Just in my application I want to get the speed of the android device using the GPS, so I use the api of location.getspeed().
http://developer.android.com/reference/android/location/Location.html...
However all the speed I got is just incorrect and the values are very different from the actual one.

Imagine to have the device perpendicular to the table, in portrait. The Z axis is watching to you and the Y axis to the sky. I want to measure the device's movement speed when I rotate it on the X axis. How can i get it?

View 3 Replies View RelatedI just recently started using pdanet when my high speed internet connection at home was having issues. Oddly i found it to be very fast and work pretty flawlessly from my droid. My question is during the summer i have a 2nd home which has no option for high speed connections, but does get 3g Verizon. I mostly would use my laptop for reading emails and teaching online classes through my college. Has anyone on Verizon ever had issues using bandwidth through a tethered device as i described? I know there is this on going battle of whether our unlimited plans are truly unlimited or not. I would not use massive loads of data but i do not want to incur problems with my service either. Love to hear your opinions.
View 11 Replies View RelatedCan 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

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'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)

View 4 Replies View RelatedI have a static background image, and a foreground that needs to be animated. I tried a couple different approaches but the animation seemed choppy. One thing I did was having 2 different views, constantly calling invalidate() on the foreground view. Another was to have only 1 surfaceview, redrawing the background image and the foreground on each step of the animation.
While a surfaceview offers an optimal way to do heavy-duty animation, having to redraw the background every time kills the performance. Neither produced a smooth animation. What is the best way to perform this kind of animation - static background and animated foreground?
Is there a way of getting the speed at which the device is running?

Tinkering with the towers lately and I've been seeing sme 4G coverage here are my mobile speed test results I was surprised considering I've been reading about people saying its more like 3 and a half G with speeds not much greater than 3G I realize however that right now there's almost 0 congestion and bandwith will slow considerably however the froyo update should even that out So what are your speeds?
View 7 Replies View RelatedI have just started with development and would like to ask if Android's QEMU emulator uses any type of hardware acceleration.I made a simple Android program that extends the WebView activity and loads a webpage at start.That's all it does.It takes 35 seconds to cold start the emulator and acitivity from the Eclipse IDE. It takes 12 seconds to reload the acitivity when emulator is already up & running.Do you think these numbers are normal? Is there any possibility to speed up the emulation speed of QEMU?I can try to answer to this question myself. In the past, I used QEMU with KQEMU kernel module that remarkably boosted the emulation speed on X86 hardware. But Android runs on ARM CPU (not Intel or AMD CPU), so KQEMU module cannot be used here.My PC is Intel Core 2 Duo E6850 3.00GHz. 4GB RAM. Running Eclipse IDE 3.5 (Galileo) on 64 bit Ubuntu Linux 9.04.

Is there a way to determine connection speed? E.g. EDGE, 3G, etc.? I already know NetworkInfo.getType() will tell me Wifi or Mobile. I'm looking at Is this NetworkInfo.getSubtypeName(), but the function is undocumented.
View 2 Replies View RelatedCurrently, attempting to scroll when the text view has large amount of text makes the app completely unresponsive. It doesn't ANR, but it doesn't respond either. I've tried occasionally removing some text from the text view and removing some spans also, but it doesn't seem to help much. Any idea how to improve scrolling? It takes ages to scroll up or down. I also tried throttling touch events but it hasn't helped either.

View 4 Replies View RelatedApparently auto focus in a phone camera isn't all it's hyped up to be. To get faster performance (the time from pressing the shutter button to the picture being taken is usually slowed down by the camera trying to find focus in autofocus mode (and sometimes missing completely and giving up if the subject is dark or lack contrast). I'm not sure about all Android phones, but my Acer Liquid has a focus setting either 'infinity' or 'auto'. From what what I understand about photography, on a small lens such as on a camera phone, the DOF (Depth of Field) is very large, and when the focus is set to the hyperfocal length (the 'infinity' setting), everything from infinity to about 2.5 ft is in focus. I confirmed this with my phone (set focus to infinity, see what the closest thing that's in focus). So what this really means is for almost all regular picture-taking, it should be set to 'infinity' for faster performance, and only set to 'auto' when one needs to take pictures of objects closer than about 2.5 ft, like a 'macro' mode. So it would've actually made more sense if Android Camera app were to label the two settings '0-2.5 ft auto focus' and 2.5-infinity fixed focus'. If your camera has this setting, give it a try and see if it's snappier.
