java - Android ACRA 和 ProGuard

Question

在 ACRA 网站上有一个关于在 Eclipse 中使用 ACRA 和 ProGuard 的指南:https://github.com/ACRA/acra/wiki/ProGuard

就我而言，我使用 Android Studio，我不是 java 专家，但是我需要将 ACRA 支持添加到我的应用程序中。我刚刚编辑了我的项目，但我不明白如何在 Android Studio 中设置 ProGuard 来与 ACRA 一起使用，因此在我的发布应用程序中 ACRA 不起作用。

您能解释一下如何将 Eclipse 步骤“转换”为 Android Studio 步骤吗？

Answer 1

您是否有现有的 Eclipse 项目并希望将其导入到 Android Studio 中？

如果没有，解决方案如下:

您的 build.gradle(位于“app”文件夹中)文件应如下所示:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 20
    buildToolsVersion '20.0.0'

    defaultConfig {
        applicationId "com.yourapp"
        minSdkVersion 14
        targetSdkVersion 20
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard true//make this true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile project(':library')
    compile 'ch.acra:acra:4.5.0'//add this line here
}

和你的 proguard-rules.pro:

# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in C:\Android\AndroidSDKBundle2014-03-21x64\sdk/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the proguardFiles
# directive in build.gradle.
#
# For more details, see
#   http://developer.android.com/guide/developing/tools/proguard.html

# Add any project specific keep options here:

# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
#class:
-keepclassmembers class fqcn.of.javascript.interface.for.webview {
   public *;
}


#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);
}

其余的就像 eclipse 一样。
