地図プログラムを持っていて、エミュレータで実行すると正常に動作しますが、電話で実行すると白い画面になります。なぜですか? 多分私は間違っていますか？

コードは次のとおりです。

    package com.example.pi;


import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;

public class maps extends FragmentActivity
{
private GoogleMap map;

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

private void setupMap()
{
if (map == null)
{
map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.maps)).getMap();
if (map != null)
{
map.addMarker(new MarkerOptions().position(new LatLng(-7.795581, 110.376999)).title("Museum Batik Yogyakarta").snippet("Jl. Dr Sutomo 13 A RT 049 RW 12 Bausasran Danurejan Yogyakarta DIY"));
map.addMarker(new MarkerOptions().position(new LatLng(-8.504684, 115.25406)).title("The Blanco Renaissance Museum").snippet("Jalan Campuhan, Ubud"));
map.addMarker(new MarkerOptions().position(new LatLng(-6.176129, 106.822407)).title("Museum Nasional Indonesia").snippet("Jl. Medan Merdeka Barat 12, 10110, Indonesia"));
map.addMarker(new MarkerOptions().position(new LatLng(-6.9204314, 107.609893)).title("Museum Asia Afrika").snippet("Asia Afrika 65, Bandung 40111"));
map.addMarker(new MarkerOptions().position(new LatLng(-7.264724, 110.402201)).title("Museum Kereta Api Ambarawa").snippet("Jalan Stasiun 1, Ambarawa"));
map.addMarker(new MarkerOptions().position(new LatLng(-7.972623, 112.61953)).title("Museum Brawijaya").snippet("Jalan Ijen 25 A, Malang"));
map.addMarker(new MarkerOptions().position(new LatLng(-0.411769, 116.990318)).title("Museum Negeri Provinsi Kalimantan Timur Mulawarman").snippet("Jalan Diponegoro 26 Tenggarong Kelurahan Panji Kecamatan Tenggarong, Kutai Kartanegara"));
map.addMarker(new MarkerOptions().position(new LatLng(-8.591757, 116.085105)).title("Museum Negeri Propinsi Nusa Tenggara Barat").snippet("Jalan Panji Tilar Negara 6,  Mataram"));
map.addMarker(new MarkerOptions().position(new LatLng(-10.159336, 123.619366)).title("Museum Negeri Propinsi Nusa Tenggara Timur").snippet("Jalan El Tari  II Kota Baru, Kupang"));
map.addMarker(new MarkerOptions().position(new LatLng(-2.594777, 140.630955)).title("Museum Negeri Propinsi Papua").snippet("Jalan Raya Sentani Km 17.8 Wamena Kecamatan Abepura, Jayapura"));
map.addMarker(new MarkerOptions().position(new LatLng(-5.134677, 119.408587)).title("Museum Kota Makassar").snippet("Jalan Balai Kota 11 A Kelurahan Baru Kecamatan Ujung Pandang, Makassar 90111"));
map.addMarker(new MarkerOptions().position(new LatLng(3.567996, 98.696365)).title("Museum Negeri Propinsi Sumatera Utara").snippet("Jalan H.M. Joni 51 Teladan Barat, Medan 20217"));
map.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(-8.504684, 115.25406),3));
}
}

}

}

そしてここにマニフェストがあります：

最初に LogCat を開いて、何が起こっているかを確認する必要がありますが、通常、空の地図は、有効な Google Maps API キーを持っていないか、Google のデバッグ権限にコンピューターの SHA-1 コードを含めていないことを意味しますAPI コンソール。
