ClassNotFoundException: DataBatteryActiveStatus

[JonasVautherin]

I keep getting the exception below, and I don't seem to find DataBatteryActiveStatus in the jar files coming with the SDK. Where is it supposed to be?

The DataBatteryActiveStatus class is also obfuscated. If you need this functionality, could you please provide the application scenarios for us? Our product manager will review it and this might become a new functionality for next version.

Best & Thank you

We don't use it at all. The SDK is sending us this error every few seconds. It looks like something is trying to access DataBatteryActiveStatus internally and does not find it (supposedly because it is obfuscated).

So it looks like a bug on the SDK's side.

[SilverChangjian]

Sorry, my mistake. The reason why this error occurs is that the battery is not activated and pushing data for notifying the DJi Go App to activate it. For the SDK, some internal classes (like DataBatteryActiveStatus) are obfuscated. And that's why the error type is ClassNotFoundException. For solving this problem, I suggest you could use the DJI Go App to activate the battery (just open the DJI Go App and it will do it automatically). Then there will be no data for battery's activation notification.

Thanks for reporting bugs. We will go through all the corner case for using the SDK.

Best wishes

It didn't solved by opening DJI GO application. we still have same error occurring every second.

[JonasVautherin]

Do you happen to have any news about that problem?

[SilverChangjian]

There will be a 2.4.1 version for this problem. I will be solved in that version

[JonasVautherin]

Disappeared in 2.4.1. Thanks!
