I hear you Mike. I have done this in the past for stuff like PS2 vu
asm code and even with lua. The thing is that the only real choice
that I have seen is to use Eclipse for Android if you want to have
support to debug. My Eclipse Fu isn't strong by any means so maybe I
am wrong.
Can you give a brief overview as to you dev setup?
Sorry, I can't help as I haven't actually wanted to do this. But ant
building is certainly well documented (I use it to do my releases),
and I imagine that googling around for eclipse/android's build mechanism
will probably turn up something (which is optional ultimately). The larger
point is that if you want cpp, it's there and not a criminal act to use.

The Java language specifications do not include a preprocessor syntax,
so we won't. You can use other languages that compile to .class or
.dex though.
What I don't understand is why people who want this don't just
use /usr/bin/cpp in their build process. It's not like it's an
undocumented
API or something.

Filing reasonable feature request (http://b.android.com) with a

Contributing is even better! See the new http://source.android.com
and
be aware that the dev tools development has moved 100% to the
open, so
you can see real time what we're doing.

I think Google should make an effort to improve the android
developer
tools. Here I write some things I think need to take in account:
- Fix problems of communication between IDE and emulators
Yes this is annoying.
- Add support to conditional compilation #IF,#ELSE,#ENDIF (I
wan't to
have 2 versions in the same proyect ... beta and non beta, free and
paid, etc.)
Free and paid apps shouldn't be done by a preprocessor for several
reasons: You want to change the content of XML file. an XML
pre-processor is going to be harder. Also you probably won't have the
same files at all and a pre-processor won't really let you
exclude/include whole files.
We will introduce a new build mechanism that will allow you to easily
share code and resources across 2+ application projects that will be
much better at handling this case.
As for the beta vs. final version, yeah, as someone else said, this
makes no sense.
First the OP didn't talk about using a preprocessor for xml. I
would agree
that that would be odd and there are better tools for that. Still a
preprocessor could be used to conditionally include a resource by
id. How
about I give you some concrete examples and you can help me see the
light?
----------------------------------------
Example 1
----------------------------------------
//#if BETA
if ( hasBetaExpired() )
System.exit( 0 )
//#endif
----------------------------------------
Example 2
----------------------------------------
public final class Assert
{
public static final void RIP( final String msg )
{
//#if BETA
sendReport( msg );
//#endif
System.exit( 0 );
}
}
----------------------------------------
Example 3
----------------------------------------
public class Debug
{
void Println( String msg )
{
//#if !RELEASE
Log.d( TAG, msg );
//#endif
}
}
----------------------------------------
Example 4
----------------------------------------
//#if PLATFORM_BLACKBERRY //@ omega =
(float)MathUtilities.acos( cosom );
//#else omega = (float)java.lang.Math.acos( cosom );
//#endif ----------------------------------------
Example 5
----------------------------------------
public static final float VecToHeading( float x, float y )
{
//#if PLATFORM_BLACKBERRY
//@ float fAngle = ((float)Fixed32.atand2( (int)(x * 65536.0f),
(int)(y * 65536.0f) )) / 65536.0f;
//#else
float fAngle = ((float)Math.atan2( x, y )) *
57.295779513082320876798154814105f;
//#endif
if ( fAngle< 0.0f )
return fAngle + 360.0f;
return fAngle;
}
