Question

我正在创建一个可以将视频从服务器流式传输到Android移动设备的Android应用程序。我有正确的图像流和工作，但15秒后应用程序崩溃。我设法跟踪到Throwing OutOfMemoryError。我尝试回收位图后，我传递一个接口，将其带到线程显示它但我得到错误＆＃34;无法重复使用回收的Bitmap＆＃34;。我不确定如何修复此错误，即使斜倚也会修复它。

                    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//
                        }

                    }

我设法跟踪行的内存错误＆＃34; byte [] data = new byte [size + 1];＆＃34;但经过研究后，我得到了由位图引起的印象。

有没有其他人遇到过这个问题，并设法修复它？对此的任何帮助都会很棒：D

在Android 5上有类似问题。将图像移动到/ 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中的大图像，但您的设备是xxxhdpi，那么Android将获取mdpi中可用的图像并尝试将其缩放以匹配xxxhdpi，这可能会占用太多内存。但是/ drawable-nodpi中的图像没有缩放，它们按原样使用。

Android在App上抛出OutOfMemoryError
