May I call Bundle#putString method in API level 19?

Question

In documentation for API level 19, there is no putString method in Bundle class. But I can call Bundle#putString method and my app works fine.

May I call putString method ?
Why do my app work fine ?

Environment:

• Write code by Kotlin
• Android Studio 2.1.1
• compileSdkVersion 24
• buildToolsVersion 24.0.1
• nminSdkVersion 17
• targetSdkVersion 24

Answer 1

It works because the Bundle extends BaseBundle which has putString(). So, yes you can use it. :)

Answer 2

I suppose that you can use putString. Another option is to use putCharSequence (String is a CharSequence)
