1 app项目中保存签名信息

 signingConfigs {
        releaseConfig {
            storeFile file("aa.key")
            storePassword "pwd"
            keyAlias "alias"
            keyPassword "pwd"
        }
    }

将aa.key签名文件复制到app module目录下

2 加快DEX文件的生成速度

 dexOptions {
    maxProcessCount 8
    javaMaxHeapSize "4g"
  }

3 混淆 压缩

release {
    shrinkResources true
    minifyEnabled true
    proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
