How can I get battery level and state (plugged in, discharging, charging, etc)? I researched the developer docs and I found a BatteryManager class. But it doesn't contain any methods, just constants. How do I even use it?

Can anyone suggest me a nice app to see the battery level?
View 10 Replies View RelatedSearching old posts reveal that no one knows a way to get the current battery level without using intents. Is this true? There's no method to just return the current battery level?
View 4 Replies View RelatedIs 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.

Is there a way to get these two values anytime? Like when a user runs my program, I would like to grab the current values right away instead of having to wait for them to change.

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.
View 2 Replies View RelatedNew Incredible user just looking for some feedback, my battery stats are the following:
Uptime: 12:06
Awake time: 2:58
Battery use:
-Android system: 34%
-Cell standby 29%
-Phone Idle 22%
-Display 8%
-Voice calls 4%
-Maps 3%
I've been reading all other posts and their android system is significantly lower is there something draining my battery?
Android Version: 2.2 (but also happened on 2.1). My phone's battery level will suddenly drop to 89% even though it is still on charge. It's annoying because sometimes you'll start the day with only 89% charge instead of 100%. My friend also has a Desire but is not experiencing this problem - the only difference between them is the version of kernel. I read somewhere that is was the kernel that was the problem and somebody found a fix - xda developers - View Single Post - [DEV] Desire GSM/CDMA kernel 2.6.32 Google / 2.6.34/35 Cyanogen Mod.
View 4 Replies View RelatedI was just wandering if there is a shortcut to find the exact battery level on my Desire? I know you can go the 4636 route but thats slightly long winded, and most battery widgets/notification bar icons actually seem to use battery (i have properly tested this!). I know you can go into 'about phone' and do it that way but that just shows it as a series of bars, not as an actual figure.

View 3 Replies View Relatedso I decided to pull my battery out of my phone to check something.the battery level was at 30. I then put it back in and now its at 70. its been 20 minutes and its still at 70. Any insight on why this is happening?

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 don't know if this is an Android 2.0 or a Motorola Droid issue, but I noticed that the battery level only reports in increments of 10's. For example 70%, 60% etc. Any apps or widgets also can only see this as well. Is this a bug, what happened to the detailed stats?
View 6 Replies View RelatedI wrote a widget for Android and I'm trying to get the battery level.
I've tried using. Intent battery Intent = context.register Receiver(null, new Intent Filter(Intent.ACTION_BATTERY_CHANGED). but I get the error:
"Intent Receiver components are not allowed to register to receive intents". Why? the ACTION_BATTERY_CHANGED is a sticky intent and I don't register a receiver (null in the first parameter).
I was using the phone reading email and the battery indicator all of a sudden went from 50% to 5% and i got a prompt telling me to charge it. I knew this could not be right and i proved it by surfing the net for 10 mins and watching a video for 75 minutes before the phone died. Has anyone had this happen to them?
View 3 Replies View RelatedI was using satnav at the weekend; the battery level indicator on my Desire went from green to orange (20%) and the existent data connection dropped off straightaway. I was unable to re-establish a data connection even after switching the phone off and on again. I was in an area of reasonable/good network signal strength. The GPS continued to function however so I could still see my progress on the map but a data connection message appeared.
When I got home the phone continued to function on WiFi (with GPS on too) for nearly another two hours before it turned itself off, so there was plenty of "juice" left. My question is as to whether there is anything I can adjust to ensure that the battery continues to function fully (ie maintain a data connection) until it runs out? Or whether at 20% the phone is somehow set up to end a data connection? I have now got myself an HTC car charger to make sure the battery will not drop that low again when I am using satnav.
I have a compound UI component built up from a ViewGroup containing a number of TextView, ImageView etc. components. Many of these have StateListDrawables as their images/backgrounds. Is there any way of making them select from this drawable based on the state of the parent ViewGroup rather than the component itself? Ideally I want to be able to change the visual state of all children of the ViewGroup (text colour, image etc) based on the state of the ViewGroup, preferably without having to hook up complex logical code. This seems like a fairly common sort of requirement, so I was hoping it would be straightforward in Android - am I going to be disappointed?

I am wondering if there is an app that can power off my device when battery drops to a certain level. Tasker's shutdown task not seems working for me.
I'm a little confused by what I'm seeing with regards to phone state transitions via the PhoneStateListener. When I receive a call, this is what happens: (call comes in) RINGING -> IDLE (I pick up) OFFHOOK (I hang up) IDLE It's that first transition from RINGING to IDLE without any interaction from me (not ending the call, not answering the call) that confuses me. Do I really have to implement an idle counter to know that an incoming call has really ended? Seems like the reported phone state represents some sort of phone state that isn't the obvious one.Is this a bug or am I just not in tune with the paradigm here?
View 2 Replies View RelatedEver since I received the froyo update, my phone will randomly state "BATTERY IS FULL". This happens generally below 90%, sometimes as low as 60%. Even stranger, this only happens when the phone isn't being charged. And it never happens when the battery is actually full.

View 2 Replies View RelatedI have updated my tools to revision 7 and now I can't do a build as it says the API level is obsolete. I can understand warning but it won't build at all. I am using android.bat to generate a build.xml for release versions. So the build.xml gets made from scratch each time. If I switch to --target 8 it builds but I have already released it on the Android Market with 6. Won't this mean that some people that have Android 2.0.1 won't be able to run it?
CODE:........
I'm looking for some way in Android to play in-memory audio in a manner analogous to the waveOutOpen family of methods in Windows programming. The waveOut... methods essentially let an application create arrays of sample values (like in-memory WAV files without the headers) and dump them into a queue for sequential playback. Windows transitions seamlessly from one array to the next, so as long as the application keeps dumping arrays into the queue ahead of playback, the program can create and play continuous audio of any arbitrary length. The Windows API also incorporates a callback mechanism that the application can use to indicate progress and load additional buffers.
As far as I can tell, the Android audio API lets an application play a file from local storage or a URL, or from a memory stream. Is there any way to get Android to "queue up" MediaPlayer.start() calls so that one player transitions (without glitches) into the next upon play completion? It appears that Jet does something like this, but only with its own internal synthesis engine. Is there any other way of accessing Android audio in a waveOutOpen way?
I know about LocationManagerService, AlarmManagerService, and BatteryService, from Android programming books, but is there a published list of all available services?
