第一、Android端打包

簽名步驟：

1.首先找到Studio =====> Build ====>Generate Signed Bundle / APK

2.輸入key Store 存放地址，設(shè)置密碼，建議存放在項(xiàng)目，

3.如圖所示：

標(biāo)注1：是存放在項(xiàng)目app下面的密鑰

標(biāo)注2：新建file文件key.properties 存放的是密碼，密鑰，別名

storePassword=111111

keyPassword=111111

keyAlias=flutter

storeFile=../flutter_key_store

標(biāo)注3：新建proguard-rules.pro存放的是 代碼混淆的配置

注意：這個(gè)配置要放在/android/app/proguard-rules.pro

-keep class io.flutter.app.** { *; }

-keep class io.flutter.plugin.** { *; }

-keep class io.flutter.util.** { *; }

-keep class io.flutter.view.** { *; }

-keep class io.flutter.** { *; }

-keep class io.flutter.plugins.** { *; }

在 build.gradle 中進(jìn)行配置密鑰和代碼混淆

在build.gradle android 上面進(jìn)行配置

def keystoreProperties =new Properties()

def keystorePropertiesFile =rootProject.file('key.properties')

if (keystorePropertiesFile.exists()) {

keystoreProperties.load(new FileInputStream(keystorePropertiesFile))

}

在build.gradle android 里面進(jìn)行配置

signingConfigs{

release{

    //設(shè)置密鑰配置

    keyAlias keystoreProperties['keyAlias']

    keyPassword keystoreProperties['keyPassword']

    storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) :null

    storePassword keystoreProperties['storePassword']

}

}

buildTypes{

release{

    signingConfig signingConfigs.release

   //代碼混淆需要添加的

    minifyEnabledtrue  //資源壓縮設(shè)置

    useProguardtrue    //代碼壓縮設(shè)置

   //讀取代碼壓縮配置文件

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

}

}

4.直接打包APK
