Tips to import sample Android projects to Eclipse

I am a newbie to Eclipse and Android applications development. I installed the Eclipse yesterday and tried to take a look at the Android sample to start with. I had problems to import sample project into Eclipse. Google is always the one I first tried. I found this article: How to import sample Android projects to Eclipse. It is helpful to me. I think it will also be helpful to others.

Here is the tips: Simply create project from existing source (then use "Browse" to select sample shipped with SDK).

struct ipv6_mreq has no member named ipv6mr_interface

When I am porting ffmpeg to Google Android, I got an error: 'struct ipv6_mreq' has no member named 'ipv6mr_interface'. I dont understand what happened. When I google the related information, I got this article: Linux kernel headers violate RFC2553. The corresponding header file is bionic/libc/kernel/common/linux/in6.h. I have to correct the usage of ipv6_mreq.ipv6mr_interface into ipv6_mreq.ipv6mr_ifindex.
What I am concern is does Bionic libc use the ipv6_mreq structure in a correct way?

Android build system

Found document in android open source. They are in myandroid/development/pdk/docs/. Following information are from the "Android build system" section. It is more helpful than "Add a new component into open source Android".
A makefile defines how to build a particular application. Makefiles typically include all of the following elements:

1. Name: Give your build a name (LOCAL_MODULE := ).
2. Local Variables: Clear local variables with CLEAR_VARS (include $(CLEAR_VARS)).
3. Files: Determine which files your application depends upon (LOCAL_SRC_FILES := main.c).
4. Tags: Define tags, as necessary (LOCAL_MODULE_TAGS := eng development).
5. Libraries: Define whether your application links with other libraries (LOCAL_SHARED_LIBRARIES := cutils).
6. Template file: Include a template file to define underlining make tools for a particular target (include $(BUILD_EXECUTABLE)).

The following snippet illustrates a typical makefile.

LOCAL_PATH := $(my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE :=
LOCAL_SRC_FILES := main.c
LOCAL_MODULE_TAGS := eng development
LOCAL_SHARED_LIBRARIES := cutils
include $(BUILD_EXECUTABLE)
(HOST_)EXECUTABLE, (HOST_)JAVA_LIBRARY, (HOST_)PREBUILT, (HOST_)SHARED_LIBRARY,
(HOST_)STATIC_LIBRARY, PACKAGE, JAVADOC, RAW_EXECUTABLE, RAW_STATIC_LIBRARY,
COPY_HEADERS, KEY_CHAR_MAP

Good start to port 3-party to Android

After you have the open source Android, look into folder external/openssl/README.android. It is a good start to port application to Android.
