所有权限放到AndroidManifest.xml里

 <!-- 这个权限用于进行网络定位-->
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>
    <!-- 这个权限用于访问GPS定位-->
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
    <!-- 用于访问wifi网络信息，wifi信息会用于进行网络定位-->
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>
    <!-- 获取运营商信息，用于支持提供运营商信息相关的接口-->
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
    <!-- 这个权限用于获取wifi的获取权限，wifi信息会用来进行网络定位-->
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>
    <!-- 用于读取手机当前的状态-->
    <uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
    <!-- 写入扩展存储，向扩展卡写入数据，用于写入离线定位数据-->
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
    <!-- 访问网络，网络定位需要上网-->
    <uses-permission android:name="android.permission.INTERNET" />
    <!-- SD卡读取权限，用户写入离线定位数据-->
    <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"></uses-permission>

    <uses-permission android:name="com.android.launcher.permission.READ_SETTINGS" />
    <uses-permission android:name="android.permission.WAKE_LOCK"/>
    <uses-permission android:name="android.permission.GET_TASKS" />
    <uses-permission android:name="android.permission.WRITE_SETTINGS" />

放到AndroidManifest.xml的 application里边就行啦

 <service android:name="com.baidu.location.f" android:enabled="true" android:process=":remote">
        </service>
        <meta-data
            android:name="com.baidu.lbsapi.API_KEY"
            android:value="ugEXhO2214IxgfIymSG7uHLeZIbQ0WLu" />       //key:开发者申请的Key
