Not able to get response from InputStreamReader in HttpUrlConnection in android

After execution for 5 to 6 times i am not able to get response and the message is also not going to gateway and the application get struck.At InputStreamReader i am not able to get any response after execution for 5 times.When i checked the logs no error is coming but the Input Stream is not printing.

HttpUrlConnection does not work on mobile device but on emulator

all of a sudden my mobile device can't connect to the local server anymore. async tasks are not executed and i just can't figure out why. slowly i'm getting really desperate because in my opinion i didn't change anything to cause this.
as an example, this is a background task which is not working

HttpClient is not supported any more in sdk 23. You have to use URLConnection or downgrade to sdk 22 (compile 'com.android.support:appcompat-v7:22.2.0')
If you need sdk 23, add this to your gradle:
android {
useLibrary 'org.apache.http.legacy'
}
HttpClient won't import in Android Studio

You should think about using a HTTP library, there is a bunch of them on internet, some are really easy to use, optimize and errorless.
For example, Volley (made by Google, I really like this one), okHttp or Picasso (for image).
You should take a look at this.

If you want to send (output), for example with POST or PUT requests you need to use this :-
urlConnection.setDoOutput(true);
In your code :-
public class Login extends AsyncTask<String, Void, String>{
private String loginUrl = "http://...";
private int loginSuccess = 0;
public String getToken(String fromJson) throws JSONException {
JSONObject json = new JSONObject(fromJson);
if(json.has("api_authtoken")) {
loginSuccess = 1;
String appToken = json.getString("api_authtoken");
return appToken;
}
else {
return json.toString();
}
}

clientprotocolexception DefaultHttpClient.execute()

I am using the following code to request a response from a webserver. The server sends a malformed response without headers which causes a ClientProtocolException. I have tried to use inspectors but they are not called before the exception is fired. I cannot change the server (it is within an embedded device, ALFA router R36).
Any suggestions to deal with this problem (btw: the code works perfect if the server response is well-formed)
Thanks in advance, Ton
class httpRequestTask extends AsyncTask <Integer, Integer, Integer> {
StringBuffer respTxt = new StringBuffer("");
int reqCode = 0;
protected Integer doInBackground(Integer... requestCode) {
Integer reqStatus = 0;
String url = "http://192.168.2.1/";
String authString = ("admin:admin");
switch( reqCode = requestCode[0].intValue()){
case Constants.HTTP_GET_STATUS_INFO: url += "/adm/status_info.asp"; break;
case Constants.HTTP_SCAN: url += "/goform/getUsbStaBSSIDListForm"; break;
}
try {
DefaultHttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet();
HttpResponse response;
request.setURI( new URI( url));
request.addHeader("Authorization", "Basic " + Base64.encodeToString(authString.getBytes(),Base64.NO_WRAP));
response = client.execute(request);
reqStatus = response.getStatusLine().getStatusCode();
String line;
BufferedReader in = new BufferedReader( new InputStreamReader(response.getEntity().getContent()));
while((line = in.readLine()) != null) respTxt.append(line);
} catch ( ClientProtocolException e){
Log.e("ALFA", "HTTPReq:ClientProtocolException " + e.toString());
} catch ( IOException e){
Log.e("ALFA", "HTTPReq:IOException " + e.toString());
} catch ( Exception e){
Log.e("ALFA", "HTTPReq:Exception " + e.toString());
}
return reqStatus;
}
protected void onPostExecute(Integer reqStatus) {
Intent intent = new Intent(Constants.HTTP_RESPONSE);
intent.putExtra( "reqCode", reqCode);
intent.putExtra( "reqStatus", reqStatus);
intent.putExtra( "rspTxt", respTxt.toString());
getBaseContext().sendBroadcast(intent);
}
}

Looking further to find a solution to the problem I found a suggestion to use a socket to request the server. I used Fiddler in combination with a browser on my PC to examine the data send to and received from the buggy server and read an article on Wikipedia, explaining the HTTP protocol. With that info and by using a Socket, I wrote a very basic httpRequestHandler than deals with the miss formed response from the buggy web server.
class httpSocketRequest extends AsyncTask<Integer, Integer, Integer> {
StringBuffer respTxt = new StringBuffer("");
int reqCode = 0;
int reqStatus = 0;
protected Integer doInBackground(Integer... requestCode) {
String ip = "192.168.2.1";
String path = "";
String authString = ("admin:admin");
Socket socket = null;
switch( reqCode = requestCode[0].intValue()){
case Constants.HTTP_GET_STATUS_INFO: path = "adm/status_info.asp"; break;
case Constants.HTTP_SCAN: path = "goform/getUsbStaBSSIDListForm"; break;
}
try {
socket = new Socket( ip, 80);
PrintWriter out = new PrintWriter( socket.getOutputStream());
out.println( "GET http://" + ip + "/" + path + " HTTP/1.0");
out.println( "Authorization: Basic " + Base64.encodeToString(authString.getBytes(),Base64.NO_WRAP));
out.println( "");
out.flush();
BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
String line;
int lineCnt = 0;
while((line = in.readLine()) != null){
if( lineCnt >= 0){
lineCnt++;
if(lineCnt == 1){ // first line should start with "HTTP/1.x " followed by a 3 digit status
if( line.length() > 12 && line.substring(0, 6).equals("HTTP/1")){
int p = line.indexOf(" ");
reqStatus = Integer.parseInt(line.substring(p+1, p+4));
continue;
} else { // not a well formed response
lineCnt = -1; // just put everything into respTxt
reqStatus = 200; // and assume everything went OK
}
} else if( lineCnt > 1){ // process rest of headers
if( line.length() == 0){
lineCnt = -1; // done with headers
} else {
// TODO insert code to process other headers
}
continue;
}
}
respTxt.append(line + "\n");
}
} catch (Exception e) {
Log.e("ALFA", "HTTPReq:Exception " + e.toString());
} finally {
try {
if( socket != null) socket.close();
} catch (IOException e) {
Log.e("ALFA", "HTTPReq:Exception closing socket" + e.toString());
}
}
return reqStatus;
}
protected void onPostExecute(Integer reqStatus) {
Intent intent = new Intent(Constants.HTTP_RESPONSE);
intent.putExtra( "reqCode", reqCode);
intent.putExtra( "reqStatus", reqStatus);
intent.putExtra( "rspTxt", respTxt.toString());
getBaseContext().sendBroadcast(intent);

HTTP GET on Android

I have a method to insert data into server like this:
public void doInsert(){
try {
// setiap parameter yang akan dikirim melalui http
// harus encode agar
// dapat terbaca dengan baik oleh server
String no_imei = URLEncoder.encode(noImei.getText().toString(), "utf-8");
String nik = URLEncoder.encode(user.getText().toString(), "utf-8");
String pass = URLEncoder.encode(password.getText().toString(), "utf-8");
url += "?no_imei=" + no_imei + "&&nik=" + nik + "&&password=" + pass;
getRequest(url);
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Another method that I have:
public void getRequest(String Url) {
HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet(url);
try {
HttpResponse response = client.execute(request);
Toast.makeText(this, "Tambah Data " + request(response) + " ",Toast.LENGTH_SHORT).show();
} catch (Exception ex) {
//Toast.makeText(this, "Tambah Data Gagal !", Toast.LENGTH_SHORT).show();
}
}
And like this:
public static String request(HttpResponse response) {
String result = "";
try {
InputStream in = response.getEntity().getContent();
BufferedReader reader = new BufferedReader(
new InputStreamReader(in));
StringBuilder str = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
str.append(line + "\n");
}
in.close();
result = str.toString();
} catch (Exception ex) {
result = "Error";
}
return result;
}
onClick method:
private View.OnClickListener onSave=new View.OnClickListener()
{
public void onClick(View v)
{
//Dbhelper helper = new Dbhelper(UserForm.this);
Cursor c = helper.Login(almagId);
if (noImei.getText().toString().equals("")||
user.getText().toString().equals("")||
password.getText().toString().equals("")
) {
Toast.makeText(UserForm.this, "Data Harus di isi", Toast.LENGTH_LONG).show();
}else if(c.moveToFirst()){
if(noImei.getText().equals(c.getString(0))||
user.getText().equals(c.getString(1))){
Toast.makeText(UserForm.this, "Data Sudah ada", Toast.LENGTH_LONG).show();
helper.close();
}
}else
{
doInsert();
helper.insertUser(noImei.getText().toString(),user.getText().toString(),password.getText().toString());
//Toast.makeText(UserForm.this, "Data Berhasil disimpan", Toast.LENGTH_LONG).show();
}
startActivity(new Intent(UserForm.this,MenuUtama.class));
user.setText("");
password.setText("");
return;
}
};
In the onClick method when response from server SUCCESS I want to do some activity. How can I do that? I tried with condition if my activity not running.

You should probably go with
if (response != null && response.getStatusLine().getStatusCode() == 200) { }

You have to add your activity in AndroidManifest.xml. Refer this link : Using Intent in an Android application to show another activity

looks like login in your if statement is little off.
if(request(response).equals("SUCCESS")){ startActivityForResult(new Intent(this,MainMenu.class))}
first, this does not make sense
if(request(response).equals("SUCCESS"))
what are you trying to do, cast request into response???
second:
.equals("SUCCESS"))
response is not an String object, are you looking for status code??
read over Android's HttpResponse
http://developer.android.com/reference/org/apache/http/HttpResponse.html
Example Code
if (response != null && response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
//Do Something
}
