Hi everyone, I’m experiencing issues with running Android applications on a device with an Intel Evo processor. Despite meeting the system requirements, the applications either fail to launch or exhibit performance problems. I’ve tried updating drivers and checking compatibility settings, but the problem persists. Has anyone else encountered similar issues with Intel Evo processor and Android applications? What troubleshooting steps or solutions have worked for you? Any advice or insights would be greatly appreciated! Thanks in advance for your help! Alisa

When running the React Native application, in this application folder, open cmd and type: Node server.js to connect to the sql server data. Next, open Visual Studio Code and run the npm start command, if you run the npm start command without running the command before. Node server.js will report a data connection error. Can you declare the node server.js command to run before running the npm start command ?
var express = require('express'); var app = express(); var sql = require("mssql"); I declare the above library in React Native when running the error: Android Bundling failed 3690ms (D:\demo\node_modules\expo\AppEntry.js) The package at "node_modules\mssql\lib\base\connection-pool.js" attempted to import the Node standard library module "node:events". It failed because the native React runtime does not include the Node standard library.
I use windows authentication but when the username didn't have permissions, I got a different error var sql = require('mssql/msnodesqlv8'); const config = { user: 'sa', password: 'Coffee', server: 'localhost', database: 'Cafe', driver: 'msnodesqlv8', port: 1433, options: { trustedConnection: true, enableArithAbort: true } }; const conn = new sql.ConnectionPool(config).connect().then(pool => { return pool; }); When I connect to the internal server, I get an error: ConnectionError: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified at PrivateConnection.callback2 (D:\NodeJS\node_modules\mssql\lib\msnodesqlv8\connection-pool.js:46:17) at Immediate.<anonymous> (D:\NodeJS\node_modules\msnodesqlv8\lib\connection.js:41:14) at process.processImmediate (node:internal/timers:478:21) { code: undefined, originalError: [Error: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified] { sqlstate: 'IM002', code: 0, severity: 0, serverName: '', procName: '', lineNumber: 0 } }
I created a Login application that connects to the sql server using Visual Studio Code. The Login and SignUp application logs into the sql server to read the Table 'TABUSERNAME' and export it to the grid, but I get an error, my computer's sql server information: user: 'sa' pass: 'Coffee' server:'MICROSOFT' or '192.168.1.100' database: 'Cafe' Can you please fix my code errors ? File: App.js

Visual Studio Code fails to update strings when running virtual machine. I have installed the Android Studio virtual machine and Visual Studio Code when running the virtual machine to export the string normally, but when I edit the string it does not update again, I have to restart the machine to update the string, how can I fix this error? Here is my simple code example: App.js import React from 'react' import { StyleSheet, Text, View } from 'react-native' const App = () => { return ( <View style={styles.container}> <View style={styles.top}> <Text style={styles.topText}>Top Left</Text> //I edited this thread ??? </View> </View> ) } export default App const styles = StyleSheet.create({ container: { }, top: { marginTop : 80, marginHorizontal : 40, backgroundColor : 'pink', paddingVertical : 20, paddingHorizontal : 20, borderWidth : 1, borderColor : 'red' }, topText: { fontSize : 20, color : 'blue', fontWeight : 'bold' } })
