There are 86 .xml & 136 json files in that folder! do i have to remove from all of them one by one?
Search for "WRITE_EXTERNAL_STORAGE" string, there will only be a few such files.
Also, I can't guarantee that this is the right method. It removes the permissions, but may break something else, test your game thoroughly.
Edit : Also after the "prepare cordova" screen looks likes this...
I don't know.. Try building the app, if there are any serious issues, the build will fail.
After you get the APK, you can open it in Android Studio ("Profile or debug APK") and check the andoid manifest file for those permissions.
