Expo React Native 应用程序在 Android 上崩溃，但在 Expo 上运行 Go

Question

When I'm previewing my app in the Expo Go application everything works just fine, but when I build the android APK everything works great until I try to load the screen which contains the MapView. When I go to that page the app crashes without telling me what's wrong

This is the MapView:

<MapView
    ref={map}
    style={styles.map}
    provider={PROVIDER_GOOGLE}
    initialRegion={location}
    pitchEnabled={false}
    userLocationUpdateInterval={3000}
    userLocationPriority="balanced"
    toolbarEnabled={false}
    tintColor="#00B4B4"
    customMapStyle={customMapStyle}
/>

btw, I have no Idea how to see the crash log if there is any log(I'd love to know how to see it)

You need to add Google Maps Api key. In expo go, expo has their own Google Maps Api key, but when you build your own apk you need to add your own.Check this from expo docs: https://docs.expo.dev/versions/latest/sdk/map-view/#deploying-google-maps-to-an-android-standalone
