Hi,

I am not really sure if this is from my set up or something else. I tried to upgrade to scala 2.9.1 by using ant. When I run it, I get this error:

I am not sure if it is my setup because now I tried to generate your project jar file for 2.9.1 it gives me and error on sbt publish-local saying

target/src_managed/main/scala/org/positronicnet/libresources/TR.scala:3: object android is not a member of package
[error] import root.android.view.View

So it is a double whammy for me. Thank you for your help or suggestion.

The following code:

class MyActivity extends PositronicActivity with TypedActivity {
onCreate {
    findView(TR.button_id).onClick {}
  }
}

causes Eclipse to complain, since an android.widget.Button is returned by findView(), rather than a PositronicButton. Some implicit conversions would probably help, or I may be doing something wrong.

Thanks for a great project!

Hi,

I was not able to compile the sample as is with the project code. So I just moved the code into my project which has the setup. However, I get this weird and (I hope it is appropriate to say) hairy issue with byte code and delvik dec again.

I am not sure if there is any way to get around this? Thank you for your help.

Hi,

Thank you for putting the code out. I am trying out your lib by compiling it against 2.8.2. And this is the error I get.

[error] /Volumes/space/Projects/Java/positronic_net/src/main/scala/ui/ResourceId.scala:27: value reduce is not a member of Array[String]
[error] /Volumes/space/Projects/Java/positronic_net/src/main/scala/ui/ResourceId.scala:27: value reduce is not a member of Array[String]
[error] components.slice(0, numComponents).reduce(_ + "." + )
[error] components.slice(0, numComponents).reduce( + "." + _)

I looked at the source and tried to change that to map but still didn't get it to work. It is just one place that is failing. So I hope you would make the change to support the 2.8.2 code. Thanks for your help.

Hi, thanks for your work. I experimented with you code a while back and I quite like it. And it looks like the code has not been updated for a while. Would you plan to by any chance? Or if this is already abandoned. Thanks again for your help and work.

The current QueueRunnerThread implementation returns a handler to the future upon creation.

However, this handler is not being passed an instance of the HandlerThread's looper!
The looper is only available once HandlerThread.onLooperPrepared has been called.

class QueueRunnerThread
  extends HandlerThread( this.toString )
{
  override def onLooperPrepared() = {
    threadHandlerFut.succeed( new Handler(getLooper()) )
  }
}

Add a section to the README with a line I can copy and paste into my sbt project.scala, maybe just below the mention of the installation instructions link.
