The Alien project works fine in my HTC Tattoo (Click) device running CyanogenMod 7. That is Android 2.3.3 without a real GPU.
The window is much bigger than the screen so I cannot see the ship, but it works just fine.
In fact, I could compile and get working some other SDL1.3 code of mine by modifying the Aliens demo.
Great
Have you edited the alien code (not me)?
Can you help me please, why do you think I get ?Texture creation failed? or ?Couldn’t create OpenGL context??
Thank you!From: josebagar

I got it to work without touching the code, only the SDK location and version in local.properties and default.properties.
If it serves of any help, I’m building against Android SDK 10.
From what I can see, the main real difference between your hardware and mine might be that I don’t have a GPU, so I understand that OpenGL is being emulated by software here. Although I’m not sure about “Samsung Galaxy Naos i5800”.
I’ve searched a bit, and maybe initializing OpenGLES in a different way might help?
http://developer.android.com/resources/articles/glsurfaceview.html
Reading through this (http://groups.google.com/group/android-developers/browse_thread/thread/75791c2acbfc7c93/fa2a08c12d3392b5?fwc=1) thread seems to suggest that initializing EGL manually might need additional checks.
PD: Please note that I’m a newbie to both Android coding and OpenGLES, so I might just be plain wrong.
Thank you again
Can you please send me your alien project and the .apk you made?
Then I’ll test it on my phones to see if the problem come from the hardware or the software 
?

The code is far from clean yet. You can get it from here:
http://code.google.com/p/bennugd-monolithic/
It hopefully includes all the required code.
I’ll link the apk when I get home.
You can download the compiled apk from my dropbox folder:
http://dl.dropbox.com/u/3022394/SDLApp-debug.apk
This is a direct recompilation of android-project.zip from the SDL website (ndk-build && ant install).
I managed to run Alien on my Motorola Defy by copying EGLConfigChooser,
BaseConfigChooser, ComponentSizeChooser, SimpleEGLConfigChooser from
android.opengl.GLSurfaceView. I also had to disable OpenGL ES 1 since
SDL kept initializing version 1 after initializing version 2. See diff
in attachment.

The APK from the dropbox link above does nothing on my Galaxy S i9000 running Android 2.2 Froyo.
Yup
It also apply for me. Just a blank screen and then back to home screen.
Running it on HTC wildfire with stock 2.2 .

“Couldn’t set 240x400 video mode: Couldn’t create OpenGL context”
perhaps the emulator can handle any video mode, but the hardware can only handle pre-designed ones?
240x400 is not a common resolution for Android devices. 320x480 and 600x800 are the two most common (320x480 is the most common), I believe.------------------------

I think Sam has stated this a couple of times, but you have to actually copy the game data into your phone’s SD card in order to be able to play the game.
You can do so by configuring adb, downloading the android-project.zip source for the main site and there running the data.sh script.
hank you for your help.
I did the changes suggested in the diff file you sent,
but the program still crash at the SDL Init Video point and says:
glTexImage2D(): GL_INVALID_ENUM
Here is the full source of the .java file (see attached file).
Am I doing something wrong?

If it serves of any help, I’m building against Android SDK 10.From what I can see, the main real difference between your hardware and mine might be that I don’t have a GPU, so I understand that OpenGL is being emulated by software here. Although I’m not sure about “Samsung Galaxy Naos i5800”.
I’ve searched a bit, and maybe initializing OpenGLES in a different way might help?
http://developer.android.com/resources/articles/glsurfaceview.htmlReading through this (http://groups.google.com/group/android-developers/browse_thread/thread/75791c2acbfc7c93/fa2a08c12d3392b5?fwc=1) thread seems to suggest that initializing EGL manually might need additional checks.

I managed to run Alien on my Motorola Defy by copying EGLConfigChooser, BaseConfigChooser, ComponentSizeChooser, SimpleEGLConfigChooser from android.opengl.GLSurfaceView. I also had to disable OpenGL ES 1 since SDL kept initializing version 1 after initializing version 2. See diff in attachment.

If it serves of any help, I’m building against Android SDK 10.From what I can see, the main real difference between your hardware and mine might be that I don’t have a GPU, so I understand that OpenGL is being emulated by software here. Although I’m not sure about “Samsung Galaxy Naos i5800”.
I’ve searched a bit, and maybe initializing OpenGLES in a different way might help?
http://developer.android.com/resources/articles/glsurfaceview.htmlReading through this (http://groups.google.com/group/android-developers/browse_thread/thread/75791c2acbfc7c93/fa2a08c12d3392b5?fwc=1) thread seems to suggest that initializing EGL manually might need additional checks.
PD: Please note that I’m a newbie to both Android coding and OpenGLES, so I might just be plain wrong.
I managed to run Alien on my Motorola Defy by copying EGLConfigChooser, BaseConfigChooser, ComponentSizeChooser, SimpleEGLConfigChooser from android.opengl.GLSurfaceView. I also had to disable OpenGL ES 1 since SDL kept initializing version 1 after initializing version 2. See diff in attachment.
GLSurfaceView.java:

I can compile and run the same program on iPhone,
so the problem is not from the program itself, just the .java file
starting the C++ code.
No idea?
Are you sure your phone supports OpenGL ES 2, since I disabled version 1
in my patch?
Btw, to be able to use WVGA+ resolution in SDL you need to declare
uses-sdk in AndroidManifest.xml, otherwise it will use a lower
resolution to be backward compatible with SDK 1 or something.

Subject: Re: [SDL] Alien android project compile,works on emu but
not on hardw
Thank you for your help.
I did the changes suggested in the diff file you sent,
but the program still crash at the SDL Init Video point and says:
glTexImage2D(): GL_INVALID_ENUM
Here is the full source of the .java file (see attached file).
Am I doing something wrong?
