I'm trying to do an insert to a DB as a result of a user clicking on a button. I want to do the actual insert in the background, so it seems I should use a Handler to do this. The SQLite insert method takes a Context parameter. My problem is how do I get a valid Context inside the Runnable that will do the insert?

I'm having hard times getting my GL thread (from GLSurfaceView) to trigger some code execution within the UI thread (from Activity). I tried it in every possible way (well not every, I missed at least the good one) none worked.
My idea was to get something called from the UI thread (to update some widgets) when the surface is effectively created. So I added to my onSurfaceCreated method the following call:
CODE:.............
This compiles, but when my GLSurfaceView sub-class is constructed a NoClassDefFound exception is thrown, telling me that the class com.my.package.MyGLSurfaceView$1 is not found.
Here's the log:
CODE:.............
The line 297 in MySurfaceView.java is:
private Runnable mUpdater = new Runable () { public void run () { [...] } };
I didn't found clear answer for why my code does not work. I assume it is because I am trying to update textview from runnable. Anybody know some workaround? Code isn't clean off course, I am happy to get that working so far as I am totally new in java.
CODE:...............................
I've been a couple of days trying to solve this thing but I can'f figure it out.The problem is, simple activity, with simple layout, ScrollView -> LinearLayout -> and a lot of buttons inside the layout (within the scroll content). Everything works just fine but one tricky thing. When I click a button let's say at the top of the scroll content and inmediatelly I scroll down to the bottom of the content and I click other button there, nothing happens until I click a second time and all come to normal again.This can be reproduced anytime and it's code independent (i've tried more than 20 scenarios). I've not much experience in android yet but looks like the scroll listener stops the onclick listener or something like that.
View 1 Replies View RelatedIn an existing Android project I've encountered the following piece of code (where I inserted the debugging litter) code...
with not a trace of the messages from the Runnable. So appearantly the Runnable doesn't run(), although img.post() returns true. Pulling the ImageView in onCreate() and declaring it final doesn't help.
I'm clueless. Simply setting the bitmap directly, while blocking the UI thread, does fix things, but I want to get things right. Does anybody understand what's going on here?

I developed one small application to display some text at defined intervals in the android emulator screen.I am using Handler class, small snippet from my code...
When i run this appication the text is displayed only one time.Please any one knows how to run a thread using Handler.
So I've been extremely frustrated by this for a long time now.I've posted before, but can't seem to find a good solution. My goal is to have something pretty much exactly like the installed application details page in the Android Market.I need a list of items displayed along with other content above the list, and would like the content above to scroll up along with the list (exactly like the application details does for the "My Review" and other descriptive info).Due to responses to my previous posts, I came to believe that it really wasn't possible to do this with a ListView.So rather than using a ListView, I refactored my code to use a simple LinearLayout and add individual View items to the list, thinking I could just set each View as clickable and add an OnClickListener to each View in the LinearLayout.That's not working at all though, and now I'm getting even more frustrated.If someone can help me get the OnClickListener working, then I think it'll work, but I do need a separator for the LinearLayout.How do I add a separator like the one used for ListView to my LinearLayout?

The documentation shows that you can directly link to your app on Android Market place. But every HTTP url I attempted, I am getting a page not found error. I am wondering if there is something wrong with the documentation or is there a rules change where we can directly link to apps we created. if that is the case, why is this documentation still exist pointing to incorrect information?

I am struggling to find a way to determine if a valid network is available to an app. specifically, if there's a problem making a network connection, i would like to be determine if it's on the client (app) side, or a problem with the remote server. i happen to be attempting a URL connection (using http client) and the wide and varied possible exceptions don't seem like a reliable method. for example, when the network is down on the phone, i received "unknown host exception", which doesn't really indicate the root cause ... it's possible to get that exception with a valid network connection also. at other times i get other exceptions, such as socket exception. is there a way to ask the phone if it's network ready? the other option i thought was to ping a known good server to see if it responds ... with an IP address. kind of a heavy weight option and not foolproof.

I switched to a Droid X yesterday (and am loving it) from the original Motorola Droid with QWERTY. My original Droid had the 2.2 Froyo update with the Flash 10.1 and I could watch all the movies on Iphonemovies.net on it. I got my Droid X and the Froyo update was available with the flash player which I installed but now when I go to Iphonemovies.net it is telling me "Sorry, this video is not valid for streaming to this device." Anyone else come across this? Is this a format thing that needs to be set/changed on the actual Droid X device or is it a problem on the website end where the Droid is so new it's not recognizing it. And yes, I have Flashplayer on it now.
View 4 Replies View RelatedI have an application that utilizes the phones DeviceID in various ways. I am now getting emails from users who have the HTC Droid Incredible phone that they are getting the error message I have added to the app that is showing the DeviceID being returned is not valid - which means it is either empty/null or the default ID used in the emulator. I require a valid DeviceID to use my app, and the permissions are all set fine in the XML. It works just fine on every other device, and now suddenly it seems to stop working on this phone. Anyone else having this issue? Anyone find out what is causing it? Does HTC now block this ID on this device?

I'm trying to upload an app to the market, but am getting the following error.
"The icon for your application is not valid. Please use a 48x48 PNG."
I checked my icon and its definately PNG and 48x48.
I've tried re-creating my eclipse project and workspace, tried using both GIMP and IrfanView to write out the PNG. None of this helped. I also tried using an icon from another app I wrote, and which had no problems being uploaded. Even this didn't work. I'm beginning to think its a bug in the market.

The whole process works fine, while the main activity is in the foreground. But, when I go to another activity (e.g. settings), the video recording works in the background only until max duration is reached. The file is saved, but a new sequence can not be started
because prepare() fails, apparently because setPreviewDisplay() doesn't like not having a proper surface to attach to.
