Use it, as it will be more portable across devices, allow you to more easily detect failures, will not require a busybox install, and will be more likely to continue working on future Android versions. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Even more than more likely I would think it would be insane if *that* interface quit working :-P kris -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: How to use cp (Copy) command in system function in native C code on Android
Thanks for Your Reply See my question properly. i want to to do copy via native code , i already installed busy-box so i can able to use cp command on android shell. cp command is working directly on shell but its not working via system call. So i want to know about how can i achieve this goal via system call.

So we can say system function is working in Android. I also installed BusyBox so I can use the cp command also. If I execute directly cp /mnt/test /Download/ command then it's working fine. So what is problem here in system function. Have I missed something? Thanks Sam Jona -- You received this message because you are subscribed to the Google Groups Android Developers group.

What you are doing is not supported in the SDK, so this is not an appropriate place to ask about it, sorry.

Re: [android-developers] Re: How to use cp (Copy) command in system function in native C code on Android
Hi kris and dianne If sdk is not supported than why this cp command is working if i execute on android shell manually. And i know android sdk is not supported cp command and so i installed busybox in this so i able to use cp command manually on amdroid shell. Now i am using system function which define in stdlib.h file of C. If i am able to do all operations of c code like fopen fclose and other functions of c via native code. Here i implemented native c code to execute c code in android. So dats why i am telling may be its possible Thanks On Mar 22, 2012 8:07 AM, Kristopher Micinski krismicin...@gmail.com wrote: Heh, It appears I spelled Dianne wrong... sorry about that... kris On Wed, Mar 21, 2012 at 10:25 PM, Kristopher Micinski krismicin...@gmail.com wrote: On Wed, Mar 21, 2012 at 10:07 PM, A B saurbh...@gmail.com wrote: Thanks for Your Reply See my question properly. i want to to do copy via native code , i already installed busy-box so i can able to use cp command on android shell. cp command is working directly on shell but its not working via system call.
