使用codenameone蓝牙支持时出错

Question

I am building an app that uses bluetooth support. After adding the libs and refreshing as directed here https://github.com/chen-fishbein/bluetoothle-codenameone , Below is the error log

Compile is forcing compliance to the supported API's/features for maximum device compatibility. This allows smaller code size and wider device support

Any help and reason as to why it happened would be much appreciated. Thanks

cn1lib's are just zip files so make sure you downloaded the right file by verifying that it's a valid zip file.

You can use the new extension install tool to install the library more easily.
