Question

当我启动应用程序时，我会收到很多警告和错误：

信息：Gradle任务[：app：assembleDebug] 警告：butterknife.compiler.ButterKnifeProcessor $ IdScanner：不能找到超类或接口com.sun.tools.javac.tree.TreeScanner 警告：butterknife.compiler.ButterKnifeProcessor $ RClassScanner：不能找到超类或接口com.sun.tools.javac.tree.TreeScanner 警告：butterknife.compiler.ButterKnifeProcessor $ VarScanner：不能找到超类或接口com.sun.tools.javac.tree.TreeScanner 警告：org.apache.poi.hssf.usermodel.DummyGraphics2d：找不到超类或接口java.awt.Graphics2D 警告：org.apache.poi.hssf.usermodel.EscherGraphics：找不到超类或接口java.awt.Graphics 警告：org.apache.poi.hssf.usermodel.EscherGraphics2d：找不到超类或接口java.awt.Graphics2D 警告：org.apache.poi.poifs.crypt.dsig.SignatureMarshalListener：找不到超类或接口org.w3c.dom.events.EventListener 警告：org.apache.poi.xslf.usermodel.XSLFRenderingHint：找不到超类或接口java.awt.RenderingHints $ Key .... 错误：任务＆gt;'：app：transformClassesAndResourcesWithProguardForDebug'的执行失败。作业失败，请参阅日志了解详情

我的计划规则是：

# Workaround for ProGuard not recognizing dontobfuscate
-dontobfuscate
-dontoptimize
-optimizations !code/allocation/variable
#Rules for javascript and webview
-keepclassmembers class fqcn.of.javascript.interface.for.webview {
   public *;
}
-keepattributes *Annotation*,EnclosingMethod,Signature
#Parcel
-keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}
-keep class org.parceler.Parceler$$Parcels
-keep public class org.apache.poi.** {*;}
#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>; }

我的傻瓜：

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

如果我改变minifyEnabled false。没有错误。我正在使用multidex模式。我该如何解决这个问题？

Answer 1

试试这个在build.gradle应用程序级别依赖项中添加此行

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

dexOptions { javaMaxHeapSize“4g” }

minifyEnabled false

multiDexEnabled true

Android proguard minifyEnabled true + multidex = error
