Media Player doesn't work when launching on Android

Hi
I have made a texture and material out of a “Media Player” . It works properly on windows but when I launch it on android device for example instead of the material it shows a black material (No Material).Please help me get out of this trouble.
Thanks

this might be an issue with not having lights in the scene. try changing the material to be unlit and plug the texture sample into the emissive pin.
