Using "action" attribute for running apps by Push Messages

Question

When using push messages to start a specific activity within an app,
{pkg: "my.app", action: "my.app.SecondActivity"}
does start the application, but not "SecondActivity".

android:exported is set to true.
What am I missing?

Answer 1

The "action" attribute contains the Action, not the Activity. Your activity should declare in AndroidManifest.xml that it handles a specific Action. See more details here: https://developer.android.com/guide/components/intents-filters

Thank you for your response.

Declaring this in AndroidManifest.xml:
        <activity
            android:name="my.test.project.activity"
            android:exported="true">
            <intent-filter>
                <action android:name="my.test.project.DOACTION" />
            </intent-filter>
        </activity>

And sending a push message of type runApp with this payload:
{"pkg": "my.test.project", "action": "my.test.project.DOACTION"}

It still only starts the App, not the declared action.

Perhaps you need to add a category as suggested here: https://stackoverflow.com/questions/10921451/start-activity-using-custom-action  Also, consider reviewing Headwind MDM launcher code in app/src/main/java/com/hmdm/launcher/worker/PushNotificationProcessor.java#runApplication(), perhaps there's a bug.

Adding
<category android:name="android.intent.category.DEFAULT" />
sadly doesn't fix it.

It must be <category android:name="android.intent.category.LAUNCHER" />
to work.
