I couldn't find the solution for my issue. My MainActivity creates a pdf file, the user adds some text via EditText and closes it, no problem with that. Then I have a secondary activity that is calling the MediaStore.ACTION_IMAGE_CAPTURE to take pictures. Once a picture is taken, I'd like to know how I can get this just-captured image into that pdf.
I know I have to reopen the pdf, that is no problem, since I have the pdf file name saved in a variable. The major problem that I see is that I don't know how to programmatically get the file name of the picture, once it is automatically named after "yyyyMMdd_hhMMss.jpg". So how to get the file name from a picture taken by my secondary activity?
*EDIT - Showing code:
From MainActivity:

@Override

if (resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
Bitmap mImageBitmap = (Bitmap) extras.get("data");
iv.setImageBitmap(mImageBitmap);
String fpath = Environment.getExternalStorageDirectory() + "/CoManut/sample.pdf";
File file = new File(fpath);
if (!file.exists()) {
try {
file.createNewFile();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Document document = new Document();
try {
PdfWriter.getInstance(document, new FileOutputStream(fpath));
} catch (FileNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (DocumentException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
document.open();
ByteArrayOutputStream stream = new ByteArrayOutputStream();
mImageBitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
Image myImg = null;
try {
myImg = Image.getInstance(stream.toByteArray());
} catch (BadElementException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (MalformedURLException e) {
// TODO Auto-generated catch block

} catch (IOException e) {
// TODO Auto-generated catch block

}
myImg.setAlignment(Image.MIDDLE);
try {
document.add(myImg);
} catch (DocumentException e) {
// TODO Auto-generated catch block

}
document.close();
}
}
// Button to go back to the MainActivity
public void onclickButton2(View view) {
PhotoActivity.this.finish();
}
@Override
protected void onDestroy() {
super.onDestroy();
}
}
Override your onActivitResult() method in your Main Activity
Here you will get the image bitmap from (Intent Data)
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
Bitmap mImageBitmap = (Bitmap) extras.get("data");
}
}
Now you have the bitmap. You can add bitmap image like below using the iText Library
try {
ByteArrayOutputStream stream = new ByteArrayOutputStream();
mImageBitmap.compress(Bitmap.CompressFormat.PNG, 100, stream); // Try with Bitmap.CompressFormat.JPG also
Image image = Image.getInstance(stream.toByteArray());
document.add(image);
}catch(IOException ex){
ex.printStackTrace();
}
Update1
Your onActivityResult() should look like this.
Note Make sure you have WRITE_EXTERNAL_STORAGE permissions in your menifest.xml file.
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
Bitmap mImageBitmap = (Bitmap) extras.get("data");
img.setImageBitmap(mImageBitmap);
String fpath = Environment.getExternalStorageDirectory()
.getAbsolutePath() + "/sample.pdf";
File file = new File(fpath);
if (!file.exists()) {
try {
file.createNewFile();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Document document = new Document();
try {
PdfWriter.getInstance(document, new FileOutputStream(fpath));
} catch (FileNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (DocumentException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
document.open();
ByteArrayOutputStream stream = new ByteArrayOutputStream();
mImageBitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
Image myImg = null;
try {
myImg = Image.getInstance(stream.toByteArray());
} catch (BadElementException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
myImg.setAlignment(Image.MIDDLE);
try {
document.add(myImg);
} catch (DocumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
document.close();
}
}
This will create a sample.pdf file in your sdcard and add Image bitmap into it.
Hope this helps. I tested it here its working. :)
