Android Http to Https and SSL crt

I am working on https post request.
I did successfully http post request but i don't know how to change it with https SSL crt.
How can I add SSL crt in project and how to convert http to https.
I tried many examples but i didn't get it.
My http post request code is.. saVersion is my lib
public class ServerCommunication implements Runnable, IServerCommunication {
private static final String TAG = ServerCommunication.class.getSimpleName();
private String url;
private String userAgent;
private byte[] data;

}
public void run()
{

if(url.equals(""))
{
Log.e(TAG, "URL is an empty string... aborting sending procedure");
return;
}
// make URL
HttpPost httpost = new HttpPost(url);
StringEntity se;
try {
se = new StringEntity(new String(data) + "\r\n");
httpost.setEntity(se);
httpost.setHeader("Accept", "application/json");

// Get User Agent String
httpost.setHeader("User-Agent", userAgent); // set string
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
HttpResponse response = httpclient.execute(httpost);
InputStreamReader sr = new InputStreamReader(response.getEntity().getContent());
byte[] respContent = IOUtils.toByteArray(sr);
receiveBytestream(respContent);
}
catch (ClientProtocolException e)

I faced this same issue before some days, I have published into my blog. Refer it. Hope it helps you regarding same.

How to get facebook profile picture of user in facebook SDK Android

I used facebook 3.6 sdk . i want to get profile picture from graph user , last time i got image but now it returns null Bitmap.
I used following code
private void onSessionStateChange(Session session, SessionState state,
Exception exception) {
if (session.isOpened()) {
Request.newMeRequest(session, new Request.GraphUserCallback() {
#Override
public void onCompleted(GraphUser user, Response response) {
if (user != null) {
try {
URL imgUrl = new URL("http://graph.facebook.com/"
+ user.getId() + "/picture?type=large");
InputStream in = (InputStream) imgUrl.getContent();
Bitmap bitmap = BitmapFactory.decodeStream(in);
//Bitmap bitmap = BitmapFactory.decodeStream(imgUrl // tried this also
//.openConnection().getInputStream());
} catch (Exception e) {
e.printStackTrace();
}
}
}
}).executeAsync();
}
}
When i use direct link then it works.
imgUrl = new URL("https://fbcdn-dragon-a.akamaihd.net/hphotos-ak-ash3/t39.2365-6/851558_160351450817973_1678868765_n.png");
i refered this also Graph API Reference

Auto redirection works automatically when original and redirected protocols are same.
So, try to load images from https instead of http : "https://graph.facebook.com/USER_ID/picture"; since image's url is "https://fbcdn-profile-a.akamaihd.net/...."
Then BitmapFactory.decodeStream shall work again.

Try this code,
try {
URL image_value = new URL("http://graph.facebook.com/"+ user.getId()+ "/picture?type=large");
Bitmap bmp = null;
try {
bmp = BitmapFactory.decodeStream(image_value.openConnection().getInputStream());
} catch (IOException e) {
e.printStackTrace();
}
profile_pic.setImageBitmap(bmp);
} catch (MalformedURLException e) {
e.printStackTrace();
}
here profile_pic is your ImageView replace it with your ImageView Name.
Edit
Session.openActiveSession(this, true, new Session.StatusCallback() {
#Override
public void call(Session session, SessionState state,
Exception exception) {
if (session.isOpened()) {
// make request to the /me API
Request.executeMeRequestAsync(session,
new Request.GraphUserCallback() {
#Override
public void onCompleted(GraphUser user,
Response response) {
if (user != null) {
try {
URL image_value = new URL("http://graph.facebook.com/"+ user.getId()+ "/picture?type=large");
Bitmap bmp = null;
try {
bmp = BitmapFactory.decodeStream(image_value.openConnection().getInputStream());
} catch (IOException e) {
e.printStackTrace();
}
profile_pic.setImageBitmap(bmp);
} catch (MalformedURLException e) {
e.printStackTrace();
}
}
}
});
} else {
Toast.makeText(getApplicationContext(), "Error...",
Toast.LENGTH_LONG);
}
}
});

Try this code
public static String getProfilePicture() {
String stringURL = null;
try {
stringURL = "http://graph.facebook.com/" + URLEncoder.encode(DataStorage.getFB_USER_ID(), "UTF-8") + "?fields=" + URLEncoder.encode("picture", "UTF-8");
} catch (UnsupportedEncodingException e1) {
e1.printStackTrace();
}
LogUtil.log(TAG, "getProfilePicture final url is : "+stringURL);
JSONObject jsonObject = null;
String response = "";
try {
HttpGet get = new HttpGet(stringURL);
get.setHeader("Content-Type", "text/plain; charset=utf-8");
get.setHeader("Expect", "100-continue");
HttpResponse resp = null;
try {
DefaultHttpClient httpClient = new DefaultHttpClient();
resp = httpClient.execute(get);
} catch (Exception e) {
e.printStackTrace();
}
// get the response from the server and store it in result
DataInputStream dataIn = null;
try {
// dataIn = new DataInputStream(connection.getInputStream());
if (resp != null) {
dataIn = new DataInputStream((resp.getEntity().getContent()));
}
}catch (Exception e) {
e.printStackTrace();
}
if(dataIn != null){
String inputLine;
while ((inputLine = dataIn.readLine()) != null) {
response += inputLine;
}
if(Constant.DEBUG) Log.d(TAG,"final response is : "+response);
if(response != null && !(response.trim().equals(""))) {
jsonObject = new JSONObject(response);
}
dataIn.close();
}
} catch (Exception e) {
e.printStackTrace();
}
String profilePicture = "";
try{
if(jsonObject != null){
JSONObject jsonPicture = jsonObject.getJSONObject("picture");
if(jsonPicture != null){
JSONObject jsonData = jsonPicture.getJSONObject("data");
if(jsonData != null){
profilePicture = jsonData.getString("url");
}
}
}
}catch (Exception e) {
e.printStackTrace();
}
LogUtil.log(TAG, "user fb profile picture url is : "+profilePicture);
return profilePicture;
}

I tried to use redirect page "https://fbcdn-profile-a.akamaihd.net/" + USERID + "/picture?type=large" but it didn't work.
It seems that now facebook redirect you to a different page that we cannot guess. Kind of random variables in URL.
So try below method to get the new redirect page provided by facebook.
private String getProfileGif(String userId) throws IOException {
HttpParams httpParams = new BasicHttpParams();
httpParams.setParameter("http.protocol.handle-redirects", false);
HttpGet pageToRequest = new HttpGet("http://graph.facebook.com/" + userId + "/picture?type=large");
pageToRequest.setParams(httpParams);
AndroidHttpClient httpClient = AndroidHttpClient
.newInstance("Android");
HttpMessage httpResponse = httpClient.execute(pageToRequest);
Header header = httpResponse.getFirstHeader("location");
if(header != null){
return(header.getValue());
}
return "";
}
This is gonna return you the real gif URL (final URL).
After that, use this new URL to parse your bitmap.
Change from:
URL image_value = new URL("http://graph.facebook.com/"+ user.getId()+ "/picture?type=large");
to
URL image_value = new URL(getProfileGif(user.getId());
Bitmap bmp = BitmapFactory.decodeStream(image_value.openConnection().getInputStream());
PS: Dont execute getProfileGif or any URL request in main thread.
Let me know your results.

In background check the Play Store to determine if an app is available to download on the device

I know I can link to the Play Store with the URL:
market://details?id=com.example.appname
What I would love to do is 'ping' this URL in the background, and determine if the app is actually available, then, I can modify my UI as appropriate.

Let's assume that, if app is unavailable, the page under http://play.google.com/store/apps/details?id=<package_name> contains, for example, word error-section. If app is available, it does not contain this word.
Make HTTP GET to that URL and search for error-section.
No error-section - your app is available.
Otherwise, it's unavailable.
Like this:
final HttpClient client = new DefaultHttpClient();
final String getURL = "http://play.google.com/store/apps/details?id=<package_name>";
final HttpGet get = new HttpGet(getURL);
final HttpResponse responseGet = client.execute(get);
final HttpEntity resEntityGet = responseGet.getEntity();
if (resEntityGet != null)
{
final String response = EntityUtils.toString(resEntityGet);
if (response.indexOf("error-section") == -1)
{
// available
}
else
{
// unavailable
}
}

private class URLTest extends AsyncTask<Void, Void, Void> {
#Override
protected Void doInBackground(Void... params) {
try {
try {
HttpClient httpclient = new DefaultHttpClient();
String strurl = "https://play.google.com/store/apps/details?id=com.rovio.angrybirdsstarwars.ads.iap";
// String strurl =
// "https://play.google.com/store/apps/details?id=com.rovio.angrybirdsstarwars.ads.iaptest";
// //fake packagename append with "test"
HttpGet httpget = new HttpGet(strurl);
HttpResponse httpresp = httpclient.execute(httpget);
if (httpresp.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
Log.e("Found", "YES");
} else if (httpresp.getStatusLine().getStatusCode() == HttpStatus.SC_NOT_FOUND) {
Log.e("Found", "NO");
}
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} catch (Exception e) {
Log.e("", "");
}
return null;
}
}
i tried with correct & fake packages and its giving bad request responze if the app not available & positive(success 200 code) if app is there..so plz check it once it might help u.

Http delete gets bad request in Android

I am working with Android http stuff to register/unregister to the server. I have a DELETE request to use HttpDelete. I am getting Http401 'Bad request' error when I try to call it. I cannot why it is happening. Please help me.
Here is my code:
HttpUtils.java
private BasicHttpParams mParams;
private UsernamePasswordCredentials mCredentials = null;
private ResponseHandler mResponseHandler = null;
public void setUserCredentials(String userName, String password) {
this.mCredentials = new UsernamePasswordCredentials(userName, password);
}
public void setResponseHandler(ResponseHandler responseHandler){
this.mResponseHandler = responseHandler;
}
public Result<String> delete(String url){
Result<String> result = new Result<T>();
result.setStatus(Result.FAIL);
try {
DefaultHttpClient httpClient = new DefaultHttpClient(mParams);
httpClient.setParams(mParams);
httpClient.getCredentialsProvider().setCredentials(new AuthScope(null, -1), mCredentials);
HttpResponse response = httpClient.execute(new HttpDelete(url));
result.setResult(mResponseHandler.handleResponse(response));
result.setStatus(Result.SUCCESS);
} catch (IllegalArgumentException e) {
e.printStackTrace();
result.setMessage(e.getMessage());
} catch (ClientProtocolException e) {
e.printStackTrace();
result.setMessage(e.getMessage());
} catch (ConnectTimeoutException e) {
result.setMessage("Connection timed out.");
} catch (IOException e) {
e.printStackTrace();
result.setMessage(e.getMessage());
}
return result;
}
UnregisterTask.java
#Override
protected Void doInBackground(String... urls) {
if (urls==null || urls.length!=1)
return null;
String url = urls[0];
HttpUtils httpUtils = new HttpUtils();
httpUtils.setUserCredentials("userid", "password");
httpUtils.setResponseHandler(new UnrgisterHandler());
httpUtils.delete(url);
Result<String> result = aClient.delete(url);
if (result!=null || result.result != null){
//Do Something
}
}
//UnrgisterActivity.java
public void onUnregisterButtonClick(View view){
UnregisterTask task = new UnregisterTask(this);
task.execute(ServerConfig.getIdmServer() + ServerConfig.DELETE_DEVICE + "myid");
}
Error recevied:
Apache Tomcat/7.0.26 - Error report HTTP Status 400 - type Status reportmessage description The request sent by the client was syntactically incorrect ().Apache Tomcat/7.0.26
Thanks in Advance.

I fixed it by myself but I do not understand clearly why the error happened. I changed my code after searching how to set basic authentication.
public Result<T> delete(String url)
Result<T> result = new Result<T>();
result.setStatus(Status.FAIL);
try {
DefaultHttpClient http = new DefaultHttpClient();
if (this.mCredentials!=null){
CredentialsProvider credProvider = new BasicCredentialsProvider();
credProvider.setCredentials(new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT), this.mCredentials);
http.setCredentialsProvider(credProvider);
}
HttpDelete delete = new HttpDelete(url);
//delete.setEntity(new StringEntity(data, "UTF8"));
delete.addHeader("Content-type", JSON_TYPE);
HttpResponse response = http.execute(delete);
result.setResult(mResponseHandler.handleResponse(response));
result.setStatus(Result.Status.SUCCESS);
} catch (IllegalArgumentException e) {
e.printStackTrace();
result.setMessage(e.getMessage());
} catch (ClientProtocolException e) {
e.printStackTrace();
result.setMessage(e.getMessage());
} catch (ConnectTimeoutException e) {
result.setMessage("Connection timed out.");
} catch (IOException e) {
e.printStackTrace();
result.setMessage(e.getMessage());
}
return result;
}
A bit still confusing. Anyway, now it works charm.

I need know how much bytes has been uploaded for update a progress bar android

I am developing an app for upload video to a Apache/PHP Server. In this moment I already can upload videos. I need show a progress bar while the file is being uploaded. I have the next code using AsyncTask and HTTP 4.1.1 Libraries for emulate the FORM.
class uploadVideo extends AsyncTask<Void,Void,String>{
#Override
protected String doInBackground(Void... params) {
// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.youtouch.cl/videoloader/index.php");
try {
// Add your data
File input=new File(fileName);
MultipartEntity multi=new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
multi.addPart("video", new FileBody(input));
httppost.setEntity(multi);
// Execute HTTP Post Request
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
BufferedReader reader = new BufferedReader(
new InputStreamReader(
entity.getContent(), "UTF-8"));
String sResponse = reader.readLine();
return sResponse;
} catch (ClientProtocolException e) {
Log.v("Uri Galeria", e.toString());
e.printStackTrace();
} catch (IOException e) {
Log.v("Uri Galeria", e.toString());
e.printStackTrace();
}
return "error";
}
#Override
protected void onProgressUpdate(Void... unsued) {
//Here I do should update the progress bar
}
#Override
protected void onPostExecute(String sResponse) {
try {
if (pd.isShowing())
pd.dismiss();
if (sResponse != null) {
JSONObject JResponse = new JSONObject(sResponse);
int success = JResponse.getInt("SUCCESS");
String message = JResponse.getString("MESSAGE");
if (success == 0) {
Toast.makeText(getApplicationContext(), message,
Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getApplicationContext(),
"Video uploaded successfully",
Toast.LENGTH_SHORT).show();
}
}
} catch (Exception e) {
Toast.makeText(getApplicationContext(),
e.getMessage(),
Toast.LENGTH_LONG).show();
Log.e(e.getClass().getName(), e.getMessage(), e);
}
}
I need know where I can get how much bytes has been uploaded. File.length is the total size.

Have you tried extending FileBody? Presumably the POST will either call getInputStream() or writeTo() in order to actually send the file data to the server. You could extend either of these (including the InputStream returned by getInputStream()) and keep track of how much data has been sent.

thank to cyngus's idea I have resolved this issue. I have added the next code for tracking the uploaded bytes:
Listener on upload button:
btnSubir.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//pd = ProgressDialog.show(VideoAndroidActivity.this, "", "Subiendo Video", true, false);
pd = new ProgressDialog(VideoAndroidActivity.this);
pd.setMessage("Uploading Video");
pd.setIndeterminate(false);
pd.setMax(100);
pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
pd.show();
//Thread thread=new Thread(new threadUploadVideo());
//thread.start();
new UploadVideo().execute();
}
});
Asynctask for run the upload:
class UploadVideo extends AsyncTask<Void,Integer,String> {
private FileBody fb;
#Override
protected String doInBackground(Void... params) {
// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.youtouch.cl/videoloader/index.php");
int count;
try {
// Add your data
File input=new File(fileName);
// I created a Filebody Object
fb=new FileBody(input);
MultipartEntity multi=new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
multi.addPart("video",fb);
httppost.setEntity(multi);
// Execute HTTP Post Request
HttpResponse response = httpclient.execute(httppost);
//get the InputStream
InputStream is=fb.getInputStream();
//create a buffer
byte data[] = new byte[1024];//1024
//this var updates the progress bar
long total=0;
while((count=is.read(data))!=-1){
total+=count;
publishProgress((int)(total*100/input.length()));
}
is.close();
HttpEntity entity = response.getEntity();
BufferedReader reader = new BufferedReader(
new InputStreamReader(
entity.getContent(), "UTF-8"));
String sResponse = reader.readLine();
return sResponse;
} catch (ClientProtocolException e) {
Log.v("Uri Galeria", e.toString());
e.printStackTrace();
} catch (IOException e) {
Log.v("Uri Galeria", e.toString());
e.printStackTrace();
}
return "error";
}
#Override
protected void onProgressUpdate(Integer... unsued) {
pd.setProgress(unsued[0]);
}
#Override
protected void onPostExecute(String sResponse) {
try {
if (pd.isShowing())
pd.dismiss();
if (sResponse != null) {
Toast.makeText(getApplicationContext(),sResponse,Toast.LENGTH_SHORT).show();
Log.i("Splash", sResponse);
}
} catch (Exception e) {
Toast.makeText(getApplicationContext(),
e.getMessage(),
Toast.LENGTH_LONG).show();
Log.e(e.getClass().getName(), e.getMessage(), e);
}
}
}
The progress bar load is bit slow (in starting seems be freeze and then load of 1 to 100 very fast), but works.
Sorry, my english is regular :(.

Check my answer here, I guess it answers your question:
But update the file path of the image to your to be uploaded video
https://stackoverflow.com/questions/15572747/progressbar-in-asynctask-is-not-showing-on-upload

What I used to do is to extends org.apache.http.entity.ByteArrayEntity and override the writeTo function like below, while bytes output it will pass though writeTo(), so you can count current output bytes:
#Override
public void writeTo(final OutputStream outstream) throws IOException
{
if (outstream == null) {
throw new IllegalArgumentException("Output stream may not be null");
}
InputStream instream = new ByteArrayInputStream(this.content);
try {
byte[] tmp = new byte[512];
int total = (int) this.content.length;
int progress = 0;
int increment = 0;
int l;
int percent;
// read file and write to http output stream
while ((l = instream.read(tmp)) != -1) {
// check progress
progress = progress + l;
percent = Math.round(((float) progress / (float) total) * 100);
// if percent exceeds increment update status notification
// and adjust increment
if (percent > increment) {
increment += 10;
// update percentage here !!
}
// write to output stream
outstream.write(tmp, 0, l);
}
// flush output stream
outstream.flush();
} finally {
// close input stream
instream.close();
}
}
