General :: Change Frame Rate Of Application Or Game To Be Slower

Dec 6, 2012

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.

In android 4.0.x in developer optioons there is this thing for animations only.

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

Nov 24, 2010

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?

HTC EVO 4G :: Has Frame Rate Cap Ever Been Broken Before?

Jun 27, 2010

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?

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 :: Emulator Performance - Frame Rate Is Really Low

Aug 23, 2010

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?

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?

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..

Android :: Loading And Showing A Lot Of Images In ImageView - Frame By Frame Animation - Hangs In Certain Moments

Feb 18, 2010

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:

Building A Frame By Frame Live Wallpaper

May 19, 2012

I'm trying to build a live wallpaper using frames. I can't find any good tutorials on how to even build a live wallpaper. When I run app from eclipse i get these errors.

[2012-05-19 22:26:32 - LiveWallpaper] No Launcher activity found!
[2012-05-19 22:26:32 - LiveWallpaper] The launch will only sync the application package on the device!

It does install to the emulator. It all seems to work. I go in to the live wallpaper menu, find my live wallpaper in there open it, it loads. but its not moving through the frames. It only shows the last frame. I set it as wallpaper. It also doesn't do anything. Also would like to center the images.

import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.service.wallpaper.WallpaperService;
import android.view.SurfaceHolder;

Android :: Frame Animation Or Movie File For Short Interactive Movie Application

Jul 22, 2010

In a nut shell, when the app is loaded, it will play a short movie (maybe a few seconds at most @ 12-24fps). I will then have 2 buttons displayed on the screen, and depending on what button is pressed, it I will play another short movie (5-10 seconds). While waiting for the user to make a decision, the movie will be looping.
The movie source is stop-motion photography so it's already chopped up into frames. My question here is if I should use a Frame Animation technique, or if I should use a Movie player for this. All in all perhaps there's less than 100 still frames that make up the stop-motion. I was going to go the Frame Animation route, but I wasn't sure if having so many individual frames would kill the app so I thought I'd post here to see if anyone had any insight.

General :: RAM Usage - Phone Become Slower?

May 10, 2013

i always listen about the ram used in android is different than windows..

My first question is, why RAM is like 90% used, the phone become slower??? My second question is, Why 99% of apps are always started with phone, when enter in Applications section, and see Running apps, you see millions of apps, or when you enter like, Calculator or Torch or another app details it appears Stop.. WHEN I STARTED IT?

Im now user of Galaxy S Duos, when i have Motorola Atrix using a custom rom named "Neutrino" my ram, after flash it was 80~90 and here in Galaxy S Duos is 390~500 and the max is 685mb so so, than when press clean RAM, it closes a certain number of processes but only 50mb ram max it decreases... Why?

General :: Mobile Become Slower After Being Idle For A While?

May 10, 2014

i have Samsung Galaxy Y Duos GT-S6102 Android 2.3.6.

I am using the Stock ROM, My mobile is rooted.

I am also using GO Launcher EX and Go Locker.

When i am using my phone for a while it is fast, for example switching the AppDrawer screens, Open Messenger close it again, Go to home screen instantly after pressing ( Home ).but when i leave my mobile for a while ( 10min + ) it become slow ( when i unlock the screen the Home screen appear after a while, the app drawer take long time to load and is laggy while switching screens, opening an application take a while too.

Notes :

1- I Don't have any Auto-Task killer applications ( i had before but uninstalled it )

2- I noticed that my phone lose Internet Wifi connection too, because when i open FB messenger it show me the "Connecting" message.. i also doesn't receive notifications after leaving my phone idle for a while.

3- When i unlock the phone and start using it the notifications are revived ( delayed notification )

Does underclocking make video run slower? i'm on the htc inspire with Absolution v3.7. i undervolted it aggressively to -75. i also underclocked it to 384. but i dont think underclocking is the cause since i had underclocked this phone with virtuous unity to 384 and videos played well. anyway, i noticed with netflix, video runs slow every 4 minutes then normal again.

General :: HTC Desire HD Slower For Some Time When Screen Unlocked

Mar 12, 2012

I'm using the Oxygen ROM on an HTC Desire HD. When I leave my phone alone for a while and come back to unlock it, performance is often slow for 20 seconds to the point where swiping between launcher screens is sluggish. After this time it goes right back up to normal speeds.

Is this possibly related to the CPU settings in my ROM? The settings are available governors - interactive, min CPU - 245MHz, max CPU 1024 MHz. My guess is that when the phone's idle it goes down to 245MHz and takes a while to get back up to regular speeds. Am I looking in the right place and how much would increasing min CPU frequency affect my battery life?

General :: How To Change Active Root Application

Sep 22, 2012

So, my ROM comes preloaded with a root app that I've never heard of, and I want to use Superuser (and the Elite I paid for).

The bundled app came with a 'cleanup/uninstall' script, that I ran, that promised to remove itself and it's root-granting abilities.

Now, even though I've got Superuser (Elite) installed, apps are saying I don't have root.

How do I configure Android (or SU) to use SU as my root-granting application?
