Android :: Move Image Downloader Into A Seperate Thread On Android
Apr 5, 2010
I have the following code running on my Android device. It works great and displays my list items wonderfully. It's also clever in the fact it only downloads the data when it's needed by the ArrayAdapter. However, whilst the download of the thumbnail is occurring, the entire list stalls and you cannot scroll until it's finished downloading. Is there any way of threading this so it'll still scroll happily, maybe show a place holder for the downloading image, finish the download, and then show?
I think I just need to put my downloadImage class into it's own thread so its executed separately from the UI. But how to add this into my code is the mystery!
CODE:........................

I have an application that starts on boot using a broadcast receiver, also I have an activity and a process, because the service must run always on the background I am starting the service on it's own process using the android:process manifest tag.The ui is only for presentational needs and I would like the user to be able to run the service even if the activity is not active.when I press the back button or the home button the activity's on destroy method is called and the service although seems its running (it appears on the task manager) its not behaving as supposed, it should connect to the net and send some data but every X time using an timer task but the task never fires so the data are never send.

I have integrated the downloader activity (Google provided) into my application.. On the whole a very straight forward process. A problem I have though, is, after the downloader has completed the window disappears and nothing happens. If I hold down the HOME key I see my app and if I click on it my appss window comes up and runs correctly. Also when I run it subsequently it works correctly. Has anyone else experienced this? It certainly looks like the downloader should trigger my app when it is done; I am not sure if the window is just not getting focus or someething. It is a fullscreen GL app.

I have an extended BaseAdapter in a ListActivity: private static class RequestAdapter extends BaseAdapter{ and some handlers and runnables defined in it
CODE:.......
In the getView function of the Adapter, I'm getting the view like this:
CODE:..........
and the image is getting loaded this way:
CODE:.................
Now, the problem I'm having is that if there are more items that need to display the same picture, not all of those pictures get displayed. When you scroll up and down the list maybe you end up filling all of them.
When I tried the commented out line (holder.avatar.setImageBitmap...) the app sometimes force closes with "only the thread that created the view can request...". But only sometimes.

I'm using App Inventor to develop a small game as Mole Bash.
The tutorial I'm following shows me how to make an Image Sprite appear on random locations given a certain amount of time.
I'd like to give the Image Sprite a list of 9 coordinates where he should position the image after the given amount of time in a random way.
So, I believe it should go something like this:
Procedure - Moveto - x1 OR x2 OR x3 AND y1 OR y2 OR y3
I can't seem to get the logic command OR on this procedure, since it will only let me give a min and max number for both x and y.

I have the HTC Eris which is my own private device. I am currently synced up to my employers email server which allows me access to my work email. I would like to sync my home computer and email to this device and I don't know how to go about it. Also, if I do this, would all of my info be private or sperate from my work email? Again the Verizon account is my own plan and this is not a company provided device.
I also would like to know how to transfer photos from my phone to my desktop . Do I need an app for that or can I just sync to my desktop and transfer them directly?

I'd be interested in a separate keyboard for my incoming Verizon Droid Incredible. An actual keyboard, not one of the bitty ones that come with the Motorola Droid, for example, and that attaches through the mini-USB port on the phone.

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.

Long-time lurker here making my first post. I tried doing a search but wasn't able to find anything. Any help would be greatly appreciated.
I downloaded Android 2.2 this morning. Note: I did not attempt to sync my
"corporate" microsoft exchange calendar before today so I have no knowledge of how this may have worked on Android 2.1. I believe I read somewhere that 2.1 allowed for separate or multiple calendars.
I just set up my "Corporate Sync" account today on my stock Droid X and it merged all of my work's Calendar events (via exchange) with my Personal Gmail Calendar events into one calendar.
I'd prefer to keep these things calendars separate as it's hard enough to not think about work when I'm not at home!
I have 2 Questions:
(1) Does anyone know if there is a way to have two separate calendars (i.e. one for work, and one personal)?
(2) If I add an event to my Google Calendar will it sync to my Corporate Calendar? I'm assuming No since I don't think it does it in the opposite manner (e.g. Corporate calendar doesn't sync to Google Calendar).
Jorte also merged all my Work events and Personal events together despite the settings only stating that it will only sync my Google Calendar. So I can't use Jorte and Google to view Personal and Work calendars that way.

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;...................
