Here's an example which builds the "?, ?, ?, ..." placeholder string with StringBuilder. If there are many parameters, plain string concatenation would create lots of garbage, StringBuilder helps with that.

String[] ids = {"0", "1", "2", "3",...};

StringBuilder placeholders = new StringBuilder();
for (int i = 0; i < ids.length; i++) {
    if (i != 0)
        placeholders.append(", ");

    placeholders.append("?");
}

String where = "id IN (" + placeholders.toString() + ")";

db.delete("rows", where, args);
