I have this bootup app that listens to the system boot up event and will launch on system start up (pardon the verbosity).
Problem is, the system will stubbornly show the homescreen (or a static wallpaper, I'm not so sure, basically it's a colorful, mostly blue geometry pattern, see the picture below) first before switching to my app, which is quite annoying.
I assume I need to delete files under /data/data or /system/priv-app to eliminate that?
Can someone please help me?
I'm running a customized (with heavy samsung influnece, I'm not the system level guy) build of android 5.1.
