The problem is that the names of your files start with number.
How the Android SDK uses file names to create corresponding variables in the file R.java
, if you use a name other than a valid Java identifier, the R.java
does not compile. The same goes for images.
Try changing the names of the videos to, for example, video_1.mp4
, video_2.mp4
etc..
Welcome to SOPT. Would like to [Edit] your post and add the code you are using, so we can analyze and suggest a change. Thank you.

It is also important to inform which error logcat, so we will have a bigger direction to find the solution.
