How to save zxing barcode scan results to a database?

I'm working on a project that takes student attendance using a camera based barcode scanner. i'm using zxing as a barcode canner. i followed instructions on a web page and created a package and added two files called IntentResult.java and IntentIntegrater.java
these are the files.
intentResult.java
package google.zxing.integration.android;
public final class IntentResult {
private final String contents;
private final String formatName;
private final byte[] rawBytes;
private final Integer orientation;
private final String errorCorrectionLevel;
IntentResult() {
this(null, null, null, null, null);
}
IntentResult(String contents,
String formatName,
byte[] rawBytes,
Integer orientation,
String errorCorrectionLevel) {
this.contents = contents;
this.formatName = formatName;
this.rawBytes = rawBytes;
this.orientation = orientation;
this.errorCorrectionLevel = errorCorrectionLevel;
}
public String getContents() {
return contents;
}
public String getFormatName() {
return formatName;
}
public byte[] getRawBytes() {
return rawBytes;
}
public Integer getOrientation() {
return orientation;
}
public String getErrorCorrectionLevel() {
return errorCorrectionLevel;
}
#Override
public String toString() {
StringBuilder dialogText = new StringBuilder(100);
dialogText.append("Format: ").append(formatName).append('\n');
dialogText.append("Contents: ").append(contents).append('\n');
int rawBytesLength = rawBytes == null ? 0 : rawBytes.length;
dialogText.append("Raw bytes: (").append(rawBytesLength).append(" bytes)\n");
dialogText.append("Orientation: ").append(orientation).append('\n');
dialogText.append("EC level: ").append(errorCorrectionLevel).append('\n');
return dialogText.toString();
}
}

Toast toast = Toast.makeText(this, "Content:" + contents + " Format:" + format, Toast.LENGTH_LONG);
toast.show();
}
}
}
}
I didn't make the zxing as a library. If i should tell me. At the moment when you first run the app it make you download a barcode scanner from google store.
I hope this is enough. If you need any more information let me know. Thanks in advance

Custom Login with Twitter in android

How to create custom buttons for social login auth for twitter on android application development. By default social media have different SDK, which SDK twitter already has its own button social login but i want to use my own custom button and i wrote some code but getting exception
java.lang.NullPointerException: Attempt to invoke virtual method 'int java.lang.Object.hashCode()' on a null object reference
my code:-
TwitterConfig config = new TwitterConfig.Builder(this)
.logger(new DefaultLogger(Log.DEBUG))
.twitterAuthConfig(new TwitterAuthConfig("KEY",
"KEY"))
.debug(true)
.build();
Twitter.initialize(config);
client = new TwitterAuthClient();
final TwitterSession session = TwitterCore.getInstance().getSessionManager().getActiveSession();
twitterButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
client.requestEmail(session, new Callback<String>() {
#Override
public void success(Result<String> result) {
System.out.println("Email is=====>" + result.data);
}
#Override
public void failure(TwitterException exception) {
}
});
}
});

please try this
add this gradle line in you project
compile 'com.twitter.sdk.android:twitter:3.0.0'
Write in your Activity/Fragment
//Your Custom Button
private ivTwitter;
//Twitter Login Button
private TwitterLoginButton ivTwitterMain;
//init twitter
TwitterConfig config = new TwitterConfig.Builder(this)
.logger(new DefaultLogger(Log.DEBUG))
.twitterAuthConfig(new TwitterAuthConfig(Const.CONSUMER_KEY, Const.CONSUMER_SECRET))
.debug(false)
.build();
Twitter.initialize(config);
//Write in onCreate method
ivTwitter = (ImageView) view.findViewById(R.id.ivTwitter);
ivTwitterMain = (TwitterLoginButton)view.findViewById(R.id.ivTwitterMain);
ivTwitterMain.setCallback(new Callback<TwitterSession>() {
#Override
public void success(Result<TwitterSession> result) {
// Do something with result, which provides a TwitterSession for making API calls
TwitterSession session = TwitterCore.getInstance().getSessionManager().getActiveSession();
TwitterAuthToken authToken = session.getAuthToken();
String token = authToken.token;
String secret = authToken.secret;
getTwitterUserProfile(session);
}
#Override
public void failure(TwitterException exception) {
// Do something on failure
Log.d(Const.FRAGMENT_REGISTER, exception.getMessage());
}
});
//getTwitterUserProfile
private void getTwitterUserProfile(TwitterSession session) {
AccountService accountService = new TwitterApiClient(session).getAccountService();
Call<User> callback = accountService.verifyCredentials(true, true, true);
callback.clone().enqueue(new Callback<User>() {
#Override
public void success(Result<User> result) {
Log.d("NAME ", result.data.name);
Log.d("EMAIL", result.data.email);
Log.d("PICTURE ", result.data.profileImageUrl);
}
#Override
public void failure(TwitterException exception) {
}
});
}
at last generate Click event of custom button
ivTwitter.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//twitter login button
ivTwitterMain.performClick();
}
});

WebRTC Android Library function not getting called

I am using the following open-source webrtc android application:
https://github.com/pchab/AndroidRTC
I have just modified this application to use my socket.io server instead of using the following one which is given by same author:
https://github.com/pchab/ProjectRTC
To do this, I needed to do some changes in the two classes of the above AndroidRTC Application. After this, when I started the application it did not call the 'createOffer()' or 'createAnswer()' function which is part of libjingle_peerconnection library. I am confused whether these two functions are not getting called or they are not able to use 'sendMessage()' function.
From debugging, I came to know that line which calls 'createAnswer()' function is successfully reached. After this, I expect the 'createAnswer()' function to use my 'sendMessage()' function to send the answer back to other party by using my socket.io server. I am not able to peek inside this 'createAnswer()' function as it is part of the library.
Before changing the above application to use my own server, I had tested it with the server given by auhtor. It ran successfully. I don't know what is wrong when I use my own server to make calls and do handshaking. I just modified few lines to support the way I do signalling on the server.
My server code is already used for webrtc web application. Web Applications are successful in making calls using this server. It should work for this android application too with little modification on the application.
I modified the following two classes in android application:

The code is able to receive the offer and candidates from other party. It is not able to send the answer or candidates to that party in return.
I have not modified other two classes which can be found on the above link for android application.
Here is snippet of my socket.io server code written in nodejs:
socket.on('create or join livehelp', function (room) {
var numClients = socketio.sockets.clients(room.room).length;
if (numClients === 0){
socket.join(room.room);
socket.set('nickname', room.username);
socket.emit('created', room);
} else if (numClients < 2) {
socket.join(room.room);
socket.set('nickname', room.username);
socket.emit('joined', room);
socket.broadcast.to(room.room).emit('join', room);
} else { // max three clients
socket.emit('full', room.room);
}
console.log(socketio.sockets.manager.rooms)
console.log(room)
});
socket.on('message', function (message) {
//console.log('Got message:', message);
//socket.broadcast.emit('message', message);
message.msg.from = socket.id;
//socketio.sockets.in(message.room).emit('message', message.msg);
socket.broadcast.to(message.room).emit('message', message.msg);
//console.log('Got message:', message.msg);
//console.log(socketio.sockets.manager.rooms)
});
I am confused if there is any error why I am not able to find it in debugging. Log for this is very difficult to read as it runs very fast and I am not able to catch each and every line. But apparently, it looked fine at a glance.
Please help. Thanks.

I think you are not able to generate answer but you are able to generate offer?. If this is the case try adding
pcConstraints.optional.add(new MediaConstraints.KeyValuePair("DtlsSrtpKeyAgreement", "true"));
to your pc constraints.

Hope this will help..
client.on('message', function (details) {
console.log('message',details.to);
console.log(details.type);
if(details.type !== 'init'){
var otherClient = io.sockets.connected[details.to];
if (!otherClient) {
return;
}
delete details.to;
details.from = client.id;
otherClient.emit('message', details);
}
else
{
if (io.sockets.adapter.rooms[client.room] !== undefined ) {
for(var member in io.sockets.adapter.rooms[client.room]){
console.log(member);
if(member !== client.id){
var otherClient = io.sockets.connected[member];
if (!otherClient) {
return;
}
delete details.to;
details.from = client.id;
otherClient.emit('message', details);
}
else{
console.log("no need to send self again!");
}
}
} else {
client.emit("update", "Please connect to a room.");
}
}
});

Improve this question
I am having a problem with a task that shows live content from a site.
I have been playing around with this code for a while and playing around with the status but I can't seem to get it to work correctly.
The only solution I have been able to come up with so far is completely disable orientation changes, but I would prefer not to do that if possible.

Easy Facebook Android SDK - NetworkOnMainThreadException

I have been Using this SDK http://www.easyfacebookandroidsdk.com/ to integrate Facebook in my App.
I only want to update a statur from my App. It worked great using this class in Android API 10. Running it on phone with API 15 gives me a android.os.NetworkOnMainThreadException. here my code:
package com.my.wod;
import android.app.Activity;
import android.content.Context;
import com.main.xfit.R;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.Window;
import android.widget.Toast;
import com.facebook.android.*;
import com.facebook.android.Facebook.DialogListener;
public class PostFaceBookStatus extends Activity {
private static final String APP_ID = "ID OF MY APP";
private static final String[] PERMISSIONS = {"publish_stream" };
private static final String TOKEN = "access_token";
private static final String EXPIRES = "expires_in";
private static final String KEY = "facebook-credentials";
private Facebook facebook;
private String messageToPost;
public boolean saveCredentials(Facebook facebook) {
Editor editor = getApplicationContext().getSharedPreferences(KEY, Context.MODE_PRIVATE).edit();
editor.putString(TOKEN, facebook.getAccessToken());
editor.putLong(EXPIRES, facebook.getAccessExpires());
return editor.commit();
}
public boolean restoreCredentials(Facebook facebook) {
SharedPreferences sharedPreferences = getApplicationContext().getSharedPreferences(KEY, Context.MODE_PRIVATE);
facebook.setAccessToken(sharedPreferences.getString(TOKEN, null));
facebook.setAccessExpires(sharedPreferences.getLong(EXPIRES, 0));
return facebook.isSessionValid();
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
facebook = new Facebook(APP_ID);
restoreCredentials(facebook);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.facebook);
String facebookMessage = getIntent().getStringExtra("facebookMessage");
Toast.makeText(getApplicationContext(), facebookMessage, Toast.LENGTH_LONG).show();
if (facebookMessage == null){
facebookMessage = "SUNDAY 120506 2012 CrossFit Games Regional: Individual Event 4 For time: 135 pound Back squat, 50 reps 40 Pull-ups 135 pound Shoulder-to-overhead, 30 reps 85 pound Front squat, 50 reps 40 Pull-ups 85 pound Shoulder-to-overhead, 30 reps 65 pound Overhead squat, 50 reps 40 Pull-ups 65 pound Shoulder-to-overhead, 30 reps";
}
//messageToPost = facebookMessage;
messageToPost = "Post random shit" ;
}
public void doNotShare(View button){
finish();
}
public void share(View button){
if (! facebook.isSessionValid()) {

}
else {

if (response == null || response.equals("") ||

showToast("Blank response.");
}
else {
showToast("Message posted to your facebook wall!");
}
finish();
} catch (Exception e) {
showToast("Failed to post to wall!");
e.printStackTrace();
finish();
}
}
class LoginDialogListener implements DialogListener {
public void onComplete(Bundle values) {

if (messageToPost != null){
postToWall(messageToPost);
}
}
public void onFacebookError(FacebookError error) {

finish();
}
public void onError(DialogError error) {

public void onCancel() {
showToast("Authentication with Facebook cancelled!");
finish();
}
}
private void showToast(String message){
Toast.makeText(getApplicationContext(), message, Toast.LENGTH_SHORT).show();
}
}
Any ideas?

You can't run network operations on the UI thread, and if you think it is is the API code doing it, then you'll have to wrap the API call's in a Thread.
Looks like this line is using the network:
String response = facebook.request("me/feed", parameters, "POST");
You need to do long running tasks on a worker thread.
You used to get an ANR (Activity Not Responsding) but ICS is a little cleverer and kicks you off before this happens.

http://developer.android.com/guide/practices/responsiveness.html
http://developer.android.com/training/basics/network-ops/connecting.html#AsyncTask < This is one possible alternative answer

To make it work for API level 10 and higher i just employed and AsyncTask and it Worked!!
Use the below code:
//make this global declaration
private Facebook mFacebook;
private class FbLoginAsync extends AsyncTask<Void, Void, User> {
#Override
protected void onPreExecute() {
super.onPreExecute();
showDialog(ConstantsCtc.DIALOG_PROGRESS);
}
#Override
protected User doInBackground(Void... params) {
// facebooklogin();
return getFacebookData();
}
#Override
protected void onPostExecute(User u) {
super.onPostExecute(u);
// your facebook information is in User bean 'u'.
}
}
public User getFacebookData() {
User u = new User();
try {
JSONObject jsonME = null;
JSONObject jsonfrnd = null;
try {
jsonME = Util.parseJson(mFacebook.request("me"));
// jsonfrnd =
// Util.parseJson(mFacebook
// .request("me/friends"));
} catch (FacebookError e) {
e.printStackTrace();
u = null;
}
Log.w("fbjsonMe", " *\n " + jsonME);
// Log.e("fbjsonfrnds", " *\n " + jsonfrnd);
String mUserId = jsonME.getString("id");
String mUserName = jsonME.getString("first_name");
String mUseremail = jsonME.getString("email");
String birthday = jsonME.getString("birthday");
String gender = jsonME.getString("gender");
String full_name = jsonME.getString("name");
// Log.w("UserName", mUserName + " * " + mUseremail + " *\n "
// + jsonME);
// calculate age
String ag[] = birthday.split("/");
int y = Integer.parseInt(ag[2]);// get birth year
final Calendar cal = Calendar.getInstance();
int currentyear = cal.get(Calendar.YEAR);
int age = currentyear - y;
if (gender.equalsIgnoreCase("male"))
gender = "0";
else
gender = "1";
u.setUserId(mUserId);
u.setUserFullName(full_name);
u.setEmail(mUseremail);
u.setAge(age + "");
u.setGender(gender);
} catch (Exception e) {
e.printStackTrace();
u = null;
}
return u;
}
// then make a call to below method form your activity's button click or
// else
public void facebookLogin() {
this.mFacebook = new Facebook(appId);// give your appId
if (mFacebook.isSessionValid()) {
new FbLoginAsync().execute();
} else {
SessionEvents.AuthListener listener = new SessionEvents.AuthListener() {
#Override
public void onAuthSucceed() {
new FbLoginAsync().execute();
}
#Override
public void onAuthFail(String error) {
showDialogCustome("Error in Facebook Login, please try again later");
Log.e("onAuthFail", "onAuthFail");
}
};
SessionEvents.addAuthListener(listener);
mFacebook.authorize(this.activity, this.permissions,
Facebook.FORCE_DIALOG_AUTH, new LoginDialogListener());
}
}
I hope this solves your problem. let me know
