Currently, attempting to scroll when the text view has large amount of text makes the app completely unresponsive. It doesn't ANR, but it doesn't respond either. I've tried occasionally removing some text from the text view and removing some spans also, but it doesn't seem to help much. Any idea how to improve scrolling? It takes ages to scroll up or down. I also tried throttling touch events but it hasn't helped either.

Does anyone else find find the camera on the Desire extremely sensitive to any hand movement while taking a picture? I found the camera on my old iPhone 3GS much better in this department (although the picture quality overall was not as good). And I know that a phone is no replacement for a dedicated camera, but is there any way to improve the shutter speed/sensitivity to movement?

View 2 Replies View RelatedWhat kind of performance are you seeing with 6.1? I'm pretty unhappy with the speed it takes for the app slider, page scrolling and all that. I didn't run a quadrant score, I'm not really bothered about numbers. I switched to LP, that didn't help. Also, snap kernels are not playing nice with 6.1 yet (anyhow, the snap kernel features are reportedly built in), so nothing there. I'm back to myn2.2 with overclocking and it's smooth as silk.
View 22 Replies View RelatedWith 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 2 Replies View RelatedI'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?
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 read on many other topics that the Android emulator starts really slow. Indeed, it takes +15 mins to start. 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?

There's a ton of documentation on how to create *new* apps, but so far I've been unable to find any info on how to get *existing* apps into Eclipse. And my own attempts have gone so-so.
A good place for this information would be the developer FAQ for example: http://developer.android.com/guide/appendix/faq/commontasks.html

I have a droid and the range I get with wifi compared to a laptop is horrible. The networks I have tested on are all 802.11g. Is this just normal because of the antenna size on the droid or is there something I can do to improve it? I feel like I have to be right next to the access point to have a good connection.
View 2 Replies View RelatedThe 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?

Will 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.
Ok,this is my first android phone,coming from a bb I've notice that the battery life on my EVO sucks,I bought the phone yesterday and put it to charge while playing around with it.I unplugged the phone this morning at 7am,I make a 5min call,watched a 5min video on YouTube,I had Friend Stream running until noon along with Background Data,surged the web for around 2min,listened to 2 songs and a couple of txt messages and the battery on my phone is @ 40% as I'm writting this,notice that background data was turned off around 1pm at that point battery life was @ 60%.is there any way to improve this?I am not running ATk,by the way I love the phone,a lil bit of help will be apreciated.

My android application works well but it's performance(speed) is slow. In my logcat i saw frequent garbage collection operation like

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.

View 3 Replies View RelatedWhen 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.
Are there any Android phones that are multi-processor (multi-core/ cpu), where application threads execute concurrently on different processors?
There doesn't seem to be any explicit way of doing asynchronous file I/ O or asynchronous resource loading. So, suppose I put BitmapFactory.decodeResource() or Resources.openRawResource() into a separate thread. Will those methods play nice with the other threads, yielding during blocking I/O operations so those other threads can run?
If those methods rely on the thread scheduler to forcibly suspend them, then the separate resource-loading thread isn't going to help me get my application started any faster (although it will help it to be more responsive to user input).
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.
I have a HorizontalScrollView that has lots of views and images inside it.
The issue is that if I have lots of stuff inside it I will get a 'java.lang.OutOfMemoryError: bitmap size exceeds VM budget'
