Network Programming in .NET

If you want to show a map in your Phonegap app, you can always use the google maps API to show a map, or even use the in-app browser to link out to a google map page. But nothing quite matches the Google maps native app, with it’s funky satnav-like features, and slick interface

Thing is, the Google Maps App isn’t installed by default, so in this case, I’m failing-over to a in-App Browser version. This code is iOS only, but anyone wishing to provide a port to Android will be rewarded* (Yes, I’d pay for the port)

– (void) openGoogleMaps:(CDVInvokedUrlCommand *)command

{

NSLog(@”openGoogleMaps”);

NSString* callbackId = [command callbackId];

NSArray* arguments = [command arguments];

NSString* map = [arguments objectAtIndex:0];

CDVPluginResult* result;

NSURL *testURL = [NSURL URLWithString:@”comgooglemaps://”];

if ([[UIApplication sharedApplication] canOpenURL:testURL]) {

NSString *directionsRequest = [NSString stringWithFormat:@”%@%@”,

@”comgooglemaps://?” ,

map];

NSURL *directionsURL = [NSURL URLWithString:directionsRequest];

[[UIApplication sharedApplication] openURL:directionsURL];

result = [CDVPluginResult

resultWithStatus:CDVCommandStatus_OK

messageAsBool:true];

} else {

NSLog(@”Can’t use comgooglemaps:// on this device.”);

result = [CDVPluginResult

resultWithStatus:CDVCommandStatus_OK

messageAsBool:false];

}

[self success:result callbackId:callbackId];

}

Then, this is called from Javascript as follows:

function openGoogleMaps(route)

{

console.log(“openGoogleMaps”);

cordova.exec(function(data)

{

console.log(“Returned from google maps:” + data);

if (!data)

{

// Failed to find native app.

var strUrl = “http://maps.google.com/maps?”;

strUrl += route;

var ref = window.open(strUrl, “_blank”, “location=yes”);

}

}, function(data)

{

console.log(“Plugin failure”);

}, ‘StatusBar’, ‘openGoogleMaps’, [route]);

}
