我最近将我的 Android 项目从 Eclipse 迁移到了 Android Studio。
Android Studio 创建的调试版应用在设备上运行良好，但发布版在启动时崩溃。
这是我的应用程序的 build.gradle 文件:
apply plugin: 'com.android.application'

buildToolsVersion "23.0.2"
defaultConfig {

}

}

这是我的 proguard-rules.pro 文件:

01-06 11:48:58.503 1038-1476/? W/ActivityManager: Force finishing activity com.example.myapp/.SplashActivity
看来我在 proguard-rules.pro 文件中指定的 keep 规则没有被用作 com.example.myapp.SplashActivity 找不到类。
我检查了 Android Developers ProGuard页面，看起来我已经正确设置了所有内容，所以我不知道为什么它不起作用。
任何人都可以建议我需要做什么才能最终得到一个有效的混淆 apk 吗？
最佳答案
我发现了问题。它在我项目的 build.gradle 文件中:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter() // This is the default repo
mavenCentral() // This is the Maven Central repo
}
dependencies {
classpath 'com.android.tools.build:gradle:1.3.0'
classpath 'com.google.gms:google-services:1.5.0-beta2'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter() // This is the default repo
mavenCentral() // This is the Maven Central repo
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
解决方案是将 classpath 'com.android.tools.build:gradle:1.3.0' 更改为 classpath 'com.android.tools.build:gradle:1.5。 0'.
(我通过创建一个新的测试项目并比较各个 build.gradle 文件中的值发现了这一点。)
顺便说一句，我的 proguard-rules.pro 文件的内容现在只是...
#
# Twitter - start
#
-dontwarn twitter4j.**
-keep class twitter4j.** { *; }
#
# Twitter - end
#
#
# Support library / ShareActionProvider - start
#

-keep interface android.support.v7.internal.** { *; }
-keep class android.support.v7.** { *; }
-keep interface android.support.v7.** { *; }
#
# Support library / ShareActionProvider - start
#
#
# ACRA - start
#
#ACRA specifics
# Restore some Source file names and restore approximate line numbers in the stack traces,

-keepattributes SourceFile,LineNumberTable

-keepattributes *Annotation*
# keep this class so that logging will show 'ACRA' and not a obfuscated name like 'a'.

-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);
}
#
# ACRA - end
#
...所以我不需要很多旧指令或 Dhawal 在他的回答中建议的指令。
注意 - 我了解从 ACRA 4.8 开始不再需要 ACRA 指令。
