This is how i am using in my app private class MyWebChromeClient extends WebChromeClient { //The undocumented magic method override //Eclipse will swear at you if you try to put @Override here // For Android 3.0+ public void openFileChooser(ValueCallback uploadMsg, String acceptType) { mUploadMessage = uploadMsg; Intent intent = new Intent(Intent.ACTION_GET_CONTENT); intent.addCategory(Intent.CATEGORY_OPENABLE); intent.setType(“*/*”); startActivityForResult(Intent.createChooser(intent, “File … Read more

Android- Webview onPageFinished Called Twice

If the url is OK after onPageStarted method starts onPageFinished, but if the url is redirected after onPageStarted starts shouldOverrideUrlLoading and then onPageFinished. You should just check if the loading URL is redirected or not private boolean isRedirected; @Override public void onPageStarted(WebView view, String url, Bitmap favicon) { if (!isRedirected) { //Do something you want … Read more

Letting WebView on Android work with prefers-color-scheme: dark

by

UPDATE 2022: AndroidX Webkit 1.5.0 fixed a lot of the quirkyness of how webview handles dark mode. For this to work you need to: Add the latest version of webkit to your project (at least 1.5.0): implementation ‘androidx.webkit:webkit:1.5.0’ Set the target version of your application to 33 or up targetSdkVersion 33 Make sure Android System … Read more

handling links in a webview

I assume you are already overriding shouldOverrideUrlLoading, you just need to handle this special case. mWebClient = new WebViewClient(){ @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { if(url.startsWith(“mailto:”)){ MailTo mt = MailTo.parse(url); Intent i = newEmailIntent(MyActivity.this, mt.getTo(), mt.getSubject(), mt.getBody(), mt.getCc()); startActivity(i); view.reload(); return true; } else{ view.loadUrl(url); } return true; } }; mWebView.setWebViewClient(mWebClient); public static … Read more

Android webview loading data performance very slow

by

I think the following works best: if (Build.VERSION.SDK_INT >= 19) { webView.setLayerType(View.LAYER_TYPE_HARDWARE, null); } else { webView.setLayerType(View.LAYER_TYPE_SOFTWARE, null); } Android 19 has Chromium engine for WebView. I guess it works better with hardware acceleration. For more info Android 4.4 KitKat, the browser and the Chrome WebView Hardware Acceleration also do’s the trick.You can use it … Read more
