why Can't I see the map

why Can't I see the map - android

I want to run demo Google map but it is not showing map. Here is my code.I have checked API key it is correct
package com.example.googlemaps;
import com.google.android.maps.MapActivity;
import android.os.Bundle;
import android.view.Menu;
public class MainActivity extends MapActivity{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return true;
}
}
Manifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

</activity>
</application>
</manifest>
layout xml
<?xml version="1.0" encoding="utf-8"?>
<com.google.android.maps.MapView

android:id="#+id/mapView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true"
android:apiKey="#string/Api_key"
/>

This is old way for getting map. Google has updated it now.
use
<fragment
android:id="#+id/map"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
class="com.google.android.gms.maps.SupportMapFragment" />
in your xml layout.
provide your API key in manifest file as
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="YOUR-API-KEY" />
in your application tag.
also don't extend MapActivity. Instead extend normal Activity
then write below code in your OnCreate
int status = GooglePlayServicesUtil
.isGooglePlayServicesAvailable(getBaseContext());
if (status != ConnectionResult.SUCCESS) {
// Google Play Services are not available
int requestCode = 10;
Dialog dialog = GooglePlayServicesUtil.getErrorDialog(status, this,
requestCode);
dialog.show();
} else {
// Google Play Services are available
// Getting reference to the SupportMapFragment
SupportMapFragment fragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
// Getting Google Map
myMap = fragment.getMap();
// Enabling MyLocation in Google Map
myMap.setMyLocationEnabled(true);
// Getting LocationManager object from System Service
// LOCATION_SERVICE
LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
// Creating a criteria object to retrieve provider
Criteria criteria = new Criteria();
// Getting the name of the best provider
String provider = locationManager.getBestProvider(criteria, true);
// Getting Current Location From GPS
Location location = locationManager.getLastKnownLocation(provider);
if (location != null) {
onLocationChanged(location);
}
locationManager.requestLocationUpdates(provider, 20000, 0, this);
}
also add following code on OnResume
int resultCode = GooglePlayServicesUtil
.isGooglePlayServicesAvailable(getApplicationContext());
if (resultCode == ConnectionResult.SUCCESS) {
} else {
GooglePlayServicesUtil.getErrorDialog(resultCode, this,
RQS_GooglePlayServices);
}
that's it.
All the best!

Version 1 googlemaps officially depricated.so just use version 2 and add google-play-services libs.surely it will help to get googlemap.
public class MainActivity extends FragmentActivity {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mGoogleMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map))
.getMap(); } }

LatLng latLng = new LatLng(13.05241, 80.25082);
map.addMarker(new MarkerOptions().position(latLng).title("Raj Amal"));
}}
Plz if anyone can help

Update
First of all check that you have googleplayservice library added in your project, Then
Use FragmentActivity. Activity is not from v4 nor from v7 support libraries. This should work:
public class MainActivity extends FragmentActivity {
GoogleMap googleMap;
in onCreate
int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getBaseContext());
if(status!=ConnectionResult.SUCCESS){
int requestCode = 10;
Dialog dialog = GooglePlayServicesUtil.getErrorDialog(status, this, requestCode);
dialog.show();
}else {
SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
googleMap = fm.getMap();
}

Google Maps API V2 Blank Map

I am trying to make a WebView application with Google Maps, but when I run it, it just shows a blank map.
This is my MainActivity.java
public class MainActivity extends ActionBarActivity {

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN);
setContentView(R.layout.activity_main);
mWB = (WebView) findViewById(R.id.mWB);
mWB.setWebViewClient(new MCWC());
WebSettings webSET = mWB.getSettings();
webSET.setJavaScriptEnabled(true);
mWB.loadUrl("http://www.tomshardware.com/");
Button btnEins = (Button) findViewById(R.id.bntmap);
btnEins.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
Intent intencion = new Intent(v.getContext(),maps.class );
startActivity(intencion);
}
});
}
public class MCWC extends WebViewClient {
public boolean ShouldOverrideLoading(String url,WebView view){
view.loadUrl(url);
return true;
}
}
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_DOWN) {
switch (keyCode) {
case KeyEvent.KEYCODE_BACK:
if (mWB.canGoBack()) {
mWB.goBack();
} else {
finish();
}
return true;
}
/**#Override public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long

int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}**/
}
return false;
}
}

public class maps extends Activity implements OnMapReadyCallback {
UiSettings mapSettings;
private final LatLng GEVGELIA = new LatLng(41.1421756,22.5026124);

I already checked my SHA1 fingerprint and the API Key,
I even tried regenerating a new API Key,
I have to mention that when I run it from android studio to my device it shows the map, but when I generate an apk and install it, no map is shown, I've also tried both app-release and app-debug.

You can directly use the Maps services by using the Google Play Services library from the SDK importing and referring it to through the project properties. OR if you are using Android Studio, Just create your project with default Maps project.
Please see the following working code... You can copy and paste the files as it is:

Please Help me!!!!

try this :
class="com.google.android.gms.maps.SupportMapFragment"
on your activity :
SupportMapFragment mapfragment = (SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.showmap);

I think your problem in
android:name="com.google.android.gms.maps.MapFragment"
try instead of this, in the way:
class="com.google.android.gms.maps.MapFragment"
P.S. sometimes problem with maps is in not available Google Play Service on device.
(GooglePlayServicesUtil.isGooglePlayServicesAvailable(this) == ConnectionResult.SUCCESS)
must be true.
