You might have gone with the similar problem when you are installing some application on your Android Mobile Phone, and it says, “For security, your phone is set to block installation of applications not obtained from Android market.”.
That’s ok, no need to worry about it.
This is done by default to block those applications which are not from the Android market, because they could steal your personal data or could contain some harmful data structures. So take the precautions before installing any non-market apps on your android phone such as checking its’ author and genuineness etc.
Well, now coming onto the point,
follow the procedure to install the non-market apps on your android phone,
- First of all Go to Main Menu > Settings
- Now look an option named Applications, click on it
- probably the first option would be Unknown Sources (Allow Installation of non-Market Applications) – Just Select this option by clicking on it
And here you’re done with it.
Now to install app on your phone just download any .apk file on your Computer and install it on your android phone.
And after installing the authentic apps on your Android Phone, remember to switch the Non-market Apps Installation OFF (by de-selecting the option which you did by the above provided method), just for a few security reasons.
