Problem with screenOrientation on Android and other plugins

August 12, 2014 - 1:39am #1
Hello everyone,
We have a screenOrientation problem with our Unity Android application
It seems when we stay in the Unity context, the auto-rotation is correctly managed, but when we start others plugins activitys (uniwebview, facebook etc...), they didn't receive the auto-rotate event correctly. Sometimes, they are turned, but not correctly resized.
Taking the sample of the uniwebview plugin. The auto-rotation is correctly managed when this plugin is the main activity without vuforia. But when we use vuforia and so, QCARPlayerNativeActivity become the main activity, the container of the webview is rotated but not correctly resized.
This plugin includes source-code, so we tried to modify it. Our UniWebView activity (called AndroidPlugin) extends now QCARPlayerNativeActivity (and so no more UnityPlayerNativeActivity), but the matter stay the same... the container of the webview is rotated but not correctly resized.
We have tried too, to set the value of the attribute android:screenOrientation to fullSensor for the QCARPlayerNativeActivity, but something during the build process, seems cancel this change and  reset it automatically to the sensor value.
What can we do to correctly apply the auto-rotation to these type of plugin ?
Our configuration is the next :
-Vuforia vuforia-unity-android-ios-3-0-9. 
-Unity 4.5.2
-Minimum API Android 2.3.1
-Our default orientation is defined to Auto-Rotation in the Android Build Settings

Does it really an error or only a warning ? 

It seems to me that I have exactly the same warning with current release of Vuforia since 4.5.x Unity release, but it doesn't prevent my apps to correctly work.

Ohhh sorry, we have fixed our problem !

In fact, the process we have declared upper is correct. The only last thing to do is to change the main activity in the manifest.

So now, our main activity is not QCARPlayerNativeActivity but the AndroidPlugin activity of the uniwebview plugin. And it perfeclty works (Vuforia is always start at the begining, and the webview recieve correctly auto rotation informations) !
