我应该使用什么 package 来替换最新 AndroidStudio 中的“android.support.test.rule.ActivityTestRule”？

Question

I've been debugging a program in AndroidStudio. The program needs the class "ActivityTestRule" but it shows:

“Cannot resolve symbol 'ActivityTestRule' ”

-the code where ActivityTestRule is used-

I'm using the newest version of AndroidStudio with the newest version of gradle. It suggests that there's no android support-v7. So I use "androidx.test" to replace most packages under "android.support.test", but I cannot find the package to replace "android.support.test.rule.ActivityTestRule".

What should i do? (Better just change the "import" part of code)

Answer 1

OK, I've solved this myself:

Project structure -> Add the dependency "com.android.support.test:rules:1.0.2" to app denpendencies ->Apply->Done.

In code:

#import androidx.test.rule.ActivityTestRule;
