open all website URL within App and external URLs using external browser in WebView?

I have this code, but not because it works, it keeps opening in webview and what I want is that the links do not belong to my website open in your default browser. Any idea? thanks
here is my MainActivity.java
package club.moviestreet.www.webviewapp;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class MainActivity extends AppCompatActivity {
private WebView mywebView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mywebView = (WebView) findViewById(R.id.webview);
WebSettings webSettings= mywebView.getSettings();
webSettings.setJavaScriptEnabled(true);
mywebView.loadUrl("http://moviestreet.club/");
// Line of Code for opening links in app
mywebView.setWebViewClient(new WebViewClient());
}
//Code For Back Button
#Override
public void onBackPressed() {
if(mywebView.canGoBack())
{
mywebView.goBack();
}
else
{
super.onBackPressed();
}
}
}

What you need is shouldOverrideUrlLoading of WebViewClient
Give the host application a chance to take over the control when a new url is about to be loaded in the current WebView. If WebViewClient is not provided, by default WebView will ask Activity Manager to choose the proper handler for the url. If WebViewClient is provided, return true means the host application handles the url, while return false means the current WebView handles the url.
Replace
mywebView.setWebViewClient(new WebViewClient());
With this:
mywebView.setWebViewClient(new WebViewClient() {
#SuppressWarnings("deprecation")
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (!url.startsWith("http://moviestreet.club/")) {
Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(i);
return true;
}
return false;
}
});

My application keeps on crashing using Webview?

I'm just testing my application at the moment. However, it keeps on crashing on the loading screen. Once it loads it redirects to the login or users account if they have already logged in.
However, I keep getting these error messages in android studios console log when built the application.
W/cr_CrashFileManager: /data/user/0/chrisbeckett.********/cache/WebView/Crash Reports does not exist or is not a directory
// I've put the stars as I can't show the name of the application yet.
W/cr_AwContentsClient: Denied starting an intent without a user gesture, URI http://********.********.com/login
My current code:
package chrisbeckett.**********;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Window;
import android.webkit.WebChromeClient;
import android.webkit.WebSettings;
import android.webkit.WebView;
public class MainActivity extends AppCompatActivity {
private WebView mWebView;// Instance of WebChromeClient for handling all chrome functions.
private volatile WebChromeClient mWebChromeClient;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mWebView = (WebView) findViewById(R.id.activity_main_webview);
// Enable Javascript
WebSettings webSettings = mWebView.getSettings();
webSettings.setDomStorageEnabled(true);
webSettings.setJavaScriptEnabled(true);
webSettings.setCacheMode(WebSettings.LOAD_DEFAULT);
webSettings.setAppCacheEnabled(true);
webSettings.setAppCacheMaxSize(100 * 1000 * 1000);
mWebView.setWebChromeClient(new WebChromeClient());
mWebView.loadUrl("http://********.*********.com/loading");
}
/**
* Set the WebChromeClient.
* #param client An implementation of WebChromeClient.
*/
public void setWebChromeClient(WebChromeClient client) {
mWebChromeClient = client;
}
}
Further information:
My code works on all web browsers on a desktop when viewing it in a mobile mode in the inspector when testing before putting it in App format.
If you require any more information please let me know.

try below code this may work
mWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return false;
}
});

You can use it for Android N
mWebView.setWebViewClient(new WebViewClient() {
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
}
#SuppressWarnings("deprecation")
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return false;
}
#TargetApi(Build.VERSION_CODES.N)
#Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
view.loadUrl(request.getUrl().toString());
return true;
}
});

android:usesCleartextTraffic="true" in application tag
add above line in your manifest.xml file.

You need to add the Internet Permission
<uses-permission android:name="android.permission.INTERNET"/>

Android webview page unavailable

I developed a small android webview app to access an internal (local network) PHP based site.
Here is my code:
package com.CheckInventory;
import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.WindowManager;
import android.webkit.WebChromeClient;
import android.webkit.WebSettings;
import android.webkit.WebStorage;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Toast;
#SuppressWarnings("unused")
public class CheckInventoryActivity extends Activity {
WebView webview;
String username;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
setContentView(R.layout.main);
webview = (WebView) findViewById(R.id.webview);
WebView webView = (WebView) findViewById(R.id.webview);
webView.setBackgroundColor(0);
webView.setBackgroundResource(R.drawable.myimage);
webView.addJavascriptInterface(new JavaScriptInterface(this), "Android");
WebSettings webSettings = webview.getSettings();
webSettings.setLoadWithOverviewMode(true);
webview.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
webSettings.setJavaScriptEnabled(true);
webSettings.setJavaScriptCanOpenWindowsAutomatically(true);
webSettings.setDatabasePath("/data/data/"+this.getPackageName()+"/databases/");
webSettings.setDomStorageEnabled(true);
webview.setWebChromeClient(new WebChromeClient());
webview.loadUrl("http://192.168.0.124/android");
webview.setWebViewClient(new HelloWebViewClient());
}
private class HelloWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
#Override
public boolean onKeyDown (int keyCode, KeyEvent event) {
if((keyCode == KeyEvent.KEYCODE_BACK) && webview.canGoBack()){
//webview.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
}
The site has authentication, but I would like to add some authentication between the app and the site (How do I do this? pass a parameter maybe when the url is invoked), secondly and more importantly, where specifically do I put the onReceivedError so the user never sees the url or the page down if they walk away from the building or loose connection.
public void onReceivedError(WebView view, int errorCod,String description, String failingUrl) {
Toast.makeText(Webform.this, "Your Internet Connection May not be active Or " + description , Toast.LENGTH_LONG).show();
}
I saw this explanation in Detecting Webview Error and Show Message but I do not know where to implement it.
Thank you in advance

You need to create class which extends WebViewClient and implements method OnReceivedError
like this
class myWebClient extends WebViewClient {
#Override
public void onReceivedError(WebView view, int errorCode,
String description, String failingUrl) {
Toast.makeText(Webform.this, "Your Internet Connection May not be active Or " + description , Toast.LENGTH_LONG).show();
super.onReceivedError(view, errorCode, description, failingUrl);
}
}
and then you need to set new WebViewClient to your WebView
web = (WebView) findViewById(R.id.webview);
web.setWebViewClient(new myWebClient());
Hope this helps

You can add onReceivedError in Your HelloWebViewClient class and handle what you want to handle when you get error.
private class HelloWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error){
//Your code to do
Toast.makeText(getActivity(), "Your Internet Connection May not be active Or " + error , Toast.LENGTH_LONG).show();
}
}

Android authentication via webview

I'm sorry for this as I am very Green at this Android Development, and I maybe beating a dead horse here-
A software tjat we use has a mobile version, but it's a mobile website, I am trying to build this into a standalone web-app using webview.
The app will get me to the login screen, but when I attempt to login the the pop-up showing its logging in, and in my webview, it is sticking there. It doesn't move past this point.
In the default browser it works fine.
Can you please assist me in what I need to do to get pass this in the most simple terms? ;-) Thank you!
package com.giantflyingsaucer;
import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class WebPageLoader extends Activity
{
final Activity activity = this;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
setContentView(R.layout.main);
WebView webView = (WebView) findViewById(R.id.webview);
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress)
{
activity.setTitle("Loading...");
activity.setProgress(progress * 100);
if(progress == 100)
activity.setTitle(R.string.app_name);
}
});
webView.setWebViewClient(new WebViewClient() {
#Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl)
{
// Handle the error
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
view.loadUrl(url);
return true;
}
});
webView.loadUrl("http://URL.USED.FOR/WEBAPP");
}
}

This was resolved by using
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
}

perhaps your login is trying to make use of some web plugin. Try adding one or both of these:
mWebView.getSettings().setPluginState(WebSettings.PluginState.ON);
mWebView.getSettings().setPluginsEnabled(true);
