Answer 1

i suggest you to use this library Android-Image-Cropper by ArthurHub, it gives you a plenty of cropping choices (shape , size ,....) , and it also give you the choice of taking new picture or using one from the gallery

    int myColor;
    if(Build.VERSION.SDK_INT >= 21){
        myColor = ContextCompat.getColor(this, R.color.white);
    }
    else{
        myColor=getResources().getColor(R.color.white);
    }
    CropImage.activity()
            .setActivityMenuIconColor(myColor)
            .setAllowRotation(true)
            .setFixAspectRatio(true)
            .setAspectRatio(3, 2)
            .setCropShape(CropImageView.CropShape.RECTANGLE)
            .setActivityTitle("Selection d'image")
            .start(this);

and you have to handle the result :

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

    if(requestCode== CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE){

     CropImage.ActivityResult result = CropImage.getActivityResult(data);
        if (resultCode == RESULT_OK) {
            Uri resultUri = result.getUri();
            Bitmap bitmap = null;
            try {
                bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), resultUri);

                String string = resultUri.toString();
                ByteArrayOutputStream baos = new ByteArrayOutputStream();
                bitmap.compress(Bitmap.CompressFormat.JPEG, 40, baos);


            } catch (IOException e) {
                e.printStackTrace();
            }


        } else if (resultCode == CropImage.CROP_IMAGE_ACTIVITY_RESULT_ERROR_CODE) {
            Exception error = result.getError();
        }
    }

}
