Answer 2

Try this code for webview. It works on all versions of android. Copy and paste all the image files you use into all the "drawable" folders inside "res" folder of you project. All the best..

 MainActivity.java: package com.example.yourappname; import android.app.Activity; import android.app.AlertDialog; import android.content.DialogInterface; import android.content.Intent; import android.content.res.Configuration; import android.graphics.Bitmap; import android.net.Uri; import android.os.Bundle; import android.view.KeyEvent; import android.view.View; import android.webkit.ValueCallback; import android.webkit.WebView; import android.webkit.WebViewClient; import android.webkit.WebChromeClient; import android.widget.Button; import android.widget.EditText; public class MainActivity extends Activity { WebView web; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); web = (WebView) findViewById(R.id.webView1); web = new WebView(this); web.getSettings().setJavaScriptEnabled(true); //change the url below to the url you need web.loadUrl("http://www.xyxyxyxyxyxy.com"); web.setWebViewClient(new myWebClient()); web.setWebChromeClient(new WebChromeClient()); setContentView(web); } public class myWebClient extends WebViewClient { @Override public void onPageStarted(WebView view, String url, Bitmap favicon) { // TODO Auto-generated method stub super.onPageStarted(view, url, favicon); } @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { // TODO Auto-generated method stub view.loadUrl(url); return true; } @Override public void onPageFinished(WebView view, String url) { // TODO Auto-generated method stub super.onPageFinished(view, url); } } //flip screen not loading again @Override public void onConfigurationChanged(Configuration newConfig){ super.onConfigurationChanged(newConfig); } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { if(event.getAction() == KeyEvent.ACTION_DOWN){ switch(keyCode) { case KeyEvent.KEYCODE_BACK: if(web.canGoBack()){ web.goBack(); } else { backButtonHandler(); } return true; } } return super.onKeyDown(keyCode, event); } public void backButtonHandler() { AlertDialog.Builder alertDialog = new AlertDialog.Builder( MainActivity.this); // Setting Dialog Title // Setting Dialog Message // You can delete the next 2 lines if you wish alertDialog.setTitle(""); alertDialog.setIcon(R.drawable.dialog_icon); alertDialog.setMessage("Exit Now?"); // Setting Icon to Dialog // Setting Positive "Yes" Button alertDialog.setPositiveButton("Exit", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { finish(); } }); // Setting Negative "NO" Button alertDialog.setNegativeButton("No", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { // Write your code here to invoke NO event dialog.cancel(); } }); // Showing Alert Message alertDialog.show(); } }
