dexguard 混淆问题

Question

我正在使用 dexguard 来混淆我的应用程序，但是当我这样做时，我在运行应用程序时遇到了崩溃。下面是堆栈跟踪。

这是我从 ACRA lib init 方法中得到的，因为我们在其中有 getAnnotation 方法。我用过-keepattributes *Annotation* 和-keep class org.acra.ACRA {*;}

但运气不好……

有人知道吗？

谢谢，

您可能不需要混淆 ACRA 代码，因为它不是秘密库。所以你可以这样做：

# Keep all the ACRA classes
-keep class org.acra.** { *; }

或者，如果您非常特别，您可以尝试使用：https://github.com/ACRA/acra/wiki/Proguard 在配置文件中包含以下内容来配置 ACRA：

# keep this class so that logging will show 'ACRA' and not a obfuscated name like 'a'.
# Note: if you are removing log messages elsewhere in this file then this isn't necessary
-keep class org.acra.ACRA {
    *;
}

# keep this around for some enums that ACRA needs
-keep class org.acra.ReportingInteractionMode {
    *;
}

-keepnames class org.acra.sender.HttpSender$** {
    *;
}

-keepnames class org.acra.ReportField {
    *;
}

# keep this otherwise it is removed by ProGuard
-keep public class org.acra.ErrorReporter
{
    public void addCustomData(java.lang.String,java.lang.String);
    public void putCustomData(java.lang.String,java.lang.String);
    public void removeCustomData(java.lang.String);
}

# keep this otherwise it is removed by ProGuard
-keep public class org.acra.ErrorReporter
{
    public void handleSilentException(java.lang.Throwable);
}
