基本上我将对象保存为Bundle中的Serializable，然后通过putExtras()将Bundle保存在Intent中。如果我在同一个Activity上从Bundle获得Serializable，我能够成功完成：
Bundle bundle = new Bundle();
bundle.putSerializable("value", myObj);
i.putExtras(bundle);
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
MyObj temp = (MyObj) bundle.getSerializable("value");
}
}, 3000);
但是，当我调用startActivity()移动到第二个Activity时，应用程序崩溃了：

为什么会这样？我想在第二个Activity中检索该对象。我可以访问此第三方库（AdViewController类）的源代码，并将其设为implements Serializable。检查instanceof Serializable表示myObj已被序列化。
答案 0 :(得分：1)
问题的主要原因是：
Caused by: java.io.NotSerializableException: com.mopub.mobileads.AdViewController
表示您的类不可序列化。确保AdViewController还实现了可序列化的接口
答案 1 :(得分：0)
确保MyObj在您想要使用之前已实现Serializable接口 bundle.putSerializable（＆＃34; value＆＃34;，myObj）。
