What have you tried? This Project is not difficult to code.
Sending the eMail
This example works to send eMail . You must run this in a real Android device (not an emulator). Most emulators will not support the ActivityStarter action. So far, it has ‘never failed.’ to transfer the Subject and content to gmail. Try coding the ActivityStarter using the example. Tell us what happens. The SurveryResults contain the vallues of
- level of fuel (sliding bar) - [slide value]
- level of water (sliding bar) - [slide value]
- number of hatches - [insert value]
after you provide the code.
The way to create this app is to learn to use a slider, TextBox etc., then learn to create an eMail containing the values. Alternatively, when you are more experienced in coding, you can send the values to a Shared GoogleSheet on your GoogleDrive.
Creating the sliders and TextBoxes
