J'utilise la dernière version du sdk 23 , c'est mon gradle fichier :

    apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion '23.0.0'
defaultConfig {
applicationId "com.x.x"
minSdkVersion 11
targetSdkVersion 23
}
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
dependencies {
compile 'com.android.support:appcompat-v7:23.0.0'
compile 'com.android.support:recyclerview-v7:23.0.0'
compile files('libs/acra-4.5.0.jar')
compile files('libs/universal-image-loader-1.8.4-with-sources.jar')
compile files('libs/org.apache.http.legacy.jar')
compile 'com.android.support:cardview-v7:23.0.0'
compile 'jp.wasabeef:recyclerview-animators:1.2.2'
compile 'com.android.support:design:23.0.0'
}

Quel est le problème ? où je n'allait pas dans ce code?

grâce

Je me demandais à propos de votre dépendance " compiler des fichiers('libs/org.apache.http.legacy.jar') ... si vous êtes en utilisant l'héritage apache lib, vous n'avez pas besoin du pot, vous avez juste besoin d'ajouter useLibrary 'org.apache.http.legacy'à votre android {} section.

android proguard

Il suffit d'ajouter ce sur proguard:
```
-keep class org.apache.http.** { *; }
-dontwarn org.apache.http.**
-dontwarn android.net.**
```
Bonne réponse, merci!
pouvez-vous nous expliquer comment ce travail que j'ai commencé à l'aide de proguard à partir d'aujourd'hui

J'ai juste ajouté ce sur proguard:
```
-ignorewarnings
-keep class * {
public private *; 
}
```
Et il est résolu ce problème.

Comme mentionné dans votre logcat vérifier http://proguard.sourceforge.net/manual/troubleshooting.html#duplicateclass

Vous avez des définitions de classe dans vos dépendances de l'application et c'est juste des avertissements.

Maintenant, Si vous voulez le corriger, veuillez ajouter le code ci-dessous dans votre proguard-android.txt:

# To enable ProGuard in your project, edit project.properties
# to define the proguard.config property as described in that file.
#
# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in ${sdk.dir}/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the ProGuard
# include property in project.properties.
#
# For more details, see
#   http://developer.android.com/guide/developing/tools/proguard.html
# Add any project specific keep options here:
# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
-dontwarn com.google.code.**
-dontwarn  org.apache.**
-dontwarn  jp.wasabeef.recyclerview.**
-dontwarn  com.nostra13.universalimageloader.**
-dontwarn  org.acra.** 
#wasabeef recyclerview
-keep class jp.wasabeef.recyclerview.** { *; }
-keepattributes Signature
#HTTP Legacy
-keep class org.apache.** { *; }
-keepattributes Signature
#Universal Image Loader
-keep class com.nostra13.universalimageloader.** { *; }
-keepattributes Signature
#Acra
-keep class org.acra.**  { *; }
-keepattributes Signature
#Support libraries
-keep class com.android.** { *; }
-keepattributes Signature
# Keep the annotations
-keepattributes *Annotation*
-allowaccessmodification
-keepattributes *Annotation*
-renamesourcefileattribute SourceFile
-keepattributes SourceFile,LineNumberTable
-repackageclasses ''
-dontnote com.android.vending.licensing.ILicensingService
# Explicitly preserve all serialization members. The Serializable interface
# is only a marker interface, so it wouldn't save them.
-keepclassmembers class * implements java.io.Serializable {
static final long serialVersionUID;
private static final java.io.ObjectStreamField[] serialPersistentFields;
private void writeObject(java.io.ObjectOutputStream);
private void readObject(java.io.ObjectInputStream);
java.lang.Object writeReplace();
java.lang.Object readResolve();
}
# Preserve all native method names and the names of their classes.
-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);
}
# Preserve static fields of inner classes of R classes that might be accessed
# through introspection.
-keepclassmembers class **.R$* {
public static <fields>;
}
# Preserve the special static methods that are required in all enumeration classes.
-keepclassmembers enum * {
public static **[] values();
public static ** valueOf(java.lang.String);
}
-keep public class * {
public protected *;
}
-keep class * implements android.os.Parcelable {
public static final android.os.Parcelable$Creator *;
}

Note : proguard-android.txt emplacement -> android-sdk-chemin\tools\proguard
