创建keystore文件

android studio 菜单 -> buid -> Generate Signed Apk 创建jks后缀的签名件 

然后在build.grade 中引用

android {
    signingConfigs {
        config01 {
            keyAlias 'MXXXXE'
            keyPassword 'XXXXX'
            storeFile file("E:/XXXXX/focusdict.jks")
            storePassword 'XXXXX'
        }
