Android, Insert a variable into an URL

Question

I have this code's string:

Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("http://maps.google.com/maps?f=d&saddr=37.4,-121.9&daddr=Bellevue WA&hl=en"));

Using this code, Google maps creates the path from coordinates "37.04,-121.9" to "Bellevue". Now I wouldn't to add in the path the static coordinates (37.04;-121.9) but 2 variables called "long" and "lat". How I can do? like this:

   Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("http://maps.google.com/maps?f=d&saddr=long,lat&daddr=Bellevue WA&hl=en"));

but in this way, it doesn't work. Anyone can help me? Thanks

You have to construct the URI String first.

You can use:

String uri = String.format("http://maps.google.com/maps?f=d&saddr=%1$s,%2$s&daddr=Bellevue WA&hl=en", long, lat);
Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));

%1$s,%2$s? what are? in my case are: %lat$s and %long$s? – Giacomo Brunetta Aug 15 '15 at 02:03
%1s, %2s will be replaced by long and lat variables. – Raymond Lukanta Aug 15 '15 at 02:05
I don't understand...why? – Giacomo Brunetta Aug 15 '15 at 02:09
See on the end of the code, I have `, long, lat`. That will replace the %1s, %2s. – Raymond Lukanta Aug 15 '15 at 02:10
ahhh okok, excuse me, now I'll try – Giacomo Brunetta Aug 15 '15 at 02:12
