Android application bug fixes

I have an Android application that has some bugs that need fixing. I need an experienced Android developer who can fix these bugs, clean up the code and make it run more efficiently. Areas that need cleaning up are: 1. The download of data to happen once during the valid period. Check for new data should only happen after the date of the current download has passed. 2. Once the date of the current download has passed, the data should not be presented to the user. It currently does that. 3. The app uses a library project which works with an average 80 to 90 images. The app is very slow to load taking between 1 and 2 seconds to load. The library project is at [login to view URL] This needs to be made faster to load. 4. Positioning of cursor within a list view. 5. Reformat 1 view which is not properly formatted. 6. Clean up code, especially code that runs when the app is launched. Please note I will not be able to answer all questions posted, so you are better off sending me a bid and I'll have a look at your Android experience on VWorker and make a decision based on that. Experience working with Amazon Web Services is a plus, but not mandatory.
