Android 渐变生成失败，shrinkResources=true

我无法生成shrinkResources=true的签名apk。也附上我的proguard-rules.pro。我在stackoveflow中发现了很多东西，但是没有详细的内容来完美地解决我的问题。任何特定/正确的解决方案

# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in /Users/comviva/Library/Android/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 *;
#}

启用minifyEnabled以使用快照代码下方的shrinkResources

android {
buildTypes {
    release {
        shrinkResources true
        minifyEnabled true     // <---- here
        proguardFiles getDefaultProguardFile('proguard-android.txt'),
                'proguard-rules.pro'
    }
}
...

android{
建筑类型{
释放{
真的吗
minifyEnabled true//
android {
buildTypes {
    release {
        shrinkResources true
        minifyEnabled true     // <---- here
        proguardFiles getDefaultProguardFile('proguard-android.txt'),
                'proguard-rules.pro'
    }
