After setting up font theme with native base using this guide https://docs.nativebase.io/Customize.html#theme-font-headref my app crashes after opening it in android without throwing any error.
It works fine in IOS.
Any similar experience?

I am seeing no error in visual studio react native and android bundle is also working fine. But when android simlator tries to open the expo go then my app suddenly stopes by closing the app.
Please help me regarding this. I stuck in this.
Basically the title says all - Can native react app code convert/rollback to native mobile code(ios and android)?
Background - there is a react native app and there are some bugs and I would like to export the react native code to their native app code (ios and android) which I can fix them in native apps.
No. The React Native JavaScript is never translated into Swift or Java code and then compiled - it runs within the Safari or Chrome JavaScript engines. See here for more details.
However, as its name implies, React Native does rely on native code for more complex operations. If the bugs are in those npm modules you might be able to fix them there.
I recently updated expo clients (both android and ios) of my phone and only the android version crashed after trying to play lottie animation (using dangerzone). Animations work fine in ios and also it did work in android before i update the apk.
I dont get any error message when the app crash, i only get system message saying "app crashed". Anyone know how to fix this?
When I start a new React Native project on a Mac with the latest versions XCode and React Native as follows:
react-native init TestApp
cd TestApp
react-native run-iso
react-native --version
react-native-cli: 1.0.0
react-native: 0.32.0
the app launches correctly in the iOS simulator in portrait and looks as expected.
However, when rotating the orientation by selecting from the menu Hardware --> Rotate Left the text is no longer centered and is cut off.
I have tried a few other tests with flexbox and see similar behavior when rotating on iOS. I also tried resetting the iOS emulator contents and settings using Simulator --> Reset Contents and Settings but I still see the same issue.
I launched a new app using the same procedure on Mac for iOS on another machine running the previous version of React Native (0.31) and it works as expected and responds normally when the orientation is changed.
In both, 0.32 and 0.31 everything displays correctly on an Android app running in the simulator.
I am unclear if this is a misconfiguration on my desktop or if there is an issue in React Native 0.32.
I downloaded some react-native code from "https://github.com/lelandrichardson/react-native-maps" and launch the examples on ios simulator. I got below error showing on IOS simulator. As it suggested how to make javascript and native code in sync?
