“Unable to instantiate activity” error

Question

One of my Android apps has about 100,000 users and, about 10 times a week, I get the following exception being reported to me via Google\'s market tool:

java.lan         


        

Answer 1

I had this issue but not with activity. Fixed with a workaround:

ClassLoader myClassLoader = TroubleClass.class.getClassLoader();
Thread.currentThread().setContextClassLoader(myClassLoader);
