How do I find that out? I've been looking a bit at the Intents API, but AFAIU I can just subscribe to events from there, and a subscription is not what I'm after. And even if I *did* want updates, I'd still need to know the initial state.

My Droid X wont charge when its turned off. When I plug it in the green charge light comes on then the phone boots up and shows its charging, but if you shut the phone off while its plugged in, it wont charge. The green light stays lit but no charge in the morning. So if you boot it up, it will charge when turned on. With my DINC it was best to charge the phone when it was turned off. This is all pluged in and charging from my computer. I am getting about 12 hours on a full charge, thats about 4 more hours than I was getting from my DINC.

HTC Desire - When I first receive my phone, do I need to charge the battery?
It states 8 hours. Which should I follow? Also, can I have it switched on while I charge so I can set it up? And I imagine I should let it fully discharge before charging it again, but how many times is this appropriate for? The first 2 or 3 or more times?
I have a rooted droid running bbv1.0 and Ive had this for a couple of months now. I recently lost my wall charger so I have just been charging it with the data cable and the computer. Today I was gone most of the day and my battery was at 15% when I got home. I plugged it into the computer for about an hour and when I came back it still had the same amount of battery life when I unplugged it to check. I have setcpu and it was doing the failsafe warning (over 120 degrees) a little more than usual today. It got up to about 145 degrees for a minute at one point when I was using the wireless tether with my laptop. It had the failsafe warning when I checked it while charging just a little bit ago. I don't know if the battery is failing or if its a problem with the phone?

When I plug the charger into my phone, a short tone plays. How can I replace that tone with one of my choosing? Right now, the file I want to use is a midi file but I could change it to another format if I need to.

Does it effect battery life in anyway?

Can someone explain a couple of very simple concepts to me - I'm interested in mobile devices running android and how they are identified over networks. Some scenarios: Device is connected over WiFi - presumably the device has a standard IP address as with any host and can communicate with any other android host over TCP/IP (assuming it knows the participating device's IP? device is connected over bluetooth - how are devices identified in this case? device is connected over mobile operator's network - this is the one I'm interested in and confused by - is there anyway for two or more devices to discover each other and communicate via the mobile operator's network? How does a device communicate with a backend server in this scenario? In other words, how do apps and devices communicate when not connected to a WiFi network?

I have created my database using sqliteman browser b/c I have to insert a bulk data before the app starts. I have four tables in my db and call each in different activities and created all on the sqliteman. after the data is inserted I pull back the db onto the data folder of the emulator. it works perfect on the emulator but failed on the device. when I try to pull my db on the real device, it shows access denied problem
View 2 Replies View RelatedI have developed a sports game which is single player. Now I want to have one more game mode which is multiplayer.
My question is how can i do device to device connection in android using sets of api which can be :
1.Bluetooth - whose APIs are not currently available.
2.gtalkservice - removed from sdk1.0 3.wifi - I dont knw how to connect 2 devices using wifi apis . I have asked about wifi because we have developed a game on iphone which used wifi connection for multiplayer stuff.
Or is there any other apis which can be used for implementation of multiplayer in game ?
How do I map the device Y axis to the screen Y axis?I can't figure this out.I'm the developer of Tricorder, and I'm trying to make it so that the accelerometer and magnetometer indicators I draw always point in the right direction.On the G1 phone with the slider closed, all is well.But when I open the slider, I end up showing that gravity is pulling me to the left (if the phone is held with the display vertical).So, I know that the device, and hence sensor, Y axis is always in the direction of the earpiece; and the screen Y axis changes when I open the slider.And I know that I can use remapCoordinateSystem() to change the device axes to match the screen axes.But where do I find out what the device's orientation is?In other words, how do I compute the correct values for the X and Y parameters to remapCoordinateSystem()?
Configuration.orientation seems quite useless.Suppose it is set to LANDSCAPE.What does this mean?Does it mean a device which is "naturally" portrait (i.e. the sensor Y axis points to the narrow end), and which has been turned into landscape mode?If so, which way was it turned?Or does it mean a device which is naturally landscape?In other words, LANDSCAPE could mean that the screen axis is off from the sensor axis by +90, 0, OR -90 degrees.Not much help.So how do I do this?Obviously I want my app to work on all devices, not just the G1 phone.
I have a standalone GPS enabled data recorder in my car that can function as either a USB host or device. (Its a class 0x00h USB device). I currently connect to it via a WM 6.5 app running on my Palm Treo 750. I would like to port my WM 6.5 app to an Android phone. (I don't have a specific Android phone in mind, I would like it to be as generic as possible).Replicating the GUI is not that difficult, but I am having trouble getting started on the USB communication. I'd appreciate it if someone could point me towards an example, or the appropriate tutorial.

I want to use my iPod as my media player but I'd like to be able to control music from my Nexus (only basic controls).
Is there an app on either device that allows this? I know tsk skipping can be done by some Bluetooth headphones so I'm hoping there's a way to make iOS accept command from my Nexus
I'm using the android plugin for eclipse, and when I try to run my program using a real device through the android device chooser, my phone is not listed as a device. I have updated eclipse and all of the android packages, but it still isn't showing up. My phone is running 1.6, which is also the target version listed in the eclipse project.Also, the reason I decided to try testing on a real device is because the emulator doesn't seem to be working right anymore when I run my project. The emulator launches, but the program never does. Any ideas?(using windows 7/t-mobile mytouch 3g)

I have an HTC and the battery life isn't all that great to begin with. I always charge the phone at night when I sleep. What I want to know is if this is ok to leave it on the charger at night for that amount of time?Also, when the phone is getting pretty low on battery I plug it in before the warning comes on to charge. Is this bad? But no matter what I charge the phone at night even if it was recharged at some point during the day. Will this ruin the battery?

View 7 Replies View RelatedI want to install a USB charging port in my car similar to this. Before I disassemble the cig lighter adapter I have and put it inside the console, I want to make sure that it's one that can provide a full charge, not just a trickle. I'd read that the trick is to get one rated at 1000mA which I did, but I've also read that some charger with that rating still can't provide more than a trickle charge. Short of plugging in my phone to that charger and using it for a while to see how quickly it charges, is there any way to see if the phone is getting a trickle or full charge?
