How to remotely control old android from new android
I have an older android that has HDMI connection and I can connect it to my TV, I want to be able to send video or music to it so it will play (so I don't have to buy another device like chromecast). Any ideas?
The android on the old device is pretty outdated and I cannot update it since hardware limitations, so keep it in mind when suggesting something it should be able to install on gingerbread with apk
