I want my application to work in Portrait & reversePortrait mode .. In other words, I want it to work in portrait and make it rotatable 180 degrees!
I'm using the following code within <activity> tag of the MainActivity in the Manifest.
android:screenOrientation="sensorPortrait"
However, this seems to work only on Android 4.1.2 and backward.
It doesn't work on Android 4.2.2 and above!
I tried on different phones, the same result! How to solve it?
I'm aware of a typo error by Google that replaced sensorPortrait by sensorPortait at some point.
Not sure if that is your case, but depending on your targetApi, it might.
Use sensorPortait and see what happens at compilation.
This has been fixed in API 16.
