Installing wolfJSSE into Android OSP as a System Security Provider
--------------------------------------------------------------------------------

This directory contains a script and support files required when installing
wolfJSSE into an Android OSP (AOSP) source tree as a system security provider.

Files included in this directory:

jsse_install.sh - Script to install wolfSSL and wolfSSL JNI source files into
                  Android AOSP source tree.

wolfssl/ - Directory containing Android.mk and CleanSpec.mk files to be placed
           in "<android_aosp>/external/wolfssl" directory. Used by
           jsse_install.sh

wolfssljni/ - Directory containing Android.mk file to be placed in
              <android_aosp>/external/wolfssljni" directory. Used by
              jsse_install.sh

For instructions on installing wolfJSSE as a Android security provider, please
reference the document titled:

Printing Debug Messages to Android adb logcat
--------------------------------------------------------------------------------

By default, the wolfJSSE debug logging mechanism prints debug messages using
System.out.println(). If you would rather use the android logging API, a few
minor changes can be made to the wolfJSSE source and Android.mk build file:

1. Changes to <wolfssljni>/src/java/com/wolfssl/provider/jse/WolfSSLDebug.java

    a) Add an import for "import android.util.Log"
    b) Add a static TAG variable to be used with the Log.*() methods, ex:

       public class WolfSSLDebug {
           private static final String TAG = "WolfJSSE";
           ...
       }

    c) Change the print line in WolfSSLDebug.log() to call one of the Android
       log methods. For example, if using the info method:

       public static void log(Class cl, String tag, String string) {
           if (DEBUG) {
               Log.i(TAG, tag + " : " + cl.getSimpleName() + " : " + string);
           }
       }

2. Changes to <wolfssljni>/platform/android_aosp/wolfssljn/Android.mk

    a) Add "-llog" to LOCAL_LDFLAGS
    b) Add "liblog" to LOCAL_SHARED_LIBRARIES

    For example (Android.mk):

        # Create wolfSSL JNI native library
        ...
        LOCAL_LDFLAGS := -llog
        LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/native
        LOCAL_SHARED_LIBRARIES := libwolfssl liblog
        ...
        include $(BUILD_SHARED_LIBRARY)
