I have purchased Basic4Android in August 2009.I have developed so many application till September 2011.
But now some of the library is not working (HttpClient and PdfViewer Library).For this I have post my problem in Forum,but as per Forum discussion need to upgrade 6+ version instead of 2.30.My question why this old library is not working now ????
Old libraries will still work with old versions of B4A.
New libraries might not work as they rely on features not available in older versions of B4A. There were many changes since B4A v2.30 in both Android and B4A.
It's like "I have WIN95 and want to run WIN10 apps"...
Just buy the newest version of B4A... (I recommend the Enterprise version with 2 years of free upgrade for 119US$). Even the standard version for 59US$ does it (same version but only 2 months of free upgrade).
