wish helps you There are some errors and notices in your script output and you have the xdebug extension which is trying to make them look pretty by wrapping them in HTML.

How to store username and password details from my app to my database and how to connect my app with my database?
it helps some times You can refer to the sqlite database tutorials to store the data into the database. If you are storing the data in the database that is in the server, then also see the tutorials on connecting to the server database using any volley or retrofit etc. Always its better dont store password in the text format, hash it with the hashing algorithm like SHA256, MD5 etc and then store it.
