• DJI Android SDK 4.3.2
• DJI Product :DJI Spark
• Android system version: Android 6.0.1
• Android device : Nexus 7 (2013)
• Android Studio version: Android 2.2

Could you please help out?

when i open the project with android studio : its give me this error :

Failed to resolve: com.dji:dji-uxsdk:4.13.1

UXSDK能不能有像DJI Pilot App中manual flight那样的设置组件（右上角）？

Recently updated to 4.10, and then had to change my project to suit it. I removed the "old way" of putting the camera in (TextureView), with this new "easy" way of just inserting FPVWidget into my xml.

Now there's text rendered on top of my camera view, with the words "Phantom 4 Camera" (I'm using a Phantom 4). Looks like some sort of debugging assistance, but it's still there when I build my app with release signing.

Looking through the FPVWidget.class file in Android Studio, the text is clearly inserted onto the UI in private void initTextOverlay(). But I see no method calls for FPVWidget to remove this text.

Is this just supposed to be there all the time? I notice this text is not present in any of the updated tutorial screenshots.

gz#24592

Installation failed with message Failed to finalize session : INSTALL_FAILED_MISSING_SHARED_LIBRARY: Package couldn't be installed in /data/app/uxsdkdemo.dji.com.uxsdkdemo-l9gVWo4izq_fP6SusITP4g==: Package uxsdkdemo.dji.com.uxsdkdemo requires unavailable shared library com.android.future.usb.accessory; failing!.
It is possible that this issue is resolved by uninstalling an existing version of the apk if it is present, and then re-installing.

WARNING: Uninstalling will remove the application data!

Do you want to uninstall the existing application?

I get this warning when i try and run the application.

I tried removing <uses-library android:name="com.android.future.usb.accessory" />
as suggested on another forum and while this allowed the app to install on the AVD it caused the app to crash after requesting permissions.

I am trying to modify the UXSDKDemo aplication so that I can send the drones current coordinates in real time to another aplication so I can show it using VR, now in order to do that I first needed to get the coordinates and to make sure they are correct I decided to modify the UXSDKDemo to show them using a toast message but when I did it it just showed the cooridantes as "NaN".
I am not sure if I made some kind of mistake and called the method I made that was getting the coordiantes and the wrong place or maybe it isn't possible to get this information using the UXSDKDemo.

These were the methods (from the DJI SDK) i used in order to get the data.

    `  FlightControllerState currentState = new FlightControllerState(); `
    ` LocationCoordinate3D location = currentState.getAircraftLocation();  `
    ` double lat = location.getLatitude();  `
    ` double lng = location.getLongitude(); `
    `  float alt = location.getAltitude(); `

I called my method in the MApplication class, in its onCreate method, like this:

public void onCreate() {
super.onCreate();
demoApplication.onCreate();
demoApplication.showLocation();
};

My biggest concern is that for some reason it is not possible to get the data on longitude, latitude and altitude in the UXSDKDemo, hope you can help me out! Thanks in advance!

Hi,

The Bintray service is not working any more: https://jfrog.com/blog/into-the-sunset-bintray-jcenter-gocenter-and-chartcenter/
but it is used in the Demo code: UXSDKDemo/app/build.gradle line 5
maven { url 'https://mapbox.bintray.com/mapbox' }

This causes a build error:
Could not HEAD 'https://mapbox.bintray.com/mapbox/com/dji/dji-sdk/4.15/dji-sdk-4.15.pom'. Received status code 403 from server: Forbidden

android app开发中，将使用MSDK和UXSDK由V4.8升级到V4.10(或者V4.9)时，程序编译报错：..\app\build\intermediates\exploded-aar\com.dji\dji-uxsdk\4.10\res\layout\layout_manual_focus_widget.xml
Error:(27, 35) No resource found that matches the given name (at 'layout_above' with value '@id/vertical_wheel_max').
该怎么解决？ gz#24813

DemoApplication里registerApp(getApplicationContext(), mDJISDKManagerCallback)，这里mDJISDKManagerCallback为null，mDJISDKManagerCallback是在后面new的，请问是SDK内通过其他方式调用了registerApp吗？当我先new mDJISDKManagerCallback再registerApp(getApplicationContext(), mDJISDKManagerCallback)，这时候一直报错Attempt to invoke virtual method 'android.content.res.Resources$Theme android.content.Context.getTheme()' on a null object reference

Android studio 3.1.1 Failed to resolve: multidex

Using Android Studio 3.2
Emulator: Pixel running API 27

This happens in both the UXSDKDemo and the sample.UX.SDK apps.

Side Note:
It doesn't appear as if the developers of these demos are using the latest Android Studio (3.2) or Build Tools (28). The demos require a lot of tweaks to the gradle files to even compile them. Please keep your software up to date! Thanks!

Hello, I'm having troubles with UI SDK. I haven't tried exactly this sample. I have my own app, where I'm using exactly the same layout. I always get the following error:

java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.Integer dji.sdk.codec.DJICodecManager.getVideoHeight()' on a null object reference

It always happen if the device is not connected to the controller and activity is paused and then resumed (starting new activity and then go back, put the app to background and then back)

Full log here.

• DJI Android SDK 4.4.1
• Android system version: Android 8.1.0
• Android device : Nexus 5x
• Android Studio version: Android 3.2

Could you please help out?

Hello,

I've been attempting to follow this demo, but I've been having the application crash no matter what I do. I've added logs and sleeps to the on create method to try and verify where it crashes, and the crash is given before the logs/sleeps even come into play. Based on this, and the error logs which display only on the android hardware/library code when I plug it into a phone, I think there may be some kind of incompatible code with new android software for android studio.

• Steps to reproduce the bug: download the code from github and run it as described in the tutorial.
• Android Studio: 3.0
• DJI Android SDK version you are using : sdk given from tutorial/most recent downloads
• DJI Product you are using: Mavic Pro (Not connected to studio at the moment)
• Android system version you are using: Android 6.0.1
• Android device you are using : Galaxy J2 Prime

Hopefully this helps, and I look forward to hearing on this issue soon.
