Eclipse project build settings

in Android Processing • 3 years ago

Eclipse android-core project from Subversion looks just fine, but just unsure how to set up the Java Build Path.

ANDROID_LIB is of course an unbound classpath variable by default, looking for the SDK. I'm guessing I want to go to Project Properties > Java Build Path > Libraries > ANDROID_LIB > Source attachment > Edit and choose a class variable. Then added ANDROID_LIB, pointing at the root directory for my SDK install (which for me is /home/peter/dev-tools/android-sdk-linux-x86/)

That re-builds and appears to restore ANDROID_LIB, but...

For some reason, seems here on Linux I'm not finding java.lang.Object, just for this project, within processing.xml... not sure why that'd be.

Thanks for the help; I know this isn't an officially-supported procedure, but it's always this basic stuff that gets me hung up in Eclipse; I'm fine once I've got it going, so appreciate the input. ;)

Just looking at the .classpath file. So it has the ANDROID_LIB sourcepath; did I inadvertently then point to that but *not* the JDT for Java?

Since the checked-out copy of android-core can't seem to find the JDT (yay, Eclipse!), I instead:

1. Create a new Android project, targeting 2.1. Uncheck Create an Activity.

2. Set the project (Properties > Android) to a Library using the "is a Library" checkbox.

3. *Manually* copy and paste the src folder from the checked out version into the Library.

4. Use the new library as the dependent project rather than the checked out version.

And yes, I'm aware that this clunkiness is part of the reason to use the PDE and not Eclipse, but if you have a workspace full of Android projects, etc., a little clunkiness isn't a deal-breaker if it all gets working. I'll keep at it.

Thanks to Peter Brinkmann for suggesting we try the brute-force method.

Is there something I should use as reference for how best to structure the Activity that calls on Processing's View?

(otherwise, I'm going to consider this question answered)

iirc, you just check out android-core as a vanilla java project, that uses ANDROID_LIB as its lib. no additional android tooling. set ANDROID_LIB in your workspace preferences.

then when making new android projects (new project -> android..), just make sure that android-core is listed as one of the projects on the build path.

i've done this with several projects, but it's been a little while so i don't recall the *exact* sequence of things.

Oh, wait, maybe I was trying to set ANDROID_LIB as a project variable and not a workspace variable. And point ANDROID_LIB to... what, the root directory of the Android SDK? (or /tools?)

It points to the .jar file. Mine, f'rinstance is set to: /opt/android/platforms/android-2.1/android.jar

set using: Preferences -> Java -> Build Path -> Classpath Variables -> [ New... ]

Ah, okay -- got it. That makes sense. Let me give that a try.
