I am developer tizen consumer tv web app.How should i rotate the screen (toggle orientation) by code.
Please help us in this.
Let me know if you need any further information.
Lock the screen with the lockOrientation() method.
The following code snippet demonstrates how to lock the screen to a specified orientation.
screen.lockOrientation("portrait-secondary");
The method accepts the following parameter values: portrait-primary, portrait-secondary, landscape-primary, landscape-secondary, portrait, and landscape.
Note:
When using the screen orientation lock:
When the portrait value is used to lock the orientation, the orientation can change between portrait-primary and portrait-secondary. The landscape value behaves similarly.
Depending on the browser, unlocking the screen orientation may have no visual effect.
For more follow this.
You can use this code for rotate the device form Landscape to portrait .
b2bapis.b2bcontrol.setMenuOrientation("DEGREE_90",onSuccessSettingMenuOrientation,onErrorSettingMenuOrientation);
b2bapis.b2bcontrol.setSourceOrientation("TV","DEGREE_90", onSuccessSettingOrientation, onErrorSettingOrientation);
Note: need to add privileges in config.xml

My flutter app only supports portrait mode.
However, on one screen user can take the pic using the camera plugin. Users can take the pic portrait mode or landscape mode(Without changing device orientation).
I want to display a rectangle overlay on top of the camera. So if I can detect the mobile is in landscape or portrait mode I can add x,y, height, width values according to the orientation.
I am not asking about the Orientation builder because my app only supports portrait mode.
I have read some articles about Gyrometer to detect the device orientation. But in flutter, I haven't found code examples.
I'm developing a game that runs on both mobile phones and tablets.
Currently I'm using only the Portrait orientation for all devices but the portrait orientation looks better on phones meanwhile landscape orientation looks better on tablets.
I set "Portrait" option in the Unity's Player Settings > Resolution and Presentation > Default Orientation but I would like to provide a landscape layout for tablets (without affecting phones).
How I can I do that? Is there any why to programmatically set the Screen orientation when the application starts?
You can try Screen.Orientation
In the Start (or Awake) method of a MonoBehaviour that is added to the stage call:
Screen.Orientation = ScreenOrientation.LandscapeRight
Now you just need to check if the device is tablet or phone, I don't know any way out of the box to do this, but you can check the aspect ratio and base your decision on this.
You can check the aspect ratio by getting Screen.width and Screen.height.
An iPad app can support inclusion of launch images in both orientations; presumably, if your app supports auto-rotation, then this would suggest to me that if the user launches an app while the device is in Landscape mode, then the Landscape launch image is used.
But in all the apps I've built and released, this has never been the case. Never once has the Landscape launch image appeared, only the Portrait. After loading, the app will auto-rotate to whatever orientation the device is in, but at launch, it assumes you are in Portrait. Always.
Why?
I have seen many other apps in the store that behave this way, but then there are some seem to always automatically know immediately at first launch, from that first launch image, that you are in Landscape, if that's the case.
How is this done?
iPhone supports only portrait images (http://developer.apple.com/library/ios/#documentation/userexperience/conceptual/mobilehig/IconsImages/IconsImages.html#//apple_ref/doc/uid/TP40006556-CH14-SW5)
Apps that don't support portrait orientations, provide the same portrait oriented image. For example, Angry birds on iPhone has the same portrait oriented image but the guys painted rotated graphics on it.
As it would turn out, the issue was due to leaving out the supported orientations in the plist file for the app. You can add these manually or just select them in the Target page. More details here:
How to get a landscape launch image to actually appear when launched?
I am developing one iphone app, and i want to support all orientations.
The problem is that I want the default.png to be launched in the proper way according to the orientation at start up. Can someone post some method or proper name for default images so that I can rotate it?
Basically there is a landscape "default" image only for iPad. in iPhone you should suplly only one in the main orientation of your app.
anyway, if you want to do that, there is a workaround posted in this question:
Auto-rotate the default application image according to current landscape mode
I am developing an application that is in landscape mode. I have Default.png with size 480x320.
But still when it launches the default image comes in portrait mode not in landscape mode.
However it should come according to the device oreintation.
If i take default.png with same size in allready rotated. then it comes as it was in rotated mode.
However it should come according to the device oreintation.
Please help me
There is an answer to question How to put Default.png in landscape mode? by #brentford that should help you.
There is also an article by John Muchow which outlines a different way one way to accomplish what you want to do.
Taken straight from here
"In iOS 3.2 and later, an iPad application can provide different launch images depending on whether the device is in a portrait or landscape configuration. To specify a launch image for a different orientation, you must add a special modifier string to the base file name of your standard launch image. Thus, the format of each file name becomes the following:
[basename][orientation_modifier][scale_modifier][device_modifier].png"
So in your example you could have:
Default-Landscape.png
Default-Portrait.png
(Default-Landscape#2x.png for iphone 4 and Default-Landscape~ipad.png for ipad and so forth...)
both have to be 320x480 and you'll have to ensure that your app's Info.plist contains all 4 UISupportedOrientation values (UIOrientationPortrait, UIOrientationLandscapeLeft etc etc). But see my above link for a better explanation.
I believe the splashscreen is loaded without checking for orientation.
Try to set UIInterfaceOrientation key in the info.plist file to UIInterfaceOrientationLandscapeLeft (iPhone home button will be on the left) or UIInterfaceOrientationLandscapeRight (home button on right).
