Android :: How To Stream Data And Resources From Website
Sep 12, 2010
how do you stream certain bits of information from a website. From what I understand webview launches a web page, but what if I want to only stream a paragraph that was published on a site. Example: Yahoo! Fantasy Football. Updates on players and the news feed about them.This is obviously a lot more complicated than my question. I would be interested in a tutorial that could walk me through this. Does this also take programming on the server side to send this out?

I'm looking for some resources (online is good so I don't have to buy books, but books are ok) about mobile website development. I'm specifically targeting (in order) iPhone, Android, Blackberry. I'm proficient in HTML, and am getting into HTML5. I want to learn more about it in general, but specifically about using geolocation, detecting phone types, optimizing css, and a few other topics. Does anyone have suggestions on where to look?

I was tried for RTSP stream for a long time, finally I could success to play the RTSP stream from mobile Youtube website:
http://m.youtube.com/
My approach is to copy the stream link and paste it in my code, then, there are sometimes success to work(play) on Android and sometimes will not. I can't figure out why? Is something wrong about Youtube server? Because my code is just the same, and only change is the stream link URL. I used VideoView widget and my Android platform is sdk 1.5 and under x86-based, so I really want to know why and how can I solved for this. This is the logcat when I can't work for the video stream.

Is there an app or website that lets you download or stream video clips (movie trailers, etc.) in 720p?
I tried youtube and selected "view in high quality" but I highly doubt it was displaying 720p.

I've seen some examples on how to parse XML data but they are all based on if statements and that's a lot of hard coding is there a more genertic way to do this?

I was wondering what the best approach is on Android to retrieve information from a HTML page hosted on the internet? For example I'd like to be able to get the text from the following page at the start of each day:http://www.met.ie/ forecasts /sea-area.asp I have been downloading and parsing XML files but I have never tried to parse information from a HTML type file before.Is there a native way to parse the information I want?Or do I need a third party library?Or do I need to look into screen scraping?

I am new to Android development and am interested in working out a design of an application. I am however, unfamiliar with the best way to handle what I want to do. I am interested in obtaining information from my band's Joomla website and placing it into an Android application. At the moment I'd like to get News articles posted and potentially other information that I create on the site. I was thinking of doing this by setting up RSS feeds for the website. Would it be better to somehow access the data directly by connecting to the database? I don't know PHP so I can't develop a webservice to access the content. Any ideas?

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.

I am new to android programming and have a strong keen interest to learn it. I want to write a program that fetches the data from a website, segregates it and displays it on the screen of the phone. The data could be grocery list from a supermarket or sale items in a mall. Could you please suggest as to how I can go ahead and start this.

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'm using this kind of code for my TCP/IP connection:
sock = new Socket(host, port);
sock.setKeepAlive(true);
din = new DataInputStream(sock.getInputStream());
dout = new DataOutputStream(sock.getOutputStream());
Then, in separate thread I'm checking din.available() bytes to see if there are some incoming packets to read. The problem is, that if a packet bigger than 2048 bytes arrives, the din.available() returns 2048 anyway. Just like there was a 2048 internal buffer. I can't read those 2048 bytes when I know it's not the full packet my application is waiting for. If I don't read it however - it'll all stuck at 2048 bytes and never receive more. Can I enlarge the buffer size of DataInputStream somehow? Socket receive buffer is 16384 as returned by sock.getReceiveBufferSize() so it's not the socket limiting me to 2048 bytes. If there is no way to increase the DataInputStream buffer size - I guess the only way is to declare my own buffer and read everything from DataInputStream to that buffer?

Does Android MediaPlayer can only work with file sources? I would like play media (video) from a network stream, but the stream comes in a non-standard protocol, so I have to somehow feed Android MediaPlayer with the data only. Is there anyway to do that? I found a few web pages suggesting using a temporary file for the buffered media data etc. but I would like to minimize the I/O usage as much as I can, so I'm looking for a API only solution if there is any? how about JNI? but looks like the permissions going to be an issue with that also.

These days I try and try to send data(stream) from an Android-Mobile to a PC VIA USB cable,
I made it good that a socket("10.0.2.2", 6543) on the android emulator sending data stream to a ServerSocket(6543) On a PC , before which I had run "adb forward tcp:12345 tcp:6543".
But when I setup a socket("10.0.2.2", 6543) on a REAL Android-Mobile and a serverSocket on the PC, the socket on the Android-Mobile can NOT send data to the ServerSocket on the PC.
Why can't I use the socket on the Android-Mobile to send data to the ServerSocket(6543) on the PC. What is the different between the REAL device and the android emulator. Or , is the IP setted to be wrong? How can I get the IP of the PC VIA USB ADB?
On the other hand, I make it out to send data from a PC to a REAL Android-Mobile as socket and serverSocket.

Got my phone a couple weeks ago and absolutely love it! Problem is I'm playing with it too much and already got a text saying I am at 65% of my data usage plan well before the billing cycle will be complete. How can I turn off completely/minimize the data stream? So far I've done (Home> All programs Tab> Wireless & networks and uncheck the box for Mobile Networks) and (Settings> Accounts and Sync> Background data "Applications can sync, send, and receive data at any time"). I wanna just be able to use it at WiFi spots so I don't accrue any fees.

In my Android project, I want to loop through the entire collection of Drawable resources. Normally, you can only retrieve a specific resource via its ID using something like:
InputStream is = Resources.getSystem().openRawResource(resourceId)
However, I want to get all Drawable resources where I won't know their ID's beforehand. Is there a collection I can loop through or perhaps a way to get the list of resource ID's given the resources in my project?
Or, is there a way for me in Java to extract all property values from the R.drawable static class?

I've set my Friendstream to update every hour, and this was working fine for weeks. Recently, although it's still refreshing the sync time icon at the bottom every hour, it's not actually updating the widget with the new information. It takes a manual sync for it to refresh. Auto-sync is on, background data is enabled.

I currently have a few classes that are called by an activity (some statically) in which I want to use a string resource. I tried: Resources.getSystem().getString(R.string.mystring), but am getting an error. It seems as though you can only use this within an activity.
Is there anyway to use a project resource in a standard (non Activity) class without having to pass the resource object from the activity calling the class?

I have an app with 2 Activities and an IntentService all which need to access the same SQLite Database table. What's an appropriate pattern to use?
Should I create a ContentProvider that manages access to the database, ie opening/closing, querying, updating etc. And have the 3 clients all access the DB via the ContentProvider?
Or is it OK for each client to access the DB directly? This is the approach I have now and it seems to be working, but I need to close my cursor and the DB after executing every statement or I start generating stacktraces in the log about unclosed DB resources. But closing the DB after each statement seems wasteful and I suspect that this approach will always be susceptible to the stacktraces because there is always the potential for collisions between either of the Activities and the IntentService.
I haven't been able to find any good resources that show DB usage in full. It always snippets that miss out the *obvious* piece such as when should the resources be closed etc.
