[Q] Shoutcast ICY to Http (Eclair compatible)

Hi.
I'm currently working on a wakeup-app (alarm) that plays your favorite radio-station via shoutcast-stream.
It looked really easy:
Code:
MediaPlayer mp = new MediaPlayer();
mp.setDataSource(PATH_TO_FILE);
mp.prepare();
mp.start();
Then I found out Eclair doesn't support shoutcast's ICY protocol. Grmbl.
So for 2.1 (and earlier versions) it is required to handle the shoutcast-stream seperatly and pass it to MediaPlayer via http.
I even found an example:
http://code.google.com/p/npr-android-app/source/browse/trunk/Npr/src/org/npr/android/news/StreamProxy.java
Problem is that it's all a bit too advanced for me, so I was wondering if anyone has a really simple example of how to do this?
Something like:
"Add 'this file' to your project (where 'this file' would be a class similarly to StreamProxy) and then add this to your application:"
Code:
StreamProxy sp = new StreamProxy();
sp.setDataSource( SHOUTCAST_URL );
MediaPlayer mp = new MediaPlayer();
mp.setDataSource( sp.getProxyUrl );
mp.prepare();
mp.start();
(Pardon my english

fixed!
Will post how I did it soon.
Here's the app:
http://android.rejh.nl/fmalarm

Just got reminded by someone that I never posted the solution. Here goes:
Code:
// Streamurl
String streamUrl = "[Path-to-audio-stream-or-file]";
// Prepare Proxy (for Android 2.1 en lower (sdk<8))
sdkVersion = 0;
try { sdkVersion = Integer.parseInt(Build.VERSION.SDK); } // Note: Build.VERSION.SDK is deprecated..
catch (NumberFormatException e) {}
if (sdkVersion<8) {
if (proxy==null) {
try {
proxy = new StreamProxy();
proxy.init();
proxy.start();
streamUrl = String.format("http://127.0.0.1:%d/%s", proxy.getPort(), url);
} catch(IllegalStateException e) { Log.e(LOGTAG," -> IllStateException: "+e, e); }
}
}
// Create mediaplayer and set stream (proxied if needed)
mp = new MediaPlayer();
mp.setDataSource(streamUrl);
UPDATE!! Forgot the StreamProxy code

Problem of flashlight app code (Eclipse)

Hello everyone ..
I have problem on developing a flashlight app
I tried the solutions that provided by Eclipse but none solved the problem
or even make any sense to me :angel:
every "Void" statement on the code appeared as an error
and i don't know why .. also i'm sure that everything on the code is correct
Examples of the errors:
private void playSound() {
private void toggleButtonImage() {
private void turnOffFlash() {
and .. etc , i got an error on every "Void" !
so.. i'm waiting for your opinions
Thanks in advance )​

Hi,
It is impossible for us to tell you what you have done wrong if you do not post your source code.
It could be just one character missing somewhere or one to much.
We need your code to help you.
(If you do not want to release it completely, copy your project and remove those parts you do not want us to see. This could also help you with finding the error yourself. )

these work

Does it work on other projects?
It is working for him, so I guess that the errors are not in the code but maybe your project setup or your installation of Eclipse and the Android SDK is the reason for that.
So to quote myself " Does it work on other projects?".

Oh no, there are mistakes with the brackets.
For example you set a listener somewhere inside a methods. However, you forgot to close the bracket (I mean these ones {}). So it ends with a semicolon. It wants more lines of code.
So check your brackets.

Void methods should not return anything. So you can remove all 'return' words in the void methods.

These returns ARE allowed. They are not necessary but allowed. You can stop the method by this.
It is really a problem with these brackets {}.

[APP] Android transation helper script

If your application has different language versions and a lot of changess to strings.xml (strings added, IDs renamed, strings deleted), the translations will soon become a mess and people won't know anymore what is there left to be translated or if particular string needs translation at all. To fix that I've created a simple java proggy, that
1) loads English strings as a golden source for all other strings
2) compares each values-xx/strings.xml to the above
3) adds a XML comment <!-- PLEASE TRANSLATE --> to each missing value
4) outputs modified to values-xx/strings.xml_obr, sorted by ID
Fast and easy. Here's the code (note: requires jdom-2.x.x.jar)

To run it just pass a path to your resource directory:
Code:
public class Main {
public static void main(String arg[]) {
new AndroidStringsHelper("/path/to/your/workspace/project/res");
}
}

[Q] I want to fix a bug inside APK app! (A SQLiteConnection was leake)

Dear all , How are you
I have an Android application , the Developer of it chose to stop the support for it.
Any way i want to fix the bug,
I am not that expert with Java so i am seeking for help
The error that the app return when it get data from the database is :
Code:
11-14 15:42:26.420 W/SQLiteConnectionPool(15763): A SQLiteConnection object for database '/data/data/com.bookscars.src.v65/databases/AppDbStoreroot7' was leaked! Please fix your application to end transactions in progress properly and to close the database when it is no longer needed.
Now i did decompile the APK , search for the class who call AppDbStoreroot7 database to see what we can do for it ! and i found it,
Please note that i need to edit on the Smali code
what i need to know , where i need to put the close commad since i am not a JAVA expert

Please advice where to put the close command , please note i will edit on smali !

I am sorry i don't understand. can you explain ?

I am not sure, but your class might be missing constructor
more info: http://www.javatpoint.com/constructor

For some reason it says that it needs and Empty constructor.
Type inside ChooserAppSettings class:
Code:
public ChooserAppSettings(){
}
This may fix it. I am not sure though why it needs the empty constructor. What class is your ChooserAppSettings extending or implementing??
Can you show all the logcat messages?

Linearlayout.
Tried the above but didnt worked

Try adding these:
Code:
public ChooserAppSettings(Context context){
super(context);
}
public ChooserAppSettings(Context context, AttributeSet attrs, int defStyle){
