一、 申请API_KEY
1. http://lbsyun.baidu.com/ :在这里注册并申请。注册之后出现应用列表，选择 创建应用 ：
创建应用
2. 创建应用后如下图所示：
选择
- 应用类型选择的话，我们选择 Android SDK 就可以了。
SHA1
PS：SHA1找了我好久...
- SHA1寻找之路：
左侧选择项目目录类型 project ，打开右侧 Gradle > app > android > signingReport ，点击发现空白，突然发现左下角有个转换的键（左下标红的地方），答案出来了。
3. 获取基本参数
- 创建完成，获得
API_KEY。
二、 下载百度定位SDK
- 如无特殊要求，选择基础功能即可：
- 下载开发包解压后得到 libs 文件夹。
- BaiduLBS_android.jar 放在 project 目录下的 app > libs 目录下，其他so库放在 app > main > 新建文件夹jniLibs 下，或者都可以放jniLibs下。
三、 使用百度地图
1. 在 AndroidManifest.xml 中添加如下权限：
- 在
Application标签中声明SERVICE组件,每个APP拥有自己单独的定位SERVICE：
- 百度定位SDK在4.2版本之后需要在 AndroidMainfest.xml 中正确设置
Accesskey（AK），如果设置错误将会导致定位和地理围栏服务无法正常使用。设置AK，在Application标签中加入：
2. 新建LBSwithBaidu，LBSwithBaidu代码如下：
public class LBSwithBaidu extends AppCompatActivity {
private TextView text;
private LocationClient client;
private StringBuilder connrentPosition;
private MapView map;
private BaiduMap baidumap;
private boolean ismylocation=true;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//SDK的初始化
SDKInitializer.initialize(getApplicationContext());
//注册客户端定位的监听
client = new LocationClient(getApplicationContext());
client.registerLocationListener(new MylocationListener());
setContentView(R.layout.activity_lbswith_baidu);
text= (TextView) findViewById(R.id.textView_location);
//获取地图控件的引用
map= (MapView) findViewById(R.id.mapwithbaidu);
//获取地图实例
baidumap=map.getMap();
//设置是否在地图上显示位置
baidumap.setMyLocationEnabled(true);
//6.0以上动态权限的获取
List permission = new ArrayList<>();
if (ContextCompat.checkSelfPermission(LBSwithBaidu.this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

}
