微笑、不失礼 提交于 2019-11-30 12:55:29
I am trying to Implement AWS-IoT(device) using React-Native. I have used the packages, 1) aws-iot-device-sdk-js 2) react-native-aws-iot-device-shadows and got a lot of errors while using the package. I could debug few, but did not get expected results. I am Implementing AWS-IoT for Chatting application. I am successfully creating an IoT session using REST APIs and get these as responses iotEndpoint, region, accessKey, secretKey, sessionToken . But using these credentials I am unable to Connect using the above packages. I figured this out, Step 1: Install aws-iot npm package npm install --save

React native Android ScrollView scrollTo not working

空扰寡人 提交于 2019-11-30 08:19:30
I am trying to use a horizontal ScrollView in React Native for Android, where the starting position is in the middle of the scrolling images rather than (0,0). The scrollTo method seems to be called correctly inside componentDidMount but nothing moves in the application, it still shows as starting the scroll all the way to the left. Since this is Android I don't have access to contentOffset props or I would set that directly, according to the documentation. Here is the code: 'use strict'; var React = require('react-native'); var { StyleSheet, View, Text, ScrollView, Component, } = React; var
