Android :: Read A Segment Of File In Java / Droid?
Aug 27, 2010
I'm sure this might be a simple question, but unfortunately this is my first time using Java and working the Android SDK.
I am uploading files on Android using the Apache HTTP libraries, in particular using the MultipartEntity.
I'm uploading to a service that allows me to send them chunks of the file, and once complete, they'll reassemble the chunks. I'd like to take advantage of this feature.
Here's the scenario.
File FOO.BAR is 20 MB. I'd split it into some arbitrary chunk size, let's say 1 MB, which means 20 chunks. Chunks #3 and #14 fail (maybe the cellular/WiFi connection was bad). I can now re-upload just these two chunks and everything will be good.
What I'd like to know is how can I read only part of a file (like the data between 3MB and 4MB)?
The file piece should be an InputStream or File object.

I am new to Android and relatively new to Java so please bear with me. I have an XML file stored in the res/xml that I am trying to write to. I know how to read it using XmlResourceParser, but I have not been able to find a way to write to that file locally. Could someone point me in the right direction please.

Is there anything the Dalvik VM supports (in terms of bytecode) which is not used currently because the .class files don't have it?
As an example, if people would write their own Source-to-DX converter for their functional language XYZ, would they be able to implement e. g. full tail calls although the .class file does support tail calls only under certain circumstances?

I do an import of the full package name / java file, and if I do a <classname>.<method>, SOMETIMES I can get it to access - other times I get a lot of can't use a static in a non static bunch of talk. I'll admit I'm new to Java, so what do I need to do? Call a class instance first, then call my methods? I'm rather confused by this, as I want to put all of my 'functions' into a FunctionsList.java file, and all of my main Activity (UI) into a MyActivity.java file.
For example:
<MyActivity.java>
import com.example.FunctionsList;
private class MyActivity extends Activity {
FunctionsList.function();
}
9/10 times I get that static/non-static error. If I put all of my functions into MyActivity.java, I have zero problems!

Is there any class generators to process web services in Android/Java? I may have to write my own to generate classes against WSDL but I'm trying not to. Also is there one for REST services as well?
If not providing me with discovery service suggestions like disco/wsdl are good enough.

I have an application which we are writing to be both a MIDP application using LWUIT as well as an Android application.
We attempt to share as much common code as possible between the two platforms.
I'd also really like to be able to share the localization strings when possible.
Reading through the docs in:
http://developer.android.com/guide/topics/resources/resources-i18n.html
It looks like Android uses an XML format to specify name-value pairs, e.g.:
{{{ <string name="go_online_message">You are currently offline. Go online? This will use the data network</string> }}}

I am creating an application for the android, and would like it to be able to read a text file via anonymous FTP. I've tried URLConnection, but it doesn't seam to be working. After some Google searching it appears that URLConnection doesn't always work with some FTP servers. All of the java FTP connection libraries I've found require you to download the file to a local location before reading it. However I would like to have the same functionality as URLConnection in that I can just use the following similar code...
