Android :: Android - Trusting All Certificates Using HttpClient Over HTTPS
Apr 15, 2010
Trying to get HTTPS working with the HttpClient. I can't seem to find an example anywhere that works for me. Basically, I want my client to accept any certificate (because I'm only ever pointing to one server) but I keep getting a javax.net.ssl.SSLException: Not trusted server certificate exception.
So this is what I have:
CODE:.............
And here's the error I'm getting:

I am using httpclient for my android app and I have a local site which has a few https pages. Since default httpclient doesnot allow self-signed certificates I am using "EasySSLFactory" and "EasyX509TrustManager", which are mentioned in httpclient documentation.
CODE:.......
The problem is if I use this SSLFactory in my android app, I am getting correct response from my site's https pages, but I get "SSL handshake failure: I/O error during system call, Unknown error: 0" for sites such as "gmail.com", "ymail.com". If I don't use. "EasySSLSocketFactory" I get response from these sites but get exception for my site.
This page fetch code works fine as a standalone java application.

I'm new to implementing HTTPS connections in Android. Essentially, I'm trying to connect to a server using the org.apache.http.client.HttpClient. I believe, at some point, I'll need to access the application's keystore in order to authorize my client with a private key. But, for the moment, I'm just trying to connect and see what happens; I keep getting an HTTP/1.1 400 Bad Request error.
I can't seem to make heads or tails of this despite many examples (none of them seem to work for me). My code looks like this (the BODY constant is XmlRPC):

I have Android pet-project DroidIn which utilizes HttpClient 4 (built into Android) to do some form based authentication. I started noticing that people who are using WiFi are reporting connection problems. It also doesn't help that site I'm accessing has self-assigned certificate. Well - the question is (I'm quite vague on WiFi details) If WiFi at the hotspot doesn't support HTTPS would that be a good enough reason for connection to fail and is there anything that I can do beside proxying into another appserver using HTTP which then would call HTTPS site?

I got one blog which interacts with servlets... Link as follows
http://groups.google.com/group/android-developers/browse_thread/threa...
In that program 2 libraries were used..
1---> import org.apache.commons.httpclient.HttpClient; 2---> import org.apache.commons.httpclient.methods.GetMethod;
When i check these libraries in my program, its show error....how to resolve this error?

I'm looking for a way to get the certificates from a package that are used to sign it. Using the PackageInfo class it is possible to get the signatures. But what can I do with signatures if I don't get the public keys to verify these.
The next question I have where does the PackageInstaller verify the signed APK file? The PackageParser class loads the APK file into a JarFile object but does this automatically verify the signature?

I'm using the Email application. I get a "non-trusted certificate" error when setting up mail for IMAP. This is expected because I generally self-sign my certs. Though, what is not expected is that there seems to be no mechanism to accept non-trusted server certificates. No self-sign certs? That's a deal breaker. There has got to be a work-a-round.

Is there a way to view the Pre-Installed Root CA SSL Certificates in the Android OS? That is VeriSign, GeoTrust, Etc.

From the signing documentation at http://developer.android.com/intl/zh-TW/guide/publishing/app-signing.html:
When the system is installing an update to an application, if any of the certificates in the new version match any of the certificates in the old version, then the system allows the update.
This indicates that an application can be signed with multiple certificates.
This is an interesting option to allow multiple entities to sign an application. e.g: A system application which was initially signed by the device's manufacturer. Further updates could be signed by the developer.
Am I misreading the documentation or is this really possible? If so, how?
Is there any other way for an application to support different certificates and with that, having two or more entities sign it?

I recently formatted my computer and updated to Windows 7. I backed up my keystore and tried to sign my apk with it but it gave me an error that said my certificate expires in 22yrs. which is just shy of what the market requires to upload the apk. So now I am stuck not being able to update my app... Is there a way to extend the lifetime of certificates so that I can update my app?

I'm working on an Android app that requires both client and server certificate authentication. I have an SSLClient class that I created that works beautifully on regular desktop Java SE 6. I've moved it into my Android project and I'm getting the following error: "KeyStore JKS implementation not found".I've looked online a bit and it looks like there's a possibility that Java Keystores are not supported on Android (awesome!) but I have a feeling there's more to it than that because none of the sample code I've found resembles what I'm trying to do at all. Everything I found talks about using an http client rather than raw SSL sockets. I need SSL sockets for this application.

I did some modification about the java code and AndroidManifest.xml of "com.android.settings" package.
Then I ran the emulator like this: make; lunch 1; emulator &
When PackageManagerService was scanning the "/system/app/Settings.apk" packages at boot time, it reported an error that "com.android.settings has no certificates at entry AndroidManifest.xml".
I guess my modified "Settings.apk" could not pass the signature verify.
How can I run my modified "Settings.apk" successfully?

I am attempting to connect to a local HTTPS server using the apache DefaultHttpClient on a Android device.
CODE:.......
I am getting an error of "javax.net.ssl SSLException: Not trusted server certificate" when the .execute runs. I want to simply allow any certificate to work, regardless of if it is or is not in the android key chain.
I have spent about 40 hours researching and trying to figure out a workaround for this issue. I have seen many examples of how to do this but none so far have worked in Android; they seem to only work for JAVA. Does anyone know how to configure, or override the certificate validation used by the Apache HttpClient in Android so that it will just approve all certificates for a DefaultHttpClient connection?

I am trying to get an image from a https url but it doesn't seem to display and get the image correctly but works fine on my computer browser. I have tested out a http url pointing to a different image and it works fine. My code is below:
public Bitmap getContactPhoto(String url) {
Bitmap pic = null; try { pic = BitmapFactory
.decodeStream((InputStream) new URL(
"https://mail.google.com/mail/photos/static/AD34hIjbK2m-Lj333E4nBcCkBC3MYl2tTs0xizuSqUOP3-Jd6DOrpFg1M5HG8jXh0MuPbeFepInZZDu92Dx8ST4b59EbOKmfYTortuuO3P1_Ohyu7b7a3gc")
.getContent()); } catch (MalformedURLException e) {
// TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) {
// TODO Auto-generated catch block e.printStackTrace(); } return pic; }
Here is the code from the activity class that calls the method above:
private ImageView mContactPhoto; private ContactDetailsViewHelper mViewHelper;
mContactPhoto = (ImageView) findViewById(R.id.contact_photo);
mViewHelper = new ContactDetailsViewHelper(mContext);
mContactPhoto.setImageBitmap(mViewHelper.getContactPhoto(mDetail.getImageRef()));
ignore the mDetail.getImageRef, that passes the real url value but for this case I tried hard coding the url as you can see from the getContactPhoto method.

How to collect URLs of all http/https requests made by the phone as well as well as the return status code and user agent from the headers. This information should be coming for all browser requests and other applications too.Please let me know this information can be retrieved on App level or we have to go to system level for this.

I downloaded Android SDK when I run setup, it displays the following error message.
Failed to fetch URL https://dl-ssl.google.com/android/repository/repository.xml, reason: HTTPS SSL error. You might want to force download through HTTP in the settings.

I'm creating an app for the Android platform which will connect with just one site using HTTPS. It is essential that it won't be able to connect to any other sites, even with valid SSL certificates. I want it to be resistant to every form redirection (for example to site pretending to be the one I need to connect with) or other "attacks". Unfortunately I cannot find any good tutorial about SSL in Android.Do you know any? I'd be grateful for some links or advices. Or maybe could you give me some code snippets? My app is prepared to use HttpURLConnection or HttpClient - it makes no difference which path will I choose.

I need to do is download some basic text-based and image files from a web server that has a self-signed SSL certificate. I have been trying to figure out how to use HttpClient to do this, but getting the SSL to work is a nightmare that seems to be way too much trouble for such a simple task. Is there a better way to perform these file downloads? Perhaps through a WebView or Browser feature? Reinventing the wheel of making a simple HTTPS GET request is a major pain, and is significantly holding up my development schedule.

So I have the following code.
StringBuilder sb = new StringBuilder(4096);
while (true) { int i = in.read(); if (i == 0) break;
else if (i == -1) throw new EOFException();
sb.append((char)i); }
What I see (with thousands of times run) is that this code takes about 1ms for every 7-10 bytes read. So reading just 10k takes almost a second!

I'm trying to load https requests with a Webkit object but It shows only a blank page, with http requests I don't have problems, It shows the page correctly. I have look the source code of the browser, in http://android.git.kernel.org/?p=platform/packages/apps/Browser.git;a... but I don't understand how the browser process the https requests. I think that the class BrowserActivity process the http and https requests but I don't see how to do it. Somebody could explain how the browser process the https request? It uses a Webview object to show the response of the https requests?

I am trying to stream video over https from Android browser. If the video URL is http, everything works fine. But when I switch the url to https, no video can be played. I tried 2 methods to stream over http/ https through Android browser.
1. Use html5 Video tag on browser (Android 2.0+ device) and call video.play( ) from javascript. - With Https url. Browser launches media player and the player displays alert dialog saying "Can't play video". I captured the client TCP traffic and found no SSL handshake between client and server. It looks like the player pops up the alert on any https link. - With Http url. Browser launches media player and the player can stream the video successfully.
2. Use direct link of html <a> tag on browser and click the link - With Https url. Browser downloads the video file without launching the player. The browser seems not try to load any https link in media player. - With Http url. Browser launches media player and the player can stream the video successfully.
So the above tests make me think Android media player cannot play media from any https url.

My work has free Wifi available for patients and whoever but you must first sign in on a main page it redirects to if your not already. Here to sign in you must accept a security certificate to be able to do this. It worked on my Droid the first day I did this and now I cannot get it to work, says it cannot redirect with no connection. Now this has happened before with my laptop and I just remove the certificate and it gets a new one and off I go. My question is where can I find these so I can delete it on the droid?

I haven't used the Java HttpClient before and the documentation is confusing. Say I want to send a POST to the URL "https://domain/foo/ bar". I'm accessing a server with an XML API that defines the message to send like this:
code:.........
And the response to expect like this:
code:..........
Now, I can build and parse the portion inside the serverapi tags but I'm not sure how the HttpClient handles the header. If I use the standard code like this:
code:...........
In the area shown as "not sure", should I pre-pend the entire header in front of the xml section, just as it's shown in the server API document or does the client take care of the first line, since it knows the URL?
Is there a way to see exactly what is about to be sent right before I call HttpClient.execute?
As for parsing the response, I believe I can just do this:
code:..........
Or do I need to strip anything off the response content before I start parsing the xml? I took a few stabs at this and it looks like there's some HTTP bookkeeping information at the start of the response content.

I want to connect to a server using ssl/https connection. During handshake between client and the server, I want to have server certificate authentication as well as client certificate authentication. The server certificate authentication is successful. But I don't know how to send client certificate to server for authentication, during the handshake.

I'm using ksoap over https to request data from a server. It works fine, but only every other time! Looking at the traffic with wire shark it seems that on every other request something goes wrong with the ssl traffic/handshake (data doesn't even get sent except for an fc-fault coming back). Doing the same requests using curl the server always responds fine and afaik the iPhone version of the program also doesn't seem to have any problems with the server.

In short, I am writing an Android application that I want to have pull data from a remote database. I was looking into .NET web services, but this http://stackoverflow.com/questions/297586/how-to-call-web-service-with-android question pointed me away from that direction.
Is REST as simple as writing some short PHP to handle something like https://www.example.com/data.php?employee=michael and have it return relevant XML or JSON data? That to me seems like what has been described to me by various sites and videos. Also, is this the best way to do this kind of operation over the internet for mobile devices, desktop applications, etc?
