I am creating a Browser App but Android won't detect my app in chooser while I click on any URL

I am creating a Browser app and I want Android to treat my app as a browser and show up in the app chooser to open with.
I want my app to show up in this list.
Here is my manifest Activity code:
<activity
android:name=".Activity.LinkDetectorActivity"
android:exported="true"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<data android:scheme="testscheme" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.BROWSABLE" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>

Replace your intent-filter with below,
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<data android:scheme="http"/>
<category android:name="android.intent.category.DEFAULT" />
<!-- The BROWSABLE category is required to get links from web
pages. -->
<category android:name="android.intent.category.BROWSABLE" />
</intent-filter>
</activity>

Try to change testcheme to "http" and "https"
<activity
android:name=".Activity.LinkDetectorActivity"
android:exported="true"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<data android:scheme="http" />
<data android:scheme="https" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.BROWSABLE" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>

How to open activity using Voice Interaction?

This is one of my activities in my Android Manifest.
<activity
android:name=".voice.VoiceAccountActivity"
android:label="Qnet Balance"
android:screenOrientation="portrait"
android:theme="#style/AppTheme">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.BROWSABLE" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.VOICE" />
<data
android:host="qnet.balance"
android:scheme="https" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
I've read the Voice Interactions API but every time I say "Open Qnet Balance" it just shows me a bunch of search results from the web. The Browsable and the data qnet.balance I tried to use it as a way to open my app using voice by saying "Open qnet.balance" but that also failed. Anyone have a solution? I'm talking about calling these commands after doing "Ok Google"

Change intent filter tag. And do try to change label to one word it will work.
<activity android:name=".MainActivity" android:label="race">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.BROWSABLE" />
<category android:name="android.intent.category.LAUNCHER" />
<category android:name="android.intent.category.VOICE" />
<data
android:host="qnet.balance"
android:scheme="https" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
It opens only launcher activity. I hope this will work

Open app when user visits url

My problem is that I set my manifest but visiting the website still just loads it in chrome and doesn't open the app. Here's my manifest code for the main activity:
<activity
android:name=".activity.MainActivity"
android:launchMode="singleTop"
android:screenOrientation="portrait">
<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="https" android:host="www.example.com" />
</intent-filter>
</activity>

I'm trying to open my app on a specific page using deeplinking but it keeps opening the start page

<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<data android:scheme="deeplinkingtest"/>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".resetresponse">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<data android:scheme="https"
android:host="callum.pixelpin.co.uk"
android:pathPrefix="/ResetRequest" />
<data android:scheme="http"
android:host="pixelpin.co.uk"
android:pathPrefix="/SignIn/ResetRequest" />
<data android:scheme="deeplinkingtest"
android:host="resetresponse"/>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
I think it may have to do with the scheme, host and pathPrefix not being correct.
The URL in which the app is checking is as follows:
https://login.pixelpin.co.uk/SignIn/ResetResponse.aspx
Full URL:
https://login.pixelpin.co.uk/SignIn/ResetResponse.aspx?code=OAWIBGOAWO893745OBFAIN&user=4389246

Deeplink class set Like below code and must be remove other All scheme .
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="your scheme" />
</intent-filter>
Include the BROWSABLE category. The BROWSABLE category is required in order for the intent filter to be accessible from a web browser. Without it, clicking a link in a browser cannot resolve to your app. The DEFAULT category is optional, but recommended. Without this category, the activity can be started only with an explicit intent, using your app component name.

My Android App is not showing on the App Drawer

I have an application with a single activity:
<activity android:name=".MainActivity"
android:label="#string/app_name"
android:screenOrientation="landscape"
android:launchMode="singleTask"
android:configChanges="mcc|mnc|locale|touchscreen|keyboard|keyboardHidden|navigation|orientation|screenLayout|uiMode|screenSize|smallestScreenSize|fontScale">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<category android:name="com.google.intent.category.CARDBOARD" />
<data android:scheme="myscheme" android:host="action1"/>
<data android:scheme="myscheme" android:host="action2"/>
<data android:scheme="myscheme" android:host="action3"/>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
</intent-filter>
<meta-data android:name="unityplayer.UnityActivity" android:value="true" />
</activity>
I need it to respond to myscheme:// urls, and it is working in that regard. Unfortunately, it does not show in my App Drawer. If I remove the android:scheme lines, then it shows on the App Drawer, but then it no longer responds to myscheme:// urls, obviously.
How can I fix this activity to make it both show on the app drawer and respond to the custom urls?

Try splitting the intent-filter into two:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<category android:name="com.google.intent.category.CARDBOARD" />
<data android:scheme="myscheme" android:host="action1"/>
<data android:scheme="myscheme" android:host="action2"/>
<data android:scheme="myscheme" android:host="action3"/>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
</intent-filter>
