Crash on Unity for Android #114

Open shikui08 opened 6 years ago

shikui08 commented 6 years ago

Simply imported Utf8Json.Unity.1.3.7.1.unitypackage.

My usage is very simple:

Debug.Log("Before JsonSerializer");
byte[] b = JsonSerializer.Serialize(data);
Debug.Log("After JsonSerializer");

Where data is instance of some very basic classes, such as.

class A
{
   public String a = "";
}  
class B : A 
{
  public String b = "";
}

Everything works well on Windows, both in editor and standalone . However, when compiled & run on Android, Unity crashes without any useful information. Had to Debug.Log a lot like above. Took my a lot of time until I found out that JsonSerializer.Serialize(data);is suspicious because the Log prints:

Unity version is 2017.1.0f3. Please anybody can help me? Is this just some bizarre behavior I encountered or a common bug? Can somebody test on Unity/Android?

Thanks guys!

Updates: Along with Utf8Json, I also tested Newtonsoft.Json, fastJson. All work great in Unity Editor and none works on Android with almost identical crash log.

Only exception is UnityEngine.JsonUtility and it works on all occasions, .

My Unity project settings:

Scripting Runtime Version (.Net 3.5 equivalent)
Scripting Backend (Mono)
API Compatibility level (.Net 2.0 subset)
