<div dir="auto"><div>Hi Chime,<div dir="auto"><br></div><div dir="auto">Strictly speaking not all apps are graphical. But that isn't exactly what you are asking I expect. Most apps that you interact with do bring their own UI. While Android apps typically have a visual UI, they often support accessibility to varying degrees which should help navigating the visual interface with appropriate callouts for buttons and input fields and the like. </div><div dir="auto"><br></div><div dir="auto">While I am not sure if apps installed through one of the app stores allows for apps to be executed from a separate terminal emulator, I would guess that a terminal emulator might provide a method for installing additional terminal apps. <span style="font-family:sans-serif">(Specifically since apps are usually sandboxed I don't know if one app can directly invoke another separately installed app except through intents which are not really standardized for this use case as far as I know)</span></div><div dir="auto"><br></div><div dir="auto">As far as your app "disappearing", it sounds like you were descibing the app being closed after a period of inactivity. This is quite normal and expected in Android for apps which are in the background to be closed at any time. Often this is related to memory management but it can happen at any time.</div><div dir="auto"><br></div><div dir="auto">I have never looked at alternate sources for apps so I cannot provide any useful insight there. </div><br><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, May 5, 2019, 5:56 PM Chime Hart via SGVLUG <<a href="mailto:sgvlug@sgvlug.net">sgvlug@sgvlug.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi All: I purchased a Chrome Book, `marvelous Android type speech.

a Linux Beta, which has more options than Crowsh. I wanted to have a defalt of <br>
TCSH, but for some reason it didn't seem to take. Also, seems with maybe <br>
20minutes of inactivity, the shell is gone, eventually even hidden from the <br>
menu.<br>
OK, so I know we can install Android apps in Linux. I installed "anbox" I <br>
thought, "sure I would install a Uverse app, so I can access a DVR, with <br>
speech". However, 1 of my Linux experts says all Android apps are graphical. By <br>
chance, are their any commandline apps-and-if so, are their repos I can add in <br>
my Debian machine to enjoy them?<br>
I also installed qemu, but I think that is only graphical? Thanks so much in <br>
advance for any guidance<br>
