区块链钱包-android篇

?首先根目录gradle中添加依赖：

? First, add dependency to the root directory & #xff1a;

?然后项目文件中添加plugin，添加依赖包：

? then add plugin， in the project document; add a dependency package & #xff1a;

?最后main下添加proto路径，添加proto文件；

? Last main add proto path & #xff0c; add proto file & #xff1b;

?

? ? ? ?关于tron的基础类，我整理了个lib，使用时直接导入lib即可。

♪ ♪ about the tron base class ♪ #xff0c; I sorted out a lib， directly import lib when used. ♪

? ? ? ?主要包括wallet钱包类，管理类等内容。

♪ ♪ Mainly includes the Wallet Wallet class ♪ #xff0c; management class. ♪

? ? ? ?

?这里我主要贴出wallet的代码

♪ Here I post the wallet code ♪

? ? ?

? ? ?其实就一步操作，就是根据私钥 创建wallet对象。

♪ It's actually a step-by-step operation ♪ ♪ xff0c; it's the creation of a walklet object based on a private key. ♪

? ? ? ?创建钱包需要两个参数，一个是钱包名称，一个是设置的密码，钱包名称还好，重要的是密码，因为转账，导出私钥助记词等信息时，都是需要密码验证的。

♪ ♪ ♪ The wallet needs two parameters to be created xff0c; one is the wallet name xff0c; one is the set password xff0c; the wallet name is still good xff0c; the important thing is the password xff0c; because the transfer xff0c; the export of private key helpwords and other information xff0c; all require password validation.

store方法是使用SharedPreferences存储当前钱包的信息，其中我们可以通过密码来获取wallet的eckey从而得到钱包的公钥和私钥。

The store method is to store the information on the current wallet using SharadPreferences & #xff0c; in this, we can access Wallet's eckey by password and get the public and private keys to the wallet.

? ? ? 这里主要用到项目中grpcClient类和walletmanager类。

♪ This is used mainly in the grpcClient and walletmanager categories of the project.

? ? ? 这个类主要封装了对应的网络请求以及钱包管理

♪ This class mainly covers the corresponding network requests and wallet management

? ? ? ?grpcClient类的initGrpc需要传入对应的fullnode和soliditynode，这个可以去下面的地址去选择，

♪ ♪ grpcClit type initGrpc needs to be passed on to the corresponding fullnode and soliditynode， this can go to the address below to select xff0c;

?查询账户需要用到账户的地址：

? search accounts need to use the account address xff1a;

? account可以查询balance和FrozenList；

? account can query balance and FrozenList；

accountNetMessage 可以查询账户的带宽信息。

AccountNetMessage can query the bandwidth information of the account.

具体代码如下：

The codes are as follows: xff1a;

?

? ? ?

根据上面的代码，获取到mTransactionUnsigned ，然后输入密码校验密码并获取到wallet的eckey。

Based on the code above & #xff0c; obtained from mTransactionUnsigned & #xff0c; then entered the password to verify the password and obtained the wallet eckey.

设置时间戳，交易签名。

Sets the time stamp xff0c; transaction signature.

最后一步是广播交易。

The last step is the broadcast trade.

具体的代码可查看git。

The specific code can be viewed as git.
