SSLContext context = SSLContext.getInstance("SSL"); The above line results in the exception: java.security.NoSuchAlgorithmException: SSLContext SSL implementation not found, I'm using Android 2.0 SDK and when specifying TLS, it is accepted. How come I get the exception? Doesn't Android support SSL?

i want to implement a client for https, all in my localhost (in my apache, it is configured to ask authentication), with a resource " https://localhost:443/resources/resource1.xml" the server works fine.
I have a client for desktop, and it works fine, the resources are consumed using httpcomponents-client-4.0.3), i have readed that Android uses that version.
This is the code of my client in Android (practically is the same of desktop mapped to android) ,
in the line of SSLContext sc = SSLContext.getInstance("TSL"); the next exception is thrown :
java.security.NosuchAlgorithmException: SSLContext SSL implementation not found
I have tried with TSL and the exception continue.
Import java.io.IOException;

View 5 Replies View RelatedI've been playing around with the new LVL announced yesterday and wanted to write a policy which only stops the user when it is certain that he does not have a license. In other words, the policy will only "dontAllow" the user if the last meaningful response from the licensing service was NOT_LICENSED. Therefore, if the user is offline when they first use the app, then they will be allowed in. The idea behind this is that I don't want genuine paying users to ever (within reason) be inconvenienced by this licensing system. The downside is that all the user needs to do is clear the app data and go offline before restarting the app. The app will continue working until they go online (and restart the app). My thoughts are: 1. Most users won't know about that workaround 2. Those users that are happy to use that workaround, probably wouldn't pay for the app anyway.

We have discovered a potential bug in the implementation of AppWidgets. Here is a simple reproducer.
Attached is the code for an application containing a TestActivity and a TestWidget. TestActivity extends MapActivity and TestWidget is a simple widget provider which updates a TextView every 2 seconds. Now if the TestActivity is launched with no instance of TestWidget running, it works just fine. But if the TestActivity is launched after placing the TestWidget on the home, it results in ClassNotFoundException. Here is what we get:
CODE:.............
So it seems we have an inconsistency in the way the class loader works for the same apk.
WORKS - Launch the application by itself, without invoking the Widget. DOES NOT WORK - Create a Widget on the Home screen and then launch the application from the launcher.
The source code for this application (http://www.yousendit.com/ download/TzY3ZGVhZy96NE4zZUE9PQ) has been attached. Hope someone from the Android team can shed light on this behavior.
This error is seen on the 1.5r3 SDK. Not sure if this has been addressed in 1.6 and 2.0 SDKs..

As an aside, how have your experiences with LVL been so far? Any pitfalls? I'm not asking for anyone to share their implementation details as that would give the hackers ideas.

View 1 Replies View RelatedI would like to implement the similar widget as QuickContactBadge from which I can launch some internal activities. I checked out the source code for QuickContactBadge, QuickContactActivity etc and simplified them to accommodate our requests. It can launch and display at correct position. However, I can not see the original view below the quick contact tack no matter how I try. And I found the window created by QuickContactWindow is quite small and I tried to set the background etc. Nothing works. Who can help or give some guidance about how window works? Say, from Activity A, I click on image, I launch a new activity (or window), how can I make the Window of Activity A is still visible? Or more general, what is the best way to achieve similar behavior like QuickContactBadge?

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.

View 5 Replies View RelatedI want to use HTTPS in my application. The Java URL class does not seem to do the job.
Does anyone have any pointers?
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.
View 2 Replies View RelatedFirst I have my app running currently and its working fine, I just question how I implemented it. I come from a linear C++ background and this Activity/Intent thing is a little new to me. Here is how my app works currently (order of activities started)
("->" = Starts Activity, "<-" = Returns from activity)
MainActivity -> Login Activity <- onActivityResult function displayListOfItems ...
I am wondering if I should switch the starting intent as follows:
LoginActivity MainActivity function displayListOfItems
The issue I had with the second scenario was that pressing the back hard key would take me from the MainActivity back to the LoginActivity and I didn't like this. I guess to sum up my question, is it normal for the MainActivity to handle all subsequent starting of activities or is it common to do a more linear implementation?
Has anyone tried to write his own implementation of ViewGroup with some TextViews in it? I have a problem, that TextViews in such an implementation don't respect gravity attribute (TextView.setGravity(Gravity.CENTER);) and text is positioned in the top left corner.
If enyone is interested, I just overwrote method onMeasure() (for all my TextViews) and changed call from super.onMeasure() to setMeasuredDimension(int, int) and gravity started to work normally.
Basically, in my custom layout I use the following class to display text:

View 1 Replies View RelatedI 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.

StringBuilder sb = new StringBuilder(4096);
while (true) { int i = in.read(); if (i == 0) break;

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?
View 5 Replies View RelatedI 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.
