android - 发布构建 apk 文件

Question

我正在使用一个应用程序，我在我的应用程序的 build.gradle 文件中启用了 runProguard true。当我去构建签名的 apk 时，我收到警告并且构建过程失败。

我想我终于想通了!

梯度依赖:

dependencies {
    ...
    compile 'com.google.guava:guava:18.0'
    /* Required for using guava with proguard */
    compile 'javax.annotation:jsr250-api:1.0'
}

添加到我的混淆器配置中:

##-------------Begin Settings For Guava ------------------------------------------------------------
#https://github.com/krschultz/android-proguard-snippets/blob/master/libraries/proguard-guava.pro
# Configuration for Guava
#
# disagrees with instructions provided by Guava project: https://code.google.com/p/guava-libraries/wiki/UsingProGuardWithGuava
#
# works if you add the following line to the Gradle dependencies
#
# provided 'javax.annotation:jsr250-api:1.0'
-keep class com.google.common.io.Resources {
    public static <methods>;
}
-keep class com.google.common.collect.Lists {
    public static ** reverse(**);
}
-keep class com.google.common.base.Charsets {
    public static <fields>;
}

-keep class com.google.common.base.Joiner {
    public static Joiner on(String);
    public ** join(...);
}

-keep class com.google.common.collect.MapMakerInternalMap$ReferenceEntry
-keep class com.google.common.cache.LocalCache$ReferenceEntry

-dontwarn sun.misc.Unsafe
-dontwarn javax.annotation.**
