Event filter of a contract doesn't filter light client

Question

hello i use the env is android go ethereum light client not web3j not web3j i init geth code

        FilterQuery selfFQ = Geth.newFilterQuery();
        selfFQ.setTopics(Geth.newTopicsEmpty());
        selfFQ.setAddresses(Geth.newAddressesEmpty());
        Topics tps = selfFQ.getTopics();
        String strFunction = "ReturnValue(address,int256)";
        String HashStr = Sha3.hash(strFunction);
        List<String> topics = new ArrayList<>();
        topics.add("0x" + HashStr);
        tps.append(fromListToHashes(topics));
        selfFQ.setTopics(tps);
        node.getEthereumClient().subscribeFilterLogs(Geth.newContext(),selfFQ,new MyFilterLogsHandler(),16L);

then i receiver the log in bellow

    public void  onFilterLogs(org.ethereum.geth.Log var1){
    try{
        byte[] topics = var1.getTopics().get(0).getBytes();
        byte[] args = var1.getTopics().get(1).getBytes();
    }catch (Exception e){
        Log.d("111","onFilterLogs getTopics " + var1.toString());
    }
}

then i don't know how to parse the event and param ...... anybody can told me thanks

Answer 1

you will need abi to parse the event and inputs. I did the parsing in golang like this, abiParsed, err = abi.JSON(strings.NewReader(YourContract_ABI)) abiParsed.Events[eventName].Inputs.Unpack(v, rawLog.Data)
