Android mode starts ok (using latest code from svn, on ubuntu 9.04). But
when hitting the run button I get (for any sketch):

taskdef class com.android.ant.SetupTask cannot be found

The android emulator starts, but doesnt seem to show any processing-related
sketch. The console dump is the following:

emulator -avd Processing-Donut -port 5566 -no-boot-anim

have you removed the work folder and done ./make.sh again since the recent
updates?

mmm.... I updated to the latest revision in the svn, deleted linux/work and
did ./make.sh again.

But the problem persists:

/home/andres/Devel/Processing/svn/trunk/build/linux/work/examples/Basics/Color/Brightness/android/build.xml:15:
taskdef class com.android.ant.SetupTask cannot be found

There is also the exception:

Not sure if both are related.

Could the "com.android.ant.SetupTask cannot be found" error happen because
an installation problem (some component from the android sdk missing)?
Right now I'm checking if I have all the required components installed...

it means that ant-launcher.jar isn't being found (or maybe ant.jar, but i
think it's ant-launcher.jar). trying to find out why it's not being copied now.

huh, i'm not getting the SetupTask issue, though i'm seeing a problem with
it not being able to find processing.android.core, which i need to fix.
i'll keep looking into it.

Oh! I missed that this was the /android/ SetupTask that was missing. Right,
so that's an improperly installed SDK. What parts of the SDK have you
installed? Did you follow the full instructions?

I'm using the latest android SDK for linux (android-sdk_r04-linux_86), with
the following packages installed:

* Android SDK Tools, revision 4
* SDK Platform Android 1.6, API 4, revision 2
* SDK Platform Android 2.0, API 5, revision 1
* Google APIs by Google Inc., Android API 4, revision 2
* Google APIs by Google Inc., Android API 5, revision 1

I followed the installation steps listed in
http://developer.android.com/sdk/index.html, with the exception of #2
(installation of ADT plugin for Eclipse). I didn't try the Hello World
example for Eclipse either, but I'll do this next, to make sure that the
SDK is working fine from Eclipse.

that's really odd. have you set ANDROID_SDK in your .bashrc or .profile?
and have you added to the tools to your PATH? (you shouldn't need to, but...)

Ok, I was aware of the "export PATH=blahblah" in the .bashrc file (read it
in the android installation guide), but not of exporting the ANDROID_SDK
environmental variable, which I just did...

However, still getting this "com.android.ant.SetupTask not found" error.
Weird... I'll do some testing from Eclipse and update soon...

right, you shouldn't need to set either, since Processing will take care of
them, but i'm trying to figure out why it's not finding those libraries.

i tried the install on a clean ubuntu 9.10 install and it was ok, just
using the instructions. not sure what's going on yet.

well, in that case I can do an update to 9.10 as a last resort...

oh no, i definitely wouldn't do that! i only meant that as background (i
doubt it has anything to do with that). i assume it works on 8.04 too.
don't install 9.10 on a working system. ;-)

Indeed, upgrading (or doing a fresh install for that matter) would be a
very, very last measure.

My 9.04 system is working quite nicely in fact.

:-)

Ok, I think found something. For any sketch that I try to run in Android
mode, a bunch of files are generated in the corresponding sketch folder in
work/linux/examples. Among them:

AndroidManifest.xml
Build.properties
build.xml
local.properties
...etc

build.xml is the one referencing to com.android.ant.SetupTask:

<?xml version="1.0" encoding="utf-8"?>
<project name="Brightness" default="help">
<property file="local.properties"/>
<property file="build.properties"/>
<property file="default.properties"/>
<path id="android.antlibs">
<pathelement path="${sdk-location}/tools/lib/anttasks.jar" />
<pathelement path="${sdk-location}/tools/lib/sdklib.jar" />
<pathelement path="${sdk-location}/tools/lib/androidprefs.jar" />
<pathelement path="${sdk-location}/tools/lib/apkbuilder.jar" />
<pathelement path="${sdk-location}/tools/lib/jarutils.jar" />
</path>
<taskdef name="setup"
classname="com.android.ant.SetupTask"
classpathref="android.antlibs" />
<setup />
</project>

Now, the variable sdk-location seems to be defined in local.properties,
where it has the (wrong) value:

sdk-location=/opt/android

I modify this value by hand so sdk-location points to the right path, but
when I re-run the sketch, the file gets automatically rewritten with the
wrong value.

What I did next was to create the symbolic link /opt/android pointing to
the correct path for the android-sdk in my system, and then voila!, the
"com.android.ant.SetupTask not found" error went away and the compilation
process proceeded. New error shows up (package processing.android.core does
not exist) but I think the problem seems to be with this wrong path
assignment for the android sdk in /opt. I don't know where is it coming
from, since I set up all the environmental variables to the right location.

ah! good catch. that's why it was working on mine--i always use
/opt/android no matter what platform. the error comes from really early
code that i was using before i had made the sdk location work properly.
that's now fixed in svn, but i need to fix one more issue with the core.zip
file for android before you'll be able to build properly.

this issue is now all set, give 0174 a shot and also w/ the svn. if you run
into new problems use a new bug, since the one here has been fixed.
