在Android 10中，使用getNetworkSuggestions()方法需要您申请ACCESS_FINE_LOCATION权限。您需要首先动态地请求此权限，然后才能调用该方法。

以下是一段使用checkSelfPermission()和requestPermissions()方法来申请权限的代码示例：

if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
        != PackageManager.PERMISSION_GRANTED) {
    // Permission is not granted
    // Request the permission
    ActivityCompat.requestPermissions(this,
            new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
            MY_PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION);
} else {
    // Permission has already been granted
    // Call getNetworkSuggestions() method here
}

在您的Activity中处理权限请求的回调结果。如果用户授予了访问位置权限，然后再次调用getNetworkSuggestions()方法。

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION: {
            // If request is cancelled, the result arrays are empty.
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                // permission was granted
                // Call getNetworkSuggestions() method here
            } else {
                // permission denied
            }
            return;
        }
    }
}

在您的AndroidManifest.xml文件中，确保已添加ACCESS_FINE_LOCATION权限。

请注意，如果用户拒绝了访问位置权限，则可能需要使用其他方法来获取网络推荐列表。
