Android Question DJI SDK

[madru]

Hi Erel,

any changes to see a DJI SDK 4.11.2 or 4.12 wrapper in the near future?

4.11.2 is the 1st version with Android Q support

What happens when you use the current SDK on Android 10? I'm pretty sure that I tested it with that version.

I get this after connection the remote to the phone:

java.lang.UnsatisfiedLinkError: No implementation for java.lang.String dji.midware.natives.SDKRelativeJNI.native_getUsbAccessoryAttachedString found () (Tried Java_dji_midware_natives_SDKRelativeJNI_native_1getUsbAccessoryAttachedString and Java_dji_midware_natives_SDKRelativeJNI_native_1getUsbAccessoryAttachedString__)
AT dji.midware.natives.SDKRelativeJNI.native_getUsbAccessoryAttachedString (Native Method,)

Android Mobile SDK 4.11.2 Release Notes
Added support for Android Q adaptation.

Did it crash?

Did it crash?

The drone or the software?

 

[Erel]

It is not too difficult to crash the drone when you build the controlling app. Happened to me when I played with auto takeoff in-house...

 

[udg]

Did you played and crashed the drone in your house???
Did the black-box aboard recorded your wife's reaction too? ?

Happened to me when I played with auto takeoff in-house...

I kindly like to suggest to remember the warnings inside the Library Thread

- Don't fly the drone indoors.

Sorry, couldn´t resist ;-)

 

[madru]

Did it crash?

Nope, the App keeps running, just the Java exception will be shown

 

[Erel]

Ignore it. You will see many errors in the unfiltered logs when using DJI SDK.

finally I got more info from my customer, he says that no USB connectivity between Phone & Remote is possible. The system ask to connect once or always, after selecting an option the Java Error is shown.
I can not verify the behaviour as do not have an Android 10 device currently, any idea?

 

[Erel]

Are you sure that the customer is testing it on a real device and not an emulator (or any other x86 VM)?

 

[madru]

Hi, sorry it takes always some time to get an answer from those guys.

he said they used a Samsung S10s for testing, what I can not verify.....

i will upgrade a Sony XA2 to LineageOS 17.1.x today for testing. Not the same device as the S10s but has 64bit, USB-C and Q......

keep you posted

 

[madru]

sorry, took some time.....

all good on a Sony XA2 with LineageOS 17.1.x, will organise a S10s for further testing .......

 

[madru]

all good on S10, no idea what they are doing wrong

Hello,

DJI has released a new version 4.13 of the SDK:

https://mvnrepository.com/artifact/com.dji/dji-sdk/4.13

This version now supports the relatively new Mavic Mini:

https://www.dji.com/de/mavic-mini

I would very much like to deal with the programming of an app that also supports this multicopter. I found Erel's thread:

https://www.b4x.com/android/forum/threads/dji-drones.75244/

However, I do not know which changes and additions to this example are necessary. I still lack the necessary knowledge for this. I have to rely on additional information. Otherwise this project will probably get stuck with the idea. I would therefore be very grateful for some information.

It is a mistake to post to existing threads. You should always create a new thread for your Questions/Issues.

The DJI Lib is based on 4.11. As of now there is no new version.

 

[Tempomaster]

I already did that:

https://www.b4x.com/android/forum/threads/dji-drones-library-update.111923/#post-755356

Unfortunately there was no reaction. So I used a thread with a similar topic.

 

[DonManfred]

So I used a thread with a similar topic.

And do the same mistake again? Posting to an existing thread is an mistake.

Valid for this thread and also valid for the other thread you linked.

 

[Tempomaster]

I just saw it that I posted in an old thread there too. I don't know how to add my contribution to a new thread?
