Android :: Want To Write A Little UPnP - Discover Application In Phone?
Feb 7, 2010
I am very new to android. The Eclipse and the Emulator is running and I have bought an device already. I want to write a little UPnP- Discover-Application first. I used CyberLinkForJava under Java some years ago. I read on this list (2010/1/29) that this framework can be used under android too. Like mentioned in the post from skonno I downloaded the code via svn from sourceforge and copied the trunk/cyberlink/upnp-stack/src/main/ java section into the source folder of my android project. Then I`d got errors in XercesParse.java and kXML2Parser.java. If I delete this classes it runs without errors. But the code from the cyberlink documentation. Code...

How does one go about listing the resources that are available in an application?
For example, I would want to find the names of all files under /res/ xml.
Reflection on the R class didn't seem to work since the identifiers are static constants. R.xml.class.getDeclaredFields() doesn't return any fields.
The AssetManager didn't seem to work either because these are not raw assets.
Does anyone have ideas or examples?

how I can find the memory used on my Android application, programmatically. I hope there is a way to do it. Plus I would like to understand how to get the free memory of the phone too.

Writing an application to invoke the camera can be done but I want to write an application to hold on to the camera resources. Meaning while this application is running, camera cannot be accessed by other applications. Is this possible? The aim is as long as the application is running camera cannot be used.

For a semester project, I had the idea to implement Windows 7's Play to infrastructure to either use a phone as the end point (the player) or to stream stuff from the phone to a Windows 7 machine. Does anybody have experience working with this API? Is this do able over a couple of weeks (prototype, just proof of concept, not end-user ready) or is it too much for a project of this scope? Note: I'm not looking for code samples, just an assessment of the feasibility of this project. If you have any documentation from MS or otherwise that would be awesome although not the crux of the question.
I discovered that the Windows 7 Play-to functionality is based on DLNA and any device supporting DLNA (I think) can be used as a destination for the Play-To context menu. However, I'm having a really difficult time finding any sort of documentation on DLNA. I'm wondering if you need to be a member of the DNLA to actually get access to the spec? Alternatively, I know DLNA is built on UPnP, it wouldn't exactly do what I want, but it would be a step in the right direction, so, to revise my question does anybody know of any open-source C/C++ or Java (preferable) libraries that would help me implement UPnP or DLNA?

I have an application that can read and write txt files to the phones sdcard. By using this code for reading files:
@Override protected void onListItemClick(ListView l, View v, int position, long id) { super.onListItemClick(l, v, position, id); mFileNameOpen = files.get(position);
String st = null; mVector.clear();
notepad.mNewEmpty = false; try { File f = new File(Environment.getExternalStorageDirectory()+"/ notepad/"+mFileNameOpen); FileInputStream fileIS = new FileInputStream(f);
BufferedReader in = new BufferedReader(new InputStreamReader(fileIS));
do { st = in.readLine();
mVector.add(st);
}while(st!=null); in.close(); ...
} catch (FileNotFoundException e) { e.printStackTrace();
} catch (IOException e) e.printStackTrace();
and this to write them:
try { File root = Environment.getExternalStorageDirectory();
File fileCheck = new File(root, "/notepad/" + fileNameSave + saveExtension);
boolean exists = fileCheck.exists();
if (!exists) { if (root.canWrite()) { File textFile = new File(root, "/notepad/" + fileNameSave + saveExtension);
FileWriter textWriter = new FileWriter(textFile);
BufferedWriter out = new BufferedWriter(textWriter);
out.write(SAVEAS); out.close(); written = true;
} else { written = false; else { written = true; showMaybe = 1; showDialog(DIALOG_SAVE_EXISTS);
catch (IOException e) {Log.v(getString(R.string.app_name), e.getMessage());
This has been working fine on my Tattoo and all the emulators I've tried this on. But it does not seem to be working on moto droid. Is there something different to consider with moto droid? Or have I missed something in the manifest maybe?

I need something along the lines of ipad's keynote + airplay so that powerpoint presentations with notes can be stored and displayed via upnp/dlna from my tablet on our presentation screen...I don't always have time to load the powerpoints to the PC and make the small format changes that always seem to be required when you copy a ppt file to another computer and since the pc has both xbmc and windows media center and the screen has a apple TV something should be doable. If this already exist..I have been wearing out search xda and Google. I need to see thumbnails of my slides and see my notes on the tablet and wireless display my slides on the screen.

I have two published apps that are pretty targeted to the user collecting their personal medical data (like Blood Pressure, etc.) and then, eventually sending it somewhere, if they choose.
I decided to put Read/Write permission on my ContentProvider, so if another app comes along that wants to the access that content, the user will be warned. The permission that is required is declared in my apps.
When the user installs my apps, they are also given a warning that the app requires that permission (even though it's the one that declares it), and it shows up in the Marketplace also.
The question is: Is it possible that the permission acceptance part of installing my app could be putting customers off? I don't know what other's acceptance rate is, but mine is around 50% of customers who download it have active installs.

How can I write a Broadcast Receiver that will be invoked when user clicks on any application icon?
I tried by writing:
CODE:...................
But it is not called.
I tried, by using Packagemanager I will get ApplicationInfo. From that I can know all the application starting activity name and package names. I thought I can use them to registerReceiver and my receiver will listen by its launching activity and package name.

I am currently doing my Bachelor Project concerning Android Programming.
Therefore i need a possibility to SCAN/DISCOVER Hot-Spots or WLAN's where i can connect to.
In many topics i have read, that the EMULATOR does NOT support WiFi scan with WiFiManager. I also tried using ConnectivityManager or BroadcastReceiver. But it doesn't ever work.
So my question ist the following - is it CORRECT that the emulator does not support any kind of WLAN Scan/Discovery? I need as many comments on this as possible - because only if its REALLY true, that the emulator does not provide WIFI functioanlity, then i can ask for buying a Dev Phone.
And if so, WHY there is no WiFi support within the emulator...?

BackGround: There are Facebook APIs(and SDKs) available to develop applications for other Mobile devices like iPhone, BlackBerry etc, but it seems there are no official ones for Android(?).
People have ported Java APIs to work on Android and have written FaceBook Client applications(FaceBook dev: Wiki Page). Apparently, there is also a light weight FaceBook SDK in alpha release for Android(a la FBRocket). But it is not avised to be used in Production.
Since these FaceBook functionalities have been exposed as REST based service, most of work would invove sending requests in desired format over Http. So, writing a FaceBook client app for Android certainly is doable.There are similar applications already in market e.g.: Bloo.
Questions: When asked to write a FaceBook client application what approach should one undertake? Should we choose the SDK or invoke the services over Http?
If there is already a Web application that integrates with FaceBook, can we just browse to that Application from inside a WebView and be done with this?

I have never had trouble rooting/unlocking android phones until I got a Samsung Galaxy Discover SGH-730M. I can't figure out how to root it. Unlock root pro did not work, and neither does using the ADB (I get a mounting error).

All of today my Samsung Galaxy Discover wouldn't turn on. Nothing. Black screen, no lights, no sounds, no vibrations - nothing. I left it all of today to see if it would get any better, but it didn't, so I took the battery out and put it back in. Now it keeps rebooting itself over and over again, and every time it boots to "Android System Recovery <3e>". I've tried a few of the options but nothing is working, it just keeps booting over and over again to that screen. How do I get it to boot to my actual phone, normally?

I have a Samsung Galaxy Discover. I want to be able to put my game apps, music, and photos on my SD card. I also want to have the game apps, music, and photos on my laptop without having to move the SD card around. I have changed the storage location when I take pictures to the SD card. I want to be able to put pictures I receive in text messages on there as well. I have tried manage apps, I have tried connecting my device through USB to my laptop and manually copying the files to the SD card. Are these goals possible? How can I accomplish them?
