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，文章来源：https://www.toymoban.com/news/detail-539453.html
<!-- 蓝牙权限 -->
<uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADVERTISE" />
<uses-permission android:name="BLUETOOTH_CONNECT" />
<!-- Required if your app derives physical location from Bluetooth
scan results. -->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />
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文章来源地址https://www.toymoban.com/news/detail-539453.html
// 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);
}
}
到了这里，关于android设置打开蓝牙时报错:java.lang.SecurityException: Need android.permission.BLUETOOTH_CONNECT permission的文章就介绍完了。如果您还想了解更多内容，请在右上角搜索TOY模板网以前的文章或继续浏览下面的相关文章，希望大家以后多多支持TOY模板网！
