Swipable is not working in Android (Expo Cli)

import {Swipeable} from 'react-native-gesture-handler' not working in android (expo Cli). I've tried everything, ejected expo cli, edited MainActivity.java file but nothing works. There are a couple of threads but none of them works. Please help as I'm stuck with this issue for a long time. Thanks

You have to wrap the swipeable in a gestureHandlerRootView
import { GestureHandlerRootView, Swipeable } from "react-native-gesture-handler";
<GestureHandlerRootView>
<Swipeable renderRightActions={(_, dragX) => this.rightActions(dragX, index)}>
<View style={styles.todoContainer}>
<TouchableOpacity onPress={() => this.toggleTodoCompleted(index)}>
<Ionicons
name={todo.completed ? "ios-square" : "ios-square-outline"}
size={24}
color={"#A4A4A4"}
style={{ width: 32 }}
/>
</TouchableOpacity>
<Text
style={[
styles.todo,
{
textDecorationLine: todo.completed ? "line-through" : "none",
color: todo.completed ? "#A4A4A4" : "#2D3436"
}
]}
>
{todo.title}
</Text>
</View>
</Swipeable>
</Swipeable>

How we get exif metadata info before capturing Image in React Native

I am trying to get EXIF Metadata informations before capturing Image. I am using React Native Camera library for implementing camera and their properties for defaults settings. In my point of view after capturing only i am getting EXIF metadata value in both Android and iOS. React native camera documentation link.

In Native iOS we get live metadata using CMSampleBuffer delegate. Is there any possibility to get Exif data before taking pictures.

Problem: Why react native video does not play video in full screen?

I am creating an application for android and ios in react-native(0.57.7) and using react-native-video to play videos uploaded into vimeo. After integrate react video plugin, tested in both device. In ios it works perfectly but in android, I am not able to play video in full-screen mode. Here is my code for Android:

Please help, What I'm doing wrong ?

I have solved fullscreen of video frame just adding resizeMode on Video component:
<Video source={{ uri:this.state.videoFileArr[0].link}} // Can be a URL or a local file.
ref={ ref =>
this.player = ref
} // Store reference
onBuffer={this.onBuffer} // Callback when remote video is buffering
onError={this.videoError} // Callback when video cannot be loaded
style={styles.backgroundVideo}
controls={true}
paused={false}
fullscreen={true}
resizeMode="cover"
/>

I was struggling with the same problem couple of days ago but I made it work for me in android. I hope this will help you also.
You will need to install some other package as well that is
1. react-native-video-controls
2. react-native-orientation
now In your Screen where the video will be played.

Most of suggestion involves adding additional libraries to achieve fullscreen in react-native-vide for android. Its not really needed.
What we need is set the height and width of to full screen to achieve this. we need to use variable instead of fixed value then setState to refresh the view.
Below is the sample typescript code that works for react-native-video fullscreen:
import React, {Component} from 'react';
import {
View,
StyleSheet,
TouchableWithoutFeedback,
Dimensions,
} from 'react-native';
import Video from 'react-native-video';
import Icon from 'react-native-vector-icons/FontAwesome';
import MaterialIcon from 'react-native-vector-icons/MaterialCommunityIcons';
interface Props {}
interface States {
paused: boolean;
inFullScreen: boolean;
}
export default class Sandbox extends Component<Props, States> {
player: any;
videoStyle: {minWidth: number; minHeight: number};
constructor(props: Props) {
super(props);
this.state = {
paused: true,
inFullScreen: false,
};
this.videoStyle = {minWidth: 400, minHeight: 400};
}
render() {
return (
<View style={{height: 400, width: 400}}>
<Video
source={{
uri:
'https://www.radiantmediaplayer.com/media/big-buck-bunny-360p.mp4',
}} // Can be a URL or a local file.
ref={(ref: any) => {
this.player = ref;
}} // Store reference
controls={false}
paused={this.state.paused}
resizeMode={'cover'}
style={this.videoStyle}
/>
<View style={styles.controls}>
<TouchableWithoutFeedback
onPress={() => {
this.setState({paused: !this.state.paused});
}}>
<Icon name={'play'} size={30} color="#FFF" />
</TouchableWithoutFeedback>
<TouchableWithoutFeedback
onPress={() => {
if (!this.state.inFullScreen) {
//Orientation.lockToLandscape();
this.videoStyle = {
minHeight: Dimensions.get('window').height,
minWidth: Dimensions.get('window').width,
};
} else {
this.videoStyle = {
minHeight: 400,
minWidth: 400,
};
}
this.setState({inFullScreen: !this.state.inFullScreen});
}}>
<MaterialIcon name={'fullscreen'} size={30} color="#FFF" />
</TouchableWithoutFeedback>
</View>
</View>
);
}
}
const styles = StyleSheet.create({
controls: {
backgroundColor: 'rgba(0, 0, 0, 0.5)',
height: 48,
top: 20,
left: 0,
bottom: 0,
right: 0,
position: 'absolute',
flexDirection: 'row',
alignItems: 'center',
justifyContent: 'space-around',
paddingHorizontal: 10,
},
});

As #Selva answered we can use variables for video sizes i.e width & height and make it occupy full screen and use a stack to place the video in a stack screen above the current screen and pop it when needed. Even if it's in a flat list.

Had same issue fix it by removing the wrapping and setting just the height to the player, no other library needed and no need to manage the orientation.
<Video source={{uri: this.props.videoData.uri}}
onEnd={this.onVideoEnd}
style={styles.player}
controls={true} />

<View
onStartShouldSetResponder={() => setPaused(!paused)}
style={{
marginHorizontal: 10,
backgroundColor: "black",
position: "relative",
transform: [{ rotate: "90deg" }],
// justifyContent:'center',
// alignItems:'center'
}}
>
<Video
onEnd={onEnd}
onLoad={onLoad}
onLoadStart={onLoadStart}
posterResizeMode={"cover"}
onProgress={onProgress}
paused={paused}
ref={(ref) => (videoPlayer.current = ref)}
resizeMode={'stretch'}
source={{
uri: "url",
}}
style={{
...styles.backgroundVideo,
height: width,
aspectRatio:2
// width: "100%"
// alignSelf:'center'
// transform: [{ rotate: '90deg'}]
}}
/>

just give it a width of
width:'100%'

Use import TouchID from 'react-native-touch-id' on top of the js file.

KeyBoardAvoidingView hides content

enter image description here
Current Behaviour
The KeyBoardAvoidingView hides the Login button.
Its the same on Android and on iPhone.
On an Android Tablet It hides the Login button but since the screen is large you can see the button halfway from the top.
Expected Behaviour
I want the Login button at the bottom to move into the app frame when user wants to input his login details.
App.js

import { StyleSheet, Text, View,TouchableOpacity, AppRegistry} from 'react-native';

The problem is that KeyboardAvoidingView cannot correctly apply padding if it's children doesn't have plain size set. In this particular case you need to figure out the screen dimenson and apply screen height (minus navigation bar height) to your root View style:
import { Dimensions } from 'react-native';
const { screenHeight: height } = Dimensions.get('window');
const styles = StyleSheet.create({
...
containerContent: {
height: screenHeight - navBarHeight,
justifyContent: 'center',
}
...
},
And apply it in your render method:
render() {
return (
<KeyboardAvoidingView behavior="padding" style={styles.container}>
<View style={styles.containerContent}>
...
</View>
</KeyboardAvoidingView>
);
}

I am still seeing that on keyboard open the toolbar is being pushed up out of visible area. This is the code :
<KeyboardAvoidingView style={styles.containerContent}>
<View style={styles.containerContent}>
<GiftedChat
messages={}
onSend={this.onSend}
renderAvatar={null}
user={{
_id: 1,
}}
imageStyle={{}}
/>
</View>
</KeyboardAvoidingView>
const styles = StyleSheet.create({
containerContent: {
height: Dimensions.get('window').height - kHeaderHeight,
justifyContent: 'center',
flex: 1,
},
});
