how to surf internet from web view in android - android

Hey guys I want to surf internet from webview in android and i am getting the page for which i have provided url in edittext.But when click on a link inside webview then it is unable to find that page.I have provided internet permission in manifest file and taken web view in layout.
This is my main activity which needs to be corrected somewhere.Thanks in advance and help done will be greatly appreciated.
public class MainActivity extends Activity {
EditText et1;
Button btn;
WebView wv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
et1=(EditText) findViewById(R.id.et1);
btn=(Button) findViewById(R.id.btn);
wv=(WebView) findViewById(R.id.wv);
wv.setWebViewClient(new mybrowser());
btn.setOnClickListener(new OnClickListener() {
#SuppressLint("SetJavaScriptEnabled") #Override
public void onClick(View v)
{
String url = et1.getText().toString();
wv.getSettings().setLoadsImagesAutomatically(true);
wv.getSettings().setJavaScriptEnabled(true);
wv.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
wv.loadUrl("https://"+url);
wv.requestFocus();
}
});
}
class mybrowser extends WebViewClient
{
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
String url1=et1.getText().toString();
view.loadUrl(url1);
return true;
}
}
}

Try to do like
class mybrowser extends WebViewClient
{
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
view.loadUrl(url);
return true;
}
}
and remove String url1=et1.getText().toString();

Webpage not being displayed in webview & getting redirected to browser

I am trying to implement basic webview. However, when I enter the url and click on a button to load it, I get a popup asking me to choose from a list of applications to load that webpage.The webpage then loads perfectly in the browser.I have added the INTERNET permission in the Manifest file. Please help me to spot the error or missing logic.
public class MainActivity extends Activity {
private static final String TAG = "WebViewActivity";
Button button1;
EditText et1;
String address;
WebView wv1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button1=(Button)findViewById(R.id.button1);
et1=(EditText)findViewById(R.id.editText1);
wv1=(WebView)findViewById(R.id.webView1);
wv1.getSettings().setJavaScriptEnabled(true);
button1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
address=et1.getText().toString();
Log.d(TAG,"url has been stored in address");
wv1.loadUrl(address);
Log.d(TAG,"url should now be loaded in webview");
}
});
}
Please set setWebViewClient listener:
webview.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url){
// do your handling codes here, which url is the requested url
view.loadUrl(url);
return false;
}
});
now replace this code with your code...
public class MainActivity extends Activity {
private static final String TAG = "WebViewActivity";
Button button1;
EditText et1;
String address;
WebView wv1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button1=(Button)findViewById(R.id.button1);
et1=(EditText)findViewById(R.id.editText1);
wv1=(WebView)findViewById(R.id.webView1);
wv1.setWebViewClient(new MyBrowser());
wv1.getSettings().setJavaScriptEnabled(true);
button1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
address=et1.getText().toString();
Log.d(TAG,"url has been stored in address");
wv1.loadUrl(address);
Log.d(TAG,"url should now be loaded in webview");
}
});
}
private class MyBrowser extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
}
}

facebook like on webview android shows blank screen after login

I utilize the facebook html like for my app to open a webview like this https://developers.facebook.com/docs/plugins/like-button/
The webview shows a Like and Share button, but after I login to facebook, it doesnt return to the Like and Share button, but a blank page, the share button works fine.
So how do I return to the facebook like url after logging in?
public class LikeFacebookActivity extends BaseActivity {
private WebView webView;
private final String URL = "facebookIDhere";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.like_facebook_webview);
webView = (WebView) findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setAppCacheEnabled(true);
webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
showLoading();
webView.setWebViewClient(new MyWebViewClient());
webView.loadUrl(URL);
ActionBar actionbar = getActionBar();
actionbar.setCustomView(R.layout.actionbar_top_like_facebook);
actionbar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
Button backButton = (Button) findViewById(R.id.buttonGeneralBack);
backButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
onBackPressed();
}
});
}
#Override
public void onBackPressed() {
finish();
overridePendingTransition(R.anim.animation_slide_from_left,
R.anim.animation_slide_to_right);
}
public class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if(url.contains("something")) return true;
return false;
}
public void onPageFinished(WebView view, String url) {
hideLoading();
}
}
}
I have solved this, just use system.out.println to see which page does facebook load after loggin in
public class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if(url.contains("something")) return true;
return false; //Default is to not override unless our condition is met.
}
public void onPageFinished(WebView view, String url) {
hideLoading();
//String webUrl = webView.getUrl();
//System.out.println(webUrl);
if(url.startsWith("https://www.facebook.com/plugins/close_popup.php#_=_")){
String redirectUrl = URL;
view.loadUrl(redirectUrl);
return;
}
super.onPageFinished(view, url);
}
}

Android Webview shows error in emulator

i have a problem with loading a webview from a string url.
here is the code of an activity with only WebView.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_web);
Intent intent=getIntent();
String url=intent.getStringExtra("url");
//EditText edit=(EditText)findViewById(R.id.editText1);
//String url=edit.getText().toString();
WebView webview=(WebView)findViewById(R.id.webView1);
webview.loadUrl(url);
webview.setWebViewClient(new WebViewClient());
}`
and code of the calling activity
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void onGo(View v)
{
EditText edit=(EditText)findViewById(R.id.editText1);
Intent intent=new Intent(MainActivity.this,WebActivity.class);
intent.putExtra("url", edit.getText().toString());
startActivity(intent);
}
i have even added the android.permissions.INTERNET in the manifest
but still i cannot view the page with the click of the button in MainActivity.
From the comment
yes the real device has the same error with "www.google.com"
Use
http://www.google.com
Also make sure you have internet permission mentioned in manifest file
private class HelloWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
