Android camera crash

Android
1

Hi,

I’m trying to use the camera on my android phone (Samsung S7). I call this code:

void open() {
    CameraDevice::openDeviceAsync(0, [this] (CameraDevice *device, const String &) {

        if(!device)
            return;

        device->onErrorOccurred = [] (const String &errorMessage) {
            std::cout << errorMessage << std::endl;
        };

        setPreview(device->createViewerComponent());
    });
}


void setPreview(Component *preview) {

    if(!preview)
        return;

    preview->setBounds(getLocalBounds());
    addChildAndTakeOwnerShip(preview);
}

The error callback is not called. First I got the following stacktrace. Then I checked out the recent commit from the development branch. Now it just crashes without breaking at a crash point in debug.

When I still got the crash break, it was on this line:
https://github.com/WeAreROLI/JUCE/blob/master/modules/juce_gui_basics/native/juce_android_Windowing.cpp#L466

I can run this code on my Mac. It opens the webcam and displays a preview. My phone is running Android 8.0.0, API 26.

Ok and before I send this I now found the CameraDemo. This crashes the same. (and btw: The “Camera required” setting is not enabled by default in the demo).

Also crashing on Samsung J5 with Android 8.1.0. (my App and CameraDemo).

Edit: Ok so it is working with a Huawei Mate20 and Android 9.
Edit2: And also working on iPad mini (although I again had to activate the camera request in Projucer first) Is it possible this is a Samsung specific problem? I don’t have any more devices to test with.

I’ve tested the CameraDemo on a Moto G6 Plus running Android 8 and a Samsung Galaxy S5 Neo running Android 6 and neither are crashing.

The callstack isn’t much use for debugging Android devices, can you paste the output of the Logcat window instead?

That looks more promising:

The problem is probably related to this:

Seems like it’s a known problem with Samsung devices running Android 8. I’ll add investigating this further to our backlog but I’m afraid it’s not particularly high priority at the moment.
