Deep-linking intent does not work

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.}

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>

In my case I have a port 8075 in the URL I removed it and it worked

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

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

it will work.

Thanks Simas for your response i would like to add some clarification:

• after testing your activity with this command:

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

• You will need to test your deeplinks ,after adding the intent filter to your AndroidManifest.xml file (lines are below):

  ... ...

so this is the adb command with which you can test :

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

and

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