android – 如何将非parcelable对象从活动传递到另一个活动？

我有两个对象从两个不同的类实例化,这两个类不实现parcelable或serializable.我希望tp将这些对象传递给
另一个活动,所以我写了下面的代码：

*码：

//send object
 Intent intConnect = new Intent(mCtx.getApplicationContext(),ActConnect.class);
            Bundle bndConnect = new Bundle();
            bndConnect.putParcelable("HeaderModel",(ParcelablE) mHeaderModel);
            bndConnect.putParcelable("DetailsModel",(ParcelablE) mDetailsModel);
            intConnect.putExtras(bndConnect);
            intConnect.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            mCtx.startActivity(intConnect);

//receive objects in the receiving activity
 Bundle extras = geTintent().getExtras();
    Header headerModel = (Header) extras.get("HeaderModel");
    Details detailsModel = (Details) extras.get("DetailsModel");

但在运行时,我收到以下logcat：

logcat的：

如何将非可分配对象从活动传递到另一个活动？

public class ModelClass implements serializable{

  // Other stuff

}

Intent mIntent = new Intent(mContext,NextActivity.class);
mIntent.putExtra("HeaderModel",mHeaderModel);
startActivity(mIntent);

Header headerModel = (Header) geTintent.getserializableExtra("HeaderModel");
