try to invoke the help of Erel

 

[Erel]

Where is the link to the project?

 

[liulifeng77]

here is the demo.
I asked the abmaterial author,he said:You better ask this question in the B4A forum to the writer of WebViewExtras because this has nothing to do with ABMaterial. It just generates the B4A code.
so I ask for your help!
thanks!

Where is abmcontrollerb4a library?

 

[liulifeng77]

sorry,i forget it.now here it is.

 

[Erel]

I'm getting this error:
unsupported class file version 52.0
...while parsing com/ab/abmcontrollerb4a/ABMController.class

Seems like it was compiled with target level set to Java 8. It should be recompiled with the target set to Java 7.

thanks,Erel, but Alwaysbusy said, his running envirment is:
JDK: 1.8.0.60
Android API: 19.

 

[liulifeng77]

thanks you,Erel, it' solved. Alwaysbusy compiled a new library by jkd1.7.
