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?

Android :: Storing Double Values In SQLite / How To Ensure Precision?

Jun 21, 2010

i have a problem with double values i need to store in an android homed sqlite database. since these double values represent gps values (lat & lng), i really NEED an absolute precision down to the 9th number after the comma.when reading lng from this table into some (java) double variable, i get a value like "0.999956837" - this renders the values pretty useless to me.is there a way to enforce the precision i need other than storing the values as "text" fields (what would make expensive casts neccessary) or storing them as integers (meaning i need to multiply/divide at each write/read-op)?

Android :: Speed Of SQLite Vs List Contains For "in-set" Icon On List Rows

May 9, 2010

An application I'm developing requires that the app main a local list of things, let's say books, in a local "library." Users can access their local library of books and search for books using a remote web service. The app will be aware of other users of the app through this web service, and users can browse other users' lists of books in their library. Each book is identified by a unique bookId (represented as an int). When viewing books returned through a search result or when viewing another user's book library, the individual list row cells need to visually represent if the book is in the user's local library or not. A user can have at most 5,000 books in the library, stored in SQLite on the device (and synchronized with the remote web service). My question is, to determine if the book shown in the list row is in the user's library, would it be better to directly ask SQLite (via SELECT COUNT(*)...) or to maintain, in-memory, a List or int[] array of some sort containing the unique bookIds.

So, on each row display do I query SQLite or check if the List or int[] array contains the unique bookId? Because the user can have at most 5,000 books, each bookId occupies 4 bytes so at most this would use ~ 20kB. In thinking about this, and in typing this out, it seems obvious to me that it would be far better for performance if I maintained a list or int[] array of in-library bookIds vs. querying SQLite (the only caveat to maintaining an int[] array is that if books are added or removed I'll need to grow or shrink the array by hand, so with this option I'll most likely use an ArrayList or Vector, though I'm not sure of the additional memory overhead of using Integer objects as opposed to primitives).

Android :: Autocomplete List From SQLite With Criteria

Jul 3, 2010

Can someone point me to right direction, how to create an adapter for AutoCompleteTextView, which would be getting data from SQLite DB, using data, which user entered into the text field? I want to use the user-entered data to filter suggestions for autocompletion.I imagine that adapter should always take user-entered data as soon as changes appears and use it for fetching suggestions on-the-fly. Is that possible? So far I've seen many tutorials for autocompletion where static String arrays were used, but never seen them build dynamically.Is it possible to do it automatically or I need always fetch String array myself and pass as ArrayList to adapter on every AutoCompleteTextView change?

Android :: Multiple-choice List From The Sqlite Database In Android

Jan 23, 2010

I'm new to Android programming, and I wanted to pull list options from a column of the SQLite database for the user to select. How would I go about doing this? Like, say the database table to be read is called countries, and the columns were ID, country, and capital. How would I let the user pick from the list of capitals and have the application return the information in that row?

Android :: HttpPost And Byte[ ] ?

Jul 14, 2010

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?
