Android :: Accelerometer / Orientation For Rolling Ball Code?
Mar 23, 2009If 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?

Jan 5, 2010I have looked and looked and looked and I cant seem to find anything that helps me control the accelerometer more then either having it on or off.
Its a little picky, so I need help calibrating it as well as seeing if there is a way I can designate it to only work in certain programs. If there is no way to do that, is there a widget that will allow me to turn the accelerometer on/off that I can download (if so whats the app called in the marketplace)?
Android :: Is Orientation Sensor A Physical Sensor Different From Accelerometer?
Oct 30, 2009Or it's just some virtual sensor the uses the data provided by the accelerometer and the magnetic field sensor to calculate the orientation?

Jun 9, 2009I am developing a game. In which the user controls movement using the accelerometer. Sounds effects can also be enabled. However when laying the phone flat down and playing the game without the accelerometer gives nice 0,0,0 values. However when play WITH SOUNDS on, i get a buch of weird values: while the phone is NOT moving.
This is really a big bug that makes life hard for Game Developers. I tried to take an avarge of the last 5 values from the sensor.. but this is not enough.. The harder the sounds plays: the higher the weird sensor values. When using the headphones: almost no weird values. Seems that sounds interferes with the accelerometer sensor.
Android :: Screen Lock Turns Of Accelerometer
Apr 16, 2009Currently it seems that locking the screen automatically turns off the accelerometer. I looked around for quite a while and didnt find any solution for that. Is that intentional? It would be really helpful to know if this is how it is or if I just didnt find the solution for that so far.thank you for any help on that (and as I said, even "doesnt work right now/on purpose/.
View 5 Replies View RelatedAndroid :: Accelerometer Not Working When Screen Turns Off
Apr 13, 2010As I understand it, there seems to have been a change in the OS that prevents the accelerometer from running when the screen turns off and the phone CPU goes into its power saving state.Can this be confirmed?I have gotten around this by using a wake lock, but this is a much less than ideal solution as it drains a lot of battery.If the accelerometer was disabled in low power mode to save the battery, it may very well have the opposite effect in many cases, such as mine.A partial wake lock seems to be required to keep it running, which is obviously much worse than if just the accelerometer were running without the need for the wake lock.Are there any other workarounds anyone knows of to getting accelerometer values while the phone is in low power mode?Also, are there any plans to change this in future versions of the OS?If there are no plans to change this, I would definitely like to petition for this to be changed.

View 2 Replies View RelatedMotorola Milestone :: Manually Rotate Screen Or Keep / Fix Current Screen Orientation
May 29, 2010is it possible to manually rotate the screen or fix the current screen orientation (with a key/button)? because it really annoys me having taken portrait pictures that cannot be viewed (with the media gallery application) in a portrait fashion on the milestone. this is because it always rotates the portrait picture back to landscape when rotating the milestone from landscape to portrait. right now there is no way of properly viewing portrait pictures on the milestone other than tilting your head (holding the milestone landscape and tilting your head along).this cannot be the way it was intended to be, right? or do I have to get a different viewing software which allows you to choose screen orientation? is there such an app?

Jan 19, 2012I was wondering if there was any java code that will allow you to make sure each window in your app stays in portrait despite the user flipping the phone to landscape. I already tried inserting android:screenOrientation="portrait" into both my android manifest and into every single XML file I had but unfortunately only some stayed in portrait and others still flipped to landscape.

Android :: Live Wallpaper Screen Orientation
Sep 23, 2010I have a series of live wallpapers out and one major sticking point I have with a certain set is that when devices switch to Landscape, the wallpaper, which in most cases is an image designed to fit the screen in portrait mode, appears off center. What is the conventional way to detect the shift from portrait to landscape?
View 2 Replies View RelatedAndroid :: Threads And Screen Orientation Change
Aug 30, 2009In the following sequence of events:
1. Start a new thread (as a result of a button click - or similar).
2. User changes the screen orientation (causing the Activity that started the thread to be destroyed).
3. Thread finishes, and wants to do some dialog (or any UI) work. However, doing a showDialog, dismissDialog, ... will crash, as the thread it still referring to the old Activity.
This can be solved by updating the data in the thread to refer to the new Activity upon a screen orientation change.
However, couldn't the Android framework just forward any requests from a destroyed activity, to the newly created Activity, saving us developers of handling it ourselves?

Android :: OutOfMemoryError When Changing Screen Orientation
May 8, 2009I get an OutOfMemoryError every time i change the screen orientation and I am having a hard time finding the mistake...
The Activitie's view consists of an ImageView, two Buttons and a Spinner. I don't have static variables and can't imagine where i could leak a context.
Most of the times, the exception is thrown at setContentView (R.layout.upload); sometimes it goes fine until imgUpload.setImageURI(imageURI);
The images i am displaying are form the G1's camera, so about 500kb and 2048x1536pixels

Aug 30, 2010I am trying to display an image from a URL, which may be larger than the screen dimensions. I have it kind of working, but I would like it to scale to fit the screen, and I also have problems when the screen orientation changes. The image is tiny, and I would like it to scale its width to the screen as well. (In both cases, I would like the image to fill the screen width with scrollbars (if necessary for height).
Here is my ImageView:

Here is the java code which loads the image: (some error handling code removed for simplicity)

I have tried different settings for android:scaleType. I'm sorry if this question has been asked before. I've gone through a number of tutorials on the subject, but they don't seem to work for me. Not sure if it has anything to do with the way the image is loaded. (from the web instead of a local resource)
Another issue is that sometimes the image doesn't even load. There are no runtime errors, I just get nothing in the ImageView.
