I want to save the text of my inputfield
"Hi everybody,
I have the following problem: I'm developing an App where I have to use some input fields. As a user, when I write in my input field on Android devices and I receive a call or decided to switch to another App without finalise push an "Ok" button to save the text I started to write in the input field, when I return to the App the text in the input field is lost. This is problematic because in some cases the text can be long and if for any reason the user has to attend some other action on the phone without finish all the text entering, then the user has to write everything again. This is not the case e.g. in Whatsapp: when I start to write a message but switch to another App without push the "send" button, when I go back to Whatsapp, the message's text is still there. Does anybody know how this text can be kept in the input filed in these cases? Is any special property or a special input field that can handle these situations? Or is necessary to program this functionality for the input filed?
Thanks and regards"
