Android intent/filters

An Android  Intent  is an abstract description of an operation to be performed. It can be used with  startActivity  to launch an Activity,  broadcastIntent  to send it to any interested BroadcastReceiver components, and  startService(Intent)  or  bindService(Intent, ServiceConnection, int)  to communicate with a background Service. The intent itself, an Intent object, is a passive data structure holding an abstract description of an operation to be performed. For example, let's assume that you have an Activity that needs to launch an email client and sends an email using your Android device. For this purpose, your Activity would send an ACTION_SEND along with appropriate  chooser , to the Android Intent Resolver. The specified chooser gives the proper interface for the user to pick how to send your email data. Intent email = new Intent ( Intent .

Android Content Provider(Easy explaination with diagram)

Image
A content provider component supplies data from one application to others on request. Such requests are handled by the methods of the ContentResolver class. A content provider can use different ways to store its data and the data can be stored in a database, in files, or even over a network. Content providers let you centralize content in one place and have many different applications access it as needed. A content provider behaves very much like a database where you can query it, edit its content, as well as add or delete content using insert(), update(), delete(), and query() methods. In most cases this data is stored in an  SQlite  database. A content provider is implemented as a subclass of  ContentProvider  class and must implement a standard set of APIs that enable other applications to perform transactions. Create Content Provider This involves number of simple steps to create your own content provider. First of all you need to create a Content P...
