1. An app that scans all the photos on the phone and for any with GPS co-ordinates displays a marker on a map.
Using the relevant Android media access API find all the images on the phone. For each image examine it to see if there is non visual metadata, such as the GPS co-ordinates of where the picture was taken. If there is a location then use the Google Maps API to show a map with a marker of the GPS location of each image. Tricky parts: scanning the images for GPS co-ordinates. I haven't looked to see if Android has this capability. If it doesn't there is probably open source java libraries that can do this. 2. An app that scans all the SMS messages on a phone and shows a histogram of the number of messages sent to each contact in the address book. Open the SMS inbox using a cursor on the ContactContract URI. Scan each message and build a list of the name of recipient of each message with a count of the number of messages sent to that recipient. Display the results in some form. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
