Intent.ACTION_SEND - Create an Intent to Send Data from an Activity

ACTION_SEND was added in API Level 1
public static final String ACTION_SEND
indicates that the intent is sending data from one activity to another, even across process boundaries.
Activity Action: Deliver some data to someone else. Who the data is being delivered to is not specified; it is up to the receiver of this action to ask the user where the data should be sent.

When launching a SEND intent, you should usually wrap it in a chooser (through createChooser(Intent, CharSequence)), which will give the proper interface for the user to pick how to send your data and allow you to specify a prompt indicating what they are doing.

Input: getType() is the MIME type of the data being sent. get*Extra can have either a EXTRA_TEXT or EXTRA_STREAM field, containing the data to be sent. If using EXTRA_TEXT, the MIME type should be "text/plain"; otherwise it should be the MIME type of the data in EXTRA_STREAM. Use */* if the MIME type is unknown (this will only allow senders that can handle generic data streams). If using EXTRA_TEXT, you can also optionally supply EXTRA_HTML_TEXT for clients to retrieve your text with HTML formatting.
Optional standard extras, which may be interpreted by some recipients as appropriate, are: EXTRA_EMAIL, EXTRA_CC,EXTRA_BCC, EXTRA_SUBJECT.
Output: nothing. Constant Value: "android.intent.action.SEND"
