Como implementar a nova versão do Google Maps da API v2
Oi cada um eu vim a saber que o google maps tem preterido a sua versão anterior da API v1 e introduziu uma nova versão do google maps API v2. Eu tentei um exemplo, seguindo alguns links no google qualquer como eu tenho certeza que eu tenho a chave de api corretamente, fornecendo o código de hash chave exata e conseguiu obter a chave de api correta. Agora eu consegui escrever algum código também, mas quando eu tentei executar o código eu estou recebendo os erros por favor me ajude a resolver isso aqui é o meu código
e eu até tentei os códigos de amostra fornecidos pelo google play serviços um eu tenho o mesmo problema
esta é a amostra que eu fiz, referindo alguns links no google
classe de atividade principal
package com.example.apv;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.model.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;
import android.os.Bundle;
import android.app.Activity;
import android.app.FragmentManager;
public class MainActivity extends Activity
{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
FragmentManager fragmentManager = getFragmentManager();
MapFragment mapFragment = (MapFragment)fragmentManager.findFragmentById(R.id.map);
GoogleMap googleMap = mapFragment.getMap();
LatLng sfLatLng = new LatLng(37.7750, -122.4183);
googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
googleMap.addMarker(new MarkerOptions().position(sfLatLng).title("San Francisco")
.snippet("Population: 776733")
.icon(BitmapDescriptorFactory.defaultMarker(
BitmapDescriptorFactory.HUE_AZURE)));
googleMap.getUiSettings().setCompassEnabled(true);
googleMap.getUiSettings().setZoomControlsEnabled(true);
googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(sfLatLng, 10))
}
}
main.xml
<?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"

e finalmente meu arquivo de manifesto

Eu corro meu aplicativo no emulador da versão 4.2 e nível de API de 17 eu tenho seguinte erro

mais tarde eu vim a saber que esta versão não pode executar no emulador, então eu tentei executá-lo com dois dispositivos é um Sony xperia u da versão android 2.3.7 e Samsung Galaxy Tab da versão android 4.1.1 e estas são as minhas saídas
