解決辦法：因?yàn)椴捎昧巳降膉ar包，需要我們?cè)?proguard.cfg 中添加"-dontwarn"

如下：

proguard.cfg 全部配置

-dontwarn 

-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 ;

}

-keepclasseswithmembers class * {

    public (android.content.Context, android.util.AttributeSet);

}

-keepclasseswithmembers class * {

    public (android.content.Context, android.util.AttributeSet, int);

}

-keepclassmembers class * extends android.app.Activity {

   public void *(android.view.View);

}

-keepclassmembers enum * {

    public static **[] values();

    public static ** valueOf(java.lang.String);

}

-keep class * implements android.os.Parcelable {

  public static final android.os.Parcelable$Creator *;

}

可解決！
