I have my Ubuntu Server 16.04 LTS running and at the end of the day I want to shutdown my server from android device.
I have created a php file (API.php) as below.
<?php
shell_exec("shutdown -P now");
?>
And in android app there is a button, and OnClickListener is as below:
String serverURL = "http://hostIP/API.php";
new LongOperation().execute(serverURL);
the LongOperation class is as below:
private class LongOperation extends AsyncTask<String, Void, Void>{
private final HttpClient client = new DefaultHttpClient();
private String content;
private String error = null;
private ProgressDialog progressDialog = new ProgressDialog(MainActivity.this);
@Override
protected void onPreExecute() {
progressDialog.setMessage("Shutting down...");
progressDialog.show();
}
@Override
protected Void doInBackground(String... params) {
try {
HttpGet httpGet = new HttpGet(params[0]);
ResponseHandler<String> responseHandler = new BasicResponseHandler();
content = client.execute(httpGet, responseHandler);
} catch (IOException e){
error = e.getMessage();
cancel(true);
}
return null;
}
@Override
protected void onPostExecute(Void unused) {
progressDialog.dismiss();
Toast.makeText(MainActivity.this, "finished", Toast.LENGTH_SHORT).show();
}
}
this code runs successfully on my localhost but when I put the ip of my server and rerun it, nothing happens.
How to shut down my ubuntu server successfully?
