我正在尝试构建一个启用了proguard的发布apk。我收到以下错误。我将在下面附上完整的堆栈跟踪。
Unexpected error while evaluating instruction:
Class = [*]
Method = [myMethod(Ljava/lang/String;Ljava/util/Map;)V]
Instruction = [532] aload_3 v3
Exception = [java.lang.IllegalArgumentException] (Value is not a reference value [proguard.evaluation.value.UnknownIntegerValue])
Unexpected error while performing partial evaluation:
Class = [*]
Method = [myMethod(Ljava/lang/String;Ljava/util/Map;)V]
Exception = [java.lang.IllegalArgumentException] (Value is not a reference value [proguard.evaluation.value.UnknownIntegerValue])
:*:proguardRelease FAILED
我已将问题缩小到堆栈跟踪中未提及的代码行。
RelativeLayout.LayoutParams relativeLayoutParams = new RelativeLayout.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
如果我要对此进行评论，那么proguard会毫无问题地完成。
我目前已将proguard升级到新5.0，但它没有效果。
我做错了吗？

这可能是ProGuard优化枚举类型的一个错误。您可以通过禁用此优化来解决此问题：
-optimizations !class/unboxing/enum
如果您可以提交错误报告或向我发送详细信息，我会调查一下。

奇怪的解决方案，但我找到了解决问题的方法。导致proguard问题的代码的确切部分被分离为一个不同的方法，并在旧位置调用该方法。这似乎已经解决了问题，即使我不确定它是如何解决的。它似乎越来越像Proguard bug。它对我有用，所以如果遇到这个问题，其他人可以尝试。
