Android - Correct usage of Cursor

I've seen many Android source code examples on how to loop through a Cursor and most of them are unnecessarily complicated or perform unnecessary operations.

Sincerely, I don't know why people overcomplicate it. Cursor usage is pretty simple and similar to JDBC's ResultSet. The general code skeleton is as follows:

Cursor c = null; 
try {
    c = ... // Get the Cursor from SQLite DB
    while (c.moveToNext()) {
        // Perform operations with current row data
} finally {
    if (c != null) {

There's no need to check if Cursor instance is null (Android API never returns a null Cursor) or moving to first (moveToFirst()) and do/while because returned Cursors are always positioned before first element. And don't forget to close the Cursor on a finally to ensure it is closed even if an exception is thrown (to avoid memory leaks).
