android设置打开蓝牙时报错:java.lang.SecurityException: Need android.permission.BLUETOOTH

我的手机是三星s10,Android12,遇到的这个问题,供参考

问题出现场景,我是最近在研究一下蓝牙相关的,找了文档学习但是触动mBluetoothAdapter.enable();开启或者打开蓝牙的时候就报了下面这个错:

开始解错:

表面提示就是需要许可证/就是权限之类的缺少，

然后我就顺着这个错误去网上查询资料是吧,就在清单文件里加了一堆蓝牙权限，

但是报错是依然的，后面在代码文件加了动态申请权限才解错ok:

重点来了:在初始化的代码里加上下面这个方法就不会报错了

    // todo 蓝牙动态申请权限
    private void initPermission(){
        if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.S){
            // Android 版本大于等于 Android12 时
            // 只包括蓝牙这部分的权限，其余的需要什么权限自己添加
            mPermissionList.add(Manifest.permission.BLUETOOTH_SCAN);
            mPermissionList.add(Manifest.permission.BLUETOOTH_ADVERTISE);
            mPermissionList.add(Manifest.permission.BLUETOOTH_CONNECT);
        } else {
            // Android 版本小于 Android12 及以下版本
            mPermissionList.add(Manifest.permission.ACCESS_COARSE_LOCATION);
            mPermissionList.add(Manifest.permission.ACCESS_FINE_LOCATION);
        }

        if(mPermissionList.size() > 0){
            ActivityCompat.requestPermissions(getActivity(),mPermissionList.toArray(new String[0]),1001);
        }
    }
