我试图通过使用go-ethereum库的移动(android)与智能合约进行交互。Go-Ethereum:Android智能合约交互问题

的Android

final String address_string = "0x8607e627604495ae9812c22bb1c98bdcba581978"; 
String abi = "[{\"constant\":false,\"inputs\":[],\"name\":\"get_s\",\"outputs\":[{\"name\":\"\",\"type\":\"string\"}],\"payable\":false,\"type\":\"function\"},{\"constant\":false,\"inputs\":[{\"name\":\"new_s\",\"type\":\"string\"}],\"name\":\"set_s\",\"outputs\":[],\"payable\":false,\"type\":\"function\"},{\"inputs\":[{\"name\":\"d_s\",\"type\":\"string\"}],\"payable\":false,\"type\":\"constructor\"}]"; 
Address address = Geth.newAddressFromHex(address_string); 
BoundContract contract = Geth.bindContract(address, abi, ec); 
CallOpts callOpts = Geth.newCallOpts(); 
callOpts.setContext(ctx); 
callOpts.setGasLimit(31500); 
System.out.println("OUTPUT: " + getString(contract, callOpts)); 

//Setter String to Test Contract 
Interfaces params = Geth.newInterfaces(1); 
Interface anInterface = Geth.newInterface(); 
anInterface.setString(teststring); 
params.set(0,anInterface); 
return contract.transact(opts, "set_s", params); 

//Getter String from Test Contract 
Interfaces args = Geth.newInterfaces(0); 
Interfaces results = Geth.newInterfaces(1); 
Interface result = Geth.newInterface(); 
result.setDefaultString(); 
results.set(0, result); 
contract.call(opts, results, "get_s", args); 
String string = results.get(0).getString(); 
return string; 

合同

pragma solidity ^0.4.9; 

contract echo { 
    string s; 

    function echo(string d_s) { 
      s = d_s; 
    } 

    function set_s(string new_s) { 
      s = new_s; 
    } 

    function get_s() returns (string) { 
      return s; 
    } 
} 

预期的行为

与上Rinkeby blockchain部署智能合同成功的互动。

实际行为

对于设定部(合同): 'ABI:不能使用切片类型字符串作为参数'

对于吸气剂(合同): “ABI:不能解组串在为[]接口{}”

步骤来重现行为

1通过移动

2)连接到Rinkeby Testnet)创建通过移动

3.帐户)通过部署桌面智能合同

4)尽量W /通过移动智能交互合同

底线

如果有人已经能够通过中间人复仇的Android智能合同进行互动, 我希望得到一些assistanc即
