Copy folders in /data/data to sdcard & vice-versa

android, android-sdcard, copy, directory, root

Solution

At the end I got it!!!!

I use the SuperUser process with the cp command to copy the files and folders.

I hope you find it helpful.

String comando = "cp -r /data/data/sourcefolder /sdcard/targetfolder";
Process suProcess = Runtime.getRuntime().exec("su");
DataOutputStream os = new DataOutputStream(suProcess.getOutputStream());
os.writeBytes(comando + "\n");
os.flush();
os.writeBytes("exit\n");
os.flush();
try
{
 int suProcessRetval = suProcess.waitFor();
 if (255 != suProcessRetval)
 {
  // Acceso Root concedido
  retval = true;
 }else
 {
  // Acceso Root denegado
  retval = false;
 }
}
catch (Exception ex)
{
 Log.w("Error ejecutando el comando Root", ex);
}

Thank you very much to all the people of this forum and for all the help which you offer!!

Problem

I have a problem when I try to copy folders inside /data/data to SDcard. I have my phone rooted. I request Superuser permissions in my app with: ``` Runtime.getRuntime().exec("su"); ``` I'm using `FileUtils` from Apache to copy files/folders. What I discovered is if I manually change the folders permissions to `READ` I can copy it from /data/data to SDcard. Is there any way to recursively change the `RW` permissions of all folders inside /data/data to read and write folders? I've tried `chmod` but It doesn't work. ``` Runtime.getRuntime().exec("chmod 777 /data/data"); ``` I want to do a backup program and i want to read some folders inside /data/data and write them in a SDcard's folder. Then I want to restore this folders reading them from a SDcard's folder and write them in /data/data. Could you help me, please?
