Android PhotoEditor send Bitmap in Intent

Good morning, I'm using this Github library: https://github.com/burhanrashid52/PhotoEditor as photo editor. I have a GalleryFragment in which user choose image from his gallery, the I pass correctly the image to the EditImageActivity where user can apply sticker, filters, ecc. and then clicking on a button, user can pass the edited image to InfoActivity, where he can add other info and publish the image.
The problem is that when user edits an image and pass it to InfoActivity it is shown the original image without changes, and also when he publishes it, the image saved is the original, not the modified.
I'm trying to use Bitmap to do that:
This is the code of EditImageActivity where I try to send the edited image in a intent to InfoActivity:
ByteArrayOutputStream stream = new ByteArrayOutputStream();
Bitmap bmp =((BitmapDrawable)mPhotoEditorView.getSource().getDrawable()).getBitmap();
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();
Intent intent = new Intent(EditImageActivity.this, InfoActivity.class);
intent.putExtra("imm", byteArray);
startActivity(intent);
And this is the piece of code of InfoActivity, where I try to retrieve the intent with the edited image from EditImageActivity, to show it in a ImageView:
byte[] byteArray = getIntent().getByteArrayExtra("imm");
assert byteArray != null;
Bitmap bmp = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);
immagine.setImageBitmap(bmp);
So it works when user doesn't edit image, while when he edits image, it shows the original.
I think that the problem is in this code (the code that I use in EditImageActivity to get a bitmap of the edited image), because it passes the original image instead of the modified image:
Bitmap bmp =((BitmapDrawable)mPhotoEditorView.getSource().getDrawable()).getBitmap();
Can someone help me please?

Yes, it seems that the problem is when you fetch the edited image from your PhotoEditorView. If you see the documentation, to retrieve this image, is necessary to implement the next approach:
PhotoEditor.saveAsFile(filePath, new PhotoEditor.OnSaveListener() {
#Override
public void onSuccess(#NonNull String imagePath) {
Log.e("PhotoEditor","Image Saved Successfully");
}
#Override
public void onFailure(#NonNull Exception exception) {
Log.e("PhotoEditor","Failed to save Image");
}
});
So the library needs a file to save it and if is success, then returns the path file, with the path file you needs to create the Bitmap object.

taken from android camera image original resolution

This code gives me image taken from android camera ,however,its size and resolution format of the thumnail.
Bitmap photo = (Bitmap) data.getExtras().get("data");
How can I get the original image with the original size and resolution
Thank you

Bitmap photo = (Bitmap) data.getExtras().get("data");
this code gives you only thumnail image.To get the original image u need to use EXTERNAL_STORAGE which image saved there. (Code is something like this)
File storageDir = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES);
For more information take a look at here

Create a Temp File in externalCacheDir and put the URI in your Intent which starts the camera, after image shooting the image is stored in that file.
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File tempCaptureFile = ImageAccessor.createTempFile(getActivity(), TEMP_CAPTURE_FILE_NAME);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(tempCaptureFile));
if (takePictureIntent.resolveActivity(getActivity().getPackageManager()) != null) {
getActivity().startActivityForResult(takePictureIntent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
}
ImageAccessor is just a helper class to create a File in externalCacheDir.

Bitmap photo = (Bitmap) data.getExtras().get("data");
this line only return thumbnal image reffer bellow link
android camera intent

Android share intent on specific application and from Bitmap resource

I'm trying to share from my app to Hyves using share intent. If I have hyves app installed and share from gallery it switch to hyves app, and upload image correctly to hyves, so it should work.
Problem is, I can't find it documented how should proper intent for hyves work, but I assume that gallery uploads images only, so I have this:
Bitmap image = BitmapFactory.decodeFile(MyGlobals.INSTANCE.activeSetting.f_image_path);
It's line of code where I pull my "active" or "selected" image within my app. At this point image is saved to SD Card, so I might read uri instead of decoding file, but I want it this way to have same approach for both hyves and facebook.
Then I call:
Intent hyvesIntent = new Intent(Intent.ACTION_SEND);
hyvesIntent.setPackage("com.hyves.android.application");
hyvesIntent.setType("image/jpeg");
hyvesIntent.putExtra("image", image);
startActivityForResult(hyvesIntent, 666);
First of all, I'm not sure if setPackage is OK to be used here, but I'm checking if this package exist to enable / disable share, and this is package name that is visible.
I need Activity result to then notify that Image is shared or not.
What happens here it starts the Hyves app, but I get full white screen, and then the Hyves app times out.
So, Can I use Bitmap in intent, and is it OK to setPackage or should I setClass?
Tnx

Maybe you can not put the bitmap directly in the intent.
First convert the bitmap into a byte array than send another side and convert into bitmap
//convert bitmap to bytearray
public static byte[] getBitmapAsByteArray(Bitmap bitmap, boolean type) {
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
if (type) {
bitmap.compress(CompressFormat.PNG, 0, outputStream);
} else {
bitmap.compress(CompressFormat.JPEG, 0, outputStream);
}
return outputStream.toByteArray();
}
//convert bitmap to bytearray
public static Bitmap getBitmap(byte[] imgByte){
Bitmap bm = BitmapFactory.decodeByteArray(imgByte, 0, imgByte.length);
return bm;
}
//than intent
Intent hyvesIntent = new Intent(Intent.ACTION_SEND);
hyvesIntent.setPackage("com.hyves.android.application");
hyvesIntent.setType("image/jpeg");
hyvesIntent.putExtra("image", getBitmapAsByteArray(image,true));
startActivityForResult(hyvesIntent, 666);
I hope that is right way to put image

Passing the Image in PutExtra in Android

I want to pass the Background Image that I have set to Button in PutExtra() with intent object into another Class.
Can anybody know how to do that ?
Thanks

Sender Activity:
Bitmap bitmap = BitmapFactory.decodeResource
(getResources(), R.drawable.sticky_notes); // your bitmap
ByteArrayOutputStream bs = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 50, bs);
intent.putExtra("byteArray", bs.toByteArray());
Reciever Activity:
if(getIntent().hasExtra("byteArray")) {
ImageView imv= new ImageView(this);
Bitmap bitmap = BitmapFactory.decodeByteArray(
getIntent().getByteArrayExtra("byteArray"), 0, getIntent().getByteArrayExtra("byteArray").length);
imv.setImageBitmap(bitmap);
}

Intent can keep only 40 kbytes. If you can zip your images less then 40 kbytes - you can put it into extras

intent.putExtra("imageData", bitmap)
better approach is to create a link instead of passing directly bitmap.
intent.putExtra("image_url",R.drawable.image);

try this...
first get image in bitmap.
Bitmap tileImage = BitmapFactory.decodeResource(getResources(), R.drawable.floore);
Conver it in byte array.
ByteArrayOutputStream stream = new ByteArrayOutputStream();
photo.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();
Bundle b = new Bundle();
b.putByteArray("camara",byteArray);
Intent intent3 = new Intent(this,Second.class);
intent3.putExtras(b);
startActivity(intent3);

You can pass Bitmap (since it's implementing Parcelable) if you're sure that it won't be deleted from memory (in other words - don't store Bitmaps like that).
Bitmap itself is just a small Java wrapper of native resources, so it won't take a lot of space.

Be careful when passing files that can be very large, such as a photo or gallery file. Even if you compress it, the size may exceed putExtra's acceptable limit. I suggest sending the image link or file path for a file from the gallery. In my app I always compress my files as max as I can, but there was always one that crashs the app.
Intent intent = new Intent(getActivity(), PhotoViewActivity.class);
intent.putExtra("url", url);
//OR file path
intent.putExtra("path", path);
startActivityForResult(intent,PHOTO_VIEW_REQUEST);
In that case on PhotoViewActivity
String url = getIntent().getStringExtra("url");
String path = getIntent().getStringExtra("path");
if(url != null && !url.isEmpty()){
//Get using Picasso or other framework
}else if(path != null && !path.isEmpty()){
//In my case I transform in Bitmap
//see this link for more detail : https://stackoverflow.com/questions/16804404/create-a-bitmap-drawable-from-file-path
}else{
//Throw exception and close activity
}
How transform path in Bitmap:
Create a Bitmap/Drawable from file path

Android: Not able to get original photo captured by camera (Able to read compress photo only)

In my application I capture photo by android camera and then I want to send it to the server. For this I use Client Socket programming. I convert the capture photo into bytearray(byte[]) and then send it to the server. Every thing work perfactally.
Problem is there I am not able to send original photo to the server. Thumbnail photo is sended by the android mobile phone. But when I capture photo by the camera then original photo is there in Gallery.
How to get this original photo to use in my application?
My Code:
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra("outputFormat",Bitmap.CompressFormat.JPEG);
cameraIntent.putExtra("return-data", true);
startActivityForResult(Intent.createChooser(cameraIntent, "Select Picture"),
CAMERA_REQUEST);
And in onActivityResult method:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_REQUEST) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
// byte[] a = (byte[]) data.getExtras().getByteArray("data"); // I also use this but not work
ByteArrayOutputStream bos = new ByteArrayOutputStream();
photo.compress(CompressFormat.JPEG, 100, bos);
byte[] bitmapdata = bos.toByteArray();
}
}
in bitmapdata photo is there but compressed photo not the original.
Some of people say that, change quality field of compress(CompressFormat.JPEG, 100, bos); in between 0 to 100 but nothing will happen.
-- >> is there any other way also to get original photo which is captured by the camera
-- >> When The photo is in folder of my computer then I read this photo in the file by giving the path. ex- File file = new File(c:\newphoto\image.jpg); . can I use this code in android to read original photo because I know the name and location of photo. If yes then what is the path to read photo in gallery. Is this work if I give path as: \DCIM\Camera\photoName.jpg.
-- >> Or some change need in my current code and it will work fine?

You are using the Intent to capture the image using ACTION_IMAGE_CAPTURE. If you normally starts your camera using Intent then it will return image as a bitmap in onActivityResult() but it will be for thumbnail purpose.
If you want to get full resolution image from the camera then you should provide a file with the intent which you are firing to start the camera activity.
You can do like below
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
File out = Environment.getExternalStorageDirectory();
out = new File(out, imagename);
i.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(out));
startActivityForResult(i, CAMERA_RESULT);
Here there is a MediaStore.EXTRA_OUTPUT parameter which takes a Uri of the file in which you want your camera to write a images.
For more information you can refer below example
