Users can manage to store the application data like images, audio, videos, and personal contact information by storing them in SQLite Database, in files, or even on a network. Android system allows the content provider to store the application data in several ways. The role of the content provider in the android system is like a central repository in which data of the applications are stored, and it facilitates other applications to securely access and modifies that data based on the user requirements.

Which results in this layout for our Todo app: In particular, we want to add Button, a EditText and a ListView to our Activity in app/src/main/res/layout/activity_main.xml:
Next, we need to define the layout of our views.
Then find Editor -> General -> Auto Import and for Java we need to: On a Mac through Android Studio => Preferences or on Windows with File -> Settings. Creating the Projectįirst, we create a new Android project with minimum SDK 14 named SimpleTodo and then select "Empty Activity". For building this in Eclipse, see this slide presentation. Note: This tutorial is designed for Android Studio and not for Eclipse.
This tutorial is a complementary reference which can be used in conjunction with this Todo app presentation to reference the source code step-by-step.
