Android :: Launching Google Maps And Navigator From Application

I have an android application which allows the user to open up google maps or navigator to show a certain address. This functionality was working in the past, but now I get the following error and the app crashes:
ERROR/AndroidRuntime(2165):
android.content.ActivityNotFoundException:
No Activity found to handle Intent { act=android.intent.action.VIEW
dat=google.navigation:q=MCNAMARA+TERMINAL+ROMULUS+MI+48174 }

The two intents I'm using are-

1) For Map:
String uri = "geo:0,0?q=MCNAMARA+TERMINAL+ROMULUS+MI+48174";
Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
startActivity(i);

2) For Navigator:
String uri = "google.navigation:q=MCNAMARA+TERMINAL+ROMULUS+MI+48174";
Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
startActivity(i);
