How to use an android service to hold a server communication?

How to use an android service to hold a server communication? - Java for Android App Development

Hi,
I´m new here and hope you can help me.
I wrote a service for an android app.
The service should keep on a server communication with an TCP Server.
I have to use this kind of solution!
If I start the app, the service is called. I get an connection with the run()-Method (I checked it with an boolean).
But now I can´t receive and send any messanges between server and android device.
Here is the code, may it helps:
Activity:

If I try it only with my TCPClient Class, the connection runs. May I call a method wrong?!

[Q] help on eclipse app

Hi guys,
First of all i`m completly noob on this so don`t be much hard with me
ok. i`m trying to develop a simple app just to run 4 simple command to install another app but for now the only thing that i can get to work was asking for su permissions...
can someone help me with this?
Thks a lot
HTML:
try {
runtime.exec("su -c busybox mount -o rw,remount /system");
runtime.exec("cp /sdcard/gscript/xrecovery.sh /data/local/tmp/xrecovery.sh");
runtime.exec("chmod 777 /data/local/tmp/xrecovery.sh");
runtime.exec("/data/local/tmp/xrecovery.sh");
runtime.exec("reboot");
}
catch (IOException e) {
e.printStackTrace();

do not think anyone has the knowledge to help me: .- (
My intention is to create a simple program that installs a file which is in sh sdcard,
"sdcard / gscript / xrecovery.sh"
until now could only be granted access to the root but do not know where and what command should I put to run that sh file...
is that no one can / want help?

You should be able to execute a .sh file by using:
Code:
sh xrecovery.sh

Without sdcard path! ?
And where should i put?
Thks; )
Sent from my AOSP on Xperia (US) using XDA App

Of course you need to specify the path (it cannot guess where your script is, unless you add it to your PATH). So I guess the following should work for you:
Code:
Runtime.getRuntime().exec("sh /sdcard/gscript/xrecovery.sh");

Unfortunely i cant make this work UK sure that im putting the command Sony the wrong place. I've allready try put Sony a different pplaces but never work: (

[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

Please read this to help yourself: [GUIDE] Debugging apps
At least read this for posting your problem on XDA: http://forum.xda-developers.com/showpost.php?p=42601921&postcount=9

You cannot modify the UI/ dismiss a dialog from another thread.
Use a Handler and its post method.
However, please read the debugging thread. After reading that, you would have easily figured out what is wrong.

There should be more log code which is important. In every case there should be an Exception which is thrown.
I just found this library: http://www.aftek.com/afteklab/aftek-RTMP-library.shtml
Might be helpful.
(Both formats are not natively supported by the Android platform: http://developer.android.com/guide/appendix/media-formats.html)

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){
super(context, attrs, defStyle);
}

Issue solved.
was a stupid fault of myself xD
