invocationtargetexception по време на gson.fromJson()

Пиша библиотека, която прави много неща.

Ситуация: в моя Android проект AAA включвам библиотеката XXX и произлизам от абстрактен клас A (който се намира в библиотеката XXX).

Когато се опитвам да извикам производния клас в библиотеката XXX, GSON не намира класа (в програмата за отстраняване на грешки виждам правилния клас - той беше предоставен на фабриката преди)

Gson спира с InvocationTargetException по време на процеса на разрешаване. Точно същият клас работи, ако е част от библиотеката XXX

JSON:

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

код:

  // 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;

}

Как мога да разреша това?

което има смисъл, тъй като XXX няма как да знае за ? extends A1   -  person njzk2    schedule 19.02.2013

Класът се дава чрез параметър.   -  person elCapitano    schedule 19.02.2013

не записваш ли изключението? можете ли да публикувате проследяването на стека?   -  person njzk2    schedule 19.02.2013

Опитайте да извикате clazz.newInstance() и вижте дали наистина можете да създадете класа.   -  person mercutio    schedule 19.02.2013

'clazz.newInstance()' работи много добре   -  person elCapitano    schedule 19.02.2013

Това изглежда като безкрайна рекурсия... Бихте ли публикували кратък откъс от json, който причинява това?   -  person mercutio    schedule 19.02.2013

Добре, ще опитам... за съжаление работи перфектно, ако класът за създаване е част от библиотеката... :(   -  person elCapitano    schedule 19.02.2013

понижаването на GSON lib беше решението за това. Благодаря! Меркуцио, моля, запиши го като отговор, тогава ще получиш точките   -  person elCapitano    schedule 19.02.2013
