So I found some code (How to call admob Interstitial ad from android webview JavascriptInterface) that allows the use of javascript on a webview page to activate within the app.
Now The issue I'm having is when the button is pressed, it toasts that the Ad hasn't loaded. Why isn't it loading the ad?
Here is the full code used in the MainActivity.java

import android.content.DialogInterface;
import android.graphics.Bitmap;

public class MainActivity extends AppCompatActivity {

WebView ProfOak;
String URL;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
AdView mAdView = findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().build();
mAdView.loadAd(adRequest);
URL = "http://url-here";
ProfOak = findViewById(R.id.ProfOak);
ProfOak.getSettings().setJavaScriptEnabled(true);
ProfOak.getSettings().setDomStorageEnabled(true);
ProfOak.getSettings().setUseWideViewPort(true);
ProfOak.setWebChromeClient(new WebChromeClient());
ProfOak.addJavascriptInterface(new WebAppInterface(this), "Android");
ProfOak.setVerticalScrollBarEnabled(false);

try {
ProfOak.stopLoading();
} catch (Exception e) {
}
if (ProfOak.canGoBack()) {
ProfOak.goBack();
}
ProfOak.loadUrl("about:blank");
AlertDialog alertDialog = new AlertDialog.Builder(MainActivity.this).create();
alertDialog.setTitle("Connection Required");
alertDialog.setMessage("This app requires an active Internet Connection to communicate with the Database.");
alertDialog.setButton(DialogInterface.BUTTON_POSITIVE, "Try Again", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
finish();
startActivity(getIntent());
}
});
alertDialog.show();
super.onReceivedError(ProfOak, errorCode, description, failingUrl);
}
});
mInterstitialAd = new InterstitialAd(this);
mInterstitialAd.setAdUnitId("ca-app-pub-3940256099942544/5224354917");
mInterstitialAd.loadAd(new AdRequest.Builder().build());
mInterstitialAd.setAdListener(new AdListener(){
#Override
public void onAdLoaded(){
}
#Override
public void onAdClosed() {
// Load the next interstitial.
mInterstitialAd.loadAd(new AdRequest.Builder().build());
}
});
}
public void displayLoadedAd(){
runOnUiThread(new Runnable() {
public void run() {
if (mInterstitialAd.isLoaded()) {
mInterstitialAd.show();
mInterstitialAd.loadAd(new AdRequest.Builder().build());
}
else
Toast.makeText(getApplicationContext(), "Ad not loded", Toast.LENGTH_SHORT).show();
}
});
}
public class WebAppInterface {
Context mContext;
/** Instantiate the interface and set the context */
WebAppInterface(Context c) {
mContext = c;
}
#JavascriptInterface
public void showAdFromJs(){
Toast.makeText(mContext, "Loading Ad", Toast.LENGTH_SHORT).show();
displayLoadedAd();
}
}
public class myWebClient extends WebViewClient
{
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
//Controlling navigation
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_DOWN) {
switch (keyCode) {

if (ProfOak.canGoBack()) {
ProfOak.goBack();
}
else {
finish();
}
return true;
}
}
return super.onKeyDown(keyCode, event);
}
}
This is what i have in the webview URL
<input class="button" type="button" value="Ignore this" onclick="myFunction()">
<script type="text/javascript">
function myFunction() { Android.showAdFromJs(); };
</script>
It seems that you are using ad-unit id for rewarded video i.e
ca-app-pub-3940256099942544/5224354917.
For Interstitial the test ad unit id is
ca-app-pub-3940256099942544/1033173712. Refer to https://developers.google.com/admob/android/test-ads

Progressbar is loading very fine at first time when main page loads. after that it disappear.
Use
progressBar.setVisibility(View.VISIBLE);
in onPageStarted method

The progress bar and webview works fine but when the page is finished loading the progress bar still remains? When I have loaded the page the progress bar visibility doesn't dissapear/change to GONE? Where is the error?
Ive tried both progressBar.setVisibility(View.INVISIBLE) and progressBar.setVisibility(View.GONE); but nothin seems to work.
Instead of using customizing webclient. you use default webclient. your problem is replace this.
view.setWebViewClient(new WebViewClient());
add this
view.setWebViewClient(new MyAppWebViewClient());
and also
progressBar.setVisibility(View.INVISIBLE);
not
view.findViewById(R.id.progressBar1).setVisibility(View.GONE);

just changed WebViewClient to MyWebViewClient, progressBar to progressBar1 & ActionBarActivity to AppCompatActivity and every code seems to work :) thank again every1.. :) #Devendra & #akhil :)

After intent of webview url you have to write progressbar.visibility="View.GONE"
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
progressBar.setVisibility(View.GONE);
FGallery.this.progressBar.setProgress(100);
super.onPageFinished(view, url);
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
progressBar.setVisibility(View.VISIBLE);
FGallery.this.progressBar.setProgress(0);
super.onPageStarted(view, url, favicon);
}
}
This is working for me. you can set it as WebViewClient.
After searching on stackoverflow and testing all codes, my Return goBack(); doesn't work.
I do a WebView,
- URL work
- ZOOM work
But I need to reload last page so this is my code I added :
MainActivity.java
package org.sbynight.app;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.os.Bundle;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.webkit.WebChromeClient;
import android.view.KeyEvent;
public class MainActivity extends Activity {
WebView view;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
WebView view = (WebView) this.findViewById(R.id.webView1);
//URL du website - DO NOT CHANGE IT
String url = "http://www.mydomaine.com/";
//loads the WebView completely zoomed out
view.getSettings().setSupportZoom(true);
view.getSettings().setBuiltInZoomControls(true);
//loads WebView Client
view.getSettings().setLoadWithOverviewMode(true);
view.setWebViewClient(new WebViewClient());
view.setWebChromeClient(new WebChromeClient());
view.getSettings().setAppCacheEnabled(false);
//loads URL
view.loadUrl(url);
}
//loads RETURN URL on lastpage
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && this.view.canGoBack()) {
this.view.goBack();
return true;
} else {
new AlertDialog.Builder(this)
.setIcon(android.R.drawable.ic_dialog_alert)
.setTitle("Fermer SByNight")
.setMessage("Etes-vous sur de vouloir quittez SByNight?")
.setPositiveButton("Oui", new DialogInterface.OnClickListener()
{
#Override
public void onClick(DialogInterface dialog, int which) {
finish();
}
})
.setNegativeButton("Non", null)
.show();
}
return true;
}
}
PS: I tested with goPressed(); doesn't work too!
SO you want to go back to the last page if there is one to go back to when the back key is pressed?
use the following:
#Override
public void onBackPressed() {
if(this.view.canGoBack())
{
this.view.goBack();
}
else {
new AlertDialog.Builder(this)
.setIcon(android.R.drawable.ic_dialog_alert)
.setTitle("Fermer SByNight")
.setMessage("Etes-vous sur de vouloir quittez SByNight?")
.setPositiveButton("Oui", new DialogInterface.OnClickListener()
{
#Override
public void onClick(DialogInterface dialog, int which)
{
finish();
}
})
.setNegativeButton("Non", null)
.show();
}
}
}
I haven't really checked the rest of your code. Just the invokable function.
I have a Android Application which is basically uses WebView for all interaction..
How can i access (read) Cookies which are created in WebView (if someone logs in) and than store them somewhere, maybe in SharedPreferences, so that later i can use them.
For example.. on quitting the application .. i can say "Thank Mr.XYZ,do u really want to quit"
Here is my code...
package com.example.hellowebview;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.os.Bundle;
import android.webkit.CookieSyncManager;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class HelloWebView extends Activity {
WebView webview;
private class HelloWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
public void onPageFinished(WebView view, String url) {
CookieSyncManager.getInstance().sync();
}
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
webview = (WebView) findViewById(R.id.webview);
webview.setWebViewClient(new HelloWebViewClient(
));
webview.getSettings().setJavaScriptEnabled(true);
webview.loadUrl("http://www.mysite.com/mobile");
}
public void onBackPressed() {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Thank <<Name Cookie value from Webview >>>,do u really want to quit?")
.setCancelable(false)
.setPositiveButton("Yes",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
finish();
}
})
.setNegativeButton("No", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
AlertDialog alert = builder.create();
alert.show();
}
}
To work with WebView cookies, you can use CookieManager which has some getter and setter methods for you.
