Mar 1, 2009As is mentioned above,What i'm trying is to protect a sub- thread,and keep it going on as long as the App that starts it is still alive.In other words,If the system need more resources,Let it kill both the App main thread and the sub-thread started from it,Instead of just kill the sub-thread.Is there any way i can do this ?? And another question here,The android system seems to be "rude",As it killed my thread without telling me,even in the logs,Is this the case?

May 25, 2010My question is : on the HTC Desire, is it possible to listen music with the default player, while doing something else like browsing the web? Because when I'm under the music player app, listening to something, and then I click (or long-click) "home" button, the sound stops. Also, while i'm listening to a track, if a phone call comes in, the music is paused, but when the call ends, the track position is lost and it starts from the beginning. Is all this normal?
View 8 Replies View RelatedAndroid :: Using ASE And Playing Sound
Oct 26, 2009I have a python application (anki) running under ASE. It is a simple web server that uses the browser as a UI. My only issues are playing sound, which are stored locally. On the iphone, anki uses a command line app (play) to play the mp3 files. Unfortunately, there is no command line app that I can call that takes a filename as an arg and plays it. What are my options with android?
- write a sound service that sits and listens for a filename to play; possibly listening on a port for filename
- write an Java-app that I call from within python that forks off and loads a specified file, plays it and then exits. Can you call other java apps from ASE?
- wait till the browser supports the <audio> tag. I guess this is html5, but am unaware if this will be on android any time soon.

View 1 Replies View RelatedAndroid :: Modifying Adapter Content From Background Thread
Sep 14, 2010I've read up quite a bit on the exception thrown while using BaseAdapter, but i can't seem to find an alternative solution: Make sure the content of your adapter is not modified from a background thread. What i want to achieve is to keep a copy of a message queue in memory, and use this message queue to populate the BaseAdapter for my ListView. The reason im doing this is that the message queue will keep getting messages from a socket even when the ListView is not currently present (for example a chat window).
The problem comes when i have the Activity with the ListView in foreground, BaseAdapter binded to the message queue's data, and a message comes in the socket. Adding the new message into the queue will throw the exception mentioned above. Unless i pre-populate my BaseAdapter with the message queue (as in the BaseAdapter having its own message queue) and updating both of them when a new message come in, i can't really find a way around this issue. I don't really want to double up the effort on keeping those 2 queues up-to-date like this, surely there is a better way of doing this? Send broadcasts around doesn't work either because of the potential delay in the adapter serving a scroll and the notifyDataSetChanged call is made.
Android : Background Visualizations While Playing Music?
Oct 5, 2010So most of us know we can play a slideshow while listening to music, but how about something like Windows can do with visualizations. I'm looking for an app or something possibly "sound activated" that will show a cool background while listening to music (sort of like Windows does). The active wallpaper's are sort of on track, but not exactly what I'm looking for. The closest thing I found so far was the glow stick that changes colors...any other ideads?

Android :: Game Doesn't Work Due To Thread Background Processes
Mar 8, 2010I have written a very simple game with some simple animations, but I've noticed that when the phone checks email, or several other apps are running, the animations that update in my thread start behaving slowly or choppy. This is a problem as the game mechanic requires some careful timing of your screen touches based on the animations. So if it starts behaving erratically, the game doesn't really work well - and isn't much fun.
Is there a way to prevent this? Can my threads have a higher priority when they need to run?
Android :: Run Query On Background Thread On Cursoradapter Doesn't Get Called?
Jul 25, 2010I have a listactivity as a startup screen in my application. Which is displaying database records using custom cursor adapter. On create I set the filterable flag - getListView().setTextFilterEnabled(true)
My cursoradapter overrides runQueryOnBackgroundThread which runs corresponding query. The problem is that after typing some text and hitting enter, runQueryOnBackgroundThread never gets called. However, when the item click in the same view launches another activity(detail view of the record) and I come back to the original list activity, hitting back button, then text filtering works just fine. I don't call setTextFilterEnabled anywhere except during the initialization process and I can't really find any other API affecting this behavior, so any guesses why text filtering doesn't work initially, but all of the sudden starts working when I come back to the list activity from child activity?

View 1 Replies View RelatedAndroid :: ASync Task Progress Dialog Not Showing Until Background Thread Finishes
Apr 24, 2010I've got an Android activity which grabs an RSS feed from a URL, and uses the SAX parser to stick each item from the XML into an array. This all works fine but, as expected, takes a bit of time, so I want to use AsyncActivity to do it in the background. The line items = parser.getItems() works fine - items being the arraylist containing each item from the XML. The problem I'm facing is that on starting the activity, the ProgressDialog which i create in onPreExecute() isn't displayed until after the doInBackground() method has finished. i.e. I get a black screen, a long pause, then a completely populated list with the items in. Why is this happening? Why isn't the UI drawing, the ProgressDialog showing, the parser getting the items and incrementally adding them to the list, then the ProgressDialog dismissing?
View 3 Replies View RelatedAndroid :: Bad Sound Quality When Recording / Playing Audio Files
Oct 16, 2010Hey, I have a problem with android programing when I try to record and then play the file that was just recored. I can both record and play the sound but the quality stinks. Its not just bad is really hard to listen to and sound abit like its a computer generated voice. I use the andriod SDK-emulator. The code that sets up the recording looks like this;
MediaRecorder recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.RAW_AMR);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(path);
recorder.prepare();
recorder.start();
And the code playing the file later looks like this;
MediaPlayer mp = new MediaPlayer(); mp.reset();
mp.setDataSource(path); mp.prepare(); mp.start();
I don't know what part that makes the audio file sound really bad or if its just the emulator that makes it bad and that it would work on a real phone.
Android :: Playing Short Audio Clip Has Tick Sound
Dec 14, 2009I'm using the SoundPool to play a series of small audio clips and am having issues with the audio when it starts. I have the audio attached to a button press. When I press the button mulitple times the tick persists. I was wondering if this was the audio file itself or is there something I need to do differently with the SoundPool other than play simply play the clip. These are .ogg files I created using Audacity. When I play them in my dekstop media player, they sound fine.
View 2 Replies View RelatedAndroid :: How To Handle Screen Orientation Change / When Progress Dialog And Background Thread Active?
Jul 10, 2009My program does some network activity in a background thread. Before starting, it pops up a progress dialog. The dialog is dismissed on the handler.This all works fine, except when screen orientation changes while the dialog is up (and the background thread is going). At this point the app either crashes, or deadlocks, or gets into a weird stage where the app does not work at all until all the threads have been killed.How can I handle the screen orientation change gracefully?

Jan 9, 2010I am facing a problem with a stopping thread which is in a synchronized block. I am using TCP socket. The problem is that I am waiting on a DataInputStream object and I want to create a new socket again but it doesn't allow me to do because of the synchronized block.
I have tried with Thread.interrupted(). I cannot avoid the synchronized block. Is there any other way to do the same?
dis = new DataInputStream(ReadWriteData.kkSocket.getInputStream());
int i = -1;
String aval = ""; //new String();
char c = (char)dis.read();
It is getting blocked on dis.read().
What I should do for escaping the dis.read when I want to create a new socket?
General :: Android YouTube Apps Stops Playing Music If Screen Is Off Or Going To Background
Mar 17, 2013When playing music with the stock Music Player application on my phone and turning the phone screen off or multitasking, the music is still able to play in the background. Is it possible to do the same with the stock YouTube app? I want to let the audio of the YouTube video I am watching to keep playing when I either exit out of the app or when I press the power button on my phone to turn off the screen to save battery. Although I can just set my phone screen to not go off when idle for a certain amount of time, but then again, that is battery consuming.
