Question

我正在使用Play Services愿景：“ com.google.android.gms：play-services-vision：15.0.2”

当我为CameraSource对象调用方法“ takePicture”时，应用程序经常崩溃

mCameraSource.takePicture(null, new CameraSource.PictureCallback() {
    @Override
    public void onPictureTaken(byte[] bytes) {
        try {
            FileUtils.saveImage(bytes, String.valueOf(PHOTO_NAME), "png");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
});

我尝试了从工作线程和UI线程进行调用，但结果相似。也许有人遇到这个问题？
