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).

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.
I have set my deveiec property to landscape in manifest file android:screenOrientation="landscape" No at runtime when I am trying to get the current orientaion of device using Configuration and ActivityInfo classes. Its always giving me landscape mode even my device is in portrait mode. Please suggest if you have any method which gives device orientation info at runtime.

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.

View 2 Replies View RelatedI 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?
I understand how to force a specific orientation per activity in the android manifest. I would like to know if it is possible to allow the keyboard to change orientation even though the activity(the layout really) must remain unchanged.
View 1 Replies View RelatedI 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.
Can someone explain a couple of very simple concepts to me - I'm interested in mobile devices running android and how they are identified over networks. Some scenarios: Device is connected over WiFi - presumably the device has a standard IP address as with any host and can communicate with any other android host over TCP/IP (assuming it knows the participating device's IP? device is connected over bluetooth - how are devices identified in this case? device is connected over mobile operator's network - this is the one I'm interested in and confused by - is there anyway for two or more devices to discover each other and communicate via the mobile operator's network? How does a device communicate with a backend server in this scenario? In other words, how do apps and devices communicate when not connected to a WiFi network?

I have a standalone GPS enabled data recorder in my car that can function as either a USB host or device. (Its a class 0x00h USB device). I currently connect to it via a WM 6.5 app running on my Palm Treo 750. I would like to port my WM 6.5 app to an Android phone. (I don't have a specific Android phone in mind, I would like it to be as generic as possible).Replicating the GUI is not that difficult, but I am having trouble getting started on the USB communication. I'd appreciate it if someone could point me towards an example, or the appropriate tutorial.

I'm using the android plugin for eclipse, and when I try to run my program using a real device through the android device chooser, my phone is not listed as a device. I have updated eclipse and all of the android packages, but it still isn't showing up. My phone is running 1.6, which is also the target version listed in the eclipse project.Also, the reason I decided to try testing on a real device is because the emulator doesn't seem to be working right anymore when I run my project. The emulator launches, but the program never does. Any ideas?(using windows 7/t-mobile mytouch 3g)

View 7 Replies View RelatedI figured that I can have custom layout for each orientation just by making two folders layout-port and layout-land. So I put different views in these folders. Worked well.
Now, I have a webview in my activity and it reloads whenever there is any change in orientation. So to prevent that I put android:configChanges="orientation" in my manifest file.
After putting this the reloading stopped but the contents in the layout-port started getting selected for landscape mode as well.
i have a layout folder with 2 layouts. layout1 and layout2 i have another folder layout-land that has layout1 in it. i would like to be able to get to all the layouts so i could create a set of layout like this: {layout1, layout2, layout1(from layout-land folder)}is there any way i can use the existing android mechanisim to do that? if not, what would be the impact of creating my own definition of the layout folder (for example to have under the layout folder layout1, layout2 and layout_land1 and have my code do getOrientation to diffrentiate whcih one should be presented).
View 9 Replies View RelatedI've built an app widget a fairly simple one that draws an image inside a frame. (If that sounds familiar, that's because it's very similar to the built-in one, but it's a start to something else.)The RemoteView consists of little more than a FrameView and an ImageView. I have a second FrameView that may display or not depending on some certain state awareness.The Image updates on an Alarm schedule rather than the built-in mechanism so the user can adjust this value after installation. The image is set on the RemoteView using a drawable ID from included resources in the package. They've been resized to approximately a quarter of the screen size, but might still be scaled a little by the ImageView.All of this has been working fine. There is one issue that I've been unable to diagnose even the root of the problem.
After an orientation change when the home screen redraws, the ImageView doesn't always draw. The rest of the RemoteView does draw just as it was set during the most recent Update.The mystery is that the ImageView does, in fact, draw if the Alarm is currently set. If it's not currently set, it doesn't draw. Nothing else seems to affect whether it draws or not. It doesn't matter if the widget process is running or not, either (killing it via DDMS and then rotating has the same effect).This occurs in the emulator as well as the G1. During a rotate, the widget gets no update event at all.I could set it to listen for configuration changed broadcasts, but since it works in one of the cases, I suspect something else is going on and that's just an unnecessary piece of duct tape.
I have a webview and I am using android:configChanges="orientation" to restrain the webview from reloading everytime the orientation changes.I also have two different folders layout-port and layout-land to define the layouts for different orientations.If I use android:configChanges="orientation" then the above two folders are ignored. Can I have both working at the same time?
View 6 Replies View RelatedMy underlying actitvity is set to landscape orientation, but when I show the dialog, I'd like it to be in portrait (vertical) orientation.I set the orientation in my layout to be vertical but that didn't help. The Dialog class doesn't have a method for such a thing.
View 3 Replies View RelatedFrom the documentation regarding the android:configChanges='orientation' attribute of the activity tag in the manifest:
Using this attribute should be avoided and used only as a last-resort. Please read Handling Runtime Changes for more information about how to properly handle a restart due to a configuration change.
Why does it say this?
In the case of threads and networking requests via a service API library, a request could be made with a reference to the original Activity, and then an orientation change could occur, leaving the thread pointing to the old Activity.
While this can be fixed, it's tedious and ugly compared to just handling the configuration changes yourself.
Why should it be avoided?
I guess I should also ask: would this be an acceptable reason for doing the orientation configuration changes yourself?
I've got an activity which is always configured to be displayed in portrait mode (with android:screenOrientation="portrait"). I don't want it destroyed when an orientation change happens, so I have android:configChanges="orientation" for it.
However, it *does* needs to be aware of orientation changes, so I can update the content. Unfortunately it would appear that while I am being sent configuration change events, the orientation in the configuration claims it's always in portrait mode, presumably because that's what the activity is set to.
How can I have my activity be permanently in portrait mode and *also* receive the correct orientation change events as the phone is rotated?
I 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.
View 3 Replies View RelatedI need to have my view resize itself based on the orientation. After extensive googling (maybe i was using the wrong terms) I could find nothing telling me how to detect when the orientation was changed. Here is my layout file: how do I have it automatically resize itself? I want each item (the EditText and the WebView) to fill half the screen (not counting the title/notification bars). I set the height to absolute and not wrap_content because wrap_content defaults to 1 line for EditText and nothing for WebView. and fill_parent has the EditText on top of the WebView.

View 1 Replies View RelatedI currently have a TabHost with 3 tabs.The content of each tab is an activity. The first and second tab make HTTP connections.The first tab still uses the UI thread (which i'm changing) so it would explain the slow orientation change since it's creating a fresh activity and making all those connections again. What I don't understand is why if I am on say Tab 3 which makes no connections at all does changing the orientation take such a long time (up to 5 seconds).In playing around with the TabWidget I noticed something that may be related.
