proguard Android minifyEnabled vrai + multidex = erreur

Question

Quand je commence mon application, j'ai beaucoup d'avertissements et d'erreurs:

Information:Gradle tasks [:app:assembleDebug] Warning:butterknife.compiler.ButterKnifeProcessor$IdScanner: can't find superclass or interface com.sun.tools.javac.tree.TreeScanner Warning:butterknife.compiler.ButterKnifeProcessor$RClassScanner: can't find superclass or interface com.sun.tools.javac.tree.TreeScanner Warning:butterknife.compiler.ButterKnifeProcessor$VarScanner: can't find superclass or interface com.sun.tools.javac.tree.TreeScanner Warning:org.apache.poi.hssf.usermodel.DummyGraphics2d: can't find superclass or interface java.awt.Graphics2D Warning:org.apache.poi.hssf.usermodel.EscherGraphics: can't find superclass or interface java.awt.Graphics Warning:org.apache.poi.hssf.usermodel.EscherGraphics2d: can't find superclass or interface java.awt.Graphics2D Warning:org.apache.poi.poifs.crypt.dsig.SignatureMarshalListener: can't find superclass or interface org.w3c.dom.events.EventListener Warning:org.apache.poi.xslf.usermodel.XSLFRenderingHint: can't find superclass or interface java.awt.RenderingHints$Key ....

Mes PROGARD règles est:

#BUTTERKNIFE 
# Retain generated class which implement ViewBinder. 
-keep public class * implements butterknife.internal.ViewBinder 

{ public(); }

# Prevent obfuscation of types which use ButterKnife annotations since the simple name 
# is used to reflectively look up the generated ViewBinder. 
-keep class butterknife.* 
-keepclasseswithmembernames class * { @butterknife.* <methods>; } 
-keepclasseswithmembernames class * { @butterknife.* <fields>; } 

Mon gradle:

buildTypes { release { 
      minifyEnabled true 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } } 

si je modifie minifyEnabled faux. Il n'y a pas d'erreurs J'utilise le mode multidex. Comment puis-je résoudre le problème?

Answer 1

Essayez cette ajouter cette ligne dans les dépendances de niveau app build.gradle

compilation 'com.android.support:multidex:1.0.1'

dexOptions { javaMaxHeapSize "4g" }

minifyEnabled faux

multiDexEnabled vrai
