Good Morning

howdy, Owen!

So i'm finding the tutorials a great help, i've been working through them, however i'm still unable to open up the app on my device

what OS are you running?

windows 7

that could be a problem

this was a Nexus One, right?

yes

I seem to recall there are driver issues with that combination

hmm ok

let's do this

pop open a Command Prompt

ok

cd into the tools/ directory in wherever you installed the SDK

and, with the Nexus One plugged in, run "adb devices" (sans quotes)

you should get something like:

the sdk would install in a .android folder?

it's a ZIP file, so I don't know where you unpacked it

there is an .android folder in your user area, but that

is not where the SDK is installed

ok

i've found it

what do you mean cd?

I mean the cd command

or chdir if you like to use the longer form

I'm guessing you haven't used the Command Prompt much on Windows machines

nope :)

i'm just googling it

i'll be there in a second

hmm

so i'm getting an error that it isn't a recognizable command

never mind

on a whim, in the Command Prompt, just type "adb devices" (sans quotes) and press <Enter>

yeah same thing

OK

it just isnt recognized

the problem is, I don't use Eclipse and don't own Windows 7

where did you install the SDK on your PC?

just a random folder

please tell me the random folder

its in my share folder

C:\Users\Owen Coutts\Downloads\android-sdk_r05-windows\android-sdk-windows

OK

type the following into the Command Prompt:

cd "C:\Users\Owen Coutts\Downloads\android-sdk_r05-windows\android-sdk-windows"

(and this time the quotes are important)

alright

now, type in:

cd tools

Yeah, it still isn't recognizing the command

ok

what command?

sorry i tried adb devices again

ok now in tools i'm getting the emulator thats on

but i don't see my nexus one

OK, we're getting somewhere

shut down your emulator

and unplug the device from the PC

alright

now, type in:

adb kill-server

then:

adb start-server

ok

now, plug the Nexus One back in, wait a couple of seconds, and try "adb devices" again

it doesn't show any devices now

OK

most likely, you have a driver issue

ok

unfortunately, I don't have great advice on how to fix it

you can try the steps shown here:

though they are for XP and Vista, not 7

hmm ok

since I haven't even *seen* 7 (I'm a Linux guy), I don't know how closely the Vista instructions will match what 7 gives you

maybe it would just be easier to vm into xp?

vista drivers have usually been ok for me

if your VM solution offers some form of USB pass-through, perhaps

I didn't have a problem getting my Nexus One to work on my Vista notebook, and so I have limited experience with Android device driver problems on Windows, let alone 7

yeah i mean i have everything setup here it seems to be workign fine

i guess i can't try an older version of the driver because it wouldn't have n1 support

sorry I couldn't be of greater help on this issue

no problem

thanks anyway

Hi Mark

howdy, Ethan!

how can I help you today?

Good to chat with you again. Remember me? I took the Android bootcamp in February in Atlanta.

yes, I remember you!

I have a few questions regarding android

fire away!

As I understand it, the Android stack is divided into the Linux Kernel, Libraries, Application Framework, Apps

I was able to find lice

lice?

I was able to find the license for the kernel (GPL)

the libraries are Apache license with some parts that are more restrictive licenses

most everything else is Apache Software License 2.0

including the app framework?

yes

i found some conflicting info saying that it's "close-source"

does this include the Android runtime?

also under Apache?

If by the "app framework" you mean the APIs and such that you write Android apps to, no, that is not closed source

I don't know what "the Android runtime" is, in your eyes

let's reverse the issue:

the only things that are NOT under Apache2 are...

...the kernel

...a few other libraries (e.g., bluez) that are also (L)GPL

...some drivers for some devices

...and some of the Google apps, such as the Market and Maps

everything else is Apache2

oh ok

they are explicitly trying to minimize (L)GPL components, out of concern that device manufacturers might not like it

some drivers and the Google apps are proprietary

so what is the control that Google has over the device manufacturers on customization of the stack...

you don't get the Market and such unless you pass compatibility

CDD and CTS are key

and are described on that site

you don't have to ship an Android device with the Market and such if you don't want

in that case, the compatibility stuff falls to "a really good idea" rather than "a must-have"

for example, if manufacturers were to add a new library (to the Libraries layer), or manager to the app framework. Do they have to get it approved by Google or contribute this back to Android community?

no and no

so long as it does not break compatibility, Google won't quibble

see the Evo 4G and its front-facing camera support

now, I am not a lawyer, nor do I play one on TV

:)

if i add a totally new functionality that is not part of the CDD, am I still free and clear from Google and contribution?

and without knowing all of the licenses involved in your library and where it attaches to Android, I cannot state conclusively that there aren't license issues

as far as I know, yes

however, that's a far better question for somebody at Google

perhaps the [android-porting] Google Group could help

but then i guess i'm on my own to support the new stuff in the next rev of Android

oh, yeah

cool

changing the topic a bit

i wanted to know if there's any inherent in the Android stack (besides) apps that tie you in to google services. I couldn't find anything so wanted to make sure...

Well, I suspect there's some stuff below the app level

for example, on some Android devices, you have to sign in with a Google account at activation time

however, I'm not a firmware guy, so I don't know exactly where the Google account stuff all plugs in

it is certainly possible to have devices sans Google accounts -- see the ARCHOS 5 Android tablet

however, I don't know if you can pass CDD/CTS

I haven't delved into CTS myself, since it's rather big

and I only recently skimmed the CDD document and forget what it said, if anything, on Google accounts

yeah i tried to read those docs and it's so long :)

particularly for me, since I'm not likely to be building any Android devices very soon

I don't have enough LEGO(R) bricks...

i think one of the use case i'm trying to answer would be if on the handset, without signing in to my google account, i launch a browser and go to Yahoo search. Will google still know about my search habit?

if by "search habit" you mean whether Google will record the search string, I sure hope not

after all, you don't have to use the standard Browser app

there's Opera Mini, and soon Mozilla Fennec

any last questions before I close this office hour?

just to summarize so I have it straight: ok so from what i understand, then modifications to the stack are permitted and doesn't require contribution (dependent on which libraries). you can do as much as you want as long as it satisfy CDD/CTS if you want marketplace support but support for future releases is on your own

generally speaking, yes

sweet

thanks Mark

the devil, of course, is in the details

you've really helped

no problem

have a great day!

thanks you too
