Original: Is there a way to kill a child activity of a TabActivity. I have a very simple tab setup. There are two tabs. One of the tabs contains a MapActivity. When I switch to the MapActivity the GPS turns on. When I press back, the TabActivity exits, but the GPS is still on. The gps doesn’t turn off until I explicitly kill the app. Is there a way to kill the MapActivity from the TabActivity? I would like to kill it when TabActivity exits/onBackPressed.Edit: I do attempt to stop location reques

android memory-management linux-kernel arm page-fault
I am trying to debug a problem in which an application is triggering continuous data aborts due to invalid memory access.I have following queries.In general when an application in Android(CPU ARM) is accessing an invalid memory access, what happens?I guess a page fault would occur and then a data abort would be triggered. Is it so? Could someone briefly explain how does Android handle invalid memory access? What happens to the process which makes illegal memory access? Is it restarted again and

I’ve been playing around with both dungeons sample in app billing code with google and blundell’s tutorial in app billing code. Both of these projects are basically out of the box besides changing the public key, renaming the application, and uploading it to google which I have already done. The two apps were working fine just recently (around 3 days ago). Now i’m getting this error both in the LogCat and the Device.Device:Error retrieving information from server.

javascript regex eclipse escaping
I have a regular expression testing for numbers(0-9) and/or forwardslashes (/). It looks like this:/^[0-9/]+$/i.test(value)Now I believe this to be correct, but the eclipse javascript validator disagrees:Syntax error on token “]”, delete this tokenI suppose this is because the separator/delimiter is / and eclipse ‘thinks’ the regex is finished (and therefore a ] would be unexpected). We can satisfy eclipse by escaping the / like so:/^[0-9\/]+$/i.test(value)Note that both versions work for me.My

java eclipse noclassdeffounderror dropbox
I use Eclipse to write Java code and use DropBox to sync my code with others’ across our multiple computers. Most of the time, everything works as expected: if anyone makes a change on either end, the change is saved and when the other person refreshes the Eclipse workspace, the changes come through and can be viewed and run successfully.Sometimes, one of several errors arises. Sometimes Eclipse says it cannot find a main class and sometimes it says it could not find the class itself. Sometimes

I am working on a solution that aims at solving problems that newbie programmers experience when they are “modifying code” while bug fixing / doing change requests, on code in production. Eclipse, as we all know is a great IDE. Features such as Code Completion, Open Declaration, Type Hierarchy, Package Explorer, Navigator, Finding References etc aids people in fixing things quicker compared to say using something like Textpad.If you are a newbie java programmer and you are using Eclipse IDE, wha

We are writing a Web-based events calendar with thousands of theatre shows, festivals, and concerts in a SQL database.The user goes to the Website, performs a search, the SQL server returns JSON, and jQuery code on the client side displays the 200+ events.Our problem is that each event has an image. If I return URLs, the browser has to make 200+ HTTP GET requests for these tiny (2-4Kb) images.It is tempting to pack all the images into one CSS sprite, but since the user searches can return any co

java base64 apache-commons codec
How can I install the commons codec? I’ve downloaded but I’ve searched online and couldn’t find an answer to this. I want to use the Base64 encoder and decoder. Also 1 more question, if my code uses this codec, will other users that try to use my program require it too? or is it just compiling?Thanks

java scala base64 apache-commons
I’m using the Base64 encoder from the Apache Commons library. Now either something funny is going on with my runtime/IDE, or their implementation of Base64 encoding (or Base64 as a specification) is non-deterministic:val test = Base64.encodeBase64(“hello”.getBytes).toString val test2 = Base64.encodeBase64(“hello”.getBytes).toString val test3 = Base64.encodeBase64(“hello”.getBytes).toStringEach of the above produce different results. Is this expected? I’m writing this in Scala…
