Failure delivering result to activity for android.media.action.IMAGE_CAPTURE on onActivityResult after first time working

Question

I am having a bit of trouble finding the solution to my problem. This is the third day working on it (not that I work on it all day) but still I am unable to fix it. I am adding a function to my app which is taking a photography, shorten it, compressing it and converting it to Base64 so I can send it as part of the information for a document. I have been able to do all of it but I am having two problems that I suppose are related to each other. The first one and the one I am having troubles with is that if after taking the photography successfully the user decides that he needs to change it by taking another photography a second time, the app crashes. Sometimes I have been able to take a second photography but a third time the app crashes. The user can decide how many pictures wants to take for finally deciding what to send, so I am not planing on limiting him to just take one. I am thinking that it has to do with memory leaks or something with the Activity lifecycle (which is also related to the memory as I understand) that gives me the problem. The second problem is that if the user decides to take a photography and is taken successfully, then decides to take another but later he decides to not take it giving a resultCode = 0 as expected, the Activity seems to be refreshed and all the EditText data stays intact but the previous photography is not shown. I could get it back in the onResume callback but I am not sure if there is something better to do.

Here are the snippets to my code:

public void tomarFotografia(View view) {
    Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    if (cameraIntent.resolveActivity(getPackageManager()) != null) {
        File photoFile = null;
        try {
            photoFile = createImageFile();
        } catch (IOException e) {
            e.printStackTrace();
        }
        if (photoFile != null) {
            Uri photoURI = FileProvider.getUriForFile(this, "com.thesageelder.pmt.remisiones", photoFile);
            cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
//              cameraIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
//              cameraIntent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);

            List<ResolveInfo> resolvedIntentActivities = getPackageManager().queryIntentActivities(cameraIntent, PackageManager.MATCH_DEFAULT_ONLY);
            for (ResolveInfo resolvedIntentInfo : resolvedIntentActivities) {
                String packageName = resolvedIntentInfo.activityInfo.packageName;
                grantUriPermission(packageName, photoURI, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
            }

            startActivityForResult(cameraIntent, CAMERA_REQUEST);
        }
    }
}

private File createImageFile() throws IOException {
    File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
    File image = File.createTempFile(
            "RemisionPMT" + new SimpleDateFormat("yyyy-MM-dd_HH-mm-ss", Locale.US).format(Calendar.getInstance().getTime()),
            ".jpg",
            storageDir
    );
    currentPhotoFile = image.getAbsolutePath();
    return image;
}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {
        File photoFile = new File(currentPhotoFile);
        try {
            Bitmap fullPhoto = MediaStore.Images.Media.getBitmap(getContentResolver(), Uri.fromFile(photoFile));

            float aspectRatio = fullPhoto.getWidth() / (float) fullPhoto.getHeight();
            int w = 1024;
            int h = Math.round(w / aspectRatio);

            ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
            Bitmap.createScaledBitmap(fullPhoto, w, h, true).compress(Bitmap.CompressFormat.JPEG, 70, byteArrayOutputStream);
            byte[] byteArray = byteArrayOutputStream.toByteArray();

            EncodedPhoto = Base64.encodeToString(byteArray, Base64.DEFAULT);

            try {
                ExifInterface exif = new ExifInterface(currentPhotoFile);
                int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, 1);
                int rotationDegrees = 0;
                switch (orientation) {
                    case ExifInterface.ORIENTATION_ROTATE_90:
                        rotationDegrees = 90;
                        break;
                    case ExifInterface.ORIENTATION_ROTATE_180:
                        rotationDegrees = 180;
                        break;
                    case ExifInterface.ORIENTATION_ROTATE_270:
                        rotationDegrees = 270;
                        break;
                }

                Bitmap photoThumnail = ThumbnailUtils.extractThumbnail(BitmapFactory.decodeFile(currentPhotoFile), fullPhoto.getScaledWidth(getResources().getDisplayMetrics()) / 4, fullPhoto.getScaledHeight(getResources().getDisplayMetrics()) / 4);

                if (rotationDegrees != 0) {
                    Matrix matrix = new Matrix();
                    matrix.postRotate(rotationDegrees);
                    photoThumnail = Bitmap.createBitmap(photoThumnail, 0, 0, photoThumnail.getWidth(), photoThumnail.getHeight(), matrix, true);
                }

                ivFotoPreview.setImageBitmap(photoThumnail);
            } catch (Exception e) {
                e.printStackTrace();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

And this is the logcat:

I have placed a breakpoint in the very first line in the onActivityResult super.onActivityResult(requestCode, resultCode, data); and the app crashes without even stopping there. I have no idea what is the problem and being unable to debug it, I finally decide to ask here after some days searching for it. I think that all the other questions and answers I have read are related to not managing the result code or not reading correctly the data portion of the delivery result for the Activity. In my case I am expecting a resultCode different to -1 from the user and the data portion returns null since I want the full photography (since I found no way to having it from the data's extras).

Any help would be appreciated and sorry for the long question, I hope that writing this much detail would help understand my problem.

Not sure if it helps or not, but I am using an LG L70 with KitKat 4.4.2 to test it. Maybe with a more powerful device I would not have the problem, but the devices that the users are going to use wont be that more powerful.

Regards,

PD1: I do have the permission for <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> and <uses-permission android:name="android.permission.CAMERA"/>

PD2: I am leaving the entire camera function that I used here for some one that may need help with the camera and the FileProvider, additional to the previous code, it is needed that this is added to the Manifest:

<provider
    android:name="android.support.v4.content.FileProvider"
    android:authorities="[package]"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/file_paths"></meta-data>
</provider>

and a XML resource file file_paths.xml with this:

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="RemisionesPMT" path="Android/data/[package]/files/Pictures" />
</paths>

It took me six hours to figure it out.
