How to build an example app as release build?

[Yaski]

I have an issue with the library on some devices.
To test with example app I want to build it as realease apk.
I tried to do bundle js code using command:

react-native bundle --entry-file index.js --platform android --dev true --bundle-output dist/main.android.jsbundle --assets-dest dist/res

And then to make apk I used yarn android:build command. But it doesn't copy assets properly and I cannot start the app, it gives an error that assets are not available.
Are there any other way to make an apk?
