Android 13 中如何处理蓝牙动态权限申请

在 Android 13 及以上版本中，蓝牙权限申请需要在运行时进行动态授权。以下是处理蓝牙动态权限申请的步骤：

1. 在 AndroidManifest.xml 文件中添加以下权限：

<uses-permission android:name='android.permission.BLUETOOTH'/>
<uses-permission android:name='android.permission.BLUETOOTH_ADMIN'/>
<uses-permission android:name='android.permission.ACCESS_FINE_LOCATION'/>

2. 在 Activity 或 Fragment 中，检查是否授权了蓝牙权限。如果没有授权，则请求权限。

private static final int REQUEST_ENABLE_BLUETOOTH = 1;
private static final int REQUEST_ENABLE_LOCATION = 2;

//检查蓝牙权限是否被授权
private boolean isBluetoothPermissionGranted() {
    return ActivityCompat.checkSelfPermission(this, Manifest.permission.BLUETOOTH) == PackageManager.PERMISSION_GRANTED &&
            ActivityCompat.checkSelfPermission(this, Manifest.permission.BLUETOOTH_ADMIN) == PackageManager.PERMISSION_GRANTED &&
            ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED;
}

//请求蓝牙权限
private void requestBluetoothPermission() {
    ActivityCompat.requestPermissions(this,
            new String[]{Manifest.permission.BLUETOOTH, Manifest.permission.BLUETOOTH_ADMIN, Manifest.permission.ACCESS_FINE_LOCATION},
            REQUEST_ENABLE_BLUETOOTH);
}

//处理权限请求的回调
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if (requestCode == REQUEST_ENABLE_BLUETOOTH) {
        if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            //权限被授予，执行相应操作
        } else {
            //权限被拒绝，提示用户
        }
    }
}

3. 如果需要访问设备位置，则还需要请求位置权限。在请求蓝牙权限时，同时请求位置权限。

//检查位置权限是否被授权
private boolean isLocationPermissionGranted() {
    return ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED;
}

//请求位置权限
private void requestLocationPermission() {
    ActivityCompat.requestPermissions(this,
            new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
            REQUEST_ENABLE_LOCATION);
}

//处理权限请求的回调
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if (requestCode == REQUEST_ENABLE_LOCATION) {
        if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            //权限被授予，执行相应操作
        } else {
            //权限被拒绝，提示用户
        }
    }
}

以上是 Android 13 中处理蓝牙动态权限申请的步骤。
