Samsung Tablets has screen settings for everyone app on device (Settings/Advanced features/Labs/Show apps in landscape). This setting may have different for some apps by default, usually App Default or App aspect ratio (img1). With App aspect ratio apps stay in Portrait mode when device is in Landscape mode (img2). I can't find any description of dependecies of this setting value.

Maybe someone know, what I need to change in AndroidManifest.xml, build.gradle or maybe Activity implementation to receive App Default as a default value?

Answer 1

Most apps which have locked the orientation, I believe, are doing it via the AndroidManifest.xml in the launcher activity by using the attribute android:screenOrientation, under the respective <activity> tag

The list which you're mentioning can be populated using ActivityInfo class' field screenOrientation.
