打包發布部分

S1.使用默認方式打包簽名APK

AndroidStudio選擇Build => Generate Signed APK

總體步驟流程如下：

詳細操作步驟：

S2. 多渠道打包APK

屬性配置

productFlavors

    productFlavors {

        aVer {

            resValue("string","strKey","myKey")

            applicationId "com.simple.pkg.debug"

        }

        bVer {

            applicationId "com.simple.pkg.beta"

        }

        cVer {

            applicationId "com.simple.pkg.res"

        }

    }

signingConfigs

    signingConfigs {

        release {

            storeFile file('E:/XXX/app.jks') // 簽名證書文件

            storePassword 'you password' // 證書密碼

            keyAlias 'test'

            keyPassword 'you password '

        }

    }

buildTypes

    buildTypes {

        mbeta {

            signingConfig android.signingConfigs.release

            minifyEnabled false

        }

    }

 

S3.gradle打包自動化-定制apk文件名

gradle屬性及變量定義的幾種方式

變量定義

方式1(for gradle)

工程目錄下gradle.properties定義屬性：appName = MyAppName

App目錄下build.gradle讀取自定義屬性：project.appName

方式2(for java)

App目錄下build.gradle定義屬性：

    productFlavors {

        aVer {

            // gradle定義全局變量方式2-代碼使用

            buildConfigField "int", "varInt", "0"

            buildConfigField "String", "varString", '"abc"'

        }

}

Java代碼讀取屬性：BuildConfig.varInt;BuildConfig.varString;

方式3(for java)

App目錄下build.gradle定義屬性：

    productFlavors {

        aVer {

            resValue("string","strKey","myKey")

        }

}

ava代碼讀取屬性：context.getString(R.string.strKey);

方式4

App目錄下build.gradle定義屬性：

def flavorName = "undefine"

def indexFlavor(String str) {

    return str.substring(0,str.length())

}

方式5

App目錄AndroidManifest.xml定義變量

        <meta-data

            android:name="env_key0"

            android:value="${env_val0}" />

build.gradle修改env_val0

    buildTypes {

        debug {

            minifyEnabled false

            manifestPlaceholders = [env_val0: "VAL0", env_val1: "VAL1"]

        }

    }

Java代碼中獲取meta屬性定義

    public static String getMetaValue(Context context,String key){

        ApplicationInfo applicationInfo = null;

        try {

            applicationInfo = context.getPackageManager().getApplicationInfo(context.getPackageName(), PackageManager.GET_META_DATA);

        } catch (PackageManager.NameNotFoundException e) {

            e.printStackTrace();

        }

        if (applicationInfo == null){

            return "";

        }

        return applicationInfo.metaData.getString(key);

    }

 

Ref:

     android studio gradle 多版本多apk打包（打包系列教程之五）

     Gradle 自定義構建全局變量

     android studio 自定義gradle變量

 

定制apk文件名

變量定義

自定義生成APK文件名

applicationVariants.all { variant ->

variant.outputs.each { output ->

def outputFile = output.outputFile

         // appName + version + createTime + svnVersion + flavor + buildType

         def fileName = "fileName.apk"

         output.outputFile = new File(outputFile.parent, fileName)

       }

    }

獲取相關屬性

AppName:自定義方式或getName()

Version:版本， defaultConfig.versionName

CreateTime:創建時間，new Date().format("yyyy-MM-dd", TimeZone.getTimeZone("UTC"))

SvnVersion :SVN提交版本號
Flavor :編譯渠道版本

BuildType:debug/beta/release版本

def fileName = "${project.appName}_v${defaultConfig.versionName}_${releaseTime()}_" +

                            "s${getSvnRevision()}_${indexFlavor(productFlavors.name)}_${getName()}.apk"

參考問題：

     buildTypes中加上signingConfig sigingConfigs.release運行就報錯

apply plugin: 'com.android.application'

    return new Date().format("yyyy-MM-dd", TimeZone.getTimeZone("UTC"))
}
def indexFlavor(String str) {
    return str.substring(0,str.length())
}
def getSvnRevision() { // for svn
    ISVNOptions options = SVNWCUtil.createDefaultOptions(true);
    SVNClientManager clientManager = SVNClientManager.newInstance(options);
    SVNStatusClient statusClient = clientManager.getStatusClient();
    SVNStatus status = statusClient.doStatus(projectDir, false);
    SVNRevision revision = status.getCommittedRevision();
    return revision.getNumber();
