[Solved] Could not resolve com.android.support:appcompat-v7:28.0.0

20181008 is always wrong could not resolve com.android.com support:appcompat-v7 :28.0.0

1. First, I suspected that I had downgraded jdk 1.8 some days ago, so I reinstalled jdk 10
	java --version
		java 10.0.2 2018-07-17
		Java(TM) SE Runtime Environment 18.3 (build 10.0.2+13)
		Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.2+13, mixed mode)
2, exit AS, re-build a new project, still these errors

3, then suspect the SDK, confirm from api19 to api28 are correctly installed, start over, still errors
4, Reference.

5、Remove offline
	*** I am going to work online anyway
	Menu: File -- Other Settings -- Default setting--Build, Excution, Deployment--Gradle
	Find the Offline work on the right and uncheck it!


6、Or open Preference
*** My Mac is used to setting it from here


*** The 2 places above are not exactly the same!

7, open build.gradle and sync now again, and this time it's all over!
