android 程序代碼混淆 proguard 腳本 proguard.cfg

android 代碼混淆

1 proguard.cfg,這就是混淆所需的proguard腳本啊。

 

其代碼如下:

 

[java]  

view plain  

-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 *;   

}   

 

從腳本中可以看到,混淆中保留瞭繼承自Activity、Service、Application、BroadcastReceiver、ContentProvider等基本組件。

並保留瞭所有的Native變量名及類名,所有類中部分以設定瞭固定參數格式的構造函數,枚舉等等。(詳細信息請參考<proguard_path>/examples中的例子及註釋。)

2 在工程的"default.properties"中添加這樣一句話“proguard.config=proguard.cfg”

 

 

打包簽名後的.apk就是混淆的,其實我們隻要做一步就可以瞭就是在"default.properties"中添加這樣一句話“proguard.config=proguard.cfg”就可以瞭。

 

出現錯誤:

[INFO] Warning: there were 294 unresolved references to classes or interfaces.

[INFO]          You may need to specify additional library jars (using '-library

jars').

[INFO] Warning: there were 3 unresolved references to program class members.

      You should consider explicitly keeping the mentioned class members

      (using '-keep' or '-keepclassmembers').

[INFO]          Your input classes appear to be inconsistent.

[INFO]          You may need to recompile them and try again.

[INFO]          Alternatively, you may have to specify the option

[INFO]          '-dontskipnonpubliclibraryclassmembers'.

[INFO] java.io.IOException: Please correct the above warnings first.

[INFO]  at proguard.Initializer.execute(Initializer.java:321)

[INFO]  at proguard.ProGuard.initialize(ProGuard.java:211)

[INFO]  at proguard.ProGuard.execute(ProGuard.java:86)

[INFO]  at proguard.ProGuard.main(ProGuard.java:492)

解決方法如下:解決方法找到瞭,在proguard.cfg文件中加入-ignorewarnings就可以跳過這個錯誤瞭。
