ClassNotFoundException Didn't find class "dji.v5.manager.interfaces.SDKManagerCallback" on path
Problem
I am trying to create a bare-bones app that imports the DJI msdk v5.15.0, but regardless of adjusting many settings, I always get Failed resolution of: Ldji/v5/manager/interfaces/SDKManagerCallback in the runtime.
Here is my current android project repo: https://github.com/bdlilley/seabase

Versions
- Host: macbook pro M4 max running Sequoia 15.5
- Android studio: Android Studio Narwhal Feature Drop | 2025.1.2 Patch 1
- Target device: Samsung Galaxy Tab A9 running Android version 15, kernel 5.10.218-android12-9-30958166
Things I've Tried
- Followed all instructions in https://developer.dji.com/doc/mobile-sdk-tutorial/en/quick-start/user-project-caution.html#edit-the-androidmanifest-xml-file
- I have tried each step word-for-word and end up with the same failures
- I realize my linked repo is a little different than the docs steps - but I have tried them all with the same results
- Tried the "empty project with MSDK integrated" from the links in that doc - https://terra-1-g.djicdn.com/fee90c2e03e04e8da67ea6f56365fc76/SDK%20%E6%96%87%E6%A1%A3/MSDK/5.11.0/SDKSample.zip - I get the same results with this project as I do the one I linked in github
- Tried all suggestions from claude code and chatgpt - these mostly revolved around modifying proguard rules and changing multidex configurations to force the correct classes into the apk
- apk analysis
- I found that SDKManager does exist in the APK in classes3.dex but with a size of 8b
Any help in getting this to build, deploy, and load the DJI sdk would be greatly appreciated!
Agent comment from YIGUI LIU in Zendesk ticket #154404:
Dear Developer,
It is recommended that you first run the MSDK Sample App successfully to facilitate subsequent comparison and verification of issues.
- Run Sample Code: https://developer.dji.com/doc/mobile-sdk-tutorial/en/quick-start/run-sample.html
Then, based on the error log you provided, it is found that the main issue is the failure to find the class: dji.v5.manager.interfaces.SDKManagerCallback.
It is recommended that you troubleshoot the problem through the following points:
- Version configuration of the development environment The version configuration of the development environment needs to be consistent with that of the MSDK v5.15.0 Sample Code:
- Java Runtime: 17
- Kotlin: 1.8.10
- Gradle: 7.6.2
- Android Gradle Plugin: 7.4.2
- minSdkVersion: 24
- targetSdkVersion: 34
- NDK_VERSION = 21.4.7075529
- Error with
com.cySdkyc.clx.Helper.install(this);On the "Run/Debug Configurations" page of Android Studio, check the "Always install with package manager" option. Failure to do so will result in the installation failure ofcom.cySdkyc.clx.Helper.install(this). - SDKManager error: Failed to find the class
dji.v5.manager.interfaces.SDKManagerCallbackat runtime - Check whether the SDK dependency is correctly imported.
- Refer to the SDK Sample and check if
com.cySdkyc.clx.Helper.install(this)is called in theApplicationclass. Do not call any MSDK-related interfaces before invoking this method. - Switch the execution of
SDKManager.getInstance().init()to an Activity or to the main thread.
Best Regards,
DJI Innovations SDK Technical Support Team

I managed to find the solution to this problem. I have a multi-module project, and the MSDK module is in a separate module, which was frequently generating this error and the SDKManager constructor error. The solution to this problem is:
Install com.cySdkyc.clx.Helper.install(this) in the attachBaseContext. Don't install or initialize the SDKManager immediately, as this will cause the error.
Create a handler in the main Activity with a minimum delay of 5000, and that's it.
Problem solved.
