I'm following the tutorial from here:
https://codelabs.developers.google.com/codelabs/hello-beacons/#6

But after following it step by step I'm getting an error on this line:

                .setFilter(new MessageFilter.Builder()
                        .includeNamespacedType("some_namespace", "some_type")
                        .build();

Error:

/Users/xxxxx/AndroidStudioProjects/hello-beacons/HelloBeacons-Subscribe/app/src/main/java/com/google/android/gms/nearby/messages/samples/hellobeacons/MainActivity.java
Error:(198, 33) error: ')' expected

On '7. Subscribe to beacon attachments using Nearby' section it is highlighted that we create mSubscribed field to 'not bother replacing that subscription with a new one.'. Appropriate filed is created, stored on rotation and checked before create a subscription. But it is actually never set to true. I think, we should set it up on ResultCallback callback:
@Override public void onResult(@NonNull Status status) { if (status.isSuccess()) { Log.i(TAG, "Subscribed successfully."); mSubscribed = true; startService(getBackgroundSubscribeServiceIntent()); } else { Log.e(TAG, "Operation failed. Error: " + NearbyMessagesStatusCodes.getStatusCodeString( status.getStatusCode())); } }

the correct method:

SubscribeOptions options = new SubscribeOptions.Builder() .setStrategy(Strategy.BLE_ONLY) // Note: If no filter is specified, Nearby will return all of your // attachments regardless of type. You must use a filter to specify // a particular set of attachments (by type) or to fetch attachments // in a namespace other than your project's default. .setFilter(new MessageFilter.Builder() .includeNamespacedType("some_namespace", "some_type") .build()) .build();

when i turn on the app if within a few seconds (maybe 10sec) it tries to find beacons but after that even if i turn off the beacon or turn on new beacons there is no response from the app . Unless i exit to main screen(home screen) and turn on the activity again is when the changes to beacons are detected. Is there some issue with the code or is it hardware. I have followed the code lab to the end. I use nexus 7 2013(android 6) for the app. And beacon simulator on moto g4 (android 7)

In onSaveInstanceState() the super.onSaveInstanceState(outState); must be called for last.

The correct code is:

@Override
    protected void onSaveInstanceState(Bundle outState) {
        outState.putBoolean(KEY_SUBSCRIBED, mSubscribed);
        super.onSaveInstanceState(outState);
    }

I cant get the hardware to connect with my android smartphone using Googles (beacon tool) to connect I get nothing from unregistered or registered! the blue tooth is receiving broadcast pings but nothing else!
what next?

I have tried replacing certain oarts of this hello beacons code....but facing issues.
Could some one help me in this regard by providing replacements for deprecated APIs

On the step 9 it is stated that we should

open HelloBeacons-Display-Messages.

but really in this step we are working with 'HelloBeacons-Finished' project
