Referencing Android custom library cause runtime class not found error in Application

Question

I am working on a custom Android library. I start off with a java project (in Eclipse) with another UI testing Android project.

In my UI testing project, I reference the library project in build path, and everything is good and I can test the library codes in the UI.

Later on, I decided I need to have the 'Gen' code (for custom styles attributes), so I try to change my library to an Android project (via Android-tools -> convert.. ), and disasters happens! After fixing up all the compile time problems, it finally 'let' me start the UI testing application, and bangs! When I try to create any objects from the library class, it said (in the Log) that Class not found.

Two questions:

1. Any idea how to fix this? I tried but seems it is for referencing another .apk that need to install separately.

2. If I just keep it to be java project (not android) for my library, can I use the resource generator? and how?

PS: the dependency (my library) is installed before the UI test application, according to the Console of Eclipse said.

Update: I tried to compile the library project to jar and reference it from the UI testing, and in this way, it works. But I don't want to use this approach since it is very slow in terms of testing.

Answer 1

Finally I found the answer to my own question. This is actually mentioned in official documentation.

Answer 2

for those who are doing same mistake like me

when library project is an android project got to

properties > android > click add button at bottom of the popup inside library section

and add project, instead of

properties > java build path > project > add

later approach is for pure java projects only .
