Question

I realize even I do not have

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />  

in my `AndroidManifest.xml

String path = Images.Media.insertImage(((Activity)MainView.this.getContext()).getContentResolver(), screenCaptureBitmap, "Title", "Description");

still able to write image file to location /mnt/sdcard/DCIM/Camera. May I know why is it so?

Answer 1

maybe in depend on the content provider MediaStore, you through it to insert, it’s a RPC invoke. and the MediaStore provider in source code: packages/providers/MediaProvider, in it’s manifest define the permission

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />,

may be it’s the reason.
