Android SDK issue?

chienvh · March 1, 2017, 9:24am

Hi all,

I have an issue when receiving the pull messages on Android devices. Normally we cannot pull the msg from ibeacon to mobile, but after restart the mobile, I can get the message displaying on my mobile.
Can anyone please help to let me know what happens with my app? Does the issue come from SDK?

Can you share some more information? Android device, Android OS version, code snippet, debug logs[1], SDK version, etc.?

[1] EstimoteSDK.enableDebugLogging(true);

Hi Heypiotr,

I got the issue on android version 6.0 and 6.0.1. The devices are Samsung S6, honor, nexus 5/7.
Below is the code we were thinking it generated the errors:

BeaconManager beaconManager = new BeaconManager(getApplicationContext());
beaconManager.setMonitoringListener(monitoringListener);
beaconManager.setRangingListener(rangingListener);
beaconManager.connect(new BeaconManager.ServiceReadyCallback() {
    @Override
    public void onServiceReady() {
        // Start monitoring a region
        Region enterRegion = new Region(uuid + ":" + beacon_id, UUID.fromString(uuid), nearestBeacon.getMajor(), nearestBeacon.getMinor());
        beaconManager.startMonitoring(enterRegion);
    }
});

Looking forward to hearing from you soon.

The code looks just fine, any chance for the debug logs?

UPDATE: actually, on a second look, the snippet’s a bit incomplete, e.g., can’t see your ranging/monitoring listeners, and in the enterRegion you’re using nearestBeacon and uuid variables which I also can’t see where they’re coming from and what they are. Debug logs will still be helpful too (:

Appreciated your quick response!

I would like to share the log which generates from App debugs. I’m trying to get the log from SDK, will share to you too once I have it.

Hi!

Could you provide us with the snippet of the MonitoringListener and RangingListener that you use?
And we can’t say from the code you posted if you’ve initialized the RangingListener.

Thanks!

Hi Raphael,
There is the piece of code. Appreciated any suggestions.

Hi there,
Waiting for your ideas please…

chienvh · March 28, 2017, 7:47am

Hi @heypiotr,
Could you please help response on my issue? There is blocker for us now. Thanks!

heypiotr · March 30, 2017, 10:43am

Sorry for the long wait!

The one potential source of problems I see is, in your monitoring listener:

if (!list.isEmpty() && !region_id.contains("null")) {
    Beacon nearestBeacon = list.get(0);
    if (nearestBeacon == null) {
        return;
    }
    if (hmIBeaconMessage.containsKey(region_id)) {
        // Push Notification
        pushBeaconDisplayAt(3, region_id, Const.BeaconPriority.SELF);
        pushBeaconDisplayAt(1, region_id, Const.BeaconPriority.SELF);
    }
}

From our onEnteredRegion documentation: “This list may not reflect all beacons around that are matching given region.”

Hence, I’d suggest simply … getting rid of most of these “ifs”, e.g., replace all of the code above with simply:

pushBeaconDisplayAt(3, region_id, Const.BeaconPriority.SELF);
pushBeaconDisplayAt(1, region_id, Const.BeaconPriority.SELF);

In general though, I think this code is much more complex than it could be, which can lead to all sorts of little problems. I assume the intention is simply to show some kind of notification when you enter range of some beacon? Is that right?
