安卓 gradle代码混淆与打包

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     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);     }

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"
