问题描述

基于此

Based On this thread I want to pass array of strings as argument lik this :

...
);

但显示错误:

不受支持的值:[Ljava.lang.String.

Unsupported value: [Ljava.lang.String .

我该怎么办?

推荐答案

StandardMessageCodec不支持数组(int和byte除外).对于对象，它支持Java集合，例如List和Map.将您的String数组更改为List<String>.

The StandardMessageCodec doesn't support arrays (except of int and byte). For objects, it supports Java collections, like List and Map. Change your array of String to a List<String>.

ArrayList<String> args = new ArrayList<>();
args.add("Hello");
args.add("Bye");
channel.invokeMethod("foo", args, new MethodChannel.Result(){
