This is a regression in AS 3.6 RC 1 and RC 2.
I previously reported it as https://issuetracker.google.com/issues/123557197 for an older version of AS.
I was asked to file a new issue, so here it is.

Since upgrading to Android Studio 3.6 RC 1 or RC 2, the IDE no longer recognises string resources declared with resValue in a custom build task. They show up red in the IDE.

The code still compiles and runs correctly, so it's just an IDE bug where it is unable to resolve these symbols.

This worked fine with AS 3.5 so it's a regression in 3.6.

STEPS TO REPRODUCE


1. Define a custom task in your app's build.gradle which declares some resources.

    task generateSomeAppResources {
        doFirst {
            android.defaultConfig.resValue "string", "generated_app_resource", "Some generated value for the app"
        }
    }

    preBuild.dependsOn(generateSomeAppResources)


2. Reference this resource in your app code.

    @Override
    public void onCreate() {
        super.onCreate();
        setContentView(R.layout.activity_main)

        Toast.makeText(this, R.string.generated_app_resource, Toast.LENGTH_SHORT).show()
    }

3. Verify that the app compiles and runs successfully, and the toast is shown correctly.

4. Search for the name of the resource, and observe that it exists in generated resource files.

$  ag generated_app_resource .
app/build.gradle
30:        android.defaultConfig.resValue "string", "generated_app_resource", "Some generated value for the app"

app/build/generated/res/resValues/debug/values/gradleResValues.xml
7:    <string name="generated_app_resource" translatable="false">Some generated value for the app</string>


5. Notice that the IDE is flagging this resource in red. Attempting to "Go to declaration" results in an error: "Cannot find declaration to go to".

See attached screenshot and sample project to reproduce the issue.
