ethwallet's Issues

借鉴你的UI，我做了一个功能完善的钱包

非常感谢你的开源的钱包UI ，我在钱包中加入了更丰富的功能， 可参考：https://github.com/xilibi2003/Upchain-wallet

卧槽 web3你用java写？

转账的bean还没有吗?

ModifyPassword

private boolean verifyPassword(String oldPwd, String newPwd, String newPwdAgain) { if (!TextUtils.equals(Md5Utils.md5(oldPwd), walletPwd)) { ToastUtils.showToast(R.string.modify_password_alert4); return false; } else if (TextUtils.equals(newPwd, newPwdAgain)) { // 判断有误 ToastUtils.showToast(R.string.modify_password_alert5); return false; } return true; }

// 内存溢出crash
WalletUtils.generateWalletFile(newPassword, keypair, destinationDirectory, true);

怎么将私钥转换为助记词

请教一下怎么将私钥转换为助记词，有没有简洁的方法，比如传入一个私钥，返回助记词
现在代码不完善，有问题：以私钥方式导入的钱包，导出助记词时为空。

大神什么时候再次更新...............

请教一下如何获取首页已选中的那个钱包的信息呢？

受用 谢谢

INSTALL_FAILED_NO_MATCHING_ABIS

android8.0以上 bitcoinj依赖库 提示INSTALL_FAILED_NO_MATCHING_ABIS，8.0以下运行正常

希望能加入转账功能

我想根据你这个钱包实现一个转账功能的钱包，目前不知道该如何着手，你会在后续加入吗。

受用

很好的作品

在研究以太坊、比特币、eos 方便加个好友么？qq：1840658279

如题，谢谢！

bitcoinj在有的手机上无法使用，一直installing

有什么解决方法?

请问首页资产怎么弄呀?

这个总资产跟余额怎么查询呢?

Failure [INSTALL_FAILED_NO_MATCHING_ABIS: Failed to extract native libraries, res=-113]

试过了下面两种方法都不能安装：
1.File ---> Settings ---> Build,Execution,Deployment ---> Instant Run
把Enable Instant Run to选项去掉
2.splits {
abi {
enable true
reset()
include 'x86', 'armeabi-v7a','x86_64'
universalApk true
}
}

修改密码的utils好像不对
