I have the following folder structure in Android Studio:
├── androidTest │ ├── java │ └── res │ └── raw │ └── test_file └── main ├── java └── res └── raw └── app_file I'm trying to access the test_file resource which exists in the raw folder of the androidTest elements. Here's the code inside a Robotium test case that inherits from ActivityInstrumentationTestCase2:
InputStream is = this.getInstrumentation() .getContext() .getResources() .openRawResource(R.raw.test_file); Android Studio throws a reference error since the resource cannot be found. The exact error is "Cannot resolve symbol test_file".
How can I reference this resource form a test case, which exists on the androidTest resources bundle?

The raw folder is created inside the res folder: main/res/raw. So we will simply create it inside the res folder. But before creating a raw folder let’s have a look at the asset folder in android which acts the same role as the raw folder in android studio. So let discuss how the resource raw folder is different from the assets folder?
However, if all you require is the ability to read raw data (such as a video or audio file), then save the file in the res/raw/ directory and read a stream of bytes using openRawResource (). Android contains a number of standard resources, such as styles, themes, and layouts.
assets: No simple way the developer can arrange an XML file (e.g. AndroidManifest.xml) to point to the file in the assets folder. res/raw: In any XML files like in Java, the developer can access the file in res/raw using @raw/filename easily. So if you need to access your file in any XML, put it in the res/raw folder.
if you have androidTest resources in the right directory, then you can only access them via com.example.my.app.debug.test.R !!!! Even without applicationIdSuffix you should use < applicationId>.test.R in case applicationId is different than your package name. See Android Unit Tests Requiring Context.
By default your androidTest project will include your app's R class, but androidTest's resources will be generated into a separate file. Make sure you import the R class from your test project:
import com.your.package.test.R; [..] getInstrumentation().getContext().getResources().openRawResource(R.raw.test_file); You can also directly reference the test project's R class:
getInstrumentation().getContext().getResources().openRawResource(com.your.package.test.R.raw.test_file); I had the androidTest resources in the right spot (src/androidTest/res) and I still couldn't access them via <normal.package>.test.R. I spent a lot of time googling trying to figure out what was going on..
I FINALLY stumbled onto the answer. If you're building a buildType where you specified an applicationIdSuffix, your files are at <applicationId><applicationIdSuffix>.test.R !!!!
i.e.
applicationId "com.example.my.app" buildTypes { debug { applicationIdSuffix ".debug" } } if you have androidTest resources in the right directory, then you can only access them via com.example.my.app.debug.test.R !!!!
