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?

I am working on an application where i will track the movement of the android device inside a building... suppose i display a map of the building in the android emulator... Now,i need to simulate the movement of the android device.... is there a way in which i can control the movement of the android device and see the real time movement of the device in the map ... like a dot moving in the map .... Is this possible to do using the android emulator? when i googled this requirement, i came across SensorSimulator...But,this software shows the acceleration,magnetic field and temperature values... It doesnt display the co-ordinate values....

Performs the work in run() and the draws in onDraw().Pretty simple.However, on a Droid it runs much faster than on a G1.What is a best practice for ensuring that the game runs at the same speed regardless of the device?

View 2 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 12 Replies View RelatedI'm working on an app that needs body movements as inputs. So basically I want to know if a person turns around completely (360°). If a the person does sthg happens inside the application. My problem for now is: How to figure out if a person turned around? I don't see an approach with gps as the person is not moving enough. So I thought about the compass or acceleration sensor but I have no clue how to manage that.

How to determine the speed of moving android device. Any pointers or hints.
View 3 Replies View RelatedI would like to detect shake movement in a service that is running in the background, even when the phone is not currently being used. Is it true that the only way to do this is to hold a wake lock? I suppose this would consume a lot of energy and drain the battery very fast.Is there no way to wake up the phone whenever a shake movement occurs? Maybe with the native sdk? I would imagine the accelerometer causing some kind of interrupt.
View 2 Replies View RelatedI know this is more of a general programming question, but my Android friends here have always been helpful. I am trying to make an image move from one part of the screen to a position the user touches, as a constant speed. I don't know the best way to go about doing this and the way I have been trying to get to work is taxing my brain too much.
I have been using geometry to calculate slope, then using Sin * movement speed to calculate the difference in X,Y coordinates.
This is the codecode...
The problem that I'm having is the image is veering way of course when traveling in Y heavy paths. When traveling horizontally it works almost perfect.
I know there is probably an easier way though I don't know how to use a lot of things (like OpenGLES) so if your advice is to use a different method please link a tutorial for that method if you know of one.
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.
Is it normal in all Cliqs for the screen-half to be very slightly moveable in the up-and-down vertical direction, both in open and closed position? I'm not talking about inward and outward, but rather up and down on the vertical y-axis like from the ear speaker at the top to the mouth mic at the bottom. And I'm only talking about a millimeter of very slight movement if you hold your thumb down firmly or grab it with two fingers and try to move it.
View 2 Replies View RelatedUsing Android, is it possible to automatically make your phone initiate a screen gesture (like a swipe across the screen) whenever you hit the power button, then proceed to turn off the phone? I know it's a very weird question, but I have my reasons.
I imagine it's possible with some type of app like Tasker, but I don't know if Tasker can initiate screen movements that imitate a finger moving across the screen in a point and direction of your choice.
I want to capture the finger movement direction on Android touch phone. If a user slides his finger in up/down/left/right direction, I want to capture this direction.
View 2 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?
