这是java代码

package com.fakawangcx.tiebalogin;

import android.app.Activity;
import android.content.Context;
import android.hardware.camera2.CameraAccessException;
import android.hardware.camera2.CameraCharacteristics;
import android.hardware.camera2.CameraManager;
import android.os.Build;
import android.os.Bundle;
import android.webkit.CookieManager;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.TextView;
import android.widget.Toast;


public class MainActivity extends Activity {

    private WebView webView;
    private TextView cookieTextView;

    CameraManager cameraManager;



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        //相机特性
        cameraManager = (CameraManager) getSystemService(Context.CAMERA_SERVICE);
        try {
            CameraCharacteristics cameraCharacteristics = cameraManager.getCameraCharacteristics("1");
            Toast.makeText(this, "相机特性"+cameraCharacteristics, Toast.LENGTH_SHORT).show();
        } catch (CameraAccessException e) {
            throw new RuntimeException(e);
        }


        webView = findViewById(R.id.webView);
        cookieTextView = findViewById(R.id.cookieTextView);

        webView.clearCache(true);
        webView.getSettings().setJavaScriptEnabled(true);
        // 设置 WebView 的设置，允许加载网络图片并允许混合内容
        webView.getSettings().setBlockNetworkImage(false);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            webView.getSettings().setMixedContentMode(WebSettings.MIXED_CONTENT_ALWAYS_ALLOW);
        }


        // 加载百度贴吧登录页面
        webView.loadUrl("https://wappass.baidu.com/");



        // 设置WebViewClient监听页面加载
        webView.setWebViewClient(new WebViewClient() {

            @Override
            public void onPageFinished(WebView view, String url) {
                super.onPageFinished(view, url);
                // 判断登录完成
                if (url.contains("baidu")) {
                    CookieManager cookieManager = CookieManager.getInstance();
                    String cookies = cookieManager.getCookie(url);
                    cookieTextView.setText("Cookies: " + cookies);
                }

            }
        });

    }


}

看得出是获取相机详细信息出错，但是我不知道怎么改我的代码，代码很简单就是webview访问这个网页，但是网页要检查我的相机权限检测不到就一直在转
