每次加载名为ProductActivity的某些活动时，都会遇到以下错误：

现在我应该如何优化资源以便摆脱这个错误？

我应该调整服务器上的图像大小，还是应该在我的应用程序中调整它们的大小以免除所有这些。目前，我正在使用毕加索来加载我的应用程序中的图像。

您正在尝试加载15694612字节= 15 MB的称重图像，这太大了。如果没有选项可以使用单独的缩减采样资源，那么您的选项是downsample it programmatically，然后加载它。

private Bitmap downscaleBitmapUsingDensities(final int sampleSize, final int imageResId) {
  final Options bitmapOptions = new Options();
  bitmapOptions.inDensity = sampleSize;
  bitmapOptions.inTargetDensity = 1;
  final Bitmap scaledBitmap = BitmapFactory.decodeResource(getResources(), imageResId, bitmapOptions);
  scaledBitmap.setDensity(Bitmap.DENSITY_NONE);
  return scaledBitmap;
}

sampleSize是一个整数，它指定在将源位图加载到内存之前对源位图进行缩减采样的次数。
