Disassembling Android app

It turns out that Google recommends obfuscating your Android app.

In order to understand the problem, I would like to disassemble my own app and see what information I 开发者_运维百科can extract from the code. How do I do this?

There are tools available for that, such as the pair linked to in this sentence. I have not used them and therefore cannot vouch for how well or easily they work.

Some tools are listed at What is a good android disassember that can produce infomative results

Also you can try undx http://undx.sourceforge.net/

Use them only for good :)
