I find typo of sample code at Readme.md

new DJIGerneralListener() is new DJIGeneralListener().

Hi,
I am trying to apply this tutorial with a Matrice 210.

The RC well connects to the UAV, but on the view of the activity ConnectionActivity, no video is showing. After debugging, I noticed that the function FPVDemoApplication.getCameraInstance() returns null. It means that the method getCamera() called on mProduct in the class FPVDemoApplication returns null.

I don't understand why, and I therefore hope that you could help me.

Thanks for your help,
Gabriel

可以成功注册但没有视频。请问是这个demo不支持M300RTK吗，还是我操作不对

Hey,

I need to implement autofocus fo my video app. I use this: camera.getCamera().setFocusMode(SettingsDefinitions.FocusMode.AUTO, null);

where exactly, or at what moment I need to include it.

I tried but my app is crashed after this...

Please help me

Hi,

I am unable to get this working with the N1 Video Encoder. Has anyone got that working or is that just for the Go App?

Cheers,

Attempting to compile and install this repo, we get:

db: failed to install ~/Android-FPVDemo/FPVDemo/app/build/outputs/apk/debug/app-debug.apk: Failure [INSTALL_FAILED_MISSING_SHARED_LIBRARY: Package couldn't be installed in /data/app/com.dji.FPVDemo-MK44tKyMCcOJymktlTpfvQ==: Package com.dji.FPVDemo requires unavailable shared library com.android.future.usb.accessory; failing!]

We removed the Manifest declaration requiring this capability, but then the app doesn't connect to the RC. We are running on Android 9. Any tips to make this work?

I imported the project, everything was working properly, but suddenly the preview stopped to update, since onSurfaceTextureDestroyed() called with no reason. I use M100 with manifold in the middle which. I run ./test -t on the manifold.

Hi, i'm deploying an app to view and broadcast the thermal image of this aircraft. I seen the example of XT2 Camera in Android but, the operation of the Mavic 2 Enterprise camera and the way to work with it is similar?

How I can change these images and access to thermal image's callback to send and show it?

Best regards !

Hello, when I run the sample code and try to capture pictures. It will toast "arror at accessing sd card". I have checked permissions and it does have the rights to write and read external storage.

• DJI Android SDK version you are using (Like Android SDK 4.3.2
• DJI Product you are using : spark
• Android system version you are using: Android 8
• Android device you are using: Pixle
• Android Studio version you are using : Android Studio 3.0

sometimes when i launch my app after check SDK.
it try to find my osmo camera, but sdk return me an unknow device (wifi connection)

I downloaded and created the Android-FPVDemo application.
but when I am trying to start shoot photo it is telling me "the command is not supported by the current firmware version"
What am I supposed to do?
I am using Mavic air 2, Firmware 01.01.0610.

thank you

Since my Phantom 4 is currently grounded, I tried to test this demo with a local setup of a controller connected via Lightbridge 2 to an A3 controller, with a Zenmuse X3 gimbal camera. The list here - http://developer.dji.com/mobile-sdk/documentation/introduction/product_introduction.html#supported-products - says this setup is supported.
I do get a Register Success message. However when I move to the next screen , I only see the 4 buttons and no video feed. Any ideas what could be going wrong? Or should I stick to using this with an able drone only?

比如我想使传回的视频流的分辨率为320x320，应如何实现

Hi,
I am new to Android Studio and Github. I tried to build the Camera Application of the DJI SDK 4.1.1 by using Android Studio 1.5 then with Android Studio 2.2, both without success.

First I wanted to confirm that my android device is compatible with the Phantom 4 Pro.
I downloaded the DJI Go 4 application and started it, input my email and password used in my dji account.
It works fine with the Phantom 4 Pro with the following devices: Zenpad 8.0 (Android 6.0.1) tablet, Galaxy Note 10.1 (2014 edition) running Android 4.4.2.
The PH4P is detected once the RC is turned on then I can enter the camera view and the video streaming starts once I turn the PH4P ON.

However, it didn't work on Galaxy S6 Edge (Android 7.0).

Using the Zenpad 8.0, I tried the 2 following methods:

Method 1:
By downloading the project from Github at: https://github.com/DJI-Mobile-SDK-Tutorials/Android-FPVDemo
I signed in and clicked "Clone or download" button, then "Download Zip".
I unzipped the archive and imported it in Android Studio. 2 messages appeared:

• One error message that says Android Studio couldn't find Git. So I installed it and it fixed the issue.
• And error message "Invalid VCS root mapping: The directory is registered as
• A warning message "Frameworks detected: Android framework is detected in the project." with a "configure" link. When clicking the link, a configure window appears. If I click the OK button in the window, "Android-FPVDemo" appears in the "Android" on the left side of the IDE, but there are no project items displayed (no source file, no resource ...).
  I opened the project structure window, in the Project section there is no SDK selected. In the Modules section, there is no module neither. Same for the Libraries section.

What am I missing here ?

Method 2
By following step by step the FPVDemo tutorial available at:
https://developer.dji.com/mobile-sdk/documentation/android-tutorials/index.html

I requested a DJI Key and inserted it in the manifest.xml file.

When I compile the application from android, the connection activity starts on my tablet.
Then I unplug the tablet from the PC and while the remote controller is OFF I connect the tablet to the remote controller, and turn the RC power ON.
I select the FPVDemo to access the USB. There is a "Register Success" toast message showing up, but nothing happens and the connection activity is not displayed.

From the previous SDK, I checked the following points:

• The tablet was connected to internet through a wifi router
• The app setting on the tablet has no app defaults set
• I used several USB cables to connect the tablet to the RC but I still couldn't start the FPVDemo app

I could track the issue to DJISDKManager.getInstance().startConnectionToProduct(); in FPVDemoApplication.java returning false, but I couldn't get further information regarding the cause.

Thanks for your help!

run demo code, can't connect to remote control.

m100,firmware:v1.5.8

the app-key is correct and pass the sdk validation.

Hi, I am a graphic designer, I want to help others in graphic design.

After I reviewed your project, you have no logo on this project. Therefore I want to contribute to this project by creating a new logo / icon. what do you think?

I saw that there is a DJIAoaControllerActivity but it has no references in the github. There is no java.class with such name.

Best Reggards

I cloned the repository and tried to run the app on my phone. The App instantly crashes.

The app crashes when

1. it is connected to my computer / AndroidStudio
2. to the DJI remote and
3. not connected at all.

Android: Android 13

Android Studio: Android Studio Dolphin | 2021.3.1 Patch 1 | Runtime version: 11.0.13+0-b1751.21-8125866 amd64

I also had this problem when following your tutorial for the UXSDK Demo and creating the App from scratch.

Does compatibility problems with the UXSDK elements exists?

Hi, the app say me only RC connected

Is this issue about bugs or crash issues of the Sample Code?

Demo not working

• Description of the issue.

• Steps to reproduce the bug or crash issues(It would be great if you can provide this)
  No crash

• Crash logs (If you can find it, it would be very helpful)
  No logs

• DJI Android SDK version you are using (Like Android SDK 3.4, etc)
  4.9

• DJI Product you are using (Like Phantom 4, Mavic Pro, etc)
  Mavic Pro

• Android system version you are using (Like Android 6.0.1, Android 5.1.1, etc)
  Android 8.1

I cloned the demo in here. I renamed the package so that it matches my registered Application. I provided the proper SDK key. The key was accepted, registration successful upon start of application.

The Android phone is connected via USB with the RC. The drone is on and connected with the RC. The app shows "Status: No product connected". The "OPEN" button is greyed out. Whenever I connect the RC via USB with the phone an new instance of the app is loaded.

What am I doing wrong here? What am I supposed to do right?

Hello, I am writing to ask you about the reference system of the thermal camera of the Mavic 2 Dual Enterprise.

I'm looking at your documentation and I can't find anything about it. The system you use is as follows? Where the ranges of the X and Y axes are [0-1].

Thanks in advance and best regards !

The app does not seem to work completely with Phantom 3 Standard. While I am able to see through the drones camera all other functionality of the app seems to be lost. I.e. capture and video mode do not save to the drone's SD card and instead of saying the model of drone connected it says disconnected (it also puts up two toast messages that say disconnected upon opening the app). Lastly, if you open the app connected to the controller's wi-fi it will say that the SDK registration failed.

More generally I was curious if DJI or anyone have put out tutorials specifically on coding for drones where you have only a wi-fi connection to the controller. Alternatively is it possible to somehow hardwire the phone into the phantom 3 standard controller.

Any help is greatly appreciated.

I want to receive the YUV data and do something with it. Then I followed the document and wrote such code:

mCodecManager.enabledYuvData(true);
mCodecManager.setYuvDataCallback(this);

while the MainAcitivity implements DJICodecManager.YuvDataCallback, and when clicking a button the code above would be executed.

But now as long as I click the button, the preview of the TextureView will be stuck. Even if I commented the code mCodecManager.setYuvDataCallback(this), the code mCodecManager.enabledYuvData(true) would still make the preview stuck when I click the button.

So how to deal with the problem and receive the YUV data correctly?

My devices' information:
UAV: Phantom 4 Pro
DJI SDK version: 4.5.1
Android System version: 7.0
AS version: 3.1

I have a question about Dji mobile on Android System.

I used a Android device and run Dji go ,then set open EXT port and App-output-mode from LB to EXT ,The device can display video.

However when I run the FPVDemo ( download from the GitHub DJI-SDK ) by Android Studio ,it dosen’t work, I can not see anything from the preview.

First, I can make sure that the app is register success and jump to the MainActivity.class,
Second, the CameraReceivedVideoDataCallback has no data callback;
Third, the environment like that.

Env:Huawei M3 + A3 + LightBridge 2 + 禅思X5 + S900

What do I need to set in this demo to display the video ?

when I run the demo,why there is a problem in application? says that:

Error:(48, 115) 错误: <匿名com.example.myapp.FPVTutorialApplication$1>不是抽象的, 并且未覆盖DJISDKManagerCallback中的抽象方法onGetRegisteredResult(DJIError)

Can you explain it?

Hi to all,
I'm developping an mobile application with DJI SDK in Android studio.
I use Fabric for report crash
I usually get crash reports of this kind:

So how can i solve this problems ? 

THANKS IN ADVANCE

After app deployment using our api key, the app starts and connects to the mavic 2.
The live video feed works, but when trying to record a video or take a capture, the error
`"dji error camera is busy or the command is not supported in the current state"

gets thrown.
Is there a workaround, which allows image capture during live video stream for the mavic 2?

I am trying to dynamically give a GPS coordinate to the FollowMeMission.

When I called startSimpleFollowMe its giving me an error "The aircraft is not in the air.".
Here are the two methods which I used for a
public void updateSimpleFollowMe(){
if(fmmo == null){
fmmo = MissionControl.getInstance().getFollowMeMissionOperator();
}
final FollowMeMissionOperator followMeMissionOperator = fmmo;
if(followMeMissionOperator.getCurrentState().equals(FollowMeMissionState.EXECUTING)) {
followMeMissionOperator.updateFollowingTarget(new LocationCoordinate2D(homeLatitude + 100 * GeneralUtils.ONE_METER_OFFSET, homeLongitude),
new CommonCallbacks.CompletionCallback() {
@OverRide
public void onResult(DJIError error) {
if (error != null) {
setRunningResultToText(followMeMissionOperator.getCurrentState().getName().toString() + " " + error.getDescription());
} else {
setRunningResultToText("Mission Update Successfully");
}
}
});
}
}
public void startSimpleFollowMe(){

    if(fmmo == null){
        fmmo = MissionControl.getInstance().getFollowMeMissionOperator();
    }
    final FollowMeMissionOperator followMeMissionOperator  = fmmo;
    if (followMeMissionOperator.getCurrentState().equals(FollowMeMissionState.READY_TO_EXECUTE)){
        fmm = FollowMeMission.getInstance().initUserData(homeLatitude, homeLongitude,15);
        followMeMissionOperator.startMission(fmm, new CommonCallbacks.CompletionCallback() {
            @Override
            public void onResult(DJIError djiError) {
                if(djiError != null){
                    setRunningResultToText(djiError.getDescription());
                } else {
                    setRunningResultToText("Mission Start: Successfully");
                }
            }
        });
    }
}

when I connected the RC to the mobile device , the demo crashed immediately.

Think 4.11.1 fixed the problem. Need to change to 4.11.1 not 4.11

Hello,

When exiting, I receive the following error:

Service has leaked IntentReceiver dji.internal.version.c@4309fc40 that was originally registered here. Are you missing a call to unregisterReceiver()?

It says that the IntentReceiver has been registered somewhere in "initParams", called by "DJISDKManager.initSDKManager()".

Could you tell me which IntentReceiver is registered by "initSDKManager()" and how to unregister it?

Thanks in advance!

Hi,

There is some simple way to decode the received H264 raw image to display it in OpenCV, without using DJI decoder?

Thanks in advance.

You should mention in the README that the sdk is built with android level 22, because the project must also be built with android level 22. By default android studio creates a project using the latest built tools (at the moment it would be compileSdkVersion 23).

Also, the sample project android level is 23 so it won't run successfully.

Is this issue about bugs or crash issues of the Sample Code?

Yes

Hi, I am using the DJI OSMO+ gimbal for developing an Android Camera application and I noticed that there is a huge difference in CPU usage when using the official DJI Go app (CPU Usage ~10% to 15%) from the Android PlayStore vs. DJI FPV Demo app (CPU Usage ~40% to 50%). Here are some details re my development environment:

1. Which DJI Product you are using? - DJI OSMO+
2. Which DJI SDK you are using? - DJI Android Mobile SDK V4.4.1
3. Which Android Device and Android System version you are using? - Device: Pixel XL; Android System: 7.1.2 (Android N)
4. Which Android Studio version you are using? - Android Studio: 3.0.1; JRE: 1.8
5. A short description of your problem includes debugging logs or screenshots. - I noticed that there is a huge difference in CPU usage when using the official DJI Go app (CPU Usage ~10% to 15%) from the Android PlayStore vs. DJI FPV Demo app (CPU Usage ~40% to 50%). I used the "adb shell top" command to profile CPU usage.

Note that CPU usage stays ~30% even on the ConnectionActivity (i.e. before even starting the video decoding in the MainActivity). Seems like a whole lot of junk on my device hogging the CPU for no reason...

Questions: - Does anyone know what could be the reason behind this huge CPU usage difference? - Please advice on how I can reduce the CPU usage when using the DJI FPV Demo app; kindly share code snippet or update Github with sample code.

Thanks!

mavic 2 , 运行官方 FPVDemo ，切换拍照模式 ，或者录制模式都成功，但是点击拍照，或者开始录制，都会提示 Camera is busy or the command is not supported in the Camera's current state，请问什么原因

Not a but, just a question: I played a bit with the DJIVideoStreamDecoding example. I noticed, that whenever yuv decoding is switched on

 mCodecManager.enabledYuvData(true);
 mCodecManager.setYuvDataCallback(this);

neither of the views (texture, surface) is updated anymore.

This observation is backed up by this series of traces after the switch above:

D/SurfaceUtils: disconnecting from surface 0x7d6e1a6010, reason disconnectFromSurface
D/DJIDecodeServer: releaseDecoder() end
E/libEGL: call to OpenGL ES API with no current context (logged once per thread)
E/GLContextMgr17: OpenGL destoryed
E/GLYUVSurface: OpenGL destoryed
E/Lightbridge: startStream videoCtlobjet == NULL
D/DJIVideoDecoder: stopVideoDecoder()

Does that mean I can't video preview and yuv decode at the same time? Then I'm wondering, how I could flight if I just want to obtain the video for post processing purposes.

There is no getProductInstance() and getCameraInstance() defined in MainActivity.Java.

So one will need to add below in Mainactivity.java:
public static synchronized DJIBaseProduct getProductInstance() {
if (null == mProduct) {
mProduct = DJISDKManager.getInstance().getDJIProduct();
}
return mProduct;
}

public DJICamera getCameraInstance() {
    return (DJICamera)this.mComponentMap.get(DJIBaseProduct.DJIComponentKey.Camera);
}

PS: Please let me know, if I am wrong anywhere :)

The video recording and image capturing doesn't work on phones that don't have SD cards.

手机root和关闭selinux权限，运行demo，闪退

设备为 精灵4 Pro，目前 SDK 的拍照功能不能使用，调用 captureAction 时都是 "Not Support"；回退到之前的 SDK 版本（4.2.1）也还是不能，是否是因为设备固件升级所导致的问题？

Hi, I am a graphic designer, I want to help others in graphic design.

After I reviewed your project, you have no logo on this project. Therefore I want to contribute to this project by creating a new logo / icon. what do you think?

Running of this application saves images/videos into a drone's SD card.
How to save them in an android phone directly

Is this issue about bugs or crash issues of the Sample Code?

and I used the FPVDemo for development my own app,but where filesystem path in my device can get the photo? and can I setting the photo path ?

Yep, then please delete this template and provide the following infos for us to help investigate the issue:
