install_jni_libs.mk revision 966c1e0cae6a59f15264d3b542af08e21e2dc06c 
1# Decides how to install the jni libraries needed by an apk.
2# Input variables:
3#   LOCAL_JNI_SHARED_LIBRARIES
4#   LOCAL_INSTALLED_MODULE
5#   rs_compatibility_jni_libs (from java.mk)
6#   my_module_path (from base_rules.mk)
7#   partition_tag (from base_rules.mk)
8#   my_prebuilt_src_file (from prebuilt_internal.mk)
9#
10# Output variables:
11#   jni_shared_libraries, jni_shared_libraries_abi, if we are going to embed the libraries into the apk;
12#   my_extracted_jni_libs, if we extract jni libs from prebuilt apk.
