android - Will apk installed manually (not from play store) receive notification when update becomes available? -

i want preinstall apk on tablet (know how it). will tablet receive notification play store, update ready on play store , should install it? to preinstall apk, need device oem; how gets done depends on exact environment. if apk has no native libraries internally, can safely place apk in firmware image (in same location standard apk suite). beyond that, (for example, similar i've seen in motorola devices) create special directory (such /preinstall) , have script perform "pm install ..." each file in location items not installed. regarding updates, people have commented: no problem since you're not changing package name. increase package version store upload. also, safety, upload package (older version, non-functional ok) store in order reserve package name on store -- otherwise place own on store before you.
