QRCode.from cannot be resolved in Android Studio

[surajs02]

Android Studio cannot resolve QRCode.from when trying to convert String to QRCode in this code:

// ...
@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ByteArrayOutputStream stream = QRCode.from("Hello World").stream();
    }

Using QRGen android 2.5.0 from jitpack.io.

project build.gradle:

allprojects {
    repositories {
        // ...
        maven { url 'https://jitpack.io' }
    }
}

app build.gradle:

dependencies {
    // ...
    implementation 'com.github.kenglxn.QRGen:android:2.5.0'
}
