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.

I want to show the direction on the screen that phone is facing.
For example:
0
|- []
|_
South --- North
In the above diagram the phone would display "North". Since the user (the stick with 0 for his head) is holding out the phone (the [] in the diagram) pointing north.
I found this example. I understand what it's doing except it seems to calculate yaw, pitch, roll, and inclination. What are those and how would I use them to simply find which way the phone is pointing?
Also this android documentation mentions X, Y, and Z axises but I don't see anywhere that says how those axises correspond to the phone? Is Z going from the bottom of the phone to the top?
Is there an app which needs a code to unlock the phone instead of the swiping finger method?

All i found about GPS is that it just tells the location of the device, how do one get the direction where camera is pointing with GPS enabled phone?
For example, I need to see the camera api and work out which direction the camera is pointing. So that I can see the direction I'm viewing. In the other word, it is work like a compass.
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....
View 3 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.

Desired Result:-
When the keyboard popps up upon clicking the EditText, ONLY the EditText scrolls up while the rest of the screen remains static as it is. Is this possible? If yes how?
I 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.
I've decided to keep my droid and not get the incredible. I'm still within my 30 day return, but i feel the droid is and can be a better phone overall. My droid has 2.1 and basically stock. I'm looking to gain a little more speed out of my droid for right now. I'm not looking for some crazy root just one that speeds it up nicely. Can anyone point this newb in the right direction?

Download the JDK and install that.
After you're done installing that, go to Android SDK | Android Developers

View 6 Replies View RelatedI've been playing with the data given by the accelerometer,trying to work out how I can gauge a shake from front to back or side to side. This all seems straightforward enough.But I'd love to know the direction of the shake. So, if the user is shaking backwards and forwards, I want to know if the device is moving away from the user, or back towards him/her. I can't find any way of telling this.

View 4 Replies View RelatedScrolling on an Android phone makes sense because it's like you're physically sliding the page upwards. However, now that I'm used to doing that, when I get on my laptop and start to scroll with my touchpad, sometimes I find myself scrolling the wrong direction. On a touchpad you drag downwards to go down on the page, or to slide the page upwards. So it's backwards from the motion you would make on your phone.
View 17 Replies View RelatedI'm trying to create a compass for my application BUT the difference is that, instead of having a line always pointing to north, I want this line to point for a specific point. I've been trying dozens of algorithms and nothing works. I've finally found one that points me exactlly to the point I want. But it doesn't move if I change the position of the device which is my objective. Basically, what I want is that no matter the direction I'm using my device. The line always point me to the point (picLatitude,picLongitude). I understood that for the line to move, I can't use static variables. I need to use the values offered by the onSensorChanged(SensorEvent event). This are the data I have available:
event.values[0]: azimuth, rotation around the Z axis (device in relation to north, 0º) event.values[1]: pitch, rotation around the X axis event.values[2]: roll, rotation around the Y axis mLatitude: device current latitude got from GPS (variable) mLongitude: device current longitude got from GPS (variable) picLatitude: static picture latitude established previously picLongitude: static picture longitude established previously distance: distance in Km from device to the picture calculated previously
And this the formula that works correct, and gives me the correct angle. (But it doesn't use any of the Sensor Data so the line Compass doesn't move):
double dLong = picLongitude - mLongitude; double y = (Math.sin(dLong) *
Math.cos(picLatitude)); double x = (Math.cos(mLatitude) * Math.sin(picLatitude) - Math.sin(mLatitude)*Math.cos(picLatitude)*Math.cos(dLong)); double angleDegreesWrongRange = Math.abs(Math.toDegrees(Math.atan2(y, x))); float angleDegrees = (float) ((angleDegreesWrongRange+360) % 360);
myCompass.updateDirection(angleDegrees);
I got this "bearing" formula from this website: http://www.movable-type.co.uk/scripts/latlong.html. I've try adding, subtracting, the azimuth.. I've tried with the others, seriously at this point I'm just demoralized.

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 see in all of the videos that they use their index finger but that just seems so awkward, so I use my thumbs. Has everyone just gotten used to using their index finger or do you use your thumbs as well?
