Open game using whatsapp/browser link (SOLVED)

Questions
1

I need to open my game and join the client to a game room when the client receives a link via WhatsApp.I used colyseus as a game server.

i hope to send a get request in this format (https://"…serverUR L…":port/api/privateGameRoom?id="…globalroomID ) and use the server to redirect “appname//private_room?id=${data.id}”

Are there any other way to do this process and please kindly advice how I get the parameter values to the game script when app open after calling “appname//private_room?id=${data.id}”

please help me

First of all, you need to register URL scheme in operation system.
On Android, you need to change your AndroidManifest.xml according to this instruction: https://developer.android.com/training/app-links/deep-linking
How to do it on iOS you can read here: https://developer.apple.com/documentation/uikit/core_app/allowing_apps_and_websites_to_link_to_your_content/defining_a_custom_url_scheme_for_your_app

For receiving URL link information use our Inter-app communication module:

Now you have added it as part of facebook activity, but it should be a part of iac activity:

<!-- For IAC Invocations -->
        <activity android:name="com.defold.iac.IACActivity"
            android:theme="@android:style/Theme.Translucent.NoTitleBar"
            android:launchMode="singleTask"
            android:configChanges="keyboardHidden|orientation|screenSize">
            <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="{{android.package}}" />
              <data android:scheme="mygame" host="multiplayer" />
            </intent-filter>
        </activity>

After tests would be better to replace multiplayer and my game with something more unique.

I’m also trying this using defold/extension-iac: Inter-app communication extension for Defold (github.com)

My current issue is when I add this stuff to AndroidManifest.xml, it seems not working

        <!-- For IAC Invocations -->
        <activity android:name="com.defold.iac.IACActivity"
            android:theme="@android:style/Theme.Translucent.NoTitleBar"
            android:launchMode="singleTask"
            android:configChanges="keyboardHidden|orientation|screenSize">
            <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="{{android.package}}" />
                <data android:scheme="kyhoang2" />
            </intent-filter>
        </activity>

but if I add to com.dynamo.android.DefoldActivity like this:

<activity android:name="com.dynamo.android.DefoldActivity"
                android:label="{{project.title}}"
                android:configChanges="fontScale|keyboard|keyboardHidden|locale|mcc|mnc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|touchscreen|uiMode"
                android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
                android:screenOrientation="{{orientation-support}}"
                android:exported="true"
                android:launchMode="singleTask">
            <meta-data android:name="android.app.lib_name"
                    android:value="{{exe-name}}" />
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <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" />
                <data android:scheme="{{android.package}}" />
                <data android:scheme="kyhoang2" />
            </intent-filter>
        </activity>

it seems work, clicking on “kyhoang2://app/test” can open my app but the iac listener not working. What should I do?

I finally figured out why the iac extension not working. Having android:exported="false" is the cause. I had to fork and change it to “true” make it work for me
