OutOfMemory error with runOnUiThread and Flir One SDK

Question

I'm trying to save the frame received on FrameProcessor.Delegate.onFrameProcessed.

If I try to use runOnUiThread inside the Thread that uses renderedImage.getFrame().save(...), I get the following exception:

AndroidRuntime: Error reporting crash

This is the method that does the original thread:

private FrameProcessor.Delegate frameProcessorDelegate = new FrameProcessor.Delegate() {
    @Override
    public void onFrameProcessed(final RenderedImage renderedImage) {
        //Capture this image if requested
        if (imageCaptureRequested) {
            imageCaptureRequested = false;
            setProgressVisibility(VISIBLE);

            new Thread(new Runnable() {
                public void run() {
                    String path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).toString();
                    SimpleDateFormat sdf = new SimpleDateFormat("yyMMdd-HHmmss", Locale.getDefault());
                    String formatedDate = sdf.format(new Date());
                    String fileName = formatedDate + ".jpg";
                    try {
                        lastSavedPath = path + "/" + fileName;

                        renderedImage.getFrame().save(new File(lastSavedPath), RenderedImage.Palette.Iron, RenderedImage.ImageType.BlendedMSXRGBA8888Image);

                        toggleConfirmPhotoScreen(true, lastSavedPath);
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }
            }).start();
        }
    }
};

The method that uses runOnUiThread:

private void toggleConfirmPhotoScreen(final boolean show, final String lastSavedPath) {
    //works until here
    Log.d("ExampleApp", "toggleConfirmPhotoScreen");
    ((Activity) getContext()).runOnUiThread(new Runnable() {
        @Override
        public void run() {
            //NEVER REACHES HERE
            Log.d("ExampleApp", "        " + show + " CancelConfirmScreen");
        }
    });
}

As you can see in the comments in the code, toggleConfirmPhotoScreen is called, but nothing inside runOnUiThread is, there is when I suppose the OutOfMemoryException occurs.
