Android - Deeplink not working with custom url scheme

I'm dealing with two problems here. This is my manifest:
<category android:name="android.intent.category.LAUNCHER" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:host="www.example.com" android:pathPrefix="/test/" android:scheme="https" />
<data android:scheme="myapp" />
First of , I't redirect to my application when I type inside Chrome's
URL. If I click on a link "https:www.example.com/test/kakaka" inside
an SMS, it shows if I want to open my application as expected. But,
if I paste this link inside Chrome URL place and go, it does nothing.
Second problem: Okay, so I decided to test with my custom scheme. I
put on Chrome's URL "myapp://open" and it should work, right? But it
doesn't. So, I removed the line <data
android:host="www.example.com"..... and myapp:// WORKS! So, cant I
have more than 1 scheme in one activity?

When you put two <data> elements inside an <intent-filter> they are merged together. If you want two different specific urls, then create a second <intent-filter> with the second url scheme.

app indexing - how not to map all my website to the app

I've been implementing google app indexing in my app, though it's turning out to be very hard for me to understand.
I've created the following intent-filter in my app
<intent-filter android:label="#string/app_name">
<data android:scheme="android-app"
android:host="com.towers.mywebsite" />
<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="www.mywebsite.com" />
<data android:scheme="https"
android:host="www.mywebsite.com" />
</intent-filter>
I'd like to grab all the links like www.mywebsite.com?parameter=123 but NOT links like www.mywebsite.com/somethingelse
With the intent-filter above, my app is in the list of possible apps to open all the deep links like www.mywebsite.com...
My question is: am I doing it right? How am I supposed to filter the intent in order not to make all the links try and open tre app? I thought google would have chosen open-the-app-or-the-browser by checking which pages of my website do have the link rel attribute, but it seems like it only relies on my app intent-filter. Therefore, I need to tweak them in order to filter only the pages I want. How can I do that?
Thank you

You can rely on markups if you don't declare App-Website association.
https://developers.google.com/app-indexing/android/app#declare-a-website-association
You can also try controlling indexing by creating noindex.xml file to specify the URLs you want excluded from the Google index.

How to block URL to open my android app?

My android app allows to open other website like "http://www.google.com" in a web browser from app. And my code is below.
<activity
android:name=".HomeActivity"
android:launchMode="singleTop"
android:screenOrientation="portrait" >
<intent-filter>
<category android:name="android.intent.category.DEFAULT" />
<action android:name="android.intent.action.VIEW" />
<data android:scheme="http" />
<data android:scheme="https" />
</intent-filter>
</activity>
But this gives me a problem. In the email or text message, click any website link, there will be a choice to open from my app. See the picture I posted. If I click on www.google.com in the text message, I will get a choice to open from my app.
I don't want the popup shows my app. How to handle this? Please help. Thanks a lot.

You can't avoid that, unless you specifically know what browser the user wants to use. And you don't know that.
You could have a WebView activity/fragment bundled in your application that will display webpages for you. That way you'd have full control. Here's a guide on WebView

Your app is being displayed in the Complete Action Using chooser because of your intent-filter:
<intent-filter>
<category android:name="android.intent.category.DEFAULT" />
<action android:name="android.intent.action.VIEW" />
<data android:scheme="http" />
<data android:scheme="https" />
</intent-filter>
and particularly because you've specified just a "scheme" entry, with no specific "host". This would in effect offer any web URL intent to open in your app.
Without understanding what your intended behavior exactly is, you can delete the <data> nodes from your intent-filter to remove your app from the Chooser.
Or alternatively, you might want specific URL's to offer your app in the Chooser, like http://yourserver.com and https://yourserver.com, for this you could alter your intent-filter as follows:
<data android:scheme="http" android:host="yourserver.com" />

If your question is to block URLs of other websites in your android app for download purpose then search for the iConstants.java file in your project and write the following code:
public interface iConstants {
public static final String[] DISABLE_DOWNLOADING = {"URL", };
public static final String WEB_DISABLE = "We cannot allow to download videos form this website.";
}

How do I get a domain link to open my app on android?

The following works fine:
I click on the link www.mycompany.com in an email and it starts my app:
<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="www.mycompany.com/download" android:scheme="http"/>
</intent-filter>
However, what I want to work is as below but it's not working:
I want to be able to restrict it to the link www.mycompany.com/download:
<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="www.mycompany.com/download" android:scheme="http" />
</intent-filter>
Why the distinction? I don't want to block my entire website with the app. I just want that specific domain to redirect to the app. How do I do that?

What you've shown is not a subdomain. That is,
www.mycompany.com/download
is not a subdomain of
www.mycompany.com
But you could use a subdomain to address this issue by setting up something like
download.mycompany.com
and have it map to www.mycompany.com/download. (Most servers allow you to set up subdomains like that.) You can then modify the intent filter accordingly.
EDIT
To support what you're trying to do without setting up a subdomain, you can do the following:
<data
android:host="www.mycompany.com"
android:scheme="http"
android:pathPrefix="download"
/>

I would suggest you to try latest feature made available by Google and that is App-indexing to show your app even when user search about your website on Google.
You need to go through 2 steps:
1 Sign Up for this feature here
2 Update your app as well as sitemap of your website as mentioned here
For further reference you can go through this documentation

Android: using intent filter to launch app doesn't work

I know this question is asked and answered many times on SO, but I just couldn't get it to work. Here is my manifest file (I have 3 activities, I'm showing the only one that I want to be displayed when associated):
<activity
android:name=".MyActivity"
android:label="#string/app_name"
android:theme="#style/HoloDarkTheme" >
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<action android:name="android.intent.action.ACTION_SEND" />
<action android:name="android.intent.action.EXTRA_TEXT" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.action.BROWSABLE" />
<category android:name="android.intent.action.DEFAULT" />
<data android:scheme="http" />
<data android:host="example.com" />
</intent-filter>
</activity>
When I launch a browser and go to "example.com", my app isn't launched. Is there something wrong with the above XML?
Not sure if relevant, but this activity uses MediaPlayer to play videos. Also, I'm using SDK version 11.

I figured it out. It's simply a case of typo. Instead of this,
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.action.BROWSABLE" />
<category android:name="android.intent.action.DEFAULT" />
I needed to replace "android.intent.action" with "android.intent.category" in the last two lines:
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.BROWSABLE" />
<category android:name="android.intent.category.DEFAULT" />

I'm adding this answer here because this thread is one of the top hits when googling "intent filter to launch app from http not working". I suppose the root cause for me could also be considered a typo, but I'm going to call it an "Android documentation defect".
There's a line way toward the bottom of this page that breaks down a URI as:
<scheme>://<host>:<port>/<path>
This breakdown indicates that the "://", ":" and "/" will be added for me so I used the following data in my intent-filter:
<data android:scheme="http" />
<data android:host="my.school.edu" />
<data android:path="thingy" />
I then sent myself an SMS with the following text: "my.school.edu/thingy", which was recognized by my SMS client (Hangouts) as a web address, so it made it clickable. However, clicking on it just gave me a choice of browsers, my app was a no-show.
So I removed the host and the path, and my app launched for any link (or at least every one I tried). I put the host back in and it still worked. Put the path back and we're back to not working. On a whim I decided to prepend a slash to the path:
<data android:path="/thingy" />
...et voilà! There's my app in amongst the browsers! So the error in my view is Android's doc that suggests that the slash is inserted automagically. :) It apparently is not.
More Info: I'm using the HTTP scheme because that's what gets made clickable in SMS and email messages, giving me a free ride to that point.
And note that if you specify a unique host (and path), and the user selects "Always" when choosing your app from the list, future taps on your link will bypass that choice dialog and go straight to your app, which is nice.

Make sure you have the internet permission in your manifest.

I doubt that you can override the http scheme to point back to your app.
