Question

I would like to know if i can link my application with a app like google maps? For example If i create a button and onClick I go to Google maps app.So is there a way i can direct the onClick event of the button directly to the maps?If so how do I do it?

Answer 1

You can do it with intents, if you want to open google maps from your app, you can do it with this code:

String uri = "geo:"+ latitude + "," + longitude;
Intent myMapIntent = new Intent(android.content.Intent.ACTION_VIEW, Uri.parse(uri));
startActivity(myMapIntent);

You can find some useful info about that in the related Android Documentation

Answer 2

You can use

geo:latitude,longitude
geo:latitude,longitude?z=zoom
geo:0,0?q=my+street+address
geo:0,0?q=business+near+city

From the Android Developer guide

Answer 3

Intent intent = new Intent(android.content.Intent.ACTION_VIEW, 
Uri.parse("http://maps.google.com/maps?saddr="+mylocation));
startActivity(intent);
