React native inlineImageLeft value - react-native

I want to know the proper value for inlineImageLeft prop. in react native <TextInput> component. Can any one help me?
I copied the image in drawable folder.
<TextInput
autoCapitalize= {'words'}
autoFocus={true}
caretHidden = {false}
keyboardType={'url'}
defaultValue={'Hello!'}
placeholder={'hello world'}
placeholderTextColor= {'red'}
returnKeyType = {'send'}
secureTextEntry={true}
selectTextOnFocus={false}
inlineImageLeft="user"
/>

Create Drawable folder inside android res directory . Copy the image say image.png in that folder. Then use in TextInput component.
inlineImageLeft="image"
If image is not showing just uninstall the previous app and rerun the project.

From the React Native github page:
<TextInput
inlineImageLeft="ic_menu_black_24dp"
placeholder="This has drawableLeft set"
style={styles.singleLine}
/>

You can find an example in UIExplorer in react-native. In this example the inlineImageLeft prop used this way:
<TextInput inlineImageLeft="ic_menu_black_24dp"/>
Example is in:
react-native/Examples/UIExplorer/js/TextInputExample.android.js
It seems path should be relative to ./android/app/src/main/res/drawable/. Any other path does not work. Also image does not scale.

I also can't see the icon inside TextInput.
Then, I try to uninstall and reinstall App.
I got the build failed error:
What went wrong: Execution failed for task ':app:mergeDebugResources'.
C:\Users\yusuf\git\App3\android\app\src\main\res\drawable\search.ico:
Error: The file name must end with .xml or .png
Then, I changed my file type from .ico to .png
Image should be in the "drawable" folder.
<TextInput
style={styles.modalInput}
autoFocus ={true}
inlineImageLeft='search'
inlineImagePadding={5}
placeHolder ="Search Product"
placeholderTextColor="white"
onChangeText={ (text) => this.setState({text})}
value = {this.state.text}
/>
With the above change, it works now.

Downloadinf PDF from React native webview gives "invaild pdf format or corrupted" after opening on Android but works fine on iOS

I'm using the below code to open an URL. Downloading a PDF from React native webview after opening on Android gives:
"invaild pdf format or corrupted"
but it works fine on iOS.
<WebView
renderToHardwareTextureAndroid={true}
startInLoadingState={isLoading}
renderLoading={() => {
return <BarIndicator color="blue" />;
}}

javaScriptEnabled={true}

pdf doesn't work on android webview check this issue here you may look for other solution like download it and open it with pdf viewer
Seems to be a very well known 5 year old problem
https://react-native.canny.io/feature-requests/p/android---webview-cannot-display-pdf
that needs saveas file.pdf then either call the native pdf handler
or
embed/customise a simple maintained js viewer such as

Why my images aren't showing in React Native

I'm trying to show some images in my React Native app. It's a simple app, only for Android. The app get informations from an API. The initial View is a list of items and when I click in one item, it gets more info from the API and show in a new page. I also get some urls that points to images that are kept in a S3 bucket in AWS.
This is how I show the images:
<ScrollView>
{this.state.urls.map(url => {
<Image
source={{uri: url}}
style={{width:400, height:200}}
/>
}
</ScrollView>
The problem is that it's not showing those images. I can see that there is a part of the page that is for the image. I can see that because if a put the image first and after that some text, the text will appear at the bottom of the page. I don't know what is going on that the image doesn't appear.
I searched for an answer, found something about using https instead of http (at least for iOS). Found that I need to set width and height. I already did those things and others but it's not working.
I also tried just picking a image from the internet and putting it url direct in uri but it still doesnt't work.
You're missing a return statement in your map function.
<ScrollView>
{this.state.urls.map(url => {
return <Image
source={{uri: url}}
style={{width:400, height:200}}
/>
}
</ScrollView>
UPDATE
I just tried the url that you provided in the above comment and it doesn't work on my device. I tried a different image from the internet this one and it works. There may also be something that is stopping you from accessing the images from within a mobile app.
To debug further I try would a single <Image .../> with the image hosted on AWS and see if you can get that to show. There may need to be some AWS configuration that you need to change to allow the image to be accessed from a mobile device.
Assuming your image URLs are accessible in your application.
The below code will show your images. Actually you forgot to return a component from the map which is a must have.
<ScrollView>
{this.state.urls.map(url => {
return <Image
source={{uri: url}}
style={{width:400, height:200}} /> }
}
</ScrollView>

Possibility of loading Google places images in react-native Image component?

I am trying to find a way to load image reference I get from places api into places photo API using Image component of react-native like below,
const imageLink = 'https://maps.googleapis.com/maps/api/place/photo?maxwidth=400&photoreference=CmRaAAAAuZ36wzrMYCVNWM1smQkRKuQyXecPgRpcsMfrSqbJM0EUTXZ62j8Ljxtk8HsxohXbtAwZAwmj_F3HmDwLoQaH9qt2TZJhhA6EuXK41UFo0Ow750MJujtrr5hgHR2lF7EXEhCkWj_dZ4LefrYzLU1_5RF1GhTR7Ggem5IJ-v7V2U8fjKoU9tBUOg&key=--MyKey--'
return (
<View >
<TouchableHighlight >
<View>
<Image
style={{width:64, height:64,flex:1,backgroundColor:'red'}}
source={{uri: imageLink}}
/>
</View>
</TouchableHighlight>
</View>
);
I am getting only empty placeholder with above code. However, I am able to load this link in browser.One caveat is that google places photo's link is redirecting to some other url which then displays image in browser. Am I doing it right? or is there any other way I can accomplish the same. Note: I tried react-native-network-image library as well.
You can have a look at the ImagePrefetch function in googleplace module:
https://github.com/srirangan/googleplaces.js/blob/master/test/ImageFetchTest.js
However, I am having issue with the whole module at the moment because of the line var https = require("https"); called in this specific function.
Not sure if it's an issue with new version of RN (upgraded to 0.55 recently) or just some other error in my new setup.
This worked perfectly in previous RN (was running on 0.48)

React-Native-Element icon shows up as cross in search bar

How do I change the icon of search bar in react-native-element.
<Icon type='font-awesome' name="share-alt" size={33} color="red" />
The above code does render the icon properly.
But the same icon shows up as a cross in the following code
<SearchBar
lightTheme
icon = {"share-alt", "red"}
inputStyle={{margin: 0, padding:3, flex:1}}
containerStyle={{flex:1, height:undefined}}
onChangeText={() => {}}
placeholder='ABC' />
You can only change native icon only. It's list in here https://material.io/icons/.
icon prop does not accept type . It is specify here react-native-elements/API/searchbar/
object {name (string), color (string), style (object)}
According to your screen shots, react-native-vector-icons is not installed properly.
1. Install react-native-vector-icons correctly.
2. And then you can see search icon. At that time, you can change the icon of search bar. You can use Material icon names
Make sure you have linked the vector icons after installing them
npx react-native link react-native-vector-icons
Then make sure you stop your packager and recompile the app again. now the icons should show up. The icons are not usually loaded up after installing and linking, you must recompile the app again.

Can't load image from props

Somehow the location of my image is not found load it from props.
This works
let overview_bg = require('../../images/locaties/placeholder.png');
<Image source={overview_bg} style={styles.overview_bg}>
But when I get the url from props it doesn't:
let overview_bg = require(this.props.image);
<Image source={overview_bg} style={styles.overview_bg}>
this.props.image has the exact same url which gives me the error:
Requiring unknown module "../../images/locaties/placeholder.png". If
you are sure the module is there, try restarting the packager or
running "npm install"
I have checked the url multiple times it is exactly the same. I also tested it in console.log
The prop is given from another container which gets it from the store.
From the React Native Image documentation:
Note that in order for this to work, the image name in require has to be known statically.
// GOOD
<Image source={require('./my-icon.png')} />
// BAD
var icon = this.props.active ? 'my-icon-active' : 'my-icon-inactive';
<Image source={require('./' + icon + '.png')} />
// GOOD
var icon = this.props.active ? require('./my-icon-active.png') : require('./my-icon-inactive.png');
<Image source={icon} />
