JMonkeyEngine integration with Google VR SDK

gvr-android-jme

JMonkeyEngine integration with Google Cardboard VR SDK 1.0 for Android http://developers.google.com/vr/android/

Works in the Android Emulator for x86

This work is baset on https://github.com/oak1980/gvr-android-sdk-jme and https://github.com/neph1/jme-cardboard-example . In includes libraries and the Treasurehunt sample from https://developers.google.com/vr/android/.

For information on JME see http://jmonkeyengine.org

How to get started?

There is no setup - just clone the repo, open in Android Studio and run the samples

When you are ready to create your own app you can copy 'sample-jme-startravel' module. You can also create a new Android module from scratch, just jake sure to copy the contents of build.gradle of the sample-jme-startravel sample.

How to run JME+GVR in the emulator

Make sure you are running on a x86_64 emulator Enter the settings of the emulator and change Graphics to "Software - GLES 2.0" in 'Emulated performance'. (tested on Ubuntu 16, Android 6.0 x86_64 emulator 27/9/2016)

Troubleshooting

UnsatisfiedLinkError: couldn't find "libgvrbase.so"

You need to exclude JME processor archtectures that are not supported by GVR. In build.gradle, add the following

defaultConfig {
    ...
    // Exclude architectures beyond those that are included in GVR to avoid
    // UnsatisfiedLinkError: couldn't find "libgvrbase.so"
    ndk {
        abiFilters "armeabi-v7a", "arm64-v8a", "x86"
    }
    ...
}

I need to modify something in the settings, which isnt exposed

Right now the only way I found (this is a really clumsy solution) is to override setSettings()

public class TestJaime extends SimpleApplication {

@Override
public void setSettings(AppSettings settings) {
    settings.setAudioRenderer(AppSettings.ANDROID_MEDIAPLAYER);
    super.setSettings(settings);
}

I can only see anything in the center - the objects disappear when not in the center

Culling is too aggressive in GVR - so disable it for now

rootNode.setCullHint(Spatial.CullHint.Never);

Textures are missing

Try to remove wrong path ("/") in Android Assetmanager:

assetManager.unregisterLocator("/", AndroidLocator.class);
assetManager.registerLocator("",AndroidLocator.class);

The image is rendering upside down

Im working on that one
