Android警告 - 忽略InnerClasses屬性（jnamed）

Question

我在Android Studio中構建我的代碼時遇到此警告。
幾次他們沒有出現，但他們大多數時間。

warning: Ignoring InnerClasses attribute for an anonymous inner class 
(jnamed$1) that doesn't come with an 
associated EnclosingMethod attribute. This class was probably produced by a 
compiler that did not target the modern .class file format. The recommended 
solution is to recompile the class from source, using an up-to-date compiler 
and without specifying any "-target" type options. The consequence of ignoring 
this warning is that reflective operations on this class will incorrectly 
indicate that it is *not* an inner class. 
warning: Ignoring InnerClasses attribute for an anonymous inner class 
(jnamed$2) that doesn't come with an 
associated EnclosingMethod attribute. This class was probably produced by a 
compiler that did not target the modern .class file format. The recommended 
solution is to recompile the class from source, using an up-to-date compiler 
and without specifying any "-target" type options. The consequence of ignoring 
this warning is that reflective operations on this class will incorrectly 
indicate that it is *not* an inner class. 
warning: Ignoring InnerClasses attribute for an anonymous inner class 
(jnamed$3) that doesn't come with an 
associated EnclosingMethod attribute. This class was probably produced by a 
compiler that did not target the modern .class file format. The recommended 
solution is to recompile the class from source, using an up-to-date compiler 
and without specifying any "-target" type options. The consequence of ignoring 
this warning is that reflective operations on this class will incorrectly 
indicate that it is *not* an inner class. 

我讀過的其他問題，其中包括這些在我的ProGuard文件：

-keepattributes EnclosingMethod 
-keepattributes InnerClasses 

但是他們並沒有幫助。

編輯：

如果這是不可能解決這個問題，請告訴我如何隱藏在postguard此警告（或任何其他方式）。謝謝！

Answer 1

Whats cause the problem？

您正嘗試在運行Android運行時Dalvik的JVM中使用未針對Java 6或7編譯的類文件。這不是一個大問題，你不必擔心。

我該如何解決？

您可以重新編譯導致問題的庫。不幸的是，該庫已經在編譯的jar中。您可以嘗試在線查找源代碼，然後編譯該代碼

Answer 2

您是否考慮過更新JDK和JRE？此外，你有沒有更新Android工作室到最新版本？執行這些任務可能會解決問題。在sdk管理器中卸載並重新安裝proguard可能會有所幫助。
