Application gets hanged or crashes when I upload all my 11 videos and simultaneous detection of 3 targets

I’m making a project in Unity 3D. It has eleven videos and two audio files.I have to ensure simultaneous detection of three image targets and they have to play on texture on single click and not going to full screen directly.But this is not possible as the application gets crashed and I have to compromise on the limit of files.Does anyone have a solution for this??Please help

The solution is to shift to a cloud database instead of device database in Vuforia. In this way all the image targets and videos will stay on a cloud and the application size reduces considerably
