Android - How to launch Google map intent in andro

Question

Map Intent not working with specific zoom level as well as custom marker

    float lat = 40.714728f;
    float lng = -73.998672f;

    String maplLabel = "ABC Label";
    final Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
            Uri.parse("geo:0,0?q="+lat+","+lng+"&z=16 (" + maplLabel + ")"));
    startActivity(intent);

Anybody know what is wrong? or how to do so? I want to show map of certain (lat,lng) with a custom label-marker at a specific zoom level.

Answer 1

Show location in maps application:

Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
String data = String.format("geo:%s,%s", latitude, longitude);
if (zoomLevel != null) {
    data = String.format("%s?z=%s", data, zoomLevel);
}
intent.setData(Uri.parse(data));
startActivity(intent);

Answer 2

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

Answer 3

Try the following solution:

double latitude = 40.714728;
double longitude = -73.998672;
String label = "ABC Label";
String uriBegin = "geo:" + latitude + "," + longitude;
String query = latitude + "," + longitude + "(" + label + ")";
String encodedQuery = Uri.encode(query);
String uriString = uriBegin + "?q=" + encodedQuery + "&z=16";
Uri uri = Uri.parse(uriString);
Intent intent = new Intent(android.content.Intent.ACTION_VIEW, uri);
startActivity(intent);

I believe the problem had to do with the spaces in your label. Encoding the query string will eliminate the issue by replacing the spaces with valid characters
