Crash: ServiceInfo.FOREGROUND_SERVICE_TYPE_MEDIA_PROJECTION

Question

I've got a video streaming app that has been running well for a number of years but I recently upgraded to

targetSdkVersion 28

I'm now seeing the following error...

java.lang.SecurityException: Media projections require a foreground service of type ServiceInfo.FOREGROUND_SERVICE_TYPE_MEDIA_PROJECTION

I followed the suggestions at Media projections require a foreground service of type ServiceInfo.FOREGROUND_SERVICE TYPE_MEDIA_PROJECTION in Android Pie and Q without any luck.

My manifest includes

    <uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
    <application
...
        <service
            android:name="screencast.StreamerService"
            android:foregroundServiceType="mediaProjection"
            android:enabled="true"
            android:exported="true"
            tools:targetApi="q"
            />
    </application>

The service is called like so...

package screencast;
final public class StreamerService extends Service implements Streamer.Listener {
...

I'm able to successfully request the permission (get a result code of -1 in onActivityResult like so...

   public void requestMediaProjection() {
        //Log.v(TAG, "requestMediaProjection");
        final MediaProjectionManager manager = (MediaProjectionManager) context.getSystemService(Context.MEDIA_PROJECTION_SERVICE);
        context.startActivityForResult(
                manager.createScreenCaptureIntent(),
                REQUEST_MEDIA_PROJECTION);
    }


int resultCode;
Intent data;
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    this.resultCode = resultCode;
    this.data = data;
    if (requestCode != REQUEST_MEDIA_PROJECTION) {
        return;
    }
    if (resultCode != Activity.RESULT_OK) {
        return;
    }
    enterStreamDescription();
}

I get the crash later on here when I call manager.getMediaProjection...

   public void startScreenCast(int resultCode,
                         Intent data,
                         int screenDensity,
                         List<Connection> connections,
                         AudioConfig audioConfig,
                         VideoConfig videoConfig,
                         Streamer.MODE mode,
                         File mp4,
                                MediaProjectionManager manager
    ) {

   ...

        mMediaProjection = manager.getMediaProjection(resultCode, data);

    }

Any suggestions are greatly appreciated. Thanks.
