        var doc = new jsPDF(options,'p', 'pt', 'a4');  

        var number_needed_pages = canvas.height / 900;

        {

         canvas2.width = 794; canvas2.height = 900;  

         var context2 = canvas2.getContext('2d');    

         context2.drawImage(canvas1, 0 , 0 + 900*x , canvas1.width, canvas2.height, 50, 0,  canvas.width, canvas2.height); 

        doc.addImage(canvas2.toDataURL('image/png'), 'JPEG', '', '', '');  

        doc.addPage();

    doc.save("output_file.pdf");

You must specify a path to Genymotion folder to use this feature (Android Studio)

what to do:

1. Open Genymotion itself (the round & pink icon on your desktop).

 2. Choose the "Settings" option from the upper menu.

 3. Choose the option "ADB" from the upper menu.

4. Select "Use Android custon SDK tools". Put the following path inside "Android SDK": C:\Program Files\Genymobile\Genymotion

 Why does it happen? you're getting the notice "You must specify a path to Genymotion folder to use this feature" because there's a bug in Genymotion working on Windows that misleads the Genymotion engine while trying to use the Android SDK.
