To start Android Applications from website - html

I am a c# programmer that loves android phones knowing that I am never going to learn Java.
What I want to to is an ordinary website that starts the relevant applications from my android phone (Legend) with parameters like:
This works:
Mail - this opens the email klient with correct to=john#doe.com
href="tel:+4512345678" opens the phone with the correct digits on the screen
href="geo:something" opens google map and show you your location
This does not work:
href="sms:+4512345678, body=Hello You"
href="geo:+address" - I want to enten an adress I can navigate to...
Is the last ones possible do do or something like it?
Can you send me link or description
Help would be very appreciated
Thanks in advance

Never say never. Java is pretty close to c#.

Whatsapp Click-to-Chat "Couldn't open link" Error Chrome Android/iPhone

I'm using Whatsapp Click-to-chat functionality, without a phone number. It previously worked but with the new Chrome version 76.0.3809.132, both on iOS and Android is not working anymore. On Android, it's showing a Toast with Couldn't open link. Tried contacting Whatsapp Support but no answer as of yet. With the latest update their own documentation example is not working, link to docs. Any suggestions or experiences?
Link example:
<a target="_blank" href="https://wa.me/?text=Villa%20stone%20road%20piece%2015%20meters%20from%20the%20asphalt%20street" title="Share on WhatsApp">
Error picture Imgur: picture
A table with my tested devices and versions on Imgur
If you use https://api.whatsapp.com/send instead of https://wa.me/ you don't need to specify a phone number.
e.g
https://api.whatsapp.com/send?text=Your%20Custom%20Text
It seems that chrome does not accept click to chat without a number specified. Once there's a number in the URL it works just fine.
Unfortunately I did not find a hack to get around it. Neither of this worked:
https://wa.me//?text=Hello%20World
https://wa.me/0/?text=Hello%20World
only if a proper number is specified it will open WhatsApp, but has the recipient already pre selected (the number we provide).
I tested it for a client about 2 weeks ago, when it still worked. So the last update of Chrome (from Aug 26) seems to be the problem...
The best is to use the custom url scheme format. Universal links do not work well with native clients
whatsapp://send/?phone=&text&source&data
It will work without phone number also.
My issue on a recent breaking-change: Universal links stopped working
There was a great blog post about the issue, however it is already outdated and proposes a php specific solution (nevertheless might gives you a good idea, how to think about the problem)
const text = "Hello..."
const phoneNumber = "23400000000000"
Linking.openURL(`whatsapp://send?text=${text}&phone=${phoneNumber}`)
First: Official Whatsapp Sharing Documentation. One of the following URLs is recommended for WEB use...
https://api.whatsapp.com/send?text=YourShareTextHere
https://api.whatsapp.com/send?text=YourShareTextHere&phone=123
And these for MOBILE use...
whatsapp://send?text=YourShareTextHere
whatsapp://send?text=YourShareTextHere&phone=123

Share contact, html-input type

It is possible to share contact from my phone to html form (upload file), just like popular phone apps like whatsapp and etc do?
I really like how we upload images from phone, when we use <input accpet="images/*" type="file"> - it opens phone's gallery once I hit the input[type="file"].
I wonder if there is a same feature exists that opens contacts book.
I know that there are contact-files with VCF format (https://en.wikipedia.org/wiki/VCard). But can figure out if it is possible to use the format in accept field of input.
My guess is that you should use one of the next mime-types to provide users ability to upload VCards:
text/x-vcard
application/vcard (Macintosh only)
text/anytext
text/directory
application/x-versit (Eudora Plug-in)
text/x-versit (Eudora Plug-in)
text/x-vcalendar
Source.
Regarding direct access to contacts from mobile, this feature has a proposal status. Repo is https://github.com/WICG/contact-api. You can play with the feature here https://whatwebcando.today/contacts.html.
Hope these help!

Link to chat whatsapp desktop

Is it possible to create link to chat for whatsapp on desktop and specify number
which doesn't exist in contact list?
whatsapp
This implementation works fine for mobile(doesn't matter number exists in your contact list or not), but for desktop in doesn't work if there are no such contact in your contact list and as a result I got a pop-up window with message 'Phone number shared via url is invalid'
yes, this is possible, but you need to :
Specify the text or/and link
For opening contact list, on zap, just set the content as text .
whatsapp://send?text=http://www.yoursite.com
Specify the zapzap telenumber for sending directly to contact .
whatsapp://send?phone=5531920095096&text=http://www.yoursite.com
You can also use the zapzap oficial page. This takes 2 steps :
https://api.whatsapp.com/send?phone=5531920095096&text=Hello
Remember that, all content on text variable must be a encoded string, and also that phone number have no spaces, or characters, also country code have not +
This is a nice feature, works very well. You can use (3) option and create a "goo.gl" url, and for options (1) and (2) you can trigger on a website, or app .
Actually, i'm trying to find some way to make whatsapp:// open in whatsapp desktop instead of asking for choose app from microsoft appstore, because now, its not opening it anymore, i dont know why, this used to work .
By the way, if you are a spammer .. don't even try anything, or we will catch you and all your fake numbers or profiles .
This is not for spamming. You have to use broadcast lists .
You can send the phone number so i can check if its correct, or, if you like, i can show you how this can be used, in our classifieds, included one buton for contact each seller, so users have an omnichannel experience .
Contacting advertisers from our site very fast, instead of saving, refreshing and contacting, can click and open zapzap chat .
If you have a website a customer service phone line, and a zapzap number, you are already a multi-channel business, so this is for seamless cross channel, so users can change from site to zapzap .
Remember that, best soluction for this issue is to use the API Page (3), and that you need to specify text variable all times, because IF you are going to send, you need to send something, and also, there is a "=" character after the phone number variable (at your example) that must be removed .
Please vote this up, because it took a long time to do .
Comment if you have anything to add .
Remember also that this is 2017-2018, and the zap implementation had started some months ago. Please whatsapp, let us opening whatsapp:// protocol from chrome to whatsapp desktop, it was working so nice .. please, it save us so much time, to start a conversation with a number not on contact list, and its working on mobile, just on desktop, that was nice, but since December update, its not running,.. whatsapp pleeeeeeeeeaseeeeee .
UPDATE: As i changed my phone number, i updated the post, because many people arround world contact me saying "thank you" or asking help on something .
Try this:
<body class="" onload="myWhatsappFunction()">
<a id="whatsapp-btn" class="" target="_blank"> Whatsapp</a>
<script src="https://cdnjs.cloudflare.com/ajax/libs/mobile-detect/1.4.3/mobile-detect.min.js"></script>
<script>
var whatsapp_number = YOUR_PHONE_NUMBER_HERE;
function myWhatsappFunction() {
var md = new MobileDetect(window.navigator.userAgent);
if (md.mobile()) {
// mobile link
document.getElementById("whatsapp-btn").href = "https://wa.me/" + whatsapp_number;
} else {
// desktop link
document.getElementById("whatsapp-btn").href = "https://web.whatsapp.com/send?phone=" + whatsapp_number;
}
};
</script>

To create your own link to your whatsapp number with a pre-filled message that will automatically appear in the text field of a Whatsapp WEB-chat, you can use: (Dont work on Firefox web browser)
<a href="https://api.whatsapp.com/send?phone=yourwhatsappnumberwithcountrycode&text=hello"</a>
this API promises work on all browsers check it out:
https://www.forblink.com/
Try to use such link - https://wa.me/"number" where the "number" is a phone number in international format without + or - or dots.
So it must look like that: https://wa.me/89273546633
A possible cause of this error 'Phone number shared via URL is invalid' is that the phone number that you are trying to invoke is not on Whatsapp list, i.e. the number does not receive WhatsApp messages since it might not be registered on WhatsApp. I tried that using several of my phone numbers and the ones not on WhatsApp were throwing this error but those on WhatsApp worked. Guess will save someone from debugging.
I had the same problem in the past week, only links like wa.me/number were working fine on desktop for the past few years.
It seems that WhatsApp’s policy changed. I read advice about updating or accepting the privacy policy "which I don't" but all not correct. I tried different account on new installation and it didn't work.
It does not require the phone to be in your contact list, if you chatted with the number it will work. If there is no previous chat it stopped working a week ago.
A very simple solution. I added my country's area code (+44) in-front of the mobile number.
It works for both mobile and desktop.
Alternate solution
If you have specific numbers to send
You cane upload the numbers on Google contact
Same email I'd needs to be in mobile

Dynamic Link Actions in mailchimp

I need to do dynamic link opening based on each of 3 cases. How do I write this into a link ?
Case 1: user is on desktop or Android. Send user to website link with
reference to content example.com/content/123
Case 2: user is on
iOS app is not installed. Send to App Download, post download open
content article that user tapped on
Case 3: user is on iOS app is
installed. Open app with activity link and link to that activity in
the app myapp://content/123
Any ideas how to write this into an HTML source that I can add to email? On click it will have to figure out what it wants to do.
Here is what the source looks like in mailchimp email template per content item:
<span>A brief funny description about this place, in one or two phrases...

</span>
Any help is greatly appreciated.
You are looking for the concept of deep linking. I can help you with 2 of your cases
First I'll explain how I would attempt to make this work. This sample will open the Facebook app and navigate to the Wikipedia page. You can try this out by opening this link from your Android or iOS device.
Instead of having the direct link in the email itself, I'd use one link that would then, on the server's side, determine the action to take.
In your email template, do this
<span>A brief funny description about this place, in one or two phrases...
Read More
</span>
This should then take the user to a script named 'my_server_script.php' (my example is PHP, but you can achieve this in any language).
In this script, you can then check the User Agent by using PHP's $_SERVER['HTTP_USER_AGENT']. This will give you something like Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en) AppleWebKit/418 (KHTML, like Gecko) Safari/417.9.3. Then by parsing this string, you can determine the user's OS and take an action based on that. Please do note that User Agent strings can be modified and is not always 100%, but it should be more than enough for your use.
Once you have determined the action to take, you could redirect the user to the app by sending them to the deeplink.
Here is PHP code I tested on Android earlier, this should open the Facebook app and take you to the Wikipedia page. As far as I know, it should work on iOS as well.
<?php
// Set App deeplink
$app_url = 'fb://profile/33138223345';
// Try to redirect the device to the URL
header('Location: ' . $app_url);
?>
I don't have a solution for detecting if the app is installed, but if you do find a solution for
that, you should be able to redirect them to the appropriate app store using the code below
<?php
// iTunes link
$app_install_link = 'https://itunes.apple.com/za/app/facebook/id284882215?mt=8';
// Then redirect the user to the app store location
header('Location: ' . $app_install_link);
?>
If you determine they should be sent to the desktop version, simply do
<?php
// Browser link
$link = 'https://example.com/content/123';
header('Location: ' . $link );
?>
This is personally how I would make this work since you won't have the capability in the email itself to check what device you are on and modify the link based on that.
You should however still be able to use the deeplink fb://profile/33138223345 by doing
<span>A brief funny description about this place, in one or two phrases...
Read More
</span>
and that should open the Facebook app on iOS and Android.
Hope this helped a bit!

How to use HTML to do a Skype call?

I tried to insert the following snippet in my script. By clicking the link it should do a call to a Skype account. I've been looking for hours now, but can't figure out why it doesn't work.
<pre><code><a href="callTo://USERNAME"><img src="http://goodies.skype.com/graphics/skypeme_btn_small_green.gif" border=0></a></code></pre>
Is it accepted in any way or do I miss something here?
Try "callto" (with no uppercase letters).
Link will initiate Skype to call my number!
<a href="skype:********?call">Link will initiate Skype
to call my Skype username!</a>
source: http://geek.michaelgrace.org/2010/03/create-html-link-that-starts-a-skype-call/
I have been fighting with the following link all day.
Start chat
The problem that I had was with the USERNAME part
Finally, I just solved it.
My name on Skype web page was name but the real name was name lastname. The link in my web page did make Skype to load in my Android phone but, Skype failed to find the account to wich I wanted to call (name lastname).
I tryed, and failed:
<a href="skype:name lastname?call">...
<a href="skype:name+lastname?call">...
<a href="skype:name%20lastname?call">...
<a href="skype:name-lastname?call">...
<a href="skype:name_lastname?call">...
<a href="skype:phonenumber?call">...
Then, the solution:
<a href="skype:live:emailnamewithoutdomain?call">...
I just hope u find it usefull.
And, do not forget that u have a plenty of commands to add after the ? in the url (add,call,chat,and so on).
Just for another option from their official website:
https://www.skype.com/en/developer/create-contactme-buttons
It's nice and easy to use, can be used both for chat or/and call.
