Method Detail

init

static void init()
          throws java.lang.UnsatisfiedLinkError

Attempts to load the shared JNI library. First try loading the platform-specific library name (e.g. conscrypt_openjdk_jni-linux-x86_64). If that doesn't work, try to load the library via just the prefix (e.g. conscrypt_openjdk_jni). If not found, try the static library name. The non-suffixed dynamic library name is used by the Android build system, which builds the appropriate library for the system it's being run on under that name. The static library name is needed in order to support Java 8 static linking (http://openjdk.java.net/jeps/178), where the library name is used to invoke a library-specific load method (i.e. JNI_OnLoad_conscrypt).

Throws:

java.lang.UnsatisfiedLinkError - if the library failed to load.
