Android unable to cast using SPMC to Chromecast?

Hello Guys,

I have uninstalled KODI for Android and at every attempt receive the
error unfortunately kodi has stopped? I then found SPMC for android in the
google play store and it will not cast automatically, when playing the video?

Is there something special needed to set up SPMC to use chromecast?

Ideas, please.

Regards,
George.
