Hi everyone,
I am a beginner of android programming, these several weeks I am
trying to write a RSS reader.
As I said, I use SAX to retrieve the elements from xml of a website.
All other elements I can retrieve except the content inside the
<content:encoded>.
Below is my Handler.java
can anyone help me?
thz so much~~~
