Hello.
Ok, my English is not so good, but I'll try my best.
You'll have to set the correct Data and Type. You have to define the
Type by yourself, by getting the
fileextension. Type means the main MIME-type like audio/* or image/*.
For example:
You clicked at the file "MyFavouriteSong.mp3" you have to parse for
the file-extension, here ".mp3".
In the list defined by yourself (maybe in a Textfile or as a resource-
array), you look for that extension
and use the main MIME-type as Type. (should now look like "audio").
If you have the Type, you can call the "setDataAndType" Method with
parameters like
shown in the sample source below.
Android will show you a Dialog with all Application that can handle
the given Type, which did not mean
that the Application can Handle the File by itself. ;-)
*** CODE ***
// Create an Intent
Intent intent = new Intent();
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setAction(android.content.Intent.ACTION_VIEW);
// Category where the App should be searched
String category = new
String("android.intent.category.DEFAULT");
// Setting up the data and the type for the intent
intent.setDataAndType(Uri.fromFile(aDirectory), type+"/
*");
// will start the activtiy found by android or show a
dialog to select one
startActivity(intent);
*** CODE END ***
This is the way i do, but i don't know it's the right one.
Regards,
OC
