Deep-linking intent does not work

Question

I followed the insttructions on https://developer.android.com/training/app-indexing/deep-linking.html, but when I want to trigger the intent through adb with:

Answer 1

Make sure your URL is in this format (with the cap letters replaced by your own):

android-app://COM.YOUR.APP.IDENTIFIER/SCHEME/HOST?somegetparams

The adb tool does not require this format. With the above you can now put it in an src, or an href, like so:

<iframe src="android-app://COM.YOUR.APP.IDENTIFIER/SCHEME/HOST?somegetparams"> </iframe> 
<a href="android-app://COM.YOUR.APP.IDENTIFIER/SCHEME/HOST?somegetparams">LINK</a>

Answer 2

Use this intent filter instead,

<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />

<!-- Accepts URIs that begin with "example://gizmos” -->
<data
   android:host="gizmos"
   android:scheme="example" />
</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" />

<!-- Accepts URIs that begin with "http://www.example.com/gizmos” -->
<data 
    android:host="www.example.com"
    android:pathPrefix="gizmos"
    android:scheme="http" />
</intent-filter>

Answer 3

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.

Answer 4

./adb shell am start -n packagename/.splash.SplashActivity -d "schemeName://content"

Answer 5

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.

Answer 6

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.
