Android :: Rotation Angle Of Entire Mobile Phone While Using
Oct 14, 2010
I'm working on an Android program for my research. It needs to find out the angle while user using my mobile phone. The angle here is like a rotation angle of entire mobile phone, not the widgets in layout.
I've tried keyword "angle" on
http://developer.android.com/reference/packages.html
And I found a method "onSensorChanged" under public interface SensorListener. But the description there is too hard to me to understand. Is it the function I want?

Well my Droid quit charging, the only time I can get it to charge is when I hold the charger into my phone at a certain angle, same thing I gotta do when I flash sbf with rsd lite onto my Droid. I'm gonna miss this thing. But hopefully, with warranty, I'll have a brand new one in my pocket by this evening. What's funny about it is, I'm planning on getting the Droid x when it comes out. Lol, so I guess I'll have a basically brand new Droid to get rid of when the time comes. Sent from my Droid using Tapatalk

I'm looking for an app that will search the entire contents of my phone. For example, I frequently need to look up a contact in my address book and I can't remember the name but I do know the city. Any tips, anyone?

Is there a possibility to query the hardware specs of the camera. I'm especially interested in the AOV "Angle of View"[ http://en.wikipedia.org/wiki/Angle_of_view].

I have an android application that I want to always be running in landscape mode.
I have the following code implemented to keep the app in landscape mode all the time:
inside my activity in the Application Manifest
android:screenOrientation="landscape"
This seems to launch and keep the application in landscape view for the whole duration of the application. Perfect!
However, if I have the app running on my HTC Aria (Android 2.1) and the phone locks, if I unlock the phone, I see the application for probably half a second and it's in portrait orientation and then quickly switches back to landscape mode. It is quite frustrating because all of my views are jumbled around and it looks unprofessional as you can imagine. This happens in both the emulator and on my real phone.
Does anyone know how to stop the application from temporarily rotating when the phone is unlocked?
I have tried overriding onConfigurationChanged() but with no success.
I have also tried putting setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); into the onResume() but the app still shows as the incorrect orientation for a split second when the phone is unlocked.

Is there any way we can rotate a video in Android (specially in Java layer) as it supports ino BREW or WM?
Also, how does the orientation change (portrait/landscape) is different than the video rotation?

I want to upload my music library or access the files directly from the computer from anywhere, including my phone for free. I have done some searching around and have only found Posner.com, but it doesn't let you play an entire playlist from your phone, only a single song at a time. Anybody have any ideas? Also, I hear people talking about gmote when I look around, but isn't that a remote control? Not a way to play the music on the phone, please someone correct me if I'm wrong.

When an overlay is put on a MapView, the shadow suggest that its at an angle and not flat on the map.
I have been creating scaled bitmaps to overlay on a mapview, but i am either geting the scale wrong or the overlay is being painted at a slight angle, sitting up a bit, rather then being flat to the map.
Does anyone know if this is true? and if so, is there a way to stop it painting at an angle or do you know the angle so i can compensate for it when creating the bitmapped overlay?

So I got my Eris on Wednesday and dropped it today and did I mess it up. It feel from about waste level, I'm 5'8 so it wasn't that high. I even slid my foot out to stop a direct hit to the ground which was successful. However this didn't help at all. The entire screen shattered but the phone still works. I know I should have a case for it but in the 9 years of having a cell phone this is the first one I dropped one. I was planning on getting one but haven't had the time to go out and get one yet.
Anyways I though the Eris had the gorilla glass that was basically unbreakable. It doesn't seem like a fall from waste hight, slowed down by my foot, onto the linoleum floor at the food store would destroy the screen. The cracks start at the corner and spider web through the whole screen. Everything I've read about people dropping the phone said it never broke. I am wondering if the screen might actually be defective, probably not but I'm grasping at straws to avoid the insurance deductible. Good thing I have insurance on the phone.

I'm currently developing a simple 2D game for Android. I have a stationary object that's situated in the center of the screen and I'm trying to get that object to rotate and point to the area on the screen that the user touches. I have the constant coordinates that represent the center of the screen and I can get the coordinates of the point that the user taps on. I'm using the formula outlined in this forum: How to get angle between two points?
-It says as follows "If you want the the angle between the line defined by these two points and the horizontal axis:
double angle = atan2(y2 - y1, x2 - x1) * 180 / PI;".
-I implemented this, but I think the fact the I'm working in screen coordinates is causing a miscalculation, since the Y-coordinate is reversed. I'm not sure if this is the right way to go about it, any other thoughts or suggestions are appreciated.

I've just been fooling with the front facing camera and I noticed something that maybe some of you can explain more thoroughly. When I have the camera held vertically, the alignment is great, but when I turn the phone horizontally the image has a funny angle. It is almost like the lens is angled to the right, which would mean that it is slightly angled down when held vertically. Am I just getting goofed up by the "mirror image" issue? This isn't a problem, but it does make self portraits while being horizontally held pretty weird.

Anyone know of a charger where the wire is at a right angle to the plug? In almost every case, there is too much tension on the cord when plugged in to keep it standing on the kickstand. Also, in the car, a right-angled charger would be useful for me. I found a right-angle auxiliary input for the stereo, and that helps some. Previously, I had one big plug coming straight out of the bottom, and another coming straight out of the top.

When using Google Maps Navigation, how do you get it so as you're following the directions the maps is viewed at and angle so you can see further ahead on the map. Also how do you have the screen/map turn as the car turns?
Right now it's just looking down and with no angle/tilt on the arrow and the orientation stays "north up" all the time. It used to do this.

Has anyone tried using the EVO 4G lens on their Galaxy S?
Macro Lens Attachment
It was mentioned that the diameter of the lens is 13 mm, which is about the diagonal length of the little square on our Galaxy S/Vibrant. (Captivate has a round lens, so you guys should be able to glue on the metal ring easily) So we might have a bit of problem attaching the metal ring that comes with the macro lens. I really do want a wide angle lens for my phone though. I can think of plenty of use for it. (I know about the DVD lens DIY, but I don't happen to have a old DVD-rom lying around at the moment.)

I can't seem to rotate properly an image on the entire screen. The problem is that when the image rotates, you can see the background in some areas. I want the image to fill the screen also when it rotates. Here is the layout.I start the animation in onResume. As I said, the image rotates but there are background areas when it does rotate. I've tried using images much bigger than the screen but still it doesn't do what I want. I don't care that outer regions of the image are not visible. I just want the rotation to fill the screen. I guess ImageView sets its width and height initially and then, when it rotates, it uses those dimensions. Is there a better way to do this?

What I am trying to do is simply copy over entire folder full of mp3 files onto sdcard within an app. I am doing this out of "assets" folder because raw folder does not allow mp3 files to be named the way I need them to. Here is what I dug up so far but not sure if this will work. I am lost.
InputStream ins = getResources().getAssets().open(""); int size = ins.available();
// Read the entire resource into a local byte buffer. byte[] buffer = new byte[size];
ins.read(buffer); ins.close(); FileOutputStream fos = new FileOutputStream("/sdcard/myfolder/");
fos.write(buffer); fos.close();

I have been trying to figure this out for some time now. Is there any way to load the entire Assets folder instead of having to code it for every single item? Also, once the images are read, is there a way to have another app (already installed on the device) grab that data? The intent is declared in the manifest and on it's own with the items in the res/ drawable it works fine but to have more then one option I'm using the assets folder with subdirectories. The user choses an option, that directory loads through another app already installed, if that makes sense.
