Added manifest

android:name=".ProductDescriptionActivity"
android:exported="true"
android:screenOrientation="portrait"
android:theme="#style/Theme.AppCompat.NoActionBar">
<intent-filter>
<action android:name="com.abc.allaboutcity.MESSAGE" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="http"
android:host="http://allaboutcity.in"
android:pathPrefix="/allaboutcity" />
</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 "example://gizmos” -->
<data android:scheme="allaboutcity"
android:host="allaboutcity" />
</intent-filter>
</activity>

You should add intent filter in your manifest file to activity that you want to open
<activity
android:name="Your Activity"
android:label="Your Activity Title"
android:theme="Your Style">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data
android:host="your url"
android:path="/your path"
android:scheme="http" />
</intent-filter>
</activity>

use this code In Your WebView Activity
Intent intent = getIntent();
String action = intent.getAction();
Uri data = intent.getData();
Webview webView = (WebView) findViewById(R.id.webview_id);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl(""+ data);
next, use this code in AndroidManifest.xml, its for all link (Https / Http):
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="https"/>
<data android:scheme="http"
android:host="http://allaboutcity.in"
android:pathPrefix="/allaboutcity" />
<data android:host="www.host.com" android:pathPattern="/movie/0.*/" android:scheme="http"/>
</intent-filter>

Android. Deep linking doesn't work with http/https scheme

I added a deep linking to my Android app this way:
<activity
android:name=".views.DeepLinkingActivity"
android:exported="true">
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data
android:scheme="https"
android:host="example.com"/>
</intent-filter>
</activity>
When I click on https://example.com I get redirected to the web site.
When I change android:scheme="https" to android:scheme="appscheme" it works and it redirects me to my app.
How to force my app to be opened via https scheme?
UPDATE
I added a subdomain and it still doesn't work.
<activity
android:name=".views.DeepLinkActivity"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data
android:scheme="https"
android:host="www.example.ru"/>
</intent-filter>
</activity>

Thanks to veritas1 I removed android:autoVerify="true" from https-scheme. I also changed the scheme from https to http. (You can read about autoVerify).
So, currently have two different schemes:
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data
android:host="your-site.com"
android:pathPrefix="/"
android:scheme="http"
/>
</intent-filter>
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data
android:host="your-site.com"
android:pathPrefix="/"
android:scheme="myapp"
/>
</intent-filter>
When clicking on a link myapp://your-site.com/... an application will be opened. When clicking on http://your-site.com/... Chrome browser will offer to open in the application or another browser, while other mobile browsers ignore this and try to open themselves.
UPDATE
See https://stackoverflow.com/a/60342565/2914140 for App Linking.

Hi please use the following data and try also refer this doc
<intent-filter>
<data
android:scheme="ou unique scheme(appname,package name)" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.BROWSABLE" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
OR
<data
android:scheme="you unique scheme(appname,package name)"
android:host="www.example.ru"/>

You refer to deep linking but android:autoVerify="true" is used for App linking, so the domain example.com (which you don't own?) is going to get checked for a digital asset links json file. See https://developer.android.com/training/app-links/index.html
For your test to work I'd suggest removing android:autoVerify="true" and adding a subdomain to the host e.g. android:host="www.example.com"

Try this
<activity
android:name=".views.DeepLinkingActivity"
android:exported="true">
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data
android:host="open"
android:scheme="example" />
</intent-filter>
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data
android:host="example.com"
android:pathPrefix="/"
android:scheme="http" />
</intent-filter>
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data
android:host="example.com"
android:pathPrefix="/"
android:scheme="https" />
</intent-filter>
</activity>

Please check below it may be help

Just use http. Don't know when the implementation is changed.
But I just tested that using http will make both http and https work.
So change you intent filter by:
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data
android:scheme="http"
android:host="example.com"/>
</intent-filter>

youe can also add to it
sub.example.com
<intent-filter android:label="#string/app_name">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="http" android:host="example.com" />
<data android:scheme="app" android:host="com.example.example" />
</intent-filter>

Deep Linking not working

activity
android:name=".activity.rechargetab.RechargeActivity">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="mobileleb"
android:host="recharge/checkout/status" />
</intent-filter>
</activity>
When I try mobileleb://recharge/checkout/status from the browser it searches google.Its not working. It does not start RechargeActivity.

add android:autoVerify="true" to intent-filter and specify scheme="http" or "https" or both
<activity
android:name=".activity.rechargetab.RechargeActivity">
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="http" android:host="mobileleb" />
<data android:pathPattern ="/recharge/checkout/status" />
</intent-filter>
</activity>

Control multiple activity intents in android

I am trying to open my app depending on the url that is entered but in some cases it tries to execute several activities at the same time, is there any way to restrict this so that the MainAction does not execute when trying to execute another?, basically my manifest goes like this
Main Activity
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="http" />
<data android:scheme="https" />
<data android:host="www.test.com" />
<data android:host="m.test.com" />
</intent-filter>
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data
android:host="home"
android:scheme="testapp" />
</intent-filter>
</activity>
Detail Activity
<activity
android:name=".DetailActivity"
android:label="#string/title_activity_detail"
android:launchMode="singleInstance"
android:theme="#style/AppTheme.NoActionBar">
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data
android:host="detail"
android:scheme="testapp" />
</intent-filter>
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="http" />
<data android:scheme="https" />
<data android:host="www.test.com" />
<data android:host="m.test.com" />
<data android:pathPrefix="/homes"/>
</intent-filter>
</activity>
the problem is that when i try to open a link like "http://www.test.com/homes" this happens:

Your DetailActivity should be declared as shown below, no intent filter is needed.
<activity
android:name=".DetailActivity"
android:label="#string/title_activity_detail"
android:theme="#style/AppTheme.NoActionBar">
</activity>

The thing that matters is the launchMode for the MainActivity
You should read that : https://developer.android.com/guide/topics/manifest/activity-element.html#lmode

How to register app to share all types of files?

I am trying to use intent filters to do this. I tried this Intent filter for files only but it didn't work. I want to make my app appear in the share menu for all types of files.
Here my intent filter
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="text/plain" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="image/*" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="content" />
<data android:mimeType="*/*" />
<data android:host="*" />
</intent-filter>

Try this. It's working in my project
<intent-filter>
<!---->
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="*/*" />
</intent-filter>
