showToast "disconnected" #13

Run this sample on Huawei Tablet connected to remote controller of Phantom 4, the app shows "disconnected". Running DJIGo on it works well.

@hxl-dy Please provide the following infos for us to help investigate the issue:

Steps to reproduce the bug or crash issues(It would be great if you can provide this)
DJI Android SDK version you are using (Like Android SDK 3.4, etc)
Android device you are using (Like Samsung Galaxy Note 5, Nexus 5, etc)

if found it works when aircraft and controller both power on, but it failed when only controller power on. Android 5.1.1 on Huawei Tablet PLE-703L

Michael-DJI commented 7 years ago

@hxl-dy that's normal, "disconnected" is a hint message for the disconnect state of the drone

hexray-newbee commented 7 years ago

but in the code, it has three state:

Connected (both product and controller are running well )
only RC Connected (only controller connected )
Disconnected (neither product nor controller can be connected )

why the second state never show?

dji-dev commented 6 years ago

Hi there, The second state is an app logic that uses SDK with other data to conclude. This sample app only to show how to decode video. I have created this gist to show an example on how to use SDK to get "RC connected" state. https://gist.github.com/dji-dev/aabe8e204b326394aeb8930653610ce5 This is not related to this sample app so I will close this issue now.
