docs �� CPU-FEATURES.TXT �� ䷡ ��ִ�.

This NDK provides a small library named "cpufeatures" that can be used at
runtime to detect the target device's CPU family and the optional features
it supports.

�׸�� ؼ��

Usage:
------

The library is available from sources/cpufeatures. It provides an Android.mk
build script that can be used to build it as a static library.

To use it, you must:

* include '$(NDK_ROOT)/sources/cpufeatures/Android.mk' at the start or end of your
Android.mk file.

* add '$(NDK_ROOT)/sources/cpufeatures' to your LOCAL_C_INCLUDES definition.

* add 'cpufeatures' to your LOCAL_STATIC_LIBRARIES definition when building
your final shared library.

your source code can then #include to compile against it.

Here is a simple example:

/jni/Android.mk:
LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE :=
LOCAL_C_INCLUDES += $(NDK_ROOT)/sources/cpufeatures
LOCAL_SRC_FILES :=
LOCAL_STATIC_LIBRARIES += cpufeatures
include $(BUILD_SHARED_LIBRARY)

include $(NDK_ROOT)/sources/cpufeatures/Android.mk

STLport for NDK 1.6
by pelya �� Mon Nov 23, 2009 11:56 am

This is STLport implementation of C++ Standard Template Library, ported to Android 1.6 NDK.
Might help you to port your C++ app to Android.

I'm also porting SDL library, using San-Angeles demo for a basis, not by using /dev/graphics/fb0 as was described in other topics about SDL (which requires root access to run and leaves your phone unusable after exit, unsuitable for Android market hehe).

[mount a file system read-write]

Array

[http://android-tricks.blogspot.com/2009/01/mount-filesystem-read-write.html

Very often when you want to write files to a particular partition on ADP1, you will get a "Permission Denied" if the partition is mounted read-only.
To get around this, you need to mount the partition read-write. Typically this is done with /system partition

[code]
$ adb shell
$ su
$ mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
[/code]

(Replace /dev/block/mtdblock3 & /system with appropriate device path and mount point, as obtained from cat /proc/mounts)
