I have solve the crash problem

  private final Gson gson = new GsonBuilder().addSerializationExclusionStrategy(
    new ExclusionStrategy() {
    @Override
    public boolean shouldSkipField(FieldAttributes f) {
        return false;
    }

    @Override
    public boolean shouldSkipClass(Class<?> clazz) {
        if(clazz.getSimpleName().equals("SimpleDateFormat"))
            return true;
        return false;
    }
}).create();

use above code to construct gson object
