How can I sign message

[s2g090123]

I can connect to metamask, and get the wallet address.
Now, I want to sign message by the address.

I use

Session.preformMethodCall(
     Session.MethodCall.SignMessage(
          System.currentTimeMillis(),
          address,
          message
     ),
     callback
)

But the callback didn't be invoked.

I paste my log below here:

I am having the same issue, Did you find any workaround for this.

SignMessage is eth_sign ，if you want sign "ethsignTypedData"

session.performMethodCall(Session.MethodCall.Custom(System.currentTimeMillis(),"eth_signTypedData",parmList),::handleResponse)

SignMessage 是 eth_sign ，如果要签名 "ethsignTypedData"

session.performMethodCall(Session.MethodCall.Custom(System.currentTimeMillis(),"eth_signTypedData",parmList),::handleResponse)

I want to know where is this method called parmList and what are the parameters
