Android A to Z

Here i am going to describe all the basic to advanced android experience I have learned …I have nfolowed and mainly…Sharing is carin..By sharing here it will be clear to mine also 🙂


Application Component

Activities -Dictate the UI and handle the user interaction
Services-The background processing associated with application
Boradcast Receivers – They handle communication between android os and applications
Content Providers – The handle data and database management issues

Activiity can implemented as subclass of activity as follows:

public class MainActivity extends Activity{


Services can be implemented as follows:
A service is implemented as a subclass of service class as follows:

public class MyService extends Service{


Broadcast receiver is implemeted like this:
Broadcast receiver is implemented as Broadcast receiver class and each message is broadcasted as an intent object

public class MyReceiverNew extends BroadcastReceiver{

Content Providers requests is handled by the methods of ContentResolver class

public class MyContentProvider extends ContentProvider{


There are some additional components
Fragments-behaviour of UI in an activity
Views – UI elements that are drawn onscreen including buttons, lists, forms etc.
Layout – View hierarchies that control screen format and appearance of the views

Intents – Message wiring components together

Resources – External elements, such as strings, constants and drawable pictures.

Manifest – Configuration file for the application

Need to Finish this  Chapter from  -> Android Resource

-Need to complete the basic android chapters to Advanced topics
– then Need to read some tutorials like Android Navigation and SQL Database from tutorialspoint.
– But first of all need to clear all the basics of java OOP

করে করে এগোতে হবে…সেটা না পারলে দেখে দেখে বুঝে নিয়ে এগোতে হবে পরে সময় পেলে আবার করে করে এগোতে হবে কিন্তু বসে থাকা যাবে না কনফিডেন্স গ্রো করতে হলে অনুশীলন বা চর্চার কোনো বিকল্প নাই।

It would be a great help, if you support by sharing :)
