React Native android permission is not showing

The react native android permission pop-up is not showing, I cannot download a file. It works on a simulator but not on a real phone.
Here is my permission function :
const requestAndroidStoragePermission = async () => {
try {
const granted = await PermissionsAndroid.request(
PermissionsAndroid.PERMISSIONS.WRITE_EXTERNAL_STORAGE,
{
title: "File access",
message:
"The app needs files access to download your performance.",
}
);
if (granted === PermissionsAndroid.RESULTS.GRANTED) {
this.setState({ storagePermission: true });
this.setState({ showExportModal: true });
} else {
console.log("Files permission denied");
}
} catch (err) {
console.warn(err);
}
};
I have the permission on my AndroidManifest.xml :
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"
android:targetSdkVersion="29" />
Someone have an idea ?

react-native-image-picker launchCamera in not working in android

I'm using "react-native-image-picker": "^3.0.1" in react native for capture image. but I got error while opening the camera in android 9.
I got error :
{"errorCode": "others", "errorMessage": "This library does not require Manifest.permission.CAMERA, if you add this permission in manifest then you have to obtain the same."}
here is my code
ImagePicker.launchCamera(
{
includeBase64: false,
mediaType: 'photo',
quality: 0.8,
},
async (response) => {
if (response.didCancel) {
console.log('User cancelled image picker');
} else if (response.error) {
console.log('ImagePicker Error: ', response.error);
} else {
}
},
);

Before capturing image, ask camera permission to user. In Android above marshmallow version you should ask Run Time permission as well which are called dangerous permission.
const requestCameraPermission = async () => {
try {
const granted = await PermissionsAndroid.request(
PermissionsAndroid.PERMISSIONS.CAMERA,
{
title: "App Camera Permission",
message:"App needs access to your camera ",
buttonNeutral: "Ask Me Later",
buttonNegative: "Cancel",
buttonPositive: "OK"
}
);
if (granted === PermissionsAndroid.RESULTS.GRANTED) {
console.log("Camera permission given");
} else {
console.log("Camera permission denied");
}
} catch (err) {
console.warn(err);
}
};
And then if permission granted then inside if call
ImagePicker.launchCamera

We need to add run time permissions for the react-native-image-picker . We also need to add seperate permission request for camera and external storage as.please check out below code worked for me .
const grantedcamera = await PermissionsAndroid.request(
PermissionsAndroid.PERMISSIONS.CAMERA,
{
title: "App Camera Permission",
message:"App needs access to your camera ",
buttonNeutral: "Ask Me Later",
buttonNegative: "Cancel",
buttonPositive: "OK"
}
);
const grantedstorage = await PermissionsAndroid.request(
PermissionsAndroid.PERMISSIONS.WRITE_EXTERNAL_STORAGE,
{
title: "App Camera Permission",
message:"App needs access to your camera ",
buttonNeutral: "Ask Me Later",
buttonNegative: "Cancel",
buttonPositive: "OK"
}
);
if (grantedcamera === PermissionsAndroid.RESULTS.GRANTED && grantedstorage === PermissionsAndroid.RESULTS.GRANTED) {
console.log("Camera & storage permission given");
var options = {
mediaType: 'photo', //to allow only photo to select ...no video
saveToPhotos:true, //to store captured photo via camera to photos or else it will be stored in temp folders and will get deleted on temp clear
includeBase64:false,
};
launchCamera (options, (res) => {
console.log('Response = ', res);
if (res.didCancel) {
console.log('User cancelled image picker');
} else if (res.error) {
console.log('ImagePicker Error: ', res.error);
} else if (res.customButton) {
console.log('User tapped custom button: ', res.customButton);
alert(res.customButton);
} else {
// let source = res;
// var resourcePath1 = source.assets[0].uri;
const source = { uri: res.uri };
console.log('response', JSON.stringify(res));
setImageSource(source.uri);
}
});
} else {
console.log("Camera permission denied");
}

this helps me
add option to android\app\src\main\AndroidManifest.xml -> section application
-> param android:requestLegacyExternalStorage="true"
android\app\src\main\AndroidManifest.xml
...
<application
...
android:requestLegacyExternalStorage="true"
...>

How to know if the android request permission dialog is shown

Here shows the example on how to use PersmissionAndroid in react native:
https://facebook.github.io/react-native/docs/permissionsandroid
import { PermissionsAndroid } from 'react-native';
async function requestCameraPermission() {
try {
const granted = await PermissionsAndroid.request(
PermissionsAndroid.PERMISSIONS.CAMERA,
{
'title': 'Cool Photo App Camera Permission',
'message': 'Cool Photo App needs access to your camera ' +
'so you can take awesome pictures.'
}
)
if (granted === PermissionsAndroid.RESULTS.GRANTED) {
console.log("You can use the camera")
} else {
console.log("Camera permission denied")
}
} catch (err) {
console.warn(err)
}
}
How to know if this dialog is really shown? Because there are times that the user has already approved the permission and the next it call this functions, it will not show anymore and just return the granted results.
How to know if the user has really clicked on the Deny and Allow buttons?

react-native on android crash when requesting camera permissions

my phone (android 8.1.0) keeps crashing when i request the permission to use the camera in react native. I use android:targetSdkVersion="25" in my Android Manifest.
componentDidMount(){
(async () => {
await this.requestCameraPermission();
})();}
async requestCameraPermission() {
try {
const granted = await PermissionsAndroid.request(
PermissionsAndroid.PERMISSIONS.CAMERA,
{
'title': 'Cool Photo App Camera Permission',
'message': 'Cool Photo App needs access to your camera ' +
'so you can take awesome pictures.'
}
)
if (granted === PermissionsAndroid.RESULTS.GRANTED) {
console.log("You can use the camera")
} else {
console.log("Camera permission denied")
}
} catch (err) {
console.warn(err)
}
}

How do I request permission for Android Device Location in React Native at run-time?

I have been trying to use React Native 's GeoLocalisation for an Android App. The poorly documentated module is found here https://facebook.github.io/react-native/docs/geolocation.html.
According to the documentation, you handle location permissions on Android using the following code in the AndroidManifest.xml file
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
However, my online research suggests that the above line of code is useless for versions of ANDROID >= 6.0
As my implementation of GeoLocation is not currently working, I have no other reason but to believe that location permissions are not correctly handled.
How do I successfully request location permission at run-time for React Native Android App?

I solved it by changing the targetSdkVersion ( same to compileSdkVersion, in my case 23) in android/app/build.gradle.
Edit AndroidManifest.xml located in android/src/main and add the
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
next :
import { PermissionsAndroid } from 'react-native';
and then add this method:
export async function requestLocationPermission()
{
try {
const granted = await PermissionsAndroid.request(
PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION,
{
'title': 'Example App',
'message': 'Example App access to your location '
}
)
if (granted === PermissionsAndroid.RESULTS.GRANTED) {
console.log("You can use the location")
alert("You can use the location");
} else {
console.log("location permission denied")
alert("Location permission denied");
}
} catch (err) {
console.warn(err)
}
}
and access the method when you request the location at run-time
async componentWillMount() {
await requestLocationPermission()
}

This did not work for me
if (granted === PermissionsAndroid.RESULTS.GRANTED) {
}
I referred to https://facebook.github.io/react-native/docs/permissionsandroid.html#request
and check() return a boolean
const granted = await PermissionsAndroid.check( PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION );
if (granted) {
console.log( "You can use the ACCESS_FINE_LOCATION" )
}
else {
console.log( "ACCESS_FINE_LOCATION permission denied" )
}

You could use the react native PermissionsAndroid to request the permission: https://facebook.github.io/react-native/docs/permissionsandroid.html#request
Or, an easier option will be using a library that does it for you, such as https://github.com/yonahforst/react-native-permissions

I've noticed two things:
You have to change compileSdkVersion 23 in build.gradle file
You have to add your View's click listener to display to Permission dialog.
Sample code:
import React, { Component } from 'react';
import { Text, PermissionsAndroid, Alert } from 'react-native';
export default class RuntimePermissionSample extends React.Component {
constructor(props) {
super(props);
}
async requestLocationPermission() {
const chckLocationPermission = PermissionsAndroid.check(PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION);
if (chckLocationPermission === PermissionsAndroid.RESULTS.GRANTED) {
alert("You've access for the location");
} else {
try {
const granted = await PermissionsAndroid.request(PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION,
{
'title': 'Cool Location App required Location permission',
'message': 'We required Location permission in order to get device location ' +
'Please grant us.'
}
)
if (granted === PermissionsAndroid.RESULTS.GRANTED) {
alert("You've access for the location");
} else {
alert("You don't have access for the location");
}
} catch (err) {
alert(err)
}
}
};
render() {
return (
<Text
onPress={() => this.requestLocationPermission()}>
Request Location Permission
</Text>
)
}
}
Hope this would help you.

You can ask location permission using following code
try {
const granted = await PermissionsAndroid.request(
PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION
)
if (granted === PermissionsAndroid.RESULTS.GRANTED) {
alert("You can use the location")
} else {
alert("Location permission denied")
}
} catch (err) {
console.warn(err)
}
alert('hi');

in Manifest
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.CAMERA"/>
