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.

I'm fading out an imageview with alpha animation. I'd like the image to stay transparent after the animation. Tried with different combinations of fillAfter and fillEnabled, no luck. How can this be achieved?
View 1 Replies View RelatedI 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 ...
Is it possible in Android to get a callback when a Frame Animation (AnimationDrawable) has completed playing its frame sequence? I know when a Tween Animation has completed, it calls onAnimationEnd(), but is there something similar for frame by frame animations?

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?
I am working on some animation application where i am trying to apply 2 kind of animation on the TextView.
During onCreate() of the activity I am rotating it by 45 degrees & on onTouch() event i want it to translate & then rotate it to proper shape.
But on onTouch it comes to normal shape & then translate & then again rotate.
How to keep old state of the TextView?
I have doubts while doing some 2D Graphics and animation. 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.

View 1 Replies View RelatedWhen 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?
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?

View 3 Replies View RelatedI 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.
View 1 Replies View RelatedI'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?

View 11 Replies View RelatedI've got a Nexus One running a debug version of my application, and I just today downloaded and installed the 0.9.8 version of the SDK tools, and I swear that Debugging latency has increased incredibly. I never bothered to measure the overhead before the upgrade because I always found the phone's debugging overhead to be small enough to not affect matter. Well, now I have AI code which runs at ~10 MS standalone taking 300-400MS through debugging. A 40X performance loss is not something to cough at. Is it just me not seeing the performance loss previously, or has something broken?

View 4 Replies View RelatedI've followed the excellent article on game development here: http://www.rbgrn.net/content/54-getting-started-android-game-development, and started my game based on the Lunar Lander example. The Lander example re-draws the background and everything else on each "tick". I basically followed its example and I'm using my game's background image to essentially "clear" the canvas so that I can re-draw everything from a clean slate. This, as I've found, has a negative impact on performance as my game is beginning to slow down. My question is, what's the best way to optimize this? If I want to "clear" only certain parts of my canvas, how do I do that? I've read the documentation for android.graphics.Canvas, but am getting confused by a lot of jargon I don't understand such as "clip" and "matrix".
View 2 Replies View RelatedI am trying to do AES decryption like this -Cipher cipher = Cipher.get Instance("AES/ECB/PKCS5Padding"); cipher.init(Cipher.DECRYPT_MODE, aesKey); cipher.update(encryBytes, 0, encrByteCount); and it is taking me about 2.5+ seconds to run just the cipher.update (i.e. I excluded the init and get Instance() calls) for 65KB of data -- which seems way too long.What this translates to (roughly) 60 seconds for a 1.5MB file. Which is uber slow.I *am* actually seeing 60 or so seconds when I try to decrypt that big of a file (looping through and feeding buffers).Does anybody know why AES decryption is so slow on Android? A co- worker is seeing times around 10 seconds for the same file on a RIM device.
View 2 Replies View RelatedI have a rooted mytouch 3G and I've been using the barnacle tether app for the last few months for internet on my laptop. Just recently I've been playing online poker on my laptop. It worked fine for about a day or so, then things started to get extremely slow, barely being able to load google (taking about a few minutes to load a basic html page). I don't know if it has something to do with using my phone for a connection with the poker clients or if it's just coincidence with the timing of it, I called T-Mobile and they said there are no problems at all with the coverage in my area and to do a Power cycle which didn't seem to help. Does anyone have ANY idea what could be wrong?

View 2 Replies View RelatedI am developing a small app that works as a speedometer with a build in histogram.
But it is quite unresponsive, I test it by driving in my car, and when i go from 80 to 0 it takes about 4-6 seconds before my needle is updated.
For simple outlier removal, i use a 1x3 median filter on my estimated speed the speed. Wich obviously will give me a delay one 1 sample.
******* Here's the real question :) ****** I thought i might get updates every second, and thus a delay of 2 seconds, wich wouldn't be to bad. but is GPS really that slow? or am i doing something completely wrong? *******
I have registrered a listener like so:
CODE:..............
To have a steady update of my speedometer, I use a timerTask to poll the listener for the last estimated result, and updates my speedometer view.
CODE:............
And the run method of my task:
CODE:.....................
I am currently using sensors and I would like to know if I can slow down the sampling rate. Indeed, I register my listener with the constant "SensorManager.SENSOR_DELAY_UI" (is it the slowest one of the four constants mentionned in the documentation?) but the rate is still quite high. I would like to be able to define the time before giving the new value (For example, I would like to wait two seconds before update).

View 2 Replies View RelatedI am starting a service from a broadcast receiver, using android:process=":remote", which from what I understand means unbind. That BR dies. The service is runs some TTS (text2speach) in a cycle until a second broadcast receiver comes into action and executes stopService.
I am using action names to start and stop the service.
The problem I am having is that after the stopService is executed the service is still alive for a good 20 seconds when finally dies from timeout. The other think I notice is that onDestroy() is never called.
