Public path of Android Q

I have tried to write the file into "/mnt/sdcard" path its return error. Code on JNI layer(C++) using normal fopen("new.txt","w")

And also tried the same with "/mnt/sdcard/Android/data/" even failed.

Device: Android Q Beta4

fopen("/mnt/sdcard/new.txt","w") fopen("/mnt/sdcard/Android/data/new.txt","w")

We already Refer the storage restriction in Android Developer page for Android Q.

Which path used for store the public information?

Apps cannot store data in arbitrary locations on external or removable storage in Android Q (by default) or Android R (for all apps). The fact that you happen to be using the NDK does not change this.

Your Java code should pass down a valid filesystem path for your NDK code to use (e.g., getExternalFilesDir() on Context).
