An error occurred while installing failed to fetch URL in Android SDK http://dl-ssl.google.com/android/repository/addons_list-1.xml

Recently, an android-sdk-windows.rar was downloaded from google, and the SDK manager was clicked. The API level cannot be refreshed, and a lot of information was found online. To solve this problem, the modification of hosts, HTTP, and HTTPS cannot be solved, this has brought me a lot of confusion! An error occurred while loading the interface:

I am so confused that the connection has failed. Does China Telecom block Google Android? recently, I have an idea: How does China Telecom shield android but not Google search engines, if China Telecom shields Google search engines, it is estimated that China Telecom will also collapse! I made a choice and used www.google.com as the proxy. For details, see:

 

Then I Click Reload under a package to reload the package. The API level is all displayed. It's really cool. I hope to help you ~

I have read my comments. I have a lot of comments and I am very happy to meet many of my friends. However, I have been tossing Android for several years. Let's talk about some of my experiences:
If you want to learn Android well, you must go out of your own way. Otherwise, you can think independently and draw a picture if you cannot do it. Any problem that never happens is that you have no idea or logic, I once failed to solve many problems, and finally forced myself to solve the problems. This is persistence and responsibility! Today, I have developed a habit and an unyielding mind. You must know that if someone else can implement the function, you can certainly, because you are no worse than others, it only takes less time than others! Having confidence in yourself, learning the program right after a stage, not writing code, is a kind of thinking, It is a brand new realm, if we get to the end early, we will be able to see the world more thoroughly! People are at different levels, and their realm is also different. The calm attitude is like water, and the unyielding attitude will be doomed to a person's extraordinary! In a word, you have to rely on yourself. I hope you will have to think more and try harder in the future! It is a good thing to discover and solve problems!

By the way, I am not too young. In order to do my own things, I have some entrepreneurial ideas. If a startup friend lacks a loyal partner, please contact me! (Focus on Android iOS development. I don't have the same IQ as my God, but I have an unyielding mind. I don't bow down for difficulties, but I work hard for my ideals)
