I would recommend using a chrome custom tab.
Here is a link to the docs
However, have just pasted the information you need here:
First, add chrome custom tabs to your Gradle file
dependencies {
...
compile 'com.android.support:customtabs:23.3.0'
}
Then create the chrome custom tab and show it:
// Use a CustomTabsIntent.Builder to configure CustomTabsIntent.
// Once ready, call CustomTabsIntent.Builder.build() to create a CustomTabsIntent
// and launch the desired Url with CustomTabsIntent.launchUrl()
String url = ¨https://paul.kinlan.me/¨;
CustomTabsIntent.Builder builder = new CustomTabsIntent.Builder();
CustomTabsIntent customTabsIntent = builder.build();
customTabsIntent.launchUrl(this, Uri.parse(url));
Im trying to find out how I add a custom offline page to my webview app. The app works well I just feel like a custom offline page would look much better! I have looked at some answers online but they dont seem to work any more :(. I hope someone can help!

Thank you!
Overrride the onReceivedError method and check internet connectivity inside it to confirm that the url failed because of the internet connectivity
#Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
if(!isappOnline()) {
webView.loadUrl("file:///android_asset/error.html");
}
}
private boolean isappOnline() {
ConnectivityManager cm = (ConnectivityManager)
getSystemService(Context.CONNECTIVITY_SERVICE);
return cm.getActiveNetworkInfo() != null;
}
also add your fallback page in assets folder src/main/assets/
I previously used Android Location Manager to retrieve location. However, when I run wikitude apps, the POIs are loaded but are not displayed.
