This is my function component using react native community camera roll. It's mostly copied from the examples in the readme from github: https://github.com/react-native-cameraroll/react-native-cameraroll
I do use the expo app on my android 11 phone to test and debug the rn app.
import * as React from 'react';
import {PermissionsAndroid, Platform, ScrollView, Image} from 'react-native';
import {Text, View} from "./Themed";
import CameraRoll, {PhotoIdentifier} from '@react-native-community/cameraroll';
import {useState} from 'react';
type CameraRollButtonProps = {}
export default function CameraRollButton({}: CameraRollButtonProps) {
const [photos, setPhotos] = useState<PhotoIdentifier[]>([]);
async function hasAndroidPermission() {
const permission = PermissionsAndroid.PERMISSIONS.READ_EXTERNAL_STORAGE;
const hasPermission = await PermissionsAndroid.check(permission);
if (hasPermission) {
return true;
}
const status = await PermissionsAndroid.request(permission);
return status === 'granted';
}
const onPress = async () => {
if (Platform.OS === "android" && !(await hasAndroidPermission())) {
return;
}
CameraRoll.getPhotos({
first: 20,
assetType: 'Photos',
})
.then(r => {
setPhotos(r.edges);
})
.catch((err) => {
console.log("error catched: " + err);
})
};
return (
<View>
<Text onPress={onPress}>
Camera Roll
</Text>
<ScrollView>
{photos.map((p, i) =>
<Image
key={i}
style={{
width: 300,
height: 100,
}}
source={{uri: p.node.image.uri}}
/>
)}
</ScrollView>
</View>
);
}
When I pressed the button first, I got the permission prompt on which i clicked allow. Then I got this error:
[Unhandled promise rejection: TypeError: Cannot read properties of undefined (reading 'getPhotos')] at node_modules/@react-native-community/cameraroll/js/CameraRoll.js:205:32 in saveToCameraRoll at components/CameraRollButton.tsx:34:19 in onPress
I installed the module via sudo npm i @react-native-community/cameraroll --save
. I also tried to execute this line from the readme later: react-native link @react-native-community/cameraroll && npx pod-install
. It didn't seem to do anything and as I understood I don't need it as there is auto linking.
I also deleted node_modules and reinstalled everything. Still the same error. I also tried installing the module via expo install
.
I'm still not sure what the problem was, but I guess using expo might be a problem. I forgot that expo comes with a lot of modules so I ended up using https://docs.expo.dev/versions/v42.0.0/sdk/media-library/ without any problems.
