If the users install my app outside the playstore, there will not be futures problems if I leave as it is now in Kodular? at least until there is a correct solution implemented.
Edit: I tried what you just told me declaring in manifiest “READ_MEDIA_IMAGES” and now it ask me correctly when I open the app the permission, and the draw is being saved correctly in the files (I´m using the Canvas “Save as” option), but is not showing the image in the app (I use the File tools to see if image exist and Dynamic component to update them).
And the error message appears anyway “ERROR 908: READ_EXTERNAL_STORAGE”
