Unable to connect to SQLite in React-Native

I have pre-defined sqlite database using DB Browser for SQLite. I have place the db file in the path root/android/app/src/main/assets/www/mysqlite.db, unfortunately I'm unable to
connect. Below are my versioning.
Samsung Galaxy Android 11,
"react-native-sqlite-storage": "^6.0.1",
"react": "17.0.2",
"react-native": "0.65.1",
"#react-navigation/native": "^6.0.4",
My script(I make it simplified):
import SQLite from 'react-native-sqlite-storage';
SQLite.DEBUG(true);
SQLite.enablePromise(false);
export const AppSignIn = (props) => {
const OpenDB = () => {
return new Promise((resolve, reject) => {
global.db = SQLite.openDatabase(
{
name: 'mysqlite.db',
createFromLocation: '~mysqlite.db',
},
() => {
console.log("Connection success!");
},
error => {
console.log(error);
reject();
});
resolve();
});
}
const ReadDB = () => {
return new Promise((resolve) => {
global.db.transaction(function (tx) {
tx.executeSql(
// The rest of the trx
);
resolve();
});
});
}
async function ConnectDB() {
return new Promise(async (resolve, reject) => {
await OpenDB()
.then(async () => {
await ReadDB()
.then(() => {
console.log('YEAY FINALLY');
resolve();
})
})
.catch((error) => {
console.log(error);
reject();
});
});
}
React.useEffect(() => {
(async () => {
await ConnectDB()
.then()
.catch();
})();
}, []);
}
The log writes:
LOG OPEN database: mysqlite.db
LOG SQLite.open({"name":"mysqlite.db","createFromLocation":"~mysqlite.db","dblocation":"nosync","assetFilename":"~mysqlite.db"})
LOG new transaction is waiting for open operation
LOG Phone connected? true, Server connected? true
LOG OPEN database: mysqlite.db failed, aborting any pending transactions
LOG [Error: Could not open database]
I have tried several ways but I'm unable to connect to it.
Move from www to assets folder directly. Uninstall app on phone and run again.
Remove SQLite.enablePromise(false);
react-native link react-native-sqlite-storage
cd android && ./gradlew clean
Follow step to opendatabase call

Try moving your file for android from root/android/app/src/main/assets/www/mysqlite.db -> root/android/app/src/main/assets/mysqlite.db

I finally able to run it on Samsung Galaxy with Android 11. I've tried on Redmi6 with Android 9 and it can run.
I've removing react-native.config.js which contain SQLite
module.exports = {
dependencies: {
"react-native-sqlite-storage": {
platforms: {
android: {
sourceDir: "../node_modules/react-native-sqlite-storage/platforms/android-native",
packageImportPath: "import io.liteglue.SQLitePluginPackage;",
packageInstance: "new SQLitePluginPackage()"
}
}
}
}
};
I also remove the import module import io.liteglue.SQLitePluginPackage; in MainApplication.java and the database finally open.
I'm not sure if this way are absolute. I hope it was temporary as it oppose the way from the tutorial.

deviceNotReady error : "Registration failed" react-native-twilio-programmable-voice

I am working on react native application and want to integrate the Phone masking feature like Uber do. I have choosen Twilio Phone Masking for this. I have used react-native-twilio-programmable-voice package.
I have integrated this using this link:: https://medium.com/#edzh1/create-a-twilio-voip-calls-in-a-react-native-app-35a729a9613d
I have done server setup successfully, using php. But getting error deviceNotReady error : "Registration failed". I have no idea what I am doing wrong here.
This is initial function I am calling here::
initTwilio = async () => {
const token = await this.getAuthToken();
if (Platform.OS === 'android') {
await this.getMicrophonePermission();
}
const success = await TwilioVoice.initWithToken(token);
if (success.initialized) {
TwilioVoice.addEventListener('deviceReady', () => {
this.setState({ twilioInited: true });
});
TwilioVoice.addEventListener('deviceNotReady', function (data) {
console.log('data', data) // getting error here
});
if (Platform.OS === 'ios') { //required for ios
TwilioVoice.configureCallKit({
appName: 'ReactNativeTwilioExampleApp',
});
}
}
};
getAuthToken = () => {
return fetch('https://myurl/accessToken.php', {
method: 'get',
})
.then(response => response.text())
.catch((error) => console.error(error));
}
Please help, and suggest me what I am doing wrong here.

Share custom file using React Native

I have a custom file something like file.myext which I create it using rn-fetch-blob:
RNFetchBlob.fs.writeFile(path, JSON.stringify(data), 'utf8')
And I'm using react-native-share to share the file,
I tried both:
Share.open({type: 'text/plain', url: 'file://'+path})
and
RNFetchBlob.fs.readFile(path, 'base64')
.then((data) => {
Share.open({url: 'data:text/plain;base64,'+data})
})
but doesn't work, the second one share .txt file.
anyway to solve this?

Might help, when I was also looking into this, using react-native-fs I was able to do:
var path = RNFS.DocumentDirectoryPath + '/test.txt';
RNFS.writeFile(path, 'test', 'utf8')
.then(() => {
console.log('FILE WRITTEN!');
Share.open({
url: 'file://' + path,
})
.then(res => {
console.log(res);
})
.catch(err => {
err && console.log(err);
});
})
.catch(err => {
console.log(err.message);
});

How to set timeout react-native api call using fetch(GET Call)?

This my code(used to fetch data).
loadApi() {
this.setState({isListLoaded : true})
return fetch('http://www.androidbegin.com/tutorial/jsonparsetutorial.txt')
.then((response) => response.json())
.then((responseJson) => {
this.setState({listView : responseJson.worldpopulation})
this.setState({isListLoaded : false})
ToastAndroid.show('A pikachu appeared nearby !', ToastAndroid.SHORT);
})
.catch((error) => {
console.error(error);
});
}
How can i set a timeout to this specific syntax ?.Please share the code part if you have any.

There is no standard way till now according to this github thread.
However there is one solution, use whatwg-fetch-timeout
sample code :
return fetch('/path', {timeout: 500}).then(function() {
// successful fetch
}).catch(function(error) {
// network request failed / timeout
})

Linking event handler not fired when app is in background

I am implementing logging in using Facebook, Twitter, etc.. When the user clicks on the icon, safari opens, the user logs in, and then the webpage redirects to appname://login.
I followed this article https://medium.com/react-native-training/deep-linking-your-react-native-app-d87c39a1ad5e, and my code looks like the following:
componentDidMount(){
Linking.getInitialURL()
.then((url) => {
if (url) {
// Alert.alert('GET INIT URL','initial url ' + url)
this.resetStackToProperRoute(url)
}
})
.catch((e) => {})
Linking.addEventListener('url', this.handleOpenURL);
}
componentWillUnmount() {
Linking.removeEventListener('url', this.handleOpenURL);
}
handleOpenURL = (event) => {
console.log('event: ' + event);
}
The problem is nothing gets printed on the console. I think the problem is that the handler is not fired when the app comes from the background. Is there a way around it?
thanks
