If everything is correct, then you'll need something like this to read it:

public String readFileFromAssets(String fileName, Context context) throws IOException {
    InputStreamReader stream = new InputStreamReader(context.getAssets().open(fileName));
    Preconditions.checkNotNull(stream, "Stream is null");
    BufferedReader reader = new BufferedReader(new InputStreamReader(stream, "UTF-8"));
    return IOUtils.toString(reader);
}

You need to pass Context for it to work.

Another thing to verify if you have configured assets in Gradle correctly? Here is just an example:

sourceSets {
    main {
        java.srcDirs = ['src/main']
        // can be configured in different way
        assets.srcDirs = ['src/androidTest/assets']
        // other things, examples
        res.srcDirs = ['res']
        manifest.srcFile 'AndroidManifest.xml'
    }
}
