You may want to download an Android APK file from the Google Play Store for various reasons. Maybe the files you want to download are too large to download on to your phone or perhaps you may not have access to the apps due to your location. Either way there is a method to downloading the package file from Google Play and then sideloading them on to your phone.
The easiest way for users to download an APK package file from the Google Play Store is using an extension of Chrome called APK extension downloader 1.4.3. You should download the extension by right clicking and saving the extension as something because Google has blocked it from being installed directly to Chrome. I should mention though that only free apps can be downloaded so this is not a tool that will allow you to plunder the store of its paid apps.
The app then requires you to get the JID and the Device ID of your phone. The easiest way to accomplish this is to simply download an app that will fetch the details from your phone.
The alternative way is to type in *#*#8255#*#*. If it opens the monitor then find the lines that begin with JID and Device ID then put those details into the app. Your email is the JID and your Device ID is the string after the Android prefix.
Once you get those details enter them into the extension and then you can navigate to the download page in the Play Store and then click on the extension icon to download the app that you want.
You should note though that using this method to access apps in the Google Play Store is against the store's terms of service, so use it at your own risk.
