我使用下面的代码显然根据产品口味自动生成pro guard映射文件.
buildTypes {
release {
minifyEnabled true
shrinkResources true
proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard-rules.pro'
applicationVariants.all { variant ->
if (variant.getBuildType().isMinifyEnabled()) {
variant.assemble.doLast {
copy {
from variant.mappingFile
into "${rootDir}/proguardTools"
rename { String fileName ->
"mapping-${variant.name}.txt"
}
}
}
}
}
}
}
将android studio升级到3.0后,它会显示一条警告,提示isMinifyEnabled()已弃用,我无法找到任何解决方案或替代此isMinifyEnabled().有任何帮助提前感谢吗？
解决方法
来自Android Gradle Plugin 3.0的
sources：
/**
* Returns whether minification is enabled for this build type.
*
* @return true if minification is enabled.
* @deprecated remember that this flag means that some "ProGuard-like" tool has run,it does not
* say if the tool was used to obfuscate and/or minify. In build system code this
* information is available elsewhere and should be used instead of this method.
*/
@Deprecated
boolean isMinifyEnabled();
此文档含糊不清,并不直接告诉您要使用的内容.
在blame中,我们可以看到,已经执行了这些更改的Michał Bendowski,我已经请求帮助了question in twitter.这是回复：
另外我在latest commit中看不到@Deprecated注释(在写这篇文章的时候是android-8.0.0_r34),这意味着API不会在那里被弃用.
作为修复,您可以在if语句之前禁止将此行放入警告：
//noinspection GrDeprecatedAPIUsage
if (variant.getBuildType().isMinifyEnabled()) {
...
}
