public class MainActivity extends VRActivity {

    @Override
    protected void onCreate(Bundle icicle) {
        init();
        super.onCreate(icicle);
    }

    // Pass this acitivty instance to native
    @SuppressWarnings("unused")
    public native void init();
}

// Example in jni.cpp
#include <wvr/wvr.h>

int main(int argc, char *argv[]) {
    return 0;
}

JNIEXPORT void JNICALL Java_com_htc_vr_samples_wvr_1hellovr_MainActivity_init(JNIEnv * env, jobject obj) {
    LOGI("register WVR main here.");
    WVR_RegisterMain(main);
