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="${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     pu blic 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); }

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"

参考问题：

     buildTypes中加上signingConfig sigingConfigs.release运行就报错

build.gradle多渠道打包完整示例

// app/build.gradle文件
import org.tmatesoft.svn.core.wc.* // for svn version
apply plugin: 'com.android.application'
def releaseTime() {
    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();
