【Android】Android Studio 進行代碼混淆，打包release APK

標籤：

　　整了一天，感覺坑挺多。

1. 選擇中的選項Android Studio進行簽名打包：

 

 

 

 

 

 

 

 

 

2. 填寫APP對應的資訊：(最好用個文本記下來放在項目中同步給Team)

 - Key store path: 如果是新APP則建立，如果已經有了選擇就行；

 - Key store password: *******

 - Key alias（別名）: 自訂

 - 如果是新建立的檔案需要選擇時間，整個25年足夠用了，公司資訊填上就OK

 - 下一步後選擇release就開始打包

3. Android Studio的混淆功能需要在Gradle中添加：

apply plugin: ‘com.android.application‘android {    compileSdkVersion 19    buildToolsVersion ‘23.0.1‘    defaultConfig {        applicationId "com.rayclear.juchang"        minSdkVersion 17        targetSdkVersion 23        versionCode 4        versionName "1.03"    }    buildTypes {        release {            //代碼混淆開關，一定要注意現在已經使用minifyEnabled代替runProguard了            minifyEnabled true            // proguard-rules.pro 是當前使用的混淆檔案（Eclipse中的proguard.cfg)            proguardFiles getDefaultProguardFile(‘proguard-android.txt‘), ‘proguard-rules.pro‘        }    }    packagingOptions {        exclude ‘META-INF/DEPENDENCIES‘        exclude ‘META-INF/LICENSE‘        exclude ‘META-INF/LICENSE.txt‘        exclude ‘META-INF/license.txt‘        exclude ‘META-INF/NOTICE‘        exclude ‘META-INF/NOTICE.txt‘        exclude ‘META-INF/notice.txt‘        exclude ‘META-INF/ASL2.0‘    }    compileOptions {        sourceCompatibility JavaVersion.VERSION_1_7        targetCompatibility JavaVersion.VERSION_1_7    }}

4. 打包時遇到的問題：

1.一直處於Gradle Build Running...被坑了兩次，一直以為是真的在打包，IDE也木有個具體提示什麼的，就乾等了好久。遇到這種情況，直接關掉Android Studio重新開始吧。正常來說一個普通的APP打包混淆時間長度也就是1～3分鐘吧。2.關於cache.properties.lock的錯：Error:Timeout waiting to lock cp_proj class cache for build file ‘/Users/raomengyang/work/app/build.gradle‘ (/Users/raomengyang/.gradle/caches/2.8/scripts/build_aldsk0ke4ednnd4pf0nybqlhq/cp_proj). It is currently in use by another Gradle instance.Owner PID: unknownOur PID: 20080Owner Operation: unknownOur operation: Initialize cacheLock file: /Users/raomengyang/.gradle/caches/2.8/scripts/build_aldsk0ke4ednnd4pf0nybqlhq/cp_proj/cache.properties.lock之前遇到過同樣的情況，是將帶lock的檔案給恢複許可權解決的，可是這次不管用，於是退出AS重新來，每次遇到這個問題然後退出AS都會提示後台還有任務沒有結束，所以這個錯誤個人感覺是AS還有背景工作沒有被結束，以至於一直hold在這兒。3.各種specified twice：java.io.IOException: The same input jar [/Users/raomengyang/work/app/libs/**] is specified twice.刪掉proguard檔案中的重複聲明引用的jar檔案。4.滿天的Warning：Note: there were 157 duplicate class definitions.      (http://proguard.sourceforge.net/manual/troubleshooting.html#duplicateclass)Warning:library class org.apache.http.auth.AuthenticationException extends or implements program class org.apache.http.ProtocolExceptionWarning:library class org.apache.http.auth.MalformedChallengeException extends or implements program class org.apache.http.ProtocolExceptionWarning:library class org.apache.http.auth.params.AuthParamBean extends or implements program class org.apache.http.params.HttpAbstractParamBeanWarning:library class org.apache.http.client.NonRepeatableRequestException extends or implements program class org.apache.http.ProtocolExceptionWarning:library class org.apache.http.client.RedirectException extends or implements program class org.apache.http.ProtocolExceptionWarning:library class org.apache.http.client.entity.UrlEncodedFormEntity extends or implements program class org.apache.http.entity.StringEntityWarning:library class org.apache.http.client.methods.HttpEntityEnclosingRequestBase extends or implements program class org.apache.http.HttpEntityEnclosingRequestWarning:library class org.apache.http.client.methods.HttpRequestBase extends or implements program class org.apache.http.message.AbstractHttpMessageWarning:library class org.apache.http.client.methods.HttpUriRequest extends or implements program class org.apache.http.HttpRequestWarning:library class org.apache.http.client.params.AllClientPNames extends or implements program class org.apache.http.params.CoreConnectionPNames………………………………………………………………………………………………Warning……………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………Warning……………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………Warning……………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………Warning……………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………Warning……………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………Warning……………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………Warning……………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………Warning:library class org.apache.http.client.params.AllClientPNames extends or implements program class org.apache.http.params.CoreProtocolPNamesWarning:library class org.apache.http.client.params.ClientParamBean extends or implements program class org.apache.http.params.HttpAbstractParamBeanWarning:library class org.apache.http.client.protocol.RequestAddCookies extends or implements program class org.apache.http.HttpRequestInterceptorWarning:library class org.apache.http.client.protocol.RequestDefaultHeaders extends or implements program class org.apache.http.HttpRequestInterceptorWarning:library class org.apache.http.client.protocol.RequestProxyAuthentication extends or implements program class org.apache.http.HttpRequestInterceptor該類問題都可以根據我們的class檔案來進行以下聲明：例如：現在提示的是org.apache.http.* 這個包裡的類有問題，那麼就加入下述代碼：-keep class org.apache.http.** { *; }-dontwarn org.apache.http.**依此類推，注意一點，混淆完後，就算打包成功也需要再次測試，因為APP內部可能會出現上述問題。
