observeWifiAccessPoints suddenly doesn't work

[inijimenez]

my app was being used successfully observeWifiAccessPoints and observeConnectivity and suddenly observeWifiAccessPoints has stopped working (now never goes to "call" procedure).

This is my code:

@Override
protected void onResume() {
    super.onResume();
    // Register interest for two different actions related to power
    registerReceiver(powerMonitor, new IntentFilter("android.intent.action.ACTION_POWER_CONNECTED"));
    registerReceiver(powerMonitor, new IntentFilter("android.intent.action.ACTION_POWER_DISCONNECTED"));


    reactiveNetwork = new ReactiveNetwork();

    reactiveNetwork.observeConnectivity(this)
            .observeOn(AndroidSchedulers.mainThread())
            .subscribeOn(Schedulers.io())
            .subscribe(new Action1<ConnectivityStatus>() {
                @Override
                public void call(ConnectivityStatus connectivityStatus) {
                    Toast.makeText(MainActivity.this, "connectivityStatus", Toast.LENGTH_SHORT).show();
                    tvConnectivityStatus.setText(connectivityStatus.toString());
                }
            });

    reactiveNetwork.observeWifiAccessPoints(this)
            .observeOn(AndroidSchedulers.mainThread())
            .subscribeOn(Schedulers.io())
            .subscribe(new Action1<List<ScanResult>>() {
                @Override
                public void call(List<ScanResult> scanResults) {
                    Toast.makeText(MainActivity.this, "observeWifiAccessPoints", Toast.LENGTH_SHORT).show();
                    displayAccessPoints(scanResults);
                }
            });
}

Thank you for reporting the issue.
Does it happen all the time? I think it may be related to bug or bad design of Android SDK. I've seen on StackOverflow that people have similar problems with WiFi scanning.

I will check this out and try to fix it within library.

It looks that problem was caused by lack of WifiManager.SCAN_RESULTS_AVAILABLE_ACTION filter for BroadcastReceiver. Now it should work fine. Moreover, I've slightly updated sample app.
Fix will be available in the next release. If you want to verify it now, you can clone repository and check sample app.
