SMS my GPS

This android app is designed to automatically send your location in response to an SMS from a permitted phone number with a pre-agreed prefix.

To set this up simple add the permitted numbers with the corrosponding pre-agreed prefix to the app. The app will then send an SMS containing your coordinates in response to an appropriate SMS message.

This fork is based on Anevero's project which is, in turn, based on Warren Bank's project.

Features

• Add any items and corresponding prefixes to the app. You can edit already added items later or delete them. You can add the number by choosing the appropriate contact or manually. It's better to use full number format with the country code (but the app still will work with short numbers, because actually it checks number postfix match).
• Enable the foreground service. While working, it checks all the incoming SMS, and if the match is found, sends an SMS as a reply. When service is running, the corresponding notification is shown in the notification area.
• Set up location providers to use. Several ones are available; each can be better than others in some situations (check their descriptions in the app). Each provider initiates sending the corresponding message (so if you enable several providers, the app will send several messages with the location info from each of them).
• Set up location accuracy and maximum location requests number. When the app needs to get the location from the provider, it will make requests to the provider until the necessary accuracy or the maximum attempts number is reached, and send the location only after that. One request to the provider usually takes around 5 seconds. This feature allows getting a much more accurate location because different device sensors (for example, GPS) often need some time to determine the real location.

Changes in the fork

• Allowed sending a location-request SMS from within the app. This is necessay on phones which use RCS messaging by default, as in this case it is awkward to send an SMS.
• Allowing stored numbers to optionally have names recorded. This is simply to ease number management.
