Web view onReceivedError is handled but still showing web page not available

Question

I was trying to show a web page on my web view. and in case if an error occurs or page loading fails I want to show a sad smiley and a text showing that your page is not loaded

Answer 1

Because onReceivedError called before onPageFinished, so your sadSmiley and errorText gone.

Try below code,

boolean errorOccurred = false; // Global variable

webView.setWebViewClient(new WebViewClient() {
    @Override
    public void onPageStarted(WebView view, String url, Bitmap favicon) {
        super.onPageStarted(view, url, favicon);
        hideError();
        showProgress();
        Toast.makeText(Test.this, "start loading", Toast.LENGTH_SHORT).show();
        errorOccurred=false;
    }
    @Override
    public void onPageFinished(WebView view, String url) {
        super.onPageFinished(view, url);
        if (!errorOccurred) {
            hideError();
        }
        hideProgress();
        Toast.makeText(Test.this, "Web view was loaded", Toast.LENGTH_SHORT).show();
    }
    @Override
    public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
        errorOccurred = true;
        hideProgress();
        showError();
        Toast.makeText(Test.this, "Could not load your page", Toast.LENGTH_SHORT).show();
        super.onReceivedError(view, errorCode, description, failingUrl);
        Toast.makeText(Test.this, "error", Toast.LENGTH_SHORT).show();
    }
});
