APKMirror Chrome Extension - Add Features and Enhancements to Your Google Play Store
I just tried this on my Fire 7 that I purchased on Black Friday and it worked. Use -inc/chrome/chrome-62-0-3202-84-release/chrome-browser-62-0-3202-84-4-android-apk-download/download/ version and it was able to install successfully.
I have installed other apps on my Fire 8 using apk mirror and have had no problem. But I am having a problem with the chrome one. It downloads and seems to be installing correctly until the end when it says. Did not Install. I know it is installed because at a time I am able to click a choice to open with chrome or with silk. My problem is the app is not showing on my home screen or in the apps list. Is there a way to get the app button.
Instead Android apps are shipped as bunch of APK files the app is split into. The file you have downloaded from apkmirror contains such a bunch of APK file. For your convenience they are ZIPed into one file so you don't have to download half a dozen APK files.
