I've been using in my app HttpResponseCache successfully, but when my phone updated to Lollipop I realized that HttpResponseCache now never get "hit", always do the network request. I've confirmed that in Android versions pre Lollipop are still working well.
Maybe it's something that I did wrong and with new Android changes it has been appeared.
Has anyone any idea?
My code:
Application class, onCreate...
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
try {
File httpCacheDir = new File(getApplicationContext().getCacheDir()
, "http");
long httpCacheSize = 10 * 1024 * 1024;
HttpResponseCache.install(httpCacheDir, httpCacheSize);
} catch (IOException e) {
Log.i(TAG, "HTTP response cache installation failed:" + e);
}
} else {
try {
File httpCacheDir = new File(getCacheDir(), "http");
long httpCacheSize = 10 * 1024 * 1024;
Class.forName("android.net.http.HttpResponseCache")
.getMethod("install", File.class, long.class)
.invoke(null, httpCacheDir, httpCacheSize);
} catch (Exception e) {
Log.i(TAG, "HTTP response cache installation failed:" +
}
}
Function to manage request
public static InputStream fetchInputStream(String strURL, boolean forceRefresh)
throws IOException {
HttpURLConnection mHttpConn = null;
InputStream inputStream = null;
URL url = new URL(strURL);
HttpResponseCache cache;
try {
mHttpConn = (HttpURLConnection) url.openConnection();
if (forceRefresh) {
mHttpConn.addRequestProperty("Cache-Control", "no-cache");
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
cache = HttpResponseCache.getInstalled();
if (cache != null) {
Log.i("TEST CACHE", "TEST PETICION: Req count: "
+ cache.getRequestCount() + ", hit count "
+ cache.getHitCount() + ", netWork count "
+ cache.getNetworkCount() + " size = "
+ cache.size() + " <-----------------");
}
}
mHttpConn.setUseCaches(true);
mHttpConn.setDefaultUseCaches(true);
mHttpConn.setRequestMethod("GET");
mHttpConn.setConnectTimeout(30000);
mHttpConn.setReadTimeout(30000);
mHttpConn.connect();
if (mHttpConn.getResponseCode() == HttpURLConnection.HTTP_OK) {
inputStream = mHttpConn.getInputStream();
}
} catch (IOException ex) {
Log.e("NetworkConnectionManager InputStream", "Exception opening ["
+ strURL + "] ->", ex);
mHttpConn.disconnect();
throw ex;
}
return inputStream;
}
After every request
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
HttpResponseCache cache = HttpResponseCache.getInstalled();
if (cache != null) {
cache.flush();
}
}
Example request header:
Cache-Control → max-age=300
Connection → keep-alive
Content-Encoding → gzip
Content-Type → application/json; charset=utf-8
Date → Wed, 08 Apr 2015 12:37:35 GMT
Expires → Wed, 08 Apr 2015 12:42:35 GMT
Last-Modified → Wed, 08 Apr 2015 12:37:35 GMT
Server → nginx
Transfer-Encoding → chunked
Vary → Accept-Encoding
X-Cached → MISS
After having this problem for days I ran into this issue. It is fixed again in Marshmallow.
It is a bug in lollipop where the Vary - > Accept-Encoding header breaks the cache because Accept-Encoding gets filled in by default but not written away.
Here is a link to the issue:
https://code.google.com/p/android/issues/detail?id=162475
The fix is to set the Accept-Encoding explicitly:
Accept-Encoding -> gzip
or
Accept-Encoding -> identity
On the reading side you have to add this to the reading of the input stream:
String encoding = urlConnection.getHeaderField("Content-Encoding");
boolean gzipped = encoding!=null && encoding.toLowerCase().contains("gzip");
Inputstream inputStream;
if(gzipped)
inputStream = new GZIPInputStream(urlConnection.getInputStream());
else
inputstream = urlConnection.getInputStream();
I've had similar problem. I was expecting images to be cached but they weren't.
What turned out to be the problem was that I was not closing InputStream after it being read into a Bitmap.
Your fetchInputStream returns an InputStream that it got from http connection, make sure you close it properly.
The android http cache will not save a resource until you close the connection's InputStream.

I am trying to login to my TLS1.2 server on an old Android device running Jellybean 4.1.2, with the BouncyCastle (SpongyCastle) library, but it doesn't work. That version of Android does not have TLS enabled by default, so I needed the 3rd party lib to use it.
There are two problems.
1. I get a HTTP 302 instead of a JSON response.
2. I don't know how to send a JSON payload (for other endpoints I'll be using
With the HTTP 302, I get the following response:
Result: HTTP/1.1 302 Found
Server: Apache-Coyote/1.1
Cache-Control: private
Expires: Thu, 01 Jan 1970 00:00:00 UTC
Set-Cookie: JSESSIONID=83C535625CDEF9DEC3D7890F1A9C86B0; Path=/; Secure; HttpOnly
Location: https://www.google.com/login/auth Content-Length: 0
Date: Wed, 14 Mar 2018 15:32:19 GMT
Via: 1.1 google
Set-Cookie: GCLB=CMfzgbfeh7bLpwE; path=/; HttpOnly
Alt-Svc: clear
Connection: close
So it seems its trying to redirect to some sort of Google login, which is weird.
Also, with number 2 above, where I'm trying to send a payload, do I just add another output.write(myJSONPayload); or do I have to do something else?
My code is as follows:
{
java.security.SecureRandom secureRandom = new java.security.SecureRandom();
Socket socket = new Socket("www.myserver.com", 443);
TlsClientProtocol protocol = new TlsClientProtocol(socket.getInputStream(), socket.getOutputStream(), secureRandom);
DefaultTlsClient client = new DefaultTlsClient() {
public TlsAuthentication getAuthentication() throws IOException {
TlsAuthentication auth = new TlsAuthentication() {
// Capture the server certificate information!
public void notifyServerCertificate(Certificate serverCertificate) throws IOException {
}
public TlsCredentials getClientCredentials(CertificateRequest certificateRequest) throws IOException {
return null;
}
};
return auth;
}
};
protocol.connect(client);
java.io.OutputStream output = protocol.getOutputStream();
output.write("GET / HTTP/1.1\r\n".getBytes("UTF-8"));
//Get auth with my own class to generate base 64 encoding
output.write(("Authorization: " + BasicAuthentication.getAuthenticationHeader("myuser", "mypass")).getBytes());
output.write("Host: www.myserver.com/logon\r\n".getBytes("UTF-8"));
output.write("Connection: close\r\n".getBytes("UTF-8")); // So the server will close socket immediately.
output.write("\r\n".getBytes("UTF-8")); // HTTP1.1 requirement: last line must be empty line.
output.flush();
java.io.InputStream input = protocol.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(input));
String line;
StringBuilder sb = new StringBuilder();
try {
while ((line = reader.readLine()) != null) {
Log.d(TAG, "--> " + line);
sb.append(line).append("\n");
}
} catch (TlsNoCloseNotifyException e) {
Log.d(TAG, "End of stream");
}
String result = sb.toString();
Log.d(TAG, "Result: " + result);
}
Another question, do I have the correct HOST specified? Am I right to have the base URL in the Socket, and the full URL in the OutputStream?
The solution here was to add this method to my custom SSLSocketFactory:
private static void setupSecurityForTLS() {
if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.KITKAT) {
Log.d(TAG, "Adding new security provider");
Security.insertProviderAt(new BouncyCastleJsseProvider(), 1);
Security.insertProviderAt(new BouncyCastleProvider(), 2);
}
}
and call it BEFORE I initialise the socket.
You can also add the 2 lines to a static initialiser at the top of the class, eg:
static {
Security.insertProviderAt(new BouncyCastleJsseProvider(), 1);
Security.insertProviderAt(new BouncyCastleProvider(), 2);
}
I'm working on a application in Android which has a heavy load of web service requests.
I already have a LoginActivity in which the user introduces the username and the password and the server responses with the result and a token. Then, several activities (all of them extend from a common BaseActivity) do the heavy requests.
I have also a ServiceManager class which is responsible for all the service requests and HTTP petitions.
I'm working on implementing the HttpResponseCache to relieve this net load. Right now I have the following code:
In my LoginActivity's (the first being launched) onCreate:
//HTTP cache
try {
File httpCacheDir = new File(this.getCacheDir(), "http");
long httpCacheSize = 10 * 1024 * 1024; //10 MiB
HttpResponseCache.install(httpCacheDir, httpCacheSize);
Log.d(TAG, "Cache installed");
} catch (IOException e) {
Log.i(TAG, "HTTP response cache installation failed:" + e);
}
In my ServiceManager's httpRequest function, which is the one actually being executed every time I try to make an HTTP request:
//HTTPS connection
URL requestedUrl = new URL(uri);
httpsConnection = (HttpURLConnection) requestedUrl.openConnection();
httpsConnection.setUseCaches(true);
httpsConnection.setDefaultUseCaches(true);
httpsConnection.setRequestMethod("GET");
BufferedReader br = new BufferedReader(
new InputStreamReader(httpsConnection.getInputStream()));
String line;
while ((line = br.readLine()) != null) {
httpResponse += line;
}
br.close();
httpsConnection.disconnect();
HttpResponseCache cache = HttpResponseCache.getInstalled();
Log.d(TAG, "Cache: " + cache);
if (cache != null) {
Log.d(TAG, "Net count: " + cache.getNetworkCount());
Log.d(TAG, "Hit count: " + cache.getHitCount());
Log.d(TAG, "Request count: " + cache.getRequestCount());
cache.flush();
}
try{
URI uriCached = new URI("<myurl>");
CacheResponse cr = cache.get(uriCached, "GET", null);
String line;
BufferedReader br = new BufferedReader(new InputStreamReader(cr.getBody()));
while ((line = br.readLine()) != null) {
Log.d(TAG, line);
}
} catch (URISyntaxException e1) {
e1.printStackTrace();
} catch (IOException e2) {
e2.printStackTrace();
}
Right now, since the server side is not ready, the URL I'm doing the requests to is always the same.
As you can see, I'm debugging a few things, these are the results:
Cache installed
Cache: android.net.http.HttpResponseCache#b3e3b6
Net count: X
Hit count: 0
Request count: X
{myJson}
As you can see, the cache is able to read my JSON when I get it via the cache.get() method, but it's never hitting.
My server side directive Cache-Control in the header of the response is:
Cache-Control:public
Cache-Control:max-age=3800
Why is the cache never hitting?
Thank you very much!
I found the problem.
I was trying to cache petitions to a PHP that returns JSON. PHP is always considered as dynamic content (and it actually is), and it's never cached.
The path to follow when trying to cache JSON y application-side only and not server-side. This way, it won't event make a request.
Best.
EDIT
Best solution for this kind of trouble is, undoubtedly, to use Volley
I have an API on rails 4 that accepts HTTP requests in the form of a file upload. Everything works fine on Localhost but on Heroku the POST request doesn't seem to do anything.
This is what my Android POST request looks like:
public static byte[] postData(String operation, byte[] binaryData) {
String urlString = baseUrl + "/" + operation;
String boundary = "uahbkjqtjgecuaoehuaebkjahj";
byte[] postData = null;
URLConnection urlConnection;
DataInputStream responseDataInputStream;
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
StringBuffer startBuffer = new StringBuffer("--").append(boundary).append("\r\n");
startBuffer.append("Content-Disposition: form-data; name=\"data\"; ").append("filename=\"data.dat\"\r\n");
startBuffer.append("Content-Type: application/octet-stream\r\n\r\n");
StringBuffer endBuffer = new StringBuffer("\r\n--").append(boundary).append("--\r\n");
String startRequestData = startBuffer.toString();
String endRequestData = endBuffer.toString();
try {
URL url = new URL(urlString);
urlConnection = url.openConnection();
urlConnection.setDoInput(true);
urlConnection.setDoOutput(true);
urlConnection.setUseCaches(false);
urlConnection.setConnectTimeout(5000); //5 seconds
urlConnection.setReadTimeout(5000);//5 seconds
urlConnection.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary);
urlConnection.connect();
DataOutputStream _request = new DataOutputStream(urlConnection.getOutputStream());
// Write the start portion of the request
byteArrayOutputStream.write(startRequestData.getBytes());
postData = byteArrayOutputStream.toByteArray();
_request.write(postData);
// Write the Binary Packet
_request.write(binaryData);
// Write the end portion of the request
byteArrayOutputStream.reset();
byteArrayOutputStream.write(endRequestData.getBytes());
postData = byteArrayOutputStream.toByteArray();
_request.write(postData);
_request.flush();
_request.close();
// Read in the response bytes
InputStream is = urlConnection.getInputStream();
responseDataInputStream = new DataInputStream(is);
byteArrayOutputStream.reset();
byte[] buffer = new byte[responseDataInputStream.available()];
while (responseDataInputStream.read(buffer) != -1) {
byteArrayOutputStream.write(buffer);
buffer = new byte[responseDataInputStream.available()];
}
byte[] responseData = byteArrayOutputStream.toByteArray();
return responseData;
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (SocketTimeoutException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
return new byte[0];
}
My rails controller
skip_before_filter :verify_authenticity_token
respond_to :raw
before_filter :read_file
def read_file
data = params[:data].tempfile
data_compressed = ''
File.open(data, 'r') do |file|
file.each do |line|
data_compressed.concat(line)
end
end
#json_data = Zlib::Inflate.inflate(data_compressed)
end
def an_action
#processing stuff
response = Zlib::Deflate.deflate(j_response)
send_data #json_response.to_s
end
Heroku logs shows that the controller action is hit but nothing more from the logs
2015-05-05T22:39:29.860161+00:00 heroku[router]: at=info method=POST path="/api/login" host=[my app].herokuapp.com request_id=9d9c91b1-2ce2-4db5-9b54-3dea0322e211 fwd="197.237.24.179" dyno=web.1 connect=4ms service=12ms status=500 bytes=1683

After shifting my focus from Heroku to the Android code I figured out that there was an endless loop at this section of the code:
while (responseDataInputStream.read(buffer) != -1) {
byteArrayOutputStream.write(buffer);
buffer = new byte[responseDataInputStream.available()];
}
When theres nothing to read the return value is 0 instead of -1. So I updated it to:
while (responseDataInputStream.read(buffer) > 0) {
byteArrayOutputStream.write(buffer);
buffer = new byte[responseDataInputStream.available()];
}
Something strange is that on localhost the first piece of code works and it should work on production too. The documentation states that -1 is returned if the end of stream is reached DataInputStream.read(). Maybe thats a discussion for another day, for now I'm using the second piece of code.
EDIT
This issue has haunted me for weeks and after alot of googling and tweaking of the code I would like to point out that this approach was the WRONG route. The code worked on a WIFI connection but always failed on 3G. So i'll list the code changes that finally worked.
use HttpURLConnection instead of URLConnection. Reason here
Increased the size of Connect and Read timeouts from 5000 to 30000 and 120000 respectively.
Revert the while condition to while (responseDataInputStream.read(buffer) != -1)
My current app is taking a picture. Once the picture has been taken, it should automatically send the picture to my webservice so i can see it being saved on my computer, just for a starter.
My current code for the android part is as follows:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE_CONTENT_RESOLVER) {
if (resultCode == RESULT_OK) {
String[] projection = { MediaStore.MediaColumns._ID,
MediaStore.Images.ImageColumns.ORIENTATION,
MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(imageFilePath,
projection, null, null, null);
cursor.moveToFirst();
imageFileName = cursor.getString(cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA));
Toast.makeText(this, imageFileName, Toast.LENGTH_LONG).show();
Log.i("Image", imageFileName);
Log.i("Image", imageFilePath.toString());
try {
bm = BitmapFactory.decodeFile(imageFileName);
if (bm == null) {
throw new Exception("no picture!");
}
new FetchItemsTask().execute();
} catch (Exception e) {
e.printStackTrace();
}
}
}
};
class FetchItemsTask extends AsyncTask<String, Void, String> {
#Override
protected String doInBackground(String... params) {
try {
Log.i("Response", "Entered doInBackground");
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bm.compress(CompressFormat.JPEG, 50, bos);
byte[] data = bos.toByteArray();
HttpClient httpClient = new DefaultHttpClient();
HttpPut putRequest = new HttpPut(URL_SERVER);
Log.i("Response", "Sending HTTP to "
+ putRequest.getURI().toASCIIString());
File file = new File(imageFileName);
ByteArrayBody bab = new ByteArrayBody(data, file.getName());
MultipartEntity reqEntity = new MultipartEntity(
HttpMultipartMode.BROWSER_COMPATIBLE);
reqEntity.addPart("image", bab);
putRequest.setEntity(reqEntity);
Log.i("Response", "postRequest is: " + putRequest);
HttpResponse response = httpClient.execute(putRequest);
Log.i("Response", "Response is: " + response);
Log.i("Response", "Status is: " + response.getStatusLine());
BufferedReader newReader = new BufferedReader(new FileReader(imageFileName));
//BufferedReader reader = new BufferedReader(
// new InputStreamReader(
// response.getEntity().getContent(), "UTF-8"));
String sResponse;
StringBuilder s = new StringBuilder();
while ((sResponse = newReader.readLine()) != null) {
s = s.append(sResponse);
}
} catch (Exception e) {
// handle exception here
e.printStackTrace();
}
return null;
}
}
For my webservice, the code i have is this:
#PUT
#Consumes({MediaType.MULTIPART_FORM_DATA})
#Produces({MediaType.TEXT_PLAIN})
#Path("/image")
public Response uploadImage(
#FormDataParam("image") InputStream fileInputStream,
#FormDataParam("image") FormDataContentDisposition contentDispositionHeader) {
String filePath = SERVER_UPLOAD_LOCATION_FOLDER + contentDispositionHeader.getFileName();
// save the file to the server
saveToFile(fileInputStream, filePath);
String output = "File saved to server location : " + filePath;
return Response.status(200).entity(output).build();
}
My log file tells me this, and i cannot figure out where the problem lies.

And this :

If you need any more code, let me know, but i thought this was what was needed. Thanks!
I had this problem as well, and I fixed it by upgrading all my Jersey libs to 2.9 in my pom.xml file. I think the root cause of my problem was that the jersey-container-servlet, jersey-container-servlet-core, and jersey-media-multipart libs were not the same version. I had 2.8 jersey-container-servlet-core and jersey-container-servlet, and 2.7 of jersey-media-multipart.
I'm going to create mobile application that works with CommuniGate Pro server.
For example, I need to make the following Android Client C - CGP Server S conversation and get XIMSS.nonce node value:
C:GET /ximsslogin/ HTTP/1.1
Host: myserver.com
Content-Type: text/xml
Content-Length: 42
<XIMSS><listFeatures id="list" /><XIMSS>
S:HTTP/1.1 200 OK
Content-Length: 231
Connection: keep-alive
Content-Type: text/xml;charset=utf-8
Server: CommuniGatePro/5.3
<XIMSS><nonce>2C3E575E5498CE63574D40F18D00C873</nonce><language>german</language><response id="s"/></XIMSS>
Example, in ActionScript 3.0 it looks this way:
var loader:Loader = new Loader();
loader.addEventListener(Event.COMPLETE, completeHandler);
var urlRequest:URLRequest = new URLRequest(...);
urlRequest.method = ...;
urlRequest.data = ...;
loader.load(urlRequest);
private function completeHandler(...):void { ... };
How will it look in Java for Android 2.1?
As Schnapple says your question seems very broad and is confusing to read and understand.
Here is some general code to send a HTTP POST and get a response from a server though that may be helpful.
public String postPage(String url, File data, boolean returnAddr) {
ret = null;
httpClient.getParams().setParameter(ClientPNames.COOKIE_POLICY, CookiePolicy.RFC_2109);
httpPost = new HttpPost(url);
response = null;
FileEntity tmp = null;
tmp = new FileEntity(data,"UTF-8");
httpPost.setEntity(tmp);
try {
response = httpClient.execute(httpPost,localContext);
} catch (ClientProtocolException e) {
System.out.println("HTTPHelp : ClientProtocolException : "+e);
} catch (IOException e) {
System.out.println("HTTPHelp : IOException : "+e);
}
ret = response.getStatusLine().toString();
return ret;
}
