记一次系统的bug，yuvImage.compressToJpeg导致内存泄露

在做人脸识别的时候，发现内存一直增加，但是该释放的资源已经释放，经过跟厂家一起排查，是在compressToJpeg转换的时候导致的

原代码：：YuvImage yuvImage = new YuvImage(data, ImageFormat.NV21, size.width, size.height, null);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
yuvImage.compressToJpeg(new Rect(0, 0, size.width, size.height), 100, baos);
byte[] byteArray = baos.toByteArray();

后改成直接转成bitmap。

Bitmap yuv2Bitmap = BitmapUtils.yuv2Bitmap(data, size.width, size.height);

public static Bitmap yuv2Bitmap(byte[] data, int width, int height) {
    int frameSize = width * height;
    int[] rgba = new int[frameSize];

    for (int i = 0; i < height; i++) {
        for (int j = 0; j < width; j++) {
            int y = (0xff & ((int) data[i * width + j]));
            int u = (0xff & ((int) data[frameSize + (i >> 1) * width + (j & ~1) + 0]));
            int v = (0xff & ((int) data[frameSize + (i >> 1) * width + (j & ~1) + 1]));
            y = y < 16 ? 16 : y;

            int r = Math.round(1.164f * (y - 16) + 1.596f * (v - 128));
            int g = Math.round(1.164f * (y - 16) - 0.813f * (v - 128) - 0.391f * (u - 128));
            int b = Math.round(1.164f * (y - 16) + 2.018f * (u - 128));

            r = r < 0 ? 0 : (r > 255 ? 255 : r);
            g = g < 0 ? 0 : (g > 255 ? 255 : g);
            b = b < 0 ? 0 : (b > 255 ? 255 : b);

            rgba[i * width + j] = 0xff000000 + (b << 16) + (g << 8) + r;
        }
    }

    Bitmap bmp = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
    bmp.setPixels(rgba, 0, width, 0, 0, width, height);
    return bmp;
}  

观察了几天，并不会出现
