java.lang.NoClassDefFoundError: Failed resolution of: Ldji/v5/common/error/DJIWaypointMissionError$Error;

[Tin-moon]

Hi, I get this error, most often when the mission is completed, or the return home button is pressed.
Used:
DJI RC Plus 2 and DJI Matrice 4T
SDK 5.17.0
What could be the problem?

Agent comment from YIGUI LIU in Zendesk ticket #171401:

Dear Developer,

The crash is caused by the failure to find the class dji.v5.common.error.DJIWaypointMissionError$Error, which is likely due to incorrect dependency configurations for SDK-related resources. You can refer to the sample code to configure the dependencies correctly.

Use the same version configurations as the sample code:

• Java Runtime：17
• Kotlin：2.1.0
• Gradle：8.12
• Android Gradle Plugin：8.7.0
• minSdkVersion：24
• targetSdkVersion：35

Add android:extractNativeLibs="true" to the application node in the AndroidManifest.xml file under the App directory.

According to feedback from other developers who encountered the same error, this issue is caused by an incorrect call sequence of the MSDK initialization interfaces.

Please follow the integration tutorial and the call sequence in the sample code:

1. Call com.cySdkyc.clx.Helper.install(this)first in attachBaseContext of the Application class;
2. Then call SDKManager.getInstance().init();
3. Only call other functional interfaces after the MSDK initialization is successful.
   Integration Tutorial: https://developer.dji.com/doc/mobile-sdk-tutorial/en/quick-start/user-project-caution.html

In addition, you can test whether the issue can be reproduced using the MSDK sample app, and refer to the code implementation in the sample code for troubleshooting.

Best Regards,
DJI Innovations SDK Technical Support Team
