Crash when starting a ProximityObserver without internet access

Goncalo-Almeida commented 6 years ago

Prerequisites

[X] My beacons have Estimote Monitoring enabled (Check it in the Estimote Cloud, or via app)
[X] My Android device/devices supports BLE and has Android OS version >= 5.0.0
[X] My Android device/devices have bluetooth enabled
[X] My app has Location Permissions granted

Basic information

Estimote SDK version: 3.3.0

Android devices affected: Vodafone VFD 510

Android OS version affected: Nougat 7.1.1

Beacon hardware version: G1.8

Description

I'm getting an exception that seems to be related with the lack of internet access to reach cloud.estimote.com. I stumbled upon this while testing the app without internet access. When I start the service without internet access the app crashes (stack trace at the bottom).

Steps to reproduce:

Create a ProximityObserver My code:

Notification notification =
            notificationHelper.getNotification("Beacon Scan", "Scan is running...", null);
    cloudCredentials = new EstimoteCloudCredentials(ESTIMOTE_APP_ID, ESTIMOTE_APP_TOKEN);
    proximityObserver = new ProximityObserverBuilder(mActivity, cloudCredentials)
            .withBalancedPowerMode()
            .withScannerInForegroundService(notification)
            .withOnErrorAction(onErrorAction)
            .build();

    venueZone = proximityObserver.zoneBuilder()
            .forAttachmentKeyAndValue("place", "some_place")
            .inNearRange()
            .withOnEnterAction(onEnterAction)
            .withOnExitAction(onExitAction)
            .withOnChangeAction(onChangeAction)
            .create();

    observationHandler =
            proximityObserver
                    .addProximityZone(venueZone)
                    .start();

Turn off Wi-Fi, and remove the SIM card (and any internet access)
Start the app

Expected behavior: Either a warning or some error for the developer to deal with.

Actual behavior: Application crashes

Hey @Goncalo-Almeida

Thank you very much for reporting this! It seems that some nasty unhandled exception is surfacing from our side, which definitely shouldn't happen. We'll investigate this and fix it in the next release :)

Regards, Paweł

pawelDylag commented 6 years ago

One more thing @Goncalo-Almeida - could you share with me the snippet with your onErrorAction?

Goncalo-Almeida commented 6 years ago

Sure =) The onErrorAction is just a copy of the example:

    private final Function1<Throwable, Unit> onErrorAction = new Function1<Throwable, Unit>() {
        @Override
        public Unit invoke(Throwable throwable) {
            return null;
        }
    };

pawelDylag commented 6 years ago

Thanks @Goncalo-Almeida ! I will look at this and will let you know about the progress :)

Goncalo-Almeida commented 6 years ago

Hi @pawelDylag, I saw you solved issue 32 and decided to test how this would impact the issues I have opened. I've just tested version 0.4.1 of the Proximity SDK and the app is no longer crashing (which is good =]) and is now throwing this exception:

I have created a sample app just to test the Proximity SDK, let me know that is of any use and send it to you.

Getting "Unable to resolve host "cloud.estimote.com": No address associated with hostname" Error.

pawelDylag commented 6 years ago

Hello guys,

Version 0.4.2 is now live - all uncaught errors should be now properly reported via onErrorAction. No crashes should occur from now on :)

Let me know about any other problems you encounter!

pawelDylag commented 6 years ago

Hey guys,

Pro tip to my future self - always check if you rebased and merged feature branch to master before releasing the new version 😆 Sorry for this, the version 0.4.3 should contain all the changes ^^

Regards, Paweł
