Google Map APIs Map Creating Error

Google Map APIs Map Creating Error - java

I created fragment in .xml file:
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
and I also init. GoogleMap and fragment objects in .java file:
private GoogleMap maps;
private View fragment1;
fragment1 = findViewById(R.id.map);
but When I was trying to create GoogleMap object
maps = ((MapFragment) getFragmentManager().findFragmentById(
R.id.map)).getMap();
I'm getting an error on getFragmentManager() eclipse couldn't find this method
How can I overcome this issue?

Make sure that your class extends FragmentActivity and your android project is google api project.

in Xml File
<?xml version="1.0" encoding="utf-8"?>
<fragment
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.google.android.gms.maps.SupportMapFragment"/>
and in Java File
SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
mMap = fm.getMap();
follow this tutorial
Google Map Using Fragment
in your manifest file
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<application>
...
<meta-data android:name="com.google.android.maps.v2.API_KEY"
android:value="HERE GOES YOUR API KEY" />
</application>

pls import the class , "import android.support.v4.app.FragmentActivity " Class in your main activity.
it can be imported if u have the google play service downloaded.

Check your manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.
android:versionCode="1"
android:versionName="1.0" >

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
Check your layout file:
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
Check your source file:
GoogleMap googleMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();

no need to extend FragmentActivity
try below code:
public class MainActivity extends Activity {
private GoogleMap googleMap;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Loading map
initilizeMap();
}
#Override
protected void onResume() {
super.onResume();
initilizeMap();
}
private void initilizeMap() {
if (googleMap == null) {
googleMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
if (googleMap == null) {
Toast.makeText(getApplicationContext(), "Sorry! unable to create maps",
Toast.LENGTH_SHORT).show();
}
}
}
}

Implement Google Places into Google Maps Using My Current Location

I have been researching everywhere and haven't found a concrete example of how to do this. I want to know how to send a HTTP request to Google to bring back data on places around my current location which is stored in LatLng? and then parse that data in JSON to then display on my map. Im new to android development so apologies if this question seems silly. I have looked through the Google documentation on this but I cant get my head around it :(
My MainActivity.Java file:
package com.example.mapapp;

import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.model.LatLng;
public class MainActivity extends FragmentActivity implements OnMyLocationChangeListener {
GoogleMap map;
LatLng myPosition;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
map.setMyLocationEnabled(true);
LocationManager locationmanager = (LocationManager) getSystemService(LOCATION_SERVICE);
Criteria criteria = new Criteria();
String provider = locationmanager.getBestProvider(criteria, true);
Location location = locationmanager.getLastKnownLocation(provider);
if(location!=null){
double latitude = location.getLatitude();
double longitude = location.getLongitude();
myPosition = new LatLng(latitude, longitude);

If you want to show places nearby, you need to use Google Places API.
You can read this tutorial about how to setup API project in your Google Developer Console.

Getting AdView to work

I am developing a game in libgdx. I read the official docs and tried to integrate MobClix Ads in my App but eclipse can't resolve this constructor for ADView class: (for Example):
AdView ad = new AdView(this, AdSize.BANNER, "a14d91b10f12454");
This line of code give me an error.
Maybe my import is not correct? I import this:
import com.google.android.gms.ads.AdSize;
import com.google.android.gms.ads.AdView;
And the same for:
adView.loadAd(new AdRequest());
I tried to search for an answer but I coudn't find, Does somone know how to resolve this?
Sorry for my poor english.

Put this code to mainactivity
import android.app.Activity;
import android.os.Bundle;
import com.startapp.android.publish.StartAppAd;
public class MainActivity extends Activity {
private StartAppAd add = new StartAppAd(this);
#Override
protected void onCreate(Bundle savedInstanceState) {

StartAppAd.init(this, "105158220", "205151606");
//StartAppSearch.init(this, "105158220", "205151606");
setContentView(R.layout.activity_main);
if(add.isReady())
{
add.showAd(); // show the ad
add.loadAd();
}
//a.loadAd(AdMode.FULLPAGE);
}
#Override

You can only view it in a phone.
What you see now is all you can get in the Emulator.

You're not asking for any of the gps permissions.
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
Also since you're using fake locations, you might want to include this one as well. I don't know if it's relevant in this case, but just in case.
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION"/>
Also, I know you said you're currently testing on a device, but for anyone who's curious about running google maps on an emulator (with the new Google Play dependency), it can be done this way.

Did you generate the API-Key with your debug-keystore or do you sign the application with a another keystore to build for the device? The API-Key is bind to a keystore and must be changed if you sign with another keystore or another debug-keystore on another developer-machine.

seems the guy who wrote about the permissions was right,
but I had the same problem and the solution was to correct the package name in the
internet site of google where you get the api key.
because I built at the same day another project with almost the same package name,
and forgot I produced the api key with that project,it didn't work for me with the second project.

Debug Error while running

I have tried with both solutions given for my previous problem which was giving me error in Google Map, the reason was I was mixing API1 and API2 code structure in my example, but after I got this reason of my problem I have again create 2 examples one for API1 and second for API2 but in any of example I had not got solution it can not run my application into tablet and gives me problem like:
"Application stopped unexpectedly.please try again".
So anybody can help me exacltly where I'm wrong, I'm going to put my whole code of API1 example and API2 example with this forum.

For the Google Maps API V2, for what I see now you are using the wrong Activity for your map layout. You are using the SupportMapFragment fragment, and there for you have to use the FragmentActivity object and not a simple Activity. try to change it to FragmentActivity.
And tell us what changed.

MapView not working [android]

i have a little trouble with the android mapview. It simply crashes every time i try to open the app!
Code:
package com.jappapps.android.travelbuddy;
import android.os.Bundle;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapView;
public class TravelBuddy extends MapActivity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main); // changed to lowercase
MapView mapView = (MapView) findViewById(R.id.mapview); // match id in main.xml
mapView.setBuiltInZoomControls(true);
}
#Override
protected boolean isRouteDisplayed() {
return false;
}

The <uses-library android:name="com.google.android.maps" /> line should be inside the <application> tags
