I want to Open External Links &
target="blank"
Links in my WebView App in New Close-able Window like GMail App.
I tried to do the same as mentioned here:
Android - Open target _blank links in WebView with external browser
&
Handling External Links in android WebView like Gmail App does
But it is not working.
Please help me implement this feature in my App.
Here's the MainActivity.java file:

Also, I want to open the links of the websites from Google search app and browser directly into the app. As mentioned here:
How to force open URL in WebView? Set App as Default for WebView URL
Which is working fine. Only problem is, all the pages are opening the homepage in app.
Like if an user clicks on a link say https://www.website.com/folder/page from browser, it opens https://www.website.com/ in the app.
How do I fix this issue?
Here's the AndroidManifest.xml file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.blogmaza">
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<!-- Splash screen -->
<activity
android:name=".SplashScreen"
android:label="@string/app_name"
android:screenOrientation="portrait"
android:theme="@android:style/Theme.Black.NoTitleBar" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".MainActivity"
android:windowSoftInputMode="adjustResize|stateHidden"
android:configChanges="orientation|screenSize">
<intent-filter>
<data android:scheme="https" />
<data android:scheme="https" android:host="www.blogmaza.com"/>
<action android:name="android.intent.action.VIEW"/>
<category android:name="android.intent.category.BROWSABLE"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</activity>
</application>
<uses-feature android:name="android.hardware.camera" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
</manifest>
Note: I am fairly new in Android Development. Please post the solution with brief explanation.
from WebView Open External Links & target=blank Links in New Window like GMail App
