I am trying to take a picture in Android using an Uri. But I am struggeling getting the bitmap from the created Uri. I always get a null-Object from my Uri.

Uri imgUri;
File newfile;
public static Button camButton;
public static ImageView img;
public static TextView text;

public void photo(Button cB, ImageView im, TextView tv) 

 text = tv;
 camButton = cB;
 img = im;

 camButton.setOnClickListener(new View.OnClickListener() 
 public void onClick(View v) 

 final String dir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES) + "/picFolder/";
 File newdir = new File(dir);
 newdir.mkdirs();
 String file = dir + "test" + ".png";
 newfile = new File(file);
 try 
 newfile.createNewFile();
 catch (IOException e) 
 

 imgUri = FileProvider.getUriForFile(MainActivity.this,
 BuildConfig.APPLICATION_ID + ".provider",
 newfile);

 Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
 cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, imgUri);
 startActivityForResult(cameraIntent, TAKE_PHOTO_CODE);
 
 );


@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) 
 super.onActivityResult(requestCode, resultCode, data);

 if (requestCode == TAKE_PHOTO_CODE && resultCode == RESULT_OK) 

 Uri imageUri = FileProvider.getUriForFile(this, this.getApplicationContext().getPackageName() + ".provider", newfile);

 Bitmap bitmap = null;
 try 
 bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), imageUri);
 catch (Exception e) 
 e.printStackTrace();
 

 bitmap = Bitmap.createBitmap(bitmap,0,((bitmap.getHeight()-bitmap.getWidth()))/2,bitmap.getWidth(),bitmap.getWidth());
 bitmap = Bitmap.createScaledBitmap(bitmap, 64, 64, true);
 img.setImageBitmap(bitmap);

 

I am getting the error Could not write image : java.io.FileNotFoundException: open failed: ENOENT (No such file or directory)
And as a result of this the bitmap cannot be loaded and my bitmap is null, so that i receive a NullpointerException

try with this: 
@Override
 protected void onActivityResult(int requestCode, int resultCode, Intent data) 
 super.onActivityResult(requestCode, resultCode, data);

 if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) 

 Uri selectedImage = data.getData();
 Bitmap photo = null;
 try 
 photo = MediaStore.Images.Media.getBitmap(getContentResolver(), selectedImage);
 catch (IOException e) 
 e.printStackTrace();
 

 ByteArrayOutputStream baos = new ByteArrayOutputStream();

 photo.compress(Bitmap.CompressFormat.JPEG, 100, baos);

 byte b = baos.toByteArray();

 String encodedImage = Base64.encodeToString(b, Base64.DEFAULT);
 byte decodedString = Base64.decode(encoded, Base64.DEFAULT);
 Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);
 CircularImageView imageView = findViewById(R.id.profileimage);
 imageView.setImageBitmap(decodedByte);
