Asyntask not executing onPostExecute()

Asyntask not executing onPostExecute() - android

This is my Asyntask code which is not firing the onPostExecute() Any one has any idea why this might be happening???
EDIT: The Asyntask is called this way
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(getApplicationContext());
callbackManager = CallbackManager.Factory.create();
setContentView(R.layout.activity_main);
.
.
textView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(getApplicationContext(), SignUp.class);
startActivity(intent);
}
});
textView2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(getApplicationContext(), Feedback.class);
startActivity(intent);
}
});
fbLoginButton = (LoginButton) findViewById(R.id.login_button);
fbLoginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
token=loginResult.getAccessToken().getToken().toString();
Log.v("tag", "Token:\n" + token);
try {
get_profile();
}catch (Exception ex) {
String error = ex.getMessage();
}
}
#Override
public void onCancel() {
Toast.makeText(MainActivity.this, "Login cancelled by user!", Toast.LENGTH_LONG).show();
System.out.println("Facebook Login failed!!");
}
#Override
public void onError(FacebookException e) {
Toast.makeText(MainActivity.this, "Login unsuccessful!", Toast.LENGTH_LONG).show();
System.out.println("Facebook Login failed!!");
}
});
}
The get_profile(); method is defined like this
//Method to get profile details
public void get_profile() throws UnsupportedEncodingException {
try {
// Calling async task to get json
new FetchOperation().execute();
} catch (Exception e) {
e.printStackTrace();
}
}
This is inside the Main class too
//Asynctask to get Getting fb profile details
private class FetchOperation extends AsyncTask<Void, Void, String> {
String fb_token;
#Override
protected void onPreExecute() {
super.onPreExecute();
// Get user defined values
fb_token = token;
}
#Override
protected String doInBackground(Void... params) {
String response = "";
String Urls = "https://graph.facebook.com/me?access_token=";
HttpClient httpclient = new DefaultHttpClient();
HttpGet httpget = new HttpGet(Urls +token);
HttpEntity httpEntity = null;
HttpResponse httpResponse = null;
try {
httpResponse = httpclient.execute(httpget);
} catch (ClientProtocolException e) {
e.printStackTrace();
Log.v("Response", "Hi From e1 : " + e.toString());
} catch (IOException e) {
e.printStackTrace();
}
try {
httpEntity = httpResponse.getEntity();
response = EntityUtils.toString(httpEntity);
Log.v("Response", "Hi From 2 : "+response.toString());
return response;
} catch (IOException e) {
e.printStackTrace();
Log.v("Response", "Hi From e2 : " + e.toString());
}
return null;
}
#Override
protected void onPostExecute(String jsonStr) {
super.onPostExecute(jsonStr);
Log.v("tag", "Result:" + jsonStr);
if (jsonStr != null) {
try{
JSONObject jsonObj = new JSONObject(jsonStr);
String email = jsonObj.getString("email");
String firstName = jsonObj.getString("first_name");
String lastName = jsonObj.getString("last_name");
String gender = jsonObj.getString("gender");
String country = jsonObj.getString("locale");
id = jsonObj.getString("id");
user = firstName.concat(" ");
user = user.concat(lastName);
image = "http://graph.facebook.com/" + id + "/picture?type=large";
Log.v("Fb name", "Bla bla Name : " + user);
new UploadOperation().execute();
}
catch (JSONException e) {
e.printStackTrace();
}
}
else {
Log.e("ServiceHandler", "Couldn't get any data from the url");
}
}
}
This is the last lines of the logcat
06-29 14:30:49.927 2091-2091/com.example.kmi_dev.fbloginsample V/tag﹕ Token:
CA****************************************************************xr

06-29 14:31:23.827 2091-2098/com.example.kmi_dev.fbloginsample W/art﹕ Suspending all threads took: 10ms
I intend to fire another asyntask which will then save the data fetched by this asyntask into the database.

Make these changes, it will work -
private class FetchOperation extends AsyncTask<Void, Void, String>
change to - private class FetchOperation extends AsyncTask<Void, String, String> , because, you are trying to return String.
response = EntityUtils.toString(httpEntity);
change to - response = EntityUtils.toString(httpEntity).toString();
at the next line of this you have actually done it.
At the very end of doInBackground method where return null;
change to - return response;
4.No need to call super in onPostExecute()
5.Inside onPostExecute() check jsonStr is null or not and do whatever you want to do if null and if contains json data.

Your JSONObject does not contain a JSONString "email", so it is falling over at line
String email = jsonObj.getString("email");
and going straight to catch block.

I just used the second code to test the trasaction. But i have to use the first posted code because i have to post the ORDERID and CALLBACKURL from android application to server . Any help would be appreciable.

**Here is the solution for all :**
Be sure to send equal number of parameters to your server (For checksum generator) And then to paytm server for payment.
**For example:**
If you are sending 6 params for checksum generator, then send these 6 same parameters including Checksum to Paytm...
It will resolve your problem.
**CODE EXAMPLE :**
**Generate checksum.php**
$paramList = array();
$paramList["MID"] = 'Provided by Paytm'; //Provided by Paytm
$paramList["ORDER_ID"] = 'hIquwhzvzTG7gvT'; //unique OrderId for every request
$paramList["CUST_ID"] = 'CUST0001453'; // unique customer identifier
$paramList["INDUSTRY_TYPE_ID"] = 'Retail'; //Provided by Paytm
$paramList["CHANNEL_ID"] = 'WAP'; //Provided by Paytm
$paramList["TXN_AMOUNT"] = '10.00'; // transaction amount
$paramList["WEBSITE"] = 'APP_STAGING';//Provided by Paytm
$paramList["CALLBACK_URL"] = 'https://pguat.paytm.com/paytmchecksum/paytmCallback.jsp';
**Android Activity.java**
paramMap.put("MID" , "#########");
paramMap.put( "ORDER_ID" , "hIquwhzvzTG7gvT");
paramMap.put( "CUST_ID" , "CUST0001453");
paramMap.put( "CHANNEL_ID" , "WAP");
paramMap.put( "TXN_AMOUNT" , "10.00");
paramMap.put( "WEBSITE" , "APP_STAGING");
paramMap.put( "CALLBACK_URL" , "https://pguat.paytm.com/paytmchecksum/paytmCallback.jsp");
paramMap.put( "CHECKSUMHASH" , "dR5OtEkuNkgamHTZDCHmF+CF3j9RdG1520mlHEb85oSZP1CaxVUsRY2sYric90HLm/vElaPZKoQ7b5/SyFpi3oBWXf2BQNy+r6iiBwg4AH4=");
paramMap.put("INDUSTRY_TYPE_ID" , "Retail");
**NOTE : Please keep in mind to send paytm server exact parameters plus one checksum.....**

Have you mention android:onClick="sign" in your signup.xml under layout directory? Please make sure it.

I think your code is corect.
add Log to sign function:
public void sign(View v) {
Log.e("tag","sign function called");
try {
// CALL validate method
validate();
} catch (Exception ex) {
String error = ex.getMessage();
}
}
if corect, you can show log is: "sign function called"

simply add this on your onCreate() method
signupbutton.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
Toast.makeText(getApplicationContext(),
"Button is clicked", 3000).show();
///what ever you want to do on signupbtn comes here
//add this try block if you need same functionality as `sign() method`
try {
// CALL validate method
validate();
} catch (Exception ex) {
String error = ex.getMessage();
}
}
});
and every time you cliecked signupbutton this method(Listener) will called.
Or
add this line in you xml file where you define the signupbutton
android:onClick="sign"
But the best way for me is to add clickListener as it makes it very clear from java class side that what is beaing called on clicking the button.

Rest with Android 4.0

Folks, I have an web service running on my PC, recently I changed my application from 2.2. for 4.0, and after that I cant connect to my WS anymore.
I'm looking for answers and found nothing.
My application refers the URL like thishttp://10.0.2.2:8080 ... But it dosn't work.
Heres my code:
private static final String URL_WS = "http://10.0.2.2:8080/WS_TaxiShare/)";
public String login(String email, String password) throws Exception {
String[] resposta = new WSClient().get(URL_WS + "login/login/?login="+ email +"&password="+ password);
String saida = resposta[1];
if (resposta[0].equals("200")) {
return saida;
} else {
return saida;
}
}
Now the WSClient
public class WSClient {
public final String[] get(String url) {
String[] result = new String[2];
HttpGet httpget = new HttpGet(url);
HttpResponse response;
try {
Log.i("Get taxi", "Url -> " + url);
response = HttpClientSingleton.getHttpClientInstace().execute(httpget);
HttpEntity entity = response.getEntity();
if (entity != null) {
result[0] = String.valueOf(response.getStatusLine().getStatusCode());
InputStream instream = entity.getContent();
result[1] = toString(instream);
instream.close();
Log.i("get", "Result from post JsonPost : " + result[0] + " : " + result[1]);
}
} catch (Exception e) {
Log.i("Exception no get WS taxi", "Exception ->" + e);
result[0] = "0";
result[1] = "Falha de rede!";
}
return result;
}

Well, i can solve my problem. Android 4.0 (I dont know when it begin), you cant call webservices on the main thread. And all you need to do is create a async method to do what you need in a separeated thread.
Here is my method
private class loginTask extends AsyncTask<String, Void, String> {
#Override
protected String doInBackground(String... urls) {
String response = "";
try {
WSTaxiShare ws = new WSTaxiShare();
response = ws.login(login, password);
} catch (Exception e) {
e.printStackTrace();
}
return response;
}
#Override
protected void onPostExecute(String strJson) {
}
and here is the call button
btnLogin.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
loginTask task = new loginTask();
task.execute(new String[] { "" });
}
});
}

Android animation only starts after AsyncTask completes

I am trying to create a native login screen, where the username and password boxes slide off the screen while the request is being processed (and slide back up if the login is unsuccessful).
In order to achieve that, I have defined my animation (DropDownAnimation) and I assign it to my LinearLayout (footer). When the user clicks the Login button, I start the animation, and then call a function (tryLogin()) which starts an AsyncTask. The AsyncTask handles all the work of creating and sending the login request, and getting the JSONObject response.
However, my problem is that the slideDown animation doesn't start until after the AsyncTask has completed. This doesn't look so bad on a successful login, but on a failed login it means that the LinearLayout never slides down - it jumps to the bottom of the screen, to begin the slideUp animation back to its original position.
This seems like a similar problem to this question, but I'm not doing using bindService() and all my non-UI code seems (to me) to be contained in the AsyncTask already. LogCat tells me:
06-24 04:37:35.141: I/Choreographer(5347): Skipped 137 frames! The application may be doing too much work on its main thread.
I assume those are the frames where the footer would be sliding down - but I can't figure out where it is that I'm executing things on the main thread. Here's my code for LoginPage and LoginTask.
LoginPage.java
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login_page);
login = (Button) findViewById(R.id.login);
username = (EditText) findViewById(R.id.username);
password = (EditText) findViewById(R.id.password);
footer = (LinearLayout) findViewById(R.id.footer);
// We must wait for the layout to be finalised before trying to find heights.
ViewTreeObserver vto = footer.getViewTreeObserver();
vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
initAnimations();
}
});
loading = (TextView) findViewById(R.id.loading);
login.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String mUsername = username.getText().toString();
String mPassword = password.getText().toString();
// Neither of these two things happen until after LoginTask is done.
footer.startAnimation(slideDown);
loading.setVisibility(TextView.VISIBLE);
tryLogin(mUsername, mPassword);
}
});
}
protected void tryLogin(String mUsername, String mPassword) {
Exception e;
String loginUrl = getString(R.string.login_url);
String clientId = getString(R.string.client_id);
String clientSecret = getString(R.string.client_secret);
LoginTask loginTask = (LoginTask) new LoginTask().execute(mUsername, mPassword, loginUrl, clientId, clientSecret);
if ((e = loginTask.getException()) != null) {
Toast.makeText(this, e.toString(), Toast.LENGTH_LONG).show();
Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();
} else {
JSONObject response;
try {
response = loginTask.get();
Log.d("login", response.toString());
if (!response.has("access_token")) {
loading.setVisibility(TextView.INVISIBLE);
footer.startAnimation(slideUp);
Toast.makeText(this, "Login error", Toast.LENGTH_LONG).show();
} else {
Intent i = new Intent(this, FullscreenWebView.class);
i.putExtra("accessToken", response.get("access_token").toString());
startActivity(i);
overridePendingTransition(0, 0);
}
} catch (InterruptedException e1) {
e1.printStackTrace();
Thread.currentThread().interrupt();
} catch (ExecutionException e1) {
e1.printStackTrace();
} catch (JSONException e1) {
e1.printStackTrace();
throw new RuntimeException(e);
}
}
}
LoginTask.java
class LoginTask extends AsyncTask<String, Void, JSONObject> {
private Exception exception;
#Override
protected JSONObject doInBackground(String... params) {
HttpURLConnection connection;
OutputStreamWriter request = null;
URL url = null;
JSONObject response = null;
String parameters = "grant_type=password&username="+params[0]+"&password="+params[1]+"&client_id="+params[3]+"&client_secret="+params[4];
try {
url = new URL(params[2]);
connection = (HttpURLConnection) url.openConnection();
connection.setDoOutput(true);
connection.setRequestProperty("Content-type", "application/x-www-form-urlencoded");
connection.setRequestMethod("POST");
request = new OutputStreamWriter(connection.getOutputStream());
request.write(parameters);
request.flush();
request.close();
// username or password is probably wrong
Log.d("login", ""+connection.getResponseCode());
if (connection.getResponseCode() != 200) {
return new JSONObject();
}
String line = "";
InputStreamReader isr = new InputStreamReader(connection.getInputStream());
BufferedReader reader = new BufferedReader(isr);
StringBuilder sb = new StringBuilder();
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
Log.d("login", sb.toString());
response = new JSONObject(sb.toString());
isr.close();
reader.close();
} catch (Exception e) {
this.exception = e;
}
return response;
}
}
I've also tried making LoginTask be a member class of LoginPage, and starting the animation in the onPreExecute() method, but that didn't change anything.
Any help is much appreciated!

When you use AsyncTask.get(), you are blocking the UI thread. As the animation runs on the UI thread, it appears as if it is not running (while in fact it is blocked by your long running tryLogin method).
Instead, you should move the code that relies on the result from the LoginTask to its onPostExecute method:
protected void tryLogin(String mUsername, String mPassword) {
String loginUrl = getString(R.string.login_url);
String clientId = getString(R.string.client_id);
String clientSecret = getString(R.string.client_secret);
new LoginTask().execute(mUsername, mPassword,
loginUrl, clientId, clientSecret);
}
LoginTask.java
class LoginTask extends AsyncTask<String, Void, JSONObject> {
private Exception exception;
#Override
protected JSONObject doInBackground(String... params) {
// Unchanged
}
public void onPostExecute(JSONObject response) {
if (exception != null) {
Toast.makeText(this, e.toString(), Toast.LENGTH_LONG).show();
Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();
} else {
Log.d("login", response.toString());
if (!response.has("access_token")) {
loading.setVisibility(TextView.INVISIBLE);
footer.startAnimation(slideUp);
Toast.makeText(this, "Login error", Toast.LENGTH_LONG).show();
} else {
Intent i = new Intent(this, FullscreenWebView.class);
i.putExtra("accessToken", response.get("access_token").toString());
startActivity(i);
overridePendingTransition(0, 0);
}
}
}
}

Asyntask not executing onPostExecute() - android

Your JSONObject does not contain a JSONString "email", so it is falling over at line String email = jsonObj.getString("email"); and going straight to catch block.
