I have developed an app that works up to Android 9 and with Android 10 it doesn't. The app should wait for a new file to be created in a specific folder and then perform some actions, my main suspect is FileObserver because with the API 29 it tells me that the constructor FIleObserver (String path) is deprecated. Using the suggested FileObserver (File file), introduced with the API 29, when I launch the application I get this error:

java.lang.NoSuchMethodError: No direct method (Ljava / io / File; I) V in class Landroid / os / FileObserver; or its super classes (declaration of 'android.os.FileObserver' appears in /system/framework/framework.jar!classes2.dex)

would anyone know how to help me?

Have you worked it out? – MRamzan Aug 10 '20 at 11:47
Yes thanks, i added the option for using legacy authorization in accessing memory. – Francesco Aug 11 '20 at 12:11
@Francesco, Could you show your code, which uses FileObserver to watching for change in a directory in android 10? – user2905416 Nov 04 '20 at 08:35
I'm sorry but i have not anymore the code. However i remember i simply added the option for using legacy authorization in accessing memory – Francesco Nov 11 '20 at 08:35
