How to open Device administration through Appium?

1

I tried adb command through java code, but it didn’t work.

Tried this in ADB command - adb shell am start -S com.android.settings/.Settings\$DeviceAdminSettingsActivity, it works well while performing it through command prompt, but fails when we run through java code.

public void openAdminSettings() { // for MAC. for Windows update accordingly
        try {
            String[] cmd = new String[]{"sh", "-c", "start_adb_shell_command_here"};
            ProcessBuilder pb = new ProcessBuilder(cmd);
            Process process = pb.start();
            final Scanner in = new Scanner(process.getInputStream());
            Thread t = new Thread() {
                public void run() {
                    while (in.hasNextLine())
                        System.out.println(in.nextLine());
                }
            };
            t.start();
            PrintWriter writer = new PrintWriter(process.getOutputStream());
            sleep(3); // just wait little bit for sure
            writer.write("here_is_shell_command \n");
            writer.write("here_is_shell_command_if_needed \n");
            writer.write("quit \n");
            writer.flush();
            sleep(1); // for sure little
            process.destroy();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
