Android 在 App 上抛出 OutOfMemoryError

Question

我正在制作一个 android 应用程序，可以将视频从服务器流式传输到 android 手机。我可以正常传输图像并正常工作，但 15 秒后应用程序崩溃。我设法将此跟踪到 Throwing OutOfMemoryError。在我将位图传递给它一个接口(interface)以将其带到线程以显示它之后，我尝试回收位图，但我收到错误“无法重用回收的位图”。我不确定如何修复此错误，或者即使倾斜它也能修复它。

                    int read_count = 1;
                    long start_time = System.currentTimeMillis();
                    long timeout = 10000;
                    boolean timed_out = false;

                    byte[] data = new byte[size + 1];
                    while (read_count < size && !timed_out)
                    {
                        int len = in.read(data, read_count, size - read_count);
                        read_count += len;
                        timed_out = (System.currentTimeMillis() - start_time) >= timeout;
                    }
                    data[0] = (byte)0x89;

                    if (read_count == size)
                    {
                        final boolean is_left = (side == 0);
                        final byte[] tmp = data;
                        Bitmap Image_data = null;
                        System.out.println(tmp.length);
                        if (Listener != null)
                        {
                            Image_data = BitmapFactory.decodeByteArray(tmp, 0, tmp.length);

                            Listener.OnNewImageListenerBitmap(Image_data, is_left);

                          // this is where i tried recycling it//
                        }

                    }

我设法将内存错误跟踪到行“byte[] data = new byte[size + 1];”但经过研究，我得到的印象是位图造成的。

有没有其他人遇到过这个问题并设法解决了它？对此的任何帮助都很棒 :D

谢谢

在 Android 5 上有类似的问题。将您的图像移动到/drawable-nodpi 而不是/drawable。

编辑:我认为这与使用当前设备 DPI 自动缩放图像有关。例如，如果您只有/drawable-mdpi 中有大图像，但您的设备是 xxxhdpi，那么 Android 会获取 mdpi 中可用的图像并尝试将其放大以匹配 xxxhdpi，这会占用太多内存。但是/drawable-nodpi 中的图像没有缩放，它们按原样使用。
