问题 I've converted my Android app to a playbook bar; it works (with a lot of graphical bugs); however I'd like to know if it is possible to debug the software while it's running. Of course, I don't ask for the "luxury" of an adb equivalent, but at the very least, I'd like to get some printf. 回答1: You can use the standard Log.d("Tag", "Message text"); logging methods and watch the info in LogCat, as well as set a breakpoint and start debugging in Eclipse. I just verified it, the breakpoint was hit

问题 Is There any way by which we can have album art of any music file , i am able to extract file detail like album name , length , author , genre , track info. But i am intresred in to showing album art image. Please help 回答1: Apparently someone on this page managed to write some code to extract the image's data as a ByteArray, then finally load it through a Loader object. Here's the code they came up with: var binaryData:ByteArray; var file:URLLoader = new URLLoader(new URLRequest("test.mp3"));

问题 I don't even know how to explain this behavior but I'll try. I am loading images from an external url that requires basic auth so I am using URLLoader to load the image from a unique ID. The ID gets passed to the itemrenderer which then proceeds to load the image. But the images switch around on their own when I scroll. If I load more than 7 images or so it starts repeating images.... Youtube video of error: http://www.youtube.com/watch?v=ZYoqlS14gWQ Relevant code: <s:ItemRenderer name=

问题 I've got the NDK set up and managed to compile and run the hello native sdk project on my playbook. I downloaded the blackberry sdl port from github. However I've been unable to compile even a hello world project using it. Also it seems to be lacking a "lib" folder which I'm used to needing for the compiler settings. EDIT: I have managed to get the sdl to open in the native sdk, it seems the download was designed to act as a project template of sorts. At first the compiler complained that i

问题 I would like to know whether PhoneGap sdk supports Blackberry OS 10 build?

问题 I wanted to port my Android App to BB PB but then I noticed that none of my AdMob Ads where displaying. So I thought this might be because most of the AdMob Ads refere to Android Apps on the Playstore. Therefore these can't be displayed because the PB hasn't got a Play Store. My Question: How can I display Ads in my Android-PB App? Is there a solution for AdMob Ads or should I use an other service? 回答1: You can't display any Admob ads in Playbook currently, the current workaround I use it to

问题 I am working on a Flex TabbedViewNavigatorApplication with three tabs (ViewNavigator elements). I would like to switch from one ViewNavigator to another based upon a user action (via ActionScript code). I know that switching between Views uses pushView and popView , but I'm working with ViewNavigators, and my searching revealed nothing useful. I'm trying to switch from Tab2 to Tab1 when an event occurs. In this case, Tab2 contains a list, and when the user makes a selection, I want to jump
