Android obfuscate app using proguard keep obfuscating library bars - or is?
Je suis novice dans l'utilisation de Proguard, donc je fais probablement une erreur de débutant. J'ai une application qui, après avoir exécuté la version (qui utilise Proguard pour masquer), se bloque assez rapidement. Je crois que je l'ai réduit au fait qu'il semble qu'il obscurcit mes bibliothèques de référence. Dans mon cas, mes bibliothèques de référence sont utilisées pour définir mes classes de messages que j'utilise pour communiquer avec un autre appareil à l'aide de Google Protobuffers. Je construis en utilisant, libération de fourmis. Ma configuration proguard est:
-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 * extends Android.app.backup.BackupAgentHelper
-keep public class * extends Android.preference.Preference
-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 *;
}
Dans mon fichier ant build.xml, j'ai défini les éléments suivants:

J'apprécierais toutes les idées. J'ai copié la plupart de ma configuration et de ma configuration proguard à partir de modèles en ligne, je soupçonne que j'intrigue réellement Proguard pour obscurcir les pots de la bibliothèque ou j'ai quelque chose de mal configuré. Je vois la sortie suivante dans ma fenêtre cmd à la fin de la construction:
[proguard] Writing output...

[proguard] Copying resources from program jar [C:\Workspace\UI\MyApp\build\proguard\original.jar]

Merci!
Vous avez commenté vos directives jar de bibliothèque dans la configuration Proguard.
Changement:
# -libraryjars /libs/protobuf-2.3.0.jar
# -libraryjars /libs/libmessaging.jar
à:
-libraryjars /libs/protobuf-2.3.0.jar
-libraryjars /libs/libmessaging.jar
(et puis ne vous embêtez pas à définir vos pots de bibliothèque dans votre build.xml)
ÉDITER:
.
-keep class javax.** { *; }
-keep class org.** { *; }
-keep class Twitter4j.** { *; }
J'ai rencontré un problème similaire lorsque proGuard a chiffré la bibliothèque jsoup. Je l'ai corrigé en ajoutant ce qui suit à mon proguard-rules.txt:
-keep class org.jsoup** {
*;
}
Ainsi, build.gradle se terminera par la section suivante:
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-Android.txt'), 'proguard-rules.txt'
}
