3. buka file javanya. (mainactivity.java)
|
package com.lukmanrheza10;
import
android.location.Criteria;
import
android.location.Location;
import android.location.LocationListener;
import
android.location.LocationManager;
import android.os.Bundle;
import
android.app.Activity;
import
android.content.Context;
import android.view.Menu;
import
android.widget.TextView;
import
android.widget.Toast;
public class MainActivity extends Activity implements LocationListener{
private TextView latituteField;
private TextView longitudeField;
private LocationManager locationManager;
private String provider;
@Override
protected void onCreate(Bundle
savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
latituteField = (TextView)
findViewById(R.id.tv2);
longitudeField = (TextView)
findViewById(R.id.tv4);
// Get the
location manager
locationManager =
(LocationManager) getSystemService(Context.LOCATION_SERVICE);
// Define the
criteria how to select the locatioin provider -> use
// default
Criteria criteria = new Criteria();
provider = locationManager.getBestProvider(criteria,
false);
Location location =
locationManager.getLastKnownLocation(provider);
// Initialize the
location fields
if (location != null) {
System.out.println("Provider
"
+ provider + " has been
selected.");
onLocationChanged(location);
}
else {
latituteField.setText("Location
not available");
longitudeField.setText("Location
not available");
}
}
/* Request updates at startup */
@Override
protected void onResume() {
super.onResume();
locationManager.requestLocationUpdates(provider, 400, 1, this);
}
/* Remove the locationlistener
updates when Activity is paused */
@Override
protected void onPause() {
super.onPause();
locationManager.removeUpdates(this);
}
@Override
public void
onLocationChanged(Location location) {
double lat = (double)
(location.getLatitude());
double lng = (double)
(location.getLongitude());
latituteField.setText(String.valueOf(lat));
longitudeField.setText(String.valueOf(lng));
}
@Override
public void
onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}
@Override
public void
onProviderEnabled(String provider) {
Toast.makeText(this, "Enabled new
provider " + provider,
Toast.LENGTH_SHORT).show();
}
@Override
public void
onProviderDisabled(String provider) {
Toast.makeText(this, "Disabled
provider " + provider,
Toast.LENGTH_SHORT).show();
}
@Override
public boolean
onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to
the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}

4. Buka androidmanifestnya
Cukup denagn menambahkan 3 buah permission. yaitu:
|
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.INTERNET"/>
|

5. monggo di running...
kalau awalnya masih not avaliable...
selanjutnya buka DDMS dan pilih send pada tab menu emulator control
