Deeplink does not open the app from Gmail

We are trying to implement deepLink from a Gmail in our app. I add following code to my Manifest file :
<activity
android:name="io.fetchcar.archapp.MainActivity"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter android:label="#string/filter_view_fetch">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="fetch" />
</intent-filter>
</activity>
In the Gmail we have following button with html code :
Fetch A Car Now
But when we click on the button from Gmail, it does not open the app.
The thing is if we open it as a web page in the browser and click on Fetch A Car Now button, it opens our app as expected.
Is it any limitation to open our app with Deeplink from Gmail ?

Browser can't open an app from a browser using deeplink

I'm trying to implement deeplinks in my, so users will be able to open the application from a browser. So, I've added deeplinks in my application in a Manifest.xml. And this code is working from adb, but when I'm trying to open this link in browser, the application does not opens. What can cause this error? I can even can't see an Intent in my code
<activity
android:name=".ui.main.MainActivity"
android:configChanges="orientation|screenSize|screenLayout|smallestScreenSize"
android:screenOrientation="portrait"
android:windowSoftInputMode="adjustPan">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.LAUNCHER" />
</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"/>

Android intent filter not working to launch activity from browser

I've read a tutorial on how to launch an app from a link on the browser. I've created an activity 'TestLaunch'.
<activity
android:name=".TestMe"
android:label="Test">
<intent-filter>
<data android:scheme="testme.com" />
<action android:name="android.intent.action.VIEW" />
</intent-filter>
</activity>
Then I connected my android phone and clicked 'debug' on Eclipse. The app launched as usual. I openned the browser and typed 'testme.com'. The activity was not started as expected. Is this because the app is not fully installed on the phone or because I am understanding wrongly how the intent filter works?

try this:
<activity
android:name=".TestMe"
android:label="Test">
<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:host="www.testme.com" android:scheme="http"></data>
</intent-filter>
</activity>

Launch Android application from browser

I have a little problem.
I have an Android Activity, and I want to run it from one link on the browser.
This is what how I have declared my Activity on the Manifest file:
<activity android:name=".Wul4"
android:windowSoftInputMode="adjustPan"
android:configChanges="keyboardHidden|orientation"
android:launchMode="singleInstance"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="wul4" android:host="com.wul4.wul4"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</activity>
On the webApp, the link to launch the application is the following one:
wul4://com.wul4.wul4?codOperacion="+respuestaActual.idOperacion
The point is that It is working from the following browsers: "Opera" and "Google Chrome", but it is not working for the rest..........(for instance, it is not working on the default browser of the phone).
Anyone knows why???
Thanks a lot!

Try this one, using HTTP instead of your own schema:
<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="com.wul4.wul4"
android:scheme="http:" />
</intent-filter>
When a link with this domain is clicked in an Android device, the user is presented with a dialog to choose between your App (if installed) or the Browser.

Could not launch application by calling a URL from Android Browser

There are many answers in stackoverflow showing how to lauch app from a web browser ,but I am not sure what went wrong with my code, that never seems to be doing the intended.
I am trying to launch my app by a URL from any other app like web browser,initially
my manifest file looks like this
<activity android:name=".Main">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<data android:scheme="http" android:host="ebay.com" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
</intent-filter>
And When I typed http://ebay.com in the browser that never started my app.Obviously,how does the browser know about my app?,then i tried the other way around and added another Activity called MyActivity and altered the manifest file as
<activity android:name=".Main">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".MyActivity">
<intent-filter>
<data android:scheme="http" android:host="ebay.com" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
</intent-filter>
</activity>
and tried in my Main Activity
startActivity(new Intent(Intent.ACTION_VIEW,Uri.parse("http://mycityway.com")));
Thus producing the intended result.I can also start another application Activity using this method.
But most of the answers here says that the later is possible.What is the mistake i am doing,I couldn't launch my app from browser.Please guide me.

And When I typed http://ebay.com in the browser that never started my
app.
It gets started when a matching link is clicked not when you type the url in the browser.
Try it by sending yourself an email containing http://ebay.com and click the link in the email application.
