java: mraa jni library now dynamically links to libmraa libmraajava.so was statically linking to mraa object files causing duplicate mraa platform instances if a UPM Java module was also loaded. JNI functionality has been moved into src/java/mraajni.c. JVM object is now set when JVM is loaded; see updates to src/java/mraajava.i. This was necessary as the JVM object cannot be directly referenced from mraa as it will not be available when building C/C++ examples.

java: Updated gpio.c to use JNI functions set in mraa_lang_func This is a re-design of commit 0041801. mraa_lang_func_t structure has been added (similar in design to mraa_adv_func_t) that points to JNI functions implemented in src/java/mraajni.c. Functions are set by libmraajava.so, see wrapper entry in src/java/mraajava.i. As gpio.c now uses these functions, language specific #ifdef code has been removed as JNI code is only called if functions are defined (i.e. not NULL) Signed-off-by: Henry Bruce <henry.bruce@intel.com> Signed-off-by: Brendan Le Foll <brendan.le.foll@intel.com> 2016-02-26 13:50:07 -08:00			`* Author: Henry Bruce <henry.bruce@intel.com>`

java: Included jni.h in an external header The reason for this is that applications that use mraa, like upm, need the definitions contained in jni header.
