Finally, remember to add permissions

<!--Create and delete files in SDcard permissions--
<uses-permission android:name= "Android.permission.MOUNT_UNMOUNT_FILESYSTEMS"/>
<!--write data to sdcard permissions--
<uses-permission android:name= "Android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-feature android:name = "Android.hardware.camera"/>
<uses-feature android:name = "Android.hardware.camera.autofocus"/>
