Any help would be appreciated.
Thanks
my CODE is like this :
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
webview = (WebView) findViewById(R.id.webview);
webview.getSettings().setJavaScriptEnabled(true);
webview.loadUrl("http://www.google.com";);
Log.d("sshot","@@@@@ Yahoo @@@@");
//webview.setVisibility(View.VISIBLE);
int mH=webview.getHeight();
Log.d("sshot", "### Height ###"+ mH);
Log.d("sshot","@@@@@ Yahoo1 @@@@");
Picture picture=webview.capturePicture();
Log.d("sshot", "### pic height ###"+ picture.getHeight());
int mHeight=picture.getHeight();
int mWidth=picture.getWidth();
Log.d("sshot", "### mWidth ###"+ mWidth);
// Copy the view canvas to a bitmap
Log.d("sshot","@@@@@ Yahoo2 @@@@");
Canvas tempCanvas = new Canvas();
webview.draw(tempCanvas);
Log.d("sshot","@@@@@ Yahoo3 @@@@");
// if(picture.getWidth()>0)
// {
Bitmap screenshot = Bitmap.createBitmap
(mWidth,mHeight, //////// mHeight and mWidth values are comin
0 ////////
Config.ARGB_8888);
Log.d("sshot","@@@@@ Yahoo4 @@@@");
tempCanvas.drawBitmap(screenshot, 0, 0, null);
// Bitmap bmpBuffer;
// Save to disk
if(screenshot != null) {
ByteArrayOutputStream mByteArrayOpStream = new
ByteArrayOutputStream();
screenshot.compress(Bitmap.CompressFormat.JPEG, 90,
mByteArrayOpStream);
FileOutputStream fos = null;
try {
fos = openFileOutput("yahoo.jpg",
MODE_WORLD_WRITEABLE);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
fos.write(mByteArrayOpStream.toByteArray());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
fos.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
