Is it possible to host a web server within an Android phone itself?
Similar to Apache. I want to access the web server from the mobile
browser itself.
Couldn't find any reference online. Is this possible?
Thanks in advance
Short: yes. If you are looking at code, check out the org.apache.http package. If you are looking at a ready app, check iJetty and kWS.
KSWEB — a suite for web development on the Android platform. It consists of: a web server, PHP programming language and the database MySQL. KSWEB allows you to organize a platform for running and debugging Web applications (sites) in your Android device. Working with the application is very simple. To start the server it is enough to run our application, select, if necessary, port and the root directory.
By default, KSWEB contains a fully functional configuration file of the server, PHP and MySQL. However, if you want something to change them, go to the server options and click on the item «INI Files». Configuration files will be moved to SD-card of your device at «/mnt/sdcard/ksweb/ini/», if available. If repeatedly clicking on the item settings «INI Files» KSWEB will use the internal configuration files.
What's in the plans?
Review the requirements for the Android operating system, in particular
reduce the requirements for the version of Android to run the application to 2.0;
Add the ability to track the flow of errors arising when working with php and mysql;
Move the log files on the server and mysql on sdcard;
Extend the additional PHP libraries. For example, pdo_mysql;
Move the database files to MySQL on sdcard.

Atjeews android app server, small footprint, biggest advantage for me was jsp support.
I recently installed BitWeb which I recommend highly. I have a rooted phone with lends me a few more options (and I also recommend rooting if you haven't and plan on doing any server tinkering at all)
BitWeb is nice in that it includes a lighttpd server, a stripped down php engine and a stripped down mysql engine giving you a quick and dirty LAMP system with just one app. I use mine in conjunction with an sshd app to gain a busybox shell, I installed nano and use the ssh connection to do an sshfs share to edit content from my pc.
Bitweb includes the ability to tweak the config settings for all three services, and I've even managed to get multiple Zend servers working on just the one little server with a little tweaking to the re-write rules and the application.ini settings.

If you want to see some of the config options I had to customize, I can either post them or respond via email with what I set up as well as some comments on the pitfalls I ran into along the way. (I recently posted one as a self-answered thread on here by the way, although it turned out not to be specific to the android platform but with lighttpd/Zend)
I'm just bummed that t-mobile/HTC appears to have no plans to upgrade my phone beyond Gingerbread as I understand some of the new android OS's have ways you can access some of the hardware (such as the cameras) from scripts or compiled code without a fuss. If I want to do it now, I either need to hard code my own interface to them or get a pre-roll app capable of doing it which really tasks my phone when running side-by-side with the web/mysql/php services.
I might be a last to answer this question but believe me, this is the simplest and latest answer in 2020 for those who need to start a webserver in Android and need to serve multiple clients without implementing any other third-party libraries.
Copy your HTML file into the assets folder of Android as server.html and declare the serverSocket as global in your class.
Run the below code inside a new thread.
try {
serverSocket = new ServerSocket(8080);
while (true) {
final Socket socket = serverSocket.accept();
new Thread(new Runnable() {
#Override
public void run() {
try {
BufferedReader is = new BufferedReader(new InputStreamReader(socket.getInputStream()));
PrintWriter os = new PrintWriter(socket.getOutputStream(), true);
String request = is.readLine();
Scanner scanner = new Scanner(getAssets().open("server.html"));
String response = scanner.useDelimiter("\\Z").next();
os.print("HTTP/1.0 200" + "\r\n");
os.print("Content type: text/html" + "\r\n");
os.print("Content length: " + response.length() + "\r\n");
os.print("\r\n");
os.print(response + "\r\n");
os.flush();
socket.close();
} catch (IOException ex) {
ex.printStackTrace();
}
}
}).start();
}
} catch (Exception ex) {
ex.printStackTrace();
}
That's all your native Android Java (no third-party libraries implemented) webserver is live at port 8080.
If you want to use DB and POST requests, try to implement SQLite and WebSocket connections to make two-way communication.

Check KSWEB and Bit Web Server,
both using Lighttpd als server, php and support mysql.
i tried KSWEB, it works wonderfull, but i don't know yet how to use the modrewrite.
but, it should be work. you can try the trial version of KSWEB before purchase it.
KSWEB costs a little bit more than Bit Web Server only 0,XX $.
if you decided to buy it, post your experience here... i want to know too... :)

If you find trouble to make it working, you can see this video : https://youtu.be/3_m3vNGTp74
Yes, it is possible. May be not so complicated as Apache, but possible.
Look at Moto Phone Portal for example, it has web-server in its base. And there were several applications for this purpose in Market.
Servers Ultimate Pro, just 8 pounds.
Include PHPAdmin, MySQL and ton of other servers. I am currently using it as proxy.
I've stored my .apk file in my rails server. I've set up a route that redirects a given url to a method that essentially sends the file
in my routes.rb file
match '/myApk.apk' to: 'upgradeapk#index'
Upgradeapk_controller.rb file
def index
#filename = '/myApk/myApk.apk'
#tmpfile = 'upgradedApk.apk'
send_file(#filename, :disposition => 'inline', :stream => true, :type=> 'application/vnd.android.package-archive', :file_name => #tmpfile)
end
When i type my sever url and add '/myApk.apk' it starts the downloading process as long as i do it on my a computer. However if i try to do it on my android device it doesn't work. Checking the download lists in my android device browser i notice that the download "job" for the apk is created, however its in an endless loop changing between states "in queue" and "downloading". Nothing ever downloads.
Do I have to set the send_file differently when it comes to making it work on android devices?
----EDIT------
Ok so i've decided to store the files in a dropbox location instead of storing it in my server. If i pass the url for the file directly in my android function for the http request, it works well. The file is found, downloaded and the installation is prompted.
class UpgradeapkController < ApplicationController
def index
android_apk = Androidaplicacion.first (Model to access the table in which i store the apk dropbox url)
route = android_apk.url
redirect_to route
end
end
I've set up my controller to redirect to the given url for the dropbox file. If i try the url (same as before, using the "match" url) in my android browser, this time it downloads. However, if I try it from the android app, its the same as before, it just doesnt download.
So, the "send_file" method seems to not be working if its on the android platform. redirecting to my dropbox url from the controller works on android but only from a browser, not using the http request on my android app. The only way to get it to work in my android app is if I use the dropbox direct link.
Also, I first thought this was because my server was running on https and the certificate its not a valid one. I found a way to bypass the https certification encryption/certificate validation thing on my android app but it didnt work either (it appeared to have succeed in avoiding the validation) but the results ended up been the same. I then ran an instance of my server using http and still same results.
I have an application in which we have files that are being served from a secure encrypted file system to the user. THe files are decrypted on the fly by the application and then pushed to the client through the response header. This works perfectly fine in all browsers and iOS devices, but fails on all androids. It just simply says the download failed.
I have tried many different solutions that have been suggested around for android devices, as they seem to have a lot of problems with files like this. Nothing has seemed to work.
change file extension to be in all caps in the Content-Disposition header
tried multiple content types (application/octet-stream and specific file types)
Below is the actual code writing the response headers.
strMimeType = objDocument.FileMime
If strMimeType = "" Then
strMimeType = "application/octet-stream"
End If
HttpContext.Current.Response.ContentType = strMimeType
HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment; filename=" & objDocument.Filename)
HttpContext.Current.Response.Clear()
HttpContext.Current.Response.WriteFile(Server.MapPath("/FS/CO/" & objDocument.DocumentID & "/" & objDocument.Filename))
HttpContext.Current.Response.Flush()
HttpContext.Current.Response.Close()
HttpContext.Current.Response.End()
this worked for me - adb logcat DownloadManager:I *:S
that shows in the adb logcat only things from the downloadmanager. i am on a samsung galaxy s4 so if you have something different and you probably do you have to find out the name of your download manager by google, or start the log : use "adb logcat" do that, and then download the file then quickly scroll up to stop the adb from printing more stuff, and then find it.
i got this problem:
I/DownloadManager( 9250): Initiating request for download id = 2011 with mAllowedNetworkTypes = -1 forP2Pbit = 8194
W/DownloadManager( 9250): Aborting request for download 2011: http error 403, mContinuingDownload: false FinalStatus = 403
i think it has something to do with my server but my server works just fine. so im not sure why it is breaking
Scenario: I am trying to debug an Android app by proxying requests through Fiddler.
I got FiddlerRoot certificate installed on the Android device, and the SSL decryption works for most requests, but for other requests I can only see the HTTPS Connect, and nothing else in the Fiddler log. I think it might be image requests over SSL that fails to decrypt.
I have double-checked that "Hide images" is off, etc. Images retrieved are hosted on another domain than the main API the app talks to.
What could cause this behaviour ? And how do I get the image requests to show in Fiddler ?
I am using the latest Fiddler4.
There are plenty of tutorials on how you can intercept HTTP(s) traffic from Android using Fiddler.
Try this one: http://docs.telerik.com/fiddler/configure-fiddler/tasks/configureforandroid
However, it will fail when you try to intercept and decrypt Android SSL traffic coming from an application, and not from a browser.
It might be that the application uses a certificate pinning – and you are probably cannot decipher this connection. Lost cause!
But more probably, the reason is a bug in the HttpsUrlConnection pipeline implementation.
To solve the issue, please proceed with the following steps:
In Fiddler click "Rules->Customize Rules";
Find function OnBeforeResponse in the script
Add following code to the function body:
if (oSession.oRequest["User-Agent"].indexOf("Dalvik") > -1 &&
oSession.HTTPMethodIs("CONNECT")) {
oSession.oResponse.headers["Connection"] = "Keep-Alive";
}
Save the file and restart Fiddler.
I am creating an aplication that involves an WebView. The thing is that I want to load the full page and not the mobile one, so I have changed the User Agent. Nevertheless there are pages that loads the mobile version.
Here are two versions of code that I have tried:
1.webview.getSettings().setUserAgentString("Mozila ");
2.
String DESKTOP_USERAGENT = webview.getSettings().getUserAgentString ();
DESKTOP_USERAGENT = DESKTOP_USERAGENT.replace("Mobile ","");
webview.getSettings().setUserAgentString(DESKTOP_USERAGENT);
This are exemples of webpages that loads the mobile version in any cases:
http://www.jurnalul.ro
http://www.androidzoom.com
1.Does anyone knows how I can trick the server and tell him I am using a desktop and not a mobile?
2.How does a website knows that I am using a mobile version?
Thank you very much,
Razvan
The problem may be that if you are using a device that your carrier is routing all your HTTP requests through a proxy, and that the proxy is changing the User-Agent. Check on the other end, with your own server, using nc -l 80 -vvv that your request is indeed sending the User-Agent that you have modified.
EDIT: Some specific troubleshooting steps
Forward a port 9090 on your router to your desktop machine or laptop.
Download netcat
Run netcat with the command "nc -l 9090 -vvv"
In your Android application's WebView, make an HTTP request with the User-Agent you are injecting to http://your.ip.address:9090
In the terminal you ran netcat, you will see the HTTP request dump in plain text. There you can check the HTTP header User-Agent to see if it has been changed by a proxy server or not.
You cannot test this stuff with Wireshark or Fiddler because it is happening in the WAN. You need to test it on the receiving end, either on a server, or on your own desktop machine.
webview.getSettings().setUserAgent(1);//for desktop 1 or mobil 0.
