我正在使用 android studio 3.1.3， 在使用 proguard 生成签名 apk 时出现以下错误

我已将我的代码和错误放在以下链接中

还有我的proguard文件

【问题讨论】：

发布完整的日志和您的 proguard 文件 - 您在此处发布的内容没有错误。通常你可以安全地忽略 proguard 问题来构建签名的 apk - 但你需要在文件中抑制它们

在您发布您的 proguard 文件后查看我编辑的答案。

【参考方案1】：

将此代码放入您的 progard 文件中

 # Proguard Configuration for Realm (http://realm.io)
    # For detailed discussion see: https://groups.google.com/forum/#!topic/realm-java/umqKCc50JGU
    # Additionally you need to keep your Realm Model classes as well
    # For example:
    # -keep class com.yourcompany.realm.**  *; 

-keep class io.realm.annotations.RealmModule
-keep @io.realm.annotations.RealmModule class *
-keep class io.realm.internal.Keep
-keep @io.realm.internal.Keep class *
-dontwarn javax.**
-dontwarn io.realm.*
-keep class cz.msebera.android.httpclient.**  *; 
-keep class com.loopj.android.http.**  *; 

*

【讨论】：

如果它有帮助，请给予权利，我将获得 15 个学分

【参考方案2】：

如果您在项目中使用领域，请尝试将其添加到 proguard 文件中。

-keep class io.realm.annotations.RealmModule
-keep @io.realm.annotations.RealmModule class *
-keep class io.realm.internal.Keep
-keep @io.realm.internal.Keep class *
-keep class sun.misc.*
-keep public class android.net.http.SslError
-keep public class android.webkit.WebViewClient
-keep class cz.msebera.android.httpclient.**  *; 
-keep class com.loopj.android.http.**  *; 

-dontwarn javax.**
-dontwarn io.realm.**
-dontwarn android.webkit.WebView
-dontwarn android.net.http.SslError
-dontwarn android.webkit.WebViewClient
