问题 I want to animate the backgroundColor of a ScrollView, but always get a warning - and a non-animating ScrollView. Am I hitting a bug? Or is it simply not supported on a ScrollView?

Relevant code snippets: <Animated.ScrollView contentContainerStyle={[ styles.container, this.getCurrentColorOfBackground() ]}> <Text onPress={this.onPress} style={styles.question}> {this.state.question} </Text> </Animated.ScrollView> the

问题 I am making a React native app, with native services to scan for devices nearby. It works fine when the app is in foreground, but when the app is killed and the service detects a device, it wakes up the React Native part of app by headless JS and makes an API call using redux action, but it cannot store the data received from API call in reducer data.

问题 I am using Expo Image Picker to send a cropped image to s3. The file is being uploaded, but it does not render as an image as its not recognised as one. If I took the blob data and use it in a base64 to image encoder I get the image, so it must be mime or encoding based, here is what I have. I invoke the Expo Image Picker with; let pickerResult = await ImagePicker.launchImageLibraryAsync({ allowsEditing: true, aspect: [1, 1], base64: true, exif: false, }); The params I use to create the
