Intent and Bundle Relation

Question

While using Intent object we can put different types of data directly using its putExtra(). We can also put these extra data into a Bundle object and add it to Intent. So why do we need Bundle if we can do so using Intent directly?

Answer 1

As you can see, the Intent internally stores it in a Bundle.

public Intent putExtra(String name, String value) {
    if (mExtras == null) {
        mExtras = new Bundle();
    }
    mExtras.putString(name, value);
    return this;
}

Answer 2

Sometimes you need to pass only a few variables or values to some Other Activity, but what if you have a bunch of variable's or values that you need to pass to various Activities. In that case you can use Bundle and pass the Bundle to the required Activity with ease. Instead of passing single variable's every time.
