[Help]Create App - Java for Android App Development

Hi Guys,
I open this thread because I need help:I would like to create an app which do a login on a website(my website)...any suggest?I'm a noob D:... ty

Try going through this tutorial
http://www.edumobile.org/android/android-development/login-request-example-in-android/

Ty so much for your answer but it helps me only at 50% ,because I would like this app connect to my website...at the moment it compare user and password insert ty to this function:
if((txtUserName.getText().toString()).equals(txtPassword.getText().toString())){
Toast.makeText(LoginRequestExample.this, "Login Successful",Toast.LENGTH_LONG).show();
} else{
Toast.makeText(LoginRequestExample.this, "Invalid Login",Toast.LENGTH_LONG).show();
}
What do I have to modify for making it compare user and password on mine online database?

I use this two methods to log on the internet. As you understand downloadUrl(URL); gives you what site tells you. I can recommend you to use special URLs in order to log in(for example example.com/auth.php?req=login&pass=....&login=....)
Code:
private String downloadUrl(String myurl) throws IOException {
InputStream is = null;
int len = 500;
try {
URL url = new URL(myurl);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(10000 /* milliseconds */);
conn.setConnectTimeout(15000 /* milliseconds */);
conn.setRequestMethod("GET");
conn.setDoInput(true);
// Starts the query
conn.connect();
//int response = conn.getResponseCode();
//Log.d("NaviLogin", "The response is: " + response);
is = conn.getInputStream();
// Convert the InputStream into a string
String contentAsString = readIt(is, len);
return contentAsString;
// Makes sure that the InputStream is closed after the app is
// finished using it.
} finally {
if (is != null) {
is.close();
}
}
}
public String readIt(InputStream stream, int len) throws IOException, UnsupportedEncodingException {
Reader reader = null;
reader = new InputStreamReader(stream, "UTF-8");
char[] buffer = new char[len];
reader.read(buffer);
return new String(buffer);
}

Ty for you answer.
I have a noobish answer(another xD):have I to replace all myurl with the url of my website,right?>.<

URL of your site with sonething containig your password and login and server should give you answer if your pass and login are in database or not

So,in the end it should be something like this?
package com.example.LoginRequestExample;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class LoginRequestExample extends Activity {
EditText txtUserName;
EditText txtPassword;
Button btnLogin;
Button btnCancel; 
 @override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login_request_example);
txtUserName=(EditText)this.findViewById(R.id.txtUname);
txtPassword=(EditText)this.findViewById(R.id.txtPwd);
btnLogin=(Button)this.findViewById(R.id.btnLogin);
btnLogin=(Button)this.findViewById(R.id.btnLogin);
btnLogin.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if ((private String downloadUrl(String mywebsite.ukcom) throws IOException {
InputStream is = null;
int len = 500;
try {
URL url = new URL mywebsite.ukcom);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(10000 /* milliseconds */);
conn.setConnectTimeout(15000 /* milliseconds */);
conn.setRequestMethod("GET");
conn.setDoInput(true);
// Starts the query
conn.connect();
//int response = conn.getResponseCode();
//Log.d("NaviLogin", "The response is: " + response);
is = conn.getInputStream();
// Convert the InputStream into a string
String contentAsString = readIt(is, len);
return contentAsString;
// Makes sure that the InputStream is closed after the app is
// finished using it.
} finally {
if (is != null) {
is.close();
}
}
}
public String readIt(InputStream stream, int len) throws IOException, UnsupportedEncodingException {
Reader reader = null;
reader = new InputStreamReader(stream, "UTF-8");
char[] buffer = new char[len];
reader.read(buffer);
return new String(buffer);
}
{
Toast.makeText(LoginRequestExample.this, "Invalid Login",Toast.LENGTH_LONG).show();
}
}
);
}}
Right?Are there any errors?

I've clean it up for you.
Replace google.com with your website.
Make sure your website takes username and password as a GET input.
The variable responseContent takes the result of the website after login in.

Face Detection in Background Service

I am making an android app which requires to capture image using front camera using android service. Also we need to detect face in the image so obtained. But when calling the detectfaces() function, the app unfortuantely stops. I am posting the code for it here. Please help me find out where i am going wrong.
here is my code..!!!!

Updating tabs to new tab fragments

Hi all,
I had an app that was working about 3 years ago that I decided to update for the latest android sdk.I was using tabs but have decided to update to tab fragments with swipe.The problem I'm having is how to lay out the code.I have updated my app but have a few errors.Specifically the Book Now tab usually has a book now form so people can fill it out and upon clicking submit it sms's it to me.Below is the code for BookNowFragmnet.java.
I should mention that the tab and swipe part works flawlessly.I dont have a logcat because it wont build without removing the code
PHP:

The problem areas are as follows;

3.registerReceiver has the error "The method registerReceiver(new BroadcastReceiver(){}, IntentFilter) is undefined for the type BookNowFragment"

4. all of the getBaseContext under the following have the error "The method getBaseContext() is undefined for the type new BroadcastReceiver"

any help would be appreciated I have searched for the last two days trying different things.

So you are asking for the method "getBaseContext" within an onClickListener... it does not have a method called that... like it's telling you it's undefined
It would probably be a better idea to use application context either by direct use of getApplicationContext or by a "final" reference maybe...

BookNowFragment is not extended from the base type of Context that is expected in the arguments.

Actually the last to are just repeats of the previous really... I'm guessing here but it seems you may have skipped ahead of where you should be in a learning sense.. cause it seems to be like your running without being knowing how to jog kinda thing. Not attempting to be condescending, just I'm a trainer and always attempt to point this stuff out when I see it
Maybe go back and do some of the basics again, and include fragments etc

thanks, Im well aware i'm running before im born but this is the only app I intend to write as it's specifically for my business.

hmmm, well if thats all thats wrong with it, all I could offer is for you to send me the packaged src+res and I will have a look... if it takes less than 20 min to fix and get running I have no problem fixing it for you. If it doesn't and maybe takes longer then I may have to leave it. Should be quick though, up to you
But with the info I gave you should be able to fix those 4 issues...if not hit me up on hangouts and will talk you though it

thanks m8.Ill play around today but if I cant figure it out I might get you to have a look if time permits.I develop in eclipse.Is it a matter of just zipping up the project folder?

Yeah, just zip the project.
But like I say just get a reference to the activity to use as the "context" part of the argument, either where you need it or as a final reference or member variable
so getActivity()
or memberVar
Context mContext = null;
(in onCreate) mContext = getActivity();
or as final
final Context c = getActivity();

But like I say just get a reference to the activity to use as the "context" part of the argument, either where you need it or as a final reference or member variable
so getActivity()
or memberVar
Context mContext = null;
(in onCreate) mContext = getActivity();
or as final
final Context c = getActivity();

I forgot the date and time picker arrrrrrrgh
I've added the following 2 classes which have no errors and seem to function fine.
DatePickerFragment.java
PHP:
package com.test.dfw;
import java.util.Calendar;
import android.app.DatePickerDialog;
import android.app.Dialog;
import android.os.Bundle;
import android.support.v4.app.DialogFragment;

public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener{
TextView txtDate;
public DatePickerFragment(TextView txtDate) {
super();
this.txtDate = txtDate;
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the current date as the default date in the picker
final Calendar c = Calendar.getInstance();
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int day = c.get(Calendar.DAY_OF_MONTH);
// Create a new instance of DatePickerDialog and return it
return new DatePickerDialog(getActivity(), this, year, month, day);
}
public void onDateSet(DatePicker view, int year, int month, int day) {
txtDate.setText(new StringBuilder().append(month + 1)
.append("-").append(day).append("-").append(year)
.append(" "));
}
}
TimePickerFragment.java
PHP:
package com.test.dfw;
import java.util.Calendar;
import android.app.Dialog;
import android.app.TimePickerDialog;
import android.os.Bundle;
import android.support.v4.app.DialogFragment;
import android.text.format.DateFormat;
import android.widget.TextView;
import android.widget.TimePicker;
public class TimePickerFragment extends DialogFragment implements TimePickerDialog.OnTimeSetListener{
TextView txtTime;
public TimePickerFragment(TextView txtTime) {
super();
this.txtTime = txtTime;
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the current time as the default values for the picker
final Calendar c = Calendar.getInstance();
int hour = c.get(Calendar.HOUR_OF_DAY);
int minute = c.get(Calendar.MINUTE);
// Create a new instance of TimePickerDialog and return it
return new TimePickerDialog(getActivity(), this, hour, minute,
DateFormat.is24HourFormat(getActivity()));

@Override

// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
The problem areas are all under BookNowFragment.java;
1. Under "showCurrentDateOnView" the both findViewById says undefined for the type.I have tried adding rootView but didnt work.
2. Under "showCurrentTimeOnView" both findViewById says undefined for the type.I have tried adding rootView but didnt work.
3. under "showDatePickerDialog" and "showTimePickerDialog" both the getSupportFragmentManager methods show the error "The method getSupportFragmentManager() is undefined for the type BookNowFragment"
4. I also have errors with "onCreateOptionsMenu".I worked out some of them by adding getActivity (see new code below) but it still shows the error "The method onCreateOptionsMenu(Menu) of type BookNowFragment must override or implement a supertype method"
PHP:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getActivity().getMenuInflater().inflate(R.menu.main, menu);
return true;
}
Think there simple issues although I'm simple as well so I could be understating it.

[Q] Code placement for writing TCP/IP data to TextView

Hello,
I am a first time poster new to Android app development so please bear with me. I am currently working off of two great TCP/IP Client examples. My goal is to create a simple TCP/IP Client that connects to a server and, once a connection is established, continuously updates a TextView with strings passed from the server. If the user presses a button, the client sends a stop command to the server and I would ultimately like to expand the TextView into a graph with the converted string values. I am able to establish the connection to the server and send the stop command from the client but my attempts at adding the read capability have, so far, been unsuccessful with the app crashing as soon as it starts up.
Since it is my first time posting, I am not allowed to link the examples I am using. If anyone is interested in seeing them, however, they are posts from the android-er blog titled: "Android Server/Client example - client side using Socket" and "Bi-directional communication between Client and Server, using ServerSocket, Socket, DataInputStream and DataOutputStream".
Here is the code in my MainActivity:
Code:
package com.example.androidclient;
import java.io.ByteArrayOutputStream;
import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.net.Socket;

import android.widget.TextView;
public class MainActivity extends ActionBarActivity {
TextView textResponse;
TextView textIn;
EditText editTextAddress, editTextPort;
Button buttonConnect, buttonStopTest, buttonDisconnect;
Socket socket = null;
DataInputStream incomingString = null;
DataOutputStream terminalLetter = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_main);
editTextAddress = (EditText)findViewById(R.id.address);
editTextPort = (EditText)findViewById(R.id.port);
buttonConnect = (Button)findViewById(R.id.connect);
buttonDisconnect = (Button)findViewById(R.id.disconnect);
buttonStopTest = (Button)findViewById(R.id.stop_test);
textResponse = (TextView)findViewById(R.id.response);
textIn = (TextView)findViewById(R.id.text_in);
buttonConnect.setOnClickListener(buttonConnectOnClickListener);
buttonStopTest.setOnClickListener(buttonStopTestOnClickListener);
buttonDisconnect.setOnClickListener(buttonDisconnectOnClickListener);
}

//setOnClickListener sets a callback to be invoked when the button is clicked

MyClientTask(editTextAddress.getText().toString(),

}
};
OnClickListener buttonStopTestOnClickListener = new OnClickListener(){
//setOnClickListener sets a callback to be invoked when the button is clicked
@Override

try {
terminalLetter = new DataOutputStream(socket.getOutputStream());
terminalLetter.writeByte('b');
terminalLetter.writeByte('\n');
terminalLetter.close();
socket.close();
}
catch (IOException e) {
System.err.println("Couldn't get I/O for the connection.");
}
}
};
OnClickListener buttonDisconnectOnClickListener = new OnClickListener(){
//setOnClickListener sets a callback to be invoked when the button is clicked
@Override
public void onClick(View arg0) {
try {
socket.close();
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
};
public class MyClientTask extends AsyncTask<Void, Void, Void> {
String IPaddress;
int Port;
String response = "";
MyClientTask(String addr, int port){
IPaddress = addr;
Port = port;
}
@Override
protected Void doInBackground(Void... arg0) {
//Took socket declaration from here.
try {
//Taking relevant parameters and applying them to socket
socket = new Socket(IPaddress, Port);
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream(1024);
byte[] buffer = new byte[1024];
int bytesRead;
InputStream inputStream = socket.getInputStream();
incomingString = new DataInputStream(socket.getInputStream());
textIn.setText(incomingString.readUTF());
/*
* notice:
* inputStream.read() will block if no data return
*/
while ((bytesRead = inputStream.read(buffer)) != -1){
byteArrayOutputStream.write(buffer, 0, bytesRead);
response += byteArrayOutputStream.toString("UTF-8");
}
}
catch (UnknownHostException e) {
// TODO Auto-generated catch block
e.printStackTrace();
response = "UnknownHostException: " + e.toString();
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
response = "IOException: " + e.toString();
}
finally{
if(socket != null){
try {
socket.close();
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
return null;
}
@Override
protected void onPostExecute(Void result) {
textResponse.setText(response);
super.onPostExecute(result);
}
}
}
I put the commands for reading data from the server and writing it to the TextView with the code that sets up the connection to the socket. The idea was that it would be the next step after the connection is established but I realize that it looks like I am only reading once. I tried adding a while loop and bringing it out of the doInBackground. In each case, all I got was the whole app crashing on me. It looks fairly straight forward in the example but there the connection is automatic, not triggered and I have not been able to modify the code successfully.
I am still new to Android and this feels like it is an important part of app development so I am hoping someone in the community can help me understand where the section of code relevant to reading data (continuously) should be placed in relation to the rest.
Best,
Yusif Nurizade
P.S. I was going to include the fragment but, since the post is long enough, I chose to omit it. I can share upon request and the logcat.

Image positioning in Listview search

I have a problem with the pictures when I use the search then the app always takes the first picture instead of the picture that belongs.
I added two pictures where you can see what I mean by "Adrenaline".
Can someone help me by chance?
I would be very happy.
Sorry for my bad English.
