我正在使用 Proguard 来混淆 Android 应用程序。一切正常，但我正在努力从错误报告中追溯堆栈跟踪。
这是我的混淆代码的摘录：
private ez a(x paramx)
{
return (ez)this.J.get(paramx);
}
private void a(com.b.a.f paramf)
{
Iterator localIterator = this.K.iterator();
while (true)
{
if (!localIterator.hasNext())
return;
em localem = (em)localIterator.next();
if (localem.a((int)(this.i / this.m - 202.0F), (int)(202.0F + (this.i + this.n) / this.m), (int)(this.j / this.m - 202.0F), (int)(202.0F + (this.j + this.o) / this.m)))
localem.a(paramf, this.m, this.i, this.j);
}
}
private void a(com.b.a.f paramf, int paramInt1, int paramInt2, int paramInt3, int paramInt4)
{
Iterator localIterator = this.J.entrySet().iterator();
while (true)
{
if (!localIterator.hasNext())
return;
ez localez = (ez)((Map.Entry)localIterator.next()).getValue();
if (localez.a(paramInt1, paramInt2, paramInt3, paramInt4))
localez.a(paramf, this.k, this.m, this.i, this.j);
}
}
您会注意到上述所有 3 个方法（取自同一个类）具有相同的名称 = 'a'。当然这在运行时不会造成问题，因为它们有不同的参数。但是在我混淆的堆栈跟踪中：
java.lang.ArrayIndexOutOfBoundsException: length=0; index=0

这是个问题。我不知道它指的是哪个“a”方法。当我使用retrace.bat 时，它会列出所有名为“a”的方法。
这是我的 proguard.config：

-dontskipnonpubliclibraryclasses
-dontpreverify
-dontwarn android.support.**

##---------------Begin: proguard configuration for Gson ----------
# Gson uses generic type information stored in a class file when working with
#fields. Proguard removes such information by default, so configure it to keep
#all of it.
-keepattributes Signature
# For using GSON @Expose annotation
-keepattributes *Annotation*
# Gson specific classes
-keep class sun.misc.Unsafe { *; }
#-keep class com.google.gson.stream.** { *; }
# Application classes that will be serialized/deserialized over Gson
-keep class com.gameanalytics.android.** { *; }
##---------------End: proguard configuration for Gson ----------
这是非常典型的，除了我在最后添加了一些内容来帮助支持我对 JSON/GSON 的使用。
我可以添加一个选项来强制 proguard 给每个方法一个不同的名称吗？
