【實用工具app】Crash Alert|最夯免費app-綠色工廠好玩App

This application uses the accelerometer embedded in an Android device to detect car accidents and, after detecting a crash, will automatically send a customizable SMS to a user-provided number, detailing the location (expressed in decimal degrees for both latitude and longitude) and the time of the accident.

While running this application you should avoid using a flexible arm holder to position the Android device inside a car, because testing has shown that any kind of oscillating holder can hinder the reliability of the application and cause some false positives: you should instead use a holder that can be locked into position and doesn't move while you're driving.

On the other hand, using a belt clip or keeping the device in your pocket doesn't seem to affect the reliability of the application, as long as the GPS module can determine the current location.

For similar reasons, you should also avoid moving the Android device while the detection service is running, since any sudden movement could cause a false positive.

Be advised that this application requires an accelerometer with a maximum range of at least 19,4 m/s^2 (about 1,98 g) in order to work.
