⑴ android-android怎麼實現只混淆自己的代碼，而不混淆第3方jar包
當項目中有第3方jar包時，怎麼實現混淆打包，而不對第3方包混淆
在項目中有第3方包時打包出錯日誌：

已經嘗試的方案：方案一： 加入-ignorewarnings 可以正常打包了。 能過濾掉警告信息。但是治標不治本，打好的包，在實際運行中用到過的第3方包類庫時，均報空指針。方案二：不使用-ignorewarnings 添加-dontwarn java.awt.datatransfer.Transferable.** 警告信息並沒有減少，打包會失敗。
⑵ Android Studio在真機上運行的APP啟動速度特別慢，而通過簽名打出的apk安裝後app速度卻很快怎麼回事
Android Studio提供debug和release兩種構建類型，默認採用debug類型調試Android項目，debug和release的區別有幾個方面：
debug模式的幾個特點：
1. 支持斷點調試和log信息列印，debuggable屬性值為true
2. 使用系統默認的密鑰庫簽署apk文件
3. 沒有對apk文件進行代碼和資源文件的優化（包括文件壓縮、冗餘文件刪除）
4. 沒有對代碼進行混淆
release模式需要注意的幾個特點：
1. 不支持斷點調試，debuggable默認為false
2. 沒有壓縮類文件代碼，minifyEnabled，默認為false
3. 沒有壓縮資源文件，shrinkResources，默認為false
4. 沒有指定自定義簽名文件，默認使用系統的密鑰庫簽署apk
真機上直接連接調試，因為沒有代碼、資源文件進行壓縮，同時支持斷點調試等原因造成運行緩慢；相反，簽名後的apk文件，相對來說比較快，可以深入理解Android Studio構建文件build.gradle配置相關資料
⑶ android 不混淆可以打包嗎
可以。
混淆打包流程：
1.在proguard-project.txt文件中添加不需要混淆的類和第三方的jar包
這個是保持自己包中不需要混淆的類，如果有些類調用了jni也不需要混淆，不然會出錯。還有如果項目中有其他項目作為library引入，那這些項目的一些類也不能混淆。
這個是保持項目中的第三方jar不混淆
另外加上上面幾句話，不然會在控制台中報warning警告
⑷ android studio怎麼混淆代碼
Android Studio上混淆打包apk方法：
//混淆,新版本是ninifyEnabled不再是runproguard
minifyEnabled true
//載入默認混淆配置文件及自定義混淆 配置
proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard.cfg'
設置minifyEnabled true,就會在打包的時候進行代碼混淆處理. 其中proguard-android.txt不用管，在sdk目錄裡面，主要是配置了proguard.cfg文件。
直接在android studio創建項目不會有這個文件，而是 proguard-rules.pro文件，其實一樣的，因為項目是從eclipse遷移過來的，之前在eclipse上混淆是 proguard.cfg文件.
