(Android) Problems passing props from native code to javascript

[niedem]

I tried passing a prop from android native code to react-native, on the startup. However, even after copying the exact code from the docs it failed to work.

React Native version: 0.60.3

Steps To Reproduce

1. Created a completely blank project
2. Added the code from the docs
3. Started the app

Describe what you expected to happen:
A text should appear in the app, however all i got was a blank space.

Snack, code example, or link to a repository:
In my MainActivity.java, under my ReactActivityDelegate:

@Override protected Bundle getLaunchOptions() { Bundle initialProperties = new Bundle(); initialProperties.putString("testString", "This should be displayed now"); return initialProperties; }

In the render method of my app.js:

<Text>{this.props.testString}</Text>
