Examples with UriPermission android.content.UriPermission used on opensource projects

Example 1 with UriPermission

use of android.content.UriPermission in project muzei by romannurik.

the class GalleryProvider method deleteChosenPhotos.

private int deleteChosenPhotos(@NonNull final Uri uri, final String selection, final String[] selectionArgs) {
    // Opens the database object in "write" mode.
    final SQLiteDatabase db = databaseHelper.getWritableDatabase();
    // We can't just simply delete the rows as that won't free up the space occupied by the
    // chosen image files for each row being deleted. Instead we have to query
    // and manually delete each chosen image file
    String[] projection = new String[] { GalleryContract.ChosenPhotos.COLUMN_NAME_URI };
    Cursor rowsToDelete = queryChosenPhotos(uri, projection, selection, selectionArgs, null);
    if (rowsToDelete == null) {
        return 0;
    }
    rowsToDelete.moveToFirst();
    while (!rowsToDelete.isAfterLast()) {
        String imageUri = rowsToDelete.getString(0);
        File file = getCacheFileForUri(getContext(), imageUri);
        if (file != null && file.exists()) {
            if (!file.delete()) {

    String finalSelection = selection;

    }
    int count = db.delete(GalleryContract.ChosenPhotos.TABLE_NAME, finalSelection, selectionArgs);

        notifyChange(uri);
