I am developing an app in java in the android studio IDE, the idea is that after logging in with my username and password, I can be redirected to a new view where a user profile is shown with the name, email and profile image. Currently I can log in and after that it redirects to the user profile but I don't know how to get the name, email and profile image.Then I leave you my code in case you have the time to help me, thank you very much for reading:

I have a login activity that works fine,after successfully login i get token which i send it to the webview fragment by SharedPreferences and pass it to WebviewClient but it doesn't redirect to the homepage URL of the site which is inside webview,it's redirect to login page URL of the site inside Webview.I didn't find helpful solution.
Thanks in advance

Log.d("ResponseToken", "" + response.getSuccess().getToken());
if (response.getSuccess() != null) {
String token = response.getSuccess().getToken();
setKeyToken(token);
Intent intent = new Intent(LoginActivity.this,MainActivity.class);

Sorry new to SOF and my question might seem a bit vague.
Using android studio, i'd like to be able to upload an audio file and a text file generated from the audio file, to firebase. They are linked, however I can only upload the audio file to the firebase realtime-database. Is there any way to combine the .3gp file and the .txt file and upload them? Thanks.
Edited: This is my code so far. It's quite messy just trying to get the files together. Thanks.

You can write and apply below mentioned steps (Please ignore any syntactical error, I am giving you simple logical steps).
step 1 - Make a global application level loginObject setter and getter like below. Make sure to define Application class in your manifest just like you do it for your LoginActivity
public class ApplicationClass extends Application{
private LoginBean loginObject;
public void setLoginBean(LoginBean object) {
this.loginObject = object;
}
public LoginBean getName() {
return this.loginObject
}
}
Step - 2 Get an instance of ApplicationClass object reference in LoginActivity to set this global loginObject
e.g. setLogin object in your current Loginactivity like this
......
private ApplicationClass appObject;
......
#Override
protected void onCreate(Bundle savedInstanceState) {
......
appObject = (ApplicationClass) LoginActivity.this.getApplication();
.......
appObject.setLoginBean(loginObject)
}
Step - 3 Get an instance of ApplicationClass object reference in any other Activity get this global loginObject where you need to access this login data.
e.g. getLogin object in your otherActivity like this
......
private ApplicationClass appObject;
......
#Override
protected void onCreate(Bundle savedInstanceState) {
......
appObject = (ApplicationClass) LoginActivity.this.getApplication();
.......
LoginBean loginObject = appObject.getLoginBean();
}
I am trying to develop my own Android application using Android Studio 0.4.2 and the Twitter4J library. My idea is to use a WebView to load there the Twitter authentication page and get the AccessToken from there. I can get the oauth_token and oauth_verifier, but after that all the Twitter methods to get followers, post twits, whatever are not working.
This is my code:
public class TwitterLoginFragment extends Fragment {
private static String TWITTER_CONSUMER_KEY = "***";
private static String TWITTER_CONSUMER_SECRET = "***";
private static final String TWITTER_CALLBACK_URL = "http://www.hita.pro";
private static SharedPreferences sharedPreferences;
private Button btnTwitterLogin;
private Button btnTwitterLogOut;
private WebView wvTwitterLogin;
private IDs iDs;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
sharedPreferences = getActivity().getSharedPreferences("CONNECTION_INFO", Context.MODE_PRIVATE);
TwitterFactory.getSingleton().setOAuthConsumer(TWITTER_CONSUMER_KEY, TWITTER_CONSUMER_SECRET);
return inflater.inflate(R.layout.fragment_twitter_login, container, false);
}
#Override
public void onActivityCreated(Bundle savedInstance) {
super.onActivityCreated(savedInstance);
wvTwitterLogin = (WebView) getView().findViewById(R.id.wvTwitterLogin);
wvTwitterLogin.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putBoolean("KEY_TWITTER_LOGIN", true);
editor.putString("OAUTH_TOKEN", url.substring(url.indexOf("oauth_token=") + 12, url.indexOf("&")));
editor.putString("OAUTH_VERIFIER", url.substring(url.indexOf("oauth_verifier=") + 15));
editor.commit();
TwitterFactory.getSingleton().setOAuthAccessToken(new AccessToken(sharedPreferences.getString("OAUTH_TOKEN", ""), sharedPreferences.getString("OAUTH_VERIFIER", "")));
new GetTwitterFollowers().execute();
return true;
}
});
btnTwitterLogin = (Button) getView().findViewById(R.id.btnTwitterLogin);
btnTwitterLogin.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
loginToTwitter();
}
});
btnTwitterLogOut = (Button) getView().findViewById(R.id.btnTwitterLogOut);
btnTwitterLogOut.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
twitterLogOut();
}
});
}
public void loginToTwitter() {
if (!isTwitterLoggedInAlready()) {
Thread thread = new Thread(new Runnable() {
#Override
public void run() {
try {
wvTwitterLogin.loadUrl(TwitterFactory.getSingleton().getOAuthRequestToken(TWITTER_CALLBACK_URL).getAuthenticationURL());
getActivity().runOnUiThread(new Runnable() {
#Override
public void run() {
goToTwitterLogin();
}
});
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(getActivity(), getString(R.string.error_already_logged_twitter), Toast.LENGTH_LONG).show();
}
}
});
thread.start();
} else
Toast.makeText(getActivity(), getString(R.string.error_already_logged_twitter), Toast.LENGTH_LONG).show();
}
private void goToTwitterLogin() {
btnTwitterLogin.setVisibility(View.GONE);
btnTwitterLogOut.setVisibility(View.GONE);
wvTwitterLogin.setVisibility(View.VISIBLE);
}
private boolean isTwitterLoggedInAlready() {
return sharedPreferences.getBoolean("KEY_TWITTER_LOGIN", false);
}
private void twitterLogOut() {
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putBoolean("KEY_TWITTER_LOGIN", false);
editor.commit();
}
private class GetTwitterFollowers extends AsyncTask<Void, Void, Void> {
#Override
protected Void doInBackground(Void... v) {
try {
iDs = TwitterFactory.getSingleton().getFollowersIDs(-1);
} catch (TwitterException e) {
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(Void result) {
iDs.getIDs();
}
}
}
When I call to TwitterFactory.getSingleton().getFollowersIDs(-1) after the user has singed in, I'm getting this exception:
java.io.IOException: No authentication challenges found
I'm desperated, I have spent one week trying to solve this problem but all the threads I have found in StackOverflow and other sites are not working. The system clock is OK, I have tried with ConfigurationBuilder and other solutions, but no luck. Can somebody help me?
Thanks a lot!
Have you tried to work with instance not singleton from TwitterFactory?
Uri uri = Uri.parse(url);
String token = uri.getQueryParameter("OAUTH_TOKEN");
String verifier = uri.getQueryParameter("OAUTH_VERIFIER");
Twitter twitter = TwitterFactory.getInstance(
new AccessToken(token,verifier);
twitter.getFollowers(-1);
