frame.acquireCameraImage().close() triggers crash #352

Closed itanbp closed 6 years ago

itanbp commented 6 years ago

Hi, I added the following code to ARCore sample app. When the app loads it Immediately crashes.

try (final Image image = frame.acquireCameraImage()) {
    if (image.getFormat() == ImageFormat.YUV_420_888) {
        image.close();
    }
} catch (NotYetAvailableException e) {
    Log.e("TAG", e.getMessage());
}

When commenting out image.close(); the app loads and works.

That looks like it should be valid. We're investigating.

inio commented 6 years ago

We can reproduce this failure. Thank you for the report.

inio commented 6 years ago

Whoops, looks like our close() method is not idempotent, so your code:

try (final Image image = frame.acquireCameraImage()) {
    if (image.getFormat() == ImageFormat.YUV_420_888) {
        image.close();
    }
}

Will end up closing the image twice: once at the literal image.close() call and once when the try-with-resources block exits.

Remove the inner call and it should stop crashing.

@inio thanks for the detailed answer

inio commented 6 years ago

Sounds like this is resolved. Feel free to reopen if I'm not reading your response correctly.

fredsa commented 6 years ago

Image.close() is now idempotent, as of version 1.3.0.
