Android: Requesting root access in your app
转帖：http://www.stealthcopter.com/blog/2010/01/android-requesting-root-access-in-your-app/
This snippet shows how root access can be requested inside an application in order to write a file into a place we do not have permission to access usually. Requesting root access will only work if your phone allows it, or it has been ‘rooted’ (hacked to allow superuser permissions).

Process p;
try {
// Preform su to get root privledges
p = Runtime.getRuntime().exec("su");
// Attempt to write a file to a root-only
DataOutputStream os = new DataOutputStream(p.getOutputStream());
os.writeBytes("echo \"Do I have root?\" >/system/sd/temporary.txt\n");
// Close the terminal
os.writeBytes("exit\n");
os.flush();
try {
p.waitFor();
if (p.exitValue() != 255) {
// TODO Code to run on success
toastMessage("root");
}
