I'm having a bit of trouble with a simple app I'm making.
I'll include the code:
import android.app.ProgressDialog;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.protocol.BasicHttpContext;
import org.apache.http.protocol.HttpContext;
import java.net.URL;
public class login extends AppCompatActivity {
EditText user;
EditText pass;
boolean result_back;
private ProgressDialog pDialog;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
Button log = (Button) findViewById(R.id.btLogIn2);
log.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
login(v);
}
});
}
public void login(View v)
{
HttpClient client = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpResponse response = null;
user = (EditText) findViewById(R.id.eTUser);
String usuario = user.toString();
pass = (EditText) findViewById(R.id.eTPass);
String passw = pass.toString();
String parametros = "?usuario=" + usuario + "&password=" + passw;
HttpGet httpGet = new HttpGet("http://gie.byethost.com/acces.php" + parametros);
Toast toast2 = Toast.makeText(getApplicationContext(), "Enviando datos", Toast.LENGTH_SHORT);
toast2.show();
try
{
response = client.execute(httpGet, localContext);
toast2 = Toast.makeText(getApplicationContext(), response.toString(), Toast.LENGTH_SHORT);
toast2.show();
}
catch (Exception e)
{
}
// response.toString();
if (response.toString().equalsIgnoreCase("1"))
{
Toast toast1 = Toast.makeText(getApplicationContext(), "Login correcto", Toast.LENGTH_SHORT);
toast1.show();
} else
if (response.toString().equalsIgnoreCase("0"))
{
Toast toast1 = Toast.makeText(getApplicationContext(), "Error de login", Toast.LENGTH_SHORT);
toast1.show();
}
}
}
There's only one button here and neither toast is showing, so I don't see where the app is crashing. Also, I'm a bit new in Android programming, so this may have an obvious solution.
Any comments will be appreciated!
You're doing a network transaction on the main thread. Never do that (or any blocking behavior) on the main thread. Your app might be crashing with an error in logcat related to "StrictMode".
Instead, you need to put all your blocking work on another thread. Android has very specific patterns about how to do that. It's not like you would expect in a normal java app.
You might want to consider doing a search for "android asynchronous programming" and learn about things like AsyncTask, Loader, and Service. There are a lot of great tutorials out there on how to use them. Please don't use Thread directly, as that will only cause you pain.

It's not even displaying the toast message after clicking the button. However it's showing error in android.os.NetworkOnMainThreadException.
Try this..
This exception is thrown when an application attempts to perform a networking operation on its main thread
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Context context = getApplicationContext();
CharSequence text = "Hello toast!";
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, text, duration);
toast.show();
messsage = textField1.getText().toString(); //get the text message on the text field
textField1.setText(""); //Reset the text field to blank
new MyClass().execute(messsage);
}
});

You cannot perform network IO on the UI thread on Honeycomb. Technically it is possible on earlier versions of Android, but is a really bad idea as it will cause your app to stop responding, and can result in the OS killing your app for being badly behaved. You'll need to run a background process or use AsyncTask to perform your network transaction on a background thread.
There is an article about Painless Threading on the Android developer site which is a good introduction to this, and will provide you with much better depth of answer than can be realistically provided here.
You have to put your code that access the internet on a thread
new Thread(new Runnable(){
#Override
public void run(){
//your code that access internet here
}
}).start();
try this code
package com.example.simpleclientactivity;
import java.io.IOException;
import java.io.PrintWriter;
import java.net.Socket;
import java.net.UnknownHostException;
import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class SimpleClientActivity extends Activity {
private Socket client;
private PrintWriter printwriter;
private EditText textField1;
private Button button;
private String messsage;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
textField1 = (EditText) findViewById(R.id.editText1); //reference to the text field
button = (Button) findViewById(R.id.button1); //reference to the send button
//Button press event listener
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Context context = getApplicationContext();
CharSequence text = "Hello toast!";
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, text, duration);
toast.show();
messsage = textField1.getText().toString(); //get the text message on the text field
textField1.setText(""); //Reset the text field to blank
new GetCategory().execute(message);
}
});
}
//add inner class
class GetCategory extends AsyncTask<Void, Void, ArrayList<AbstractDetail>>{
protected ArrayList<AbstractDetail> doInBackground(String... messsage) {
try {
client = new Socket("10.0.2.2", 4444); //connect to server
printwriter = new PrintWriter(client.getOutputStream(),true);
printwriter.write(messsage); //write the message to output stream
printwriter.flush();
printwriter.close();
client.close(); //closing the connection
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
protected void onPostExecute(ArrayList<AbstractDetail> result)
{
}
}
}
}
Problem
You can not access network over UI thread. You are accessing Network through UI thread that's why you are getting NetworkOnMainThreadException.
Solution
Create new thread and access Network over that Thread.
OR
Use AsyncTask to do network related work on doInBackgroung() and for updating UI onPostExecute().
I'm new in android environment and started a Software development project, so my knowledge is too few in it. I need help in detail.
Problem details:
Project is on ANDROID OCR code source from github Robert m.theis
currently it's outcome is - while i take an image of any written text,it retrieves quite exact output using tesseract engine as text and search in internet.
my work is -
use the text string (digits ) and call to a phone operator.
my project name is automated mobile card recharging system.
so that i took result text from a method getText() class named OcrResult.java and put into my own activity. But i don't know why this don't working in real device.
it builds, run in emulator, but in real device at least it should show messages! But it doesn't.
i also added in manifest.xml file as (angel braces are remover here)

I am having trouble connecting my android client to a C server that I wrote. I found another thread with a similar question but unfortunately it was closed saying that it was too narrow. I hope that somebody can answer it here since this is relevant to me as well and all sample codes that I could find online only had the android client connecting to an android server. My client code is the following:
package edu.upenn.seas.cis542;
import java.io.BufferedWriter;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.net.InetAddress;
import java.net.Socket;
import android.app.Activity;
import android.app.AlertDialog;
import android.os.Bundle;
import android.os.Debug;
import android.os.Handler;
import android.util.Log;
import android.view.Gravity;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;
public class Try_uiActivity extends Activity
{
//private EditText serverIp;
private Button connectPhones;
private String serverIpAddress = "MY IP ADDRESS";
private boolean connected = false;
private Handler handler = new Handler();
final int SERVERPORT = 8080;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
//NumberPicker t1 = (NumberPicker)findViewById(R.id.numberPicker3);
//t1.setRange(1, 5);
setContentView(R.layout.main);
}
/*
* When the Submit button is clicked, this method
* gets called.
*/
public void onSubmitClick(View view) {
int item1, item2, item3;
NumberPicker t1 = (NumberPicker)findViewById(R.id.numberPicker1);
item1 = t1.getCurrent();
NumberPicker t2 = (NumberPicker)findViewById(R.id.numberPicker2);
item2 = t2.getCurrent();
NumberPicker t3 = (NumberPicker)findViewById(R.id.numberPicker3);
item3 = t3.getCurrent();
String userInput = "" + item1 + item2 + item3;
//Log.out("Before connecting");
if (!connected) {
try {
InetAddress serverAddr = InetAddress.getByName(serverIpAddress);
Toast toast=Toast.makeText(this, serverAddr.toString(), Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
Socket socket = new Socket(serverAddr, SERVERPORT);
connected = true;
} catch (Exception e) {
Toast toast=Toast.makeText(this, "Error2", Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
e.printStackTrace();
connected = false;
}
}
}
}
I omitted what I want to do after it is connecting because just creating the socket already gives me an error. My C server opens a connection on the same port that the android program is connecting to. When I tested the server with a java client file, it worked fine. Does anybody know a solution to this? I also added the permissions to the Android Manifest, but that didn't solve the issue. Thanks!
i'm creating a login application
the login script is ok it's returned true and false
if the response returns true or 1, i want to make it to go to another activity called inputBarcode, the eclipse showing an error on my Intent line and i don't know what to do

Sorry for my bad english, i'm from Indonesia fyi :D
Did you make sure to add the inputBarCode activity to your AndroidManifiest? If you did not, then that will give a runtime error. If thats no the problem, then possibly changing
Intent doBarcode = new Intent(parent, inputBarcode.class);
to
Intent doBarcode = new Intent(this, inputBarcode.class);
will solve your problem. I'm not familiar with the parent variable being used.
I hope that helps.
Try instead of
Intent doBarcode = new Intent(parent, inputBarcode.class);
use this code:
Intent doBarcode = new Intent(login.this, inputBarcode.class);
I have a login page, it works fine when i put correct username and password but for login failure its not working how to handle this.
