I want to force two different orientations in my app. Only portrait for smartphones and only landscape for tablets. Since I must define it in the manifest for each activity, I can't figure out how to it programmatically!
I tried with setRequestedOrientation(int requestedOrientation) in my activity onCreate but it doesn't really start with my requested orientation. There is some dalay before my request orientation is set.
Develop two different versions each forcing it's own orientation and targeting specific screen sizes and distribute.

I have an Activity that is meant to be displayed in landscape. Ideally I want to support either direction of landscape. In my manifest I've set this on my Activity:
android:screenOrientation="sensorLandscape"
Which has worked fine in all my experience in the past. But this device seems to decide sometimes that portrait orientation is allowed. It will rotate to all 4 orientations (landscape/reverseLandscape, and portrait/reversePortrait).
If I set it like this:
android:screenOrientation="landscape"
it works correctly. Also if I disable screen rotation then it works correctly. However both of these options leave me with no reverseLandscape.
I've also tried requesting the orientation to be set in Java code:
setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE);
This does not seem to make any difference in the behavior.
Is this a known issue on Samsung devices? and is there any workaround to get the device to respect my sensorLandscape orientation setting?
I am developing an android application that supports multi-windows feature on Android 7.0.
I followed this guide on https://developer.android.com.
, imported sample project https://github.com/googlesamples/android-MultiWindowPlayground
I create a new resource named layout-land and did some testing. I recognized that landscape layout is inflated even though the device is in portrait mode.
Check out attached images.
How can I set portrait layout when device is in portrait mode.
Assume you have two screens. One is in landscape and one in portrait.
How can you say which one is in landscape and which one in portrait?
In portrait width of the screen is less than height.
And for landscape width of the screen is greater than height.
Agree?
So, here, when you enter multiwindow mode your app's window no longer fits screen - width is greater than height and it is considered as landscape.
That is why landscape layout resource is used.
There is no separate modifier for layout resource to be used in split-screen mode.
The only thing you can do to achieve portrait in your case is to remove layout-land.
Or you can create two separate layouts (without any modifiers such as -land) and in activity call activity.isInMultiWindowMode(); to choose corresponding layout you want to use.
I'm developing an android app for phones and tablets.
I want all of the devices to use portrait layout. I made a 'layout' folder for it. But, there are some X number of devices which are always in landscape mode. Probably, large tablets. So, I made a 'layout-land' folder too.
Which folder I need to add so that X amount devices will always display landscape layout only, while other devices will always display portrait layout?
Main requirement is to have only portrait layouts displayed. But, display Landscape layout when device itself is in landscape mode(default). I am talking about devices that display drawer in landscape mode, and the ones that open landscape layout of apps only.
Is this automatic?
I have android:screenOrientation="portrait" in manifest.
I can't test this as I don't have a tablet/large device.
I have already looked at this question and other similar questions.
Add the below line in your onCreate() method before setContentView()
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
I am developing an App, and I want whenever the user change the orientation of the device I display the current orientation of the device. Actually, I achieved this step, but when i rotate the device to be in REVERSE_PORTRAIT the screen does not obey the rotation, in other words, my screen can not be in the REVERSE_PORTRAIT.
In the manifest file, I changed the value of android:ScreenOrientation to be user, but still in the same problem, all the three orientations PORTRAIT, LANDSCAPE and REVERSE_LANDSCAPE are detectable EXCEPT REVERSE_PORTRAIT
How can I find a solution for this problem?
You can try to use fullSensor if you want every possible orientation
"fullSensor" The orientation is determined by the device orientation sensor for any of the 4 orientations. This is similar to "sensor" except this allows any of the 4 possible screen orientations, regardless of what the device will normally do (for example, some devices won't normally use reverse portrait or reverse landscape, but this enables those). Added in API level 9.
all the possible values for screenOrientation and some explanations are here :

I want to desing a GUI for android's tablet. By default i want to use landscape orientation of this application, so i placed the controls (text boxes, text views etc) accordingly, but when i change the orientation of tablet from landscape to portrait, whole GUI of activity gets distrubed. Can anybody guide/help me what is the best approach for designing of GUI in android such that controls appearance should remain correct in either orientation (portrait or landscape)? Thanks in advance.
You have to create another folder in the res directory called "layout-land". Put the layout file for landscape in this folder and the one for protrait mode in the normal "layout" folder. Both files must have the same name. Android will automatically chose the correct layout depending of the current orientation of the device.
Check the link below, it will provide all information about how to design an application to support multiple screens with different sizes and resolutions.
