problem is that I used  RecycleView  in the project, and then I introduced him, but gradle reported an error, which specifically means: 
- 
The version numbers of the libraries supported by RecycleVieware not consistent with those of other libraries. Other version numbers have been found, and you should use a consistent version number to avoid compilation errors.
-  the current RecycleViewversion number (28.x.x) is higher than the compiled version number (26).
 I tried to fix the No. 2 problem above by changing the version number of  RecycleView  to the same version as the current compiled version, but the first problem still exists. I tried to open the  Android Studio  left sidebar,  External Libraries  to see different version numbers, as shown below: 
 
build.gradle
supportbuild.gradle26.1.0 :
Android Studio 3.0.1Deepin linux Windows 10Android Studio 3.3 External Libraries2
 
 
 I would like to ask bosses, how to solve this problem, ah, I am multi-Module mode, the use of  api  mode introduction, will it be a problem in this respect? Solve! ~
