创建android外部jar作为库，找不到资源

Question

I got a problem when I tried to do this:

LinearLayout container = (LinearLayout)findViewById(R.id.chat_list_container);

android.content.res.Resources$NotFoundException: Resource ID #0x7f030001

This is a code from external jar I have just created and added to my application.

By the way this exact code working when I used it as import module and not use it like external jar.

Any help?

Thanks!

Android will not look for resources in any external jar because they are expected to contains just executable code.

If you want to publish resources as library as well, things gets more ugly. In this case, you could create a resource apk just like framework-res.apk. To do that, create an android project with no source, place the res files and add this to your AndroidManifest.xml:

...
<application
    ...
    android:hasCode=false >
    ...
</application>

In this case, you will have to retrieve the res id directly from the res-apk:

int resId = getPackageManager().getResourcesForApplication("res.apk.package.name")
.getIdentifier("chat_list_container" , "layout", "res.apk.package.name");

// Maybe getResources.getIdentifier() works, but I'm not sure.
LinearLayout container = (LinearLayout)findViewById(resId);

I should mention that the device which will run the application must also has the resource apk installed.
