[android-developers] How to load resources like texture images & sound files in native code?
Dear Friends, I am trying to load resources(e.g. texture images, sound files) in my native .CPP file. As I have to use the resources like texture images in native code, this why I am looking for any method to add them in my native code itself. Is this possible to add resources in my JAVA file and access these resources in my native code? If yes then how? Please guide me.

Dear Stephen, I am new to Android Development through native code. As per your directions, I followed the example http://lol.zoy.org/blog/2011/3/2/load-pngs-using-android-ndk Unfortunately, I am not able to fully understand it. I am bit confused about its integration with actual code. Plz help.

[android-developers] Re: System.loadLibrary() failes in Android with UnsatisfiedLinkError
I recommend you to install cygwin along with Android NDK. Compile your
native code using cygwin, refresh your project in Project Explorer
then run the activity.

[android-developers] Getting started with Android NDK
Hi,
I have to use NDK for porting of my C/C++ code into ANDROID Game.
Now that I am having problem to start with NDK.
I have downloaded the NDK-r5b from developer.android.com
But now, I am not even able to run the Hello-jni program provided
within NDK samples.
I have installed CYGWIN
When i run:
$ cd /cygdrive/c/android/android-ndk-r5b/samples/hello-jni
$ ndk-build
I get an ERROR: You are using a non-Cygwin compatible Make program.
I tried installing GNUMake 3.81 but the problem persist.
**
I tried to run HELLO-JNI sample program of NDK through Eclipse IDE
There is force close on the Android AVD.
& logcat was showing exception like below -

[android-developers] Best way to convert iPhone 3-D game code to run on Android devices?
Dear Friends, I need to convert our existing iPhone 3-D action game code to run on Android. Recently, I have developed 2-D game on Android platform and now I am moving towards 3-D. These days I am exploring the options to convert iPhone/iPad & Symbian code to run on Android devices. Should I write the entire code of iPhone 3-D game(previously written in Objective C using OpenGL ES) from scratch in Java using OpenGL apis, once again? I have also successfully installed and studied samples of Android NDK(specially San Angles sample code) as well. I am also looking for 3- D game using OpenGL example in Android as well. Is the use of Android NDK is recommended in order to convert iPhone code on Android platform or I should code in Java? I am looking forward for piece of suggestions from your side. Thanks in advance.
