Sample app crash when using LocationProvider instead of minor about ble-indoor-positioning HOT 7 CLOSED

This should be fixed in PR #88. I've added your advertising data to the IBeaconTest.

That sounds quite strange.

The BeaconView will only use the minor if the specified beacon is an instance of IBeacon. The major and minor must be values between 0 and 65535 and thus can never be negative. If they are, please let me know how to reproduce the issue.

Besides that, even if the value of colorIndex is negative, that shouldn't be an issue (as we are using the modulo operator).

colorIndex %= MATERIAL_DESIGN_COLOR_RESOURCE_IDS.length;
return getInstance().materialDesignDarkColors[colorIndex];

You can see below that the minor is a negative value when create a beacon from
BeaconManager.getBeacon(macAddress, advertisingPacket.getBeaconClass());

And you can follow this scenario to check how the app crash :

1 -

2 -

3 -

4 -

It seems that there is something not finished yet in background, because when waiting a while everything works fine.

Could you let me know the raw byte array of advertising data from your beacon? I'll add it as a test case to figure out what could be causing the negative minor.

I also just realised that in Java, the % operator is not modulo, as I expected, but instead returns the remainder (according to StackOverflow). I'll add a fix for that.

Sure here you go, it's a kontakt beacon but not the pro version.

Java sucks.

Based on your data and the current implementation, I get the following when parsing as an iBeacon advertising packet:

IBeacon Advertising Packet (Proximity UUID: 9114d61a-67d1-11e8-adc0-fa7ae01bbebc Major: 25840 Minor: -28838 RSSI at 1m: -59)

Could you let me know which values you actually configured for that beacon?

from ble-indoor-positioning.

Sure here you go

Proximity UUID: 9114d61a-67d1-11e8-adc0-fa7ae01bbebc
Major: 25840
Minor: 36698
Advertising Interval: 625
RSSI @ 1m: -59
TX Power: 4dBm
