导入库文件
在下载页面下载最新的库文件。将liblocSDK2.4.so文件拷贝到libs/armeabi目录下。将locSDK2.4.jar文件拷贝到工程根目录下，并在工程属性->Java Build Path->Libraries中选择“Add JARs”，选定locSDK2.4.jar，确定后返回。这样您就可以在程序中使用百度定位API了。
设置AndroidManifest.xml
为区分2.3版本service，需要将manifest file中的 intent filter声明为com.baidu.location.service_v2.4 在application标签中声明service组件
1. <service android:name="com.baidu.location.f" android:enabled="true" android:process=":remote"
2. android:permission="android.permission.BAIDU_LOCATION_SERVICE">
3. <intent-filter>
4. <action android:name="com.baidu.location.service_v2.4"></action>
5. </intent-filter>
6. </service>
声明使用权限
1. <permission android:name="android.permission.BAIDU_LOCATION_SERVICE"></permission>
2. <uses-permission android:name="android.permission.BAIDU_LOCATION_SERVICE"></uses-permission>
3. <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>
4. <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
5. <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>
6. <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
7. <uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>
8. <uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
9. <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
10. <uses-permission android:name="android.permission.INTERNET" />
11. <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"></uses-permission>
12. <uses-permission android:name="android.permission.READ_LOGS"></uses-permission>

功能类的使用
初始化LocationClient类
此处需要注意：LocationClient类必须在主线程中声明。需要Context类型的参数。
1. public LocationClient mLocationClient
=
null
;
2. public BDLocationListener myListener
=
new MyLocationListener
(
)
;
3.
4. public
void onCreate
(
)
{
5. =
new LocationClient
(
this
)
;
//声明LocationClient类
6. registerLocationListener
( myListener
)
;
//注册监听函数
7. }
实现BDLocationListener接口
BDLocationListener接口有2个方法需要实现：
1.接收异步返回的定位结果，参数是BDLocation类型参数。
2.接收异步返回的POI查询结果，参数是BDLocation类型参数。
1. public
class MyLocationListenner
implements BDLocationListener
{
2.
@Override
3. public
void onReceiveLocation
(BDLocation location
)
{
4. if
(location
==
null
)
5. return
;
6.
StringBuffer sb
=
new
StringBuffer
(
256
)
;
7. append
(
"time : "
)
;
8. append
(location.
getTime
(
)
)
;
9. append
(
"\nerror code : "
)
;
10. append
(location.
getLocType
(

)
;
11. append
(
"\nlatitude : "
)
;
12. append
(location.

(

)
;
13. append
(
"\nlontitude : "
)
;
14. append
(location.
getLongitude
(
)
)
;
15. append
(
"\nradius : "
)
;
16. append
(location.
getRadius
(
)
)
;
17. if
(location.
getLocType
(
)
== BDLocation.
TypeGpsLocation
)
{
18. append
(

;
19. append

;
20. append

22. }
else
if
(location.
getLocType
(
)
== BDLocation.
TypeNetWorkLocation
)
{
23. append
(
"\naddr : "
)
;
24. append
(location.
getAddrStr
(
)
)
;
25. }
26.
27. (sb.
toString
(
)
)
;
28. }
29. public
void onReceivePoi
(BDLocation poiLocation
)
{
30. if
(poiLocation
==
null
)
{
31. return
;
32. }
33.
StringBuffer sb
=
new
StringBuffer
(
256
)
;
34. append
(
"Poi time : "
)
;
35. append
(poiLocation.
getTime
(
)
)
;
36. append
(
"\nerror code : "
)
;
37. append
(poiLocation.
getLocType
(
)
)
;
38. append
(
"\nlatitude : "
)
;
39. append
(poiLocation.
getLatitude
(
)
)
;
40. append
(
"\nlontitude : "
)
;
41. append
(poiLocation.

(

)
;
42. append
(

46. append

47. }
48. if
(poiLocation.
hasPoi
(

)
{
49. append
(
"\nPoi:"
)
;
50. append
(poiLocation.
getPoi
(

)
;
51. }
else
{
52. append
(
"noPoi information"
)
;
53. }
54. (sb.
toString
(
)
)
;
55. }
56. }
设置参数
设置定位参数包括：定位模式（单次定位，定时定位），返回坐标类型，是否打开GPS等等。eg：
1. =
new LocationClientOption
(
)
;
2. setOpenGps
(
true
)
;
3. setAddrType
(
"detail"
)
;
4. setCoorType
(
"gcj02"
)
;
5. setScanSpan
(
5000
)
;
6. disableCache
(
true
)
;
//禁止启用缓存定位
7. setPoiNumber
(
5
)
;
//最多返回POI个数
8. setPoiDistance
(
1000
)
;
//poi查询距离
9. setPoiExtraInfo
(
true
)
;
//是否需要POI的电话和地址等详细信息
10. setLocOption
(option
)
;
发起定位请求
发起定位请求。请求过程是异步的，定位结果在上面的监听函数onReceiveLocation中获取。
1. if
(mLocClient
!=
null
&& mLocClient.
isStarted
(
)
)
2. requestLocation
(
)
;
3. else
4. d
(
"LocSDK_2.0_Demo1",
"locClient is null or not started"
)
;
发起POI查询请求
发起POI查询请求。请求过程是异步的，定位结果在上面的监听函数onReceivePoi中获取。
1. if
(mLocClient
!=
null
&& mLocClient.
isStarted
(
)
)
2. requestPoi
(
)
;
位置提醒使用
位置提醒最多提醒3次，3次过后将不再提醒。 假如需要再次提醒，或者要修改提醒点坐标，都可通过函数SetNotifyLocation()来实现。
1. //位置提醒相关代码
2. =
new NotifyLister
(
)
;
3. SetNotifyLocation
(
42.03249652949337,
113.3129895882556,
3000,
"gps"
)
;
//4个参数代表要位置提醒的点的坐标，具体含义依次为：纬度，经度，距离范围，坐标系类型(gcj02,gps,bd09,bd09ll)
4. registerNotify
(mNotifyer
)
;
5. //注册位置提醒监听事件后，可以通过SetNotifyLocation 来修改位置提醒设置，修改后立刻生效。
1. //BDNotifyListner实现
2. public
class NotifyLister
extends BDNotifyListener
{
3. public
void onNotify
(BDLocation mlocation,
float distance
)
{
4. vibrate
(
1000
)
;
//振动提醒已到设定位置附近
5. }
6. }
1. //取消位置提醒
2. removeNotifyEvent
(mNotifyer
)
;
