Android 搜索蓝牙相关设备权限声明及适配

确实需要获取位置信息的，还是需要声明Location相关权限

1. Android 12 及以上，仅需配置BLUETOOTH_SCAN，并声明android:usesPermissionFlags="neverForLocation"

2. Android 9(API 28) 以上，需要声明BLUETOOTH,BLUETOOTH_ADMIN及ACCESS_FINE_LOCATION，参考官方文档

3. Android 9(API 28) 及以下，可以声明ACCESS_COARSE_LOCATION或者ACCESS_FINE_LOCATION，推荐ACCESS_COARSE_LOCATION

综合起来，AndroidManifest文件为：

    <!-- Request legacy Bluetooth permissions on older devices. -->
    <uses-permission android:name="android.permission.BLUETOOTH"
        android:maxSdkVersion="30"/>
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN"
        android:maxSdkVersion="30"/>
<!--    安卓9及以下可以使用模糊定位-->
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"
        android:maxSdkVersion="28"/>
<!--    安卓10，11需要使用精准定位-->
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"
        tools:targetApi="q"
        android:maxSdkVersion="30"/>

    <!-- Needed only if your app looks for Bluetooth devices.
             You must add an attribute to this permission, or declare the
             ACCESS_FINE_LOCATION permission, depending on the results when you
             check location usage in your app. -->
<!--    安卓12及以上，不需要定位-->
    <uses-permission android:name="android.permission.BLUETOOTH_SCAN"
        android:usesPermissionFlags="neverForLocation"
        tools:targetApi="s" />

    <!-- Needed only if your app communicates with already-paired Bluetooth
         devices. -->
    <uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />
