Taking Screenshot of Webview in above api 21

I am trying screenshot of webview in above Api 21 and it only capture content from webview that is visible on screen, other part is also getting captured but without any content. Means it shows white space.
I am using below code for taking screenshot.
public static String getScreenShotOf(View view, Context context) {
try {
DisplayMetrics displayMetrics = new DisplayMetrics();
((Activity) context).getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
view.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));
view.measure(displayMetrics.widthPixels, displayMetrics.heightPixels);
view.layout(0, 0, displayMetrics.widthPixels, displayMetrics.heightPixels);
view.buildDrawingCache();
Bitmap bitmap = Bitmap.createBitmap(view.getMeasuredWidth(), view.getMeasuredHeight(), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
view.draw(canvas);
return storeImage(context, bitmap);
}
catch (Exception e) {
UtillsG.showToast("Error while taking screenshot.", context, false);
}
return null;
}
This things works perfectly in LOLLIPOP or below versions.
See screenshot of kitkat and marshmallow devices.
Can anybody help me out for this?
Any support will be appreciated.

You can use root layout as webview and try with below code.
public Bitmap takeScreenshot() {
View rootView = getWindow().getDecorView().findViewById(R.id.PP_Ll);
rootView.setDrawingCacheEnabled(true);
return rootView.getDrawingCache();
}
public void saveBitmap(Bitmap bitmap) {
String root = Environment.getExternalStorageDirectory().toString();
File newDir = new File(root + "/Folder");
newDir.mkdirs();
Random gen = new Random();
int n = 10000;
n = gen.nextInt(n);
String fotoname = "Photo-" + n + ".jpg";
File file = new File(newDir, fotoname);
if (file.exists())
file.delete();
try {
FileOutputStream fos = new FileOutputStream(file);
bitmap.compress(CompressFormat.JPEG, 100, fos);
fos.flush();
fos.close();
Toast.makeText(getApplicationContext(),
"Saved in folder: 'Folder'", Toast.LENGTH_SHORT).show();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}

getWidth must be called from UI thread

getWidth must be called from UI thread..How do i fix it??Im trying to create pdf file..but getWidth,getHeight and getCanvas is coming up errors!!!
private class PdfGenerationTask extends AsyncTask<Void, Void, String> {
#Override
protected String doInBackground(Void... params) {
PdfDocument document = new PdfDocument();
// repaint the user's text into the page
View content = findViewById(R.id.pdf_content);
// crate a page description
int pageNumber = 1;
PageInfo pageInfo = new PageInfo.Builder(content.getWidth(),
content.getHeight() - 20, pageNumber).create();
// create a new page from the PageInfo
Page page = document.startPage(pageInfo);
content.draw(page.getCanvas());
// do final processing of the page
document.finishPage(page);
SimpleDateFormat sdf = new SimpleDateFormat("ddMMyyyyhhmmss");
String pdfName = "pdfdemo"
+ sdf.format(Calendar.getInstance().getTime()) + ".pdf";
File outputFile = new File("/sdcard/PDFDemo_AndroidSRC/", pdfName);
try {
outputFile.createNewFile();
OutputStream out = new FileOutputStream(outputFile);
document.writeTo(out);
document.close();
out.close();
} catch (IOException e) {
e.printStackTrace();
}
return outputFile.getPath();
}

You can get the dimension of your screen like that:
Display display = getWindowManager().getDefaultDisplay();
int screenWidth = display.getWidth();
int screenHeight = display.getHeight();
But it seems to be deprecated. Get it like that now:
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
int screenWidth = metrics.heightPixels;
int screenHeight = metrics.widthPixels;

Implement onPreExecute of AsyncTask and Do the calling of getHeight,getWidth and getCanvas
private class PdfGenerationTask extends AsyncTask<Void, Void, String> {
#Override
protected String onPreExecute(Void params){
this.height=getHeight();
this.width=getWidth();
}
#Override
protected String doInBackground(Void... params) {
PdfDocument document = new PdfDocument();
// repaint the user's text into the page
View content = findViewById(R.id.pdf_content);
// crate a page description
int pageNumber = 1;
PageInfo pageInfo = new PageInfo.Builder(content.getWidth(),
content.getHeight() - 20, pageNumber).create();
// create a new page from the PageInfo
Page page = document.startPage(pageInfo);
content.draw(page.getCanvas());
// do final processing of the page
document.finishPage(page);
SimpleDateFormat sdf = new SimpleDateFormat("ddMMyyyyhhmmss");
String pdfName = "pdfdemo"
+ sdf.format(Calendar.getInstance().getTime()) + ".pdf";
File outputFile = new File("/sdcard/PDFDemo_AndroidSRC/", pdfName);
try {
outputFile.createNewFile();
OutputStream out = new FileOutputStream(outputFile);
document.writeTo(out);
document.close();
out.close();
} catch (IOException e) {
e.printStackTrace();
}
return outputFile.getPath();
}

AsyncTask runs on Different Thread and UI operations happens on Main Thread so you can't get UI related info from different Thread. You have to pass UI related data to your AsyncTask and have work done.
In your Activity's onCreate() method get dimensions like this
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
int screenWidth = metrics.heightPixels;
int screenHeight = metrics.widthPixels;
Canvas canvas = page.getCanvas();
and pass this to your asyncTask as follows
PdfGenerationTask pdfGenerationTask = new PdfGenerationTask(screenWidth, screenHeight, canvas);
pdfGenerationTask.execute();
and update your PdfGenerationTask class as follows
private class PdfGenerationTask extends AsyncTask<Void, Void, String> {
int width, height;
Canvas canvas;
PdfGenerationTask(int width, int height, Canvas canvas) {
this.width = width;
this.height = height;
this.canvas = canvas;
}
#Override
protected String doInBackground(Void... params) {
PdfDocument document = new PdfDocument();
// repaint the user's text into the page
View content = findViewById(R.id.pdf_content);
// crate a page description
int pageNumber = 1;
PageInfo pageInfo = new PageInfo.Builder(width,
height - 20, pageNumber).create();
// create a new page from the PageInfo
Page page = document.startPage(pageInfo);
content.draw(canvas);
// do final processing of the page
document.finishPage(page);
SimpleDateFormat sdf = new SimpleDateFormat("ddMMyyyyhhmmss");
String pdfName = "pdfdemo"
+ sdf.format(Calendar.getInstance().getTime()) + ".pdf";
File outputFile = new File("/sdcard/PDFDemo_AndroidSRC/", pdfName);
try {
outputFile.createNewFile();
OutputStream out = new FileOutputStream(outputFile);
document.writeTo(out);
document.close();
out.close();
} catch (IOException e) {
e.printStackTrace();
}
return outputFile.getPath();
}

how to create and save a screenshot from a surfaceview?

I have an app that I want to be able to capture a screenshot
Here is my code :
public class Screenshot {
private final View view;
/** Create snapshots based on the view and its children. */
public Screenshot(View root) {
this.view = root;
}
/** Create snapshot handler that captures the root of the whole activity. */
public Screenshot(Activity activity) {
final View contentView = activity.findViewById(android.R.id.content);
this.view = contentView.getRootView();
}
/** Take a snapshot of the view. */
public Bitmap snap() {
Bitmap bitmap = Bitmap.createBitmap(this.view.getWidth(), this.view.getHeight(), Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
view.draw(canvas);
return bitmap;
}
}
but the contents of the surfaceView is saved as black.!!!
Please help me, Thanks...

I hope you have used this solution which was posted here Get screenshot of surfaceView in Android
this thing is explained here Take Screenshot of SurfaceView
The SurfaceView's surface is independent of the surface on which View elements are drawn. So capturing the View contents won't include the SurfaceView.........
I hope this Taking screenshot programmatically doesnt capture the contents of surfaceVIew code can help you out more

how to create pdf file with multiple pages from image file in android

How to create PDF file with multiple pages from image file in Android? I created one PDF file from image. That PDF file has one page. That is half of that image. In the right side search part is cut in PDF file.
I am using itext-5.3.4.jar for create PDF.
wbviewnews.loadUrl("http://developer.android.com/about/index.html");
// button for create wbpage to image than image to PDF file
Button btnclick =(Button)findViewById(R.id.btnclick);
btnclick.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Picture p = wbviewnews.capturePicture();
bitmap=null;
PictureDrawable pictureDrawable = new PictureDrawable(p);
bitmap = Bitmap.createBitmap(pictureDrawable.getIntrinsicWidth(),pictureDrawable.getIntrinsicHeight(), Config.ARGB_8888);
//Bitmap bitmap = Bitmap.createBitmap(200,200, Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
canvas.drawPicture(pictureDrawable.getPicture());
ImageView imgdata=(ImageView)findViewById(R.id.imgdata);
imgdata.setImageBitmap(bitmap);
String filename = "pippo.png";
File sd = Environment.getExternalStorageDirectory();
File dest = new File(sd, filename);
String pdffilename = "pippo.pdf";
File pdffilepath = new File(sd, pdffilename);
try {
FileOutputStream out = new FileOutputStream(dest);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
Log.e("Exception", e.toString());
}

document.open();
// URL url = new URL (Environment.getExternalStorageDirectory().getAbsolutePath()+"/"+filename);

Your search through StackOverflow is less I guess cause I found these answer already there having solution, yes its contained in different answer and looking at the Q/A I guess they can solve your problem, if not then keep trying :)
how to Generate Pdf File with Image in android?
How to create a PDF with multiple pages from a Graphics object with Java and itext
iText Example

if your linear layout height is very large than try this code
https://demonuts.com/android-generate-pdf-view/
follow this link and just change the lines
PdfDocument document = new PdfDocument();
PdfDocument.PageInfo pageInfo = new PdfDocument.PageInfo.Builder(convertWidth, 10000, 1).create();
PdfDocument.Page page = document.startPage(pageInfo);
Canvas canvas = page.getCanvas();
Paint paint = new Paint();
paint.setColor(Color.BLUE);
canvas.drawPaint(paint);
Bitmap bitmap = Bitmap.createScaledBitmap(bitmap, convertWidth, 10000, true);
canvas.drawBitmap(bitmap, 0, 0 , null);
document.finishPage(page);`

If you want to create a pdf file with multiple images you can use PdfDocument from Android. Here is a demo:
private void createPDFWithMultipleImage(){
File file = getOutputFile();
if (file != null){
try {
FileOutputStream fileOutputStream = new FileOutputStream(file);
PdfDocument pdfDocument = new PdfDocument();
for (int i = 0; i < images.size(); i++){
Bitmap bitmap = BitmapFactory.decodeFile(images.get(i).getPath());
PdfDocument.PageInfo pageInfo = new PdfDocument.PageInfo.Builder(bitmap.getWidth(), bitmap.getHeight(), (i + 1)).create();
PdfDocument.Page page = pdfDocument.startPage(pageInfo);
Canvas canvas = page.getCanvas();
Paint paint = new Paint();
paint.setColor(Color.BLUE);
canvas.drawPaint(paint);
canvas.drawBitmap(bitmap, 0f, 0f, null);
pdfDocument.finishPage(page);
bitmap.recycle();
}
pdfDocument.writeTo(fileOutputStream);
pdfDocument.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
private File getOutputFile(){
File root = new File(this.getExternalFilesDir(null),"My PDF Folder");
boolean isFolderCreated = true;
if (!root.exists()){
isFolderCreated = root.mkdir();
}
if (isFolderCreated) {
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.US).format(new Date());
String imageFileName = "PDF_" + timeStamp;
return new File(root, imageFileName + ".pdf");
}
else {
Toast.makeText(this, "Folder is not created", Toast.LENGTH_SHORT).show();
return null;
}
}
Here images is the ArrayList of the images with path.

you can set the image like this way...
Bitmap bt=Bitmap.createScaledBitmap(btm, 200, 200, false);
bt.compress(Bitmap.CompressFormat.PNG,100, bos);

How to resize image for list view

i am loading image and title for list view from webservices text is f9 but image is too big.how to resize it and i want to set text in right side and image in left side in each row of list view .i am using this method Bitmap resized = Bitmap.createScaledBitmap(bitmap, 70, 70, true); but nothing appearing on emulator This is my costant class where i am loading image

Instead of
BitmapFactory.Options opt = new BitmapFactory.Options();
bitmap = BitmapFactory.decodeByteArray(data, 0, data.length, opt);
Replace that with
BitmapFactory.Options opts = new BitmapFactory.Options();
opts.inPreferredConfig = Bitmap.Config.ARGB_8888;
bitmap = BitmapFactory.decodeByteArray(data, 0, data.length, opts);

problem was not in my this bitmapfactory class.i hav resolved my isssue.
i just change code in my lazy adapter class.
Bitmap bitmap = Constants.DownloadImage(strUrl);
Bitmap resized=null;
if(bitmap!=null){
resized = Bitmap.createScaledBitmap(bitmap, 100, 100, true);
}else{
System.out.println(strUrl+ "no image here");
}
before i was resizing image in my list view.while it will resize in adpter class of list view.
