(adsbygoogle = window.adsbygoogle || []).push({}); this is tec. a jailbreak for your android.
YOU NEED [APP INSTALLER ] IN ORDER FOR U TO GET THE APP DOWNLOADED!
you get free apps that you would normally have to pay for on the market.
first you find a app u want but dont Wanna pay for.(ex robo defense)
you would go on your computer and type in the app then apk after it (ex. robo defense apk)
google is the best for this!
then you just download the file onto your computer.
then you plug in your android to your computer and move the apk file to your phone.
then you use appinstaller app to download it right onto your phone.

This is a quite obvious method of downloading apps, but sometimes we miss obvious things.

If you head over to me Andriod tutorial you can download all Paid Apps for free (link is in my signature)
