四大组件中的三大组件（Activity、Service、Receiver）都是支持在Intent中传递Bundle数据的，由于Bundle实现了Parcelable接口，所以它可以方便地在不同的进程之间传输。当然，传输的数据必须能够被序列化，比如基本类型、实现了Parcelable接口的对象、实现了Serializable接口的对象以及一些Android支持的特殊对象，具体内容可以看Bundle这个类，就可以看到所有它支持的类型。Bundle不支持的类型无法通过它在进程间传递数据。
Intent intent1 = new Intent(MainActivity.this, ThirdActivity.class); Bundle bundle = new Bundle(); bundle.putCharSequence("name", "zhangmiao"); bundle.putInt("age", 20); intent1.putExtras(bundle); startActivity(intent1);
Intent intent = getIntent(); Bundle bundle = intent.getExtras(); String name = bundle.getString("name"); int age = bundle.getInt("age");
<activity ... android:process=":remote" />
