A while ago I reset a H10-2 that had a RK3386 Rockchip. I did this by means of the restore button on the motherboard. In doing so I'm having trouble finding a working print driver for the Seiko serial printer that is imbedded in the unit.
After some research I found a print proxy driver but it no longer works. After installing the app, it requests registration in order to use the print proxy. Now that's fine, but it does look like it has been abandoned and I can't register the app.
I have found an app on the stock image called POSFactory. This is basically a test software to run for engineers. Things like audio test, display test and so on. However, it also has print test and does some comprehensive print tests to the thermal printer, including a self test print.
I'm looking to get this printer working for the android system and wondered if anyone could advise me how to do this please.
Platform RK3368 (Octa-core 8)
Ram 2gb
Android 5.1.1

Hi there
the company that i work are developing an android based eco drive system. and i have been asked to do some research on it
the first obsticle we will face is actually connecting the device to the can bus. I have found a bluetooth however, im wondering wether this will work and wether there is a better way this can work
the system will have to work on almost any android device this is why i believe that the bluetooth system will be the best
also can any one direct me to a half decent Android dev site. i am a complete beginner with android development and really have no clue where to start and google is being proper vague
i hope someone can help :-S

Hey,
I have worked quite a bit with CANbus and I am aware that there are some good Bluetooth based solutions for linking to the vehicle.
Be aware though that CANbus is hit and miss with data and it is completely dependant on the manufacture what data is exposed to the CANbus, so certain vehicles may not have all the data you require.
As for Android development, best place to get started is the Androids own Reference, examples. I would post a link but I am new here, so just google Android Development and it'll be the top result.
Other than that I can only suggest googling/youtubing tutorials like with any other development.
Hi all
I've got a little food truck coming together and was looking at installing an ePoS.
There are many companies out there offering hardware and apps but not quite what im looking for.
I'd like to use an Android as a waiter/ cashier device and then send the order to the kitchen's Android device. Currently looking at using 2 Samsung S2 9.7 devices. The normal setup for all ePoS apps that I've found is that you can have a cashier/ waiter android but the order is sent to a BT printer or through a server to a standard EPSON (or similar) thermal paper printer.
i'm pretty sure that what i'm looking for is readily available but i'm not "feeling lucky" in my Google searches.
I don't want the added hardware like barcode scanners and card swipers. Just a couple of food orders from one tablet to the next.
If anyone can lead me in the right direction, I'd be truly grateful.

So I've got some old full image backups of my long dead Samsung phone, as well as a couple of others. I need to get some information off of them, however attempting to extract data from these images is turning out to be pretty complicated and to be quite honest, I don't know exactly what I'm looking for and so I'm looking to see if there is a way to simply restore these image files to an emulator. I'm aware that images are device specific but I don't know to what extent is the failure. Should I manage to "restore" an image and boot it, is android setup to just halt the moment it sees it's not the original hardware, or do certain functions just not work? And if any of you guys have any knowledge of QEMU and if it has the ability to emulate more than just system core architecture (x86, arm, etc...) but maybe it can emulate Samsung devices in a general way? I know this last question is a bit out of place, I'll be asking on the QEMU board as well, but just thought I'd toss it in here since it pertains.
Sorry for the total nub question, but since my case isn't device specific, I couldn't find a better place for it.

Hi, I'm an old Perl guy, who understands scripts and sockets, but I cannot quite understand what is RESTful API. I'm trying to make a whiteboard work, locally connected thru a nearby wifi-router. The app https://f-droid.org/en/packages/pro.oblivioncoding.fluffy_board/ says it can do it, but when I try to change from a Cloud connection to a local wifi network it asks for 2 addresses A Restful api url and websocket url. I guess from basics thyat those urls are one, for writing, the other for receiving? And the protocol is HTTP GET strings?
How do I setup such a thing on Android. I'm using Lineage OS 18.1 on a pair of old reliable Nexus 7's.
My motivation is that something recently caused me to mumble, and talking to friends is impossible. I wanted a realtime whiteboard shared with whomver I'm dealing with. I could just go with an acrylic story board, but I don't like the messy ink.

I've discovered that the number of camera app's that provide Clean HDMI out via USBC / a seperate monitor to be nearly non existant.
There's Filmic Pro, but at $150 a year subscription, it'd be cheaper to make my own for the 3 licenses I'd need.
I've made some basic Android apps previously, after studying at Uni, but I've not kept up with the API/scene.
Does anyone have any pointers on what the best angle of attack would be?
E.g. if there's a library recommendation with decent camera GUI functionality already, and what search terms to use to find the Android multi-screen API's for creating a second screen?
My searching resulted in finding multi-window support, and 'projecting/casting' support, which isn't what I was looking for.
