Android VpnService protect socket that's stored in native code?

Question

I\'m writing a VPN application and the socket used for the VPN Connection is handled in my native C code, not in java. How do I use VpnService.protect() on that soc

Answer 1

I simply wanted verification that my processes was valid, after completing more testing I've verified that it works.

Example

// Native Code
int socket;

JNIEXPORT jint JNICALL
Java_com_my_package_Class_initializeSocket
(
    JNIEnv *env,
    jobject jobj
) {
    socket = socket(AF_INET, SOCK_DGRAM, 0);

    // . . . Handler other socket preparations 

    return (jint)socket;
}

---

// Java Code
public native int initializeSocket();

. . . 

int socket = initializeSocket();
this.protect(socket);
