Open a Web Site and Display Toast

December 5, 2013 - 2:31am #1

I need to show toast while image is recognize. I referred here: https://developer.vuforia.com/resources/dev-guide/open-web-site-and-display-toast-target-detection.

I replaced the java code. But where to replace the native code in ImageTargets.cpp. I put the below code:

// Did we find any trackables this frame?

for(int tIdx = 0; tIdx < state.getNumActiveTrackables(); tIdx++)
{
    // Get the trackable:
    const QCAR::Trackable* trackable = state.getActiveTrackable(tIdx);
    // Compare this trackable's id to a globally stored id
    // If this is a new trackable, find the displayMessage java method and
    // call it with the trackable's name
    if (trackable->getId() != lastTrackableId) {
        jstring js = env->NewStringUTF(trackable->getName());
        jclass javaClass = env->GetObjectClass(obj);
        jmethodID method = env->GetMethodID(javaClass, "displayMessage", "(Ljava/lang/String;)V");
        env->CallVoidMethod(obj, method, js);
        lastTrackableId = trackable->getId();
    }
 
 
I removed below code and replaced above code. But i got getId()!, getName(), etc method cannot resolved. where i did mistake. Where to replace the code. which code i need to remove from below?

 

  // Did we find any trackables this frame?

    for(int tIdx = 0; tIdx < state.getNumTrackableResults(); tIdx++)

    {

        // Get the trackable:

        const QCAR::TrackableResult* result = state.getTrackableResult(tIdx);

        // Choose the texture based on the target name:

        int textureIndex;

        if (strcmp(trackable.getName(), "chips") == 0)

        {

            textureIndex = 0;

        }

        else if (strcmp(trackable.getName(), "stones") == 0)

        {

            textureIndex = 1;

        }

        else

        {

            textureIndex = 2;

        }

 

        const Texture* const thisTexture = textures[textureIndex];
