Solved ! I had not looked carefully at the path on the device, it is not in the sdcard but in the root file system. All is good now.

I’m trying to manage files in my hybrid android app (Cordova).
I installed cordova-plugin-file@6.0.2 and tried to write a file, it doesn’t give me any errors but it doesn’t write anything on the device.
I followed the official directions ( ).
I have used other Cordova plugins and they all work well, for example cordova-plugin-geolocation or cordova-plugin-media-capture. No problems, all right.
Does anyone have any advice to give me or do you know why?
