In one of my application, there are multiple Activity(s),
Mostly all activities are configured to be in Landscape orientation by providing android:screenOrientation="sensorLandscape" for each activity
in android manifest file. But one of the activity called 'MyDashBoardActivity' changes orientation to Portrait automatically, when that Activity starts in one of my Android device, but it works fine (Loads in Landscape orientation as expected) in other devices.
How can troubleshoot this issue.
remove this android:screenOrientation="sensorLandscape"
And write In your onCreate :
after setContentView();
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
Try myActivity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
or
<activity android:screenOrientation="landscape" android:configChanges="orientation|keyboardHidden" android:name="MyDashBoardActivity"/>

I have a problem to lock the orientation of my app in portrait mode. I added android:screenOrientation="portrait" and android:configChanges="orientation" to my Manifest. Moreover, I added setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT) in the onCreate(...) of my MainActivity. The MainActivity is extended by AppCompatActivity. At any time, it works, so you never see your app in the landscape orientation, except when you install it for the first time on your device. Then it is possible to change between landscape and portrait orientation. Does anybody know why this happens? Thank you in advance.
Don't apply the orientation to the application element, instead you should apply the attribute to the activity element, and you must also set configChanges as noted below.
Example:
<activity
android:screenOrientation="portrait"
android:configChanges="orientation|keyboardHidden">
</activity>
This is applied in the manifest file AndroidManifest.xml.
I'm currently developing an app, in which phones have forced portrait mode, while tablets support portrait mode as well as landscape mode. Some pages the layouts have respective landscape versions in the layout-land folder.
The problem
While using the app on a phone (so portrait only) and when autorotate on the phone is enabled, the landscape layout file gets loaded while the app is displayed as portrait mode.
When does this occur
To recreate this behaviour I open an activity and rotate the device. Then when I navigate to another activity, or close and open the application, the landscape layout gets loaded.
Method of forcing portrait mode
To force portrait mode on phones, I call
setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
in my BaseActivity onCreate method.
Other details
targetSdkVersion: 26
using support library 26.0.0
Thank you for helping!
Edit 1:
Unfortunately using (a combination of) the following settings in the manifest file gives the same behaviour.
android:screenOrientation="sensorPortrait"
android:screenOrientation="portrait"
android:configChanges="orientation"
Edit 2:
I've now tested on multiple devices (emulator, One plus, Motorola, Samsung and some more) and this oddity only happens on a Samsung A5 (api 23) for me.
Is other Activities are also have that code?
I meant, other Activity that doesn't extends BaseActivity?
I would prefer to set in AndroidManifest.xml file in each activity tag like >> android:screenOrientation="portrait"
add this line android:screenOrientation="portrait" in your project manifest file inside activity. Hope it work well.
Try this
<activity
android:name=".Activity"
android:configChanges="orientation|keyboardHidden|screenSize"
android:label="#string/title_activity_test_edit"
android:screenOrientation="sensorPortrait"
android:theme="#style/Theme.DesignDemo"
android:windowSoftInputMode="stateAlwaysHidden" />
Portrait orientation, but can be either normal or reverse portrait based on the device sensor.

As you mentioned,
phones have forced portrait mode, while tablets support portrait mode
as well as landscape mode
Set screen orientation in manifest will not work.
Use layout-land-sw600dp, layout-land-sw720dp folders for landscape view for tablets. Also please take a look at this SO thread
I want my android studio app to be landscape only, but to switch orientation when the phone is rotated.
This means that when u flip the phone 180°, it will still be landscape but will flip sides. Like the clash of clans game.
You should add the sensorLandscape screenOrientation tag to your activity in the android manifest file and you should be good to go.
android:screenOrientation="sensorLandscape"
Make sure to add this to all the activities that you want to have in landscape mode.
All you need is to go to your AndroidManifest.xml file and under each Activity add the screen orientation tag and set it to sensorLandscape. Make sure you do it for all the other activities if you want them to be in landscape too.
For Example :
<activity
android:name=".MainActivity"
android:label="#string/title_MainActivity"
android:screenOrientation="sensorLandscape">
</activity>
I have read on many sites that all i need to do to make orientation change impossible on my android activity is just put this on my manifest:
<activity
android:name="com.karutakanji.ModoCasual"
android:label="#string/title_activity_tela_inicial_multiplayer"
android:screenOrientation="portrait"
android:configChanges="orientation|keyboardHidden" >
</activity>
But when i try my activity on Genymotion and a 2560 x 1600 device, the activity is still flipping to landscape orientation(it happens right at the start of the activity). Is there something else i need to do to make orientation change impossible to my activity? Is it only a Genymotion bug? What can i do?
There must be something else interfering with your manifest settings. I just tested it and I can't switch genymotion to landscape within my activity. If I start my activity when I am in landscape, genymotion directly changes to portrait as expected.
My guess: Whatever you do in your activity in onCreate() might interfere or overwrite it.
edit: the configChanges are not important. screenOrientation is the attribute you need to "restrict" it to that orientation.
solved it: it was just aGenymotion problem. I just had to emulate the device on fullscreen mode to make the bug disappear ^^
I want to run my application always in portrait mode. I searched and found the code below, then I added to manifest file.
android:configChanges="orientation"
android:screenOrientation="portrait"
but my application still chancing orientation when I press CRTL+F12 on AVD.
How can I force my application always run in portrait mode?
Ps: I tried the code reverse. (Second line first then first line)
Did you add that in the activity element, not the application element?
<activity
android:screenOrientation="portrait"
android:configChanges="orientation|keyboardHidden" >
</activity>
