\n By providing folding feature information you can adapt your Unity code to move user interface elements away from the hinge, adapt gameplay for foldable devices, or even incorporate device features like the device hinge angle sensor in your user interactions.\n<\/p>\n
\n \n This blog post explains how to incorporate the latest Jetpack Window Manager package into a Unity project. These instructions are also available in the dual-screen developer documentation<\/a>.\n<\/p>\n \n To customize the relevant Android build files, go to Edit > Project Settings\u2026 > Player > (Android) > Publishing Settings<\/strong> and check these Build<\/strong> options:\n<\/p>\n \n \n This will place new items in the Project\u2019s Assets\/Plugins\/Android<\/strong> folder (plus a Java file that is added manually):\n<\/p>\n \n \n The purpose of each file is explained below:\n<\/p>\n \n Review the FoldablePlayerActivity sample code<\/a> for an example of how you can access Window Manager \u2013 you can copy this file directly into your game code<\/em>. Most apps will not need to access all the values available \u2013 just choose the information that works for your use case. The high-level features of the code are:\n<\/p>\n \n Thanks to Unity\u2019s native integration this file can be placed in the Assets\/Plugins\/Android<\/strong> folder, and it will be compiled as part of the Android build process (including the references to the UnityPlayerActivity class, as well as the libraries added to gradle). It\u2019s important that the AndroidManifest.xml<\/strong> file is updated to reference the new class (as shown above, and in the sample project).\n<\/p>\n \n To access the native API from C#, use the interop features of Unity to get the values set by Jetpack Window Manager. The example WindowManagerHelper.cs<\/a> shows how to use \n The static constructor for WindowManagerHelper caches a reference to the FoldablePlayerActivity in its constructor:\n<\/p>\n NOTE: the FoldablePlayerActivity is the \u201ccurrentActivity\u201d for the Unity app because we configured it in the AndroidManifest.xml<\/em>\n<\/p>\n \n Methods matching each of the different properties in Window Manager can then use the activity reference to retrieve information such as isSeparating, orientation, occlusionType, or the folding feature bounds. Here\u2019s an example method that retrieves one of the values from native Java code:\n<\/p>\n \n The sample duo-screenhelper<\/a> project is available on GitHub.\n<\/p>\n \n If you have any questions, or would like to tell us about your games, use the\u00a0feedback forum<\/a>\u00a0or message us on Twitter\u00a0@surfaceduodev<\/a>.\u00a0\n<\/p>\n \n Finally, please join us for our dual screen developer livestream<\/a> at 11am (Pacific time) each Friday \u2013 mark it in your calendar and check out the archives on YouTube<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":" Hello game developers!

**APIVERSION**<\/code> so that Unity can insert values from the project\u2019s configuration but allows for user-entered items as well. To include Jetpack Window Manager in the project, we need to add the following:\n dependencies {\r\n implementation \"androidx.window:window:1.0.0-beta02\"\r\n implementation \"androidx.window:window-java:1.0.0-beta02\"\r\n implementation \"org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.3.61\"\r\n implementation 'androidx.appcompat:appcompat:1.2.0'\r\n implementation 'androidx.core:core-ktx:1.3.2'\r\n }<\/pre>\n<\/li>\n**ADDITIONAL_PROPERTIES**<\/code>) but also allows for customization. For Jetpack Window Manager, we need to add the following line:\n android.useAndroidX = true<\/pre>\n<\/li>\n
<activity android:name>=\"com.microsoft.device.dualscreen.unity.FoldablePlayerActivity\"<\/pre>\n<\/li>\n
FoldablePlayerActivity.java<\/h2>\n
