I am trying to use camera and save image. Followed the steps as commonsware suggested. Constantly I am getting error -

2018-11-12 02:10:54.588 3145-3173/com.bisw.weac E/DatabaseUtils: Writing exception to parcel
java.lang.SecurityException: Permission Denial: writing android.support.v4.content.FileProvider uri content://com.bisw.weac.provider/external_files/Android/data/com.bisw.weac/files/wallpaper/theme.jpg from pid=5566, uid=10071 requires the provider be exported, or grantUriPermission()

I have tried almost everything like - intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION); but nothing helps. I am croping the image from camera.
