Description
Some https URLs request fails on android 4 with no error while it's working on other androids (I've tested on some phones and it fails on 4.4.2 while successful on 5.0.2, 6.0.1, 9)
Reproducible Demo
Create a project and paste the following code into your App.js. Make sure you are running on a device with android 4.4.2. It seems working on android 5+.
import React, {Component} from 'react';
import {Text, View} from 'react-native';
export default class App extends Component {
componentDidMount() {
/* this request fails on android 4 while its working on android 5+*/
fetch('https://jsonplaceholder.typicode.com/posts/1')
.then(resp => resp.json())
.then(json => alert(`fail -> ${JSON.stringify(json)}`))
.catch(err => {
console.log(err)
})
/* this one is successful even on android 4 */
fetch('https://www.json-generator.com/api/json/get/clfvuKZzOq?indent=2')
.then(resp => resp.json())
.then(json => alert(`success -> ${JSON.stringify(json)}`))
}
render() {
return (
<View style={{flex: 1, justifyContent: 'center', alignItems: 'center'}}>
<Text>https error on android 4</Text>
</View>
);
}
}
