I'm working on my first Android Augmented Reality application. The application works pretty good if the ARActivity runs as the first class (android.intent.category.LAUNCHER) in the manifest file. But when I added a splash screen which means the ARActivity will be the second to run(android.intent.category.DEFAULT), the camera seems not detecting the marker. I believe the problem is all in the manifest file. Any suggestions ? Thanks
This is the manifest.xml
