Deliverable #1

Description:

• Deliverable 1 is about writing a test program in order to use GPS feature for our phone application. Currently the application is able to simulate the location within the emulator by sending in the coordinate with DDMS tool. In order to use the Google map, it is necessary to obtain a Maps API Key by getting the MD5 Fingerprint of my signing certificate, getting the MD5 fingerprint of the SDK debug certificate and then registering the certificate fingerprint with the Google Maps service.

My progress:

• Done of write a test program to receive the DDMS tool simulated location and display the location within emulator.
• Done of write a test program to display the location with Google map.

• Sign the application.
• Obtain Google Maps API Key.
• Download the application to the phone.
