Android Question App Installation from Unknown Source

[AndroidMadhu]

Hello,
I am trying to implement to activate the option App Installation from Unknown Source.
I have uploaded my App in my website, from where users will download and install the app.
But I am not sure about how to implement the feature App Installation from Unknown Source during new App installation from my website.

I am following the below link ...

Please advice as how to integrate the above during new installation.

Thanks

You CAN NOT do it for the first installation. At least i think this is not possible without user interaction. Means; User need to download the apk and run the Packageinstaller with the apk to install it. Note if he (the user) download the app using an email app (reading a mail with a attachment) then the emailapp needs to have the rights to install 3rd party apps.

The Code from the tutorial above only applies to UPDATES which is done by the app itself.
