Problem at the picture, the latest official version AS a new installation, abnormal red arrow in figure after the new project, just looking at abnormal, no error message,
The arrow icon in the upper right corner of just have red, green, the direction key, what do you mean? How to eliminate?
Three or four arrow icon grey circle slash what mean? How to make it into a green tick?

CodePudding user response:

This has no specific studied, speculation is to be able to run and debug, as for the forward slash is probably your little compileSdkVersion version

CodePudding user response:

Red, green, the direction key should only be used to indicate this is a test file, is used to write test code, as for the gray ICONS, each item is gradle task, used to compile the project, gray optimization should be gradle do, may be detected you didn't write test code, and then automatically skip don't compile.

CodePudding user response:

Unit test, and don't like to delete directly
