Android不支持fastjson2么？

问题描述

Android ART虚拟机不支持fastjson2, 缺少类 java.lang.NoClassDefFoundError: Failed resolution of: Ljava/lang/management/ManagementFactory

环境信息

OS信息： Android10 API 29 JDK信息： Android ART 版本信息：Fastjson2 2.0.3

重现步骤

1. 使用 JSON::toJSONString(Any) 方法
2. 输入数据

var obj = object { var message = "Hello" }

1. 出现 java.lang.NoClassDefFoundError: Failed resolution of: Ljava/lang/management/ManagementFactory 错误

val obj = object { var message = "Hello" } val jsonString = JSON.toJSONString(obj) println(jsonString)

期待的正确结果 在JDK 11上实际输出如下 {"message":"Hello"}

安卓期望输出 {"message":"Hello"} 实际报错

相关日志输出

E/AndroidRuntime: FATAL EXCEPTION: main Process: com.example.myapplication, PID: 31029 java.lang.NoClassDefFoundError: Failed resolution of: Ljava/lang/management/ManagementFactory; at ...

E/AndroidRuntime: Caused by: java.lang.ClassNotFoundException: Didn't find class "java.lang.management.ManagementFactory" on path: DexPathList[[zip file "/data/app/com.example.myapplication-DSxjsAQ_wm5Pn6Uxsz3adQ==/base.apk"],nativeLibraryDirectories=[/data/app/com.example.myapplication-DSxjsAQ_wm5Pn6Uxsz3adQ==/lib/arm64, /data/app/com.example.myapplication-DSxjsAQ_wm5Pn6Uxsz3adQ==/base.apk!/lib/arm64-v8a, /system/lib64, /hw_product/lib64, /system/product/lib64]]

附加信息

原因是安卓ART虚拟机缺少类java/lang/management/ManagementFactory
