Deep-linking intent does not work

EDIT:

Ok first make sure that your package is reachable by adb:

adb shell am start -n com.example.simon.test/.activities.MainActivity

Then to accept multiple data tags you need different intent filters (that's the way it worked for me unlike all the other examples I've seen on the net). E.g.:

<intent-filter>
    ...
    <data android:scheme="http"
          android:host="example.com"/>
</intent-filter>
<intent-filter>
    ...
    <data android:scheme="http"
          android:host="example.com"
          android:pathPrefix="/gizmos"/>
</intent-filter>

NOTE that in the above example the pathPrefix starts with a forward slash !

I am not sure why Google's Docs are so misleading or maybe that was for some different version of adb, but the above changes worked perfectly for me. This helped: Source

This is how I made the Chrome browser route specific links to my app:

<activity
    android:name=".activities.DeepLinkActivity"
    android:label="@string/app_name">
    <!-- Accept chrome links -->
    <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="http"
              android:host="example.com"
            android:pathPrefix="/"/>
    </intent-filter>
    <!-- Accept adb data flag -->
    <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="http"
              android:host="example.com"/>
    </intent-filter>
</activity>

NOTE The 1st filter works on Google Chrome while the 2nd one works on the ADB.

NOTE2 The app choice menu won't be shown if the link is entered into the browser's address bar. It has to be a <a href="http://example.com"></a> link in side some page.

In my opinion everything here is rather blurry and really not how I expected it all to work. But that's how it works on my device. Hope this helps (and works) for you too.

After some tests this is what worked for me:

    <activity android:name=".activities.MainActivity">
        <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="www.example.com"
                  android:pathPrefix=""
                />
            <data android:scheme="myschema"
                  android:host="example"
                  android:pathPrefix=""
                />
        </intent-filter>
    </activity>

This works when clicking any link in the browser such as "http://www.example.com", "http://www.example.com/" or "http://www.example.com/whatever". The same with "myschema://example/whatever".

Also works with adb using this command (with any of those URLs):

adb shell am start -W -a android.intent.action.VIEW -d "http://www.example.com" com.example

Hope it helps to get you started.

When everything is working you will probably want to configure a different pathPrefix for different activities.

In my case, I was putting deep linking intent filter in MainActivity which is also main launcher. That caused the problem.

After I created another separate activity and put intent filter there, it solved the problem. Hope this can help others who are facing the same issue.

In my case, I am using an emulator and not an actual usb connected device, and hence I had to change -d to -e, like so :

adb shell am start -W -a android.intent.action.VIEW -e "http://www.example.com" com.example

Note the -e before the deep link.

First, read @user3249477's answer on this page.

I just wanted to add that instead of what he wrote, you can condense it by using pathPattern:

<activity
    android:name=".activities.DeepLinkActivity"
    android:label="@string/app_name">
    <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="http"
              android:host="example.com"
            android:pathPattern=".*"/>
    </intent-filter>
</activity>

The ".*" matches both the empty string and "/", so both cases are covered. If you end up trying to handle multiple scheme's and host's this becomes especially important, so you don't have to spam a powerset of {http, https} X {"", "/"} X {"foo", "bar", etc.}
