On my system, i am using eclipse ganymede version along the Android SDK and ADT plugin installed. I have created an android AVD (target android 1.5) with 512MB of memory. Its quite frustrating to see the slow boot up of it. It takes around 4-5 mins to complete its boot-up. Is there any way or tweak to speed up this boot up process.
PC config:
P4 2.4 Ghz with 1 GB ram.

I am using Eclipse for Android development and Latest version of Android SDK (Running XP, 2Gb Ram)
1. when run clicked, previously executed emulator appears first then emulator default screen appears, only last current actual output appears
2. when clicked to close takes too much time (2 mns) for the emulator to disapper
3. in short execution time exceeds development/coding time in the testing process
is anyway to reduce such execution time

I'm playing video on Android using media player via RTSP. The player takes about 12s to buffer before it starts playing. Anyone know how I can convince the player to buffer less? I have full control over the RTSP server and the SDP it returns.

at the moment I am thinking about a new app and need some information to decide whether to develop on Android or an alternative OS. I am particularly interested in "time to first screen", "boot-up time", "time to first Audio" and "app-start" (can be any from the android market or even one of the pre-installed ones) time? Does anyone know a source or perhaps measured those numbers?

Well I've been using a class 6 microSDHC card, and it seems like the "Loading SD card..." time that appears when doing such things as opening albums to view pictures is still the same - several seconds. That leads me to assume that this sd loading time has a lot to do with the properties of the device itself (i.e. processing power, software efficiency).
With that said, will we ever see a reduced "Loading SD card..." time in the future? Perhaps from the coming Android 2.1 update? Do you custom ROM/Gumbo kernal users also have a several-second "Loading SD card..." time even with a class 6 sd card?

I was wondering if anyone knows of any way to set the phone so that, if your phone is already turned off, it will boot/startup itself at a certain time?

I have a Live Wallpaper app that is working very well on Eclair but there is a strange issue with Froyo that I can't find any information about. The user is able to select a custom picture as a background from their gallery and it will be saved to internal storage (/ Snowflakes/CustomBG.jpg) and applied as a background to the live wallpaper. That all works fine until the user reboots their phone... The problem is that the internal storage doesn't seem to be mounted in time for when the live wallpaper starts and so it reverts to the default setting when null is returned (see code below). As I say, this problem has only been introduced with Froyo as Eclair works fine (the image is found and used so the internal storage must be mounted before the Live Wallpaper starts).
Here's the code that searches for the CustomBG.jpg image on startup...
CODE:................
Apologies for the code formatting - is there any way I can improve this? Anyway, I'd be very grateful for any help you may have... I can't find any information about this on-line so perhaps there's something wrong with my code?

I'm having some boot delay in my Galaxy Ace. It runs 2.3.4 gingerbread and takes 1 minute to boot up ! When i bought it, it was very fast indeed, arround 20~40 seconds to boot.
My boot starts with the Samsung words, then an android animation comes, it ends, then something writed Google in the screen and bellow it has the loading circle, the same when you're waiting a video on YouTube.
I can do something to speed it up ?

No major issues, but my startup screen does seem to take a LOT longer before the phone actually loads, and once it does none of my buttons/widgets appear for another 5-10 seconds. Additionally, once in a while when exiting a program none of the buttons are on the home screen for 3-5 seconds, and sometimes a Force Close error pertaining to the home activity will pop up ... anyone else experience anything similar, or even just notice a longer boot time?

I recently bought a used, but in good condition Optimus V. Not a great phone, but it does what I need. However, in the past couple days I've found that when the phone does its auto-timeout, it takes up to ten seconds for it to switch back on. By that I mean that when I press the power button just to get to the passcode screen (not to turn the whole thing on), it takes much longer than it did when I first got it.
I've uninstalled recent apps, but it's done nothing. What to do?

Reducing Lag Due to Location Based Services (Tested with myTouch)Only use GPS or Network Based Location services but don't have both enabled at the same time.I purchased the myTouch on 08/20/09 running Firmware 1.5 (Cupcake), Build Number COC10. I am also using the 4GB card that came with the phone.I found that Sherpa and Google maps tended be less than accurate and lagged significantly despite being in Downtown Seattle with 2 - 4 bars of service depending on building density.I also had Pedometer running (a free app from the Market). Sherpa was exteremely laggy to the point of being useless in both Carsel Mode as well as Map Mode. I didn't use Satillite nor Street View in any of my testing.
When I killed Pedometer, I found Sherpa seemed to improve a bit, but still, it was very clumsy to use due to lag. I then looked at "Security and Locations" services and saw both "Use wireless netowrks" and "GPS" enabled. I first disabled "Use wireless netowrks" and saw an immediate improvement in Sherpa. I reenabeld the Pedometer and still got a good response from Sherpa and Google Maps including reduced lag and more precise location. I then disabled GPS (and told the applications to cancel when asked to enable) and enabeld Network based services. Sherpa, Google Maps and Pedometer all responded well, location services improved in accuracy and little lag.

When I install my app on the phone to test, it is showing up to be a HUGE size, 11.35 MB. It is a very simple app that lets user browse through fun-facts. The only reason I can think of is that there are 14 JPEG files in the drawables which serve as background images of the fun-facts. The average size of these is about 500 KB.I'd like to trim the size of my app, so as not to use up the precious resources on the user's device. Other than just getting rid of the pictures, are there ways to optimize the size of apk file?

I've managed to get my allocations down to next to nothing using DDMS (great tool), this has drastically reduced my GCs to about 1 or 2 every 3 minutes. Still, I'm not happy because those usually cause a noticeable delay in the game (on some phones) when you interact with it.
Using DDMS, I know what the allocations are, they are Strings being converted from integers used to display game information to the HUD.
I'm basically doing this:
CODE:.................
This happens once each frame update and the HUD system is modular so I plug things in when I need and this can cause 4 or 5 hud elements to allocate Strings and AbstractStringBuilders in DDMS.
Any way to reduce these further or eliminate all the String allocations and just reuse a String object?

In the Android phone, while I am watching YouTube videos, I may reduce the audio volume. Once I am done watching, I close all applications and leave the phone. Then when there is a incoming call, the ringer is very feeble. I may miss that call.Can you make the volume adjustment apply only for that application? I don't want the ringer volume get changed.

I'm finding my screen is too bright for me to read with in bed at night, even when set to the dimmest setting and with the background black and the text brown. I had this same issue with my old Palm Tungsten E2, but there was a program that allowed the screen to be adjusted to even lower than the manufacturer's level. Is there a similar app for Android? (Actually, I find my screen too bright at the best of times, too.)
