Question

当我将我的https网址加载到android中的webview时，我在logcat中得到了错误，如下所示

E/chromium: [ERROR:ssl_client_socket_impl.cc(1141)] handshake failed; returned -1, SSL error code 1, net_error -101

由于这个CSS和JS没有正确加载到webview中。

我已经完成了这个link。但是，当我第二次加载相同的URL时，它正常工作。我使用的是Android 5.0。

请帮助我解决这个问题。

在您设置的Webview客户端方法中

同样的错误发生在我身上，我是这样解决的。请看一下。

webViewClient = object : WebViewClient() {
      override fun onReceivedSslError(
        view: WebView?,
        handler: SslErrorHandler?,
        error: SslError?
      ) {
        showSSLErrorDialog(handler)
      }
    }

//下面是错误处理对话框

  private fun showSSLErrorDialog(handler: SslErrorHandler?) {

val builder = AlertDialog.Builder(this@MainActivity)
builder.setTitle("APP NAME")
builder.setMessage("SOME THING WRONG")
builder.setPositiveButton("YES"){dialog, which ->
            // Do something when user press the positive button
           handler?.proceed()   

//do some other things

      
        }
builder.setNegativeButton("No"){dialog,which ->
           handler?.cancel()
//do some other things
        }
val dialog: AlertDialog = builder.create()
        dialog.show()

  }
