OutOfMemoryError getting while converting an image to circular shaped one

Question

We are using an android ffi in kony for making an image into circular shape. Getting this

Log.d("ANDRO_ASYNC",String.format("catch Out Of Memory error"))

App is crashing with the below error log: Throwing OutOfMemoryError "Failed to allocate a 16793702 byte allocation with 5499006 free bytes and 5MB until OOM" Tried to give bitmap.recycle(); also but still same error.

code where we get the issue:

public class MainActivity
{

public String testStart(String base64)
{
    Log.i("testart-->>", "latest");
    String base = "";
    byte[] imageAsBytes = Base64.decode(base64.getBytes(), Base64.DEFAULT);
     Bitmap bitmap = BitmapFactory.decodeByteArray(imageAsBytes, 0, imageAsBytes.length);

    Bitmap circularBitmap = ImageConverter.getRoundedCornerBitmap(bitmap, 100);
    Log.i("testart-->>", "oustode");
    base = bitmapToBase64(circularBitmap);
    return base;

}
private String bitmapToBase64(Bitmap bitmap)
{
    try{

        ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();

        bitmap.compress(Bitmap.CompressFormat.PNG, 5, byteArrayOutputStream);
            byte[] byteArray = byteArrayOutputStream.toByteArray();

        System.gc();

        return Base64.encodeToString(byteArray, Base64.DEFAULT);
    }catch(OutOfMemoryError E){
        Log.d("ANDRO_ASYNC",String.format("catch Out Of Memory error"));
        //      E.printStackTrace();
        System.gc();

        return "";
    }
}
}
