The BlackBerry developers implemented in the new OS (10.2) the ability to install and run Android APK files. Because this is a new technology, some applications could encounter compatibility errors. To install an APK file (like Google Chrome) on your BlackBerry, you first need to download or transfer the file to the device. To download the APK file, you can use a tool like APK Downloader(use Google to find it). To transfer the file to the device you can use any method that suits you, cloud storage, transfer using the USB cable from PC, email. After the file is on the device, open it. Before you can install it, you will be prompt to deactivate some security features. After this is done, the application (Google Chrome) will be available among the other installed applications from your BlackBerry.
