I'm a professional programmer, and I'm baffled. It seems that there is a whole "smartphone scene" and it's intimidating. I'm a Java expert and am comfortable with the Android SDK in Eclipse. However I'm completely baffled by the prospect of getting tethering to work on my Nexus One.
One thing that baffles me, for example, is the concept of a "ROM". Is there a ROM on the N1? I thought that ROMs haven't been used for 10 years. I was under the impression that the N1 is basically a little PC running Linux, which means that it should only have a bare minimum of a BIOS and everything else would be on "disk", or flash.
Another thing that baffles me is the concept of "rooting" the N1. It's running Android, which is an open-source mobile operating system. And, as far as I know, I have the permission to change all bits of the phone. Heck, that's part of the appeal! To say that you have to "root" your N1 is like saying that you have to "root" your Ubuntu box - it just doesn't make sense.
Complicating matters is the release of Froyo. I simply don't know enough to judge whether the actions required to upgrade the N1 to Froyo are compatible with the actions required to install a tethering app.
And that's the thing: I'm not just interested in installing tethering. I want to understand what I'm doing and why. I'd like to understand the options choose intelligently between them. There are so many resources online which are trying so hard to be helpful, but which don't really answer these simple questions.
I really appreciate your help.

search the correct forum for your phones model here on xda. some roms provide tethering preinstalled
check this thread for more info
http://forum.xda-developers.com/showthread.php?t=668090
while that targeted at g1, its the same concept. again search xda for the n1 section
Thanks for the link. However, I think I need a more conceptual introduction to the scene. The essential question is: what are the bits? On a PC you have:
1. BIOS
2. Disk
3. Peripheral firmware.
The disk is further broken down:
1. Bootloader
2. Operating system
3. Drivers
4. Applications
When you say ROM I assume you mean some combination of BIOS and Peripheral Firmware?
Hi guys,
I am new to app development and I have seen a lot of articles about apps that control the computer, but how would I actually go about making one? It doesn't need to be over Wifi either; it just has to be able to do basic keyboard actions over USB.

Bump. Anyone know where I could start?
Start with c+ and toss in a little Java coding.

You haven't even described what platform you're writing said app for.
Android apps are mostly Java... The rest, I dunno. MS is probably dotNET, apple is... objective C I think?
Sorry for the lack of information. All I know so far is I have Eclipse and ADT (I am developing an Android app). I understand XML and how to develop the GUI, but when it comes to making the app communicate with a computer, I don't have a clue where to begin or how to do it.
Any tips or guidelines on tools to use or how to start are appreciated.

By having a server program running on your computer which accepts data you send from your android.
If you want it to be difficult, do it over usb, the easy way would be wifi.
Check up on "sockets".
Thanks for the reply. The only problem is, I need it to have very fast response time. I would like it to be as similar to a USB keyboard as possible, so I don't think WiFi would work. What makes doing it over USB difficult?
Do you have the server side app already? what exactly are you trying to control on your computer?
It doesn't matter what I'm controlling, I just want to be able to get my app to send information that a server side program can take and be able to keyboard map.
So I'll need to code with C++ for the server side and java for the app itself?
Plus, from what I've read, I've learned that the Android platform doesn't support USB hosting. Is this true? I've seen ways around it but it seems pretty cryptic.

There already is one that is apart of the android market and you can even use it on another computer It's called Team viewer not sure if this would help you or not, but I liked it when I needed to use it.
You can do app development on a pc emeulator instead of your phone (if thats what your asking) and Google App Inventor is great, but servers are closing soon. So goodluck!
Yeah I would start looking up about c+, c++, and java coding.... goodluck
I appreciate the help. Ryan1918, I have used Teamviewer myself, but I am looking to develop more of a controller, as opposed to a remote desktop app.

Both can be done with java and if you program it right and the wifi signal is good you shouldnt have much of a delay.
It will be difficult to use the USB as a network interface for your application.
Using TCP/IP or UDP over Wifi will be much much easier.
I don't mean to ignore what you're saying about WiFi, but I strongly believe that for the market this app will be directed toward, USB will be necessary. I don't feel comfortable giving away my idea, but just know that my goal is to make the responsiveness virtually seamless if it is at all possible.
I will test it out with WiFi first, but in case I don't get the results I'm looking for, can you expand a little more on USB?
Will it only be hard for me on the developing side, or will the consumer have to also put in extra effort to get it to work over USB (installing other apps, rooting, etc.)? If I was to develop the app around USB, I would want it to be easy to set up if I did all the coding right.
From my continued research, I have found a few articles in the following links that might be leading me in the right direction:
http://developer.android.com/guide/topics/usb/accessory.html
http://developer.android.com/reference/android/hardware/usb/UsbManager.html
http://stackoverflow.com/questions/5848876/java-sockets-transmission-in-real-time
http://stackoverflow.com/questions/4762620/sending-simple-commands-from-android-through-usb
I don't have much expertise in the area, i just took a quick google shot at it and it showed from some forum posts and questions, that doing it through usb is not the easiest way.
Hello All,
I originally posted this question in the Android general forum but I didn't get any traction so I'm posting here in the hopes of finding some folks in the community with ideas for this project. I work for a not-for-profit children's hospital. The idea is to create a patient entertainment system (think the LodgeNET style systems in hotel rooms) using less expensive and more open hardware/software. We've purchased a few Android based set top boxes such as the EnjoyTV (I'd post the link but it won't let me) and have managed to get them configured the way we want.
The situation we're struggling with now is managing 200+ of these boxes out in the field. I have a few ideas but no one here really with the Android experience to bounce them off of.
Some thoughts:
- We would like to be able to completely reset the device to 'factory' defaults when patients leave rather than worry about locking down the devices too much.
- We would need the defaults to be our configuration, specific applications installed and perhaps even some hospital branding involved.
- I know I can reconfigure the ADB daemon on the device to listen on the ethernet port as opposed to USB.
- In doing so there is no security but I can handle security in the network layer using ACLs etc.
- I should then be able to use remote ADB commands to reset the device which I can script but what will get reset? Will my cusotmizations/apps go away? Will I have to compile a custom ROM?
- Is there a better direction to go in entirely?
Any help or even just a jab in the right directly would be GREATLY appreciated, both by myself and the kids who will benefit while they're here.
Hi,
I think you need MDM solution.
Ideally you might want to get Device admin rights and then reset it from remote easily.
I would like to create an IoT device by buying new, cheap android phones, strip them down and remove the screen, rebox into my own physical box, install a custom ROM without any bloatware (and that will boot without a screen!), and install my android app on the device to do stuff.
An example of a purpose for this could be a GPS tracker for a car. The box would be placed in the car, and record GPS and accelerometer readings, posting these readings back to a central server via the cellular network. (This is just a random example, so don't focus too much on the detail of this, but there are thousands of uses for a IoT board with the sensor, CPU, RAM, storage, and connectivity capabilities of a budget android smartphone)
The reason I want to use existing phones is that they are wonderful, mass produced, cheap devices with a variety of sensors I can use.
The reason I want to use Android is because it is because of the customization ability, and the mature development ecosystem.
To me, it seems an obvious thing to do, but I don't seem to be getting much joy trying to search for examples of this sort of thing (either here, or on the internet in general).
So some questions:
1. General thoughts? (Good idea? Am I missing some fundamental problem?)
2. What are the challenges of running Android without a screen connected?
3. Are there any custom ROMs you know of that specialize in this sort of thing?
(I've seen Google Brilo, but it still seems a bit early yet, and I really like the idea of just using the standard Android SDK to develop the app - and the abundance of help and information that comes with it)
Thanks!
I have a Tab S8 Ultra. I really like using DEX to emulate a computing environment. I have a small business and able to do just about everyting in need with it. However, it's not a 'true' laptop. Nevertheless, I want to cut ties with the laptop. There's one program I really need to do so. I have HGTV Home & Landscape Platimum Suite ver 3. It is, of course, windows based and my tablet is Android. Does anyone know of any available Drivers that will allow me to run it or is it even possible?
I just read an XDA contribution piece by Kyle Wiggers in January 2018 about "WINE - Compatability Layer for Windows. I'm really not sure if im on the right track here. However, this is the closest info I've found concering what I'd like to do. I'm wondering if there is any more development on this.
