I'm trying to make a class for instrumentation test. This class is in the androidTest folder app\src\androidTest\java\.... However, AndroidJUnit4 and ActivityTestRule cannot resolve. In the import statement, import android.support.test.runner.AndroidJUnit4 the word "runner" is in red. The test class is in Kotlin. I tried deleted it and created one in Java, but still cannot import AdnroidJUnit4. I read some similar questions but didn't find the solution to my case. Those two are the project and app build.gradle files:
Is there anything wrong with my gradle files?
app build.gradle:
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'

update Finally find out that this is because a blank space in project path. I removed the space and now can import the classes.
