Android :: Maximum Refresh Rate Of Widget

Oct 17, 2010

I know that the default is 30 minutes, however I am looking at making a game in a widget.This would require millisecond responses.... has anyone messed with the AlarmClock Timing that is described to use instead to achieve this? does it work well?I haven't finished the Software Arc for the project yet because I see a lot of complaints about this on the net, so need to know if this is feasable before I go for the adventure... but the game would consist of a large widget size of one screen... many areas to click on and interact with and multiple textured animations

Looks like I can draw to a canvas and then pop it up to the bitmap to do this... but that still confuses me a bit.but I am struggling with the concepts of this code having an ID for the canvas and how to use that so I have not been able to test this code(I am a experienced c/c++/c#/dx/opengl coder first time with android and java)

General :: Can't Change Refresh Rate

Jan 29, 2013

I have been using admob for three months now..i have 12 android apps requesting ads from admob...2 of them from amazon app store (added last week)..others from google play.The problem is that since about 4 or 5 days i can't make any write changes to my account...this includes

1.cant change refresh rate..
2.cant add new apps..
3.cant modify the market url for existing app(for my new apps from amazon store,which has the same package as another app from google play.For admob it should be like same app requesting 2 ads..is that a problem?)
4.cant change colour of ads.that's all I have checked until now..When I try any of these,i simply gets logged out from admob..then i will have to login once again..

There is no problem with reporting and revenue updates.I have tried from Chrome and IE.

Also,i would like to point out a change in admob login..Earlier I could login to Google with another 'Google id' while logged in to admob..But now it seems they are connected. Logging out of Google logs me out off admob too..

HTC Desire :: Friend Stream Widget Never Refresh

Apr 29, 2010

Had my Desire for about a month now, and am loving it, but have run into a problem over the last week or so. My friend stream app has stopped working. The widget will never refresh, and whenever I try and go into it an error: "The application Friend Stream (process com.htc.friendstream) has stopped unexpectedly. Please try again" just keeps popping up, and I have no choice but to force close. I've been hearing rumours it could be another app I've installed that's causing it.

Android :: Way To Refresh An Activity / Map View Refresh Fails?

May 3, 2010

After implementing some Android Apps, including several Map activities, I try to refresh the activity when the GPS listener's onLocationChanged() mehtod is called. I have no idea how to tell the map activity to refresh on its own and display the new coords. the coords to store will have to be in global values, so that the location listener will have access to it. In my sample GPS-class (see code below) I just changed the text of a text view....but how to do that in map view?

Android :: Fil-rate Workaround With FBOs?

Sep 12, 2010

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?

Android :: Fastest 2D Frame Rate Possible With NDK?

May 20, 2010

Fastest 2D frame rate possible with android NDK, my try included, better options available?

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:

CODE:.........................

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:

Android :: Failure Rate On 32GB MicroSD

Jul 27, 2010

Hey 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.

Android :: Variable Rate Audio Playback

Mar 14, 2010

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.

Android :: Varied Accelerometer Sample Rate

Jul 9, 2009

Has anyone been able to get the accelerometer on the G1 to sample consistently for long periods of time? 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.

Android : Way To Check Charging Rate On Phone?

Jul 19, 2010

I want to install a USB charging port in my car similar to this. Before I disassemble the cig lighter adapter I have and put it inside the console, I want to make sure that it's one that can provide a full charge, not just a trickle. I'd read that the trick is to get one rated at 1000mA which I did, but I've also read that some charger with that rating still can't provide more than a trickle charge. Short of plugging in my phone to that charger and using it for a while to see how quickly it charges, is there any way to see if the phone is getting a trickle or full charge?

Android :: Media Server Service Upped Bit - Rate Over 3G?

Oct 17, 2010

Downloaded this update a few days ago and have yet to run into a song that sounds horrible as it did initially (even some in version 1.5 were a little off). I also noticed I'm receiving more data according to the Media Server Service. Think they upped the bit-rate over 3g? This is strictly speaking of audio streamed over 3g. I cant find a change log for Pandora....Anyone else have any thoughts on the new version? BTW I am a subscriber to Pandora One and use this in the car during my commute through the AUX IN in my stereo.

Android :: HTC Specific Open GLES 1 Frame Rate / Can't Get It Right

Sep 14, 2010

I 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.

Android :: Opengl - Unable To Get Steady Frame Rate Due To GC

Jan 29, 2009

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);

Android :: Frame Rate Drops In Landscape Mode

May 24, 2010

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?

Android :: Application For Camera Use - Slow Frame Rate Video

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?

Has fps ever been lifted before? Or are we spitting in one hand and wishing in another?
