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 The android on the old device is pretty outdated and I cannot update it since hardware limitations, so keep it in mind when suggesting something it should be able to install on gingerbread with apk
Here is one idea - use VLC Remote app (not tested):
Let us know if this worked :)
Here is another app that is supposedly compatible with GingerBread:
Access any Android phone or tablet remotely from your desktop computer or from another mobile device.
Also, VNC is one of the most popular cross-platform Remote Screen Sharing / Remote desktop protocols, so I just have googled "VNC Server for Android" and I've seen 2 apps but they both need ROOT access (on your old Android). Need to google "VNC Server for Android without rooting" or so
The idea is simple:
Here is an article that might be useful, they talk specifically as controlling another decice used as HDMI player, similar to what you want:
Link to Google Play, it does not need root
It uses Bluetooth to communicate with other Android device. Imagine a setup where you have an Android tablet connected to your HDTV via HDMI. In this setup, the tablet would serve as your media player. You need a remote control to use for your media player (i.e., your tablet) That’s where Tablet Remote comes into play. If you have a second Android device, you can use it as a remote control for managing your other device.
Here’s how it works:
Once the two devices are paired, you can now start controlling the receiver device. To do that, tap the Remote button on the controller device. You will be taken to a screen with playback control buttons that you can use for remotely controlling the receiver device.
I would personally still prefer the universal solution i.e. the VNC Server / Client solution. With this app, UI looks somewhat limited:
Hi Josef, please DO NOT blindly copy-paste from other websites http://www.androidauthority.com/how-to-phone-tablet-to-control-another-android-via-bluetooth-41969/
This will result into Google viewing our website (BitExperts) as a lower quality website with hight ratio of duplicate content.
Also, while copying, you have lost the link to the app in Google Play, which makes it even worse.
Anyways, I am going to senf $0.20 to you b/c that app looks like something that could help Boris with his problem. I will also edit your answer to add a link and add some writing so it does not look like a duplicate content
