[LIB] [B4A SourceCode] ahaShareLibrary

Hi!

As we all have the Problems with sharing Text/Pictures via Intents and Facebook, I decided to write a small library that get rid of this Problem. It's very easy to use and takes all the work away from you

You can share Text, Pictures, Documents.....

It's still beta, so please report any Bugs/Wishes.

Usage is very simple:

B4X:

Dim Share as ahaShare
Share.initialize(Me, "Share")
Share.FaceBookAppID = "xxxx"
Share.FaceBookRedirectUri = "http://www.xxxxxx.xxx/"
Share.Share("Test-Subject","Test-Text")

After sharing, the Finished Event is called

B4X:

Sub Share_Finished
   ..your code here
End Sub

Screenshot :

PS: As you can see you can customize nearly everything:

This library is written in B4A

I hope you like it

ahaShare
Methods:

IsInitialized As Boolean
Tests whether the object has been initialized.

Addfile (Directory As String, Filename As String) As String
Adds a file to the Intent
Attention: file.DirAssets and file.dirInternal will NOT> work as Directory!!

Addpackagefilter (PackageFilter As String) As String
Adds a packagefilter. Packages with the given names will not be shown in the ContentChooser
Example1: "com.google.android.keep" to hide Google Keep from the choosable Apps
Example2: "synology" hides every Synology-App

Clearfiles As String
Clears all added files

Initialize (Module As Object, EventName As String) As String

Normal Library usage:
-----------------------
<code>Dim Share as ahaShare
Share.initialize(me, "Share")
Share.FaceBookAppID = "xxxx"
Share.FaceBookRedirectUri = "http://www.xxxxxx.xxx/"
Share.Share("Test-Subject","Test-Text")</code>

Event Finished will be raised when Sharing is finished:
Sub Share_Finished
..your code here (i.e deleting temp files,...)
End Sub
