Motorola Droid :: Phone Charge At Certain Angle - Sbf Back To Stock

Jun 19, 2010

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

Android :: Do MapView Overlays Get Painted At Angle

Oct 9, 2009

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?

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?

Android :: How To Calculate Angle Between Line Defined By Two Points

Apr 20, 2010

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.

HTC EVO 4G :: Front-Facing Camera Angle

Jun 12, 2010

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.

HTC EVO 4G :: Any Charger With Wire At Right Angle To Plug?

Jun 14, 2010

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.

HTC Droid Eris :: Scroll-ball Doesn't Scroll Left Anymore

Feb 11, 2010

So everything is perfect about my Eris except that the scroll-ball doesn't scroll left anymore. This isn't the first time the problem came up. My last Eris had the same problem. It scrolls in every direction except which is kinda annoying as I use it alot more than I thought I would. Should I take it up with Verizon? It isn't a life or death situation but it makes editing sentences in texts a pain.

Android :: Composite Operations In Droid Canvas?

Mar 31, 2010

I'm just starting with Android development and I'm coming from JavaScript/HTML world so I'm currently investigating the possibilities of the Android SDK.

The HTML 5 canvas supports composite operations (See here).

Is this possible in an Android Canvas? I scanned the API of the Canvas class but couldn't find anything useful. I need at least the composite operation "source-in" or (if this isn't possible) "source-atop".

Android :: Way To Get Pixel Values From Droid Canvas

Jul 9, 2010

I'm currently writing an Android game using surfaceView. I've optimized the game as much as possible and it runs quite smoothly. However, I have collision detection incorporated which is a bit messy. I would like to do collision detection by reading pixels directly from the canvas. Is this possible to do? The closest to this that I have found was to attach a new bitmap to the canvas using setBitmap. Then when I drew to the canvas, the bitmap would be updated. Would this be the way to go?

General :: Google Maps Navigation Viewed At Angle?

Jul 25, 2012

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.

Samsung Vibrant :: Macro And Wide Angle Lens Attachment

Aug 20, 2010

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.)

Android :: Accelerometer / Orientation For Rolling Ball Code?

Mar 23, 2009

If I'm reading things right, the accelerometer measures physical forces (i.e. movement) and the orientation sensor gives the tilt of the handset. If you are coding a rolling ball type app which would you use? You could argue accelerometer, in which case you measure each delta force and apply it to your balls physics. Or just the orientation and compute the effects of gravity again on the ball but just using different physics. Is there a preference? Would any be more accurate than the other?
