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...
I am newbie in Windows Phone 7 development.
I am trying to unzip a file that was downloaded to isolatedstorage in WP7.
I have tried with ShapZipLib but with no success. Does anyone have an example on how to do this in WP7?
Thanks a lot !
seems like there is no way to unzip a file in isolated storage ,but you can browse a zip file via IE........ if that zip file is on the internet

Use DotNetZip library, it has a SL implementation (works fine on WP7 but requires some minor tweaking).
By the way, if you have problems with SharpZipLib (also works fine on WP7 but also requires some tweaking/reassembling), I'll recommend you to learn more about WP7/Silverlight programming first. Sorry I have no time to teach you how to write programs on WP7...
WP7 actually has a Silverlight API to extract specific files from a ZIP archive directly. This is technically an undocumented use of this API, but it does work:
Uri filename, zipname;
filename = new Uri("<FILE_TO_UNZIP_FROM_ARCHIVE>", UriKind.Relative);
zipname = new Uri(@"\Applications\Data\<APP_GUID_HERE>\Data\IsolatedStore\<ZIP_ARCHIVE_NAME.ZIP>", UriKind.Relative);
Stream filestream = Application.GetResourceStream(Application.GetResourceStream(zipname), filename).Stream;
Then, you can use standard Stream functions to read the file from within the ZIP, including write it to an IsolatedStore file.
The only undocumented part of this is that you actually can pass fully-qualified paths to the Uri constructor and then open them using GetResourceStream... just so long as the Uri is constructed as Relative (even though it's not) and the file is one that the app has permissions to read (which typically means its Install directory, its data directory, and the Windows directory). The use of nested Application.GetResourceStream to read inside a ZIP file is actually documented.
I'm trying to covert a thin-client RDP system into a standalone linux system. I'd like to run a lighthttp server on it and auto-boot it to chromium (on start up).
The device comes with a crappy RDP interface and has a method for installing software UPGRADES via FTP. --- Confirmed working.
Doing some research on the web I was able to find an update package for this device. ATTACHED AS TORRENT FILE.
Using CENTOS I've tried to extract the RAMDISK but Linux doesn't seem to know how to extract the file type. I've tried a ton of scripts from xda-devs none seem to work.
I've tried just changing the system dir to see if I can get that work but it seems that the new image doesn't take to the device. I did see that the scripts have checksum info in them but not sure how to repackage or change them to adjust for the new changes.
I do see the build.prop file with a ton of ANDROID stuff and the package is APK signed. Thus I'm thinking it's an ANDROID setup. Also I see that the device is using busybox.
Any help or ideas how to get this doing what I need it?
Thanks!

Any ideas out there?
Bump?
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.

did you find a solution to this? please reply if yes, I am having the same problem
Ok, so I have a PDF file that I have changed to Read-only in the file properties window on Windows 10. Then I take that PDF and copy it to a flash drive and put it on an Android device. When I load the file up in Adobe Acrobat for android and all of the sudden the file is not read-only anymore. I take the file and move it back over to Windows and the Read-only box under file attributes is unchecked. What gives? why is android willy nilly changing file attributes when they are copied onto the device. Using Email instead of a flash drive still produces the same results. I just want a PDF file that just stays read-only when I mark it as such. I'm going to give this file to people that I know will probably load it up on their phones to use it from there, but I want the read-only attribute to persist, even when being moved from system to system, be it Windows, Android, or Apple.

You probably also need to change administrator/ownership/ permissions on the file.
The link below discusses the issue.
Windows 10 - Read-only File Flag Has No Effect
I want to disable files from being overwritten in Windows 10. I figured that was the use of the 'Read-only' file flag. But after enabling it, it appears programs (at least the program it opens in) ...
