如何使用百度地图API

<application> <meta-data android:name="com.baidu.lbsapi.API_KEY" android:value="开发者 key" /> </application>

所需权限

<uses-permission android:name="android.permission.GET_ACCOUNTS" />  
<uses-permission android:name="android.permission.USE_CREDENTIALS" />  
<uses-permission android:name="android.permission.MANAGE_ACCOUNTS" />  
<uses-permission android:name="android.permission.AUTHENTICATE_ACCOUNTS" />  
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />  
<uses-permission android:name="android.permission.INTERNET" />  
<uses-permission android:name="com.android.launcher.permission.READ_SETTINGS" />  
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />  
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />  
<uses-permission android:name="android.permission.READ_PHONE_STATE" />  
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />  
<uses-permission android:name="android.permission.BROADCAST_STICKY" />  
<uses-permission android:name="android.permission.WRITE_SETTINGS" />  
<uses-permission android:name="android.permission.READ_PHONE_STATE" /> 
2、在xml布局中添加地图控件

<com.baidu.mapapi.map.MapView  
    android:id="@+id/bmapView"  
    android:layout_width="fill_parent"  
    android:layout_height="fill_parent"  
    android:clickable="true" />
?3、在应用程序创建时初始化，SDK引用的全局变量Context

SDKInitializer.initialize(getApplicationContext());，因此我们建议该方法放在Application的初始化方法中

public class MyApplication extends Application {
	@Override
	public void onCreate() {
		super.onCreate();
        //在使用SDK各组件之前初始化context信息，传入ApplicationContext 
		SDKInitializer.initialize(getApplicationContext());
		System.out.println("SDKInitializer一初始化");
	}
 
}

设置自定义的application为默认应用
  <application
        android:name="com.bao.ah.MyApplication"
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

public class MainActivity extends Activity {  
    @Override  
    protected void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);   
        //在使用SDK各组件之前初始化context信息，传入ApplicationContext  
        //注意该方法要再setContentView方法之前实现  
        //SDKInitializer.initialize(getApplicationContext());  
        setContentView(R.layout.activity_main);  
    }  
}

public class MainActivity extends Activity {  
    MapView mMapView = null;  
    @Override  
    protected void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);   
        //在使用SDK各组件之前初始化context信息，传入ApplicationContext  
        //注意该方法要再setContentView方法之前实现  
        //SDKInitializer.initialize(getApplicationContext());  
        setContentView(R.layout.activity_main);  
        //获取地图控件引用  
        mMapView = (MapView) findViewById(R.id.bmapView);  
    }  
    @Override  
    protected void onDestroy() {  
        super.onDestroy();  
        //在activity执行onDestroy时执行mMapView.onDestroy()，实现地图生命周期管理  
        mMapView.onDestroy();  
    }  
    @Override  
    protected void onResume() {  
        super.onResume();  
        //在activity执行onResume时执行mMapView. onResume ()，实现地图生命周期管理  
        mMapView.onResume();  
        }  
    @Override  
    protected void onPause() {  
        super.onPause();  
        //在activity执行onPause时执行mMapView. onPause ()，实现地图生命周期管理  
        mMapView.onPause();  
        }  
    }
