Take multiple images from the gallery and make a pdf

I am trying to get multiple images from the gallery and make them a PDF here is the code. In the code, I can take multiple images from the user and also make them PDF. But the PDF contains only one image even though I selected multiple images it only shows one image in pdf. I have attached the code below.
if (requestCode == REQUEST_CODE && resultCode == RESULT_OK && data != null) {
bitmaps = new ArrayList < > ();
ClipData clipData = data.getClipData();
if (clipData != null) {
for (int i = 0; i < clipData.getItemCount(); i++) {
try {
Uri uri = clipData.getItemAt(i).getUri();
InputStream inputStream = getContentResolver().openInputStream(uri);
Bitmap bitmap = BitmapFactory.decodeStream(inputStream);
bitmaps.add(bitmap);
pdfDocument = new PdfDocument();
PdfDocument.PageInfo pageInfo = new PdfDocument.PageInfo.Builder(bitmap.getWidth(), bitmap.getHeight(), bitmaps.size())
.create();
for (int k = 0; k <= i; k++) {
PdfDocument.Page page = pdfDocument.startPage(pageInfo);
Canvas canvas = page.getCanvas();
Paint paint = new Paint();
paint.setColor(Color.parseColor("#FFFFFF"));
canvas.drawPaint(paint);
bitmap = Bitmap.createScaledBitmap(bitmap, bitmap.getWidth(), bitmap.getHeight(), true);
paint.setColor(Color.BLUE);
canvas.drawPaint(paint);
canvas.drawBitmap(bitmap, 0, 0, null);
pdfDocument.finishPage(page);
}
bitmap.recycle();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IndexOutOfBoundsException ex) {
ex.printStackTrace();
}
}
File root = new File(Environment.getExternalStorageDirectory(), "PDF Folder");
if (!root.exists()) {
root.mkdir();
}
File file = new File(root, "image" + ".pdf");
try {
FileOutputStream fileOutputStream = new FileOutputStream(file);
pdfDocument.writeTo(fileOutputStream);
pdfDocument.close();
} catch (IOException io) {
io.printStackTrace();
} catch (NullPointerException n) {

How to split Html String Based on Html tag

I have String with Html format. My Html can contains any tags like image , video , ...
I can now handle image and text like this correctly :
I have a textView in my xml:
TextView textView = new TextView(DetailActivity.this);
textView.setText(Html.fromHtml(content, new Html.ImageGetter() {
#Override
public Drawable getDrawable(String source) {
try {
URI uri = new URI(source);
URL videoUrl = uri.toURL();
File tempFile = new File(videoUrl.getFile());
filename = tempFile.getName();
} catch (Exception e) {
}
Drawable drawable = null;
ContextWrapper cw1 = new ContextWrapper(DetailActivity.this);
File directory1 = cw1.getDir("multiImage", Context.MODE_PRIVATE);
final File myImageFile1 = new File(directory1, filename);
File f = new File(myImageFile1.getAbsolutePath());
Log.i("multiImage", filename);
final ImageView imageView = new ImageView(DetailActivity.this);
if (f.exists()) {
drawable = Drawable.createFromPath(myImageFile1.getAbsolutePath());
//drawable.setBounds(0, 0, drawable.getIntrinsicHeight(), drawable.getIntrinsicWidth());
int imgH = drawable.getIntrinsicHeight();
int imgW = drawable.getIntrinsicWidth();
int padding = 20;
int realWidth = ScreenW - (2 * padding);
int realHeight = imgH * realWidth / imgW;
drawable.setBounds(padding, 0, realWidth, realHeight);
} else {
Picasso.with(DetailActivity.this)
.load(source)
.into(imageView, new Callback() {
#Override
public void onSuccess() {
BitmapDrawable draw = (BitmapDrawable) imageView.getDrawable();
Bitmap bitmap = draw.getBitmap();
FileOutputStream outStream = null;
File outFile = new File(myImageFile1.getAbsolutePath());
try {
outStream = new FileOutputStream(outFile);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outStream);
try {
outStream.flush();
} catch (IOException e) {
e.printStackTrace();
}
try {
outStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
#Override
public void onError() {
}
});
URL sourceURL;
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
try {
sourceURL = new URL(source);
URLConnection urlConnection = sourceURL.openConnection();
urlConnection.connect();
InputStream inputStream = urlConnection.getInputStream();
BufferedInputStream bufferedInputStream =
new BufferedInputStream(inputStream);
Bitmap bm = BitmapFactory.decodeStream(bufferedInputStream);
// convert Bitmap to Drawable
drawable = new BitmapDrawable(getResources(), bm);
int imgH = drawable.getIntrinsicHeight();
int imgW = drawable.getIntrinsicWidth();
int padding = 20;
int realWidth = ScreenW - (2 * padding);
int realHeight = imgH * realWidth / imgW;
drawable.setBounds(padding, 0, realWidth, realHeight);
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
return drawable;
}
}, new UlTagHandler()));
But I can not show video using above code.
I want to split my string --> from the first until the video tag and then video tag at the end of video tag and the rest of string .

Android: Images are stored at the end of the gallery

can somebody help me with this problem?
I want that images are displayed at the beginning of the gallery.
What have i to change in my code?
OutputStream fOut = null;
try {
String path = getFilesDir().getPath();
File file = new File(path, "LT-IMG-"+ts+".jpg");
fOut = new FileOutputStream(file);
Bitmap bitmap = ((BitmapDrawable)photoView.getDrawable()).getBitmap();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fOut);
fOut.flush();
fOut.close();
MediaStore.Images.Media.insertImage(getContentResolver(), file.getAbsolutePath(), file.getName(), file.getName());
} catch (IOException ex) {
ex.printStackTrace();
}

MediaStore.Images.Media.insertImage(getContentResolver(), yourBitmap, yourTitle , yourDescription);
The former code will add the image at the end of the gallery. If you want to modify the date so it appears at the beginning or any other metadata, see the code below (Cortesy of S-K, samkirton):

Android render pdf to bitmap with itext library

I am trying to convert a pdf stored in my assets folder into bitmap using PdfViewer.jar.
This is my code:
public static Bitmap renderToBitmap(InputStream inStream) {
Bitmap bitmap = null;
try {
byte[] bArray = IOUtils.toByteArray(inStream);
ByteBuffer buf = ByteBuffer.wrap(bArray);
PDFPage mPdfPage = new PDFFile(buf).getPage(0, true);
float width = mPdfPage.getWidth();
float height = mPdfPage.getHeight();
bitmap = mPdfPage.getImage((int) (width), (int) (height), null);
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
inStream.close();
} catch (IOException e) {
// do nothing because the stream has already been closed
}
}
return bitmap;
}
This code is doing what I need. But the resulting bitmap quality is very poor.
How can I increase the quality of bitmap created ?

Android Google Maps V2 - Sd card as Tile Provider

I'm developing an android app using Google Maps API V2 and i have to use offline tiles, i have all tiles (from open street maps in png format) of my entire city in my SD Card.
I already tried to use TileProvider Interface but didn't work.
How can i do that ?
Thanks in advance.

I modified somethings and it worked. Here is the code:
CustomMapTileProvider.java
public class CustomMapTileProvider implements TileProvider {
private static final int TILE_WIDTH = 256;
private static final int TILE_HEIGHT = 256;
private static final int BUFFER_SIZE = 16 * 1024;
Override
public Tile getTile(int x, int y, int zoom) {
byte[] image = readTileImage(x, y, zoom);
return image == null ? null : new Tile(TILE_WIDTH, TILE_HEIGHT, image);
}
private byte[] readTileImage(int x, int y, int zoom) {
FileInputStream in = null;
ByteArrayOutputStream buffer = null;
try { in = new FileInputStream(getTileFile(x, y, zoom));
buffer = new ByteArrayOutputStream();
int nRead;
byte[] data = new byte[BUFFER_SIZE];
while ((nRead = in .read(data, 0, BUFFER_SIZE)) != -1) {
buffer.write(data, 0, nRead);
}
buffer.flush();
return buffer.toByteArray();
} catch (IOException e) {
e.printStackTrace();
return null;
} catch (OutOfMemoryError e) {
e.printStackTrace();
return null;
} finally {
if ( in != null)
try { in .close();
} catch (Exception ignored) {}
if (buffer != null)
try {
buffer.close();
} catch (Exception ignored) {}
}
}
private File getTileFile(int x, int y, int zoom) {
File sdcard = Environment.getExternalStorageDirectory();
String tileFile = "/TILES_FOLDER/" + zoom + '/' + x + '/' + y + ".png";
File file = new File(sdcard, tileFile);
return file;
}
}
Add TileOverlay to your GoogleMap instance
...
map.setMapType(GoogleMap.MAP_TYPE_NONE);
TileOverlayOptions tileOverlay = new TileOverlayOptions();
tileOverlay.tileProvider(new CustomMapTileProvider());
map.addTileOverlay(tileOverlay).setZIndex(0);
...
