io.eblock.eos4j.api.exception.ApiException: Internal Service Error
这个一般是什么导致的？我的nodeos是使用官网推荐的方式启动，RPC通讯是没有问题的：
$ curl http://localhost:8888/v1/chain/get_info

transfer时memo超过94个字符导致签名失败

94字符以下可正常transfer

对非转账交易进行签名 签名失败

一直提示 Provided keys, permissions, and delays do not satisfy declared authorizations

有发币的功能吗？

有线上RPC发币的功能吗？

转账精度问题

转账方法的 asset 序列化时，把 amount 处理成整数时，没有考虑小数点后位数超过 4 的情况，导致如果传的金额是 '100.12345 EOS' 时，转成的整数变成 '10012345', 而不是 '1001234'。
问题代码在这里

该库已经不再维护了，大家可以使用eos官方的库。

io.eblock.eos4j.api.utils.Generator类的createService调用多次会出现内存溢出

public class Generator {

private static OkHttpClient.Builder httpClient = new OkHttpClient.Builder();

private static Retrofit.Builder builder = new Retrofit.Builder()
		.addConverterFactory(JacksonConverterFactory.create());

private static Retrofit retrofit;

public static <S> S createService(Class<S> serviceClass, String baseUrl) {
	return createService(serviceClass, baseUrl, false);
}

public static <S> S createService(Class<S> serviceClass, String baseUrl, boolean debug) {
	if (debug) {
		HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
	    logging.setLevel(Level.BODY);
	    httpClient.addInterceptor(logging);
	}
	builder.baseUrl(baseUrl);
	OkHttpClient okHttpClient = httpClient.build();
	builder.client(okHttpClient);
	builder.addConverterFactory(JacksonConverterFactory.create()); //该行代码会造成内存溢出
	retrofit = builder.build();
	return retrofit.create(serviceClass);
}

public static <T> T executeSync(Call<T> call) throws Exception {
	Response<T> response = call.execute();
	if (response.isSuccessful()) {
		return response.body();
	} else {
		try {
			ApiError apiError = getApiError(response);
			throw new ApiException(apiError);
		} catch (ApiException e1) {
			throw e1;
		} catch (Exception e) {
			e.printStackTrace();
			ApiError apiError = new ApiError();
			io.eblock.eos4j.api.exception.Error error = new io.eblock.eos4j.api.exception.Error();
			error.setWhat("unknow exception");
			apiError.setError(error);
			throw new ApiException(apiError);
		}
	}
}

private static ApiError getApiError(Response<?> response) throws IOException, ApiException {
	return (ApiError) retrofit.responseBodyConverter(ApiError.class, new Annotation[0]).convert(response.errorBody());
}

}
builder是一个static变量，每次调用createService方法的时候调用builder.addConverterFactory(JacksonConverterFactory.create())，该行代码会往builder对象的converterFactories（ArrayList）变量插入一个JacksonConverterFactory.create()对象，如果调用次数过多，就会出现内存溢出；其实，在该类初始化的时候已经执行了
private static Retrofit.Builder builder = new Retrofit.Builder()
.addConverterFactory(JacksonConverterFactory.create());
，后面的createService方法就没必要再调用builder.addConverterFactory(JacksonConverterFactory.create());了

how to get data from table of contract

close 方法

https://github.com/EOSIO/eosio.contracts/blob/master/eosio.token/include/eosio.token/eosio.token.hpp#L36

没有实现这个方法。希望实现。

something about buy ram with eos

Map<String, Object> dataMap = new LinkedHashMap<>();
dataMap.put("payer", "testaccount1");
dataMap.put("receiver", "testaccount1");
dataMap.put("quant", new DataParam("2.0000 EOS", DataType.asset, Action.transfer).getValue());
TxAction action = new TxAction("testaccount1", “eosio”, "buyram", dataMap);
.....
// sgin
String sign = Ecc.signTransaction(pk, new TxSign(info.getChainId(), tx));//I am sure the pk is the privakey //of testaccount1,and just need the auth of active

I want to call this system method to buy ram with eos ,Will report such a mistake:
but does not have signatures for it under a provided delay of 0 ms, provided permissions []
I do not know why .

if use the method of buyrambytes and input right params can run success.

maven

没法用maven导入吗

  无法用gradle安装

Project gradle

allprojects {
    repositories {
        google()
        mavenCentral()
        jcenter()
        maven {
            url "https://jitpack.io"
        }
    }
}

app gradle

    implementation 'com.github.espritblock:eos4j:master-SNAPSHOT'

 错误信息：

Failed to resolve: com.github.espritblock:eos4j:master-SNAPSHOT

使用手机进行pushTransaction出现 unsatisfied_authorization 3090003 错误

同样的代码,在pc使用java直接进行转账是成功的,但是放在手机上跑就失败了

楼主，可以弄一个给a账号抵押cpu的方法吗？

就比如我自己想主账号想给小号抵押cpu，不想租，，还有就是赎回cpu的方法

可以用这个库来调用智能合约吗？

我在eos上用acchello发布了一个名为hello智能合约，有个函数hi(string account_name)，怎么用这个sdk去调用hi函数呢？

这个库有问题啊，会导致转账金额增加

详见https://www.bishijie.com/shendu_3507
