initialize

Initializes EasyAR. Only after initialize is called, can other functions be called.

Android Only An Activity for content hosting need to be passed in for permission requests, recording, etc. It is equivalent to call loadLibraries, setupActivity and initializeKey.

initializeWithoutSoLibraryLoad

Android Only

Initializes EasyAR. Only after initialize is called, can other functions be called. It is equivalent to call setupActivity and initializeKey..

This method will not load EasyAR native libraries, make sure to load libraries by your own or using Engine.loadLibraries .

Java

public static boolean initializeWithoutSoLibraryLoad(android.app.@Nonnull Activity activity, java.lang.@Nonnull String key)

Kotlin

companion object fun initializeWithoutSoLibraryLoad(activity: android.app.Activity, key: String): Boolean

Android Only

Loads EasyAR Sense native libraries.

Java

public static void loadLibraries()

public static void loadLibraries(java.lang.@Nonnull String soLibraryDir)

Kotlin

companion object fun loadLibraries(): Unit

companion object fun loadLibraries(soLibraryDir: String): Unit

setupActivity

Android Only

Passes in an Activity for content hosting for permission requests, recording, etc.

Notice: When running Unity, you need to call setupActivity before calling the C# initialize method.

Java

public static boolean setupActivity(android.app.@Nonnull Activity activity)

Kotlin

companion object fun setupActivity(activity: android.app.Activity): Boolean

initializeKey

Android Only

Initializes the key.

Java

public static boolean initializeKey(java.lang.@Nonnull String key)
