Android build.gradle版本名打包配置的方法

1、生成密钥文件到app工程目录下

2、在gradle.properties文件下配置密钥文件信息

# project-wide gradle settings.
# ide (e.g. android studio) users:
# gradle settings configured through the ide *will override*
# any settings specified in this file.
# for more details on how to configure your build environment visit
# http://www.gradle.org/docs/current/userguide/build_environment.html
# specifies the jvm arguments used for the daemon process.
# the setting is particularly useful for tweaking memory settings.
org.gradle.jvmargs=-xmx1536m
# when configured, gradle will run in incubating parallel mode.
# this option should only be used with decoupled projects. more details, visit
# http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:decoupled_projects
# org.gradle.parallel=true
release_key_password=key-password
release_key_alias=key-alias
release_store_password=store-password
#jks文件名
release_store_file=sugr-ivy.jks

3、build.gradle文件下配置

apply plugin: 'com.android.application'

android {

  compilesdkversion 26
  project.archivesbasename = "appname"
  defaultconfig {
    applicationid "com.example.app"
    minsdkversion 23
    targetsdkversion 26
    versioncode 1
    versionname "1.4.0"
    testinstrumentationrunner "android.support.test.runner.androidjunitrunner"
  }

  signingconfigs {
    release {
      keyalias release_key_alias
      keypassword release_key_password
      storefile file(release_store_file)
      storepassword release_store_password
    }
    debug {
      keyalias release_key_alias
      keypassword release_key_password
      storefile file(release_store_file)
      storepassword release_store_password
    }
  }

  buildtypes {
    release {
      buildconfigfield "boolean", "log_debug", "false" // 不显示log
      minifyenabled false           //混淆
      proguardfiles getdefaultproguardfile('proguard-android.txt'), 'proguard-rules.pro'
      signingconfig signingconfigs.release  //签名
    }
    debug {
      signingconfig signingconfigs.debug  //签名
    }
  }

  applicationvariants.all {
    variant ->
      variant.outputs.all {
        calendar calendar = calendar.getinstance(locale.china);
        def builddate = string.format(locale.china, "%04d%02d%02d", calendar.get(calendar.year), calendar.get(calendar.month) + 1, calendar.get(calendar.day_of_month))
        def versionname = defaultconfig.versionname
        def versioncode = defaultconfig.versioncode
        //android studio3.0之前的写法
        //  output->output.outputfile=new file(output.outputfile.parent,output.outputfile.name.replace(".apk","-"+defaultconfig.versionname+".apk"))
        //android studio3.0的写法
        //项目名-版本名-版本号-release/debug.apk
        if (variant.buildtype.name.equals('release')) {
          outputfilename = "${project.archivesbasename}-v${versionname}-c${versioncode}-${builddate}-release.apk"
        } else {
          outputfilename = "${project.archivesbasename}-v${versionname}-c${versioncode}-${builddate}-debug.apk"
        }
      }
  }

}

dependencies {
  implementation filetree(dir: 'libs', include: ['*.jar'])
  testimplementation 'junit:junit:4.12'
  androidtestimplementation 'com.android.support.test:runner:1.0.2'
  androidtestimplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

  implementation 'com.android.support:appcompat-v7:26.1.0'
  implementation 'com.android.support.constraint:constraint-layout:1.1.3'
  implementation 'com.android.support:multidex:1.0.3'
  implementation 'com.android.support:recyclerview-v7:26.1.0'

}
