应用程序崩溃时生成带有混淆的签名apk(NoSuchMethodError)

我正面临这个特殊的问题,我的应用程序在生成带有混淆(progaurd)的已签名apk时会立即崩溃.我的progaurd如下所示:

-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.view.View {
public (android.content.Context);
public (android.content.Context, android.util.AttributeSet);
public (android.content.Context, android.util.AttributeSet, int);
public void set*(...);
}

-keepclasseswithmembers class * {
 public (android.content.Context, android.util.AttributeSet);
 }

 -keepclasseswithmembers class * {
 public (android.content.Context, android.util.AttributeSet, int);
 }

-keepclassmembers class * extends android.content.Context {
 public void *(android.view.View);
 public void *(android.view.MenuItem);
 }

-keepclassmembers class * implements android.os.Parcelable {
 static ** CREATOR;
 }

-keepclassmembers class **.R$* {
public static ;
 }


 -keepattributes Exceptions,InnerClasses,Signature

  -keep class com.google.api.client.**
  -keepclassmembers class com.google.api.client.** {
  *;
   }


 -keep class com.google.android.gms.**
 -keepclassmembers class com.google.android.gms.** {
 *;
  }
 -keep class com.google.gson.**
 -keepclassmembers class com.google.gson.** {

 }



-keep class com.google.api.client.** { *; }
-dontwarn com.google.api.client.*
-keep class org.apache.http.** { *; }
-dontwarn org.apache.http.*

-dontnote org.apache.http.**

-keep class android.support.v4.** { *; }
-keepclassmembers class android.support.v4.** {

 -keep interface android.support.v4.** { *; }
 -keep class android.support.v7.** { *; }


-keepclassmembers class android.support.v7.** {

-keep interface android.support.v7.** { *; }

-keep class org.apache.http.** { *; }
-keepclassmembers class org.apache.http.** {*;}
-dontwarn org.apache.**


-keep class org.codehaus.mojo.animal_sniffer.** { *; }
-keep class java.nio.file.** { *; }
-keep class java.lang.invoke.** { *; }

-keepclassmembers class com.fasterxml.jackson.core.**

-keepclassmembers class org.codehaus.mojo.animal_sniffer.**
-keepclassmembers class java.nio.file.**
-keepclassmembers class java.lang.invoke.**
-enter code here`-dontwarn retrofit2.**
-keep class retrofit2.** { *; }
-keepclasseswithmembers class * {
@retrofit2.http.* ;
}

-keep class android.net.http.** { *; }
-keepclassmembers class android.net.http.** {*;}
-dontwarn android.net.**

我能够生成签名的apk但如果启动此应用程序,应用程序崩溃会抛出以下错误:

java.lang.NoSuchMethodError: No interface method i()I in class 
Landroid/content/res/XmlResourceParser; or its super classes (declaration of 
'android.content.res.XmlResourceParser' appears in

任何人都可以建议我是否遗漏了progaurd文件或任何其他配置中的任何内容(在构建.gradle我已经提到minifyEnabled true以及proguard路径).

你可以使用jar包中包含XmlPullParser类,所以添加这个可以解决它.

-keep class org.xmlpull.v1.** { *;} -dontwarn org.xmlpull.v1.**
