Android support?

I tried to integrate your library into Android app, but the image is of type java.awt.image.BufferedImage, which is not available in Android. Any plans on development of this library?

I don't do any Android development, but feel free to submit patches!

@davidvavra my fellow colleague @vandac pointed out there is Android compatible version of zxing library, however this would require significant rework of sapyd library. Any plans to sponsor this effort?

At the end I took this approach in Settle Up app:

1. Your library is used only for generating payment string
2. Then I use this library for generating QR code: https://github.com/kenglxn/QRGen
3. Then I added border & "Qr platba" title using Android views:

<androidx.constraintlayout.widget.ConstraintLayout
                android:id="@+id/vQrSection"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:background="@color/c_white"
                app:layout_constraintStart_toStartOf="parent"
                app:layout_constraintTop_toTopOf="parent">

                <androidx.appcompat.widget.AppCompatImageView
                    android:id="@+id/vQr"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:layout_margin="16dp"
                    android:adjustViewBounds="true"
                    android:background="@drawable/qr_border"
                    android:padding="1dp"
                    app:layout_constraintStart_toStartOf="parent"
                    app:layout_constraintTop_toTopOf="parent"
                    tools:src="@drawable/img_premium_expired" />

                <androidx.appcompat.widget.AppCompatTextView
                    android:id="@+id/vQrText"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_marginStart="43dp"
                    android:layout_marginTop="-5dp"
                    android:background="@color/c_white"
                    android:paddingStart="8dp"
                    android:paddingEnd="8dp"
                    android:paddingBottom="16dp"
                    android:text="@string/qr_payment"
                    android:textAppearance="@style/InputFieldText"
                    android:textColor="@color/c_black"
                    app:layout_constraintStart_toStartOf="parent"
                    app:layout_constraintTop_toBottomOf="@+id/vQr" />
</androidx.constraintlayout.widget.ConstraintLayout>

It's not a generic solution and more like a workaround, but enough for my app. I don't have plans to invest time into generalizing it, but this post might help some Android developers.
