hello, Matthew!

how can I help you today?

Hi Mark, pleased to meet you

yes i've a problem where i'm creating an Android project that has a project library in it. i have declared the library as 'is library' and in the main app i have added it as a library

the problem is the library apk cannot be found

when i run the app

there is no library APK

an Android library project does not generate an APK

your main application project generates an APK

Another problem i have noticed is a classCastexception on the application object

in the library i have extended the Application object, i want to use this appObj in the main Application, but i get this exception

does your manifest in the main application indicate that it should use this library's class?

:)no... i've declared activities and services from the library in the main Application's Manifest... but no there is no <uses> library

that is not what I mean

there is not supposed to be a <uses-library>

however, a custom Application subclass is not going to be used magically

your <application> element needs the android:name attribute

where the value is the fully-qualified class name of your custom Application subclass

So if my library Application class has been extened and given the name ApplicationObj, i need to specify this name in the the main applications <Aplication> Tag?

yes

ok i'll give it a whirl? How long are you are for... i'm uk time

around for, i meant

the chat is scheduled to run for another 22 minutes

ok cheers

no there is still a problem. In the console window eclipse is saying couldn't find library apk

hello, Susheel!

Hi Mark, whenever you are ready I have only one question for you

Matthew: perhaps you are trying to run your library

Susheel: go ahead

I have a custom view. I drew a rectangle on canvas. Is it possible to make the view listen to touch events?

if so how?

override onTouchEvent() and do whatever you need to

i can post you the logcat statements. sorry but i've just joined your site, can i post them here or would you prefer a SO question and i'll bump from your site?

Ok. Great. Thanks Mark! Have a good day :)

i'm running the main application (MainActivity)is in there.

Matthew: then there is a problem with your Eclipse configuration

again, there is no library APK to be run

or perhaps https://stackoverflow.com/a/13448679/115145

ok removed the library as a project dependency. the apk problem has gone, but there is a ClassNotFound exception regarding the Application Object

class not on path it says

that's because you removed the library project

go to Project > Properties, click on the Android item in the list

then click the Add button next to the Libraries list, find your library, click OK

it will now appear in the list

click OK to close the properties dialog

do all that for the main project

the main project itself should not be a library ("Is Library" unchecked)

at this point, run the main project

you can read more about how to define and connect library projects at https://developer.android.com/tools/projects/pr... and in the book

if you wind up back at the same error as before, then there may be an issue with the run configurations of your main project

and that's a wrap for today's office hours chat

the transcript will be archived at http://commonsware.com/office-hours/ shortly

ok thanks Mark

the next chat is Tuesday, 10am US Eastern Time

have a pleasant evening!

cheers, you too
