The similar SO question-answers is crashing my app.
I am taking a photo through my camera intent and sending it to my php server over net which is then saving it to a directory. It is working fine. But the photo being saved is of compromised quality (~20KB).
I know my mistake. I read Android documentation to realize I am actually sending the photo thumbnail instead of the photo itself. Here is my code
Open Camera Intent to take a photo.
addImage = (ImageButton) findViewById(R.id.imageButton);
addImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
}
Receiving the Image.
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK){
photo = (Bitmap) data.getExtras().get("data");
addImage.setImageDrawable(null);
addImage.setBackgroundColor(Color.parseColor("#ffffff"));
addImage.setImageBitmap(photo);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
photo.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] photoByte = baos.toByteArray();
encodedImage = Base64.encodeToString(photoByte,Base64.DEFAULT);
}
}
What do I want? I simply want to convert my original image (and not the thumbnail) to Base64 encoded string (Just like what I did with the thumbnail).
Any help will be appreciated.
[ Feel free to suggest edits. :) ]

You do not have an "original image", because you did not include EXTRA_OUTPUT in your ACTION_IMAGE_CAPTURE Intent. Add that, and then you have your full-size image (except with buggy camera apps):
