LogCat where my SQLite statement is red but the app runs fine

I am making an android app where there is a basic login function. I already created the accounts. It logins successfully but I am bothered by an error (don't know why it's an error if it works fine). This shows red:

E/DatabaseHelper(20507): SELECT * FROM users WHERE u_name = 'admin' AND u_password = '21232f297a57a5a743894a0e4a801fc3'

Here's the code from the DatabaseHelper

public UserModel getUser(String user_name, String user_password) {
    SQLiteDatabase db = this.getReadableDatabase();

    String selectQuery = "SELECT * FROM " + TABLE_USER + " WHERE "
            + KEY_USERNAME + " = '" + user_name + "' AND " + KEY_PASSWORD + " = '" + user_password + "'";

    Log.e(LOG, selectQuery);

    Cursor c = db.rawQuery(selectQuery, null);

    if (c != null)
        c.moveToFirst();

    UserModel ur = new UserModel();
    ur.setId(c.getInt(c.getColumnIndex(KEY_ID)));
    ur.setUname((c.getString(c.getColumnIndex(KEY_USERNAME))));
    ur.setPassword(c.getString(c.getColumnIndex(KEY_PASSWORD)));
    ur.setPrivilege(c.getString(c.getColumnIndex(KEY_PRIVILEGE)));

    return ur;
}

And here's the call:

UserModel user = new UserModel();
user = db.getUser(username, pw);
