Android :: Downloading Mp3 Files In Java On Android
May 4, 2010
What is the best way to download an mp3 file in java (on Android sdk)? http://developer.android.com/reference/java/net/package-summary.html Should I be using sockets? If so - what kind of "Stream" reader should I use. I have also read something about "intents" - is this something that is applicable here? I am also curious as to what should one do if connection gets interrupted - can I resume the download somehow or restart it.

Anybody know where one can obtain the source code for dx all in one downloadable blob?
The following gives dx a file at a time:

My mother has an Asus Transformer, and she's had it for awhile, but she doesn't use it for much other than getting e-mails or video chats. I turned it on today and it suddenly downloaded a bunch of files. Mahjong.exe, Bubble_Hit_brch.exe, 7-superfoods-to-boost-your-immunity.pdf, etc. Small files, less than 1MB per file. There were about a dozen files in her downloads folder, a few of which had "-1" after it so it had downloaded some of them twice now.
I've Googled the filenames, Google "downloading files at random", "downloading unwanted files", etc., etc. I installed three different virus scanners and they found nothing. I believe her when she says she doesn't download anything or install anything.

There are a lot of language which compiles into Java class files when can run on JVM (e.g. JRuby, Scala, Rhino). Can you please tell me if I can take those class files (compiles by the JRuby/Scala/Rhion compiler) and run it on Android platform?

I'm making use of an API on the internet that is marshalling objects to XML files. Given that the XSD files are also available I'd like to be able to unmarshall them back in to Java objects once I've downloaded the files.After looking around it looks like JAXB is the default library for doing this in Java, but as I'm developing a mobile app the extra 8.6MB dependency just isn't acceptable. I also found XStream, but it still weighs in at 7.9MB.Poking around the Android SDK it looks like the only real XML parser available is SAX.

Any tips on how to download mp3 files? When I click on links in the browser the file just starts streaming in the media player. I saw another poster mentioned an app called "download crutch" but it isn't available in Market for the Cliq.

I have an interesting problem. I pull down an android project from cvs, which works fine. Once Eclipse builds the project, my .java files are removed. XML files, pngs, everything else is fine. I seem to be left with just the package tree, but no source files. Any thoughts?

I want to access files in the /sys, to be exact in the /sys/class folder. I just need to read some values there. I tried the Context.openFileInput method, but got only exceptions and I understand this is not the right way.

I'm writing an Android application. One problem is your app cannot contain a file whose uncompressed size is bigger than about 1Mb. I have a serialized object that I want to load that totals about 2Mb. My plan was to split this file into two smaller files, then load the object by combining both files at runtime.
However, I cannot work out how to use e.g. InputStream and ObjectInputStream to specify that I want to read the data from two input streams. How can I do this?
For example, say my object was split between file O1 and O2. How can I say "Load the object by reading the data from O1 then from O2"?

Just have a quick question: whenever I download zip files from all....droid(specially the theme files etc) using dolphin browser it asks me to save as "file.php". I usually download it on to my computer and unzip it prior to moving it to my sd card.Tried renaming the .php file to .zip once its downloaded onto the sd card. Problem is that trying to access it gives me an error message. When I do it from a PC it works fine though.

i am updating an app i developed so that it downloads xml files it needs for content management. the files download successfully to the emulator but are not placed in the /files directory that openFileInput() is attempting to read from. i am admittedly unsure as to the proper overall solution here - app originally used packaged XML and was fed to an XMLPullParser - but i cant even get as far as attempting to parse new XML at present because my app cant find the new file sitting in /data/data/[myApp]/ and not /data/data/ [myApp]/files and i cant figure out how to get it in there. the download doesnt work at all if i add that folder to path.e.

I've been left without a computer after my laptop was stolen from my car but luckily I had uploaded my important work documents, presentations, music and home movies onto my premium rapid share account by compressing them into large .rar files. Now I'm trying to retrieve some of those files with the only Internet device I have and that's my sprint hero. Been trying since last night to download a couple of them through numerous browsers onto the sd card but either the download never starts or it it gets part way there and fails. Anyone have any solutions for this or maybe a download app like Down loader for iPhone? Been searching google and these forums for help.

I'm using the Android Development Toolkit (ADT) in Eclipse Galileo. I've created a project in which to develop some util classes, which I intend to use in several upcoming Android projects. However, when I come to use these util classes (deployed as a jar and included in the Android project as a user library), I get a java.lang.VerifyError during the startup of the emulator. Can I force the verification of these library files, or do I need to include them as part of the Android project, and not as an external jar?

I am making an app for Android, in my Activity I need to load an array of about 10000 strings. Loading it from database was slow, so I decided to put it directly into one .java file (as a private field). I have about 20 of these classes containing string arrays and my question is, are all the classes loaded into memory after my application is started? If so the Activity in which I need these strings would be loaded quickly, but the application as a whole would have a slow start...
Is there other way, how to very quickly load an 10000 string array from a file?
UPDATE:
Why I need these strings? My Android app allows you to find "journeys" in Prague's public transit - you choose departure stop, arrival stop and it finds your journey (have a look here). My app has a suggestions feature - you enter leter "c" as your departure stop and a suggestions ListView appears with stops starting with "c". For these suggestions I need the strings. Fetching the suggestions from database is slow (about 400ms on G1).

Does this piece of crap not have the option to download .doc or .docx attachments? With my Incredible I can click the attachment and it downloads it automatically. This thing tries to open it instead of download it. Any thoughts on this?

Are there any apps out there that take the movie file and apply the right codec to it so that the file can be downloaded in 720p? Is this something HTC is planning on updating or did they do it intentionally for some reason? Can I upload files to youtube from my phone in 480p?

I have a problem with downloading files from hosting sites such as rapidgator, hellshare etc. On default browser and on Google Chrome files aren't downloading at all or there is downloaded a file which has for example 26kb or so, while I am trying to download files about 400-700mb. On Opera Mobile the files are downloading, but if I will minimize the browser and start any other app, the downloading process is stopped. I am really surprised with that because a few months ago I also had HTC Desire Z and I could've download any file with the stock browser and. while downloading, check any app I wanted.
I have Asus Transformer Pad 300 with Android ICS (newest update). When I download files about 10mb everything is ok, so I assume it's the size problem or maybe file extension, but I tried the app called All files download (or something like that) which has been recommended in a similar post (but that user had SGS3) and it didn't worked either.

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> }}}

Since 2.2 I have been unable to download anything and only get an error message after it takes you to the download screen. This is happening on the stock browser as well as skyfire. Am I missing something? This worked fine in 2.1.

I'm in the middle of writing an Android app, and would like to give my users the ability to share the document files it creates. What I'd ideally like to see would be files hosted on a HTTP server somewhere, so a user can simply fire up their browser on the Android phone, surf to the relevant page, and then download the file to their phone. I'd then like for my app to be able to open that downloaded file. I'm not sure if that's possible at all, but would certainly be interested in hearing from anyone that knows anything about such things. Unfortunately I seem to be having difficulty coming up with the answers myself - like much of the rest of the Android SDK, there is a severe shortage of relevant documentation.

I want to add some function to my system music player app. So I decompiled the classes.dex with dex2jar, copied the source code and add the code for my functions. Now my problem is that I do not know how to recompile the app. I can't compile it with Eclipse because it uses some system namespaces (in Eclipse it is an error so I can't compile) How can I recompile the app? I only have the *.java files.
Or can't I use the java files and have to edit the smali files? Of course that's much harder...

I spent 1 month coding an android app, and then I lost the source code in an hdd crash. Well, those things sux, but hopefully I managed to find an old apk build of this app. I was able to recover part of the source code by extracting the classes.dex file, decrypting it with dex2jar, and then opening the decrypted file with java decompiler (jd-gui.exe)... I remained amazed when I saw that my source code was so easy to found...
Now I wonder, why people use smali to reverse apk files instead of dex2jar+jd-gui ??

I've got some photos stuck in an MMS that I tried to download before I realised that I didnt have the correct MMS APN settings in (due to swapping to the Modaco ROM). The correct settings are now in but the MMS is stuck at "downloading" status. Is there any way I can rescue it, there is no forward option and I've successfully sent and recieved MMS since.
