Frequently Asked Questions¶

APP¶

Please note that we only guarantee the released sample code as a verified and functional app building environment. If you find a critical issue with your app, you can use the same environment as our released sample code to build your app and test again.

Common issues when building the Android App¶

If you run into an error from gradle tools when you are building the Android App. Find the Cordova-Android release note below.

• Due to the recent changes Google made to Android Studio, Cordova Android now requires Gradle to be installed as a standalone dependency for Android development on all platforms. You can do so by following these instructions at gradle.org.

You can try to install the latest gradle tools and run ionic cordova build android --prod again.

Deleted device still shows on the admin page¶

In order to maintain all historical events and status for devices throughout its lifecycle, when admin users or end users delete a device, the trash bin icon is removed to prevent repetitive deletion and events and device status are kept for future investigation. When the device is re-provisioned, its events and status would be aggregated under the same device entry.

Can't add a device in China¶

The default NTP server is connecting to Google. If you are adding a device in China, you need to change the NTP server in firmware config file to a NTP server that won't be blocked by Great Firewall.

If you want to support multiple NTP servers(more than the default one), you can implement it in the platform_utils_sync_time_from_ntp() function.
