ittleProxy-mitm on android.

[Anatame]

I'm trying to run LittleProxy-mitm on android with the code:

 val server = DefaultHttpProxyServer.bootstrap()
            .withAddress(InetSocketAddress("127.0.0.1",  8100))
            .withManInTheMiddle(CertificateSniffingMitmManager())
            .start() but the app crashes with this error.

java.lang.NoClassDefFoundError: Failed resolution of: Lorg/apache/commons/io/IOUtils;

Full error:

You have to import commons.io

implementation("commons-io:commons-io:2.4")
