Can you please send your mails as plain text ? 
The below is totally unreadable in my text-based mail client :(

Hello,

It seems Android 6.0 forces usage of PIC-enabled shared libraries only.
Currently the Android FPC target is not PIC compatible, since the 
startup assembler code is needed to be converted to PIC.


You need to use targetSdkVersion <= 22 until PIC is fixed for the 
Android target.

  2.1  targetSdkVersion <= 22
   All Works

  2.2. targetSDKVersion = 23
