My girlfriend just got an HTC hero and I got a chance to play with it.
Even though it's specs are obviously less than those of the Droid it worked so much smoother, and I just don't understand why. Does android 2.0 just need to go through some growing pains?

This is more a question for those who have experience with rooted phones. For me, the biggest feature of Sense UI is how smooth it is in terms of transitions between screens, scrolling within things such as the Apps menu, etc. (couldn't really care less about the social networking integration).
Now, there are some homescreen apps out right now that are definitely (in my opinion) better in these regards than the standard Android UI, but they all still fall short of what Sense (or Rachael or even MotoBlur) has achieved.
Is this same smoothness, though, something that can be achieved if/when (since it really is just a matter of time) people figure out how to root the Droid and make custom ROMs?
Originally this was posted in the Velocity ROM thread but I'm sure most Ally ROMs will be able to benefit from these fixes:
The following will enable JIT and tweak your windowsmgr to allow for smoother scrolling. Using ADB pull your build.prop:
abd pull /system/build.prop
add this line to the end of the file:
windowsmgr.max_events_per_sec=60
This will enable smoother scrolling.
Next, find the following line to enable jit:
#dalvik.vm.execution-mode=int:jit
and uncomment it by removing the # before it
Save the file and push back to /system/build.prop
reboot and your phone should be a little more responsive
I was having some permission denied errors when pushing the build.prop back via adb, so here's what i did:
(this part is optional, if your phone pushes the build.prop fine, then don't worry about this)
adb shell
su
mount -t refs -o remount,rw /dev/stl5 /system
cd sdcard
busybox cp -R build.prop /system
mount -t rfs -o remount,ro /dev/stl5 /system
sync
reboot
**to those having trouble w/ the busybox command, make sure the build.prop is in the sd card, the sd card is not mounted in the computer, and you are in the adb shell of the phone
also, make sure you are cd into /sdcard/ and can see build.prop in the root of your sdcard with ls then try to
busybox cp -R build.prop /system
alternatively if that doesnt work maybe try adb push build.prop /system/build.prop
Tested on Velocity 0.1.1 but may work with other ROMs.
Has anyone noticed that the lock screen seems to be a little less smooth than before? I know it's something little but I was curious if I was the only one who noticed this.

View 3 Replies View RelatedI 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.
I tired installing the 2.2 update, but as many of us have seen problems have been occuring. I updated my sisters radio to the version that changed the start up screen. I didn't root the phone or apply any other update except for that one. Obviously I need to downgrade what I did to the stock. I downloaded SDK and will attempt to follow this:

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.

View 12 Replies View RelatedI've been plugging my phone into my car audio and running my slingplayer while on my long morning commute, in which i travel through a few areas that are out of 4G coverage. When this happens, the feed fails and doesnt start back up till i reconnect the slingplayer. What I've had to do basically is turn off 4G completely so I stay on 3G all the way. Anyone notice this on other applications on EVO (or the Epic, I guess)? Anyone having issues with pandora, hulu, subsonic, youtube, etc? I remember back before the release of evo at the big new york event they said transition between 4G and 3G would be smooth but my personal experience has shown it not to be while streaming.

View 4 Replies View RelatedI am working on an porting an application supporting segmented video streaming to Android. For those who are not familiar with segmented streaming, it is when a complete video is divided into multiple segments. Each segment can then, for example, be encoded at different qualities to support different clients.
Anyway, my problem is that I am not able to get a smooth transition between segments. Currently, the only way I have gotten segmented streaming working, is to write the segments into independent, temporary files, and then load each file into the MediaPlayer once the previous has finished. This causes an interruption in playback between each segment, probably due to the I/O involved.
I have looked around for different solutions, among others, playlists and storing the videos directly in memory. However, none seem to work or be supported by Android. Also, I tried creating two MediaPlayer- objects and do something similar to double-buffering by preparing the next segment well ahead of the previous, but it only made the application unstable.
My question is therefore: Does anyone have any hints, tips or examples for how to do smooth transition between video segments? The segments I am working with are independent, so there is no dependency and they can be viewed as X number of independent video files.
I am showing a RSS feed in my application using Webview as ListItem and it works great except that it is very sluggish at times. Since I don't know the size of the content then I can't set the height of each Webview and therefore I have the following code (this is the code for a single ListItem)...
But the "wrap_content" causes the Webview to readjust size when scrolling. The scrollbar-indicator of the listview also has problems knowing the size of the complete list so it changes size when scrolling. All this causes a very "jerky" experience when scrolling.
Is there any better way of doing this?
Why does everyone seem to hate SenseUI? I find it beautiful and very smooth. I wouldn't want to remove it when I root my phone. I also get very good battery life after my recent battery tweaks.
View 30 Replies View RelatedI 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 ...
On iPhone, Mobile Safari is WebKit based and supports hardware-accelerated -webkit-transform CSS properties. To be specific, I use the translate3d() transform.

I got a simple 2D tiles generator working, im reading an int map[100][100] filled with either 1's or 0's and draw tiles according to their tile id, 0 is water, 1 grass.
Im using some basic Numpad control handler, using a camIncr (32.0f), i set the camera position according to the movement :
CODE:.......
In my draw loop, im just drawing enough tiles to fit on my screen, and track the top left tile using cameraOffsetX and cameraOffsetY (its the camera position / tile size )
Im using a GLU.gluOrtho2D for my projection.
Here is the draw loop inside my custom renderer :
CODE:.............
my tiledBackground draw function :
CODE:..............
The waterTile and grassTile .draw function draw a 32x32 textured tile, might post the code if relevant.
Everything is fine, i can move using numpad arrows, and my map 'moves' with me, since im only drawing what i can see, its fast (see http://stackoverflow.com/questions/2129125/android-opengl-es-simple-tile-generator-performance-problem where Aleks pointed me to a simple 'culling' idea)
I would like my engine to 'smooth scroll' now. I've tried tweaking the camIncr variable, the GLU.gluOrtho2D etc, nothing worked.
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?
View 2 Replies View RelatedI am creating an app that show some histograms off your traveling speed in different time periods (histogram for the last minute, histogram for the last 2 minutes etc.) I would like to have an animation, and have discovered that drawing everything takes around 300-400ms. Which is to long for making my animation smooth, the animation itself is quite simple (2 lines and 2 dots). What I draw every frame right now is 20 antialised strings, size 14, in average ~5chars 8 of these strings will change every second. 1 of the string will change with the animation (this will become 5 strings if there is time).
The main part of the screen, the one showing the histogram data, consist of a lots of squares which needs to be updated every second. (450 squares). The presentation is split into 5 frames in the same view (has to be same view as arrows in one frame might point into another frame). Invalidating only a part off the screen makes almost no difference (it does becomes a bit faster, but i still execute all my drawing stuff). I have tried to add a flag whether or not the main part is dirty, but if I don't draw it, it is cleared. I might be missing something here. One possibility could be to render all the mostly static stuff to a bitmap, and then simply draw the bitmap. That would mean 10 strings only had to rendered on orientation change.
I think it would make sense since the slowest routine is the one drawing all the text. (the following is a typical timing for the drawing routines, accumulated).
V/HMMULTIBAR( 352): 0 - Drawing time: 0 ms V/HMMULTIBAR( 352): 1 - Drawing time: 53 ms V/HMMULTIBAR( 352): 2 - Drawing time: 62 ms V/HMMULTIBAR( 352): 3 - Drawing time: 85 ms V/HMMULTIBAR( 352): 4 - Drawing time: 280 ms V/HMMULTIBAR( 352): 5 - Drawing time: 303 ms
I would really appreciate comments about whether or not offscreen rendering is the way to go, or if there is a simpler way.

View 3 Replies View RelatedI'm drawing a rect to a surfaceview. Nothing special, just a test like this, in the surfaceview-extended class:
private int mPosX = 0; private Paint mPaint = new Paint(); Code...
the rect just bounces around the screen. I'm watching DDMS, I still see the garbage collector being called, even with this simple draw loop. There is no other application code being executed.
I'm wondering if it's realistic to expect the gc to not be called at all if we take care to not allocate any objects during our draw loops. I'm trying to extend this example to do some smooth animations, but every once in awhile the gc is called and you can see the drawing stutter. Although none of my application code is allocating any new objects, I don't know what the underlying API is doing inside surfaceview etc, and I doubt we can control that. Just wondering if this is not possible, I'd prefer to abandon this game idea up-front if we can't guarantee smooth animation.
My friend own a samsung galaxy s(available in Singapore) and i lent it to use.I find it having some lagging issue. Example when clicking application tab and back to home it isn't smooth at all and when i open AMPED(A Singtel application) the phone hang for like 15second and said the application is not responding. Samsung galaxy s should be a better phone compared to hd2 however my friend own a htc hd2 he doesn't have any lagging issue. Any idea why?

I implemented a gallery, and inside it I have many listviews from left to right. For some reason Gallery works great with all views but not with listview. With listview, when scrolling on the gallery, sometimes I get little jumps.
Some notes: The gallery uses an adapter to find out what to show, and then the listview is created based on the adapter
Here'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?
Not sure if anybody has this issue. I have a telus HTC hero and when I am in the music player, whether it be the stock player or not, if I let music play in the background, then lock/unlock the phone or if it sits with the screen on and then locks by itself, the music will skip or "cut out" for a half second and then continue. I don't remember youtube reviews of the phone music player showing this happening. Anybody else have this issue or does your music play smoothly regardless of locking/unlocking?
