Is it possible to start an Android app without launching an Activity
Programming Languages

Specifically, I am looking for a way to prevent the "black screen" from showing up when I run my app.


The app just runs a quick program whenever it is pressed but since it is linked to an Activity, it loads up a layout (black). I know I could do a widget but I need it to be in the launcher....


Is there any way to do this?


Launch service from app start, not activity
Programming Languages

I want to launch a Service when the app is launched instead of an Activity; and then said Service will launch an Activity. I need to do this because my app needs to be running ALWAYS, and when I say ALWAYS I mean ALWAYS. And the only way I've managed to avoid the OS killing my app is by starting a service as Sticky and should Android kill either my Activity or my Service I'll restart them right away.


I found this question but the top answer seems rather clumsy, any one has a better idea?


PS: I know this doesn't look like a very friendly app but this is a very specific research scenario and it's not intended for regular user
