org.robolectric.shadows.ShadowSharedMemory

@Implements(value=android.os.SharedMemory.class,
            minSdk=27,
            isInAndroidSdk=false)
public class ShadowSharedMemory
extends java.lang.Object

This is not a faithful “shared” memory implementation. Since Robolectric tests only operate within a single process, this shadow just allocates an in-process memory chunk.
