Hi AlessandroB ,

So how do this in Unity ?

The problem is that you cannot completely avoid to have black screen (or otherwise splashscreen);

with the little tips that I provided you can reduce the time to a minimum, but you will still have to wait for a second or so before you can display the camera background image; that's because Vuforia requires a bit of time to complete initialization; during that time either you don't display anything (i.e. you get the back screen), or you can display a splashscreen like the samples do.

hey, it still there, even if i remove all the variable that contain "splashscreen" word it still shows nothing for a seconds.., exept in these codes:

mSplashScreenHandler = new Handler();
                mSplashScreenRunnable =
                    new Runnable() {
                        public void run()
                        {
                            // Hide the splash screen
                            mSplashScreenView.setVisibility(View.INVISIBLE);
                            
                            // Activate the renderer
                            mRenderer.mIsActive = true;
    
                            // Now add the GL surface view. It is important
                            // that the OpenGL ES surface view gets added
                            // BEFORE the camera is started and video
                            // background is configured.
                            addContentView(mGlView, new LayoutParams(
                                            LayoutParams.FILL_PARENT,
                                            LayoutParams.FILL_PARENT));
                            
                            addContentView(mOverlayView, new LayoutParams(
                                    LayoutParams.FILL_PARENT,
                                    LayoutParams.FILL_PARENT));
                            
                            // Start the camera:
                            updateApplicationStatus(APPSTATUS_CAMERA_RUNNING);
                        }
                };

i bring out mRenderer code until updateApplicationStatus to the outside of runnable, and remove the handler and the runnable.. where did i get wrong?

Hi,

that delay is due to the mSplashScreenHandler which launches a runnable with a certain delay; you should be able to get rid of it by changing the MIN_SPLASH_SCREEN_TIME variable to 0 (currently it is set to 2000)

thx for your reply, i have tried your post, i remove all the mSplashScreenView variable, but what happened to my app is: it still launch some kind of Splash Screen thing, it shows nothing for a seconds and then show the Camera View. well i think the Splash Screen is not fully disappear right? so what should i do next?

Ok, 

in 1.5 you have a mSplashScreenView variable in ImageTargets.java, just remove any reference to it in the code and it should disappear.

no, i mean, i didn't use vuforia 2.0, i used vuforia 1.5, and there is no ImageTargetsSplashScreen.java,

well in vuforia 1.5, the splash screen was handled by ImageTargets.java. it is different in vuforia 2.0 that has sparate class: ImageTargetsSplashScreen and ImageTargets.

i'm sorry if my post was out of topic, but i need help to remove this SplasScreen in vuforia 1.5..

Hi, the splashscreen is defined in the ImageTargetsSplashScreen.java file;

however, the visualization of the various activities (including the splash screen one) is controlled by the AndroidManifest.xml and by the startActivity() methods.

Check the manifest and the code (note: this is about Android programming, not really about Vuforia).

hi there, thx for your advice to see vuforia 2.0, now i can make menu in my app,

can i ask a question again? i made my app with vuforia 1.5, and from on of vuforia 2.0 project i learned how to add menu. there are Play, About, and Exit button on my menu, and when i press play, it will launch camera view like normaly, but the splash screen shown there. I know, it must be because i add Menu activities before CameraView (with the splash screen), but how can i delete this splash screen? what codes in ImageTargets.java i should delete?

Hi, you can create an Activity with your menu, and then for instance when you click Play, it will launch the AR activity;

have a look at the Image Targets sample in Vuforia 2.0, it contains multiple Activities.
