I have found that when a Custom View class which loads a designer layout is compiled to a library, the required .bjl file is not included in the jar. When the Custom View class is then used in another app it will compile correctly, but has a run time error because the designer layout file is missing. If this file is then copied to the associated Files folder the app will run correctly. The attached filed demonstrate the problem. Have I missed somethin, or is this a problem?
