use of com.android.documentsui.model.DocumentInfo in project android_frameworks_base by ResurrectionRemix.

the class DirectoryFragment method deleteDocuments.

private void deleteDocuments(final Selection selected) {
    Metrics.logUserAction(getContext(), Metrics.USER_ACTION_DELETE);

    // This "insta-hides" files that are being deleted, because
    // the delete operation may be not execute immediately (it
    // may be queued up on the FileOperationService.)
    // To hide the files locally, we call the hide method on the adapter
    // ...which a live object...cannot be parceled.
    // For that reason, for now, we implement this dialog NOT
    // as a fragment (which can survive rotation and have its own state),
    // but as a simple runtime dialog. So rotating a device with an
    // active delete dialog...results in that dialog disappearing.
    // We can do better, but don't have cycles for it now.
