Android :: Excessive Number Of Touch Events Slows Down App

Feb 26, 2010

I'm writing an Android game that needs to receive touch events. My problem is that, whenever the user drags their finger along the screen, so many touch events get sent to the touch event handler (which I think runs as a separate thread) that my frame rate plummets! What's the best way I can limit the number of touch events that are handled per second? For example, if my game runs at 60 fps, I really shouldn't need more than 1 touch event being handled every second. Can I do this is a way that doesn't lose any information (i.e. important information about where on the screen the user touched last)?

HTC Desire :: Stability - Rarely Slows Down

Jul 31, 2010

Will probably regret saying this but I am very impressed with the stability of this phone. It never crashes, rarely slows down and I have never had to reset it. In fact, I only turned it off the other day because it had been up for about 300 hours and I thought I better refresh everything.

The only errors I have ever received were a couple of "some process has stopped running", but upon clicking okay everything kept on working and I assume the phone simply restarted the failed process.

HTC Hero :: BT Music Playback - Slows Down - Speeds Up - WTH?

Dec 14, 2009

Whenever I try and playback music via BT, regardless of music player (I've tried 3) the music playback speeds up, slows down, speeds up, etc., and will NOT play at a consistant speed. All background processes are disabled, etc. I do NOT notice this same thing during video playback (although there is a 40ms delay in audio sync from the video), but it plays at a constant speed.

General :: Droid Bionic - What Slows Down Smart Phone

Sep 23, 2011

I currently don't have a slow smartphone but when I had my original Droid it would really slow down until I put a new or updated rom on it. Even if I rebooted it it would still be slow. I now have the Droid Bionic and it's really fast but will it someday get slow? I guess I don't understand the smartphone technology very well, yet. Is there or will there be some sort of software that you can run that will speed it back up?

Android :: Animation.start - Or Animation.startNow - Does Not Start The Animation Immediately

Aug 30, 2010

I have a strange issue - from time to time the animation that should fade out my control (ImageButton) does not kick in immediately. I am using the fadeout animation to hide it and then in myListener on its end (onAnimationEnd) I put new resource as the image on the button.

Somewhere in my app code:

Animation a = AnimationUtils.loadAnimation(this,R.anim.fadeout); a.setAnimationListener(new myListener(location)); buttons[location].setAnimation(a); a.startNow(); // regardless if its start() or startnNow() it will work in most of the cases but not 100% reliable I actually can see in debug Log when its late, happens after few more clicks

Then in myListener.onAnimationEnd(Animation a):buttons[location].setImageResource(R.drawable.standard_button);

Seems there is a rule that the every 4th or 5th animation does not start ...

Android :: How To Speed Up Animation?

Jul 21, 2009

I have a static background image, and a foreground that needs to be animated. I tried a couple different approaches but the animation seemed choppy. One thing I did was having 2 different views, constantly calling invalidate() on the foreground view. Another was to have only 1 surfaceview, redrawing the background image and the foreground on each step of the animation.

While a surfaceview offers an optimal way to do heavy-duty animation, having to redraw the background every time kills the performance. Neither produced a smooth animation. What is the best way to perform this kind of animation - static background and animated foreground?

Android :: Animation Is Slow

Oct 22, 2009

I'm trying to perform a simple animation, but it seems quite choppy. This is it: Animation anim = new Translate Animation(0,0,-50,0); anim.set Duration(500); anim.setInterpolator(new LinearInterpolator()); myLinearLayout.set Animation(anim);the animation does what it's supposed to do, just very choppy - is there any reason why it's so slow? The linear layout I'm applying it to is pretty simple, just has a few children.

Here is what i have done and what i want to do further: An application starts with a 2D object [ball] rotating and execising in a particular fashion, and after a particular point in time the object [ball] scrolls out of vision. After this point i want to invoke a new activity with a different UI. I m stuck up while trying to transit from this View to a new activity.

Android :: Add Some Animation On App Widget

May 31, 2009

When writing an App Widget based on Cupcake, I create a remote view like this:

views = new RemoteViews(context.getPackageName(), R.layout.widget_loading);

However, the widget_loading.xml contains <ViewAnimator>. The ViewAnimator don't have @RemoteView tag, so it's can not be inflated in remote view.

To fix this, I define a MyViewAnimator (which most likely the ViewAnimator in android) with @RemoteView tag in my project. Then use MyViewAnimator class in the layout xml file. But it failed, there was a exception that class loader cann't find MyViewAnimator class.

So the problem is: how to use any animation in the remote view? Is it possible adding some visual effects on app widget?

Android :: Way To Implement Animation?

May 30, 2010

I have a widget that periodically updates itself (hourly) to display top result of search query. I would like to extend it so it captures several top results and then loops through these. The best example would be Genie News and Weather widget for which I was unable to find a source code. What would be a good way to implement the animation? I'm thinking ViewAnimator + timer, but is there maybe a better way, say FrameLayout + alerts? I'm already using AlertManager to periodically pull search results for the widget How bad such arraignment would affect phone's battery life?

Android : Way To Create An Animation?

Jul 29, 2010

I need to create an animation - Flip a view and show another one. The width of currently shown view is decreased slowly to zero and after that the width of the view-to-be-shown must be increased from zero. During this time, the height goes from the currently-shown-height to slightly-decreased-height and back again.

Android : Animation Across Two Layouts?

Aug 10, 2009

I've met a problem with animation when tried to make a View to perform the animation which should cross 2 layouts, e.g. make a translate animation so a view could move down to the TableRow below. This trick works fine when i try to move a view within a single TableRow but not when i try to move it up or down. I've also discovered that if i create a single RelativeLayout and apply the same animation there, it works fine, but i can't arrange all the components i need on the screen. Could anybody please provide me any hints about it?

Android :: Flickering - Animation Towards Right And Left

Aug 26, 2010

I am doing an application-infinitely rotating 3D cylinder in openGl.The speed varies with finger touch but wen i reduce the speed,i can see flickering happening in animation towards right and left.Initialy I thought it is because of the linked list im updating but found out there is no such problem with my linked list .I'm using a thread here for a small delay after each 30 degree rotation drawing.I cant do it widout the thread coz i need a sleep or a delay after each 30 degree drawing,if i remove the thread and implement the code in thread inside my onDraw frame, the curvature rotation itself goes and it appears that images are just left shifting n right shifting coz the sleep is not getting identified in onDraw frame.So i cant implement my logic here widout using thread..so thread is a must in my logic but i guess the flickering is due to my thread...Is the flickering issue during animation because of the thread?please do help me with this flickering issue......

This is d thread part im using in my code.........

Android :: Getting Transformation Matrix Of An Animation

Apr 1, 2010

I would like to obtain the transformation matrix of an animation to calculate the position of the view that was animated.It seems the Animation class has a method called getTransformation that can be used to obtain the transformation applied to the view.However, if I use getTransformation before starting the animation I obtain the identity matrix.The program enters an infite loop because getTransformation seems to trigger onAnimationEnd (why?).How should I use getTransformation to obtain the transformation matrix of an animation? Is there another way to do this?

Android :: UI Animation - Showing An Arrow On Top

Sep 18, 2010

I'd like to show a large green arrow in front of all other views when the user clicks a button. The arrow should fade in, stay there for 1-2 seconds and fade out again. How would I go about programming this? I've looked at the animation examples but would like to confirm the way forward before I dive into programming something that won't work :-):

Draw the arrow-image as a bitmap, immediately make it invisible Fade it in ("alpha"-change animation)
Let it stay for 2 seconds Fade it out (again, "alpha"-change animation)

Is this correct, or would you suggest something else?
