How to Enable Android Webview use New Window and Support Auth0 login
Android webview can support multiple browse windows, but it needs to be configured. Usually it can be done with the OncreateWindow method.
The multiple window feature is important if your webview needs open another window or wants use google,Facebook etc Logins, called Auth0. If webview doesn’t support multiple windows, these logins can fail and window invoking links may not respond (but this unresponsive links can be fixed by disabling the multiple window support).
So here is an example for letting the webview open multiple window easily, this code should be placed under the WebChromeClient method.
First, add these options in your activity’s main webview, adding this will allow webview to use multiple windows:
WebSettings webSettings = webview.getSettings(); webSettings.setJavaScriptEnabled(true); webview.getSettings().setJavaScriptCanOpenWindowsAutomatically(true); webSettings.setSupportMultipleWindows(true);
Secondly, add these above Oncreate method in your webview Activity:
private WebView mWebviewPop;
private AlertDialog dialog;
private AlertDialog builder;
private static final String uanormal = "Mozilla/5.0 (Linux; U; Android 2.3.3; en-gb; " +
"Nexus S Build/GRI20) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1";
Note: The string uanormal is used here and it is a custom useragent, because if it is not used, the google login will fail because of the disallowed useragent.
Next,in your webchrome client method, add this:
Webview.setWebChromeClient(new WebChromeClient() {
@Override
public boolean onCreateWindow(WebView view, boolean isDialog,
boolean isUserGesture, Message resultMsg) {
mWebviewPop = new WebView(getApplicationContext());
mWebviewPop.setWebChromeClient(new WebChromeClient());
mWebviewPop.getSettings().setJavaScriptEnabled(true);
mWebviewPop.getSettings().setSavePassword(true);
mWebviewPop.getSettings().setSaveFormData(true);
mWebviewPop.getSettings().setUserAgentString(uanormal);
mWebviewPop.setVerticalScrollBarEnabled(false);
mWebviewPop.setHorizontalScrollBarEnabled(false);
mWebviewPop.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url == null || url.startsWith("http://") || url.startsWith("https://"))
return false;
try {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
view.getContext().startActivity(intent);
return true;
} catch (Exception e) {
// Log.i(TAG, "shouldOverrideUrlLoading Exception:" + e);
return true;
}
}
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
dialog = new AlertDialog.Builder(Webactivity.this, AlertDialog.THEME_DEVICE_DEFAULT_LIGHT).create();
dialog.setMessage("Please wait...");
dialog.setTitle("Loading..");
dialog.setIcon(R.drawable.yourimage);
dialog.show();
}
@Override
public void onPageFinished(WebView view, String url) {
// Page loading finished
dialog.dismiss();
}});
builder = new AlertDialog.Builder(YourActivity.this, AlertDialog.THEME_DEVICE_DEFAULT_LIGHT).create();
builder.setView(mWebviewPop);
builder.setButton("Close", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int id) {
mWebviewPop.destroy();
dialog.dismiss();
}
});
builder.show();
builder.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);
CookieManager cookieManager = CookieManager.getInstance();
cookieManager.setAcceptCookie(true);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
cookieManager.setAcceptThirdPartyCookies(mWebviewPop, true);
}
WebView.WebViewTransport transport = (WebView.WebViewTransport) resultMsg.obj;
transport.setWebView(mWebviewPop);
resultMsg.sendToTarget();
return true;
}
@Override
public void onCloseWindow(WebView window) {
//Toast.makeText(mContext,"onCloseWindow called",Toast.LENGTH_SHORT).show();
try {
mWebviewPop.destroy();
} catch (Exception e) {
}
try {
builder.dismiss();
} catch (Exception k) {
}
}
