I am able to create pdf in my ionic app and if I run the app in chrome it opens perfectly. However if I install my app on the android device it doesn't open. Below is my code. Can someone please help me if I have to do something extra to open it on device. I want to open it with default pdf application on device.
pdfMake.createPdf(dd).open();
Ok. After banging my head on wall for 3 days I finally found the solution and sharing here so that other people who are facing this issue can get help. I am creating pdf and saving it using cordova file plugin. After successful save I am opening it in default application using cordova file opener plugin. Below is my code.
pdfMake.createPdf(YOUR_DEFINITION_HERE).getBlob(buffer => {
this.file.resolveDirectoryUrl(this.file.externalRootDirectory)
.then(dirEntry => {
this.file.getFile(dirEntry, 'test1.pdf', { create: true })
.then(fileEntry => {
fileEntry.createWriter(writer => {
writer.onwrite = () => {
this.fileOpener.open(fileEntry.toURL(), 'application/pdf')
.then(res => { })
.catch(err => {
const alert = this.alertCtrl.create({ message:
err.message, buttons: ['Ok'] });
alert.present();
});
}
writer.write(buffer);
})
})
.catch(err => {
const alert = this.alertCtrl.create({ message: err, buttons: ['Ok'] });
alert.present();
});
})
.catch(err => {
const alert = this.alertCtrl.create({ message: err, buttons: ['Ok']
});
alert.present();
});
});

Does anybody hit this error while updating autoupdate for electron application.
It says:
Error: Can not find Squirrel
enter image description here
below is my code:
const server = 'http://10.172.120.67:8081'
// const url = `${server}/update/${process.platform}/${app.getVersion()}`
const url = `${server}/update/`
console.log(url)
autoUpdater.setFeedURL({ url })
autoUpdater.on('update-downloaded', (event, releaseNotes, releaseName) => {
console.log("getin")
const dialogOpts = {
type: 'info',
buttons: ['Restart', 'Later'],
title: 'Application Update',
message: process.platform === 'win32' ? releaseNotes : releaseName,
detail: 'A new version has been downloaded. Restart the application to apply the updates.'
}
dialog.showMessageBox(dialogOpts).then((returnValue) => {
if (returnValue.response === 0) autoUpdater.quitAndInstall()
})
})
autoUpdater.on('error', message => {
console.error('There was a problem updating the application')
console.error(message)
})
autoUpdater.on('update-avliable', function (info){
console.log('update-avliable')
})
autoUpdater.on('checking-for-update', function () {
console.log('checking-for-update')
});
console.log("hello electron")
autoUpdater.checkForUpdates();
Try calling the check for updates when the app is ready:
app.on('ready', function() {
autoUpdater.checkForUpdates();
}
I dont get the token when i use my iphone. I get the token when i use the simulator.
I use nativescript-firebase-plugin and in main.js i do the firebase.init functions.
I have tried with everything i have found on this error, or i dont even know if its a common error. The full init looks like this
firebase.init({
showNotifications: true,
showNotificationsWhenInForeground: true,
onPushTokenReceivedCallback: (token) => {
console.log(`onPushTokenReceivedCallback: ${token}`);
appSettings.setString('firebasemessagekeytoken', token);
},
onMessageReceivedCallback: (message) => {
console.log(`onPushTokenReceivedCallback: ${message.title}`);
}
})
.then(() => {
console.log('[Firebase] Initialized');
})
.catch(error => {
console.log(`error: ${error}`);
});```
I have developed an app that allows you to open and edit Office files (.docx) in Word. In order for the app and Word to have appropriate permissions on iOS, I set the option "LSSupportsOpeningDocumentsInPlace" to YES in my info.plist file.
What I also want is that I can share files directly from the Files app into my app. However, with iOS the option "Share to 'myApp'" does not work anymore as soon as I set "LSSupportsOpeningDocumentsInPlace" to YES but only "Open in 'myApp'". And that's exactly where the problem lies when I pass the passed file path to Plugin File.
Without "LSSupportsOpeningDocumentsInPlace" I get the following path:
file: ///private/var/mobile/Containers/Data/Application/300F9E3A-2E17-4330-8F88-12855269CCA8/tmp/com.my.app-Inbox/Dokument.docx
The plugin file recognizes the path and I can do anything else with the file I want.
But with set option "LSSupportsOpeningDocumentsInPlace" to YES I get the following path:
file: ///private/var/mobile/Containers/Data/Application/304CFCDB-227B-4149-9F87-078B341F7A00/Documents/Dokument.docx
And the plugin file returns the error: "NOT_FOUND_ERROR"
Is there a way that works both? The parts function from FILES and the permission to edit documents out of the app?
EDIT:
import {File} from '#ionic-native/file'
...
constructor(public file: File) {
}
this.deeplinks.routeWithNavController(this.nav, {}).subscribe(
(match) => {
this.storeFile(match.$link.url);
}
}, (nomatch) => {
});
storeFile(filepath) {
this.file.resolveLocalFilesystemUrl(filepath)
.then((entry) => {
console.log(entry);
})
.catch((e) => {
console.log(e)
})
}
EDIT 2:
storeFile(filepath) {
this.file.resolveDirectoryUrl(path1)
.then((entry) => {
console.log('+++++++++++++++', entry);
this.file.checkDir(entry.nativeURL, '')
.then((dir) => {
console.log('+++++++++++++++ dir', dir);
this.file.listDir(entry.nativeURL, '')
.then((list) => {
console.log('+++++++++++++++ list', list);
})
.catch((e) => {
console.log('--------------- list', e) // <--- NOT_FOUND_ERROR
})
})
.catch((e) => {
console.log('--------------- dir', e)
})
}, (e) => {
console.log('---------------', e)
});

I'm currently trying to implement some functionality in my react native app where I use information stored locally if the device is offline, and perform a fetch if the device is online.
I used NetInfo after reading this How to handle network failure in React-Native, when network is off, but unfortunately I ran into an error where NetInfo always returns offline. I found this github issue, which recommended that I change the host in RCTReachability.m from 'htpp://apple.com' to 'apple.com'. However, I couldn't find a file with that name in the project directory. Instead I found the only mention of 'apple.com' in any file, which was in RCTNetInfo.m, which was in the correct form.
Does anybody know a way to fix this problem? Or possibly a different way to go about performing one action if the device is online, and another if the device is offline?
Here's the relevant code:
fetchData() {
NetInfo.isConnected.fetch().done((isConnected) => {
console.log('First, is ' + (isConnected ? 'online' : 'offline'));
if ( isConnected )
{
fetch(REQUEST_URL)
.then((response) => response.json())
.then((responseData) => {
store.save('contacts', responseData.feed.entry)
.then(() => store.get('contacts'))
.then((contacts) => {
this.setState({
dataSource: this.state.dataSource.cloneWithRows(contacts),
isLoading: false
});
})
})
.catch((error) => { console.error(error); });
}
else
{
store.get('contacts')
.then(contacts => {
if (contacts == null)
{
this.setState({
dataSource: this.state.dataSource.cloneWithRows(CONTACT_DATA),
isLoading: false
});
}
else
{
this.setState({
dataSource: this.state.dataSource.cloneWithRows(contacts),
isLoading: false
});
}
})
}
});
}
On the simulator it does not crash and Alerts the error, but in production it is crashes as soon as fetch request suppose to be made and it is impossible to reopen the app until network connection is back (I turn on/off airplane mode for the testing)
here are the snippets of my code
componentWillMount: function(){
NetInfo.isConnected.addEventListener('change',this.handleConnectivityChange)
NetInfo.isConnected.fetch().done((data) => {
this.setState({
isConnected: data
})
console.log('this.state.isConnected: ', this.state.isConnected);
})
},
handleConnectivityChange: function(){
var connected = this.state.isConnected ? false : true
this.setState({isConnected: connected})
console.log('this.state.isConnected11: ', this.state.isConnected);
},
....
goToList: function(replace, listview){
console.log('this.state.isConnected: ', this.props.isConnected);
if (!this.props.isConnected){
AlertIOS.alert('Error', 'Please check your network connectivity')
this.props.removeFetching()
return
}
....
fetch(url)
.then((response) => response.json())
.then((responseData) => {
....
.catch((error) => {
StatusBarIOS.setNetworkActivityIndicatorVisible(false)
AlertIOS.alert('Error', 'Please check your network connectivity')
this.props.removeFetching()
})
.done()
I spent a lot of time trying to find a way to catch exceptions when using fetch() but I was unable to get it working (e.g. using .catch() or a try/catch blog didn't work). What did work was to use XMLHttpRequest with a try/catch blog instead of fetch(). Here's an example I based off of: https://facebook.github.io/react-native/docs/network.html#using-other-networking-libraries
var request = new XMLHttpRequest();
request.onreadystatechange = (e) => {
if (request.readyState !== 4) {
return;
}
if (request.status === 200) {
console.log('success', request.responseText);
var responseJson = JSON.parse(request.responseText);
// *use responseJson here*
} else {
console.warn('error');
}
};
try {
request.open('GET', 'https://www.example.org/api/something');
request.send();
} catch (error) {
console.error(error);
}
