In the application I have some videos in an array and others that are loaded from a server, I also use gif images and other resources. I have already compressed the resources to see if I have no problems but when running the application on a mobile with less range, it closes with the memory error insufficient. I use a Samung s7 for tests with 4gb of ram and even so when changing activity makes it slow. Please Help me

you should not keep an array of videos in your application. Instead you can keep the paths and url to video files and load only one video at a time which is needed to be played. Also try to use image caching library such as Picasso or Glide, they will take care of memory problems for large images too.

My app consumes too much RAM, sometimes closed with java.lang.OutOfMemoryError:
