<p class="note"><strong>Note:</strong> The constants {@link
android.content.Context#MODE_WORLD_READABLE} and {@link
android.content.Context#MODE_WORLD_WRITEABLE} have been deprecated since API level 17. Since
API level 24 their use will result in a {@link java.lang.SecurityException} to be thrown.
This means that apps targeting API level 24 and higher
cannot share private files by name, and attempts to share a "file://" URI will result in a
{@link android.os.FileUriExposedException} to be thrown. If your app needs to share private
files with other apps, it may use a {@link android.support.v4.content.FileProvider} with
the {@link android.content.Intent.FLAG_GRANT_READ_URI_PERMISSION}.

<p class="note">
<strong>Note:</strong> Before API level 24, internal files could be made accessible to other
apps by means of relaxing file system permissions. This is no longer the case. If you wish
to make the content of a private file accessible to other apps, your app may use the
{@link android.support.v4.content.FileProvider}. See <a
