startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("geo:LAT,LON")));
does it, where LAT and LON are latitude and longitude in decimal form,
negative numbers for the Southern and Western Hemispheres, respectively.
So, pulling an example from (*cough*) one of my books:
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class LaunchDemo extends Activity {
private EditText lat;
private EditText lon;
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
Button btn=(Button)findViewById(R.id.map);
lat=(EditText)findViewById(R.id.lat);
lon=(EditText)findViewById(R.id.lon);
btn.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
String _lat=lat.getText().toString();
String _lon=lon.getText().toString();
Uri uri=Uri.parse("geo:"+_lat+","+_lon);
startActivity(new Intent(Intent.ACTION_VIEW, uri));
}
});
}
}
That, given a layout with two EditTexts and a Button, will launch Google
Maps on the specified coordinates.
And, yes, I probably should use StringBuilder or possibly
String.format() rather than the concatenation...
