Image.getBitmap() returning null?

Question

Consider this code:

Image img = chart.getExport().getImage().image(WIDTH, HEIGHT);

I would expect it to return the actual bitmap using this code:

img.getBitmap();

However, that returns null! How come I cannot retrieve the underlying bitmap? How is it generated?

Try with bitmap instead of getBitmap(). The following code seems to work fine for me here:

Bar bar = new Bar(tChart1.getChart());
bar.fillSampleValues();
bar.setColorEach(true);

tChart1.doInvalidate();
Image img = tChart1.getExport().getImage().image(400, 200);
MediaStore.Images.Media.insertImage(getContentResolver(), img.bitmap, "test.jpg", "test.jpg");
