I've been trying VBOs (3D) and I've seen no improvement at all on my Motorola Dext over not using VBOs.I've tried all kinds of configurations, interleaved arrays, by t buffers instead of float buffers, both direct and indirect. My question is, has anybody got any measured improvement in frames per second by using VBOs instead of exactly the same content without VBOs? If and only if so, what were your fps results? And can you therefore show me the "proper" way of doing VBOs instead of not? Has anybody else got exactly the same fps with and without VBOs?

However, on my machine is slow even after that.The 'phone' responds with a 3-4 seconds delay and everything has a huge lag.Is there any way to improve the performance of my laptop (Asus 1201N) is too rusty for the Android emulator? Tried in different emulator resolutions and the result is the same.My laptop has 2 cores with HyperThreading. And it shows as 4 CPU in Device Manager. However, when using the emulator, just one of the graphs is at 100%. Can I do something to make it work multi core?
View 5 Replies View RelatedI'm getting started with Android development, but the emulator performance on my machine leaves much to be desired. In all fairness, my machine is not a powerhouse by any stretch of the imagination.
Short of upgrading my hardware or spending $$$, are there any good tips for improving Android emulator performance?
The game I am working on uses SoundPool for sound effects and MediaPlayer for background music playback. Input happens entirely through the touch screen, with a 20 mS delay after each processed MotionEvent. Sometimes (very rarely) it happens that the background music gets interrupted for a fraction of a second during input. Do you have any ideas how to ensure MediaPlayer continues audio playback during touch screen input? All audio files are in ogg format with various sample and bit rates. Would it be an advantage if all audio files would share the same samplerate and/or bitrate? Do you have any other ideas how to improve audo playback performance?
View 4 Replies View RelatedWill Android 2.0/2.1 improve performance? The Eris is a cool phone and all but it simply cant keep up with me. There is nothing wrong with my phone also. I have rebooted it and have 80mb free memory. Same thing at Verizon store display phone. It just cant keep up and the lag and waiting periods (1 second or so) are annoying me. Yes one second is alot of lag time when you are trying to do things. It sounds like "only one second" but there are 100 of these one second lag times all over the phone. Im not even an "expert" or "hardcore" user.
Anyon know if Android 2.0 will run faster? Playing a simple MP3 while trying to navigate the phone increases the lag times. Why dosnt the older iphone 3g have these lag issues when they both have equal CPUs?
When will Google and HTC aknowledge the MAJOR issue with the ENTIRE phone slowing down the a crawl once available RAM goes under 30mb. (common with all Android phones) Is it SO hard to have the ability to shutdown apps and automatically remove them from ram when Im done using them? This is the same stupidity Windows Mobile went through back in 2003. Yes I understand that Android will remove unused apps from RAM to make room for the next one but this is where the lag is coming from. The entire phone slows to a crawl unless you free up some memory with 3rd party apps.
My android application works well but it's performance(speed) is slow. In my logcat i saw frequent garbage collection operation like
11-02 15:07:20.647: DEBUG/dalvikvm(12571): GC freed 295 objects / 38448 bytes in 93ms
Is this the reason for low performance? How can i improve my applications performance?
I have notices following:
If I have a project with minimum files in res folder, the project saves quickly, compiles quickly and launches quickly. But if I have a lot of resources, my project is saving, compiling and launching during relatively long period of time. This is really frustrating if you do some minor UI updates, and you have always wait Eclipse to generate R file etc.
Bad performance has plaqued my phone since I updated it with 2.2. It's like it has the desire software on the legends hardware. Gets very sluggish after 1 hour of being turned on.
Not that much running either. Anyone else had problems?
I'm dying here with the 5 minute (non-aGPS assisted) fix times and frequent losses of fix.
View 6 Replies View RelatedI have a couple friends with the Eris that went from loving their phones to hating them shortly after receiving the 2.1 OTA upgrade. They were quite happy with 1.5, but were looking forward to 2.1 - because I bragged about the improvements in the leaks.
I was playing around with their phones last night and they were having serious lag when scrolling, receiving calls and switching from portrait to landscape mode. I turned off window animations completely and those issues went away immediately. The phones are now pretty speedy.
If you're looking for that setting, it's under: Settings > Sound & display > Animation > No animations.

View 9 Replies View RelatedI have seen some threads and articles on a few sites talking about the advantages of a better than stock mSD card for the Hero having a drastic effect on its performance. I have see others stating that a Class 4 or even Class 6 card on the Euro HTC Hero has improved performance by 400%. Now while I know "400%" is a little out there and even sounds exaggerated, I am curious what this group of people has seen or heard. Does a better MicroSD card improve overall performance?
View 13 Replies View RelatedI've always said that the Behold2 is a great looking phone. It has software/OS issues for sure. However, I don't use the cube so, that bit of nonsense doesn't get in my way. The laggi-ness does get on my nerves because it slows things to a crawl much too often. Sometimes programs or the TouchWiz slider don't open when they should. Frozen-ness happens too.
The scary part is that I have very few third party apps installed. Sometimes the controls for the Media player don't show up at all. So you can see why I am reticent to install anything beyond what I consider to be essentials so as not to over-burden an already beleaguered setup.Considering these known issues, why were we ignored on the Android 1.6 release? We weren't graced with 2.0 either. Now 2.1 is on the horizon and there is no word about its being sent our way. I'd like to think that Samsung or Tmo wants to keep us happy so that we don't jump ship in a few days. I could dump this puppy because I am within my 14 days and am not a happy camper.
Questions: What if anything will an upgraded OS do to improve the performance of our processor? Or, what improvements might we expect with a new OS release?

View 7 Replies View RelatedI'm looking into writing an Android game, tough I don't curerntly own an Android device. For those of you who own a device, how does the performance on the emulator relate to real device performance? I'm especially interested in graphics related tasks.This obviously depends on both the machine running the emulator, and the specific device in question, but I'm talking rough numbers here.This question is a duplicate, but since that post is heavily outdated, I figured it's irrelevant by now.

With my location listener i get accuracy values about 30-100 m (being on an open field without annoying houses around me disturbing the gps signal). Why is that so bad? I thought you could get an accuracy about 3m with gps. And the Google maps applet for example has a much better accuracy. How can i improve the accuracy? I'm using the default gps provider. I saw you can create a Criteria object to get the best provider, but there are only the gps and the mobile phone net providers anyway - so it's some kind of senseless to get the location provider that way. is there no way to define the needed accuracy?

View 8 Replies View RelatedWhile I think the Google Mail app is ALRIGHT I think it needs quite some improvement so I am wondering if there is either a good alternative to it or if someone added features to it / modded it.
1)problem: i can't select any text from any emails (written by others or myself) which isn't too great when writing emails. is there any app for selecting text maybe? it's something i miss a lot on android. if i want to select text on a website I need to switch to Skyfire.I just can't believe coding a text selection is really hard so I don't understand why google didn't add it themselves yet.
2) problem: when I'm on the go and sending an email and the CONNECTION dies for a moment the Google Mail app will be stuck at "Sending..."I guess it is stuck in a loop then and it won't send out my email but I also can't go back so I can only close Google Mail with a task manager. Can't this be fixed, too? I just want a GO BACK feature so that it won't get stuck in a loop. Maybe just an automatic Save Draft just when someone clicks Send and then goes to the Send process and then you get the option to force close that and just go back- I dont know.

I am currently writing a paper on the Android platform. After some research, it's clear that Dalvik has room for improvement. I was wondering, what do you think would be the best use of a developer's time with this goal?
JIT compilation seems like the big one, but then i've also heard this would be of limited use on such a low resource machine. Does anyone have a resource or data that backs this up?
Are there any other options that should be considered? Aside from developing a robust native development kit to bypass the VM. For those who are interested, there is a lecture that has been recorded and put online regarding the Dalvik VM.
Any thoughts welcome, as this question appears subjective i'll clarify that the answer I'll accept must have some justification for proposed changes. Any data to back it up, such as the improvement in the Sun JVM when it was introduced, would be a massive plus.
