Android :: PDF In Response To POST - Android Browsers Perform Additional GET And Save That As File
Sep 25, 2010
My Django view generates a PDF via pycairo in response to a POST (I'm not redirecting in response to the POST). When I POST using desktop browsers I can save and/or view the PDF using Adobe Reader or Document Viewer. However, when I POST via my android browsers the Adobe PDF Reader and the ThinkFree viewers both report the file as corrupted.
Looking in the logfiles on my appserver both Android browsers are sending a POST followed immediately by a GET for the same page:
CODE:.....
When I look at the file saved to the phone it is the HTML of the GET request.
Here's a skeleton of the view:
CODE:...........................
So I'm wondering what could be causing the android browsers to perform the GET?

Let's say I want to perform a quick HTTP post to a website within my android app. If I were to set up the http client and send the post all in the onCreate method of the main screen (inside the UI thread) just for testing purposes, what would I use to quickly see what the response is to the post? I tried something quick and dirty below inside the onCreate method when the app first opens and nothing really happens, is there something more I need to do/obviously my toast idea is just bad.
HttpClient httpClient = new DefaultHttpClient();
HttpPost post = new HttpPost("http://forecast.weather.gov/zipcity.php?inputstring=04419");
HttpResponse httpResp;
try {
httpResp = httpClient.execute(post);
StatusLine status = httpResp.getStatusLine();
Toast.makeText(getApplicationContext(), (CharSequence) status, Toast.LENGTH_SHORT).show();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();}

I've seen plenty of discussion here about different browser apps, but I have yet to see one listing the pros and cons of the different most popular browsers available for android. The main browsers I've been able to identify are the following: If there are any others worth mentioning, please add them to the list. I would love to hear your input regarding the pros and cons of each one.

I have a class that implements a multipart file upload. The code works on every java client I've tried it on but does not work on Android, *and* it's the only HTTP request code in my Android app that doesn't play nice with my back end service. I've looked through the posts to see if other are having similar issues but so far have only found posts like this http://groups.google.com/group/android-developers/msg/c4b0270153d194d9 , which are nearly the same as mine. T The symtoms I'm seeing are that the connection responseCode is "-1" & no entries show up in the Apache access or error logs. It seems as if the request is never making it off of the android platform. The code gets right through the connection writes in the debugger with no errors, but hangs on the connection read, times out and then returns with -1. Behavior is same for real phone and emulator. As I mentioned, this code is in use elsewhere and works fine.
Does anyone know of any gotchas one needs to look out for when posting a multipart file in Android? Anything about doing a POST or a POST w/ data on Android?
I'm including the code/class below so you can see what I'm up to.
CODE:.................

I'm working on a sample application that does FileUpload using Multipart post, with Andorid 1.6 SDK the application works as expected but with 2.1 there is an issue basically the application does not execute and stays stale as soon as the upload process has started.
Basically, i use "java.net.URLConnection" for establishing connectivity with the server. Is there any changes made with the core Java API's in Android SDK 2.1 that causes this issue.

I am writing an application to upload a file from Android phone to a web server. I have tried the example from:
http://www.anddev.org/novice-tutorials-f8/doing-http-post-with-android
But it will only work for SDK 1.0 (why? Not Sure?).Can this be done for Android 2.1? Or is there any other method to load a file from Android to a webserver?

Trying to figure what's wrong with my codings. I followed a blog post from here. I managed to get the codes to actually upload the file to a PHP web service. However, for some reason although I've set explicitly the MIME type for the file, PHP shows that the MIME is just a blank string and therefore rejected.

I am developing an Android app which enables the user to upload a file to services like Twitpic and others.
The POST upload is done without any external libraries and works just fine. My only problem is, that I can't grab any progress because all the uploading is done when I receive the response, not while writing the bytes into the outputstream.

Back when we all found out about the bad gps on this phone there was talk to file a complaint against att for false advertising of gps capabilities with the Captivate. Well, I was pissed and went ahead and filed the complaint. I received a letter in the mail a few weeks ago that the FCC had received the complaint.Today, I received a response from ATT in my inbox.

I am trying to find the best way to save files to the phone. Basically I have an XML file on a web server that I would like to be able to save on the phone. Should I create a specific folder in my project to save to and if so how do I save the file. Or should I make it to where when you click the Save button it checks for an SD card and if there is and SD card create a folder (if one isn't already there) and save the file in the new folder or save it to the phone? If someone could explain the most efficient way of saving files for my app and how to save the file from the web server I would greatly appreciate the insight. Any tutorial links would be awesome.

I am still not able to save a picture when I send an intent asking for a photo to be taken. Here's what I am doing:
Make a URI representing the pathname
android.content.Context c = getApplicationContext();
String fname = c.getFilesDir().getAbsolutePath()+"/parked.jpg";
java.io.File file = new java.io.File( fname );
Uri fileUri = Uri.fromFile(file);
Create the Intent (don't forget the pkg name!) and start the activity
private static int TAKE_PICTURE = 22;
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE );
intent.putExtra("com.droidstogo.boom1." + MediaStore.EXTRA_OUTPUT, fileUri);
startActivityForResult( intent, TAKE_PICTURE );
The camera activity starts, and I can take a picture, and approve it.
My onActivityResult() then gets called. But my file doesn't get written.
The URI is: file:///data/data/com.droidstogo.boom1/files/parked.jpg
I can create thumbnail OK (by not putting the extra into the Intent), and can write that file OK, and later read it back).

I love how SharedPreferences work in android and I would like to know if there is an easy way to save them to another file so I could load a previous instance of the prefs and vice versa. Basically when you load this file, all the preferences would change to how you had it before at once. I want to be able to swap 3 or 4 different versions of the same pref keys in this way. Is there an easy way to do this?
