Do you have more Activities? Try this:
Button buttonBack;
buttonBack = (Button) findViewById(R.id.buttonBack);
//in your layout set android:id="#+id/buttonBack" (this is just an example)
buttonBack.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(SecondActivity.this, MainActivity.class);
startActivity(intent);
}
});

With Stack implementation: If you want to go previous webpage by pressing back button you have to do two things.
Override onBackPressed
Saved your previous web page address on Stack.
Declare a String type stack
private Stack<String> stack = new Stack<>();
When new url is loading put the current url into stack. Like
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
stack.add(url);
}
}
Now, override onBackPressed
#Override
public void onBackPressed() {
if (stack.size() > 1 && stack != null) {
stack.pop();
load(stack.peek());
} else {
super.onBackPressed();
}
}
}
Here, load() is a methoad for loading webpage.
private void load(String urlToLoad) {
pd = new ProgressDialog(YourActivity.this);
pd.setMessage("Please wait Loading...");
pd.show();
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setPluginState(WebSettings.PluginState.ON);
webView.setLayerType(View.LAYER_TYPE_HARDWARE, null);
webView.loadUrl(urlToLoad);
webView.setWebViewClient(new MyWebViewClient());
}
With WebView Native API: (As you describe)
#Override
public void onBackPressed() {
if(mainWebView.canGoBack())
mainWebView.goBack();
else
onShowQuitDialog();
}
No need to Override onKeyDown

Unable to Full Screen Youtube Video Inside Custom Webview

mCustomView.setVisibility(View.GONE);
// Remove the custom view from its container.
customViewContainer.removeView(mCustomView);
customViewCallback.onCustomViewHidden();
mCustomView = null;
}
}

To achieve this you should:
Implement showCustomView and hideCustomView methods of WebChromeClient.
Set android:hardwareAccelerated="true" to your MainActivity in AndroidManifest.xml.
There are two classes that inherit the WebChromeClient in your code (myWebChromeClient and MyWebChromeClient). The first implements showCustomView and hideCustomView methods and it seems fully working with full-screen video. The second one don't. But you (accidentally?) set the second as WebChromeClient to your WebView.
To fix this just change the line
webView.setWebChromeClient(new MyWebChromeClient());
to
mWebChromeClient = new myWebChromeClient();
webView.setWebChromeClient(mWebChromeClient);
in your initWebView() method.
UPD:
To lock orientation on portrait in normal (not full-screen) mode add following line into onHideCustomView() method:
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
To let the system decide the best orientation in full-screen mode add this line to onShowCustomView(View view, CustomViewCallback callback) method:
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED);

Working Perfectly.

Solution Original Source

Referring to the code Sheharyar Ejaz has posted, I replaced 2 lines to improve the result.
THe first line I replaced is in onShowCustomView, so when user click Youtube fullscreen option of a video, the video will automatically expand into lansdcape fullscreen like native Youtube.
To achieve that, I replaced this line :
this.mOriginalOrientation = getRequestedOrientation();
with this line :
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
The second line I replaced is in onHideCustomView, so when user minimize the fullscreen video, it will revert into the phone's present layout.
What I do is I replaced this line :
this.mOriginalOrientation = getRequestedOrientation();
with this line :
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED);
But, quite different with the suggestion by erakitin, I did not set android:hardwareAccelerated="true" to my MainActivity/WebView Activity in AndroidManifest.xml.

Android metaio AREL launch url in app and NOT external browser

This is based on the Metaio sdk, but not sure the problem is dependant of it. I have created a basic AREL based Android app, using the Creator. On detection of marker I would like to load a url in a webview.
However when the marker is detected, I get the dialog of choosing what browser to open the url in.
How can I override that and make it open inside a webview in my app?
I tried using public boolean shouldOverrideUrlLoading(WebView view, String url) but it does not get called.
How can I make sure I get all the urls that are attempted to open by an Activity? so I can direct the calls to a webview..
In my activity I have this inside onCreate:
mWebView = (WebView) findViewById(R.id.webview);
mWebView.setWebViewClient(new WebViewHandler());
and this outside onCreate:
class WebViewHandler extends WebViewClient
{
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon)
{
Log.d("LEE","ping1!!!!!"+url);
mProgress.setVisibility(View.VISIBLE);
}
#Override
public void onPageFinished(WebView view, String url)
{
Log.d("LEE","ping2!!!!!"+url);
mProgress.setVisibility(View.GONE);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
Log.d("LEE","Triggered url: !!!!!"+url);
}
}

You have a mistake in your override. You should be returning false at the end of shouldOverrideUrlLoading(). This will allow your WebView to handle the request instead of the system.

Have you tried to do it directly in AREL using arel.Media.openWebsite(url, false);
http://dev.junaio.com/arel/documentationArelJS/symbols/arel.Media.html#.openWebsite
You can edit arel code from creator directly

I solved it by overriding openWebsite() inside ARELInterpreterCallback like this...
//ARELViewActivity.java
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import com.metaio.cloud.plugin.view.WebViewActivity;
import com.metaio.sdk.ARELActivity;
import com.metaio.sdk.jni.IARELInterpreterCallback;
public class ARELViewActivity extends ARELActivity {
protected ARELInterpreterCallback myARELCallback;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
myARELCallback = new ARELInterpreterCallback();
if (mARELInterpreter != null)
mARELInterpreter.registerCallback(myARELCallback);
}
#Override
protected int getGUILayout() {
return 0;
}
class ARELInterpreterCallback extends IARELInterpreterCallback
{
#Override
public void onSDKReady()
{
loadARELScene();
}
#Override
public boolean openWebsite(String url, boolean openInExternalApp){
//url is set with arel.Media.openWebsite("template://item#", false); inside logic.js
if (url.contains("template://")) {
if (url.contains("item1")) {
urlSub = url.substring(14, url.length());
runOnUiThread(new Runnable() {
#Override
public void run() {
Intent i = new Intent(ARELViewActivity.this, WebViewActivity.class);
i.putExtra(getPackageName() + ".URL", "http://www.google.com.mx");
startActivity(i);
}
});
return true;
} else {
urlSub = url.substring(14, url.length());
runOnUiThread(new Runnable() {
#Override
public void run() {
Intent i = new Intent(ARELViewActivity.this, WebViewActivity.class);
i.putExtra(getPackageName() + ".URL", "http://www.yahoo.com.mx");
startActivity(i);
}
});
return true;
}
} else {
return false;
//return super.openWebsite(url, openInExternalApp);
}
}
}
}

webview shows everytime the content from the last loadurl() method

i have the Problem that i load a website with the loadDataWithBaseURL method. There i load a prepared internetsite in a webview. if i go back in my previous activity and start the webview activity it loads the same prepared website with loadDataWithBaseURL() method but i get a webview with twice the content. For example Hello World and the second Hello World.
My Code is the followed:
package de.http.test;
import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.webkit.WebBackForwardList;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class WebviewActivity extends Activity {
WebView webview;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.mywebview);
Bundle bundle= this.getIntent().getExtras();
String param1 = bundle.getString("Weburl");
getDetailWebsite(param1);
webview = (WebView) findViewById(R.id.webview);
webview.setWebViewClient(new HelloWebViewClient());
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setBuiltInZoomControls(true);
loadWebview();
}
public void loadWebview()
{
webview.clearView();
webview.loadDataWithBaseURL("http://branchenportal-schlitz.de", HttpHelperClass.htmlDetailWebsiteCode, "text/html", "UTF-8", HttpHelperClass.htmlDetailWebsiteCode);
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && webview.canGoBack()) {
webview.goBack();
WebBackForwardList mWebBackForwardList = webview.copyBackForwardList();
String historyUrl = mWebBackForwardList.getItemAtIndex(mWebBackForwardList.getCurrentIndex()).getUrl();
if(historyUrl.contains("<html>"))
{
loadWebview();
}
return true;
}
return super.onKeyDown(keyCode, event);
}
private void getDetailWebsite(String url)
{
try{
HttpHelperClass.executeHttpGetDetailWebsite(url,this);
}catch (Exception ex)
{
ex.printStackTrace();
}
}
private class HelloWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
if(url.contains("branchenportal-schlitz.de"))
{
view.clearHistory();
}
super.onPageFinished(view, url);
}
}
#Override
protected void onStop() {
webview.clearCache(true);
webview.clearView();
webview.clearHistory();
webview.destroy();
super.onStop();
}
}
Is there anybody who knows what iam doing wrong?
Thanks in advance.
With regards

OK well to trouble shoot this I would start by getting rid of (commenting out) all of your code below public boolean onKeyDown(int keyCode, KeyEvent event). Then you can see if its in your onCreate or not. But that's up to.
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.buttons);
wb = new WebView(this);
wb.getSettings().setJavaScriptEnabled(true);
wb.setWebViewClient(new HelloWebViewClient());
final String urlToLoad = "http://www.yourWebsite.com";
wb.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT);
wb.loadUrl(urlToLoad);
}
start here then start adding your extra code back in.

android webview client activity indicator

I got the code for showing activity indicator in a webview. I checked more than one reference and still I couldn't get it working. Can you please help me to debug my code below?
The activity indicator is not coming with below code
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
final BaseActivity MyActivity = ReviewWebActivity.this;
setContentView(R.layout.review_web);
getWindow().setFeatureInt(Window.FEATURE_PROGRESS,
Window.PROGRESS_VISIBILITY_ON);
ScannedProduct product = getReviewUrl();
reviewUrl = product.getReviewLink();
if (reviewUrl == null) {
String err = product.getErrorCode();
if(err.equals("")) err ="No Data Available for this product";
Toast.makeText(getApplicationContext(),
"No Data Available for this product", 1).show();
return;
}
webReview = (WebView) findViewById(R.id.webReview);
webReview.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
// Make the bar disappear after URL is loaded, and changes
// string to Loading...
MyActivity.setTitle("Loading...");
MyActivity.setProgress(progress * 1000); // tried with 100 also
}
});
webReview.setWebViewClient(new ReviewWebClient());
webReview.getSettings().setJavaScriptEnabled(true);
webReview.loadUrl(reviewUrl);
}

import android.app.Activity;
import android.app.ProgressDialog;
import android.os.Bundle;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class SandbarinFacebook extends Activity {
WebView mWebView;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final ProgressDialog pd = ProgressDialog.show(this, "", "Loading...",true);
mWebView = (WebView) findViewById(R.id.webkitWebView1);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setSupportZoom(true);
mWebView.getSettings().setBuiltInZoomControls(true);
mWebView.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url) {
if(pd!=null && pd.isShowing())
{
pd.dismiss();
}
}
});
mWebView.loadUrl("http://www.yahoo.co.in");
setTitle("Yahoo!");
}
}

Write below code in Activity's onCreate method.
webView.setWebChromeClient(new ChromeClient());
progress=ProgressDialog.show(this, "", "Loading...");
webView.loadUrl(url);
Create ChromeClient class in same activity.
private class ChromeClient extends WebChromeClient {
#Override
public void onProgressChanged(WebView view, int newProgress) {
if(newProgress >= 85) {
progress.dismiss();
}
super.onProgressChanged(view, newProgress);
}
}
Declare objects accordingly. Get back to me If you still face error. I will provide full source code.

I cannot post a comment because I don't have enough reputation points, but just a quick comment on the accepted answer: Check for null before checking if the dialog is showing. This will avoid the dreaded NPE.
if(pd != null && pd.isShowing()) { ... }

Kotlin snipet:
myProgressBar.show()
myWebView.webViewClient = object : WebViewClient() {
override fun onPageFinished(view: WebView, url: String) {
myProgressBar.hide()
