Changing file permission attributes - G1 Android Development

Hi everyone,
I'm trying to run from an app a script that it's located in the Data/data/.... directory and i'm having problems setting the exec. attribute for that file. Is there any trick in the implementation of the permission method??? or is there anything special at the moment of creating such file.
Thanks

You're going to have to be a bit more specific. I have no idea where to start.

Examine the method prepareSu() from Superuser's UI:
http://code.google.com/p/superuser/...koushikdutta/superuser/SuperuserActivity.java

I have a script that i need to run from an application but the file doesn't have the executable attribute, and the java method to change those atributtes doesn't work, i hope that makes a little more clear my problem...

Executing file from flash-card immediately after booting..?

Hey people on the board!
I'm a relative newbie in this PDA-stuff so I have a question which perhaps (hopefully) is easy to answer. Problem:
I have an application which I run on my Qtek 1010. The application runs fine, but prior to using it, a significant amount of time must be spent on installing and configuring it. In case of battery-faliure, this needs to be done from scratch. I would therefore like the Qtek to execute a script-like file (autorun.exe) which performs this task, immediately after booting.. The file is present on a flash-card inserted in the slot. How do I do this? Where - on the card - do I place the file? In the root? And how do I detect it and run it automatically after a cold-boot?
Any help would be greatly appreciated! Thx!

Its quite simple
Hi there, your problem to fix is quite easy.
If you look in in your windows directory with the built-in explorer, you'll find a directory - either "startUp" or "Autostart" depends on the system language you are using. Here you put a link to the program you're having on card. With every cold- or warm boot it will be executed. :lol:

On the memory card make a directory named 2577, I believe the pocket pc will look here for your autostart on boot, try it and see. You can try putting a cab file in there or your autostart config file. I am not an expert in this but thats how its done with ipaq navigation system which is an automatic routine using the 2577 directory and I have also seen other software using the same method.
the file should be called 'autorun.exe' in the '\storage card\2577\' directory.
when you insert the card, the autorun.exe will be copied to \windows, and executed with 'install' as parameter.
when you remove the card, it will get executed with 'uninstall' as parameter.
and then removed from \windows.
but this will not nescesarily happen at boot.
just figured out another thing: the number you put in the .lnk file in \windows\startup is completely ignored by windows.
also, if the executable is in \windows, you may omit the path,
you may also omit the extension if it is .exe.
if you specify commandline parameters, your application will get passed upto 255 characters starting from the first non-whitespace character after the executable name.and including any newlines that may be in the file.
Hi!
Thanks for the response. I'll give the methods a try during the day and get back.
Thanks so far - I appreciate it

Hi there (again)!
I have tried the different suggestions with no luck. Perhaps I should have been a bit more specific. What I actually need is to have the autorun.exe run (install) a number of cab-files also on the flash-card. I was - perhaps naively - thinking that there would be a generic tool out there to create this type of autorun.exe file? I am looking for something along the lines of what is being done here:
http://forum.xda-developers.com/viewtopic.php?t=508&highlight=autorun
Only, in the case above, the autorun.exe lauches a specific .cab-file which contains a ROM for the PDA.
Is there a "configurable" .cab-installing autorun.exe out there somewhere? Or should it be written from scratch every time for new purposes?
Hope I make myself clear

yes, it is in the extended rom, processing the config.txt file.
eeeh, but the location of the config.txt is taken from the registry, which is currently always set to \extended_rom\config.txt.

Could you explain that to me in more detail, please? As I mentioned, I am a relative newcomer in this Xda stuff Thanks..
/Joe72
what you are asking for is the autorun.exe found in the extended rom,
look for 'extended rom batch language' on the forum for details.
problem is that the autorun.exe from the extended rom uses the config.txt
pointed to by the "[HKEY_LOCAL_MACHINE\Comm] AutoRunCfg" registry value. which always is '\Extended_ROM\Config.txt"
what you could do, is change the 'autoruncfg' string in the autorun.exe binary in to something else. and then fill your own config.txt path in that registry value.
Thanks - that sounds like the way to do it. I guess I would copy the original config.txt, add my .cab-files, put it on the flash-card and then change the key in the registry to point to the card. Is that how it would go?
Now another stupid question: How do I access the registry? There is apparently no regedit.exe like on my desktop?

Managed to access the registry using Windows CE Remote Registry Editor. But whooops.. After a cold boot, the registry is reset to factory settings?! Hence my changes of the path to config.txt are also lost..? What to do?

Help me out! editing XML file..

I just recently checked out LauncherPro beta, and i really like it, my only problem is that the shortcut icons arent really what I like.
All I want to do it edit the default_workspace.xml so that the target APKs for the shortcuts will be Phone, Messages, Gallery, and Browser. I've already edited the icons to reflect that.
I already decoded the binary XML, I just need to know how to re-compile it to a binary XML after editing.
Sorry guys, I'm a complete noob when it comes to any kind of coding... and thanks in advance
edit: I already read Stericson's sticky, but I either just didnt get it, or didnt see anywhere to re-compile a decompiled binary XML.
If you have used AXMLPrinter to decode XML, then no, you can't compile it back. It's for looking into XML files only, not for editing them as text.
AFAIK my apktool is only one tool, which gives you possibility to edit XML files easily:
http://forum.xda-developers.com/showthread.php?t=640592
AXML is what I used, but re-editing it is no problem. I tried using apktool, but it gives me a "java" is not recognized as an internal blah blah message.. I've googled it, and made sure the environment variables were correct also, just updated Java a couple hours ago as well.
edit: and oh, thanks for the reply.. it's the only one I've gotten so far between here and droidforums so far.
I don't really know, why you don't have java command set in your PATH - I think Java installer does it automatically :-/ You could find java.exe file on your disk and:
Add it to PATH - there are many arts about this in the internet.
Edit apktool.bat file to call java command using full path, i.e. replace "java" with something like: ' "C:\Program Files\Java\java.exe" '.
Don't use apktool.bat, call Java directly: ' "C:\Program Files\Java\java.exe" -jar %WINDIR%\apktool.jar d somefile.apk outdir '

[Q] How can I change file path inside of a exe file?

Hi.
First of all, let me say that half of time took me to look for the right forum in XDA to post this message, and I'm still not sure I'm in the right place..
I think my Q is about modifying my OS, and this is why I post it here.
If the admin think there's better forum to this issue - I'd love to hear it..
Now, to business:
I have a GPS device, brand is X-GPS Navigation, Model GPS-S450B, that I will like to play with.
The OS is Windows® Embedded CE 6.0.
I just found out that at my GPS device, there is a file that resposible to a certain BMP that shown up at the shutdown process.
The filename is "PowerKey.exe", and it reffer to a file named "Notice_en.bmp".
I want to change that Notice-en.bmp file, to show that message in another langueage. I tried to overwrite the file with a similar bmp file, no luck. The file just re-created.
I've tried to edit the PowerKey.exe with a hex editor, and write a new path, to a file in NandFlash directory instead of the Notice_en that lays in Windows folder.
That also didn't go so well. "PowerKey has been preform illegal action and have to be shout down" or something like that, was the message. I could only put the device to sleep, until I recovered the old PowerKey file.
Any solution how to change the BMP file that resposible for the shutdown message?
(I guess the best idea is to write a registry entry to overwrite the BMP file in \Windows directory with the one in the \NandFlash directory every boot, only problem - I donno how to do it. )
Anyone?
There's no solution to my problem?
Recompile the exe.
Thank you.
Any chance to general guidlines in how is that done?

Add APK - repack system.img

I was looking for a similar topic but I did not find one. Refers to problems with running applications added to "system.img".
I bought UMIDIG S for my father-in-law. It is based on a mediatec chipset. Unfortunately, soft is tragic, and there is no full translation, so I decided to bury it a bit in "system.img".
I can easily install the file in Linux and make changes in it. I can delete applications, I can make changes in configuration files and "buikd.prop".
Unfortunately, all APK files were uploaded to "system.img" even though I set permissions 755 for directories, and 644 for directories. Although the files are root: root, after uploading such "system.img" none of these applications works for the phone. The system sees them and tries to load. Unfortunately, applications hang because of errors. The system informs that the application hangs, and does not load its window. The icons of these applications and the names do not appear either (applications have green robocik as icon, and domain name, e.g. com.android.clock ....)
I am asking for advice. How to add APK files to the unzipped "system.img" so that after packing and uploading to the phone there were no errors ???
Do you have found how add app in system.img?
It's all around, but you can replace apps with others. In the linux system, unpack the img, and mount them. Then you can freely rename files as well as move files within the .img mount point
I chose the applications or other files I did not need, and moved them to the directories (which I named my applications). If the application needed libraries, you also had to get files in a similar way, and place them in arm or arm64 directories.
Then prepared files "stuffed" with data, using the command DD. That is, dd if = (source file) of = (the recipient file at the system.img mount point).
Thanks for reply, so this only on Linux? For Windows there is something?

I do not know, I do not use Windows. Certainly you can in a similar way from BSD systems, probably from Android and MacOS. I read something that Microsoft can somehow support linux shell, but I do not know the details. You can always use some distribution that works with a pendrive.
Thanks, I will try again

You can use Virtual Box to run a Linux distro inside Windows or you can try using Cygwin.

How to overwrite system file with script

This script creates another file in the same directory, with the *same* name as the desired target file:
There are now two files in the same directory with the same name (???). The original file has an Android icon, and the new file has a text icon (Total Commander).
#!/bin/bash/sh
...
echo $RANDMAC > /config/wifi/mac.txt
I'm trying to create a script, and maybe eventually an app, to randomize the MAC address and host name.
Changing the MAC on my rooted Nextbook Ares 8 requires editing the mac.txt file. (The normal methods fail.)
Android 5.1.

may be you can post your whole script so that someone knowledgeable can help you

Hi. The only part left out is what sets $RANDMAC, and it isn't relevant. If you echo to the screen, the format of the MAC address is the same as in the original mac.txt file.
I'm looking for an active Android tablet forum, if anybody knows of one.
I also posted this question at android.stackexchange.com. The post has gotten 16 views in two days - and most of those are mine, from visiting the page when I'm not logged in.
