Conclusion

Now, the android development environment has been set up. If you have any questions, please leave a message. Note that I only downloaded the android SDK R4 upgrade tool. Instead of downloading the specific SDK, I upgraded it through the android SDK management tool in eclipse, you can also download the specific SDK version directly, for example, Android SDK 2.1 R1 has this download link, but it is better to use the upgrade tool for my task.
