Google Maps API v2 can't display a map

Question

I'm new on Stackoverflow. I have a problem with displaing a map on new Google Maps API v2. I done all the steps from this page https://developers.google.com/maps/documentation/android/start?hl=pl ans some tutorials and i can't display the map. When i run my application, on emulator displays only magnification controls and rest screen is white and i can't open it on my real device (HTC Wildfire S- android 2.3.5). I added google_play_service_lib into my project too. I was looking for answer for my problem on a lot of pages and in a lot of tutorials but i don't found it! Please help me!

It's my Manifest file:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.adrianspora.googlemaptest"
    android:versionCode="1"

    <uses-sdk

</manifest>

There's code of MainActivity:

package com.adrianspora.googlemaptest;

import com.google.android.gms.maps.MapFragment;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

    }

    @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;
    }

}

And it's main layout's code:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >


<fragment 
          android:id="@+id/map"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:name="com.google.android.gms.maps.MapFragment"/>

</LinearLayout>

There is a list of logs displays in LogCat :

Answer 1

I had the same error and tried like 6 tutorials, and read all the documentation from google. And finnally I've got it running and displaying the map. This is how it works for me.

1.Remove the libraries google-play-services and android support-v4 from both your eclipse and your PC. 2.Download again it from de sdk-manager. 3.Follow the instructions [here] (https://developers.google.com/maps/documentation/android/intro#sample_code) go to Sample Code and do as it says. Check specially this Existing Android Code Into Workspace , do not import the libraries as projects, they won't work. 4.Change all your MapFragment for SupportMapFragment, don't foget to extend your Actvity to FragmentActivity (that was my fail). 5.Disable (if it is enabled) the build automatically option from your project. 6.Clean the project. 5.Enable the build automatically option.

It should work.

Answer 2

You have to use FragmentActivity

public class PlacesMapActivity extends android.support.v4.app.FragmentActivity
    implements OnClickListener, LocationListener {

ImageButton btn_home;
private GoogleMap mMap;


protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_map);

    SupportMapFragment fragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
    mMap = fragment.getMap();
    mMap.setMyLocationEnabled(true);

    // mMap = ((SupportMapFragment) getSupportFragmentManager()
    // .findFragmentById(R.id.map)).getMap();

    MarkerOptions markerOptions = new MarkerOptions();
    markerOptions.title("First Location");
    markerOptions.snippet("This Is Test Location");

    LatLng latlng = new LatLng(23.0333, 72.6167);

    markerOptions.position(latlng);
    // markerOptions.title("Ahmedabad Cordinat Found here");

    // Marker m = mMap.addMarker(markerOptions);

    mMap.setInfoWindowAdapter(new InfoWindowAdapter() {

        @Override
        public View getInfoWindow(Marker arg0) {

            return null;
        }

        @Override
        public View getInfoContents(Marker marker) {

            View myContentView = getLayoutInflater().inflate(
                    R.layout.custommarker, null);
            TextView tvTitle = ((TextView) myContentView
                    .findViewById(R.id.title));
            tvTitle.setText(marker.getTitle());
            TextView tvSnippet = ((TextView) myContentView
                    .findViewById(R.id.snippet));
            tvSnippet.setText(marker.getSnippet());
            return myContentView;

        }
    });

    mMap.addMarker(new MarkerOptions()
            .position(latlng)
            .title("This is Sabarmati Ashram")
            .snippet("Ahmedabad")
              .icon(BitmapDescriptorFactory                     .defaultMarker(BitmapDescriptorFactory.HUE_RED)));

    mMap.setOnInfoWindowClickListener(new OnInfoWindowClickListener() {

        @Override
        public void onInfoWindowClick(Marker arg0) {
            // TODO Auto-generated method stub
            Intent intent = new Intent(getBaseContext(),
                    DetailsOfPlacesActivity.class);
            startActivity(intent);
        }
    });

    btn_home = (ImageButton) findViewById(R.id.activity_map_ibtn_home);
    btn_home.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            finish();
        }
    });
}

Answer 3

You should use Support Fragment since your min sdk is 8.

https://developers.google.com/maps/documentation/android/reference/com/google/android/gms/maps/SupportMapFragment

<fragment
class="com.google.android.gms.maps.SupportMapFragment"
android:id="@+id/map"  
android:layout_width="match_parent"
android:layout_height="match_parent"/>

Your activity must extend FragmentActivity and to initialize GoogleMap object use the below.

SupportMapFragment fm = (SupportMapFragment)  getSupportFragmentManager().findFragmentById(R.id.map);
GoogleMap mMap = fm.getMap(); 

Make sure you have added support library

Also make sure you imported the below

import android.support.v4.app.FragmentActivity;  
import com.google.android.gms.maps.SupportMapFragment;    

Check if you have enabled maps for android in google api console under services tab.

Check if you have followed all the steps mentioned in the docs

https://developers.google.com/maps/documentation/android/start

You can also check a similar question i answered.

App shows grid screen instead of google map

When i run my application, on emulator displays only magnification controls and rest screen is white

You should test it on a real device.

Answer 4

What kind of API-key are you using? You should alway use a dev-key when programming and your app needs to be registered in the Google APIs Console.

And you have to add the google-play-services-library at Preferences/Android, NOT at Preferences/Java Build Path.

Answer 5

You should use SupportMapFragment, since your API level is 2.3.5

Replace your fragment in the XML with:

    <fragment
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    class="com.google.android.gms.maps.SupportMapFragment" />

and also import this class in the Java file, instead of MapFragment.

Also, as a general advice, you should use the Support library if you want to support pre-Honeycomb devices and use fragments, etc.
