Hello all, I want a very basic application for Samsung galaxy S2. It has got android 2.3.4 Application would have 4 pages in total. There will be a dummy landing page when you launch it. When you type the correct password it will go to the second page where you will have a button to record, 4 radio button to select the quality and a button to see the list of recordings. Application has to hidden from Active applications menu. User should not be able to close the program. It needs to be done as soon as possible. I only need it on samsung galaxy s2. No payment upfront.
