Question

我有加载位图的代码：

    public void run() {
      final Bitmap bitmap;
      try {
        bitmap = MediaStore.Images.Media.getBitmap(ab.getContentResolver(), tryUri);
        BitmapDrawable bd = new BitmapDrawable(ab.getResources(), bitmap);
        cachePut(urlStr, bd);

        ab.runOnUiThread(new Runnable() {
          @Override
          public void run() {
            // make sure the tag is still the one we set at the beginning of this function
            if (toSet.getTag() == urlStr) {
              toSet.setImageBitmap(bitmap);
            }
          }
        });
      } catch (FileNotFoundException e) {} catch (IOException e) {}
    }

但是我收到了这个错误：

我试过了

bitmap.recycle（） - ＆gt;我无法回收它，因为我的drawableBitmap使用此位图。

添加缓存层+使其非常小 - ＆gt;它仍然崩溃。

你还有什么建议？如何识别代码中的确切原因导致OOM错误？

Answer 1

显然你的cachePut（urlStr，bd）;最近没有正确释放缓存的图像，您需要处理缓存大小，并确保收集垃圾，以便在需要时获取内存。最佳选择是周参考。此外，谷歌番石榴提供了使用弱引用的特殊缓存工具。

无论如何，如果你决定不使用它，你需要手动处理缓存清理......

缓存或回收帮助位图加载内存不足异常
