WebView is unable to trigger URLScheme?

B4X: 
Sub FinishDownload
    Log(">>> FinishDownload")
    'Activity.RemoveAllViews
    'Activity.LoadLayout("2")  
    WebView1.LoadHtml("<html><script>function SMS(){window.location.href='sms:0012127773456';}</script><body onload=SMS(); > or click <a href='sms:0012127773456'>SMS</a></body></html>")
    'WebViewExtras1.addWebChromeClient(WebView1, "")
End Sub

Seems that there is no app installed on your device which has registered the scheme sms://
I´m wondering why you want to send a sms from a webview if you already have ALL YOU NEED in the Phone lib of b4a...

B4X: 
Dim Sms1 As PhoneSms
Sms1.Send(phone number,"hello")

Let me clear the confusion.

1. i have primary Java app with third party SDK's (to do audio/video/presentation/logmein etc etc)
2. I need secondary app to trigger URLScheme to my primary APP. (not only SMS service to use)

If i am not wrong. In past it worked with Cordova even. Not sure how to do it in B4A.

You are free to define a new scheme (and your app responsible for this scheme)... Like myscheme://blabla
Any link with the scheme myscheme:// will be starting your app. You app need to read the parameters and parse them...

B4X: 
AddActivityText(Main,
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<!-- Accepts URIs that begin with "beka://service” -->
<data android:scheme="beka" android:host="service" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<!-- Accepts URIs that begin with "beka://kunden” -->
<data android:scheme="beka" android:host="kunden" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<!-- Accepts URIs that begin with "beka://ab” -->
<data android:scheme="beka" android:host="ab" />
</intent-filter>
)

this manifestchange will make the app responsible for the following urls

- beka://kunden/
- beka://service/
- beka://ab/

Link to a sample-project (in the german forum)

PD: Bill; check the sample... This will work using a B4A Webview too

See this examples.

Compile and install serviceapp first. It registers the schemes...
Quit the app
Compile and run wvapp. A wv with a html page from assets is shown. Click on any of the links to open the service app

Its working.

[Exception]: FYI

- when i use your sample (works). But when i use your "wvapp.zip" to trigger mine/third party SDK apps similar way, then it still fail like before
- To execute my/third party (closed source) SDK.
when i use following RAW method (without using WebView, WebViewExtra) it do work too

B4X: 
Sub callPrimaryApp
    Dim Intent1 As Intent
    ' works : "closedsourcesdk://arg0_arg1_arg2/"
    ' works : "closedsourcesdk://arg0_arg1_arg2"
    Intent1.Initialize(Intent1.ACTION_VIEW, "closedsourcesdk://arg0_arg1_arg2")
    StartActivity(Intent1)
End Sub

The problem seems to be in the scheme parts.
Compare it to real URLs to a domain giving some vars.

For example

Register a scheme
"closedsource"
which is responsible for the domain "sdk".

You then can handle all links to "closedsource://sdk/*

For ex:
closedsource://sdk/arg0/arg1/arg

The app reacts on closedsource://sdk
Everything from the Query (in this case /arg0/arg1/arg) you need to parse yourself. BUT you can use as many parameters you want. You just need to be able to parse it in the main app....
