Erel B4X founder Staff member Licensed User Longtime User Jun 19, 2012 #1 Basic4android v2.00 is now available. This upgrade is probably the most significant upgrade since v1.00. The major new feature is support for class modules. With support for classes Basic4android now allows you to write both procedural code and object oriented code. Object oriented code makes it easier to write and maintain large projects. Basic4android v2.00 improvements: - Classes - Public and Private access modifiers - Built-in documentation - Better handling of tasks in the internal thread pool - CallSubDelayed keywords - These keywords significantly simplify the interaction between services and activities. - Building process improved and it now supports libraries with embedded resources (such as PayPal, Zooz, Samsung Pen and others). - Bug fixes and other minor improvements. Note that B4A.xml was modified in this version. The highlighting styles section was not modified. The Reflection library was updated to support the new version internal changes. V2.02 is now available. You should use the same link as the link to v2.00. This version fixes several issues related to CallSub and CallSubDelayed keywords.

rayzrocket Member Licensed User Longtime User Jun 26, 2012 #62 Ver1.70 is very code fault tolerant than Ver2.00 B4A Ver2.00, Bravo Erel! This may help some of those struggling with debugging code after Ver2.00 update. Ver1.7 sometimes(everytime in my cases) allows "CallSub" into paused activities. 2.0 will not tolerate this!, the app will run, but consistently break down, stop functioning, error, or crash the phone whenever a "CallSub" is made into a paused activity (this goes for both activities and service modules). It is very hard to debug via app runtime. Upvote 0

I can't wait to try this tonight! can't believe I missed the original email and didn't see it till today Writing stuff without classes felt like I was a pirate with a wooden leg and a missing eye lol It's not that you can't win a fight, but... it's just easier if you're a ninja with all your limbs and 2 swords Upvote 0

Erel B4X founder Staff member Licensed User Longtime User Jun 27, 2012 #65 About the CallSub issue. There is a bug in v2.00 where CallSub fails instead of doing nothing when the activity is paused. Previously it just did nothing. This is fixed in the next update which will soon be available. Note that it is much better to use CallSubDelayed when interacting with other modules. @PeakW, you should download the latest Reflection library. It fixes this issue (see the first post here).

T trisium Member Licensed User Longtime User Jun 27, 2012 #67 problems with existing projects after installing v2.00 After installing version 2.0 (updating version 1.9) I get problems with my existing projects (working fine on version 1.9). Opening an project produces this message: "An error occured. Der Verzeichnisname ist ungültig." I think this happens in the context with Java??? Compiling the project results in this message: "Compiling code. 0.77 Compiling layouts code. 0.06 Generating R file. 0.02 Compiling generated Java code. Error Der Verzeichnisname ist ungültig" I use no additional libraries and I have no idea, which folder name is meant... Reinstalling 1.9 solves the problems... What could be the solution? :sign0085: Thanks! Upvote 0

Thanks a lot Klaus, but I see no problems at this place - the paths are: D:\Java\jdk1.7.0\bin\javac.exe D:\Android\android-sdk\platforms\android-14\android.jar Both paths/files exist - and work fine with version 1.9. I would be happy about other hints!!! Upvote 0

kanaida Active Member Licensed User Longtime User Jun 27, 2012 #75 Timers in classes Hey Erel, just tried creating a simple project. It's mostly just one class 'Car'. It's got a timer inside, when the Car.StartEngine() is run, it changes the color of it's internal view every second. (it's just a box right now lol) I put the timer in there just to see if it could animate independently of what my activity was doing, so by changing an interval or variable like speed, the wheels would animate faster or slower. I got a nasty log message after the first tick though...
