Question

我在Android应用程序中使用signalR核心Java客户端。在启用minify之前，它工作正常，但是在启用它之后，signalR连接到服务器，但仅在第一次调用时出现了此错误：

java.util.concurrent.CancellationException: Invocation was canceled.

我现在不是这个错误是针对signalR或okhttp的，所以我添加了但在proguard中。这是我的监护人中的这2个。


##------------------- signalR -----------
-keep class microsoft.** { *; }
-dontwarn org.slf4j.**
##--------------- okhttp  —------—
-keepattributes Signature
-keepattributes *Annotation*
-keep class okhttp3.** { *; }
-keep interface okhttp3.** { *; }
-dontwarn okhttp3.**
-dontnote okhttp3.**

##--------------- Okio  —------—
-keep class sun.misc.Unsafe { *; }
-dontwarn java.nio.file.*
-dontwarn org.codehaus.mojo.animal_sniffer.IgnoreJRERequirement

Answer 1

这是我的错，因为我以前使用signalR（不是核心），并且为此添加了proguard

-keep class microsoft.** { *; }

我必须为signalR内核更改它并添加

-keep class com.microsoft.** { *; }

SignalR调用已取消
