On iPhone, Mobile Safari is WebKit based and supports hardware-accelerated -webkit-transform CSS properties. To be specific, I use the translate3d() transform.
What alternative is there for the Android browser? I need it to work on Android 1.5.

I am drawing a pretty simple scene, with one large texture the about size of the screen (two triangles). I notice that the frame-rate is irregular: in most of cases, a frame finishes in 17 ms. However, in about 1 of 10 times, the frame finishes in 33ms.
My guess is probably some background services need to run. However, the Linux scheduler is biased towards my FG app, so the BG services are usually starved, until they can't take it anymore and they grab the CPU from my app ....
I am seeing stuttering in the animation. Is this due to the irregular frame rate? Should I delay each frame so that all frames are rendered with 33ms frame time? If so, what's the best technique of achieving this?
Is there an API that I can call to guarantee CPU resources for the render thread .... I really hope Android runs on some sort of real time kernel ...
Looking to buy an android tablet such as the tf700, and the only thing holding me back is the browsing experience. Now i had the tf200 on ics and the browser was no where near as smooth. So have things changed at all?
View 3 Replies View RelatedHere's a general question... I have an evo and there are apps like the htc gallery where smoothness of the animation are just as good as the iphones.
But why doesn't the browser zoom and scroll as nice as the iphone browser? Don't we have enough horsepower to match the quality as the iphone rendering?
I've been developing Android application for quite awhile now. Please correct me if I'm wrong, but as far as I know the UI toolkit and 2D graphics API aren't hardware accelerated (the official documentation states that Canvas is not accelerated). I've found that most non- trivial animation or blending operations are painfully slow even on mid-level devices like a Droid, even after taking much time to optimize my code.
I'd like to know what the rationale is for not providing hardware support for these frameworks? Wouldn't it be possible to at least make it optional for vendors to implement support? Does anyone have any additional information about this issue?
Ways to implement H/W acceleration for video decoding(eg. H.264) in my own app for a long time, but got no clue.
I want to call H/W decoding based on NAL or frame level over raw bitstream, rather than setting up a media player for files.
I'm trying to create a transparent (no button background) ImageButton that has a custom selector. I have the selector working against the button but I now want the selector drawables to cross-fade into each other.
I saw the TransitionDrawable object that can be represented in XML. Is there a way to connect this into my selector?
Below is the XML layout code to create the image button on the screen in the lower left corner of the screen. It currently goes from one image to the next abruptly ignoring the transition XML.

In android 1.5 release notes I saw Animated window transitions.
What is this all about ?
IN my application i want to show trasitions if i go from one activity to other.We can set the animation for both activities and call when one is closing and other is opening.
But problem is when , the current animation will stop when the onCreate of next activity is called ?
Means , when activity is pushed to stack , ongoing animation is stopped. Because of this we cannot show a smooth transition effect between activities.
Is it possible to disabled activity transitions altogether and still maintain compatible with 1.5 ?
View 2 Replies View RelatedLong story short, how can I disable the screen transitions between activities? We implemented our own tab handler if you will, and now it is doing a transition between tabs, which looks pretty tacky.
View 3 Replies View RelatedUsually when the activity started using intent ,it uses from right to left transitions.i want to start activity that uses from left to right transitions.
How to do this?
I have stock gingerbread launcher and I wanna faster homescreen transitions, and faster entering in app drawer and also how to change icon pressed/focused color on homescreen and in app drawer (I wanna that invisible). I know decompile but don't know where and what to modify.

I currently run a Nexus 4 (Jelly Bean, CM10.1 Linaro) with a modified framework-res.apk file with ICS transitions.I know how to create animations (I am an android developer) but wouldn't it be cool to implement them on our system?In the anims folder of framework-res.apk you find all of these xmls containing different animations
Code:
accelerate_quad.xml
accelerate_quint.xml
activity_close_enter.xml[code].....
Some of them are pretty obvious (toast_enter.xml for example) but i dont really know which one does what.
Is it possible to do polling in Android? For example, I want my application to monitor a directory continuously. If there is for example a new folder created in that directory I want to log it down. Is it possible to acheive this by polling? Or is there any other way to do this?
View 7 Replies View RelatedI have a webview and need to trigger a function when a user clicks on particular url. How can I achieve this?
View 5 Replies View RelatedSo I'm struggling a bit with what is probably a fairly basic concept.. Activity Lifecycle.I have read a bunch of thread on the topic, and I feel I understand well both the functionality, and rationale behind the lifecycle model implemented for Activities, but it raises a bit of a problem for me. My app (game) has a couple of distinct Activities for various sections:
1. The TitleActivity is a very small Activity that just launches a GLSurfaceView and renders a startup logo.I use this to detect the OpenGL capabilities of the device (eg so I know if it's using a software renderer)
2. The LaunchActivity is the main menu screen where the user can access options etc and start a game
3. The GameActivity will either launches a GLSurfaceView or a standard View depending on hardware capabilties.
The issue I am having is that I want to pre-load some "slow-to-load" resources, specifically audio, in the Title Activity so when the Launch Activity renders I can play some background music.I have the concept of a "media library" which I use throughout the game.Because of memory limitations in the SoundPool, I have limited this to only absolute real-time sounds and all others are played using mulitple instances of MediaPlayer.Hence my media library has a bunch of pre-loaded MediaPlayer instances which I access regularly during game play.. so it makes sense to have a centralized access point for all audio.All fine, however the problem is that when I launch one activity from another.. for example the TitleActivity starts the LaunchActivity (via a call to startActivity(Intent...)), the former goes through the onDestroy stage of its lifecycle.Now logically I had assumed that if I allocate a bunch of resources in the onCreate of an Activity, I should clean them up in the onDestroy, however in the case of my "media library" if I load up the audio files in the onCreate of my TitleActivity they will be torn down when the LaunchActivity is started because the TitleActivity will have its onDestroy() method called.
I'd like to populate a listview from 2 tables. Anyone know how I can achieve this? Currently what I have looks like but it only works with one adapter.

View 2 Replies View RelatedThings go fine, and i am able to design a layout like this...
View 3 Replies View RelatedI would like to have a layout with 5 times 5 buttons. Each of them should have the same width and height (they should be square). And I want the whole matrix to use the screen width (or height, depending on rotation).
I currently do it "by hand" in the Java code:
CODE:...........
This can be improved by obtaining screen width first and then dividing by 5 to get rid of this literal 60. But I'm wondering how I can do this in the res/layout XML file? How can I specify for the height to be the same as the width? (I can set the width to match_parent.)
When i use toast to display some text on screen it displays little bit above the bottom(default position).
now i want to display it in the middle of screen or according to my choice can any one guide me how to achieve this?
When using a mediaplayer to play back an audio file, you can set looping to true - that's not the issue here.
If looping is set to true, there's still an audible gap between the file finishing and then starting again.
How could I achieve true gapless playback? I've attempted using two instances of the same file, overriding oncomplete and onseek.. can't seem to improve the gap though.
Strangely I find no support for Midi in Android.
The only thing that comes close is the Jetplayer, but this only takes a existing .jet file.
I want to dynamically generate a midi file with some intervals and play it.
I even thought about just manually creating a .jet file with a tone and then transposing it with the jet player, but it limits the transposing to -12, +12. Which is not so good for me.
There also is a ToneGenerator on Android, but it's limited to predefined tones with no way to transpose.
Does someone know how to achieve midi generation and playback on Android?
I am working on a application, in which I want to show Image gallery containing full screen images. I have put the gallery in the application successfully. But I am failing to apply some properties to the gallery as per the app design demands. I am using android.widget.Gallery library of android. The things I am failing to do are:
1) I wanna scroll the gallery images one at a time, as now its getting scrolled more than one images in one scroll.
2) And on scrolling the gallery, the images coming next from left/ right should move smothly into the screen and should stop at the screen edges. It should not scroll beyong that in one scroll.
Probably this question is answered. If it is, could you point me in the right direction then.
I would like to add the smooth scrolling functionality into my application.
i.e. I have a huge text and I want to scroll it automatically (like in book readers)
Could anyone offer any examples of smooth scrolling?
In my app i have gradient as drawable which i am using as background and i want it to make it look as smooth as possible. After googling and trying by myself i came up with the following. On nexus one if you call only setDither(true) your gradient is still banding so you have to set PixelFormat like this Window.setFormat(PixelFormat.RGBA_8888). But on the other side G1 does not support RGBA_8888 so calling it make the gradient even uglier than before so Window.setFormat(PixelFormat.RGBA_8888) will not work well on devices that don't support it.What is the correct way smooth my gradient on all devices on which my app will run.
