Android as monitor without VNC?

[Matanya99]

I'm building a PiTop, and I'm having trouble getting my IRULU 10.1" eBay tablet (Android 5.1.1) to function as a monitor. I've followed this tutorial and others like it:
joshuawoehlke.com/android-raspberry-pi-display-over-usb/
but there are two things wrong with it.
1) it doesn't work
2)if it was to work, i would be unable to use the mouse and keyboard attached to the pi.

All i want to know is if there is some way to send ONLY the monitor image to the tablet. I just want a low power screen. No touch, no sound, no input. Just a monitor. Is there any way to do that? Using USB would be the best, but would some thing like an HDMI to MicroUSB adapter work? Something like this: http://www.walmart.com/ip/StarTech-micr ... about-item
I've tried so many VNC methods that I would hope there is some way to just do what I want. Thank you!
My setup is a RPi 3 (Rasbian Jessie), with IRULU 10.1" tablet I got for $20 on eBay (Android Lollypop, 5.1.1).

Hi there. With a rooted android tablet, there should be no trouble getting VNC working.

When you say "it doesn't work" that doesn't provide any information about what the problem is.

Using a normal vnc client on android: [urlhttps://play.google.com/store/apps/details?id=com.iiordanov.freebVNC&hl=en]bVNC[/url]

Using x11vnc on the Pi for a vnc server, and using either Bluetooth, 802.11, or USB tethering for a network connection should be all you need.

If it's the android you're having trouble with:
Download a terminal emulator for android, make sure you're rooted, and install busybox, or a Linux chroot on the android (so you can get access to more useful command line utilities like ifconfig, ip, route, etc. for setting up a network connection.

If it's the Pi you're having trouble with:
In that guide, ignore tightvncserver, and instead use x11vnc. I find x11vnc makes getting a server up and running way easier.

No, you can't send just the monitor image to the tablet without using VNC or something similar. The Tablet may have video out, but it is unlikely to have a video input. MicroUSB to HDMI cables are for certain devices that can somehow put out an HDMI signal on a microUSB connector in order to drive a proper screen with HDMI input. It won't work the other way round.

You appear to be following out of date tutorials ?


USB Tethering should work if you are using OTG (on the go) Cable and USB Tethering is enabled on your Android Device.

When you plug in the OTG Cable to both the RPi and Android Device, the Android Device should request what USB Mode you require, do you get this ???

Does the Pi3 have OTG, I thought it was only Zero and A+ range?

No the RPi 3B does not have OTG, but the Android Device may need an OTG Cable.


Further to my earlier reply I connected my Experia Android 4.4.2 Phone using the USB Charger cable to my RPi 3B.

The Android Phone has both WiFi & USB Tethering enabled.

Raspbian Jessie with Pixel DE Operating System sees the Android Phone as a Networking Device and assigns Raspbian an IP Address, so I can surf the WWW using the Phones WiFi Connection.

Therefore if I setup RealVNC Server in Raspbian and the RealVNC Viewer in Android, which I have not tried yet it should just work ??
