I have googled and tried to follow the solutions posted but did not come to a solution.
Does anyone have an idea why
this.contacts.find(["name", "phoneNumbers"],
{multiple: true, hasPhoneNumber: true}).then(
(contacts) =>
{
this.contactList = contacts;
}
).catch(err => {
console.log('contacts error');
console.log(err);
});
is freezing my whole app? While the contacts are grabbed the gui does not respond anymore.
I am using : -
import { Contacts } from '#ionic-native/contacts/ngx';
but I could not solve the problem. I have about 2500 contacts on my iPhone. When using the code on simulator it is fine but simulator only has 6 contacts.
Log says 'Fetching in bulk 250 contacts!' plenty of time.
I'm really stuck and would be very happy if someone could give me a hint to solve this problem.
Best Regards
This plugins requires the following usage description:
NSContactsUsageDescription describes the reason that the app accesses the user's contacts.
To add this entry into the info.plist, you can use the edit-config tag in the config.xml like this:
<edit-config target="NSContactsUsageDescription" file="*-Info.plist" mode="merge">
<string>need contacts access to search friends</string>
</edit-config>
Try to read only the data do you need. In desiredFields you can specify this camps. For example: Obtain only "name" and "phoneNumbers" of all information about each contact.
this.contacts.find(["name", "phoneNumbers"],
{multiple: true, hasPhoneNumber: true}, desiredFields: ['name','phoneNumbers']).then(
(contacts) =>
{
this.contactList = contacts;
}
).catch(err => {
console.log('contacts error');
console.log(err);
});

I want to open whatsapp from my Flutter application and send a specific text string. I'll select who I send it to when I'm in whatsapp.
After making some research I came up with this:
_launchWhatsapp() async {
const url = "https://wa.me/?text=Hey buddy, try this super cool new app!";
if (await canLaunch(url)) {
await launch(url);
} else {
throw 'Could not launch $url';
}
}
Which works ok ish, however there are two problems:
As soon as I make the text string into multi words it fails. So if I change it to:
_launchWhatsapp() async {
const url = "https://wa.me/?text=Hey buddy, try this super cool new app!";
if (await canLaunch(url)) {
await launch(url);
} else {
throw 'Could not launch $url';
}
}
Then the Could not launch $url is thrown.
I have whatsapp already installed on my phone, but it doesn't go directly to the app, instead it gives me a webpage first and the option to open the app.
Here is the webpage that I see:
Any help on resolving either of these issues would be greatly appreciated.
Thanks

P.s. I'm using the Url_launcher package to do this.
From the official Whatsapp FAQ, you can see that using "Universal links are the preferred method of linking to a WhatsApp account".
So in your code, the url string should be:
const url = "https://wa.me/?text=YourTextHere";
If the user has Whatsapp installed in his phone, this link will open it directly. That should solve the problem of opening a webpage first.
For the problem of not being able to send multi-word messages, that's because you need to encode your message as a URL. Thats stated in the documentation aswell:
URL-encodedtext is the URL-encoded pre-filled message.
So, in order to url-encode your message in Dart, you can do it as follows:
const url = "https://wa.me/?text=Your Message here";
var encoded = Uri.encodeFull(url);
As seen in the Dart Language tour.
Please note that in your example-code you have put an extra set of single quotes around the text-message, which you shouldn't.
Edit:
Another option also presented in the Whatsapp FAQ is to directly use the Whatsapp Scheme. If you want to try that, you can use the following url:
const url = "whatsapp://send?text=Hello World!"
Please also note that if you are testing in iOS9 or greater, the Apple Documentation states:
Important
If your app is linked on or after iOS 9.0, you must declare the URL schemes you pass to this method by adding the LSApplicationQueriesSchemes key to your app's Info.plist file. This method always returns false for undeclared schemes, whether or not an appropriate app is installed. To learn more about the key, see LSApplicationQueriesSchemes.
So you need to add the following keys to your info.plist, in case you are using the custom whatsapp scheme:
<key>LSApplicationQueriesSchemes</key>
<array>
<string>whatsapp</string>
</array>

using package: https://pub.dev/packages/url_launcher

TextButton(

Here is new update way...
whatsapp() async{
var contact = "+880123232333";
var androidUrl = "whatsapp://send?phone=$contact&text=Hi, I need some help";
var iosUrl = "https://wa.me/$contact?text=${Uri.parse('Hi, I need some help')}";
try{
if(Platform.isIOS){
await launchUrl(Uri.parse(iosUrl));
}
else{
await launchUrl(Uri.parse(androidUrl));
}
} on Exception{
EasyLoading.showError('WhatsApp is not installed.');
}
}
and call whatsapp function in onpress or ontap function
For using the wa.me domain, make sure to use this format...
https://wa.me/123?text=Your Message here
This will send to the phone number 123. Otherwise, you will get an error message (see? https://wa.me/?text=YourMessageHere ). Or, if you don't want to include the phone number, try this...
https://api.whatsapp.com/send?text=Hello there!
Remember, wa.me requires a phone number, whereas api.whatsapp.com does not. Hope this helps!
I know it is too late for answering this, but for those who want the same functionality, the current way is to do it like this:
launchUrl(Uri.parse('https://wa.me/$countryCode$contactNo?text=Hi'),
mode: LaunchMode.externalApplication);
if you will use URL Launcher then the whatsapp link will be open on web browser. So you need to set parameter - not to open on safari browser. The complete code you can find on this flutter tutorial.
But for your case use below code.
await launch(whatappURL, forceSafariVC: false);
Today i am adding solution its working fine on my desktop and phone

whatsapp://send?phone=9112345678&text=Hello%20World!
I'm working on an ionic mobile application where I needed to read videos on streaming by providing the URI of the video online. So I used cordova-plugin-media-streamingplugin offered by cordova.
My problem is that: the window reading the video closes automatically after the video finishes, the user won't be able to play the video again in this window.
In the official documentation of the plugin [that i found here], there is an attribute called shouldAutoClosethat should be set to false to avoid that problem. But this didn't work for me.
Here is the code I used to play a video on streaming :
startVideo(item : Multimediasendtrust) {
let options = {
successCallback: () => { console.log('Finished Video') },
errorCallback: (e) => { console.log('Error: ', e) },
orientation: 'portrait',
controls: true,
shouldAutoClose: false
};
console.log('those are option ',options );
console.log('the link of the video ', item.url_media);
this.streamingMedia.playVideo(item.url_media, options); }
Can anyone help please. Thanks in advance.
I'm developing ionic 2 app. I'm trying to get high quality image and then resize it to avatar photo.
My code:
_FBUserProfile() {
return new Promise((resolve, reject) => {
Facebook.api('me?fields=id,name,email,first_name,last_name,picture.width(600).height(600).as(picture_small),picture.width(360).height(360).as(picture_large)', [])
.then((profileData) => {
console.log(JSON.stringify(profileData));
return resolve(profileData);
}, (err) => {
console.log(JSON.stringify(err));
return reject(err);
});
});
}
But, the photo isn't good quality, since I guess I did something wrong with the resize in this line:
picture.width(600).height(600).as(picture_small),picture.width(360).height(360).as(picture_large)', [])
How can I get good quality of the photo?
If you want to get the public profile picture of the user and you know the user id from the api call then use this url for picture
profileData.picture="https://graph.facebook.com/"+profileData.id+"/picture?width=1024&height=1024";
You've got a couple of solutions, like using type large
id,name,email,first_name,last_name,picture.type(large)
As explained here: https://developers.facebook.com/docs/graph-api/reference/user/picture/
Can anyone help me find out if/how you can get image data off of the 'camera roll' in an Android device, using (Appcelorator) Titanium ? I have found a 3rd party module for IOS that does this but I am desperate to find one for Android. Otherwise I'll have to scrap the Titanium and go true native.
What I need is a function that returns an array of data about the images on the device. Although I would love to get 'geolocation' data ( if it exists ), all I really need is a 'create date', and a path to the image, or the actual TiBlob.
Seems simple but i get no responses on the Appcelerator forums, which worries me. There must be at least an Android 'module' that achieves this?
Ti.Media.openPhotoGallery({
allowEditing : true,
success : function(event) {
var image = require('/modules/parts/squarecropper').crop(event.media);
setImage(image);
Ti.Media.hideCamera();
},
cancel : function() {
},
saveToPhotoGallery : false,
mediaTypes : [Ti.Media.MEDIA_TYPE_PHOTO],
});
The above method would do your job. Now then either access it directly or get into a file system and encode and decode the data.
var f = Titanium.Filesystem.getFile(currIamge);
var temp = f.read();
var encodeData = Ti.Utils.base64encode(temp);
alert("encodeData = "+encodeData);
Know if it's possible to access the iPhone compass in Safari using JavaScript? I see how the GPS can be accessed, but I can't figure out the compass.
On iOS, you can retrieve the compass value like this.
window.addEventListener('deviceorientation', function(e) {
console.log( e.webkitCompassHeading );
}, false);
For more informations, read the Apple DeviceOrientationEvent documentation.
Hope this helps.
You cannot access that information via javascript, unless you're using something like iPhoneGap
At the time this was true, in iOS 5 you can use the compass heading in JS. https://developer.apple.com/documentation/webkitjs/deviceorientationevent/1804777-webkitcompassheading
For Android it works auto, for iOS it needs to be clicked to start it.
Here's a part of code you can use for that
startBtn.addEventListener("click", startCompass);
function startCompass() {
if (isIOS) {
DeviceOrientationEvent.requestPermission()
.then((response) => {
if (response === "granted") {
window.addEventListener("deviceorientation", handler, true);
} else {
alert("has to be allowed!");
}
})
.catch(() => alert("not supported"));
} else {
window.addEventListener("deviceorientationabsolute", handler, true);
}
}
function handler(e) {
const degree = e.webkitCompassHeading || Math.abs(e.alpha - 360);
}

I advise you to use LeafletJS with this plugin
https://github.com/stefanocudini/leaflet-compass
very simple to use with events and methods.
You can try a demo here:
