I am working on a react native video call app, I use react-native-agora, everything works fine except the
remote video quality is extremely bad, I can see nothing, it is only freezing.
I use react native agora version : 3.2.2
My rtcEngine init function :
/**
* #name init
* #description Function to initialize the Rtc Engine, attach event listeners and actions
*/
const init = async () => {
const {token, appId} = await getToken();
setAppId(appId);
setToken(token);
engine = await RtcEngine.create(appId);
await engine.enableVideo();
await engine.enableAudio();
await engine?.joinChannel(token, `${session.id}`, null, 0);
engine.addListener('Warning', (warn) => {
console.log('Warning', warn);
});
engine.addListener('Error', async (err) => {
if(err === 17){
if(!engine){
engine = await RtcEngine.create(appId);
}
await engine?.leaveChannel();
setPeerIds(peerIds => []);
await engine?.joinChannel(token, `${session.id}`, null, 0);
}
console.log('Error', err);
});
engine.addListener('UserJoined', async (uid, elapsed) => {
console.log('UserJoined', uid, elapsed);
// Get current peer IDs
// If new user
if (peerIds.indexOf(uid) === -1) {
setPeerIds(peerIds => [...peerIds, uid]);
}
});
engine.addListener('UserOffline', (uid, reason) => {
console.log('UserOffline', uid, reason);
setPeerIds(peerIds => [...peerIds.filter((id) => id !== uid)]);
});
// If Local user joins RTC channel
engine.addListener('JoinChannelSuccess', (channel, uid, elapsed) => {
console.log('JoinChannelSuccess', channel, uid, elapsed);
// Set state variable to true
setJoinSucceed(true);
});
}
Thanks in advance.
I finally solved my problem, for those who have the same issue, I let here my solution:
I just make this videoEncoderConfiguration :
await engine.setVideoEncoderConfiguration(new VideoEncoderConfiguration({
dimensions: new VideoDimensions(320, 240),
bitrate: 140,
frameRate: VideoFrameRate.Fps30,
degradationPrefer: 0
}))

Trying to implement apple sign in in my expo managed project and the sign in doesnt work in production. I have followed all the documentations steps. Changed the bundle ID to the right one.
const handleAppleRegister = (dispatch) => async () => {
try {
// await firebase.auth().signOut() // sign out first
const nonce = Math.random().toString(36).substring(2, 10);
return await Crypto.digestStringAsync(Crypto.CryptoDigestAlgorithm.SHA256, nonce)
.then((hashedNonce) =>
AppleAuthentication.signInAsync({
requestedScopes: [AppleAuthentication.AppleAuthenticationScope.FULL_NAME, AppleAuthentication.AppleAuthenticationScope.EMAIL],
nonce: hashedNonce
})
)
.then((appleCredential) => {
const { identityToken } = appleCredential;
const provider = new firebase.auth.OAuthProvider('apple.com');
provider.addScope('email');
provider.addScope('name');
provider.addScope('displayName');
provider.addScope('photoURL');
const credential = provider.credential({
idToken: identityToken,
rawNonce: nonce
});
return Firebase.auth().signInWithCredential(credential).then(async resp => {
console.log(resp)
const currentUserUID = resp.user.uid;
const db = firebase.firestore();
db.collection('users').doc(currentUserUID).set({
email: resp.additionalUserInfo.profile.email,
uid: resp.user.uid,
});
await AsyncStorage.setItem('status', 'apple');
dispatch({ type: 'handleAppleRegister', payload: 'apple' });
});
})
.catch((error) => {
// ...
console.error(error);
});
} catch (e) {
if (e.code === 'ERR_CANCELED') {
// handle that the user canceled the sign-in flow
} else {
// handle other errors
}
}
};
I've searched every where for a solution but with no luck. Anyone knows what is missing here

The useEffect that is being accused of being a problem:
React.useEffect(() => {
// Fetch the token from storage then navigate to our appropriate place
const loadUserData = async () => {
let userData;
try {
userData = await retrieveUserData();
} catch (e) {}
if(userData){
dispatch({ type: 'RESTORE_USER_DATA', userData: userData });
getChatData(userData, setChats, dispatch);
if(userData && !websocketInitialised){
console.log('web init called from *load user data*')
setWebsocketInitialised(true)
initialiseWebsocket(userData);
}
}
else{
dispatch({ type: 'RESTORE_USER_DATA_FAILED'});
}
};
loadUserData();
}, []);
The initialliseWebsocket function
function initialiseWebsocket(userData){
console.log('sending websocket initialisation data.');
websocket.send(JSON.stringify({
'action': 'init',
'data' : {'token': userData.token}
}));
}
the useState that is used above
const [websocketInitialised, setWebsocketInitialised] = React.useState(false);
async function getChatData(userData, setChats, dispatch){
console.log("fetching chat data");
// if we fail to download chat data, pull the old one from FS
const loadOldChatData = async () => {
let chats;
try {
chats = await retrieveChats();
} catch (e) {}
if(chats){
setChats(chats);
console.log("loaded cached chat data") ;
}
else{
setChats([]);
}
};
const onSuccess = (response) => {
if(response['chats']){
storeChats(response['chats']);
setChats(response['chats']);
console.log("chat data synced");
}
else{
loadOldChatData();
}
};
const onFailure = (response) => {
loadOldChatData();
};
fetch(Settings.siteUrl + '/messenger/get_chats/', {
method: "GET",
headers: {
"Content-type": "application/json; charset=UTF-8",
"Authorization": "Token " + userData.token
},
})
.then(response => response.json())
.then(response => {onSuccess(response)})
.catch(response => {onFailure(response)})
}
retrieveUseData() is most likely not the problem as this only started occuring after I added the other code.
Am I not supposed to use states like this or am I supposed to use the async key worked on functions? I tried that but I still have the same issue. You can see on the 4 line of the errors it mentions the 'initialiseWebsocket' function. I am guessing that is the route cause. I assume the solution will be some async version of it...
This error tell us that you didn't or forget to handle error from async code.
I refectory your code a bit, Tell me if you got any error message from console.log(error);
React.useEffect(() => {
// Fetch the token from storage then navigate to our appropriate place
(async () => {
try {
let userData = await retrieveUserData();
dispatch({ type: 'RESTORE_USER_DATA', userData });
await getChatData(userData, setChats, dispatch);
if (websocketInitialised) return;
console.log('web init called from *load user data*')
setWebsocketInitialised(true)
initialiseWebsocket(userData);
} catch (error) {
console.log(error);
dispatch({ type: 'RESTORE_USER_DATA_FAILED' });
}
})();
}, []);
And you should rename getChatData to setChatData, I also simplify those code also...
async function getChatData(userData, setChats, _dispatch) {
try {
let response = await fetch(Settings.siteUrl + '/messenger/get_chats/', {
method: "GET",
headers: {
"Content-type": "application/json; charset=UTF-8",
"Authorization": "Token " + userData.token
},
}),
data = await response.json(),
chats = data['chats'];
if (!chats?.length) throw "empty chat data, pull the old one from FS";
storeChats(chats);
setChats(chats);
} catch (_) {
// if we fail to download chat data, pull the old one from FS
await retrieveChats()
.then(chats => setChats(chats))
.catch(() => setChats([]))
}
}
"I don't really understand what you are doing with the async stuff."
async/await is just syntax sugar of promise, It allow you to work with async operation in a synchronous manner, some rules of async/await
In other to use await keyword, you need an async function.
you can make any function asynchronous, just by adding async keyword
async function always return promise
Lets see an example:
let delay = (ms, msg, bool) => new Promise((res, rej) => setTimeout(!bool ? res : rej , ms,msg));
This helper function create a promise for our example, it take 3 arguments, it take millisecond as 1st arg, to delay, 2rd is the message as payload. 3nd is Boolean; it true, then it will reject.
let delay = (ms, msg, bool) => new Promise((res, rej) => setTimeout(!bool ? res : rej, ms, msg));
let log = console.log;
async function myAsyncFn() {
let hello = await delay(100, "hello,");
let world = await delay(300, " world!");
// we use a symbol '#' to indicate that, its from `myAsyncFn`
log("#" , hello + world, "printed from async operation");
}
myAsyncFn();
log("As you can see that, this message print first");
// we are creating an async function and called immediately, In other to use `await keyword`
(async () => {
try {
let resolved = await delay(300,"resolved");
console.log(">" , `it ${resolved}!`);
// this will reject and catch via `try/catch` block;
let _ = await delay(600, "Error", true);
log("It will not print!");
// ...
} catch (error) {
log(">" , `we can catch "${error}" with try/catch, as like any sync code!`);
}
})()
As you can see that with async/await its look like everything is synchronous right? even everything execute asynchronously!
You just need to use await keyword to make every async operation synchronous.
I want to get user's current location and set it into AsyncStorage a array. I will do it in the useEffect hook. But the problem is my functions are not working that according to given order. Here are my code
useEffect(() => {
getUserLocation();
setUserLocation();
check();
}, []);
/*Get User's Currunt Location*/
const getUserLocation = () => {
GetLocation.getCurrentPosition({
enableHighAccuracy: true,
timeout: 15000,
})
.then((location) => {
var lt = location.latitude;
var lg = location.longitude;
setlatitude(lt);
setlongitude(lg);
console.log("getUserLocation", lt, lg);
})
.catch((error) => {
const { code, message } = error;
console.warn(code, message);
});
};
/*Set User's Currunt Location to AsyncStorage*/
const setUserLocation = async () => {
try {
await AsyncStorage.setItem("user_location", JSON.stringify(userLocation));
console.log("setUserLocation", userLocation);
} catch (error) {
console.log("error setting user location");
}
};
const check = () => {
AsyncStorage.getItem("user_location", (err, result) => {
if (result !== null) {
console.log("check", result);
setlatitude(result.latitude);
setlongitude(result.longitude);
} else {
console.log("Data Not Found");
}
});
};
Whenever you use .then you are scheduling your code to run at some point in the future, when the promise has completed. So setUserLocation runs before the then of getUserLocation.
Also, it looks like your getUserLocation set react state, which won't be available until the next render. We use effects to manage this.
// Get the location on mount
useEffect(getUserLocation, []);
// Whenever the location updates, set it into storage
useEffect(() => setUserLocation().then(check), [latitude, longitude]);
I have a subscriber redis client instance that is performing a callback when entries in the db expire.. I tried adding an initial unsubscribe call to remove previous any existing listeners, but it does not seem to be working:
const setOnExpire = (onExpire) => {
client.config('set', 'notify-keyspace-events', 'Ex', () => {
subscriber.unsubscribe('__keyevent#0__:expired', 0); // <-- this does not seem to be doing what I was hoping it would...
subscriber.subscribe('__keyevent#0__:expired', () => {
subscriber.on('message', function (channel, key) {
onExpire(key);
});
});
});
};
setOnExpire(() => { console.log('foo'); });
setOnExpire(() => { console.log('bar'); }); // my intention is to replace the callback that logs "foo"
client.hmsetAsync(someKey, someAttrs).then(() => {
client.expireAsync(someKey, 5);
});
I run this, hoping to only see "bar" get logged when the record expires in 5 seconds, however instead, I see "foo" and "bar."
How can I properly remove the pre-existing subscriber.on('message') listeners?
If I understand your question correctly. I think this is not a Redis related problem, it's just an application-level problem. You only need to call subscriber.subscribe once to set up a subscription. You want to support only one callback, so store that callback internally. And every time setOnExpire get called, just replace the callback with a new one. I'm not a JavaScript expert, bellow code snippet works fine on my computer:
var redis = require("redis");
var bluebird = require('bluebird');
bluebird.promisifyAll(redis);
var client = redis.createClient();
var subscriber = redis.createClient();
const setOnExpire = function() {
var notify_on = false;
var promise;
var callback = function(key) { };
return (onExpire) => {
if (notify_on) {
promise.then(()=> {
callback = onExpire;
});
} else {
promise = new Promise((resolve, reject) => {
notify_on = true;
client.config('set', 'notify-keyspace-events', 'Ex', () => {
resolve();
});
});
promise.then(() => {
subscriber.subscribe('__keyevent#0__:expired', () => {
subscriber.on('message', function (channel, key) {
callback(key);
});
});
});
}
};
}();
setOnExpire(() => { console.log('foo'); });
setOnExpire(() => { console.log('bar'); }); // my intention is to replace the callback that logs "foo"
client.hmsetAsync('hello', 'yesl', 'thankyou').then(() => {
client.expireAsync('hello', 5);
});
I am using react-native-linkdin-login library to support linkding sigin in my application.It is working properly in android but in iOS it always ask to download an application rather than application already exist in device and redirect to the APP store. When I open and login to linkdin account, I can't come back to my react-native application, with user profile details.
Give me any suggestion as soon as possible.
async componentWillMount() {
LinkedinLogin.init(
[
'r_emailaddress',
'r_basicprofile'
]
);
}
async handleLinkedinLogin(){
LinkedinLogin.login().then((user) => {
alert("linkdin");
this.setState({ user : user });
this.getUserProfile();
}).catch((e) => {
var err = JSON.parse(e.description);
alert("ERROR: " + err.errorMessage);
alert('Error', e);
});
return true;
}
getUserProfile(user) {
LinkedinLogin.getProfile().then((data) => {
const userdata = Object.assign({}, this.state.user, data);
this.setState({ user: userdata });
const Email = userdata.emailAddress;
const Fullname = userdata.firstName+' '+userdata.lastName;
const SocialAppId = userdata.id;
const SignupType = 'Linkedin';
alert("Please wait....")
this.socialLogin(Fullname,Email,'null',SignupType);
}).catch((e) => {
alert(e);
});
}
