提问by antedesk
Today I tried to use google maps api v2 for Android 2.3.3 My steps:
今天我尝试使用谷歌地图 api v2 for Android 2.3.3 我的步骤：
- got SHA1 code from debug.keystore
- create a new project in google apis console
- register a new id
- enabled google maps android api v2
- create an android key using as input SHA1;it.mappe (it.mappe is my package)
- get API key
update AndroidManifest file:
<permission android:name="it.mappe.permission.MAPS_RECEIVE" android:protectionLevel="signature" /> <uses-permission android:name="it.mappe.permission.MAPS_RECEIVE" /> <uses-sdk android:minSdkVersion="10" android:targetSdkVersion="16" /> <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:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="MY_KEY" /> <activity android:name="it.mappe.MainActivity" 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>my main activity
public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); }my activity_main:
<fragment xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/map" android:layout_width="match_parent" android:layout_height="match_parent" class="com.google.android.gms.maps.SupportMapFragment"/>copy directory

- 从 debug.keystore 得到 SHA1 代码
- 在 google apis 控制台中创建一个新项目
- 注册一个新的id
- 启用谷歌地图 android api v2
- 使用作为输入 SHA1;it.mappe 创建一个 android 密钥（it.mappe 是我的包）
- 获取 API 密钥
更新 AndroidManifest 文件：
<permission android:name="it.mappe.permission.MAPS_RECEIVE" android:protectionLevel="signature" /> <uses-permission android:name="it.mappe.permission.MAPS_RECEIVE" /> <uses-sdk android:minSdkVersion="10" android:targetSdkVersion="16" /> <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:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="MY_KEY" /> <activity android:name="it.mappe.MainActivity" 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>我的主要活动
public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); }我的活动_主要：
<fragment xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/map" android:layout_width="match_parent" android:layout_height="match_parent" class="com.google.android.gms.maps.SupportMapFragment"/>将目录复制
ANDROID_SDK_DIR/extras/google/google_play_services/libproject/google-play-services_lib到项目的根目录添加
/extras/android/compatibility/v4/android-support-v4.jar为外部 jar将下一行添加到

<fragment>should be in all lowercase.
<fragment>应该全部小写。
Also, you are using Activity(not FragmentActivity) with SupportMapFragment, and I doubt that combination will work.
此外，您正在使用Activity(not FragmentActivity) with SupportMapFragment，我怀疑这种组合是否有效。

Check if the target Google SDK version in the project.properties and the support lib(Android.jar) versions are the same.
检查 project.properties 中的目标 Google SDK 版本和支持的 lib(Android.jar) 版本是否相同。
