Android : How To Convert SDP Data From Byte Into Object?
Mar 18, 2010
I am currently sending and receiving SIP messages across a network. When I want to add SDP data to a SIP message I use the SessionDescription object in jrtp. This object is then added to the SIP message. But when I get a SIP message from the server its SDP is in a byte[] array. So I'm wondering is there anyway to convert the byte[] back into a SessionDescription object so I can use the SessionDescription object's methods to parse the data?

I have to convert a byte array to string in Android, but my byte array contains negative values. If I convert that string again to byte array, values I am getting are different from original byte array values. What can I do to get proper conversion?

I am trying to get a FileInputStream object on an image that the user selects from the picture gallery.
This is the android URI returned by android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI content://media/external/images/media/3
When I try to construct a java URI object from this object, I get an IllegalArgumentException with the exception description Expected file scheme in URI: content://media/external/images/media/3 whereas the android URI shows the scheme as content
Never found a solution for the original question. But if you want the byte stream of an image in the pictures gallery, this piece of code will do that.

I want to convert this into a File object, and only a File object - I need to pass it to another constructor that requires a File. How can I convert a URI like this to a File object? If I try File newFile = new File(myURI);I get an error in Eclipse suggesting that I should convert the URI to a String. Supplying URI.getPath() in the constructor doesn't help either.
This relates to the 'How can I convert android.net.uri object to java.net.uri object?' question, which unfortunately seems to have no good answer, but I want a File object out, not a java uri. I don't mind if I have to write it to a bytestream and back again - whatever is the best way.Apologies if I'm cross-posting my own question, but I thought I might need to make things a bit clearer.

I am developing an Android application and require some basic datetime manipulation. I have a Date object (from Java.util.Date) holding a specific date. I need to add a specific time to it. The time I have is a string in this format: "9:00 PM EST"..How would I "add" this time to the previous date? If the Date object currently has: "4/24/10 00:00:00"
How would I change it to instead be: "4/24/10 09:00:00 EST"..I would prefer to do this without the use of an external library, if possible.

I am trying to figure out how to do conversion of Picture object generated by web View to Bitmap for later JPEG encoding and saving to local f/s. I tried to create a bitmap from pre created Picture object by BitmapFactory.decode Stream and failed. Seems like Picture object is unrecognized format by Bitmap factory. Just wondering is there any method to do the conversion?

I have a library that takes a File object as a parameter to one of the functions.
I am getting the file like this:
this.openFileOutput("myFile", MODE_PRIVATE)
I need to load this file from the system, however, I don't know how to convert FileOutputStream to File. Or is there another way of doing this?

I wish to display data in the the arraylist in a list view. The arraylist is not a generic list but a object defined by me. I want to display only certain data of the object. Something like, an object of a student, I want to display the student's name only, the student id and the student dob is not required.

I have created a class with 3 sub classes in Java. The 3 sub classes contain variables to store information from my XML document. I am able to store in the first two for there are only single instances of the data in the XML. The third class contains variables that repeat multiple times. I want to store an object of "third class" objects. I also have a SAX parser class. I am doing this within an Android environment (1.6).
Does this make enough sense without displaying any code?

I have created an android app. It sends a data message on a port for communicating with the same app on some other phone. While sending the message, i have encoded it into binary data using ISO8859_1 encoding.
byte[] b1=payload.getbytes();
I am able to receive the data message at the receiving end. But the problem is that after receving it in binary format , My app needs to decode the message back to string or human read-able format. But i am not able to do the same.
I have tried to convert it into String using 'toString()' but string contains binary character .

I am looking into developing an App that will convert a website into more readable data for an android app. I am at university and have an online notice board which can be viewed on the web but if possible I would like to transfer this into an app on android to make it more easy to read on mobile devices.
What I thinking is that the app would go to the website where the notice board is held and read in the html code to display each notice in a list adapter view. Each notice is within its own div so I assume I could use that to split each notice up into its own button on the list adapter view. Is this possible and if so how I can go about doing this. I have tried google for an answer but I have not yet found a solution to this problem.

My input is a InputStream which contains an XML document. Encoding used in XML is unknown and it is defined in the first line of XML document.
From this InputStream, I want to have all document in a String.
To do this, I use a BufferedInputStream to mark the beginning of the file and start reading first line. I read this first line to get encoding and then I use an InputStreamReader to generate a String with the correct encoding.
It seems that it is not the best way to achieve this goal because it produces an OutOfMemory error.
Any idea, how to do it ? code...

I am dealing with http post method on Android. I have successfully send simple string pairs using HttpClient and HttpPost class with the NameValuePair as entity. However now I want to send a simple array of bytes[]. Unfortunately the only entities I have found for the HttpPost class are the NameValuePair and FileEntity. However my byte[] is not from a file. Wirting it to a file and then sending by the FileEntity seems to be pointless and stupid. How can I send this array using default HttpClient and HttpPost class?
