Cannot use .aidl file

[SamiunNafis]

Hi,

I'm trying to use an AIDL file in CodeAssist but I'm unable to import the package. The project is related to OpenVPN.

When I import the package it shows

Error
de.blinkt.openvpn.api.ExternalCertificateProvider
is not public in de.blinkt.openvpn.api; cannot be accessed from outside package [ExtAuthHelper.java: $line]

App version: 0.2.9-alpha Mobile phone: Micromax B5 Pro

Please let me know if you need any additional information or if there are any other solutions I can try.

Thank you for your help.
