我試圖通過使用go-ethereum庫的移動(android)與智能合約進行交互。Go-Ethereum:Android智能合約交互問題

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; 
    } 
} 

預期的行爲

與上Rinkeby blockchain部署智能合同成功的互動。

實際行爲

對於設定部(合同): 'ABI:不能使用切片類型字符串作爲參數'

對於吸氣劑(合同): 「ABI:不能解組串在爲[]接口{}」

步驟來重現行爲

1通過移動

2)連接到Rinkeby Testnet)創建通過移動

3.帳戶)通過部署桌面智能合同

4)儘量W /通過移動智能交互合同

底線

如果有人已經能夠通過中間人復仇的Android智能合同進行互動, 我希望得到一些assistanc即
