Já coloquei o projeto google_play_service_lib, gerei a chave e coloquei no meu android manifest, coloquei as permissões necessárias e nada funciona, testei no emulador 4.4, tentei no meu celular, mais todos param e fecham a aplicação. Fiz tudo como mostrou no vídeo, não consigo exibir o mapa o que pode ser???
Você entrou no Console do Google e criou o seu projeto lá com a chave que você gerou ?
Sim, criei
Ah um detalhe, no console do Google não aparece a opção Google Maps V2 como aparece na vídeo aula, só aparece Google Maps, eu ativei essa opção.
Vou colocar aqui o código do meu Android Manifest para ver se pode ser algum erro lá, se está faltando alguma permissão.

Beleza, posta aqui o seu Manifest e o Log quando o app quebra por favor

Oi pessoal,
quando forem colocar trechos de código, usem três crases: ```. Vocês estavam usando três aspas: '''
Então é só fazer assim:

Você pode postar o Log com o erro ao tentar executar o app ?

You must have the following declaration within the <application> element:

</manifest>Você só tinha esquecido um @ antes do integer no seu meta-data. ;)
Realmente como não vi a falta desse @, coloquei e sai desse erro e esbarrei em outro. Parece que está gerando erro no Zoom, comentei o método e testei no celular finalmente abriu a tela, porém o mapa não abriu.

Uma forma de resolver isso é alterar seu método centralizar para dar zoom somente a partir do momento em que o mapa estiver pronto para ser usado, assim:
public void centralizar(final LatLng local){
getMapAsync(new OnMapReadyCallback() {
@Override
public void onMapReady(GoogleMap googleMap) {
//esse googleMap é o mesmo que você teria se chamasse o getMap
googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(local, 17));
}
});
}Eu fiz as alterações, porém o mapa continua sem abrir, mais agora não gera mais erro no logcat
Pode ser por que na vídeo aula aparece para ativar a chave Google Maps V2 e no site do Google só é possível ativar a Google Maps Api?
