Unable to input "enter" key event from within my app android

Question

I want to input "enter" key event programmatically from within my app.

I have tried it using abd shell command as well as using AccessibilityService, but found no luck in it.

Below is my code which I used to execute adb shell command :

try {
    Runtime runtime = Runtime.getRuntime();

    Process p = runtime.exec("input keyevent 66");

    BufferedReader standardIn = new BufferedReader(new InputStreamReader(p.getInputStream()));
    BufferedReader errorIn = new BufferedReader(new InputStreamReader(p.getErrorStream()));

    String output = "";
    String line;
    while ((line = standardIn.readLine()) != null) {
        output += line + "\n";
    }
    while ((line = errorIn.readLine()) != null) {
        output += line + "\n";
    }

    Log.d("output", "" + output);
} catch (IOException e) {
    e.printStackTrace();
}

I am getting the following output :

sh: resetreason: can't execute: Permission denied

Someone please help me out.

If anyone knows how to achieve it using AccessibilityService as well, please let me know.

Thanks in advance!

Added the above permission, but still throwing same output error. – Wazz Apr 08 '16 at 07:32
I think the above permission and the above code will only work on rooted devices. – Wazz Apr 08 '16 at 12:27
