running adb root

[OctavianIonel]

Hi @cgutman,
I would like to run a command "adb root" and not passing through adb shell (which works):
using adb shell: getprop ro.build.version.incremental it is working:

                            String getpropCommand = "getprop ro.build.version.incremental";
                            AdbStream streamGetpropCommand = connection.open("shell:" + getpropCommand);

                            while (!streamGetpropCommand .isClosed()) {
                                try {
                                    String result = new String(streamGetpropCommand.read(), StandardCharsets.US_ASCII);
                                    // Print each thing we read from the shell stream
                                    System.out.println("-->step1: getprop result: " + result);
                                    if (!result.isEmpty()) {
                                        streamGetpropCommand.close();
                                    }

                                } catch (InterruptedException | IOException e) {
                                    e.printStackTrace();
                                    return;
                                }
                            }

and when using adb root does not work:

                                    String rootCommand = "adb root";
                                    AdbStream streamRootCommand = connection.open(rootCommand);
                                    while (!streamRootCommand.isClosed()) {
                                        try {
                                            String result = new String(streamRootCommand.read(), StandardCharsets.US_ASCII);
                                            // Print each thing we read from the shell stream
                                            System.out.println("--> step2: adb root result: " + result);
                                            if (!result.isEmpty()) {
                                                streamRootCommand.close();
                                            }

                                        } catch (InterruptedException | IOException e) {
                                            e.printStackTrace();
                                            return;
                                        }
                                    }
