android - 使用ProGuard会导致ACRA出现NoSuchFieldError

我在Android应用中使用ACRA 4.4.0来接收用户的崩溃报告。我的IDE是ADT Build:v22.2.1-833290。几天前，我开始将ProGuard用于要在Google Play上发布的应用程序。当我安装并启动导出的带签名的apk时，在ACRA报告中使用的字段会发生NoSuchFieldError。我的代码是:

@ReportsCrashes(formKey = <my_key>,
                mailTo = <my_email>,
                customReportContent = { ReportField.APP_VERSION_CODE, ReportField.APP_VERSION_NAME, ReportField.ANDROID_VERSION, ReportField.PHONE_MODEL, ReportField.CUSTOM_DATA, ReportField.STACK_TRACE, ReportField.LOGCAT },
                mode = ReportingInteractionMode.TOAST,
                resToastText = R.string.crash_toast_text)
public class MyApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        ACRA.init(this);
    }
}

在proguard-project.txt中包含“-keep public class org.acra。*”无效。正如我在GoogleDocs中看到的那样，可能的原因是Proguard无法与动态引用的字段和方法一起正常工作。优化的APK(不使用ACRA)效果很好。有没有办法解决这个问题？
提前致谢。

最佳答案

您可以尝试在此处使用其文档配置ACRA:https://github.com/ACRA/acra/wiki/Proguard在proguard配置文件中包括以下内容:

#ACRA specifics
# Restore some Source file names and restore approximate line numbers in the stack traces,
# otherwise the stack traces are pretty useless
-keepattributes SourceFile,LineNumberTable

# ACRA needs "annotations" so add this...
# Note: This may already be defined in the default "proguard-android-optimize.txt"
# file in the SDK. If it is, then you don't need to duplicate it. See your
# "project.properties" file to get the path to the default "proguard-android-optimize.txt".
-keepattributes *Annotation*

# 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);
}
