打包发布部分
S1.使用默认方式打包签名APK
AndroidStudio选择Build => Generate Signed APK
总体步骤流程如下：

详细操作步骤：

S2. 多渠道打包APK

属性配置

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\') // 签名证书文件
storePassword \'you password\' // 证书密码
keyAlias \'test\'
keyPassword \'you password \'
}
}

buildTypes

buildTypes {
mbeta {
signingConfig android.signingConfigs.release
minifyEnabled false
}
}

S3.gradle打包自动化-定制apk文件名
gradle属性及变量定义的几种方式

变量定义

方式1(for gradle)

工程目录下gradle.properties定义属性：appName = MyAppName
App目录下build.gradle读取自定义属性：project.appName

方式2(for java)

App目录下build.gradle定义属性：
productFlavors {
aVer {
// gradle定义全局变量方式2-代码使用
buildConfigField "int", "varInt", "0"
buildConfigField "String", "varString", \'"abc"\'
}
}
Java代码读取属性：BuildConfig.varInt; BuildConfig.varString;

方式3(for java)

App目录下build.gradle定义属性：
productFlavors {
aVer {
resValue("string","strKey","myKey")
}
}
ava代码读取属性：context.getString(R.string.strKey);

方式4

App目录下build.gradle定义属性：
def flavorName = "undefine"
def indexFlavor(String str) {
return str.substring(0,str.length())
}

方式5

App目录AndroidManifest.xml定义变量
< meta-data
android:name="env_key0"
android:value="https://www.songbingjia.com/android/${env_val0}" />
build.gradle修改env_val0
buildTypes {
debug {
minifyEnabled false
manifestPlaceholders = [env_val0: "VAL0", env_val1: "VAL1"]
}
}
Java代码中获取meta属性定义
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);
}

android studio 自定义gradle变量

定制apk文件名

变量定义

自定义生成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)
}
}

获取相关属性

AppName:自定义方式或getName()
Version:版本， defaultConfig.versionName
CreateTime:创建时间，new Date().format("yyyy-MM-dd", TimeZone.getTimeZone("UTC"))
SvnVersion :SVN提交版本号
Flavor :编译渠道版本
BuildType:debug/beta/release版本
def fileName = "${project.appName}_v${defaultConfig.versionName}_${releaseTime()}_" +
"s${getSvnRevision()}_${indexFlavor(productFlavors.name)}_${getName()}.apk"
