I have been working with the HttpsUrlConnection class and have found an interesting issue, it seems to fail on every other connection. The first request connects to the server successfully but the second one always fails. Any ideas on what i may be doing wrong.
Here is my code.
code:.................
I use the following code snippet to connect to a server and retrieve some data:
HttpsURLConnection con = (HttpsURLConnection)myurl.openConnection(); InputStream ins = con.getInputStream();
The code mostly works fine. If I leave the app for a few minutes, and return to it and make another request, I receive an IOException: Broken Pipe.
Once it has failed one time, it immediately works again, and will continue to do so until I leave it for a while once more.
I don't know if this is an Android specific thing, or general Java, but it doesn't happen on my desktop test version.
I'm suffering from this for a week, i was trying to use the famous SeekBarPreference in a dialog - http://android.hlidskialf.com/blog/code/android-seekbar-preference
I copied the class from above link into my project. Then created the xml as brightness.xml:

Finally I try to integrate it as custom dialog:
CODE:...................
But always getting error: "Error inflating class java.lang.reflect.Constructor" at this line "<com.yoomap.anymode.SeekBarPreference" in the xml
Root cause: ClassCastException on SeekBarPreference.

I can't explain why, I followed the app sample on http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/LocalServiceBinding.html.
I am using HttpsURLConnection to post data to a web server.
Here is the function I wrote to get the result. (see the code below)
Very strangely, when the function be first called in my program it would very likely return -1; and then I re-call the function after the first call, it would always work ok.
So I wonder if there is anything I am missing in the code that when the function be firstly called, the missing party is be "initialized", in that the followed call goes OK.
Here is my code of the function:

I'm hoping someone could help me out with intermittent connections I'm getting using code with HttpsURLConnection.
The code I'm using is below:
CODE:...............
The connection works the first time everytime when I use it to pull a json file. However, when I use the connection again to send a command, it always fails the first time. It then typically works if I send the
command quickly ( within 5 seconds), but fails if I wait a while. I don't think its a SSL issue because it connects the first time correctly, but I could be wrong here. I also tried many different
variations such as adding:

However, I had no luck. Any help would be greatly appreciated.
I think I'm experiencing the same as http://groups.google.com/group/android-developers/msg/9d37d64aad0ee357
This is Android 1.5 SDK. I happen to call several times below code(which is in a method) with
the same url and it fails intermittently. When it fails, there is no exception, the stream is empty so the
readConnection fails, and getResponseCode returns -1. Global caching is disabled, setDefaultUseCaches(false);
I suppose there must be some kind of url connection object pool somewhere.
How can I workaround this?

I try to build an https client for android and i need do get some request of an Servlet but when i use the getInputStream method the applicaion hangs.
There is no error only hanging when i call the method.
CODE:..................
This is only to check the call, but it didtn work.
the subscribe method works, when i comment out the line with the inputstream, the server show me all is correct. I can try the same with the Firefox and it works and i can see the request. i also put the keystore into the TrustManager.
I'm a problem with a HttpsURLConnection that I can't seem to solve. Basically, I'm sending up some info to a server and if some of that data is wrong, the server sends me a 500 response code. However, it also sends a message in the response telling me which bit of data was wrong. The problem is that the message is always empty when I read it in. I think this is because a filenotfound exception always gets thrown before the stream can be read. Am I right? I tried reading the errorstream as well but this is always empty.
Here's a snippet:

I'm sure there's a simple answer to this, but...Why can't I nest another view type within a View element? In my layout file I try:

And this gives me a ClassCastException. Why?
I have some Android code that can send files to my webserver using an HttpsUrlConnection, but when it tries to send larger files I get an OutOfMemory exception when opening the OutputStream. Can anyone offer some assistance?
It looks something like this:
code:..............
This is where I try different things. The closes solution has been: httpConn.setChunkedStreamingMode(1024); In this case, I don't get the OutOfMemory immediately when opening the OutputStream, but I see the heap growing as I os.write() and it eventually runs out.

I've got a problem with my application when I make a number of requests using the HttpsUrlConnection class.
My program makes the first request using the HttpsUrlConnection class to retrieve a file. It then makes a second request to the same server to retrieve a different file. What happens however is that periodically I'm getting a -1 HTTP response code on the connection.
When the failure occurs between the two requests I see the following line of trace in logcat:
D/OpenSSLSessionImpl( 699): Freeing OpenSSL session
This seems to happen fairly consistently. If I retry the second request after it has failed it generally works and I get the requested file from the server.
Note that if I don't see the OpenSSL session being freed the second request works fine the first time.
Some other information:
1) I'm not calling disconnect on the connection
2) I'm don't always read the entire file from the server after the first request
3) I always close the InputStream in the event that I get an InputStream on the first connection
How to prevent the OpenSSL session from being freed.

I am new to java, eclipse, and android development, so I may be missing something simple although I have checked basic stuff like spelling several times.
Because there is no number picker control (such as that used in the date picker) in the public Android SDK, the conventional wisdom is to "clone and own" the control that exists in the Android source.
In an attempt to do that, I have copied the code for NumberPicker into my project and its dependency, NumberPickerButton. I have also copied the supporting resources.
The problem I am having is that when I try to include the NumberPicker in a layout, the rendered version of the layout within Eclipse does not work.
CODE:...............
Adding that tag causes the Layout view of the XML file to only show the following error.
ClassCastException: com.spencerandbrown.PatientTracker1.NumberPickerButton cannot be cast to com.spencerandbrown.PatientTracker1.NumberPickerButton
I have tried both the fully qualified name and the unqualified name and it makes no difference.
The strange thing is that the control works at run time, it just will not render in Eclipse.
Is there a solution for this issue? Am I just doing something wrong?
If necessary, I can include more code from my project to clarify.
If I reference the internal Android widget, it works fine in the Eclipse layout view, but it is clumsy to interact with that way and it might break in the future.

Here is the stack trace from Eclipse.

This is probably related to this question. I want to know if anyone else gets the same error as me and if there is a way to get around this. I did the following: Followed the instructions from this page. From the top, go to File -> Create a new project -> Android Project -> Create project from existing sample. Checked Android 2.2. From the drop-down menu picked SkeletonApp. Clicked finish. From the package explorer, went to SkeletonActivity -> res -> layout -> skeleton_activity.xml. In the tabs at the bottom of the editor area (editor area is the center of the screen) clicked on Layout. Then I got the error "ClassCastException: android.widget.EditText cannot be cast to andoid.text.ViewGroup". The full text of the error message is given below.

I've been trying to add a linear layout to a listview header. The listview appears fine and is working as expected, but when i try to add a linearlayout to the header i get a java.lang.ClassCastException: android.view.ViewGroup$LayoutParams occuring at the list.addHeaderView (ll); line. I thought it might be something in the complex layout i had so i switched it to just a linearlayout with a colored background and still got the same error. The end result i an trying to get is a list with a header that is all scrollable.
View 3 Replies View RelatedI'm having a big issue with a static HTTPS connection method. Every second request fails and HttpsUrlConnection.getResponseCode() returns -1. So every second call works well, returning data as expected.
It's the method of a static class I'm using in different corners of my application. I would guess there is anything I don't clean up correctly when the method returns the first time and that whatever causes a problem might get destroyed through a second call of the method. But I'm having a hard time finding any clues.
I'm currently using this class to talk to hosts with invalid SSL certificates. Not going to use this in the final version of the app, but right now I need to save money. ;)

I've run into an early problem with developing for android. I've made my own custom View (which works well). In the beginning i just added it to the layout programmatically, but i figured i could try putting it into the XML layout instead (for consistency).
So what i got is this:
main.xml:
CODE:..........
(Theres obviously more, but you get the point)
Now, this is the stacktrace:
CODE:...........
Why cant i cast my custom view? I need it to be that type since it has a few extra methods in it that i want to access. Should i restructure it and have another class handle the logic, and then just having the view being a view? I'd really like this to work though.
Why do I get java.lang.ClassCastException when I tried to cast back an array of custom object that implements Parcelable?
Here is the custom class:

I am writing a adapter for a specific app, the problem I met is:
I have only 1 listview in main.xml, and the row style is defined in file_row.xml. If I simply use list.setAdapter(new ArrayAdapter<String>(this, R.layout.file_row, R.id.file_name, items)); where items is a ArrayList<String>, everything works well.
But if I use my custom Adapter, say, list.setAdapter(new MyOwnListAdapter(this, filename)); and in the class of MyOwnListAdapter, the code has been simplified as
CODE:................
But I always met the problem which is:
CODE:.........
I thought the self-defined Adapter class actually has only one line of valid execution, which is super(context, R.layout.file_row, R.id.file_name, filename_list); It's essentially identical to direct calling of list.setAdapter(new ArrayAdapter<String>(this, R.layout.file_row, R.id.file_name, items)); Then why I always got this error if I call my own Adapter?

Is there something missing from this? Some questions have talked about having this problem when creating a dialog from onCreate, which happen because the activity isn't created yet, but this is coming from a call from a menu object, and the appContext variable seems like it is correctly populated in the debugger.
I'm writing an application which connects to a back office site. The backoffice site contains a whole slew of JavaScript functions, at least 100 times the average site. Unfortunately it does not load them, and causes much of the functionality to not work properly. So I am running a test. I put a page out on my server which loads the FireBugLite javascript text. Its a lot of javascript and perfect to test and see if the Android WebView will load it. The WebView loads nothing, but the browser loads the Firebug Icon. What on earth would make the difference, why can it run in the browser and not in my WebView? Any suggestions.
More background information, in order to get the stinking backoffice application available on a Droid (or any other platform except windows) I needed to trick the bakcoffice application to believe what's accessing the website is Internet Explorer. I do this by modifying the WebView User Agent.Also for this application I've slimmed my landing page, so I could give you the source to offer me aid. package ksc.myKMB;

1- Does Android Browser (Éclair code base) support the "plug-in" or not?
2- Why "Google Gears" support is removed from the clair code base?
I searched the forum and came to know that earlier version of the Android does not support it at all? Here is the link for that, but this query asked in Dec'2008.
At first,I have a database created by using Ruby on rails.I just already implement insert function(HTTPPost) in my Android Application and it's work.But I don't know how to retrieve specific record from my databases and insert it back to specific record in Android (Like edit function in RoR)This is my insert code :
private void insertComment() {DefaultHttpClient client = new DefaultHttpClient();HttpPost post = new HttpPost("http://10.10.3.87:3000/comments");
// Configure the form parameters
List<NameValuePair> nvps = new ArrayList<NameValuePair>();
nvps.add(new BasicNameValuePair("comment[content]", t_comment.getText().toString();
nvps.add(new BasicNameValuePair("comment[id_account]", "1"));
nvps.add(new BasicNameValuePair("comment[id_place]", Integer.toString(position)I really try many ways out but it doesn't work and it takes very long time to fight with this piece of code. Actually, I really don't know how to specify RowID to HTTPPost.
I am doing some android development, and now I need to send some android application generated data onto a remote server (a database)?How can I do that? can I use direct JDBC connection and sql?
