I'm new using React Native Navigation and I'm having a problem during the installation process for Android.

So i installed the package, and followed instructions until step 5. Once there i add the code to MainApplication.java, but after doing that, i execute react-native run-android and i get the following error.

enter image description here

I read in other posts that the problem could be solved by executing npm start -- --reset-cache but that doesn't work for me.

Im using react native navigation v1.1.298

Any help will be appreciated.

Thank you.

I am facing the same problem. Looks like this library doesnt work properly with react-native version > 0.49. Because in previous react native versions it had index.android.js, index.ios.js and index.js but now it only generates a single index.js file.

You need to copy index.js file and duplicate 2 new files naming them index.android.js and index.ios.js

Note: If you are following any tutorial and have not added any routing code yet then you will get a blank screen after this step. Dont worry its just the Splash. Once you write navigation code it will work fine.

For anyone encountering this issue on Windows while running Watchman file watch service, it is likely due to this issue https://github.com/facebook/react-native/issues/14246

Upgrading jest to version => 21.0.0 fixes the root cause.
This can be accomplished via npm i react-native@0.50.0 which will cover RN's dependents up to that version as well as npm i jest@21.2.0

Hope this helps someone

It's an old question.

But the problem is probably because your java entry file doesn't have getJSMainModuleName function. You can check this function if you create a new RN project.
