gson.fromJson（）期间的invocationtargetexception

标签： android reflection gson

我正在写一个做很多东西的库。

情况： 在我的android项目AAA中，我包含了库XXX，并从抽象类A（位于库XXX中）派生。

当我尝试在库XXX中调用派生类时，GSON找不到类（在调试器中我可以看到正确的类 - 它之前已提供给工厂）

Gson在解决过程中以InvocationTargetException停止。如果它是库XXX

的一部分，则完全相同的类可以工作

JSON：

    {
      "subtext":"super subtext!!!",
      "myText":"hello 1",
      "id":"ff8081813cf34f79013cf34fba750001",
      "myAAA":false, 
      "version":0
    }

代码：

  // code to invoke (in library XXX)
  public static A fromJson(String gsonString,
        Class clazz) {
    A myAbstractClass = null; // A1 is a subclass of A
    try {
        Gson gson = new Gson();
        myAbstractClass = gson.fromJson(gsonString, clazz);
    } catch (Exception e) {

    }
    return myAbstractClass;

}

我该如何解决这个问题？

编辑：stacktrace
