How to get Camera direction of GPS enabled phone?
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'm a bit new to Android but after searching on the Market, the web and this forum, I can't seem to find anything like this but I feel like it has to exist (or hopefully will soon). I'm looking for a camera application that can place the current compass direction on the image (and stamp the saved image with the direction). The tilt of the phone would be cool to have, too, but just the compass would be great. I did find an application that shows the compass direction on over top of a feed from the camera ("Reality + Compass" by Udell Enterprises).
I want something just like this, but with the ability to save the image. In case you're wondering, I'd like to use this for bettering the storm spotting community. A problem when people send in images of clouds/storms/tornadoes/etc is that you never know (1) where the picture was taken and (2) in what direction. Ideally GPS location could be added, too, but for now I just want the compass. (Other image services can handle the location part fine, like Twitter for Android/Twitpic.)

I wanna set the ADB_ENABLED and USB_MASS_STORAGE_ENABLED option automatically in my App.
so i add below statement in my App(Activity).
---------------------- Settings.Secure.putInt(getContentResolver(), Settings.Secure.ADB_ENABLED, 0);
or
Settings.Secure.putInt(getContentResolver(), Settings.Secure.ADB_ENABLED, 1); ----------------------
and add below statement in my App(manifest).
---------------------- .... </application> <uses-permission android:name="android.permission.WRITE_SETTINGS" /> <uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS" /> .... ----------------------
but some exception are occured in runtime like below.
---------------------- Uncaught hander: thread main exiting due to uncaught exception. java.lang.SecurityException: Permission denial: writing to secure settings requires android.permission.WRITE_SECURE_SETTINGS ... ----------------------
How i can use ADB_ENABLED and USB_MASS_STORAGE_ENABLED in my App?
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?
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?

View 3 Replies View RelatedHaving an issue where anytime I try to add a new contact manually for a new phone number or create it using the "create new contact" feature via an old text message by that phone number's owner, my phone automatically deletes it within seconds. This happens only when the sync settings under settings-->accounts & sync-->background information are enabled. The new contact gets deleted regardless whether I add the new contact BEFORE enabling sync or whether I add it WHILE sync is enabled.

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.

My current app flies in a sub activity when you flick-up. Problem is, it flies in horizontally from the right. I want it to fly in vertically from the bottom to match the flick direction.
