Android has provided Power management framework for saving batterlife. But this is limited to screen/key lights. I am exploring ways to enhance this scheme for other use cases like camera, media playback by changing CPU frequency. I would like to know what support is available for this from Android kernel.

I just bought a G1 from a friend and am exploring how I am going to use this. I am not much of a cell user, I want this more for the wifi access and am playing with Google Voice. I have a pay as you go call plan, no data plan, and am in a wifi zone about 90% of the time I would want to use it. All is functioning well.
I am finding that the battery barely makes it through the day even with light usage. The power manager indicates that about 15% of my usage is wifi, even when I didn't actually connect. I am thinking that the device is working hard scanning for an open connection. Like I said, 90% of the time I am in a known wifi zone with a "remembered" account. So it doesn't really need to be looking all the time. What would be really cool is if there's an app to toggle wifi based on location. I think by GPS since it would be more accurate. Wifi could be off until I get to a given location, then it would automatically fire up and connect.
I am looking for an application that handles power management. I downloaded the Power Management app, but the free app has limited features. I am looking for a free app.

View 2 Replies View RelatedI went for a drive today and put the Evo on the mount I built for my car, plugged it in to the radio and also in to the car charger. I have Slacker Radio set to leave the screen on as long as it is connected to power. My battery was probably about 95% and during the drive, it was charging and, while listening to Slacker, the screen stayed on. However, not long before I reached my destination, my battery got to 100%, the green LED was on, and the screen would follow the 30 second shut off that my phone is set to. I could no longer get Slacker to recognize when the phone was connected to power. Anyone have a similar experience? I'm hoping this was isolated to that one instance (some perfect storm of other settings, use, etc), but I have a feeling it isn't.

I didn't expect the battery life to be great, but it's worse than I'd hoped,Obviously, setting the screen brightness to minimum is one way. I've also tried to see if you can 'turn off' applications which may be running in the background, but can't find a way to do this. My previous Nokias allowed you to see what programs were running, and you could turn them off to save battery power. I know a selling point of the Hero is that you can switch to applications quickly without 'loading them up', but is this killing the battery?

View 4 Replies View Relatedi was wondering about the hydra kernals. I installed the latest overvolt hydra kernal. My question is when you go into idle, does it underclock for you? Or do you have to install undervolt to do that? Also can you install both overvolt and undervolt at the same time? (not literally at the same time but have both kernals at once to get the most power and battery saving?)
View 6 Replies View RelatedI currently have a personal (HTC Touch Pro) and business phone (iPhone). With Sprint now offering unlimited any-mobile (freeing up 1300+ minutes a month on my family plan) and Google Voice allowing me to get a separate business number, I'm thinking about dropping my iPhone, and replacing the HTC with either a BlackBerry Tour or a Hero. I work in project management; I know that the BB does have applications that would be useful to me (as does the iPhone), but I can't find comparable apps for Android. As a personal phone though, I would rather have the Hero. Given that I've only been able to spend a limited amount of time browsing the Android Market in a Sprint store, I was hoping someone here might know of some good replacements for my "must have" apps.
1) PIM / Task management. I have a lot of tasks, meetings, and deadlines to manage. I need something similar to the functionality provided by Outlook. I currently use Pocket Informant on the iPhone, which allows me to view multiple calandars, see my schedule from the month-level view, and integrate my to-do lists. I can also assign calander events and to-do tasks to projects, give them priority, provide extra notes, add multiple reminders, etc.. I could probably live with the Android's calander, but I definately need a good to-do app.
2) Time tracking. I have an app on the iPhone (TimeLogger) that lets me track how much time I spend on projects for clients. The one I currently use allows me to start a timer and then come back later to stop it, which is helpful but not a must.
3) Personal finance manager. I track all of my purchases, have several accounts / cards, and need to be able to track/filter business vs personal purchases.

View 2 Replies View RelatedIs it possible to reboot an Android smartphone as a non-smartphone(Like a Nokia 1100) ? Just enable only services to make phone calls and everything else remain disabled(Slow down the CPU to the lowest clock speeds, lower bit depth, turn off all on-board electronics other than those necessary etc). Motivation is to save power. In my phone most of the power is consumed by Android OS (and not screen). I was wondering if I had a mode like that I could keep the phone alive in case I can't charge the phone immediately, by switching into this power saving mode.

I usually use my DEXIM. but it does not work with the Behold 2. I've tried a car charger/battery unit by Wireless Gear that said it was compatible with all Samsung phones, it came with 5 power tips and a USB outlet that still would not work, even using the OEM USB cable. Any suggestions would be appreciated. I will go with OEM Samsung if necessary, but there selection is limited.

View 6 Replies View RelatedI'm new to Android, having just received my shiny new HTC Hero. So far, I love the phone and Android. But, I have a quick question; I don't use DHCP on my wireless setup at home, which is fine, as I can obviously set a static IP for the wireless, but, I would also like to connect to wi-fi in the office, where I'd need the phone to pick up IP details from DHCP. Is there an app that lets you configure wi-fi settings so that it will use the static IP address when connected to my home network and DHCP when connected at work? I know I can just turn off the static IP when in the office, but that's a bit of a pain. I can't just turn on DHCP at home either as I have a slightly unusual setup, where the wireless access point is behind a broadband router, and it doesn't allow me to specify a default gateway within it's DHCP options, so, whilst a wireless device can connect to the wireless network with DHCP, it has no way of routing to the internet without having a static gateway specified.
View 4 Replies View RelatedI recently switched from an Iphone to a nexus one. I am getting used to android and loving a lot of the features. My first complaint with android was no real sync software but I found doubletwist and while its not perfect it does a pretty good job. My second gripe is that media is split between the music player and the gallery. I miss how the iphone had photos for all of your photos and video you took on the phone and then the ipod app for all of your music and movies. Is there an app out there to organize all of my media and showcase it in a better manner? If I had that then I would be set with my phone.

More specifically.. I want to see for sure what apps are running on the phone, what apps are running on SD, etc.
Stock management shows whats on SD, but not whats on phone, unless I'm missing something.

View 1 Replies View RelatedSo im new to this phone, and im a little confused about app management. I see there is a "last used" list (holding the home button), but doesn't say whats running and whats not! some apps, like the market seem to remember the last view, so they start there and feels like there where running all along, but where they? let me give you a Reallife(TM) example. i open youtube, and choose a video. while is loading (not fast connections around here), i switch to the mails, and when i come back, the video did not only not load, but it went to the previous screen.but apps like meebo, apear in a special "notification" are of ongoing things ..should i assume that things not going in that special notification area are not running? is not that i feel the phone slower, is just that im a control freak. i would like to know how it work.
View 2 Replies View RelatedI am working on an application for android and we since we have lots of graphics, we use a lot of memory.
I monitor the memory heap size and its about 3-4 Mb , and peeks of 5Mb when I do something that requires more memory (and then goes back to 3). This is not a big deal, but some other stuff is handled outside the heap memory, like loading of drawables.
For example if I run the ddms tool outside eclipse, and go to sysinfo, I see that my app is taking 20Mb on the Droid and 12 on the G1, but heap size are the same in both, because data is the same but images are different.
So the questions are: How do I know what is taking the memory outside the heap memory? What other stuff takes memory outside the heap memory? Complex layouts (big tree) ? Animations?
I'm looking for a little more information about dialogs managed by activities than is provided here:
http://developer.android.com/guide/topics/ui/dialogs.html
And havn't found any good web resources. In particular, I'm having a problem where a dialog must be updated in onPrepareDialog() with Activity member variables that change after onCreateDialog() is initially called. During an orientation change, version 1.5 will only call onCreateDialog() and not onPrepareDialog() for dialogs previously used (and not dismissed).
An example problem scenario's onPrepareDialog() steps are listed here:
CODE:.............
The result of not calling onPrepareDialog() during orientation change, if the dialog is currently being displayed, is an empty spinner.
In 1.6, onPrepareDialog() is also called and so this problem is not seen.
As a workaround for 1.5 I simply remove the dialog in onResume(), but obviously if the dialog is showing on orientation change the user experience is not ideal.
I don't expect this is a 1.5 bug so much as a lack of my understanding regarding what the "right thing to do" is in such a situation, where information is not known at dialog creation time.
I'm unfortunately going to have to post this in a few places because I don't know where it's going to get the most exposure, but I'll start here because I have a Desire. I need an app to manage the various projects that I have going on. In some ways, you can think of it as a todo application which has subtasks, projects/groups, action lists, sorting via time till due/time taken/project/importance etc. If you have the time, check out this site where there guy goes through a number of options and criteria for a good GTD (getting things done) application.

the Android web site indicates that "all applications are created equal". What is the strategy to ensure that critical applications/ services have priority? Are there any facilities Android does provide to ensure certain applications and/or threads to receive a minimum of CPU bandwith (and other apps/threads are prevented from consuming all the CPU bandwith)?

1. When the "copy protection" checkbox was first introduced on Android Market, I heard about a lot of issues with people not being able to download etc. Have those issues been resolved now? If I turn on copy- protection on an app with over 10K active users, do I risk a major rebellion?
2. I'd like to sell my app on other stores like slideme, andappstore and handango. Since some of these just redirect the user to your own site to download the app, there needs to be a license key that authenticates the user and unlocks his app. I saw that andappstore has a framework for that (not sure if that will only work with them or is a generic solution). I'm looking for a free, generic licensing solution. Is there one that you know of or use? My concern is to not throw in a wrench in the process of user download and use of the app, where I start getting a ton of emails from people whose keys arent working or asking for new keys etc, where license support turns into a full-time activity.
I have a problem with my application, and it's about a Virtual memory error: ERROR/AndroidRuntime(19790): java.lang.OutOfMemoryError: bitmap size exceeds VM budget
The story is like this: I have an activity (let's call it A), the user click on a button from this activity, then i will make an api call somewhere in the internet, and after the result is back i start a subactivity (let's call it B).
In the activity B i have to dinamicaly load some images from the resources folder. I load the images into bitmaps -> drawables -> imageviews. After the user click's on some buttons i have to setResult(..), finish(), and get back to activity A.
The thing is that, goes from activity A to B, then B -> A, then A -> B for a few times, my app crashes with the message above: it doesn't have enough memory to load the interface.
I can not maintain the activity B on the stack because i don't want the user to go to this activity without going through activity A first.
During the installation of my Android SDK, I am getting stuck during the process where the manager goes out and downloads all the revisions of the APIs and the SDKs.
It is potentially due to a socket issue that typically occurs when a database query is called and there are a large number of TCP connections... according to googling my error (No buffer space available (maximum connections reached?): recv failed )...
So I just need to know if there is a way, other then using the Android download manager, to download / update my computer with the following Android SDK components:
