Cannot load Framework Security on Android
Hi,
I'm having a problem loading the OSGi Framework Security extension on
Android. I am trying to load Framework Security version 1.4.2 into Felix
version 3.2.2. The exception I get is: "Unable to add extension bundle
to FrameworkClassLoader - Maybe not an URLClassLoader?"
The exception comes from the Felix ExtensionManager, which attempts to
create its private instance by adding a new URL to the system class
loader, which is obtained from Felix.class.getClassLoader(). However,
since Android uses the PathClassLoader rather than a URLCLassLoader,
this fails - rendering the ExtensionManager inoperable.
Because of this, it appears to be impossible to load framework security
on Android at the moment. Does anyone have any ideas or workarounds?
Reference:
http://svn.apache.org/repos/asf/felix/branches/org.apache.felix.framework-3.0.8-RC/src/main/java/org/apache/felix/framework/ExtensionManager.java
Thanks,
Darren

Hi
You need to add org.apache.felix:org.apache.felix.ipojo.annotations as a
dependency.
All that you need is probably described here :

I'm trying to to create OSGI services using iPOJO annotations and
maven. Does anyone know if there is an example like this one that uses
iPOJO annotations instead of XML? I've found some annotations

Re: Cannot load Framework Security on Android
Posted by Karl Pauls <ka...@gmail.com>.
There is no real need to install the security provider as an extension
bundle. You could put it on the classpath of the app and pass its
activator as a system bundle activator. That way you should be able to
work around the issue. However, I never tried to use it on android and
Im not sure it will work - if you try it please let us know what the
result was :-)
regards,
Karl
