How can I use it?

To use GoHomeMail is very easy! Let's take a quick tour.
  1. Get the app and at least one plugin app from Google Play.

  2. Launch GoHomeMail, then you'll see the main screen like below.
    • There are only five steps:
      1. Set up plugins.
      2. Set your home location.
      3. Choose how to go back home.
      4. Input your fresh comment.
      5. Send the message.
      Once you did step#1-3, you might have to do step#(4-)5 since next time.
        If you see some dialogs, please follow the messages.

        In most cases, you have not installed any plugins yet. In the case, please check out Google Play to to get a plugin. If you open Google Play from the following dialog, it searches plugins automatically.

        Also you may see a "Term of Use" and "Privacy Policy" dialog. GoHomeMail would like to ask users to view the application use policy at least once. You can just tap the "Term of Use& button to open the "Term of Use" web page easily. Then the dialog never appears. On viewing the page and after geting back from Browser showing the webpage, users will not see the dialog as well.  Sorry for inconvenience, but this is a sort of important things...

        Finally, you may see a license check failure dialog like below.  This happens mostly when you are offline.  It means Google Play app cannot connect to the central server to check the app validation.  In the case of offline, users can ignore it selecting the "Cancel" button.  But please note this application is a kind of network apps so that it doesn't work expectedly without network.  Also you can retry license check tapping "OK".  GoHomeMay just invoke the license check process again.

  3. Set up plugins.

  4. Set your home location.
    • If you tap this menu bar, you'll see a next screen with map. Please drag the map view to show your home. Then tap the center of the map to indicate your home in the center. Please map the locator icon to your home.
      You can use the text box of the top to search your home location quickly. Please input (a part of) your address, then tap the button of "search".
      Finally, tap the bottom button of "Set home place" to commit the position. GoHomeMail will get the longitude and latitude from Google Maps.
      Please note this setup uses Network function. So you have to enable Network connection beforehand.

  5. Choose how to go back home.
    • After setup your home location, GoHomeMail will show the address and simple map under the menu bar of "Set home place". Then next, you are being asked about how you want to go back home. There are 4 options: Walk, Car, Train, or Bike. Please choose one. By the way, please note Bike might not be supported by Google Maps in your area yet.

  6. Input your fresh comment.
    • Then, please input your fresh comment to recipients. GoHomeMail will remember the input comment for the next session.
      So you can use the same comment many times, but your recipients might expect comments of something new...

  7. Send the message.
    • Finally, please tap the last menu bar. It get GoHomeMail to find the best route to your home and send the report to recipients by the method you setup as plugin.

      The location detection will sometimes fail like the Google Maps app... However GoHomeMail can retry the operation. Please check Android notification message. Also please check your Network and GPS condition.

  8. Setup application options.
      If users press the Android "MENU" button, users can see option menus. Most of them show same dialogs explained above. But there is one menu that controls this application. If users select the "Main Settings" menu, then main preference screen of this app will appears up.

      Now GoHomeMail has one option, about the location provider selector. GoHomeMail uses location detection so one of providers users' Android device has should be available.
      Usual applications like Google Maps will use combination of GPS and Network location provider; Get coarse grained location information from Netrork (3G) at first, and obtain the exact location from GPS after then. That's because such application can keep foreground for a while, and users can wait for the accurate location information while watching the screen.

      However GoHomeMail would like to get the location information as soon as possible and to send a message immediately. It can't wait for a while to get the exact location.
      Also there are characteristic on each provider. Network provider using Wi-Fi is sometimes incorrect although it is fast. On the other hand, GPS provider is very,very slow and sometimes fails, but it is the most accurate. 

      So GoHomeMail commits the selection to users. Users can change the behavior to detect their location in the following preference screen.
