and uploading it. Right now I am reading over this:
http://itp.nyu.edu/~sve204/mobilemedia_spring10/androidCamera101.pdf
My question was in regards to the camera's use. The above article makes use of a canvas to preview the image, if one didn't want to preview the image before taking it could that be done? Is it necessary to use a preview of the camera image or can I just call takepicture to take the picture and catch the resulting callback to save it to a file?
Anybody know the best settings for the NES/SNES emulators-frame rate, etc to get rid of lag? The first time I used it it was lag free, now I'm getting a little jumpy frames and stuff....(i bought the full versions of both).

Is there any way to change the frame rate of a application or game to be slower, some thing like freeze banana in fruit ninja.
I had some app in windows that did it with changing the clock slower for example one second in computer was 1.5 or 2 seconds long.

I'm looking into writing an Android game, tough I don't curerntly own an Android device. For those of you who own a device, how does the performance on the emulator relate to real device performance? I'm especially interested in graphics related tasks.This obviously depends on both the machine running the emulator, and the specific device in question, but I'm talking rough numbers here.This question is a duplicate, but since that post is heavily outdated, I figured it's irrelevant by now.
View 3 Replies View RelatedI'm getting started with Android development, but the emulator performance on my machine leaves much to be desired. In all fairness, my machine is not a powerhouse by any stretch of the imagination.
Short of upgrading my hardware or spending $$$, are there any good tips for improving Android emulator performance?
I've created an application that show around 250 images in ImageView. Images are loaded one after another, 15-30 images per second. Basically the whole thing gives an illusion of a rotating 3D object, at least it should.
The problem is next, app hangs when loading certain images(i.e. I see a few seconds of fluid animation and then animation hangs, jump 10-15 frames(images) ahead and continues. It always happens at the same places in animation cycle.
I though that Android might not have enough resources to handle something like this, so I've resized images to half their size, but it did't help. I've tried buffering images but that did't help either(actually, maybe a little, I think that animation looks a little bit smoother).
And now the weirdest thing. I use the touch screen to allow users to "rotate" the 3D object on those images, and while rotating I again experience those hangs at exactly the same places as with the animation.
All images are in .png format and their size vary from 15kB to 40kB.
I use the following code for the animation:
CODE:.....................
I am working on a compute intensive app for Android. I do not have any device yet to test performance. However, the performance on emulator is a bit slower than expected. I see an old question about some estimation of emulator vs device. What are your experiences while developing apps with recent SDK Froyo/2.2. Is performance observed on emulator is slower than actual device. Please share your experience and the specs of your dev machine and mobile devices, both.
View 3 Replies View RelatedA while back I mentioned that running the imported p2p codebase I have on the emulator (on a fairly powerful laptop with plenty of mem and a fast processor) was pretty slow. I blamed all that on the codebase and in fact I was able to profile it and make it much lighter. Well still the overall app performance is slow --- and I am finding that most apps I run on the emulator are fairly slow. Is this a common trend? I do expect emulators, who are by no means a real device, to have such processing delays but are they in general this slow? Any metrics or any other feedback from anyone that depict the factor of slowdowns you would expect on an emulator vs the real device? I know a lot of this are machine dependent as well but consider an idle powerful machine. And regarding memory - I am loading Eclipse with close to 1G to be able to run the emulator and its basic services - is that normal?

create an FBO of resolution less than the full phone screen dimensions (user-selected quality vs speed option) do most of my scene rendering into that FBO * then the 'real' (full screen) render would either use the FBO as the starting background color buffer contents, or render it (probably orthographically) as a single quad. * then probably add UI/Text decoration on top of that, where the resolutions really benefits.And, is there some egl glue (I am a glSurfaceView kinda dood) that would automagically do something like this in the first place?Or am I being naive to think the GPU could do its work faster if it was rendering to a lower resolution target? And would the phone with the worst fill rate also be the phone that doesn't support FBOs in the first place?

View 11 Replies View RelatedHey folks HumanMachine here with a little query for those of you who were lucky enough to have picked up a 32GB MicroSD for your phones.I had, and lost mine, in the course of two days. Short story incoming. TLDR Below I was using my phone at work and decided to change my Live Wallpaper, I'd downloaded a few of them and was going through them just to see how they looked in motion. I remember specifically looking at the "Starfield" wallpaper. I then selected the "Battery - Couple the ship's energy source with phone's battery" To see what the option did. I backed out to apply the Wallpaper. And the Droid X locks. Weird I thought, maybe she's just lagged.Turned out a lot worse than that. She was just straight up frozen. Stuck on this unusable frozen starfield. I couldn't quite remember how to reboot the phone. or even if it were possible, Couldn't power her down, so I removed her battery, figured that would be enough to get her back to life.I was met with a message, once the phone loaded up. "SD Card blank or has unsupported filesystem" Not the first time I've seen this issue pop up on the android forums. I immediately popped the MicroSD card into my little USB dongle and attempted to access the MicroSD. Shows up in "My Computer" just fine. but when I tried to access it? "Please insert disc" et cetera et cetera.
I try to format. No dice, Computer won't even find the thing. Try my SD formatter, no dice.Stick the 16 GB card back into the phone, and we're sailing again. And here I am staring sadly at the card.I tried for about an hour more to breathe some life into it. I just couldn't get the computer or phone to read the card. Same error messages.TLDR For those of you who wanted to skip the story SD Card died. pathetically, didn't lose much but still. My question, do we have any idea what the failure rates are on these bad boys? I didn't mistreat or even do much with mine before this issue came up. Hopefully I just had a lemon. Unfortunately, the store I got mine at. Verizon store actually, didn't have any, nor do they know when they will get a shipment of them.I'm bummed. go figure. Time to play the waiting game.
I'm new to development on Android and thought maybe you could shed some light on my problem. I'm trying to code up a little object to take care of playing a list of songs at a constantly varying playback rate. I just spent a god chunk of time getting it going with SoundPool only to find out about the undocumented 1 mb file limit. Do you guys have any ideas? Should I be using AudioTrack? I was going to try that next. Any tips or code samples for doing this kind of thing? It's such a shame that neither JetPlayer nor MediaPlayer support rate changes.

We been doing some testing of the G1 accelerometer on Android, and wanted to see if others have gotten the same result.Our test uses a partial wake lock to keep the CPU alive.It stores the xyz values and time to local storage and then writes them to a file on the SD card once a second.The code below produces a csv file.The xyz values we're getting are within the expected range, but the sample rate of the accelerometer varies greatly.To determine that using the file produced, for each sample, we found the difference between the samples timestamp (taken from the SensorEvent) and the timestamp from the previous sample.The test results showed the time between samples ranging from 30 milliseconds up to 4.6 second spikes.We're interested to know if other people are seeing similar behavior from their phones.If you have the time and means.
