I have created a activity and set a the title bar to contain a progress bar like this: this.requestWindowFeature(Window.FEATURE_PROGRESS);getWindow().setFeatureInt(Window.FEATURE_PROGRESS, 500);But it turns out to be a horizontal bar, how can I make this a spin bar? (without creating a custom title bar)

My old app was threading image loads, because there are a ton of them, however, it looks like the OpenGL implementation protects itself to a single thread. I have a basic loadBitmap() function as follows:...............

I've been stuck for ages now trying to implement threading or background image loading for a custom tile overlay class I've been working on. I'm pretty useless when it comes to Java so threading isn't something I've had any experience with. Basically I have extended an ItemizedOverlay and in the draw() method calculate the tiles I need to display over the standard google tiles then fetch those images with a URLConnection and using BitmapFactory decode them and draw them to the canvas at the correct position on the screen so that the images are on top of the google tiles with about 50% opacity (the custom tiles are cellphone network coverage png's which are used for our web app). I initially got this all working with the tiles loading in the correct places but hit issues with memory and "freezing" while panning so implemented some basic caching and memory management to only store the tiles that are displayed on the map in memory and when downloading a tile store it to SD card.
Then I figured the freezing while panning is due to the blocking nature of downloading the images so, have been trying to implement threading. I created a class that extends AsyncTask to download the images in the background and store them to SD, in the onPostExecute method I then try to draw all the tiles. But onPostExecute never seems to fire, now I know that the AsyncTask has to be called in the main ui thread so tried to debug the execution with Thread.currentThread().getId() calls through out the code. The thread Ids through out is 1 and then 10 for the doInBackground method for the AsyncTask. Now I'm not sure if 1 is the main UI thread or not. In the extended MapActivity class I have, the onCreate method's Thread.currentThread().getId() returns 1 but I'm not sure if the MapActivity class is executed in the main ui thread? Here Romain Guy mentions that the onPostExecute method should have @Override but when I do that eclipse flags it as an error
"The method onPostExecute(Boolean...) of type TileCache.ImageLoadTask must override or implement a supertype method"
So I guess something is wrong there but the only fix eclipse offers is to remove the @Override
So I guess with out post all my source code, the question's I have are:
Is the MapActivity onCreate method called in the main ui thread?
What does the @Override error mean? or why does it show that error
Does anyone have an example of a custom tile overlay implementation with background image loading and tile caching?
Anyone know how to disable SMS threading on the Moment? I was able to do it via registry tom-foolery on my last phone (Palm Treo Pro), but I don't know where to start on this Android phone. I like having each SMS be its own little thing, not a string of SMS's.

When i hit home or whatever to get out of messaging, whenever i get another text, lets say its from another person. I can pull down my notification bar, click the new text, and it just opens up the text i was last in. I think its weird how it wont open the next text message, possibly because the app was running in the background the whole time?
View 3 Replies View RelatedSurprisingly, I don't seem to have issues with the OpenGL side of things (which is very unusual), but my problems stem from getting a clear idea for app architecture and a few other problems. Right now, most tutorials on the net just describe the render portion. I know that when I create a GLSurfaceView and hook a Renderer into it, it uses it's own thread for rendering.
I want to do logic operations and other gameplay stuff (like moving characters and whatnot) in it's own thread as well. Can anyone explain a good approach to this? I'm guessing the two threads will have to be synchronized (do logic, render, repeat), and limited based on time so that it performs smoothly across different devices.
I'm using an horizontal progress bar in my Android application, and I want to change its progress color (which is Yellow by default). How can I do it using code (not XML)?

View 1 Replies View RelatedI have a user complaining about a FC on my app and they were kind enough to post the stacktrace. It's a class that I cannot find anywhere and it sounds like it is related to multi-touch. I don't specifically call this class, MapView does so I don't have any control over it. It kind of looks like his Google API maps package is trying to use an unknown gesture library. Any ideas? I figure other devs using the MapView class might run into the same issue with their users. The user is using a Droid.

Android Developers Blog: Multitasking the Android Way
and it talks about how Android itself handles multitasking. The problem I'm running into is this: I stopped using Advanced Task Killer because people are saying that it's not healthy for your device, which makes sense to me as it seems like you're using CTRL ALT DELETE to close a program every time, and that just doesn't seem like a good idea.I understand that this isn't windows and it works completely different, but I still stopped using it because it seemed a bit harsh.After reading the above article I realize that this is how Android itself closes apps, by "brutally killing them" as the article says.If this is how Android itself closes apps when it needs more memory, why are task killers not a good idea?
If somebody could dumb it down for me so I can understand I'd appreciate it, as I'm a total Android n00b.

View 4 Replies View RelatedI understand that userland apps on android cannot set the system clock. Wanting to know more about how the security mechanism is set up for the system I did some digging around in the source code.
/dev/alarm is opened R/W to set the system clock using SystemClock.setCurrentTimeMillis.
How the permissions work to determine whether or not an application has permission to set the clock.
I assume it's just a user level permission, and the write bit for /dev/ alarm is only enabled for the "system user" and not the "userland user" applications run under.

View 4 Replies View RelatedMy app contains a page with a form, a long list of EditTexts.
If you're entering text and click the back button, the soft keyboard is hidden. However different android versions behave in different ways. My 2.2 device hides the keyboard, and that's it. My 1.5 device hides the keyboard, and the 'back' onKeyDown/Up event is still activated.
This is very tricky... for the 1.5 device I need to know if the keyboard is being displayed when the back button is pressed, so that I can capture the back event and stop it continuing (all I want is for the keyboard to hide). But I've search all over this forum and there doesn't appear to be a sure way of doing this.
