Android Question Open my app with a link

[jvrh_1]

Hello,
I am trying that when my app is shared using a link (for example, a user send a url to another user by whatsapp), If my app is installed in the recpetor user's device, my app open automatically.
I have checked this thread, but doesn't works.

Start App from URI in email

I thought I'd like to share the results of investigations I have carried out today in the hope that some may find it useful. I have an app that stores data as predominantly text and is potentially sharable between a few close groups of people. Rather than create a server and associated comms...

Any idea?

I have checked this thread, but doesn't works.

1. I don´t see any project uploaded which shows the problem!?
2. I don´t see any error log
3. I don´t see which url you are opening on the Device

Any idea?

How could we help with this less information you provide?

DonManfred thank you for anwser. Sorry, but my english is not good and I believe that I have'nt explained well.

There isn't code because I only want, that when I click a link (sending to me by whatsapp, mail...) in my device, my app open or the android system ask to me that What app do I want to use to open this website?

I write this lines in the manifest, but anything happens:

AddActivityText("main",
<intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT"></category>
    <category android:name="android.intent.category.BROWSABLE"></category>
   <data android:scheme="https://" />
</intent-filter> )

 

[DonManfred]

You have
1. Not understand how the entry must be set; you are missing the host part
2. Not implemented it correctly at all; REMOVE :// from the scheme

Are you sure you want to open ALL https links in YOUR app instead of a Browser???

 

[DonManfred]

I believe you need to construct an intent to open the 3rd party app.

You did not understand the problem, @barx

He want to configure is own app to open when someone clicks a specific link in Whatsapp, a website showed in the devices Browser, a email opened in the device email client.

For ex:
barx://myapp/par1

AddActivityText(main,
<intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT"></category>
    <category android:name="android.intent.category.BROWSABLE"></category>
   <data android:scheme="barx" />
   <data android:host="myapp" />
</intent-filter> )

(Untested)

I realised that just after posting, oops. Then quickly deleted the post hoping no-one had seen it yet, oops again. Me creating a big mess again. Sorry

You did not take into account i am in my freetime watching the forum all the day ?

I saw it and i commented it ;-)

 

[jvrh_1]

Yes, I want that when the user clicks on a link (for example www.myapp.com/xxx), the app open automatically and show some mensaje. This messaje depends of the "xxx" part of the link. The link always have the same structure.
Is this possible? I have read some avout schemes, but I don't know how use it and if it could be the solution.
Thank you.

 

[jvrh_1]

I have written this one in the manifest editor. Anything happens.

AddActivityText("main",
<intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT"></category>
    <category android:name="android.intent.category.BROWSABLE"></category>
   <data android:scheme="http" />
   <data android:host="mypackagename" />
   </intent-filter> )

?? I don´t understand

 

[jvrh_1]

?? I don´t understand

When I click over a link that starts with http, open it with the default browser.

I have found it in an other thread. Its yours too. In I think that it could be a solution. But I do not know how modify to my app.

WebView do not allow URLScheme? net::ERR_UNKOWN_URL_SCHEME

WebView is unable to trigger URLScheme? Sub FinishDownload Log(">>> FinishDownload") 'Activity.RemoveAllViews 'Activity.LoadLayout("2") WebView1.LoadHtml("function SMS(){window.location.href='sms:0012127773456';} or click SMS")...

  <!-- Accepts URIs that begin with "beka://ab” -->
  <data android:scheme="beka" android:host="ab" />
</intent-filter>
)

I only want that when I recived a link (in whatsapp for example) that starts with myapp.com, and the user clic over it. My app starts.

changing the theme will not help here. Starting with Whatsapp (and other apps and browsers too) do not know other schemes thena http and https.

To get it working you can use a Domain of yours, add a subdomain for it to be used by your app.

Set the manifest to use this subdomain.

AddActivityText(main,
<intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT"></category>
    <category android:name="android.intent.category.BROWSABLE"></category>
   <data android:scheme="http" />
   <data android:host="muhwies.basic4android.de" />
</intent-filter> )

In this case muhwies is a subdomain of my domain basic4android.de.

I do compile my app and start it at least once to let the Android System know that my app is responsible for any http Link starting with http://moviews.basic4android.de

For example i do send a Message to my Android Device using Whatsapp

and then i open the chat in whatsapp containing this url

i now can click on this url. Android will open my app as it is registered to open all links from the domain muhwies.basic4android.de...
