Answer
The log message --
"Caused by: java.lang.ClassNotFoundException: com.google.android.maps.MapView in loader dalvik.system.PathClassLoader[/data/app/com.example.searchmap-2.apk]
Clues you in that you appear to be running on a device without Google Maps API on it. If it is an emulator go to your AVD manager and create a new AVD with a target that has "Google APIs (Google Inc.) -- API Level X" where X is your target API.
If this is a real device, it looks like you have one without google maps support, try in the emulator.
