The technique involves the usage of "droppers," a term denoting a dual or multiple-stage infection process in which the first stage malware is often a simplistic threat with limited capabilities, and its main role is to gain a foothold on a device in order to download more potent threats.
Droppers are very effective on the mobile scene
But while on desktop environments droppers aren't particularly efficient, as the widespread use of antivirus software detects them and their second-stage payloads, the technique is quite effective on the mobile scene.

The reason is that droppers require a smaller number of permissions and exhibit limited behavior that could be classified as malicious. Furthermore, adding timers that delay the execution of any malicious code with a few hours also helps the malware remain undetected during Google's scans.
Google's uphill battle
"It is quite difficult to detect dropper apps," the expert told us. "As you can imagine threat actors will put a lot of energy in keeping those apps undetected."

I use a adblock browser and occasionally a google chrome variant but I rarely ever spent any serious time online from a smartphone on Android. The first time I seen how some apps try to trigger a website-webpage I knew there was trouble coming to paradise.

With mobile devices it's tricky stuff to yank that garbage out once it embeds. Lucky for some of us we got our nose deep in the internals somewhat similar to Windows where you can drill in and down to the core of matters and work your way up the chain to guard most vulnerable access points but it's never a done deal even with that.

AND, as far as the Play Store, it's easy to see now that it's a cat an mouse game trying to fish out the sneaks.
