In order to create our DataBaseHandler we will extend SQLiteOpenHelperandroid SDK class. Implementing DataBaseHandler classįor sqlite integration purpose we will create a DataBaseHandler class in our application class.
#ANDROID SQLITE COMMANDS ANDROID#
If you’ll put a breakpoint in the onCreate() method and lunch your android program, you will see that the first thing that is called as your program process is launched, is the creation of your application class. In our case we will crate DataBaseHandler in the application class once, and afterwards we will access it from any activity in our program.įirst, we need to create our base class which extends SDK application class, we will call it DyncamicSqliteApplication: After declaring application class in your AnadroidManifest.xml it will be instantiated when the process of your application/package is created.ĭeclaring your custom application class is necessary when you want to keep instances through all your process life time.

You can determine given class even if you don’t know its formation at compile time. Since Reflection happens in the runtime, it makes your code very flexible and dynamic. Reflection is a language ability that gives you the capability to inspect and dynamically call classes, methods, attributes etc, on specific objects based on their structure without knowing them in advance. Basic understanding in android application structure.ģ. In the following article I will make an example of management and implementation of Sqlite database on android platform by using reflection of the Java classes. Inserting TEST class values to sqlite TEST table.
