Detailed Description

AndroidBroadcastReceiver can be used to receive broadcasts and filter then with custom Intent Filters. Here is a small example which listens to a specific action and extracts data stored in the extras property under key "data":

AndroidBroadcastReceiver {
    id: receiver
    AndroidIntentFilter {
        actions: [
            "ACTION_SEND_STORY"
        ]
        dataAuthorities: [
            {
                host: "com.qt.story"
            }
        ]
        dataPaths: [
            {
                pattern: "/story",
                matchType: AndroidMatchPattern.PATTERN_LITERAL
            }
        ]
        dataSchemes: [
            "content"
        ]
    }

    onReceived: function(intent) {
        if (intent.extras.hasOwnProperty("storytext")) {
            console.log("Received story:", intent.extras.storytext)
        }
    }
}

AndroidBroadcastReceiver lives in the UI thread, and hence will not process received broadcasts when the UI thread is in a suspended state, meaning the app is not in the foreground. Instead, new broadcasts are placed on the event queue to be processed once the UI thread resumes. If you only need to receive broadcasts while the app is in the foreground, it is recommended to call stop() when the application is about to become suspended. Broadcast receiving can be restarted when the application becomes active again via start().

Here is an example of how to follow the application state and start/stop an AndroidBroadcastReceiver when it changes:

AndroidBroadcastReceiver {
    running: Application.state === Qt.ApplicationActive

    AndroidIntentFilter {

    }
}
