How to launch Android Calendar application using Intent (Froyo)

Question

I want to open up the Calendar application from an android application. When i searched online, all i got is to create new events using intent. I could find Intents to open

Answer 1

Using intents to view calendar data

Calender Provider offers two different ways to use the VIEW Intent:

To open the Calendar to a particular date.
To view an event.

add permissions to manifest

Here is an example that shows how to open the Calendar to a particular date:

 // A date-time specified in milliseconds since the epoch. 
 long startMillis;
 ...
 Uri.Builder builder = CalendarContract.CONTENT_URI.buildUpon();   
 builder.appendPath("time");
 ContentUris.appendId(builder, startMillis);
 Intent intent = new Intent(Intent.ACTION_VIEW)
     .setData(builder.build());
   startActivity(intent);

Here is an example that shows how to open an event for viewing:

long eventID = 208;
...
Uri uri = ContentUris.withAppendedId(Events.CONTENT_URI, eventID);
Intent intent = new Intent(Intent.ACTION_VIEW)
   .setData(uri);

    startActivity(intent);

Is it possible to launch the Calendar to a specific week or day?

So, now it is possible, but requires min API 14.
