... to pick a location from a map (i.e. "Where was this photo taken?")
Example Usage
This android java code will show a map with 3 markers:
Intent mapIntent = new Intent();
// we want to view the map
mapIntent.setAction(Intent.ACTION_VIEW);
// this will be shown as primary marker in the map
// the coordinate 53.2,8.8 is in north germany where the map is centered around
// z=1 means zoomlevel=1 showing the continent
// the marker's caption will be "primary marker"
Uri uri = Uri.parse("geo:53.2,8.8?q=(primary+marker)&z=1");
mapIntent.setDataAndType(uri, null);
// this is the maps Caption
mapIntent.putExtra(Intent.EXTRA_TITLE, "Hello Map");
// the map will contain 2 additional point of interest
mapIntent.putExtra("de.k3b.POIS",
"<poi ll='53.1,8.9'/>\n" +
"<poi ll='53.3,8.7' n='Say Hello' \n" +
" link='https://github.com/k3b/LocationMapViewer/' \n" +
" d='This will be shown as a Marker. When clicking on the marker you " +
"get this text and a link to LocationMapViewer' />");
try {
startActivityForResult(Intent.createChooser(mapIntent,"Choose app to show location"), 4711);
} catch (Exception e) {
e.printStackTrace();
}
GeoIntentDemoActivity.java is the sourcecode of a complete android demo app that uses LocationMapViewer (or any other provider that supports "geo:" uris)
Minimal requirements:
Android-2.3.7 - Android-7 (API 10ff) for version v0.3.5.170911(6)
Android-4.1 and later (API 16ff) for version v0.3.7.210429
internet/wifi-connection to download geodata and a SD-Card to cache geodata
Requred permissions:
INTERNET: to download map data from Open Streetmap Server
ACCESS_NETWORK_STATE and ACCESS_WIFI_STATE: to find out if wifi/internet is online to start downloading mapdata
WRITE_EXTERNAL_STORAGE
to cache downloaded map data in local file system
to load gpx/kml-Files to be displayed in the map
ACCESS_FINE_LOCATION and ACCESS_COARSE_LOCATION: to display my own location in the map
Note: the app that uses LocationMapViewer via the intent api does not need these permissions.
