Hi haXe list, I need to implement a kind of http streaming on my haxe project.
It is something where the browser is always keeping a connection open to the server, so the server can push data to the client. Is there anybody here than have any experiences or advices on how to implement that ? thanks Nico Le 4 févr. 2010, 6:53 PM, <[email protected]<android-developers%[email protected]>> a écrit : Today's Topic Summary Group: http://groups.google.com/group/android-developers/topics - How to use a Live Wallpaper in an Activity?<#1269a1de8b07b324_group_thread_0>[2 Updates] - How to show a message during incoming call?<#1269a1de8b07b324_group_thread_1>[1 Update] - Textview with graphic (dynamically changing) inside.<#1269a1de8b07b324_group_thread_2>[1 Update] - Preventing WakeLock Under-Locked exception<#1269a1de8b07b324_group_thread_3>[2 Updates] - Add languages to arm-eabi-gcc <#1269a1de8b07b324_group_thread_4> [1 Update] - drawing word-wrapped text at arbitrary position on a canvas<#1269a1de8b07b324_group_thread_5>[1 Update] - how to stop accelerometer sensor running in background?<#1269a1de8b07b324_group_thread_6>[4 Updates] - How to show a loading image or an animation?<#1269a1de8b07b324_group_thread_7>[1 Update] - Bug report for 2.0.1.

JP <[email protected]> Feb 04 07:12AM -0800 ^<#1269a1de8b07b324_digest_top> There's more to it than onStop(). Check out onPause(), or better yet, revisit the documentation on the Activity model. So you get sense of the dynamic, override all activity methods, place logs in them and play around so you get a feel which method gets called when. JFrog <[email protected]> Feb 04 09:28AM -0800 ^<#1269a1de8b07b324_digest_top> I believe when I had been running across handling sensor inputs there was always the finish( ) functionality included in my onStop( ) in order to finalize the end of the Activity. Of course there will always be a provider for the Android sensors out there that the system is supplying.

When I'm scrolling the list the scroll works pretty smooth however when/if I'm trying to continue the scroll in the middle of the last scrolling the scroll just stops and sometimes the item I clicked on is selected (I have registered an OnClickListener to the item view). I would like to get smooth scrolling just as in the device native contact list. My implementation builds each contact a view containing: 1. Big picture for the contact image. 2. Small picture for the type of the contact. 3. TextView with the Contact name 4. TextView with some extra text about that contact. My current layout for every item looks like: <LinearLayout > <ImageView /> <LinearLayout/> <LinearLayout/> <ImageView /> <TextView/> </LinearLayout> <TextView/> </LinearLayout> </LinearLayout> I've tried changing the LinearLayouts to relative ones but saw no improvement in performance. I've created my own "Selector" in code (to eliminate the time it takes to load the resource) so that odd rows will have different background color. The code looks like: StateListDrawable draw = new StateListDrawable(); draw.addState(new int[] {android.R.attr.state_selected}, mSelectedRowDrawable); draw.addState(new int[] {-99},mOddRowBG); draw.addState(new int[] {},mRowBG); view.setBackgroundDrawable(draw); I'll be glad to give more details if needed. Thanks for the help. Topic: Draw clock like minute hand<http://groups.google.com/group/android-developers/t/7d767372f9f340a4> Sonic <[email protected]> Feb 04 07:37AM -0800 ^<#1269a1de8b07b324_digest_top> Hi all. Just a quick question, how would i go about implementing a clock like hand that rotates around a centre point to different positions depending on a value. e.g. I send it a value of 3, and it points to the 3'o'clock position of a circle. protected void onDraw(Canvas canvas) { Paint line = new Paint(); line.setStrokeWidth(3); line.setColor(Color.BLUE); line.setStyle(Paint.Style.STROKE); canvas.drawLine(55, 155, 125, 15, line); } I have the following fully working so it draws the line, but i dont understand how i could get one end of the line to always rotate around the centre fixed position. Do you have any ideas? Thanks.

The default built.xml can be copied to the tests folder and change the name of the project in build.xml to your test project's name. 2. You also need the build.properties application.package=your_test_package_name ( This has to be different than your tested project for obvious reasons) tested.project.dir=.. tested.project.absolute.dir=.. The remaining two properties are the location of your actual project you are testing All this is evident if you read the build.xml file and the template rules. (and I stand corrected on my previous post, the documentation is in the build.xml file and not in the template files ).

MrChaz already pointed you to the class and function you need to use. Reading the documentation on the function and playing with it for about 5 minutes should be all you need to get going. ------------------------------------------------------------------------------------------------- TreKing - Chicago transit tracking app for Android-powered devices http://sites.google.com/site/rezmobileapps/treking Topic: Basic Emma code coverage tutorial needed<http://groups.google.com/group/android-developers/t/3243be1537f0417e> Chander Pechetty <[email protected]> Feb 04 07:07AM -0800 ^<#1269a1de8b07b324_digest_top> I just replied a gentleman on this forum at http://bit.ly/cikIiz.

But... since the multiple ContentProvider instances are running in different process space, how do they access the DB file that was created in different process space or user ID?
