how to retrieve image from sqlite database in android and display in listview

 Android platform provides several ways to store data in our application. 1. SQLite database 2. SharedPreferences etc For our post, we will only work with SQLite database. First and foremost, we need to understand what an SQLite database is? SQLite database  is an open source SQL database that stores data to a text file on a device. It executes SQL Commands to perform a set of functions, that is, create, read, update and delete operations. On my previous post, I showed how to  store data in SQLite database from edit text, retrieve and populate it in a listview . For this post, I will show the SQLite CRUD operations with images from gallery and text from EditText. We need to understand this; images are stored in SQLite database as BLOB data type. A BLOB is a large binary object that can hold a variable amount of data.  Note, we can only store images in the database as BLOB data type. We need to convert our image path to a bitmap then to bytes. Also
