Android :: Possible Duration Of Idle Time Of Phone Based On Current Battery Level
Aug 18, 2010
I am new to the android programming environment. I am currently working on a project which deals with the user's phone battery level.I am showing the current battery level left on the phone.now i want to display the amount of duration of "idle time, talk time, video playback, audio playback and web surfing" that can be done based on the current battery level. What kind of approach shall i follow.(or) What available API shall i use to get those.

Is there a way to get the current battery status of the device (battery level and if the battery is currently charging). The only way I found so far is by using a Broadcast receiver to "listen" for battery status changes. Is there a way to get the battery status using a direct API call? I my case, I would like to check if the battery has sufficient charge (or is being currently charged) before starting the download of some (potentially large) files.

Just yesterday my phone was getting more than 14+ hours of battery. Now it's draining really quickly even when I'm not using it (I left it on while I was asleep). It's not facebook because I already downloading the fix and rebooted. My "time without signal" is 0% so I don't think that's the problem. I did download Quickpedia yesterday but a quick search tells me that's not the problem either.
The only other thing I did differently was switch from ADW to LauncherPro yesterday, but if that was draining the battery wouldn't it be under Android System and not standby or idle? Regardless, I switched back to ADW just to see if that works

I need someone to test my First app I did. It is reworked and extended version of Android DatePicker app here: Date Picker | Android Developers. I don't have Android creature, because I am out of the Google test area. My app shows Time Duration using the DatePicker Dialog twice
The result can be seen on the image.
Please email me and I'll attach the tDurator.apk for you. I need feedback about the working state of the app when rotating the Nexus 1 device, but anyone having at least Android system 1.5 (level 3 on the SDK) can run the app. The app is signed for release and in not harm to the phone.

So I have a API issue. So i am creating a class that utilizes AndroidHttpClient to download Bitmap images from my server. Problem is, it's API Level is 8 and I want this to be used FROM API 1 and above, now i know i can use DefaultHttpClient (the API is Level 1) but is there a way i can use both, being distinguished by Build.VERSION.SDK (btw thanx for the quick respose, Konstantin Burov and iandisme). So for example, if my device is 2.2 i use AndroidHttpClient, anything else use DefaultHttpClient. Of Course if I import the library it will give me an error on any device 1.5 to 2.1. Any Suggestions would greatly be appreciated, because in the future I would want to set other preferences based on API.

Now I write one app and have some problem - I need to show real-time outgoing call duration. But I do not know when I should start timer. I must start when get answer from other side. I tried TelephonyManager.EXTRA_STATE_OFFHOOK -- but it's state is when I press call-button..
OFFHOOK is the state when call is placed.
So we should be notified when the call is received. How can we get that?
When I should start count outgoing time?

I would like to know if android has some kind of 'idle time broadcast message'. So for example if the user is currently using one activity of my application but haven't touched the screen or used any keyboard (and doesn't have the autolock at phone level or any screensaver) for a while, I would like to be informed (let's say after 60 seconds). I would like to avoid doing it manually (by tracking each user click, touch, activity changes...)

Is there any way to show my smartphone battery level on my computer? Synced via internet.
It will be sweet to have those two bars (notebook and smartphone battery level) next to each other on the taskbar (win 8). I tried to google it, but unsuccessfully.

I want to develop a game, so I need to know elapsed time at lots places in my game. For example, to measuring FPS. I see there is some example use "System.currentTimeMillis" to measure elapsed time. But I see the warning on document: http://developer.android.com/intl/zh-TW/reference/java/lang/System.ht... "This method shouldn't be used for measuring timeouts or other elapsed time measurements, as changing the system time can affect the results." So, if this method should not be used for measuring elapsed time, then what will be suitable?

After hearing about the EVO's battery not lasting more than half a day, I was nervous to order the Droid X. I'm seeing some articles online stating that the battery life is pretty decent on the X. How have your experiences been so far? I have mine coming in the mail on Monday, and I'm hoping I don't need an extended battery that will turn my phone into something the size of a cinder block.

In my case I need to be able apply a color conditionally (for example based if an item is read or unread) so I need to be able to read the "read" and "unread" colors from the current theme and apply them appropriately.
I gave the color special attribute name in my attr xml file and assigned it different values in 2 different themes. if I do getResources().getColorStateList( <my attribute resource ID>) it fails because it can't find the resource. It seems like something needs to first resolve the attribute Id to the Id of the resource in the current theme, but I am not sure what does that.

In my application I have a list of +400 GPS coordinates which I retrieve from addresses. The application should give me the top X nearest coordinates based on my current location.
This application is possible (I think) with the distanceBetween function. But (I think) the application is really inefficient when i iterate through the list of 400 coordinates and check the distance within a certain time interval. Another option is (I think) the proximityAlert function? All coordinates are loaded in this function and when my current location comes in the radius of a coordinate an alert is given. But the downside of this solution (I think) is the high memory usage which implies a short battery life of the Android phone?

All I want to do is from time to time check my mails. For this, I want to activate the mobile network connection (3G) manually for a short period of time, and then de-activate it again.
The problem is that enabling the "mobile network" checkbox after my phone has been idle for some time, doesn't actually activate the 3G connection. (no "H" or "G" icon in the notification bar)
So when I open the mail app it complains with a "connection failed" message.
Even better would be if I could find a way to have my mails automatically checked whenever the connection is activated ...
Other than that I'm very happy with the phone.

I have tried searching the database for this and googled it and I couldn't find anything.
I'm not very experienced in Android, however, I am trying to develop an application. Within the application I want to check if the current time falls between time ranges
pseudo code
[HIGH]if (currTime > 9am AND currTime < 7pm)
{
//do this
}
else if (curTime>7pm AND currTime <10pm)
[Code]...

How can I determine if the current time is between two other time objects?
For example: current: 15:23, startTime: 22:00, endTime: 06:00. So the current time is not between this two other times, but this "23:47" is.
*I don't care about the date, only the time
I tried to do it like this:
Code:
Time startTime = getStartTime();
Time endTime = getEndTime();
Calendar c = Calendar.getInstance();
Time now = new Time(c.getTimeInMillis());
[Code]...
but it dosen't work well. their aren't any errors but it just dosen't work.
To be more precise the problem is that 15:35.after(22:00) return true... and I don't know why. I think that the problem is something with the dates but I don't know what

I tried doing the Airplane trick...I am not sure this is the 50% issue others have mentioned because when I go to view my battery statistics, it doesn't show the 2 lines of information like it did before (i.e, 50%), but my phone idle and cell standby are Both hanging around 36%...seems kind of high in my opinion.

Currently have a Nokia E71, Using Advanced Call Manager, which lets me record directly to the phone, I know android can't currently (hope it will one day),
However I'd like to deny all phone calls except those on the white list, according to a schedule, i'll divert them to my work phone system after work hours to record the voicemail there instead of on the mobile itself. Divert/Deny Phone Calls based on a schedule

I first have to say that I'm biased, 'cus I like to write music apps (like music generation apps). However, this affects games as well. It's somewhat disappointing how OpenGL has made it into the NDK now but there isn't any NDK methods to get to sound to have faster access. Over the weekend I did some more testing and if you make a "drum" app, for example, and play the sound using either SoundPool or AudioTrack, you will get about a 100ms delay buffer, which is clearly audible (gap).
I made a test app where when you touch the screen, upon the DOWN event, it would play a short sound (like a drum sound). It clearly was not real time responsive or even close - you could hear the delay. I'd be interested to know if anyone who has made a game has any trouble with sounds? It seems like they aren't going to really trigger real time enough if you use SoundPool, for example. Am I completely wrong? Seems like your game is going to perform an action, play a sound, but the sound will have latency which I would think would throw off the game a bit..................

I am trying to collect power usage statistics for the Android G1 Phone. I am interested in knowing the values of Voltage and Current, and then able to collect statistics as reported in this PDF.
I am able to get the value of Battery voltage through registering for an intent receiver to receive the Broadcast for ACTION_BATTERY_CHANGED. But the problem is that Android does not expose the value of current through this SDK interface.
One way I tried is via sysfs interface, where I can view the battery current value from adb shell, using the following command
$cat /sys/class/power_supply/battery/batt_current
449
But that too works only if the phone is connected via USB interface. If I disconnect the phone, I see the value of batt_current as '0'. I am not sure why the value of current reported is zero. It should be more than zero, right?
Any suggestion / pointers for getting battery current value?

I'm just trying to find the way to get current time. But I don't want to use currentTimeMillis() method, because the current time on device may be wrong. Is there any way to make some request to the Internet to get right current time?
