Android SDK (r20 이상)
project.properties에 참조 된 사전 정의 된 proguard.config를 확인하십시오.
proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt
추가 정보 : http://proguard.sourceforge.net/manual/examples.html#androidapplication
Gradle에서 :
buildTypes {
release {
minifyEnabled true
shrinkResources true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
...
}
}
여기에서 내가 계속 업데이트하는 proguard "기본"파일을 확인할 수 있습니다. https://medium.com/code-procedure-and-rants/android-my-standard-proguard-ffeceaf65521
Android SDK (r19 이하)
default.properties에 추가 할 수 있습니다. 지금까지 문제없이 수동으로 추가했습니다.
라인을 추가하는 경우 :
proguard.config=proguard.cfg
말했듯이 서명 된 애플리케이션을 내보낼 때만 ProGuard를 사용합니다 (Android 도구 => 서명 된 애플리케이션 내보내기).
Android 2.3 이전에 SDK로 프로젝트를 시작하면 proguard.cfg파일이 생성되지 않습니다 ( default.properties2.3>과 같이 옆에 있음).
자동 생성을 사용하려면 Android 2.3의 SDK로 업데이트하고 기존 소스 (현재 보유한 프로젝트의 소스)로 새 프로젝트를 생성하면됩니다.
자동으로 proguard.cfg채우기가 생성됩니다.
그래도 수동으로 만들려면 다음을 포함해야합니다.
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontwarn android.support.**
-verbose
-dontoptimize
-dontpreverify
-keepattributes *Annotation*
-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 * extends android.support.v4.app.Fragment

-keepclasseswithmembernames class * {

}
-keepclasseswithmembernames class * {

}
-keepclasseswithmembernames class * {
public <init>(android.content.Context, android.util.AttributeSet, int);
}
-keepclassmembers public class * extends android.view.View {
void set*(***);
*** get*();
}
-keepclassmembers enum * {
public static **[] values();
public static ** valueOf(java.lang.String);
}
-keep class * implements android.os.Parcelable {
public static final android.os.Parcelable$Creator *;
}
-keepclassmembers class **.R$* {
public static <fields>;
}
위의 모든 질문에 답한 것 같습니다.

라인 별 설명 :
#Use 5 step of optimization
#-optimizationpasses 5
#When not preverifing in a case-insensitive filing system, such as Windows. This tool will unpack your processed jars,(if using windows you should then use):
-dontusemixedcaseclassnames
#Specifies not to ignore non-public library classes. As of version 4.5, this is the default setting
-dontskipnonpubliclibraryclasses
# Optimization is turned off by default. Dex does not like code run
# through the ProGuard optimize and preverify steps (and performs some
# of these optimizations on its own).
-dontoptimize
-dontpreverify
-dontwarn android.support.**
#Specifies to write out some more information during processing. If the program terminates with an exception, this option will print out the entire stack trace, instead of just the exception message.
-verbose
#The -optimizations option disables some arithmetic simplifications that Dalvik 1.0 and 1.5 can't handle. Note that the Dalvik VM also can't handle aggressive overloading (of static fields).
#To understand or change this check http://proguard.sourceforge.net/index.html#/manual/optimizations.html
#-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*
# Note that if you want to enable optimization, you cannot just
# include optimization flags in your own project configuration file;
# instead you will need to point to the
# "proguard-android-optimize.txt" file instead of this one from your
# project.properties file.
#To repackage classes on a single package
#-repackageclasses ''
#Uncomment if using annotations to keep them.
