我的步骤:
- 从 debug.keystore 获得 SHA1 代码
- 在 google apis 控制台中创建应用程序
- 启用谷歌地图 api v2
- 输入 SHA1;my.package.name
- 获取 API 密钥
创建 AndroidManifest 文件:
<permission android:name="my.package.name.permission.MAPS_RECEIVE" android:protectionLevel="signature"/> <uses-permission android:name="my.package.name.permission.MAPS_RECEIVE"/> <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="15"/> <uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" /> <uses-feature android:glEsVersion="0x00020000" android:required="true"/> <application android:label="@string/app_name" android:icon="@drawable/ic_launcher" android:hardwareAccelerated="true"> <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="MY_API_KEY_HERE" /> <activity android:name="MyActivity" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN"/> <category android:name="android.intent.category.LAUNCHER"/> </intent-filter> </activity> </application> </manifest>
创建的布局
- 将“google-play-services.jar”放入库
编译后我崩溃了:

之后,我将布局更改为:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent" />
并将 MyActivity 更改为
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
FragmentManager manager = getFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
transaction.add(R.id.map, MapFragment.newInstance());
transaction.commit();
结果,应用程序启动了,但我没有看到地图。
控制台日志:
ERROR/Google Maps Android API(10369): Authorization failure.
