Android :: Updating Media List When Thread Complete
Feb 22, 2009
I am developing an application on the Android Platform for my music service (axcid.org). Haven't spent a huge amount of time in Java but could use a bit of help with this code: http://pastebin.com/m5300a4e6
Bit of bad practice in there I know but I haven't spent a ton of time developing Java apps. Anyways the problem:
if (!this.listLoaded) { //holdup this needs it's own thread
//Url load and parse time. // Now we can start a thread for the search
Thread thread = new Thread(this); thread.start();
I need update media list to be called when:
public void run() { // search
String URL = this.getIntent().getExtras().getString("searchurl");
sm.LoadResults(URL+"?android=1"); listLoaded = true; }
is done. However calling it from the thread will crash Android. Did many google searches but found nothing. How can I call updateMediaList when the thread is complete? (from the UI thread)

I want to translate my app into all available markets. code...
However, look at http://developer.android.com/reference/java/util/Locale.html
it lacks : polish pl_PL and nl_NL
Now what I'm doing is creating values-fr values-es directories. But my phone only has English and Spanish locales.
Here's two things that would help:
1. A definitive list of all locale suffixes that are allowable as the values-?? directory names 2. A way to add more locales to my phone.

I am trying to write an application with a list of items read in from a file. This item list and the fields that go with each item are fed into a DB. The item names are presented to the user as an auto- completing list. Once the list item is selected, I would like to get the value from the list and use it to query the database and display all the detail information.
The problem I am having is trapping the event using onItemSelectedListener and onItemSelected.
Below is what I am trying.
CODE:..............
This doesn't compile, but it has the fewest syntax errors.
How to get an OnItemSelectedListener to work? and how I grab the value selected?

I recently got the G1 and used my Gmail account online (via computer) to setup my contact list and then sync it to my G1. Now when I compose an SMS message, and begin typing the name of the person in my contact list, only some of the names that match will appear in the drop down auto-complete list but others that match don't show up at all. To compose SMS to them I have to use the Contacts>Scroll to contact>Select text to mobile method. Any ideas why some of the contacts do not show up in the auto-complete list when composing an SMS and typing in a partial name in the To field?

Is there a list anywhere of what apps are on the unrooted phones?
If some one could run
adb shell
cd /system/app
ls
or something..
I (like a noob) uninstalled some of the bloatware apps from a list of safe to remove apps and now I have a fear of messing things up when froyo comes out.

I am programming a game with fast graphics. The MediaPlayer is stuttering sometimes. When I have the MediaPlayer in a service, it does not stutter, but some people here adviced me not to use services if they should stop automatically when the user ends my application. So how can I set the thread-priority of the MediaPlayer-Object? SoundPool uses the MediaPlayer and with SoundPool, you can set the thread-priority, but I cannot add my audio-file to SoundPool, because its size is about 2mb (too big for SoundPool). I can lower my main-thread-priority so that the MediaPlayer has a relatively higher priority, but isn't this a bad idea?

When the user clicks a button, the listview is supposed to add another value to the list and show it. When I press the button nothing happens.
MatchesList.java

I'm an experienced C++/Java dev who has been truly enjoying that past two days of getting neck deep into the Android SDK. I can foresee a lot of sleepless nights ahead Now, being arrogant due to experience (lol) I basically wrote a hello world Activity, got it to work and promptly decided to write an out of process service with accompanying client for project #2. Android is so well thought out (if not exactly documented although that's an 'over time' issue inmho) that I had basically implented everything but callbacks into the client before realizing (and feeling like a total idiot) that there's a very nice example called RemoteService (lol @ me - again) Basically, this validated everything I'd been doing, although I did notice that because my client is in its own project and namespace and my service is in another project and namespace (but the same Eclipse workspace) that I had to have the service entry in my service's manifest AND my client's manifest (that one took me a while to figure out) in order to bind on the service. Anyhow, everything's great, I am starting to love on Android (figuratively) but I've run into <BRITISH-NESS>a bit of a sticky wicket, eh, wot?</BRITISH-NESS>.
When my client Activity binds on my service (which is running in its own process) and calls the equivalent of 'registerCallback', the interface is added perfectly to the RemoteCallbackList object and I can immediately (right on the next line of code) use the interface to send a notification to the client. Now, my problem is that when my main service thread tries to pull the interface out of the RemoteCallbackList via the broadcast methods, the RemoteCallbackList is always 'empty' - it returns 0 from beginBroadcast. After double checking ensure that I AM actually adding it to the list (because I've been a collossal idiot before) and that I am getting success back from 'register', I immediately think it's a threading issue, so: I add logging code to the service in key places to log what the thread id is repeatedly, and I think "uh, I think I need to use a handler of some sort to make the call back in the thread that handled the registration" and to double check I call beginBroadcast right after 'register' and find that it always returns back the correct number of callback interfaces. So it VERY much appears to be a threading issue (to me) so now I'm a bit stuck I've written a handler so that my main service thread can request the correct thread to actually call 'beginBroadcast' and then thought 'how is it going to know what thread that is...?' and instead am now thinking I need to pass, via a handler or something, the incoming interface from the thread that runs when the client calls the equivalent of 'registerCallback' to my main service thread. What part of the proper paradigm am I missing? BTW, as an example of the thread IDs, my main service thread is #1, the runnable I use for tasks in the main service thread shows an ID of #1, the message handler I was thinking I could use, shows an ID of #1, but the thread ID I get in my code in the service that runs when the user registers their callback is #7.
If I plan to notify clients when the service notices something it thinks they need to know, do I need to notify (somehow) the clients via the thread with ID #7 or do I need to pass the interface I get when the user registers their callback from thread #7 to thread #1 and call 'register' on the RemoteCallbackList from thread #1? Sorry for the verbosity but I figured more is better than less. Again, everything works great except this one little part.

Has anyone else noticed that the built in Music player for the Incredible updates MP3 album art automatically? If so, does anyone know how to turn it off? I am meticulous about keeping my collection organized and I do not want the player updating any of the tag info. I definitely do not want it going out to the net to download art.

Does anyone else suffer from slow scrolling? For instance on the list of applications and on a large message thread the scrolling is very laggy and jerky. Surely this shouldn't happen with it's 1Ghz processor?

I'd found a way to see all of my text messages which had a "failed" status on them, and I was able to delete them from that list. But now I'm looking at my phone and for the life of me, I cannot figure out how to do it!
Basically, for one of my texting threads, there's a red triangle with an exclamation point icon, next to the paperclip icon for that thread. I'd really just like to know if there's a way to find the text responsible for this error so that the icon doesn't show up next to the contact's name anymore? I'm using an LG Lucid with Android version 4.0.4, and my guess is that probably since that update whatever option I'd used to find the failed texts has either moved or was taken out.

I push a audio file named "music.aac" into SD card, and then execute "Media Scanner" application or re-start the device. I found that media scanner didn't process ".aac" file, so the "music.aac" file doesn't exist in music player. But Android supports AAC/AAC+/eAAC format.So who know the reason that the ".aac" file doesn't be processed by media scanner.

I am writing an application in which i need to handle messages between the main thread(the deafult UI related thread) and the user created Gamethread.
The requirement is like this.
An activity(say "Activity_X") is setting the view by "setContentView(some "View_Y")". In "Activity_X" i have implemeted "onCreateOptionsMenu()" and "onOptionsItemSelected()" fucntions for creating menus & a switch case for action to be taken on selecting those menus.Menu has items like "resume/pause/zoom/" .
All action to be take on selecting these menus are implemented in "View_Y" in a separate Gamethread by extending "Thread" class.
So whenever a menu is selected in "Activity_X" i need to send a message to "View_Y". And on receiving this ,a particular action/method should be called in View_Y(GameThread).
How can i achieve this using Handlers?Is there any other way of doing this? Please do share with me some code snippets for these.

I want to do the drawing in another thread to speed up the game(it is way to slow right now). I was told to do this but don't quite understand why that would speed things up. Is it GameView that should implement Runnable? Should I make the thread sleep when not drawing? where should I start the thread? package com.android.WWS;
import android.app.Activity; import android.content.Context; import android.graphics.*; import android.os.Bundle; import android.view.SurfaceView; import android.view.KeyEvent; import android.view.View; import android.view.View.OnKeyListener; import java.lang.Runnable; import java.lang.Thread;...................

Used MML to sync my Itunes to the droid. was relatively easy. it didn't like purchased songs so i just deleted them from MML. Then in the all song list it randomly doubled up songs. But the worst thing it did was there a quite a few songs where it mixed up the song title with a different song.

Anyone having trouble with widgets stop updating? Like my clock/calendar/weather/news/pretty much any widget i have stops updating after an hour. So i look at my clock widget two hours later and it is an hour behind. Happens to ALL my widgets.Even the quick turn on/off wifi,bt,gps and such. They just stop updating/showing animation.I have ADW launcher installed. I am wondering if it is that. I do not really want to remove it as i hate the stock 3 button interface at the bottom (why do i need a contacts and phone, just use the phone to look thru contacts, wasted space IMO) and am quite keen on keeping the 5 button.Any ideas? If i power off the phone and turn it back on it's fine again for about an hour. SOmetimes randomly thru the day it will start updating and working fine again then randomly stop again.

The Android doc says "Like activities and the other components, services run in the main thread of the application process." Is the main thread here the same thing as UI thread?
