proguard

1，在build.grandle添加，其中规则写在proguard-rules.pro中，也可以自定义一个文件，将其代替，比如eclipse常用的 proguard-project.txt: buildTypes { release { signingConfig signingConfigs.release minifyEnabled true # 设置是否进行 shrink 等操作（即无用代码压缩），一般设置为 true，使混淆更有效 proguardFiles getDefaultProguardFile(‘proguard-android.txt‘), ‘proguard-rules.pro‘ } } 2，在proguard-rules.pro中加入以下代码，基本可以涵盖所有 : -optimizationpasses 5 # 指定代码的压缩级别 -dontusemixedcaseclassnames # 是否使用大小写混合 -dontpreverify # 混淆时是否做预校验 -verbose # 混淆时是否记录日志 -optimizations !code/simplification/arithmetic,!field/*,!class/merging/* # 混淆时所采用的算法 -keep public class * extends android.app

What is the difference between these two proguard options? -keep class com.myclass.** -keep class com.myclass.** { *; } The first rule will only keep the classes themselves (and the default constructors). The second rule will also keep all methods and fields in the classes. -keep class com.myclass.** Preserve all classes in the com.myclass package and any sub-packages. Even if shrinking and optimization steps should alter the structure of or remove these classes, do not do so. -keep class com.myclass.** { *; } Preserve all classes in the com.myclass package as defined above as well as all

The following class describes a model I read from a .json file using Jackson 2.2 . public class Product { public String name; public int width; } The Gradle build process invokes ProGuard to shrink and obfuscate the release build. When I start the application the following error message occurs: com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "name" (class com.example.b.c), not marked as ignorable (0 known properties: ]) How can I configure ProGuard or annotate the Product class so that Jackson still works? I have to admin that I simplified the example in my

I imported an older project after a I installed the android SDK on a new computer. I am getting the following error in the "problems" window in eclipse. Obsolete proguard file; use -keepclasseswithmembers instead of -keepclasseswithmembernames proguard.cfg /MyApplication line 1 Here is the file. I tried replacing the -keepclasseswithmembernames in this file with -keepclasseswithmembers but it did not help. -optimizationpasses 5 -dontusemixedcaseclassnames -dontskipnonpubliclibraryclasses -dontpreverify -verbose -optimizations !code/simplification/arithmetic,!field/*,!class/merging/* -keep
