Android :: Device Orientation / Mapping Device Y To Screen Y

Oct 30, 2009

How do I map the device Y axis to the screen Y axis?I can't figure this out.I'm the developer of Tricorder, and I'm trying to make it so that the accelerometer and magnetometer indicators I draw always point in the right direction.On the G1 phone with the slider closed, all is well.But when I open the slider, I end up showing that gravity is pulling me to the left (if the phone is held with the display vertical).So, I know that the device, and hence sensor, Y axis is always in the direction of the earpiece; and the screen Y axis changes when I open the slider.And I know that I can use remapCoordinateSystem() to change the device axes to match the screen axes.But where do I find out what the device's orientation is?In other words, how do I compute the correct values for the X and Y parameters to remapCoordinateSystem()?

Configuration.orientation seems quite useless.Suppose it is set to LANDSCAPE.What does this mean?Does it mean a device which is "naturally" portrait (i.e. the sensor Y axis points to the narrow end), and which has been turned into landscape mode?If so, which way was it turned?Or does it mean a device which is naturally landscape?In other words, LANDSCAPE could mean that the screen axis is off from the sensor axis by +90, 0, OR -90 degrees.Not much help.So how do I do this?Obviously I want my app to work on all devices, not just the G1 phone.

Android :: Getting Orientation Of Device

Dec 18, 2009

I have a camera preview activity, which is forced to stay in landscape mode.Is there a way I can tell the current orientation of the phone (not the screen orientation).Basically I want to know if the user is holding the phone in portrait mode, or in landscape mode, so I can rotate the output captured bitmap correctly (right now it just always outputs in landscape mode).

Android :: Default Orientation Of Device

Mar 21, 2010

How can i get the default orientation of a Android device.DROID has portrait as the default orientation whereas many of the android tablets have landscape as the default orientation. I want to determine the default orientation of a android device through an OS call and this orientation should be independent of the device position/ rotation.I will be of great help if somebody can suggest a mechanism to achieve the same.

Change Orientation At Run Time

May 14, 2014

I am new to Android development and in general mobile phone app development. I am trying to make an app which uses jpeg images as background. What should my image resolution be for it to be full screen? (eg. 1920x1080, 1280x720, 640x480, etc) Is it device specific?

I read about the resources and how you can place resources in 'drawable' folders and then Android selects the best match. But does it adjust the resolution when you change orientation at run time (tilt device)? Is there a setting in the manifest file for this? I set android:screen Orientation= "land scape" in the activity. Also does it crop the image if it is too large or adjusts it to fit on the screen?

Android :: App That Auto-reboots Device On Set Day/time

Jul 27, 2010

For the second time in a month I had to 'fix' text messaging by shutting my Droid Incredible down and rebooting. This was Verizon's suggestion.

I'm thinking an auto-reboot app, set up to reboot the DINC once a week, or even nightly, might be a smart thing to install.

Is there an auto-reboot app out there?

General :: Android Device Freezing All The Time

Feb 13, 2012

Have been having issues with MyTouch 4G freezing. According to community area, minimum amount of available internal device space for Android device is 25 MB. This amount was first determined by Android to be for the G1 which only had 126 MB of internal device available space. My question is, with Android phones having more available space ie: MyTouch 4g 4GB ROM and 512 MB RAM, should the available internal phone storage be higher than 25MB in order to run properly? It would seem to me that if the phone had more available internal phone storage, the available space needs to be proportionally greater to run properly.

Android :: Orientation Change - Dialog Above Activity With Fixed Orientation

May 14, 2009

I have created an activity for my game which handles all orientation changes by itself and has a fixed "portrait" layout. Actually it uses the accelerometer and is rendered using 2D canvas methods. If the level has been completed I show up a highscore dialog in which the user can enter his name. The dialog is floating above the underlying level screen which gets blurred out nicely. This generally works.

Problem is that the dialog does not get rotated if the orientation of the phone changes. So even if the keyboard is exposed the dialog is shown in portrait mode instead of landscape. I have tried to use an activity with dialog theme instead but the behavior didn't change. After several tries it seems that I have found the reason for this: Once there's an activity with fixed orientation in the activity stack then all subsequent activities keep this orientation, too. They will not react on orientation changes anymore (e.g. if the keyboard gets exposed).

After upgrading to 1.5 SDK the described behavior changed a little bit. Now at subactivities indead react on orientation changes like expected. However, the need to have an opaque background! That means that neither dialogs nor activities with dialog theme will work. Those will stick with the orientation of the underlaying activity. So my workaround is to first start a sub-activity with an opaque black background. This activity then shows my highscore dialog on top. It looks quite okay but I wonder if there's a better solution? Is it possible to show a dialog above a fixed portrait or landscape activity which automatically adapts to orientation changes?

Android :: Working Of LocationListener() In Real Time On Device?

Feb 12, 2009

i need to know about the LocationListener() working in the real time. Does it expect the user(device) to move in order to update the current location details or it automatically updates when ever the gps is enabled? Another query is regarding the getLastKnownLocation(). When is that last known location will be lost and thus returns null... (in realtime).

Android :: Alternative To Having To Select Device Every Time I Run Droid Application?

Is there some way to have Eclipse NOT present the Android Device Chooser dialog every time I run the Android application I'm developing? I'm using a running Android device, not an AVD. There's got to be some place I can set my default device to be the Android device so that I don't have to double-click on the device entry in the ADC dialog everytime.

HTC Desire :: Actual Charging Time For New Device?

May 7, 2010

The quick start guide says 3 hours to charge, where as here.
HTC Desire - When I first receive my phone, do I need to charge the battery?
It states 8 hours. Which should I follow? Also, can I have it switched on while I charge so I can set it up? And I imagine I should let it fully discharge before charging it again, but how many times is this appropriate for? The first 2 or 3 or more times?

Android :: Using Orientation Sensor To Get 360 Orientation

Jul 17, 2009

I have a problem with working with the ORIENTATION values of the SensorManager. I would like to have some kind of 360-value which directly shows me if the phone is in normal portrait (0), landscape, portrait turned around (180) or anything in between. So I could have, for example, an arrow that points to the floor (like gravity would do with a plummet) all the time, no matter how I tilt (sidewards) the phone. I thought this would be easy, but I'm pretty confused at the moment.

First of all, the X value of the orientation-array seems to correspondent with how I turn the phone, BUT: if it's completely uprightly standing, this value is about 60 ... why not 0 (or 90, 180, 270), as I would expect?

Second: The value resets if I turn the phone and Android automatically changes screen orientation. So both in Portrait and in Landscape mode it will be sth. like 60 when the phone is in a 0 angel in real world. I set "android:screenOrientation" to "landscape" but this doesn't help anything :/

I want the app NOT to change orientation when I turn the phone, but I want it to get a continuous orientation value when I tilt the phone.

Android :: Network Provider For Location Updates In Android GPS Gives Device Time?

Aug 8, 2010

While using network provider for location updates, I found that it is the same time that I set on my device. Can it not be that provided by network as it goes when it is GPS. Or if network provider cannot provide time , then atleast location.getTime() should return 0 instead of device time. Is there any way to avoid device time, as I want to distinguish it.

Android :: GetFromLocationName Always Throws IOException First Time - But Is Successful Second Time With Same Input

May 29, 2009

My calls to getFromLocationName() always fail the "first" time I start my app. I catch the IOException which has reason:

Unable to parse response from server

Then I make a second call and it succeeds. Once things are "awake" all future calls to getFromLocationName() succeed, it's just that first one, and there is a ton of latency.

I haven't run this on a device yet, just in the emulator. This seems like a network problem, but it is so reproducible I'm thinking I'm not initializing something properly. I'm using Android SDK 1.1.

But I see the warning on document: http://developer.android.com/intl/zh-TW/reference/java/lang/System.ht... "This method shouldn't be used for measuring timeouts or other elapsed time measurements, as changing the system time can affect the results." So, if this method should not be used for measuring elapsed time, then what will be suitable?
