Since Google upgraded Market to Play Store, any download/installation of application must be done on registered Android devices (i.e. branded Android devices passing CTS), so for devices that are under development phase, if want to install some interesting applications presented on Play Store, we can do in the following way:
1. Install Real APK Leecher application Real_APK_Leecher.zip;
2. With JRE env, execute Real APK Leecher, you input a registered Android cell phone' Device ID (You can get it via typing *#*#8255#*#* in dial pad on a branded Android cell phone), and your gmail account;
3. Then you can retrieve application, and select to download, then "adb install" to FSL reference boards.
Another way presented on internet based on Chrome 17+ and "APK Downloader" extension DO NOT work because Chrome will upgrade to latest release that claims ONLY accept and install extensions (i.e. plugin) from Google Web/Play Store, so "APK Downloader" extension cannot be plugin in Chrome latest release due to not authenticated.
NOTE: This "Real APK Leecher" may not work in future due to Google upgrade the authentication procedure.
