LOCAL_SRC_FILES := FlyIME.apk
LOCAL_CERTIFICATE := PRESIGNED

LOCAL_PREBUILT_JNI_LIBS := \
            lib/libcom_iflytek_inputmethod_contact.so \

            lib/libvadLib-v5.so \
            lib/libvipfont.so

#LOCAL_MULTILIB := 64

include $(BUILD_PREBUILT)

其中lib 目录下的文件可以在安装后通过adb pull出来，放到FlyIME目录下。
