Low picture/image quality when capture from camera

Question

I have one problem. When I try to get picture from camera, the quality is very low. At first, capture the picture using camera, than save to the directory and at the same time get that picture and show in my app.The picture saved inside directory is a fine quality but when I get it from directory, the quality is low. below is my sample code :

public void onActivityResult(int requestCode, int resultCode, Intent intent) {

    if (requestCode == CAMERA_PIC_REQUEST) {  

        Bitmap thumbnail = (Bitmap) intent.getExtras().get("data");

        if (g==1)
        {
            ImageView myImage = (ImageView) findViewById(R.id.img5);
            myImage.setImageBitmap(thumbnail);

            View a = findViewById(R.id.img5);
            a.setVisibility(View.VISIBLE);

            ByteArrayOutputStream stream = new ByteArrayOutputStream();
            thumbnail.compress(Bitmap.CompressFormat.JPEG, 100, stream);

            byteArray1 = stream.toByteArray();
        }
}

any solution/suggestion? Thanks :)

The problem solved when I follow the code given by Antrromet below

I don't see you getting the photo from the directory anywhere? All I see is you use the bundled thumbnail, which, by the way, is prone to errors as in my experience not all devices actually return any "data" extra. The thumbnail will obviously not have the same size as the 'full' picture on your storage medium. — MH., Apr 30 '12 at 02:36
actually I call thecamera using this: Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST); what is your suggestion then to avoid the error?and how to get the actual size of picture? Thanks for your reply :) — ckng, Apr 30 '12 at 03:16
Best approach is probably to [supply the output path](http://stackoverflow.com/a/7529603/1029225) with the `Camera` intent. Alternatively you could also implement [your own photo capture logic](http://stackoverflow.com/a/4855261/1029225) (more work), or possibly use a [`FileObserver`](http://developer.android.com/reference/android/os/FileObserver.html) on the DCIM/Camera directory. — MH., Apr 30 '12 at 03:57

I have used the following code and this works perfectly fine for me.

            values = new ContentValues();
            values.put(MediaStore.Images.Media.TITLE, "New Picture");
            values.put(MediaStore.Images.Media.DESCRIPTION, "From your Camera");
            imageUri = getContentResolver().insert(
                    MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
            startActivityForResult(intent, PICTURE_RESULT);

and also

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        switch (requestCode) {

        case PICTURE_RESULT:
            if (requestCode == PICTURE_RESULT)
                if (resultCode == Activity.RESULT_OK) {
                    try {
                        thumbnail = MediaStore.Images.Media.getBitmap(
                                getContentResolver(), imageUri);
                        imgView.setImageBitmap(thumbnail);
                        imageurl = getRealPathFromURI(imageUri);    
                    } catch (Exception e) {
                        e.printStackTrace();
                    }

                }
        }
    }

and

public String getRealPathFromURI(Uri contentUri) {
        String[] proj = { MediaStore.Images.Media.DATA };
        Cursor cursor = managedQuery(contentUri, proj, null, null, null);
        int column_index = cursor
                .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        return cursor.getString(column_index);
    }

The above code works but somehow in OnActivityResult() -> the imageUri is shown null sometimes even though I've set imageUri while starting CameraActivity. @Antrromet – neaGaze Mar 25 '15 at 05:50
^ [SOLVED] -> declared the imageUri and ContentValues in the onCreate() method rather than onClick listener :D – neaGaze Mar 25 '15 at 09:42

cannot understand the use of - imageurl = getRealPathFromURI(imageUri); ? – Narendra Singh Dec 14 '15 at 13:13

Not working in Android 7.0. Checkout this: https://developer.android.com/training/camera/photobasics.html – Shohan Ahmed Sijan Apr 04 '17 at 07:33
@Antrromet any solution for Android N7.0? – Qadir Hussain Jul 04 '17 at 20:04
it takes too much time as the images size goes upto 14mb – Ashutosh Sagar Oct 29 '18 at 10:49
It is recommended to use this function "getRealPathFromURI" on Ui Thread, because it is a query to media store database. It might cause an ANR. – Cícero Moura Jul 23 '19 at 20:56

Anyone can enlighten me about the `imageurl` ? It is used as `imageurl = getRealPathFromURI(imageUri);` but not used anywhere else – Costin Jan 17 '20 at 07:53

Whats imageLocationUri = getRealPathFromURI(imageLocationUri); – Emmanuel Njorodongo May 25 '21 at 12:36

Solution to save a picture in a specific folder without lost quality

I FOUND THE SOLUTION:

//Create a new folder code:

 String path = String.valueOf(Environment.getExternalStorageDirectory()) + "/your_name_folder";
            try {
                File ruta_sd = new File(path);
                File folder = new File(ruta_sd.getAbsolutePath(), nameFol);
                boolean success = true;
                if (!folder.exists()) {
                    success = folder.mkdir();
                }
                if (success) {
                    Toast.makeText(MainActivity.this, "Carpeta Creada...", Toast.LENGTH_SHORT).show();
                }
            } catch (Exception ex) {
                Log.e("Carpetas", "Error al crear Carpeta a tarjeta SD");
            }

                            imgFoto.setImageBitmap(thumbnail);
                            imageurl = getRealPathFromURI(imageUri);
                        } catch (Exception e) {

                        }

                    }

// getRealPathFromUri

public String getRealPathFromURI(Uri contentUri) {
        String[] proj = {MediaStore.Images.Media.DATA};
        Cursor cursor = managedQuery(contentUri, proj, null, null, null);
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        return cursor.getString(column_index);
    }

In `takePic()` you accidentally added an asterisk and also u forgot `Uri imageUri;`. — phrogg, May 08 '19 at 16:36

Add the photo to a gallery . .

private void galleryAddPic() {
    Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
    File f = new File(currentPhotoPath);
    Uri contentUri = Uri.fromFile(f);
    mediaScanIntent.setData(contentUri);
    this.sendBroadcast(mediaScanIntent);
}
