[android-developers] Re: Copying a file from assets or raw to /system/bin folder (rsync)
Chris, I am only trying to justify my questioning on this forum. The steps mentioned on the rsync wiki work on a emulator. I assumed it would work on the device since it does on the emualtor. I was wondering what I was doing wrong, so wrote a piece of shareable code that can put up on a public forum. Obviously you will realize that I cannot put up production quality code up here. By the way, I am not getting personal. I will and have not written anything derogatory. All I said was I assumed that the rsync guys would have tried it out on a real device, but may be its just in beta stage now. Again, I am only trying to justify my questioning on this forum. I used android sdk to develop a app to auto deploy a tool that I believe is helpful. It works on a emulator, does not on a device. Thats it.. Yes, I did put up a question and a marked a bug on the rsync project too. I politely request that you refrain from be derogatory on a public forum. This is my last mail on this topic.

Re: [android-developers] Re: Copying a file from assets or raw to /system/bin folder (rsync)
Data files don't go on /system, so what you are trying to do doesn't make sense. Nor is it possible for normal applications to do. A good Android device will not allow /system to be mounted read/write under normal operation.

[android-developers] Re: Copying a file from assets or raw to /system/bin folder (rsync)
Just wanted you to know that rysnc droid is a project for android. If the install steps dont work on a android device, android forum is the best place to seek advice. Dont get me wrong, but getting a android app to work, I was assuming that the developers of that app would have done enough research to get it to work on a real device. I guess not enough. When I put up the question I was thinking may be I was doing something wrong. Then it struck me, why system/bin.. It can be just any other folder.
