Challenges with File Generation and Logging in Android Scoped Storage Using DJI SDK

Hello DJI Developer Community,

I am encountering a significant issue with the DJI SDK in relation to Android's Scoped Storage rules, specifically when trying to generate KMZ files and write to log files in the /sdcard directory. I seek your insights and suggestions on how to navigate this problem.

1. Issue Overview: My application, which integrates the DJI SDK, is facing permission-related problems in Android 10 and above due to Scoped Storage restrictions. The app fails to generate KMZ files and write to log files in the /sdcard directory without the MANAGE_EXTERNAL_STORAGE permission.

2. Code Examples: Here are the key parts of my code where the issues occur:

• KMZ File Generation (in convertToSDKFormat method):
  WPMZManager.getInstance() .generateKMZFile(waylineKMZPath, waylineMission, missionConfig, template)
• Log File Path Initialization (in PPALController.class):
  static { try { System.loadLibrary("ppal-jni"); initLogPath("/sdcard/ppal.log"); } catch (UnsatisfiedLinkError var1) { Log.e("PPALController", "Couldn't load lib-ppal-jni! e=" + var1.getMessage()); } }

3. Error Messages: I am receiving permission denied errors when trying to access /sdcard.

4. Scoped Storage Impact: The issue appears to stem from the Scoped Storage implementation in Android 10+, which restricts access to directories like /sdcard.

5. Current Workaround: Using MANAGE_EXTERNAL_STORAGE seems to solve the problem, but I am aware this permission is not recommended for widespread use and might not align with Google's guidelines.

6. Seeking Guidance: I would greatly appreciate any advice on how to handle file generation and logging within the Scoped Storage constraints, specifically for apps using the DJI SDK. Are there best practices or alternative approaches recommended for this scenario?

7. Potential Solutions: I am considering using app-specific directories or modifying the SDK's file management methods. I welcome feedback on these ideas or any other solutions.

Thank you in advance for your help and suggestions!
