Android Studio编译release版本

1.在android studio界面的最左下脚，有两个icon：“Build Variants" 和”Favorities“，点击”Build Variants“，出现了 module，Variants对应界面。在要编译的module的右边，选择”release“。

->

2.参照Android Studio中创建keystore生成指定的证书文件。

3.app/build.gradle文件中增加 signingConfigs字段：如下所示：

android {

      defaultConfig {

           }

     signingConfigs {

         debug {

             File strFile = new File ( "../../Keystore/Debug/debug.jks" )

             storeFile file ( strFile )

             storePassword "storeDebug1234567890"

             keyAlias "debugkey"

             keyPassword "aliasDebug1234567890"

         

         }

         release {

             File strFile = new File ( "../../Keystore/Release/release.jks" )

             storeFile file ( strFile )

             storePassword "storeRelease1234567890"

             keyPassword "keyRelease1234567890"

             keyAlias "releasekey"

         

         }

     }

    

     buildTypes {

         release {

             signingConfig   signingConfigs . release

             runProguard false

             proguardFiles getDefaultProguardFile ( 'proguard-android.txt' ) , 'proguard-rules.pro'

         }

     }

}

4.然后，重新编译项目，编译出来的是release版本。
