I wish I could have responded earlier... shame it takes so long to get
a post up.
Anyway, I have had some other C dev environments on my computer so I
removed them and resinstalled cygwin with more components and
everything is working well now.
Take care,

Hi,
Are you running the app by browsing to ndk root directory in cygwin?
open cygwin browse to the ndk root directory. place your project in
apps folder of this root directory.

Re: using opengl es to draw bitmaps

Hi,
That's bad. Is there anything else i can do? In Windows CE i draw in a
bitmap and draw that bitmap to screen. It works very well and fast.
I only want to use official apis.

TARGET_PLATFORM not defined...

I'm going through the steps to install the ndk and attempting to build
the hello-jni example.
I installed cygwin freshly and verified make is version 3.81.
I've ran the build/host-setup.sh which appears to run fine with this
output:
Checking host development environment.

Robert,
thank you for these very helpful instructions, but somehow it does not
completely work for me and the following happens when I try to run the
application after changing the C part of it:
- the .so file is rebuilt
- Java code is compiled
- application is launched somehow picking up the previous version

I don't have access to the rest of the san-angeles at the moment, but
from that code fragment above you should probably be using GL_REPLACE
instead of GL_MODULATE unless you are specifying colors for your
primitives.

Re: Accessing AAC decoder

Which brings up a point that if it is cloned out and utilized in a
native space manner 'on device' ( I am assuming just native and not
NDK compliant) if that than covers royalties, which is likely does not
and then leaves you liable to pay the respective IP holders (VIA
Licensing in the case of AAC).

How to include the Android native code in my native code?

2009-12-16T21:55:07Z

Hi,

I have created my own native classes using Android NDK and I am using
these classes in my Java code to run my application. As I wanted to
use Android audio libraries in native code (Similar to using Android
media APIs in Java dev.) I cloned the media tree from Android open
source.
Can anyone please help me how can I use this with my native code? I

It doesn't look like you're actually using your texture to draw anything...

You'll also need to put OpenGL into ortho mode, set the screen
dimensions, and draw an appropriately-sized poly in the right place so
that it fills the screen.

In general, this doesn't work very well. Trying to upload a full-screen

using opengl es to draw bitmaps

2009-12-16T15:19:54Z

Hi,

I already lost a few hours trying to make this work, but all i'm
getting is a black screen. I'm changing the san-angeles sample to
create a bitmap in RGB form and draw it in screen. This is my code:

GLuint texture;
if (!data || dataLen != width*height)
{
if (data) free(data);

Re: debugging JNI Library loading and UnsatisfiedLinkError Issues

Hi,

This is a very useful information. I am also debugging a similar
issue. I have a JNI call from an Activity and it works fine and I can
display the string that is returned by my JNI code to activity which
then prints on screen. This is the basic hello-jni sample app from
NDK. I have tried to move the System.loadLibrary call to a service
