New Viewer for Android is available for testing:

https://evothings.com/uploads/evothings-studio/viewer/EvothingsViewer_1.4_160508_1938.apk

New in this version:

• Plugin for NFC: Add NFC plugin from Cordova #19
• REMOVED Plugin for Screen Orientation: Add plugin for screen orientation #20
• Updated iBeacon plugin for Android 6. https://github.com/evothings/cordova-plugin-ibeacon/releases/tag/3.4.1
• Updated BLE plugin for Android 6: https://github.com/evothings/cordova-ble/releases/tag/1.3.0
• BLE plugin updated on npm: https://www.npmjs.com/package/cordova-plugin-ble
• iOS code updated for Cordova 6: evothings-viewer build fails #21

Note that for BLE to work on Android, the user has to turn on Location in the Settings app. See this issue for details: evothings/cordova-ble#87

Test results this far:

• BLE scanning and Eddystone works fine on Android 5 and 6
• iBeacon scanning (ranging) works slowly, there is a delay before beacons are picked up (up to 1 minute), occasionally beacons are lost (tested on Nexus 7 Android 6.0.1, LG G2 Android 5.0.2)
• Tested iBeacon ranging on Nexus 6 Android 6.0.1 - iBeacon ranging works quickly

Tested iOS, found issues:

• FIXED On iOS the onReset method is not called. This is a Cordova bug. We can probably work around it by patching the Cordova code.
• FIXED Custom URL protocols were not working on pre-iOS 9 versions, fixed this by adding back deprecated URL handling method.
• FIXED The "location" background mode needs to be added manually (or to the iBeacon plugin) it is not present in the updated plugin code. On iOS 9, WebKit produces an exception if location preference is not present.
