Send data to a Php Script with Android Studio [duplicate]

This question already has answers here:
How can I fix 'android.os.NetworkOnMainThreadException'?
(66 answers)
Closed 3 years ago.
I have to send some parameters from my Android application to a Php script, for a database insert.
I tried this script on Eclipse and it works fine.
But when I try to run it on Android it crashes.
public static void Insert(){
try {
// open a connection to the site
URL url = new URL("http://192.168.1.105/JavaInsert.php");
URLConnection con = url.openConnection();
// activate the output
con.setDoOutput(true);
PrintStream ps = new PrintStream(con.getOutputStream());
// send your parameters to your site
ps.print("&email=random#gmail.com");
//ps.print("&Company=Company");
//ps.print("&Shares=Shares");
//ps.print("&Date=Date");
con.getInputStream();
ps.close();
} catch (MalformedURLException e1) {
e1.printStackTrace();
System.out.print("Db error 1");
} catch (IOException e2) {
e2.printStackTrace();
System.out.print("Db error 1");
}
}
There are these errors in the LogCat section

The Php script works with Eclipse.
I've also already added the android Network and Internet Permissions

its because you cant run network operation on main thread it will cause the NetworkOnMainThreadException which you have
try networking libraries or do the operation on a AsyncTask

You need to create a Runnable Thread or AsyncTask to run network operations.
Check out my example below
private void login() {
JSONObject request = new JSONObject();
try {
//Populate the request parameters
request.put(KEY_USERNAME, username);
request.put(KEY_PASSWORD, password);
//Log.v("test", request.toString());
} catch (JSONException e) {
e.printStackTrace();
}
JsonObjectRequest jsArrayRequest = new JsonObjectRequest
(Request.Method.POST, login_url, request, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
pDialog.dismiss();
try {
//Check if user got logged in successfully
if (response.getInt(KEY_STATUS) == 0) {
session.loginUser(username, response.getString(KEY_FULL_NAME));
loadDashboard();
} else {
Toast.makeText(getApplicationContext(),
response.getString(KEY_MESSAGE), Toast.LENGTH_SHORT).show();
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
pDialog.dismiss();
//Display error message whenever an error occurs
Toast.makeText(getApplicationContext(),
error.getMessage(), Toast.LENGTH_SHORT).show();
}
});

java.lang.RuntimeException: Unable to resume activity with java.lang.IllegalArgumentException

at android.app.ActivityThread.performResumeActivity(ActivityThread.java:3377)
Both in MainActivity and super class XActivity, only super.onResume(); is called. It's really strange to get this exception after a long time normal development.I checked some relative reference material but nothing got.

In the method Activity#isTopOfTask we can see:
private boolean isTopOfTask() {
if (mToken == null || mWindow == null) {
return false;
}
try {
return ActivityManager.getService().isTopOfTask(getActivityToken());
} catch (RemoteException e) {
return false;
}
}
And in ActivityManagerService#isTopOfTask we can found:
#Override
public boolean isTopOfTask(IBinder token) {
synchronized (this) {
ActivityRecord r = ActivityRecord.isInStackLocked(token);
if (r == null) {
throw new IllegalArgumentException();
}
return r.task.getTopActivity() == r;
}
}
So, I think that ActivityRecord is null.But I don't know why it is null....

There is insufficient information in your question to determine the cause of the java.lang.IllegalArgumentException, Unfortunately the android ActivityThread doesn't log the stacktrace of that exception, and the exception message appears to be empty.
However, it looks like there is a way forward. The exception is handled by the following code in the ActivityThread::performResumeActivity method:
} catch (Exception e) {
if (!mInstrumentation.onException(r.activity, e)) {
throw new RuntimeException(
"Unable to resume activity "
+ r.intent.getComponent().toShortString()
+ ": " + e.toString(), e);
}
}
If you register an Instrumentation class for your activity, it should be possible to use an onException method to log the stacktrace for the causal exception. Another possibility is to use Thread.setUncaughtExceptionHandler to set a handler for the thread in which the IllegalArgumentException is thrown.
These won't solve the problem (!) but it will get you a step closer to a solution.

The above class has been included in my MainActivity.java file.
http://rominirani.com/2014/08/26/gradle-tutorial-part-9-cloud-endpoints-persistence-android-studio/
I have been following this tutorial. I manually inserted quotes (Quote is the bean I am using) in the API Explorer and I successfully get the list of quotes in my emulator when I run the local server and test. However, when I deploy the same backend and run the application, I get a NullPointerException in the onPostExecuteMethod. Please help. Thanks!

Android FTP connection problems [duplicate]

This question already has answers here:
How can I fix 'android.os.NetworkOnMainThreadException'?
(66 answers)
Closed 7 years ago.
Hi I have been trying for two days to get a simple ftp connection to transfer a small xml file. I have tried lots of different examples of code, but all seem to give the same errors.
Main FTP class code:
public class MyFTPClientFunctions {
public FTPClient mFTPClient = null;
public boolean ftpConnect(String host, String username, String password, int port) {
try {
mFTPClient = new FTPClient();
// connecting to the host
mFTPClient.connect(host, port);
// now check the reply code, if positive mean connection success
if (FTPReply.isPositiveCompletion(mFTPClient.getReplyCode())) {
// login using username & password
boolean status = mFTPClient.login(username, password);
mFTPClient.setFileType(FTP.BINARY_FILE_TYPE);
mFTPClient.enterLocalPassiveMode();
return status;
}
//Log.d(TAG, "Error: could not connect to host " + host);
} catch (SocketException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return false;
}
private Context getApplicationContext() {
return null;
}
}
Main Activity code to send
send.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//set up FTP file transfer here
MyFTPClientFunctions ftpSend = new MyFTPClientFunctions();
ftpSend.ftpConnect("xxxxxx.asuscomm.com","admin","xxxxxxxxxx",21);
}

This Exception is usualy thrown, if you are using the network on the main thread.
Please use Async Tasks.

Android HttpClient Asynctask

I have been stuck on this problem for a day or two now, so i decided to see if anyone out there could help me.
The current goal i have, is to make a HttpPost that connects to, and executes a script that i have on my Wamp server. I have implemented a class that extends AsyncTask, and includes the 3 necessary methods, that are required in order for it to work effectively.
I will first show you the code that i have used to put the variables into a Json Object, followed by the JSONParser class, that initializes the HttpPost and then executes it.
Afterwards i will tell you all about the log errors and the narrowing down of the problem; you all problem know what the problem may be already, and if you don't want to read below, briefly, it is caused by the line of code that calls the parser class.
Note: I am using this as a starting point for this type of work, so please understand that it is simple in terms of its passed parameters.
Further Note: I am using Eclipse, and i am testing with the inbuilt Emulator.
METHOD - CreateNewUser
/**
* Background Async Task to Create new user
*/
class CreateNewUser extends AsyncTask<String, String, String>{
/**
* Before starting background thread show progress dialog
*/
#Override
protected void onPreExecute(){
super.onPreExecute();
pDialog = new ProgressDialog(AddUserActivity.this);
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
/*
* Creating user
*/
#Override
protected String doInBackground(String... args){
String username = inputUsername.getText().toString();
String password = inputPassword.getText().toString();
// Building parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("username", username));
params.add(new BasicNameValuePair("password", password));
// getting JSON object
// Note that create user url accepts POST method
JSONObject json = jsonParser.makeHttpRequest(url_create_user, "POST",params);
// check log cat for response
Log.d("Create Response", json.toString());
// check for success tag
try {
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
// successfully created product
Intent i = new Intent(getApplicationContext(), MainActivity.class);
startActivity(i);
// closing this screen
finish();
} else {
// failed to create product
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
/**
* After completing background task Dismiss the progress dialog
* **/
#Override
protected void onPostExecute(String file_url) {
// dismiss the dialog once done
pDialog.dismiss();
}
}
Next, the JSONParser Class:
public class JSONParser {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
// constructor
public JSONParser() {
}
// function get JSON from URL
// by making HTTP POST or GET method
public JSONObject makeHttpRequest(String url, String method,
List<NameValuePair> params) {
// Making HTTP request
try {
// check for request method
if(method == "POST"){
// request method is POST
// defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(new UrlEncodedFormEntity(params));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
}else if(method == "GET"){
// request method is GET
DefaultHttpClient httpClient = new DefaultHttpClient();
String paramString = URLEncodedUtils.format(params, "utf-8");
url += "?" + paramString;
HttpGet httpGet = new HttpGet(url);
HttpResponse httpResponse = httpClient.execute(httpGet);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
}
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
json = sb.toString();
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
// try parse the string to a JSON object
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}
// return JSON String
return jObj;
}
}
If i remove the line : ( JSONObject json = jsonParser.makeHttpRequest(url_create_user, "POST",params); ) - of course with intending the try catch out, then the program does not crash, when i press the button that calls the CreateNewUser class.
If i do not do that, my program brings up a loading screen that swirls around until it becomes unresponsive, and asks me to close down the application.

The script files themselves work as far as i am aware - besides, the program never executes the script from what i can tell.
If anyone could help me out, i would really appreciate it! I understand you are all busy people, so thank you so much for taking some time out of your day if you do post ideas :)

The clue is in the exception thrown:
Caused by: java.lang.IllegalStateException: Target host must not be
null, or set in parameters. scheme=null, host=null,
path=localhost/android_connect/sqlconfig/create_user.php
