android 通過添加proguard.cfg檔案實現代碼混淆

標籤：android   style   blog   class   code   java   

若項目中沒有proguard.cfg檔案，手動添加

建立文本，輸入以下代碼

-dontwarn  //若項目中匯入了第三方jar包，需要添加該行-optimizationpasses 5-dontusemixedcaseclassnames-dontskipnonpubliclibraryclasses-dontpreverify-verbose-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*-keep public class * extends android.app.Activity-keep public class * extends android.app.Application-keep public class * extends android.app.Service-keep public class * extends android.content.BroadcastReceiver-keep public class * extends android.content.ContentProvider-keep public class com.android.vending.licensing.ILicensingService-keepclasseswithmembernames class * {native <methods>;}-keepclasseswithmembernames class * {public <init>(android.content.Context, android.util.AttributeSet);}-keepclasseswithmembernames class * {public <init>(android.content.Context, android.util.AttributeSet, int);}-keepclassmembers enum * {public static **[] values();public static ** valueOf(java.lang.String);}-keep class * implements android.os.Parcelable {public static final android.os.Parcelable$Creator *;}

重新命名文本為proguard.cfg

將該檔案複製到項目中，與AndroidManifest.xml檔案在同一層

 

開啟project.properties檔案，添加以下內容

proguard.config=proguard.cfg

 

儲存，右擊項目名->Android-Tools->Export Unsigned Application Package

產生項目apk，混淆完成

 

若該過程中報 java.io.IOException: Please correct the above warnings這個錯誤，可能是忘記在proguard.cfg中添加  -dontwarn  添加後重試。
