After I upgrade my project to AndroidStudio 3.0-beta1, my androidTest files stopped compiling.

A lot of packages are not found, some of them are:

error: package android.support.annotation does not exist
error: cannot find symbol class StringRes
error: cannot access AppCompatActivity
class file for android.support.v7.app.AppCompatActivity not found

I already added

androidTestCompile "com.android.support:support-annotations:25.3.1"

into build.gradle

But even with this, I have the errors of package not found. I tried running the tests from inside Android Studio and from terminal with ./gradlew connectedCheck

Just add this to your dependencies

implementation 'com.github.bumptech.glide:glide:4.9.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.9.0'
implementation "com.android.support:support-annotations:28.0.0"
annotationProcessor 'com.android.support:support-annotations:28.0.0'

In my case it happened after migrating to androidX . The decision merely was :

go to the *.java file(s) pointed and comment strings with packages

 //import android.???

and re-import androidX-ed ones.

Build the project again and you are done.

Try this:

import androidx.annotation.StringRes

I had got similar errors and corrected it by adding.

LOCAL_STATIC_JAVA_LIBRARIES += android-support-v4
inside your Android.mk folder.

Note: This is for change in binary directly where you have to run .mk file separately. If using Android Studio, check Writing Android.mk file in Studio.
I read the previous answer and wanted to provide a different approach to correct it although its harder this way.
