Thanks for reply!
About the OpenBrush, I use the pre-install one on device.
I've got the permission and allow and tried relaunch the OpenBrush.
But the Lab function export still fail.
About my developing APP.
1. I use the latest Wave SDK 5.5.
2. I've added the permission to my AndroidManifest.xml.
3. After allowed the permission (It does show the popup window), I also try many times to relaunch the APP.
4. I use the Unity Asset AVPRO to play the mp4 video
Or try the basic C# File IO to File.Copy the mp4 file to my APP folder.
Both of the behavior are fail. It showed access fail.
PS. I also try the File IO to check if the mp4 exist correctlly, the result is true. The file really exist.
Compare to normal Android APP (Pixel 4 with Android 13), after allowed the permission.
I could smoothly play the video from the download folder.
Please help me to check the result.
