Understanding of Android's JDK, SDK, eclipse

Today, reading this, I learned something:

First, the JDK is used to handle the Java language,

The SDK is used to handle the association between the Java language and the hardware.

Eclipse is used to write the Java language,

Through this understanding, deepened my understanding of the development of Android,

And there's a thing called Adtbundle, which integrates the SDK and eclipse to make it easier for users to configure their environment.

Forgetting to say, there is a point where you can import directly between Eclipse and the JDK, which eclipse can do.

However, Eclipse cannot directly accept the SDK, and before the SDK can be accessed by installing ADT, ADT is a bridge between the middle, but now it's all in the Adtbundle, so there's no need for cumbersome configuration, Only need to install the Adtbundle, then configure the user installed JDK can be used, this really saves the user a lot of trouble.

Here's a picture to illustrate this:
