Android 警告 - 忽略 InnerClasses 属性(jnamed)

Question

我在 Android Studio 中构建代码时收到此警告。
它们很少会不显示，但大多数时候会显示。

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.

我已经阅读了其他问题并将它们包含在我的混淆文件中:

-keepattributes EnclosingMethod
-keepattributes InnerClasses

但是他们没有帮助。

编辑:

如果无法解决这个问题，请告诉我如何在 postguard 中隐藏此警告(或任何其他方式)。谢谢!

是什么导致了这个问题？

您正在尝试在运行 Android 运行时 Dalvik 的 JVM 中使用未针对 Java 6 或 7 编译的类文件。这不是什么大问题，您不必担心。

我该如何解决？

您可以重新编译导致问题的库。不幸的是，该库已经在编译的 jar 中。你可以尝试在网上寻找它的源码然后编译它
