webView android

webView android - android

I am trying to make a simple WebView in my activity and I keep getting a "webpage not available" page in my android browser on the virtual device as well as an actual device.
I've looked though some samples online as well as the example in my book but I believe something is still missing. Any help would be appreciated. Code is below. wv is referencing a webview object in the main.xml file.
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebSettings;
import android.webkit.WebView;
public class MainActivity extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
WebView wv = (WebView) findViewById(R.id.webView1);
WebSettings webSettings = wv.getSettings();
wv.getSettings().setJavaScriptEnabled(true);
webSettings.setBuiltInZoomControls(true);
wv.loadUrl("http://www.amazon.com");
}
}

For an android webView you need to keep 4 things in mind to make it work perfect.
Give the necessary permission to access internet in your android Manifest.xml
Import necessary libs like webclient and webchromeclient in your YourActivity.java
Enable javascript if you are going to show a webpage which needs java support.
Copy and paste all the image files you use in your webView to all the "drawable" folders in "res" folder of your project.
I've given you the complete code from Manifest to Activity.java. It works perfect. All the best..!
AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

How to get webview (load url) on a specific page of my android app source code?

I want to add webview (load url) in a only page of my app soure code
example : fragment_comingsoon.xml
want it to load an url
anybody can tell me what to do or send me an example code to do that
I will apreciate it so much and thanks in advance guys

**MainActivity**
import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.webkit.WebSettings;
import android.webkit.WebView;
public class MainActivity extends Activity {
private WebView webView = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.webView = (WebView) findViewById(R.id.webview);
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
WebViewClientImpl webViewClient = new WebViewClientImpl(this);
webView.setWebViewClient(webViewClient);
webView.loadUrl("https://www.journaldev.com");
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && this.webView.canGoBack()) {
this.webView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
}
**Setting the WebViewClient:**
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView webView, String url) {
return false;
}
}
**WebViewClientImpl:**
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class WebViewClientImpl extends WebViewClient {
private Activity activity = null;
public WebViewClientImpl(Activity activity) {
this.activity = activity;
}
#Override
public boolean shouldOverrideUrlLoading(WebView webView, String url) {
if(url.indexOf("journaldev.com") > -1 ) return false;
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
activity.startActivity(intent);
return true;
}
}
**Adding Permissions:**
To fetch and load the urls in the WebView we need to add permissions to access the internet from within the app else it won’t be able to load the webpages. The following
line of code needs to be added in the AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="https://schemas.android.com/apk/res/android"
package="com.journaldev.webview" >
<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>

Android webview geo: and tel: links

I'm pretty new to this, and I took this instructions to make the app https://developers.google.com/chrome/mobile/docs/webview/gettingstarted
So, can anybody try to fill what is missing to make it to not crash when geo: or tel: link is pressed and handle the geo: and tel: links like in chrome?
I found the answer!!!
I replaced this code in MyAppWebViewClient.java
public class MyAppWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if(Uri.parse(url).getHost().endsWith("example.com")) {
return false;
}
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
view.getContext().startActivity(intent);
return true;
}
}
with this one
public class MyAppWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getHost() != null && Uri.parse(url).getHost().equals("domain.com"))
{
return false;
}
else {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
view.getContext().startActivity(intent);
return true;
}
}
}

How to load external webpage in WebView

My problem is that the webpage is not loaded inside the WebView.
mWebview.loadUrl("http://www.google.com"); launches the web browser...
This is the code of my activity:
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;
public class Main extends Activity {
private WebView mWebview;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mWebview = new WebView(this);
mWebview.loadUrl("http://www.google.com");
setContentView(mWebview);
}
}
I added the required permission in the Manifest:
<uses-permission android:name="android.permission.INTERNET" />

Thanks to this post, I finally found the solution. Here is the code:
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebResourceError;
import android.webkit.WebResourceRequest;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Toast;
import android.annotation.TargetApi;
public class Main extends Activity {
private WebView mWebview ;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mWebview = new WebView(this);
mWebview.getSettings().setJavaScriptEnabled(true); // enable javascript
final Activity activity = this;
mWebview.setWebViewClient(new WebViewClient() {
#SuppressWarnings("deprecation")
#Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(activity, description, Toast.LENGTH_SHORT).show();
}
#TargetApi(android.os.Build.VERSION_CODES.M)
#Override
public void onReceivedError(WebView view, WebResourceRequest req, WebResourceError rerr) {
// Redirect to deprecated method, so you can use it in all SDK versions
onReceivedError(view, rerr.getErrorCode(), rerr.getDescription().toString(), req.getUrl().toString());
}
});
mWebview .loadUrl("http://www.google.com");
setContentView(mWebview );

try this
webviewlayout.xml:
<?xml version="1.0" encoding="utf-8"?>

android:id="#+id/help_webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scrollbars="none"
/>
In your Activity:
WebView webView;
setContentView(R.layout.webviewlayout);
webView = (WebView)findViewById(R.id.help_webview);
webView.getSettings().setJavaScriptEnabled(true);
webview.loadUrl("http://www.google.com");
Update
Add webView.setWebViewClient(new WebViewController()); to your Activity.
WebViewController class:
public class WebViewController extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}

public class WebViewController extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
webView.setWebViewClient(new WebViewController());

Please use this code:-

openURL();
}
/** Opens the URL in a browser */
private void openURL() {

}
}
Try this code if any query ask me.

It's very simple try integrate these lines of code
first take permission in the Android Manifest file
<uses-permission android:name="android.permission.INTERNET" />
then write some code in you Activity.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.MainActivity">
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/help_webview"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</LinearLayout>
Then write these code in your MainActivity.java
import android.app.Activity;
import android.content.Intent;
import android.content.res.Resources;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.Window;
import android.webkit.WebResourceRequest;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Toast;
public class MainActivity extends Activity{
private WebView mWebview ;
String link = "";// global variable
Resources res;// global variable
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_modernherbal_main);
mWebview = (WebView) findViewById(R.id.help_webview);
WebSettings webSettings = mWebview.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setUseWideViewPort(true);
webSettings.setLoadWithOverviewMode(true);
final Activity activity = this;
mWebview.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(activity, description, Toast.LENGTH_SHORT).show();
}
});
mWebview .loadUrl("http://www.example.com");
}
}
Try this it'll help you to solve your problem

just go into XML file and give id to your webView then in java paste these line:
public class Main extends Activity {
private WebView mWebview;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.Your_layout_file_name);
mWebview = (WebView)findViewById(R.id.id_you_gave _to_your_wenview_in_xml);
mWebview.loadUrl("http://www.google.com");
}
}

I used this code that was cool. but have an error. " neterr_cleartext_not_permitted"
show when you use this code then you will face this problem..
I got a solution of this.you have to add this in your AndroidManifest.xml near about Application
android:usesCleartextTraffic="true"
<uses-permission android:name="android.permission.INTERNET" /> // ignore if you already added. outside of Application.

You can do like this.
webView = (WebView) findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("Your URL goes here");

try this;
webView.loadData("<iframe src='http://www.google.com' style='border: 0; width: 100%; height: 100%'></iframe>", "text/html; charset=utf-8", "UTF-8");

Add Internet permission in AndroidManifest.xml
<uses-permission android:name="android.permission.INTERNET" />
In your Layout:
<?xml version="1.0" encoding="utf-8"?>
<WebView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/webView"
/>
In your Activity
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
try {
progressDialog = new ProgressDialog(this);
url_Api = "https://learn.microsoft.com/en-us/learn";
webView = this.findViewById(R.id.webView);
progressDialog.setMessage(getString(R.string.connection_Wait));
progressDialog.setIndeterminate(false);
progressDialog.setCancelable(true);
progressDialog.show();
LoadUrlWebView( url_Api );
}catch (Exception e){
Log.w(TAG, "onCreate", e);
}
}
private void LoadUrlWebView( String url_api ) {
try {
webView.setWebViewClient(new WebViewClient());
webView.setWebChromeClient(new MyWebChromeClient( url_api ));
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setSupportZoom(true);
webView.getSettings().setAllowContentAccess(true);
webView.getSettings().setBuiltInZoomControls(true);
webView.getSettings().setDisplayZoomControls(false);
webView.loadUrl(url_api);
} catch (Exception e) {
Log.w(TAG, "setUpNavigationView", e);
}
}
private class MyWebChromeClient extends WebChromeClient {
private String urlAccount;
public MyWebChromeClient( String urlAccount ) {
this.urlAccount = urlAccount;
}
#Override
public void onProgressChanged(WebView view, int newProgress) {
try {
//Tools.LogCat(context, "INSIDE MyWebChromeClient | onProgressChanged / newProgress1:" + newProgress);
progressDialog.setMessage(newProgress + "% " + getString(R.string.connection_Wait));
if (newProgress < 100 && !progressDialog.isShowing()) {
if (progressDialog != null)
progressDialog.show();
}
if (newProgress == 100) {
if (progressDialog != null)
progressDialog.dismiss();
}
}catch (Exception e){
Log.w( "onProgressChanged", e);
}
}
#Override
public void onReceivedTitle(WebView view, String title) {
super.onReceivedTitle(view, title);
sharedPreferences = new Shared_Preferences( context );
sharedPreferences.setPageWebView(view.getUrl());
}
}

Add WebView Client
mWebView.setWebViewClient(new WebViewClient());

You need to add WebView client
mWebView.setWebViewClient(new WebViewClient() {
public void onPageFinished(WebView view, String url) {
// do your stuff here
}
});
also you can use onPageFinished to do task after webview done loading web page

activity_main.xml:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
MainActivity.java:
package com.example.myapplication;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class MainActivity extends AppCompatActivity {
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
WebView webView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView = findViewById(R.id.webView);
webView .loadUrl("http://www.google.com");
webView.setWebViewClient(new MyWebViewClient());
}
}
AndroidManifest.xml: (add uses-permission and android:usesCleartextTraffic)
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.myapplication">
<uses-permission android:name="android.permission.INTERNET" />
<application
android:usesCleartextTraffic="true"
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/Theme.MyApplication">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>

Simple Webview activity in kotlin :
class WebViewActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
intent.getStringExtra(URL_EXTRA)?.let { url ->
WebView(this).apply {
settings.javaScriptEnabled = true // check if your need this
settings.domStorageEnabled = true
settings.setSupportZoom(true)
settings.builtInZoomControls = true
settings.displayZoomControls = false
loadUrl(url)
setContentView(this)
}
}
}
companion object {
const val URL_EXTRA = "url"
}
}

Add below method in your activity class.Here browser is nothing but your webview object.
Now you can view web contain page wise easily.
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && browser.canGoBack()) {
browser.goBack();
return true;
}
return false;
}
