On Android 4.4 the library does not work, it crashes with the following trace error:

openbeans may be a replacement

talios commented 8 years ago

Just noticed this ticket - sorry I should have noticed sooner. Whats openbeans? The current develop branch is now all JDK8 based, so any change will need to be a backport/support branch.

I'll think about a cleanish way to try extract the use of getBeanInfo, or at least catch that exception and use normal reflection.

sebastianmacarescu commented 8 years ago

You can find more details about it here: https://github.com/melix/openbeans. It's a ported version of java.beans. I think you could catch that exception, as you specified, and use plain java reflection. Please let me know as the app I'm creating is unusable in android 4. Thanks

@sebastianmacarescu are you able to build that feature branch and give the resulting lib a bash in your project? Basically I just ripped out the introspector/property descriptor and went with basic reflection ( and added a missing test covering it ).

talios commented 8 years ago

Just released 4.0.5 which doesn't use introspector, openbeans is unfortunately available in central to use otherwise I would have pulled it in ( altho it also pulls in A LOT of code ).
