programming ON my android phone (etc)

Greetings gentlefolks.
This forum has been an absolute godsend. I managed to get the latest JF os installed and as such am thoroughly enjoying my G1.
In the past, I had a Windows Mobile phone from HTC. One of my favorite applications on it was Pocket Scheme because it enabled me to write code ON my phone. I'd love to eventually spend time working on software FOR my G1, but right now I'm interested primarily in writing code while on the train, in line, etc.
As far as I know, Pocket Scheme is not available on the Android. I also came across Ruby for Android [2], but so far it force closes as soon as I open it.
So:
1. Are there any languages that are available for writing code on the android? Something with either an included editor AND repl (like Pocket Scheme) or even just an editor (?) or a repl (like Ruby for Android) would be fine.
2. What editor for making "plain text" files with any extension do you use?
3. In desperation I tried using echo to create a new shell script file the other day, and Android OS complained that the file system was read only. Can I make it r/w from within the android, or do I need to use ADB?
Thanks in advance. I tried googling for answers, but to no avail.

Well you could flash Debian to a JF build and go from there.

You can remount it as r/w from the device. I can't remember exactly what the command is but it is something along the lines of "mount -oremount,rw /dev/block/mtdblock0 /system" anyone care to correct me if that is wrong? You can also use DroidSans Tweak Tools available free in the market, just don't use the lite version

almosst correct on the command there, there is actually a space between the "-o" and "remount" so it should read
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
that would make your system partition read write, but if you wanna run shell scripts i would go grab gscript and just write them in there.
oops i typed it wrong i switched the rw and remount, it's fixed now sorry

Haha that's funny. Ive been typing: "mount -o rw, remount -t yaffs2 /dev/block/mtdblock3 /system"
But. That's just what works for me. Found it when I first rooted my phone.

Allowing non market apps to be installed on locked down phones (backflip)

Hey guys,
My uncle works for Motorola and gave me a prototype phone (which I believe will be called the Motorola Sage, and it's model number is MB508. This thread isn't really about that, I can't post pictures because I don't want to get anyone in trouble). This phone is an AT&T phone, complete with AT&T startup screen, uninstallable AT&T apps and of course the inability to install non-market apps. Also it's running Android 2.1.
Now, I seem to have default root access to this phone. I'm assuming the file system is very similar to that of the Backflip (which I was previously using until I received this one). From what I've read and learned from poking around in /system/etc, non-market apps are blocked by two config files. These are:
/system/etc/motorola/com.android.providers.settings/secure.mkitso
Code:
# cat secure.mkitso
cat secure.mkitso
location_providers_allowed=network,gps
wifi_on=0
data_roaming=1
bluetooth_on=0
install_non_market_apps=0
usb_mass_storage_enabled=1
and
/system/etc/motorola/com.motorola.android.providers.settings/settings.mkitso
Code:
# cat settings.mkitso
cat settings.mkitso
mms_maximum_message_size=614400
auto_scan_on_flip=true
sms_pref_key_emailgateway_num=121
Single_Digit_Dial_Enabled=True
roaming_icon=0
dun_enable=1
force_only_market_apps=1
Bluetooth_Dun_Enabled=true
mms_x_wap_profile_url=http://uaprof.motorola.com/phoneconfi/MotoMB51/profile/MotoMB511.rdf
sms_pref_key_to_email=1
Okay, now it would seem that it's a simple matter of changing the values for "force_only_market_apps" to 0, and "install_non_market_apps" to 1. I did this, and let me quickly tell you how I did it.
- Make /system writable: mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system
- Copy mkitso files to sdcard
- Edit mkitso files using Notepad++, changing the values as stated above
- Copy mkitso files back to their original directories
- chmod 644 to the files in order to keep their original permissions
- Make /system read only again: mount -o remount,ro -t yaffs2 /dev/block/mtdblock4 /system
- Restart the phone
However, this did not work, as I still get the warning when I try to install a non-market app.
I was wondering if anyone had any ideas on this, as when the Backflip gets rooted this is one thing that I'm sure we would like to know.

Have you tried adb install? I've heard that works on Backflops. You could download the app to your PC,and install it using "adb install PATH/TO/APP.APK"

Thanks, I know that I can use adb to install non market apps, but I was looking at how to change this setting on the phone. Since I have root on my phone, I figured it was possible.

Check out some of these terminal apps found in /system/bin/ directory of the backflip.Maybe they will help you.

EDIT:Also there does not seem to be a com.android.providers.settings in /system/etc/motorola/ only com.motorola.android.providers.settings and the file located in that directory is named secure.mkitso and the market app setting is set up like this:install_non_market_apps=0
So there is a slight difference in how the devices are set up and maybe a bit less security on the backflip =)

Thanks for your suggestion, but if you read above I changed the mkitso files without any changes in the behavior of the phone .

I was thinking that since I changed the settings files and they didn't do anything, maybe they will be applied during a hard reset. I'll try that sometime this weekend and report on the results.
The reason I'm asking for help is because I believe that once the Backflip gets rooted, we will need to know how to disable this setting.

I doubt you have root unless it came already rooted (you did make up some **** about a prototype) I honestly think this wont be a hard issue to tackle or work around when root is achieved on the Lackflip...yes I did Lackflip on purpose because of how crippled it is..so spend your time ANNONYMOUSLY sending www.endgadget.com some nice shiney pics of your supposed prototype codnamed:
"Motorola Sage"

I'm not sure why you're so aggressive, Honestly77. I'm able to "su" in shell and I'm able to modify files in the /system folder, so unless I'm mistaken (which I very well might be), then I believe I have root on the phone.
It is a prototype phone for testing, so it coming rooted isn't too farfetched at all.
When the Backflip does get rooted yes, this will be an easier issue to solve, but I'm trying now. If we're able to figure it out now then no time will have to be devoted to it when the Backflip is rooted.

Alright, I just did a hard reset and it activated a menu toggle under Settings -> Applications -> "Unknown Sources: Allow install of non-Market applications" which can be checked or unchecked.
To summarize, if you have root on your phone, edit secure.mkitso and settings.mkitso and change the variables, then you need to hard reset the phone.

hey met3ora, I too have a backflop, I am currently trying to sell my soul to obtain some sort of root or even simple control over the device, I have 2 questions for you...
1: using the config files and other software availible on this forum, would it be possible to obtain a workaround to be able to install apps from sd? I'm sure you are well aware that the backflip has no memory and won't even allow market apps to be installed via sd.
my second question (its ok if you don't want to answer as we will find out soon enough)
is: the moto sage, how does it compare to the backflip? no specifics needed just, is it better?
Iv'e seen the photos of the sage that appeared a couple weeks ago and it looks good, just incase we need it you should copy the system files as I'm sure the one AT&T will give us will be on lockdown as well. Thanks!

THis thread is old but it still helped me with a bravo. Thanks OP.
And to this guy above, wtf, why be such a douche? You are also clearly an idiot or you would know that engineering models always have root.
Calling the OP a liar was way out of line and you should apologize.

Android/Linux question for rooted Galaxy Tab

Hi there
My knowledge of Android is very limited, I know a little about Linux from Ubuntu at command promt level, but not enough to fix this issue I'm having. Any help would be much appreciated.
I wish to modify a file which Android is telling me is locked. It's \system\etc\bluetooth\audio.config
I have found a modification to this file which may help me in connecting the Tab to a bluetooth peripheral I have.
I have rooted the Tab
I have installed a root file manager
I have installed a terminal app
I have tried to chmod this file when logged in as su, but this refused so still I cannot edit the file.
I read somewhere about mounting the system folder as rw, but this is a bit beyond my knowledge. So if this is necessary I need walking through this step-by-step.
Could someone please help me by posting some instructions to get me to the point where I can edit the file audio.config?
Many thanks
Gary

su
mount -o remount,rw /dev/mtdblock3 /system
You may still not be able to modify a file so copy it to /mnt/sdcard/file and edit it there and rename the source file when ready to mv it back in.
mount -o remount,ro /dev/mtdblock3 /system
when done.
This worked for me on my new Galaxy Tab Wifi after using A4 to root it.

Debian on droid 2 / droid 2 global

First off, This is probably in the wrong space, simply because I haven't reached my proper post count. (Too much of a lurker, sorry) but I think I've found something that will make fellow D2 / D2G smile, and I couldn't help but share this.
Here is where I got the idea from:
http://forum.xda-developers.com/showthread.php?t=962974
Unfortunately, the debian-img.zip link is no longer functional (at least it was the last time I checked). No big deal, you can get it from here: Debian-img.zip.
Download that, and make sure you have your Android sdk tools installed. You will need root and busybox. Connect phone to computer, memory card mode, create folder called debian, and unpack the debian-img.zip file into the debian folder on the sdcard. When complete, switch it to charge only mode and now for the fun to begin.
Open the command prompt, navigate to sdk\tools folder, and type adb devices. If you don't see your phone listed as a device (will be a bunch of letters and numbers) switch it to pc mode, run adb devices again.
Once it shows up, type the following:
adb shell
su
mount -o remount,rw -t yaffs2 /dev/block/mmcblk1p21 /system
export bin=/system/bin
export img=/sdcard/debian/debian.img
export mnt=/data/local/debian
mkdir /data/local/debian
export PATH=$bin:/usr/bin:/usr/sbin:/bin:$PATH
export TERM=linux
export HOME=/root
busybox mount -t ext3 -o loop,noatime,nodiratime $img $mnt
busybox mount -t devpts devpts $mnt/dev/pts
busybox mount -t proc proc $mnt/proc
busybox mount -t sysfs sysfs $mnt/sys
busybox sysctl -w net.ipv4.ip_forward=1
echo "nameserver 8.8.8.8" > $mnt/etc/resolv.conf
echo "nameserver 8.8.4.4" >> $mnt/etc/resolv.conf
echo "127.0.0.1 localhost" > $mnt/etc/hosts
busybox mount --bind /sdcard $mnt/sdcard
busybox chroot $mnt /bin/bash
if ps -Al | grep vnc > /dev/null
then
echo "vnc detected"
else
export USER=root
rm -r /tmp
mkdir /tmp
vncserver -geometry 854x480
fi
exit
mount -o remount,ro -t yaffs2 /dev/block/mmcblk1p21 /system
You can't just copy/paste that whole block of code due to the busybox commands. Copy and paste one at a time. I also found that you can't make a script with that code either (please prove me wrong!) and have it work on the droid2 or d2g without errors.
Once you put in the last command, hit ctrl+c, and then open AndroidVNC, using the following data (similar to the debondroid thread):
nickname: debian
Password: password
Address: localhost
Port: 5901
Then connect!
Issues:
I have found that not only can't I use a script, I also cannot use a terminal emulator or even connectbot to put in the commands line by line. I am unsure why, but this only seems to work when I use the adb shell through a computer/usb connection.
You may have issues using USB SDCARD mode after you have run this code. This is fixed by rebooting the phone (as this causes debian to stop being run, and the img is being run off the sdcard, which is mounted with busybox into the system). Otherwise, all other phone functions work perfectly.
A neat little bonus: I found that I am able to access the internet through a browser in debian using nothing more than my 3g data connection.
Feel free to comment! Especially if someone out there can get these commands to work as a script. Enjoy!

im dieing to get this running, i have D2G running miui ics, first i cant download debian-img.zip, it wont complete download. after searching and downloading debian arm iso and renaming img i try your instructions and get hung up at
busybox mount -t ext3 -o loop,noatime,nodiratime $img $mnt
any help would be apperciated thank you

It's possible the latest ICS leak could be the problem (I had only tried this on an old Fission build, stock (both) and CM7). However, sometimes when I would reset the phone and run the commands again, it would throw me an error in the same spot you're having. It was wierd (as it JUST worked). I flashed to a different ROM to see what was up and it was happy again--but only through one power cycle. There might be a spot in this code I'm missing, but the error it throws acts as if I were trying to mount the img in the wrong loop block. This could be to the loop block already having the residual data (from the forced shutdown of the phone not allowing a tru closure of Debian), and if that's the case It would make sense if we could wipe that loop block (del and recreate it) through ADB. I haven't had time, but I'll look into it tonight.
As for the img, I'll also look into that tonight (on my phone currently).

I really apperciate the speedy reply, I'm not showing ext2 or ext3 on miui ics, do you know of a working GB rom that debian works with. I really apperciate your work in getting this going, I'm surprised its not developed by more people as the idea of having a desktop computer in your pocket is appealing. Thanks again

That's the beauty of this workaround: D2/D2G doesn't have ext3 support. That's why I had to use this method and frankly could be one of the reasons that there are those out of the blue errors that don't make sense. I need time so I can get screenshots up (to prove I'm not lying), but this will work with the img file linked.
For a good GB build, you can try the latest CM7 build at rootzwiki, or the stock GB update.

I tried again and almost everything went smoothly until i punched in "fi" and it gave me an "Unknown hz value! <80> Assume 100." i finished the instructions and tried to fire up androidvnc and tried to connect and i get " VNC connection failed! localhost" so im going to try and attach a bmp of my cmd window. i am looking into the unkown hz value but so far am stumped. "change ext of file to bmp or png"
also im assuming the debian img which i was able to successfully download is a arm distro?

omg it worked!!!! i redid the steps like i had done i was still getting vnc connection error, then i changed the address in vnc from "localhost" to "127.0.0.1" and it works!!! thanks man

Debian img is indeed for ARM. And I haven't seen that error at all before, so I don't know what to tell you. Was working on school projects all night and just ran out of time, so didn't get to fire it up for screenshots, but it looks like you got it to work.
The next thing I'm gonna try is to put it in script form, and I think the solution is to put the busybox parts into a seperate script (android seems to like parsing the scripts all at once, so this borks the busybox commands).

I noticed that its busybox killing the script as well, good luck on compiling one that is compatable i will do wht i can on my end though i dont expect it to be much, thank you for putting this up, one more notch android has over the big apple

[Q] Send files to a mounted windows share using adb

Kind of a one-off question... I'm working on a project that will automatically dd image an android phone to an off-phone location (the host computers d: drive for example) using a script executed through adb. It has to be automatic and the resulting dd image absolutely cannot be written to the phones memory.
Maybe something like:
Code:
$ su
# mount -o rw,remount -t vfat /dev/block/mmcblk0p4 /dd
# dd if=/dev/block/mmcblk0p1 of=/dd/system.dd
I've tried the cifs route but sadly, it appears the cifs.ko and slow-work.ko modules haven't been done for my handset (or I may be so stupid I can't even follow directions. It's a real possibility).
I thought I'd use the time-tested netcat method but again, I can't locate the nc binary for netcat that will run on my handset.
Any alternatives? Anyone know where the G2X specific kernel modules can be had? Someone maybe have an android nc binary?
