com.ycbjie.webviewlib.view.X5WebViewActivity闪退

[Iridescentangle]

release版本:1.4.0

项目中将该Activity注册了Intent-Filter，所以应用接入后，会出现在浏览器应用列表里，

<intent-filter tools:ignore="AppLinkUrlError" >
    <action android:name="android.intent.action.VIEW" />

    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
    <!-- 使用http，则只能打开http开头的网页 -->
    <data android:scheme="https" />
</intent-filter>

但是这个Activity中的WebProgress报了空指针

private void initFindViewById() {
      webView = findViewById(R.id.web_view);
      pb = findViewById(R.id.progress);
      tvTitle = findViewById(R.id.tv_title);
      mTitleToolBar = findViewById(R.id.title_tool_bar);
      //显示进度条
      pb.show();
      //设置进度条过度颜色
      pb.setColor(Color.BLUE,Color.RED);
      //设置单色进度条
      pb.setColor(Color.BLUE);
}
