和proguard-rules.pro

# Add project specific ProGuard rules here.
# By defaulto, the flags in this file are appended to flags specified
# in C:\Users\CM\AppData\Local\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 *;
#}

-keep class io.codetail.animation.arcanimator.** { *; }
-keep public class * implements com.bumptech.glide.module.GlideModule
-keep public class * extends com.bumptech.glide.AppGlideModule
-keep public enum com.bumptech.glide.load.resource.bitmap.ImageHeaderParser$** {
  **[] $VALUES;
  public *;
}

如何修改文件以解决此问题？

更改

buildTypes->debug->minifyEnabled=false

删除

multiDexEnabled true

，

shrinkResources true

，

useProguard false

将

minifyEnabled true

更改为

minifyEnabled false

希望这有帮助

您需要在

proguard rules.pro

中向所有第三方库添加-dontwarn或-ignorewarnings。您可以在them@StanislavBondar你能举例说明如何用proguard写这个吗？在您可以在此处找到解决方案之前，我没有使用过此选项：
