Android WebView: A particular site doesn't render properly.

I am working with a WebView which is supposed to open any website.
I have 2 activities-CallingActivity and UrlBrowser. The webview is in UrlBrowser.
The CallingActivity has an EditText which takes the URL from a user and supplies it to the UrlBrowser activity via a bundle object passed as an extra with an Intent object. The UrlBrowser activity uses this URL to load into a webview.
I have to update a progress bar with the loading progress also for which I've used the onProgressChanged method to update values .
The problem I'm facing is that a particular website: www.flipkart.com is not rendering properly. A blank light brownish patch is all that is visible in the webview.
I tried changing the user agent of the WebView. On putting the user agent string of a desktop chrome browser all websites including flipkart opened perfectly, however, their desktop versions opened. I need the mobile version. As soon as I revert to using the user agent of a mobile browser, the same problem occurs. This led me to believe that maybe something is wrong with the user agents so I faked the user agent to chrome's user agent and the problem still persisted.
Here is the code for the two activities and other relevant files:
UrlBrowser.Java
public class UrlBrowser extends AppCompatActivity
{
WebView webView;
ProgressBar progressBar;
String finalUrl;
Context appcontext;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_url_browser);
webView=(WebView)findViewById(R.id.webView);
progressBar=(ProgressBar)findViewById(R.id.progressBar);
progressBar.setMax(100);
Bundle b= getIntent().getExtras();
String finalUrl="http://"+b.getString("url");
appcontext=getApplicationContext();
viewPage(finalUrl);
}
public class MyWebViewClient extends WebViewClient
{
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
Toast.makeText(appcontext,"Waiting for "+url ,Toast.LENGTH_SHORT).show();
view.loadUrl(url);
return true;
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon)
{
progressBar.setVisibility(view.VISIBLE);
}
#Override
public void onPageFinished(WebView view, String url)
{
progressBar.setVisibility(view.INVISIBLE);
}
}
public void viewPage(String url)
{
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setDomStorageEnabled(true);
webView.getSettings().setAppCacheEnabled(true);
webView.ge webView.getSettings().setAppCachePath("/data/data"+getPackageName()+"/cache");
webView.getSettings().setAllowFileAccess(true);
webView.setWebViewClient(new MyWebViewClient());
webView.setWebChromeClient(new WebChromeClient() {
#Override
public void onProgressChanged(WebView view, int newProgress) {
progressBar.setProgress(newProgress);
super.onProgressChanged(view, newProgress);
}
});
webView.loadUrl(url);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_url_browser, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
CallingActivity.java
public class CallingActivity extends AppCompatActivity{
Button goButton;
EditText urlField;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_calling);
goButton=(Button)findViewById(R.id.goButton);
urlField=(EditText)findViewById(R.id.urlField);
}
public void onClick(View v)
{
String url=urlField.getText().toString();
Intent i=new Intent(this,UrlBrowser.class);
Bundle b=new Bundle();
b.putString("url",url);
i.putExtras(b);
startActivity(i);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_calling, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
How can I solve this? Any help appreciated

how to save my text in textview android

I have a code to change the text of textview in a layout according to the value of the edittext (et) in the previous layout
there is MorningDrsGeneral :
public class MorningDrsGeneral extends ActionBarActivity {
Button button ;
EditText et;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.morningdrs);
et = (EditText) findViewById(R.id.et);
addListenerOnButton1();
}
public void addListenerOnButton1() {
final Context context = this;
button = (Button) findViewById(R.id.button1);
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent(context, bookingKamal.class);
intent.putExtra("fn" , et.getText().toString());
startActivity(intent);}
});}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
and there is bookingKamal.java :
public class bookingKamal extends ActionBarActivity {
Button button ;
TextView textView3 ;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.bookingkamal);
textView3 = (TextView) findViewById(R.id.textView3) ;
String A = textView3.getText().toString();
String N = " " ;
if (A.equals(N)){
Intent intent = getIntent();
String texx = intent.getStringExtra("fn") ;
textView3.setText(texx);
}}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
I have to keep the text in the bookingkamal layout .
It means when I go back from this layout and back to it the text should be the same as previous.

Then, it should be like this
bookingKamal.java
String texx;
void onBackPressed() {
Intent intent = new Intent(getApplicationContext(), MorningDrsGeneral.class);
intent.putExtra("texx" , texx);
startActivity(intent);
}
MorningDrsGeneral.java
protected void onCreate(Bundle savedInstanceState) {
et = (EditText) findViewById(R.id.et);
Intent intent2 = getIntent();
if (intent2.getStringExtra("texx") != "") {
String abcd = intent2.getStringExtra("texx");
et.setText(abcd);
}
}

You can use SharedPreferences, this will save everything if you leave the layout or even (if you want) if you close your app. Take a look at the Android documentation at http://developer.android.com/reference/android/content/SharedPreferences.html

Android RadioButton CompoundButton.OnCheckedChangeListener Error

I have a question for my code, it should change the background color of my Start-Activity. I should choose between blue and red with radio buttons (in Radiogroup). I always get this error:
Error:(8, 8) error: com.example.clecks.reaction_game.OnCheckedChangeListener is not abstract and does not override abstract method onCheckedChanged(CompoundButton,boolean) in android.widget.CompoundButton.OnCheckedChangeListener
C:\Users\clecks\Desktop\asdfasdf\app\src\main\java\com\example\clecks\reaction_game\OnCheckedChangeListener.java
When I click on the error message there opens a new class named
OnCheckedChangeListener.java :
public class OnCheckedChangeListener implements CompoundButton.OnCheckedChangeListener {}
Here is my code:
public class activity_settings extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_activity_settings);
colorchange();
}
public void colorchange() {
final RelativeLayout background = (RelativeLayout) findViewById(R.id.start);
final RadioButton changeToBlue = (RadioButton) findViewById(R.id.button_blue);
final RadioButton changeToRed = (RadioButton) findViewById(R.id.button_red);
final Button button_save = (Button) findViewById(R.id.button_save);
button_save.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
changeOption(background);
}
});
changeToBlue.setOnCheckedChangeListener(new RadioButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
changeToBlue(background);
}
});
changeToRed.setOnCheckedChangeListener(new RadioButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
changeToRed(background);
}
});
}
public void changeOption(RelativeLayout background) {
if (background.isEnabled()) {
background.setEnabled(false);
} else {
background.setEnabled(true);
}
}
public void changeToBlue(RelativeLayout background) {
background.setBackgroundColor(0x0000FF00);
background.invalidate();
}
public void changeToRed(RelativeLayout background) {
background.setBackgroundColor(0x0000FF00);
background.invalidate();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_activity_settings, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}}

CompoundButton itself is an abstract class (extending `Button).
You should not have CompoundButton in your activity_activity_settings layout.
Use Button for example instead.

I'm trying to implement this code on Android, im a noob at this [duplicate]

This question already has an answer here:
cannot find symbol method OnClickListener android
(1 answer)
Closed 8 years ago.
I'm trying to make an App for School and I want to make a popup box everytime I press the button.
But then I get the error:
expected class or package
from this line of code:
showPopUp.OnClickListener
on line 25
public class MainActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button showPopUp = (Button) findViewById(R.id.button);
showPopUp.OnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
showSimplePopUp();
}
});
}
private void showSimplePopUp() {
AlertDialog.Builder helpBuilder = new AlertDialog.Builder(this);
helpBuilder.setTitle("Opening Line");
helpBuilder.setMessage("You popped my jingles up");
helpBuilder.setPositiveButton("Ok",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// Do nothing but close the dialog
}
});
// Remember, create doesn't show the dialog
AlertDialog helpDialog = helpBuilder.create();
helpDialog.show();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}

Looks like a typo but it should be:
Button showPopUp = (Button) findViewById(R.id.button);
showPopUp.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
showSimplePopUp();
}
});

You can try this:
private AlertDialog showSimplePopUp() {
AlertDialog.Builder helpBuilder = new AlertDialog.Builder(this);
helpBuilder.setTitle("Opening Line");
helpBuilder.setMessage("You popped my jingles up");
helpBuilder.setPositiveButton("Ok",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// Do nothing but close the dialog
dialog.dismiss();
}
});
// Remember, create doesn't show the dialog
helpBuilder.show();
return helpBuilder.create();
}
Hope it helps!!!

Toast Is not being Displayed in The Android App , But first it was being diplayed then after two days it stopped

I am Very new to Android Programming.. I have listed my code below. MainActivity.java and activity_main.xml. I have tried following solutions but to no avail.
using only this
using getapplicationcontext()
using getbasecontext()
public class MainActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button text2 = (Button) findViewById(R.id.text2);
final WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
text2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(wifiManager.isWifiEnabled()) {
wifiManager.setWifiEnabled(false);
Toast.makeText(getApplicationContext(), "Disabled", Toast.LENGTH_LONG).show();
}
}
}); // Disabling/Enabling Wifi Mechanism
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}

Toast.makeText(MainActivity.this, "Disabled", Toast.LENGTH_LONG).show();
Try using the activity context rather than the application context. See this link for a more thorough description:
When to call activity context OR application context?
