The pointer of the entry function is set to associate with the runtime library.
-
WVR_EXPORT void WVR_RegisterMain(WVR_Main_t main)
Interface to register the main function.
When VM needs to load native library and call JNI_Onload, runtime expect the entry function of native application registed here via this API.
- Version
- API Level 1

How to use¶
Here is an example for the function:
// Example in MainActivity.java
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);
}
